  1. Predicting Proton-Induced Single Event Upsets Rates

    NASA Astrophysics Data System (ADS)

    Reed, Robert Andrew

    Microelectronic devices are susceptible to single event effects in some space radiation environments. A traversal by a single energetic particle that leads to a change in the information stored on a single memory element is known as a single event upset. The cross section for producing an upset can vary with the angle of incidence of the proton, depending on the dimensions of the sensitive volume and the critical charge. Satellites encounter a high proton flux region when they traverse the inner radiation belts in space. The goal of this research was to develop an algorithm for predicting proton-induced memory upset rates for orbits that cross these belts that includes the angular variations in the upset cross section. This required extending an existing Monte-Carlo code that simulates proton -induced spallation reactions in silicon to be capable of handling protons incident at any angle of incidence. These codes were used to predict upset cross sections. The radiation environment was modeled as a set of monoenergetic omnidirectional proton beams where the relative flux at each energy was predicted by AP8. The shielding that surrounds a device was assumed to be a six sided shell. Protons that traverse the shell will enter the device with a new energy. A shielding code was developed that translated each omnidirectional exposure into a new spectrum of energies. Each spectrum was used as input into the Monte-Carlo code which determined the angle-average upset cross section for that incident proton energy (i.e., the proton's energy before traversing the shielding). The upset rate was predicted from the cross section predictions and the flux prediction of AP8. Applying the codes to specific devices requires knowledge of the dimensions of the sensitive volume and the critical charge, i.e., the threshold energy that must be deposited in the sensitive volume to upset the device. These parameters were determined for four devices flown as part of the Microelectronic Package

  2. Comparison of single event upset rates for microelectronic memory devices during interplanetary solar particle events

    McKerracher, P. L.; Kinnison, J. D.; Maurer, R. H.

    Variability in the methods and models used for single event upset calculations in microelectronic memory devices can lead to a range of possible upset rates. Using heavy ion and proton data for selected DRAM and SRAM memories, we have calculated an array of upset rates in order to compare the Adams worst case interplanetary solar flare model to a model proposed by scientists at the Jet Propulsion Laboratory. In addition, methods of upset rate calculation are compared: the Cosmic Ray Effects on Microelectronics CREME code and a Monte Carlo algorithm developed at the Applied Physics Laboratory. The results show that use of a more realistic, although still conservative, model of the space environment can have significant cost saving benefits.

    Reductions in single-event (SE) upset (SEU) rates for sequential circuits due to temporal masking effects are evaluated. The impacts of supply voltage, combinational-logic delay, flip-flop (FF) SEU performance, and particle linear energy transfer (LET) values are analyzed for SE cross sections of sequential circuits. Alpha particles and heavy ions with different LET values are used to characterize the circuits fabricated at the 40-nm bulk CMOS technology node. Experimental results show that increasing the delay of the logic circuit present between FFs and decreasing the supply voltage are two effective ways of reducing SE error rates for sequential circuits for particles with low LET values due to temporal masking. SEU-hardened FFs benefit less from temporal masking than conventional FFs. Circuit hardening implications for SEU-hardened and unhardened FFs are discussed.

  5. Computational method to estimate Single Event Upset rates in an accelerator environment

    NASA Astrophysics Data System (ADS)

    Huhtinen, M.; Faccio, F.

    2000-08-01

    We present a new method to estimate Single Event Upsets (SEU) in a hadron accelerator environment, which is characterized by a complicated radiation spectrum. Our method is based on first principles, i.e. an explicit generation and transport of nuclear fragments and detailed accounting for energy loss by ionization. However, instead of simulating also the behaviour of the circuit, we use a Weibull fit to experimental heavy-ion SEU data in order to quantify the SEU sensitivity of the circuit. Thus, in principle, we do not need to know details about the circuit and our method is almost free of adjustable parameters - we only need a reasonable guess for the Sensitive Volume (SV) size. We show by a comparison with experimental data that our method predicts the SEU cross sections for protons rather accurately. We then indicate with an example how our method could be applied to predict SEU rates at the forthcoming LHC experiments.

  6. Evaluating system for SRAM-based FPGA single event upset rate

    2016-09-01

    This paper takes static random-access-memory (SRAM)-based field-programmable-gate-array (FPGA) as the research object. Attention is focused on the configuration memory of this kind of FPGA, and the research has been devoted to the contents of the configuration memory and the configuration circuit to manage its contents. The single event upset (SEU) happening in the configuration memory doesn't lead to a functional failure necessarily. The dynamic SEU is SEU which happens in the configuration memory and causes necessarily function failure. This paper introduces a test method of dynamic SUE rate for the SRAM-based FPGA by designing a FPGA with self-test function.

  7. Variation in proton-induced upsets rates from large solar flares using an improved SEU model

    Proton integral flux measurements during solar energetic particle (SEP) events, from the CPME instrument onboard the IMP-8 satellite, and the proton detector on the GOES-7 satellite, are utilized to calculate proton-induced single-event upset (SEU). An improved two-parameter SEU cross section model is used for three RAM devices. The log of the 239 actual RAM upsets on the TDRS-1 satellite during the October 19, 1989 SEP event allowed a comparison between the recorded number of upsets/chip per day and those predicted based on the GOES-7 data, the two-parameter model, and the shielding distribution curve.

    This paper implements the study on the Dose Rate Upset effect of PDSOI SRAM (Partially Depleted Silicon-On-Insulator Static Random Access Memory) with the Qiangguang-I accelerator in Northwest Institute of Nuclear Technology. The SRAM (Static Random Access Memory) chips are developed by the Institute of Microelectronics of Chinese Academy of Sciences. It uses the full address test mode to determine the upset mechanisms. A specified address test is taken in the same time. The test results indicate that the upset threshold of the PDSOI SRAM is about 1×108 Gy(Si)/s. However, there are a few bits upset when the dose rate reaches up to 1.58 × 109 Gy(Si)/s. The SRAM circuit can still work after the high level γ ray pulse. Finally, the upset mechanism is determined to be the rail span collapse by comparing the critical charge with the collected charge after γ ray pulse. The physical locations of upset cells are plotted in the layout of the SRAM to investigate the layout defect. Then, some layout optimizations are made to improve the dose rate hardened performance of the PDSOI SRAM.

  9. Fault Tolerance Implementation within SRAM Based FPGA Designs based upon Single Event Upset Occurrence Rates

    2006-01-01

    Emerging technology is enabling the design community to consistently expand the amount of functionality that can be implemented within Integrated Circuits (ICs). As the number of gates placed within an FPGA increases, the complexity of the design can grow exponentially. Consequently, the ability to create reliable circuits has become an incredibly difficult task. In order to ease the complexity of design completion, the commercial design community has developed a very rigid (but effective) design methodology based on synchronous circuit techniques. In order to create faster, smaller and lower power circuits, transistor geometries and core voltages have decreased. In environments that contain ionizing energy, such a combination will increase the probability of Single Event Upsets (SEUs) and will consequently affect the state space of a circuit. In order to combat the effects of radiation, the aerospace community has developed several "Hardened by Design" (fault tolerant) design schemes. This paper will address design mitigation schemes targeted for SRAM Based FPGA CMOS devices. Because some mitigation schemes may be over zealous (too much power, area, complexity, etc.. . .), the designer should be conscious that system requirements can ease the amount of mitigation necessary for acceptable operation. Therefore, various degrees of Fault Tolerance will be demonstrated along with an analysis of its effectiveness.

    International travellers are at a risk of infectious diseases not seen in their home country. Stomach upsets are common in travellers, including on cruise ships. This study compares the incidence of stomach upsets on land- and cruise-based holidays. A major British tour operator has administered a Customer Satisfaction Questionnaire (CSQ) to UK resident travellers aged 16 or more on return flights from their holiday abroad over many years. Data extracted from the CSQ was used to measure self-reported stomach upset in returning travellers. From summer 2000 through winter 2008, 6,863,092 questionnaires were completed; 6.6% were from cruise passengers. A higher percentage of land-based holiday-makers (7.2%) reported stomach upset in comparison to 4.8% of cruise passengers (RR = 1.5, p<0.0005). Reported stomach upset on cruises declined over the study period (7.1% in 2000 to 3.1% in 2008, p<0.0005). Over 25% of travellers on land-based holidays to Egypt and the Dominican Republic reported stomach upset. In comparison, the highest proportion of stomach upset in cruise ship travellers were reported following cruises departing from Egypt (14.8%) and Turkey (8.8%). In this large study of self-reported illness both demographic and holiday choice factors were shown to play a part in determining the likelihood of developing stomach upset while abroad. There is a lower cumulative incidence and declining rates of stomach upset in cruise passengers which suggest that the cruise industry has adopted operations (e.g. hygiene standards) that have reduced illness over recent years.

    Data from military/experimental flights and laboratory testing indicate that typical non radiation-hardened 64K and 256K static random access memories (SRAMs) can experience a significant soft upset rate at aircraft altitudes due to energetic neutrons created by cosmic ray interactions in the atmosphere. It is suggested that error detection and correction (EDAC) circuitry be considered for all avionics designs containing large amounts of semi-conductor memory.

    Useful process modeling of upset welding requires contributions from metallurgy, welding engineering, thermal analysis and experimental mechanics. In this report, the significant milestones for such an effort are outlined and probable difficult areas are pointed out. Progress to date is summarized and directions for future research are offered. With regard to the computational aspects of this problem, a 2-D heat conduction computer code has been modified to incorporate electrical heating, and computations have been run for an axisymmetric problem with simple viscous material laws and d.c. electrical boundary conditions. In the experimental endeavor, the boundary conditions have been measured during the welding process, although interpretation of voltage drop measurements is not straightforward. The ranges of strain, strain rate and temperature encountered during upset welding have been measured or calculated, and the need for a unifying constitutive law is described. Finally, the possible complications of microstructure and interfaces are clarified.

    Airplane upset accidents are a leading factor in hull losses and fatalities. This study compared five types of airplane-upset training. Each group was composed of eight, non-military pilots flying in their probationary year for airlines operating in the United States. The first group, 'No aero / no upset,' was made up of pilots without any airplane upset training or aerobatic flight experience; the second group, 'Aero/no upset,' of pilots without any airplane-upset training but with aerobatic experience; the third group, 'No aero/upset,' of pilots who had received airplane-upset training in both ground school and in the simulator; the fourth group, 'Aero/upset,' received the same training as Group Three but in addition had aerobatic flight experience; and the fifth group, 'In-flight' received in-flight airplane upset training using an instrumented in-flight simulator. Recovery performance indicated that clearly training works - specifically, all 40 pilots recovered from the windshear upset. However few pilots were trained or understood the use of bank to change the direction of the lift vector to recover from nose high upsets. Further, very few thought of, or used differential thrust to recover from rudder or aileron induced roll upsets. In addition, recovery from icing-induced stalls was inadequate.

    An improved state-space analysis of the CMOS static RAM cell is presented. Introducing theconcept of the dividing line, the critical charge for heavy-ion-induced upset of memory cells can becalculated considering symmetrical as well as asymmetrical capacitive loads. From the criticalcharge, the upset-rate per bit-day for static RAMs can be estimated.

    Research Into Action, Inc. and the Sacramento Municipal Utility District (SMUD) worked together to conduct research on the behaviors and energy use patterns of SMUD residential customers who voluntarily signed on to a Time-of-Use rate pilot launched under the PowerChoice label. The project was designed to consider the how and why of residential customers ability and willingness to engage in demand reduction behaviors, and to link social and behavioral factors to observed changes in demand. The research drew on a combination of load interval data and three successive surveys of participating households. Two experimental treatments were applied to test the effects of increased information on households ability to respond to the Time-of-Use rates. Survey results indicated that participants understood the purpose of the Time-of-Use rate and undertook substantial appropriate actions to shift load and conserve. Statistical tests revealed minor initial price effects and more marked, but still modest, adjustments to seasonal rate changes. Tests of the two information interventions indicated that neither made much difference to consumption patterns. Despite the lackluster statistical evidence for load shifting, the analysis points to key issues for critical analysis and development of residential Time-of-Use rates, especially pertinent as California sets the stage for demand response in more California residences.

  17. An analytical method for predicting CMOS SRAM upsets with application to asymmetrical memory cells

    Buehler, Martin G.; Allen, Richard A.

    1986-01-01

    An analytical method was developed to predict the heavy-ion-induced upset rate of static random access memory (SRAM) cells. The method was applied to the design of a memory with asymmetrical cells where the goal was to increase the upset rate in order to increase the number of observed upsets in a space environment. The asymmetry is achieved by increasing the drain area of selected transistors in the cell. Results from the analytical model for a space environment indicate the upset rate for the experimental asymmetrical cell (17.2 upsets/1 kbit-year) will be 4.7 times larger than the upset rate for the minimum-geometry balanced cell (3.6 upsets/1 kbit-year). The asymmetrical SRAM was designed into a test chip intended for the Combined Release and Radiation Effects Satellite (CRRES).

    Recognizing that innovation and good public policy do not always proclaim themselves, Synapse Energy Economics and the Regulatory Assistance Project, under a contract with the California Energy Commission (CEC) and the National Renewable Energy Laboratory (NREL), undertook a survey of state policies on rates for partial-requirements customers with onsite distributed generation. The survey investigated a dozen or so states. These varied in geography and the structures of their electric industries. By reviewing regulatory proceedings, tariffs, publications, and interviews, the researchers identified a number of approaches to standby and associated rates--many promising but some that are perhaps not--that deserve policymakers' attention if they are to promote the deployment of cost-effective DG in their states.

    A simulation program for predicting dose rate upset has been adapted from the Power Analysis for Integrated Circuits program (PANIC). The program provides detailed analysis on the V/sub CC/V/sub SS/ difference at any location within the array as well as the amount of photocurrent being collected, as a function of design. The simulation has been compared to experiment for a specific design and was found to correlate to within 20% at 5 volts.

  1. Estimation of customer lifetime value of a health insurance with interest rates obeying uniform distribution

    NASA Astrophysics Data System (ADS)

    2015-12-01

    Nowadays some firms, including insurer firms, think that customer-centric services are better than product-centric ones in terms of marketing. Insurance firms will try to attract as many new customer as possible while maintaining existing customer. This causes the Customer Lifetime Value (CLV) becomes a very important thing. CLV are able to put customer into different segments and calculate the present value of a firm's relationship with its customer. Insurance customer will depend on the last service he or she can get. So if the service is bad now, then customer will not renew his contract though the service is very good at an erlier time. Because of this situation one suitable mathematical model for modeling customer's relationships and calculating their lifetime value is Markov Chain. In addition, the advantages of using Markov Chain Modeling is its high degree of flexibility. In 2000, Pfeifer and Carraway states that Markov Chain Modeling can be used for customer retention situation. In this situation, Markov Chain Modeling requires only two states, which are present customer and former ones. This paper calculates customer lifetime value in an insurance firm with two distinctive interest rates; the constant interest rate and uniform distribution of interest rates. The result shows that loyal customer and the customer who increase their contract value have the highest CLV.

    The Proton Upset Monte Carlo Simulation (PROPSET) program calculates the frequency of on-orbit upsets in computer chips (for given orbits such as Low Earth Orbit, Lunar Orbit, and the like) from proton bombardment based on the results of heavy ion testing alone. The software simulates the bombardment of modern microelectronic components (computer chips) with high-energy (.200 MeV) protons. The nuclear interaction of the proton with the silicon of the chip is modeled and nuclear fragments from this interaction are tracked using Monte Carlo techniques to produce statistically accurate predictions.

  3. Tradeoffs in Flight Design Upset Mitigation in State of the Art FPGAs: Hardened by Design vs. Design Level Hardening

    NASA Technical Reports Server (NTRS)

    Swift, Gary M.; Roosta, Ramin

    2004-01-01

    This presentation compares and contrasts the effectiveness and the system/designer impacts of the two main approaches to upset hardening: the Actel approach (RTSX-S and RTAX-S) of low-level (inside each flip-flop) triplication and the Xilinx approach (Virtex and Virtex2) of design-level triplication of both functional blocks and voters. The effectiveness of these approaches is compared using measurements made in conjunction with each of the FPGAs' manufacturer: for Actel, published data [1] and for Xilinx, recent results from the Xilinx SEE Test Consortium (note that the author is an active and founding member). The impacts involve Actel advantages in the areas of transistor-utilization efficiency and minimizing designer involvement in the triplication while the Xilinx advantages relate to the ability to custom tailor upset hardness and the flexibility of re-configurability. Additionally, there are currently clear Xilinx advantages in available features such as the number of I/O's, logic cells, and RAM blocks as well as speed. However, the advantage of the Actel anti-fuses for configuration over the Xilinx SRAM cells is that the latter need additional functionality and external circuitry (PROMs and, at least a watchdog timer) for configuration and configuration scrubbing. Further, although effectively mitigated if done correctly, the proton upset-ability of the Xilinx FPGAs is a concern in severe proton-rich environments. Ultimately, both manufacturers' upset hardening is limited by SEFI (single-event functional interrupt) rates where it appears the Actel results are better although the Xilinx Virtex2-family result of about one SEFI in 65 device-years in solar-min GCR (the more intense part of the galactic cosmic-ray background) should be acceptable to most missions

    2015-09-01

    With rapid growth in energy efficiency and distributed generation, electric utilities are anticipating stagnant or decreasing electricity sales, particularly in the residential sector. Utilities are increasingly considering alternative rates structures that are designed to recover fixed costs from residential solar photovoltaic (PV) customers with low net electricity consumption. Proposed structures have included fixed charge increases, minimum bills, and increasingly, demand rates - for net metered customers and all customers. This study examines the electricity bill implications of various residential rate alternatives for multiple locations within the United States. For the locations analyzed, the results suggest that residential PV customers offset, on average, between 60% and 99% of their annual load. However, roughly 65% of a typical customer's electricity demand is non-coincidental with PV generation, so the typical PV customer is generally highly reliant on the grid for pooling services.

    1989-12-01

    The regulatory community believes that there is far more economic potential for demand-side management and efficiency improvements than is currently envisioned and being pursued by utilities. A system of rewards for utility efficiency investments includes elements of customer equity, lost-revenue recovery, and an exponential incentive return for shareholders. To encourage greater utility investment in energy efficiency, we may need to make the profit on a kilowatt-hour saved equal or greater than profit on a kilowatt-hour consumed. This article focuses on a three-part proposal devised to encourage utilities to channel capital into lower cost efficiency investments. 4 tabs.

  11. Heavy Ion Irradiation Fluence Dependence for Single-Event Upsets in a NAND Flash Memory

    Chen, Dakai; Wilcox, Edward; Ladbury, Raymond L.; Kim, Hak; Phan, Anthony; Seidleck, Christina; Label, Kenneth

    2016-01-01

    We investigated the single-event effect (SEE) susceptibility of the Micron 16 nm NAND flash, and found that the single-event upset (SEU) cross section varied inversely with cumulative fluence. We attribute the effect to the variable upset sensitivities of the memory cells. Furthermore, the effect impacts only single cell upsets in general. The rate of multiple-bit upsets remained relatively constant with fluence. The current test standards and procedures assume that SEU follow a Poisson process and do not take into account the variability in the error rate with fluence. Therefore, traditional SEE testing techniques may underestimate the on-orbit event rate for a device with variable upset sensitivity.

  15. Heavy Ion Irradiation Fluence Dependence for Single-Event Upsets of NAND Flash Memory

    We investigated the single-event effect (SEE) susceptibility of the Micron 16 nm NAND flash, and found the single-event upset (SEU) cross section varied inversely with fluence. The SEU cross section decreased with increasing fluence. We attribute the effect to the variable upset sensitivities of the memory cells. The current test standards and procedures assume that SEU follow a Poisson process and do not take into account the variability in the error rate with fluence. Therefore, heavy ion irradiation of devices with variable upset sensitivity distribution using typical fluence levels may underestimate the cross section and on-orbit event rate.

    A method for predicting the SEU susceptibility of a standard-cell D-latch using an alpha-particle sensitive SRAM, SPICE critical charge simulation results, and alpha-particle interaction physics. A technique utilizing test structures to quickly and inexpensively characterize the SEU sensitivity of standard cell latches intended for use in a space environment. This bench-level approach utilizes alpha particles to induce upsets in a low LET sensitive 4-k bit test SRAM. This SRAM consists of cells that employ an offset voltage to adjust their upset sensitivity and an enlarged sensitive drain junction to enhance the cell's upset rate.

    Mason, G. M.

    1983-01-01

    Essential factors for the design of transient upset monitors for computers are discussed. The upset is a system level event that is software dependent. It can occur in the program flow, the opcode set, the opcode address domain, the read address domain, and the write address domain. Most upsets are in the program flow. It is shown that simple, external monitors functioning transparently relative to the system operations can be built if a detailed accounting is made of the characteristics of the faults that can happen. Sample applications are provided for different states of the Z-80 and 8085 based system.

  2. Process Upsets Involving Trace Contaminant Control Systems

    NASA Technical Reports Server (NTRS)

    Graf, John C.; Perry, Jay; Wright, John; Bahr, Jim

    2000-01-01

    Paradoxically, trace contaminant control systems that suffer unexpected upsets and malfunctions can release hazardous gaseous contaminants into a spacecraft cabin atmosphere causing potentially serious toxicological problems. Trace contaminant control systems designed for spaceflight typically employ a combination of adsorption beds and catalytic oxidation reactors to remove organic and inorganic trace contaminants from the cabin atmosphere. Interestingly, the same design features and attributes which make these systems so effective for purifying a spacecraft's atmosphere can also make them susceptible to system upsets. Cabin conditions can be contributing causes of phenomena such as adsorbent "rollover" and catalyst poisoning can alter a systems performance and in some in stances release contamination into the cabin. Evidence of these phenomena has been observed both in flight and during ground-based tests. The following discussion describes specific instances of system upsets found in trace contaminant control systems, groups these specific upsets into general hazard classifications, and recommends ways to minimize these hazards.

  3. System-level analysis of single event upset susceptibility in RRAM architectures

    NASA Astrophysics Data System (ADS)

    Liu, Rui; Barnaby, Hugh J.; Yu, Shimeng

    2016-12-01

    In this work, the single event upset susceptibility of a resistive random access memory (RRAM) system with 1-transistor-1-resistor (1T1R) and crossbar architectures to heavy ion strikes is investigated from the circuit-level to the system-level. From a circuit-level perspective, the 1T1R is only susceptible to single-bit-upset (SBU) due to the isolation of cells, while in the crossbar, multiple-bit-upsets may occur because ion-induced voltage spikes generated on drivers may propagate along rows or columns. Three factors are considered to evaluate system-level susceptibility: the upset rate, the sensitive area, and the vulnerable time window. Our analysis indicates that the crossbar architecture has a smaller maximum bit-error-rate per day as compared to the 1T1R architecture for a given sub-array size, I/O width and susceptible time window.

Upsets were observed in both technology nodes when the SRAM was operated in a low power state. The experimental cross section depends strongly on both bias and technology node feature size, consistent with previous work in which SRAMs were irradiated with low energy muons and protons.

  6. RH1020 Single Event Clock Upset Summary Report

    NASA Technical Reports Server (NTRS)

    Katz, Richard B.; Wang, J. J.

    1998-01-01

    This report summarizes the testing and analysis of "single event clock upset' in the RH1020. Also included are SEU-rate predictions and design recommendations for risk analysis and reduction. The subject of "upsets" in the RH1020 is best understood by using a model consisting of a global clock buffer and a D-type flip-flop as the basic memory unit. The RH1020 is built on the ACT 1 family architecture. As such, it has one low-skew global clock buffer with a TTL-level input threshold that is accessed via a single dedicated pin. The clock signal is driven to full CMOS levels, buffered, and sent to individual row buffers with one buffer per channel. For low-skew performance, the outputs of all of the RH1020 row buffers are shorted together via metal lines, as is done in the A1020B. All storage in the RH1020 consists of routed flip-flops, constructed with multiplexors and feedback through the routing segments. A simple latch can be constructed from a single (combinatorial or C) module; an edge-triggered flip-flop is constructed using two concatenated latches. There is no storage in the I/O modules. The front end of the clock buffering circuitry, at a common point relative to the row buffer, is a sub-circuit that was determined to be the most susceptible to heavy ions. This is due, in part, to its smaller transistors compared to the rest of the circuitry. This conclusion is also supported by SPICE simulations and an analysis of the heavy ion data, described in this report. The edge triggered D flip-flop has two single-event-upset modes. Mode one, called C-module upset, is caused by a heavy ion striking the C-module's sensitive area on the silicon and produces a soft single bit error at the output of the flip-flop. Mode two, called clock upset, is caused by a heavy ion strike on the clock buffer, generating a runt pulse interpreted as a false clock signal and consequently producing errors at the flip-flop outputs. C-module upset sensitivity in the RH1020 is essentially

    Distribution of radiation dose was measured by customizing an autonomous cleaning robot "Roomba" and a scintillation counter. The robot was used as a vehicle carrying the scintillation survey meter, and was additionally equipped with an H8 micro computer to remote-control the vehicle and to send measured data. The data obtained were arranged with position data, and then the distribution map of the radiation dose rate was produced. Manual, programmed and autonomous driving tests were conducted, and all performances were verified. That is, for each operational mode, the measurements both with moving and with discrete moving were tried in and outside of a room. Consequently, it has been confirmed that remote sensing of radiation dose rate is possible by customizing a robot on market.

  8. Analysis of vortex wake encounter upsets

    The problem of an airplane being upset by encountering the vortex wake of a large transport on takeoff or landing is currently receiving considerable attention. This report describes the technique and results of a study to assess the effectiveness of automatic control systems in alleviating vortex wake upsets. A six-degree-of-freedom nonlinear digital simulation was used for this purpose. The analysis included establishing the disturbance input due to penetrating a vortex wake from an arbitrary position and angle. Simulations were computed for both a general aviation airplane and a commercial jet transport. Dynamic responses were obtained for the penetrating aircraft with no augmentation, and with various command augmentation systems, as well as with human pilot control. The results of this preliminary study indicate that attitude command augmentation systems can provide significant alleviation of vortex wake upsets; and can do it better than a human pilot.

    To report the technical aspects of customized high-dose-rate brachytherapy for vaginal rhabdomyosarcoma using MRI- and CT-based planning in a 20-month-old girl. An impression of the vaginal cavity at the resection site was taken after adequate lubrication of the vagina with lidocaine jelly. The impression was processed in the dental laboratory to obtain an MRI-compatible device with three imbedded catheters 0.4 mm apart, assuring tumor coverage. An MRI- and CT-based simulation under anesthesia with the applicator in place were performed, and the images were registered for contouring and planning to deliver 40 Gy in 10 fractions daily. Dose to the ovaries was limited to a mean dose less than 4 Gy. Treatment was delivered daily under anesthesia with no acute complications. Brachytherapy using a customized applicator has many advantages over prefabricated vaginal cylinders for young girls. It allows greater dose distribution conformality with the possibility of contralateral vaginal wall sparing and more reproducible daily positioning. MRI-based planning is mainly performed to facilitate delineation of the target volume and the ovaries, which are easily identified on MRI. The customized applicator offers many advantages of which treatment reproducibility, inherent MRI compatibility, and excellent dose distribution conformality. Our brachytherapy technique using MRI and CT scan planning allows precise tumor and normal tissues delineation resulting in excellent tumor coverage and normal tissues sparing.

  14. UpSet: Visualization of Intersecting Sets

    2016-01-01

    Understanding relationships between sets is an important analysis task that has received widespread attention in the visualization community. The major challenge in this context is the combinatorial explosion of the number of set intersections if the number of sets exceeds a trivial threshold. In this paper we introduce UpSet, a novel visualization technique for the quantitative analysis of sets, their intersections, and aggregates of intersections. UpSet is focused on creating task-driven aggregates, communicating the size and properties of aggregates and intersections, and a duality between the visualization of the elements in a dataset and their set membership. UpSet visualizes set intersections in a matrix layout and introduces aggregates based on groupings and queries. The matrix layout enables the effective representation of associated data, such as the number of elements in the aggregates and intersections, as well as additional summary statistics derived from subset or element attributes. Sorting according to various measures enables a task-driven analysis of relevant intersections and aggregates. The elements represented in the sets and their associated attributes are visualized in a separate view. Queries based on containment in specific intersections, aggregates or driven by attribute filters are propagated between both views. We also introduce several advanced visual encodings and interaction methods to overcome the problems of varying scales and to address scalability. UpSet is web-based and open source. We demonstrate its general utility in multiple use cases from various domains. PMID:26356912

  20. Mass Customization Production Planning System by Advance Demand Information Based on Unfulfilled-order-rate

    NASA Astrophysics Data System (ADS)

    Ueno, Nobuyuki; Kawasaki, Masaya; Okuhara, Koji

    In this paper, we try to model for ‘Naiji System’ which is a unique corporation between a maker and suppliers in Japan. We propose Mass Customization Production Planning & Management System (MCPS) based on unfulfilled-order-rate by using Advance Demand Information, which is called ‘Naiji’. This model is formulated as a nonlinear stochastic programming problem which minimizes the sum of production cost and inventory holding cost subject to the set of probabilistic constraint and some linear production constraints. We propose the new upper bound SOn (ρmin) to estimate the unfulfilled-order-rate more strictly. The procedure to find a good solution is developed by solving the linear programming problem repeatedly on the basic solution strategy that is ‘relaxation’. A computational load to obtain a solution by the proposed indicator is shown to be very small. Finally, an availability of the procedure is shown.

  1. Rating Correlations Between Customs Codes and Export Control Lists: Assessing the Needs and Challenges

    Chatelus, Renaud; Heine, Pete

    2016-01-01

    Correlation tables are the linchpins between the customs codes used to classify commodities in international trade and the control lists used for strategic trade control (STC) purposes. While understanding the customs classification system can help the STC community better understand strategic trade flows, better identify which trade operations require permits, and more effectively detect illegal exports, the two systems are different in scope, philosophy, content, and objectives. Many indications point to the limitations of these correlation tables, and it is important to understand the nature of the limitations and the complex underlying reasons to conceive possible improvements. As part of its Strategic Trade and Supply Chain Analytics Initiative, Argonne National Laboratory supported a study of a subset of the European Union’s TARIC correlation table. The study included development of a methodology and an approach to rating the quality and relevance of individual correlations. The study was intended as a first step to engage the STC community in deflections and initiatives to improve the conception and use of correlations, and its conclusions illustrate the scope and complex nature of the challenges to overcome. This paper presents the two classification systems, analyzes the needs for correlation tables and the complex challenges associated with them, summarizes key findings, and proposes possible ways forward.

    1997-02-10

    The filtration/absorption process, coupled with optimum treatments, prevent facility upsets that increase the time and resources required for bringing a well back on-line following an acid stimulation. Surface active agents, required in acidizing to improve well productivity, can form oil/water emulsions and cause unacceptable oil and grease levels during acid flowback. But recent offshore experiences after acidizing show that operators can achieve oil and grease discharge limits without facility upsets. To minimize oil and grease, the additives need to be optimized by adding a mutual breakout solvent (MBS). MBS has the dual function of being a mutual solvent and a sludge and emulsion control additive. The paper discusses acidizing problems, acid additives, handling options, and a case history of the Main Pass A field.

    Solid-state resistance upset welding has been successfully applied to fabrication of small vessels. The process has advantages compared with the fusion welding processes currently used to join the two halves of such vessels. These advantages result from the improved metallurgical properties of the weld zone and the simplicity of the welding process. Spherical and cylindrical shapes have been fabricated using the upset welding process. Nondestructive and destructive tests have shown excellent weld strength. Storage tests have demonstrated long term compatibility of the welds for cylindrical parts made from 304L stainless steel that have been in storage for eight years. Spherical vessels and reinforced desip vessels made from forged 21-6-9 stainless steel have been prepared for storage.

    In the previous paper, we proposed Mass Customization Production Planning & Management System (MCPS) based on unfulfilled-order-rate by using Advance Demand Information which is called ‘Naiji System’ as an unique corporation between a maker and suppliers in Japan, and 3 indicators to estimate the unfulfilled-order-rate. Applying these indicators to the model, we investigated the behavior of unfulfilled-order-rate at the final period in the planning horizon. In this paper, we propose a new model for purchasing, and investigate the unfulfilled-order-rate at each period and the impact to the total inventory. We find that the total inventories become 5.9%-20.0% decreases by using SOn rather than by using SOn(0). And we enhance a base-stock policy to a new one with multi-period. We prove that the MCPS model for purchasing by using SOn(0) is equivalent to the base-stock policy with multi-period under the specified condition. Under this condition, the proposed model by using SOn decreases inventories more than the base-stock policy with multi-period.

    Trained sensory panel ratings and Warner-Bratzler shear force (WBS) values from the Beef Customer Satisfaction study are reported. Carcasses were chosen to fit into USDA quality grades of Top Choice (upper two-thirds of USDA Choice), Low Choice, High Select, and Low Select. A trained, descriptive attribute panel evaluated top loin, top sirloin, and top round steaks for muscle fiber tenderness, connective tissue amount, overall tenderness, juiciness, flavor intensity, cooked beef flavor intensity, and cooked beef fat flavor intensity. Four steaks from each of the three cuts from each carcass were assigned randomly to one of four cooking endpoint temperature treatments (60, 65, 70, or 75 degrees C) for WBS determination. For all trained panel measures of tenderness and WBS, regardless of USDA quality grade, top loin steaks were rated higher than top sirloin steaks, which were rated higher than top round steaks (P < 0.05). There were significant interactions between USDA quality grade and cut for most of the trained sensory panel traits: USDA quality grade influenced ratings for top loin steaks more than ratings for top round steaks or top sirloin steaks. Three interactions were significant for WBS values: USDA quality grade x endpoint temperature (P = 0.02), USDA quality grade x cut (P = 0.0007), and cut x endpoint temperature (P = 0.0001). With the exception of High Select, WBS values increased (P < 0.05) for each grade with increasing endpoint temperature. Choice top loin and top round steaks had lower (P < 0.05) WBS values than Select steaks of the same cut; however, only Top Choice top sirloin steaks differed (P < 0.05) from the other USDA grades. As endpoint temperatures increased, WBS values for top sirloin steaks increased substantially compared to the other cuts. When cooked to 60 degrees C, top sirloin steaks were closer to top loin steaks in WBS values, when cooked to 75 degrees C, top sirloin steaks were closer to top round steaks in WBS values. Simple

    Agriculture remains one of the most hazardous occupations in the U.S. By conservative estimates, tractor overturns alone claim 120 lives annually. A rollover protective structure (ROPS) and a seatbelt are a highly effective engineering safety control that can prevent many of these fatalities and reduce the severity of injuries associated with tractor overturn. SAE J2194 is a consensus performance standard established for agricultural ROPS. According to this standard, satisfactory ROPS performance can be demonstrated through static testing, field upset testing, or impact testing. A previous modeling study suggested that static testing may underpredict the strain induced in a ROPS during afield upset. In the current study, field upset testing and laboratory static testing results were compared. Field upset testing included six rear and six side upset tests performed according to SAE J2194 guidelines. Additionally, static testing was performed on a ROPS of the same model. The results support findings from the modeling study. Near the lowest sections of the ROPS, the plastic strain resulting from rear upset testing exceeded the plastic strain from static testing for 18 of 24 data points. Conversely, the ROPS plastic strain from side upset testing was typically less than plastic strain from laboratory static testing. However, data indicate that the side upset test may not be very repeatable. This study suggests that the longitudinal loading energy criterion for static testing might not be a conservative predictor of rear upset ROPS response.

    Despite substantial growth in the service industry and emerging work on turnover consequences, little research examines how unit-level turnover rates affect essential customer-related outcomes. The authors propose an operational disruption framework to explain why voluntary turnover impairs customers' service quality perceptions. On the basis of a sample of 75 work units and data from 5,631 employee surveys, 59,602 customer surveys, and organizational records, results indicate that unit-level voluntary turnover rates are negatively related to service quality perceptions. The authors also examine potential boundary conditions related to the disruption framework. Of 3 moderators studied (group cohesiveness, group size, and newcomer concentration), results show that turnover's negative effects on service quality are more pronounced in larger units and in those with a greater concentration of newcomers.

    Climate not only influences the behavior of people in urban environments but also affects people's schedules and travel plans. Therefore, providing people with appropriate long-term climate evaluation information is crucial. Therefore, we developed an innovative climate assessment system based on field investigations conducted in three cities located in Northern, Central, and Southern Taiwan. The field investigations included the questionnaire surveys and climate data collection. We first analyzed the relationship between the participants and climate parameters comprising physiologically equivalent temperature, air temperature, humidity, wind speed, solar radiation, cloud cover, and precipitation. Second, we established the neutral value, comfort range, and dissatisfied range of each parameter. Third, after verifying that the subjects' perception toward the climate parameters vary based on individual preferences, we developed the customized rating assessment of climate suitability (CRACS) approach, which featured functions such as personalized and default climate suitability information to be used by users exhibiting varying demands. Finally, we performed calculations using the climate conditions of two cities during the past 10 years to demonstrate the performance of the CRACS approach. The results can be used as a reference when planning activities in the city or when organizing future travel plans. The flexibility of the assessment system enables it to be adjusted for varying regions and usage characteristics.

    Net metering has become a widespread mechanism in the U.S. for supporting customer adoption of distributed photovoltaics (PV), but has faced challenges as PV installations grow to a larger share of generation in a number of states. This paper examines the value of the bill savings that customers receive under net metering, and the associated role of retail rate design, based on a sample of approximately two hundred residential customers of California's two largest electric utilities. We find that the bill savings per kWh of PV electricity generated varies by more than a factor of four across the customers in the sample, which is largely attributable to the inclining block structure of the utilities' residential retail rates. We also compare the bill savings under net metering to that received under three potential alternative compensation mechanisms, based on California's Market Price Referent (MPR). We find that net metering provides significantly greater bill savings than a full MPR-based feed-in tariff, but only modestly greater savings than alternative mechanisms under which hourly or monthly net excess generation is compensated at the MPR rate.

    Background: Today, the challenges of quality improvement and customer focus as well as systems development are important and inevitable matters in higher education institutes. There are some highly competitive challenges among educational institutes, including accountability to social needs, increasing costs of education, diversity in educational methods and centers and their consequent increasing competition, and the need for adaptation of new information and knowledge to focus on students as the main customers. Hence, the purpose of this study was to determine the rate of costumer focus based on Isfahan University of Medical Sciences students’ viewpoints and to suggest solutions to improve this rate. Materials and Methods: This was a cross-sectional study carried out in 2011. The statistical population included all the students of seven faculties of Isfahan University of Medical Sciences. According to statistical formulae, the sample size consisted of 384 subjects. Data collection tools included researcher-made questionnaire whose reliability was found to be 87% by Cronbach's alpha coefficient. Finally, using the SPSS statistical software and statistical methods of independent t-test and one-way analysis of variance (ANOVA), Likert scale based data were analyzed. Results: The mean of overall score for customer focus (student-centered) of Isfahan University of Medical Sciences was 46.54. Finally, there was a relation between the mean of overall score for customer focus and gender, educational levels, and students’ faculties. Researcher suggest more investigation between Medical University and others. Conclusion: It is a difference between medical sciences universities and others regarding the customer focus area, since students’ gender must be considered as an effective factor in giving healthcare services quality. In order to improve the customer focus, it is essential to take facilities, field of study, faculties, and syllabus into consideration. PMID

    Net metering has become a widespread policy in the U.S. for supporting distributed photovoltaics (PV) adoption. Though specific design details vary, net metering allows customers with PV to reduce their electric bills by offsetting their consumption with PV generation, independent of the timing of the generation relative to consumption - in effect, compensating the PV generation at retail electricity rates (Rose et al. 2009). While net metering has played an important role in jump-starting the residential PV market in the U.S., challenges to net metering policies have emerged in a number of states and contexts, and alternative compensation methods are under consideration. Moreover, one inherent feature of net metering is that the value of the utility bill savings it provides to customers with PV depends heavily on the structure of the underlying retail electricity rate, as well as on the characteristics of the customer and PV system. Consequently, the value of net metering - and the impact of moving to alternative compensation mechanisms - can vary substantially from one customer to the next. For these reasons, it is important for policymakers and others that seek to support the development of distributed PV to understand both how the bill savings varies under net metering, and how the bill savings under net metering compares to other possible compensation mechanisms. To advance this understanding, we analyze the bill savings from PV for residential customers of California's two largest electric utilities, Pacific Gas and Electric (PG&E) and Southern California Edison (SCE). The analysis is based on hourly load data from a sample of 215 residential customers located in the service territories of the two utilities, matched with simulated hourly PV production for the same time period based on data from the nearest of 73 weather stations in the state.

    A general procedure for upset detection in complex systems, called the data block capture and analysis upset monitoring process is described and analyzed. The process consists of repeatedly recording a fixed amount of data from a set of predetermined observation lines of the system being monitored (i.e., capturing a block of data), and then analyzing the captured block in an attempt to determine whether the system is functioning correctly. The algorithm which analyzes the data blocks can be characterized in terms of the amount of time it requires to examine a given length data block to ascertain the existence of features/conditions that have been predetermined to characterize the upset-free behavior of the system. The performance of linear, quadratic, and logarithmic data analysis algorithms is rigorously characterized in terms of three performance measures: (1) the probability of correctly detecting an upset; (2) the expected number of false alarms; and (3) the expected latency in detecting upsets.

    Customer service initiatives in healthcare have become a popular way of attempting to improve patient satisfaction. This study investigates the effect of clinically focused customer service training on patient satisfaction in the setting of a 62,000-visit emergency department and level I trauma center. Analysis of patient complaints, patient compliments, and a statistically verified patient-satisfaction survey indicate that (1) all 14 key quality characteristics identified in the survey increased dramatically in the study period; (2) patient complaints decreased by over 70 percent from 2.6 per 1,000 emergency department (ED) visits to 0.6 per 1,000 ED visits following customer service training; and (3) patient compliments increased more than 100 percent from 1.1 per 1,000 ED visits to 2.3 per 1,000 ED visits. The most dramatic improvement in the patient satisfaction survey came in ratings of skill of the emergency physician, likelihood of returning, skill of the emergency department nurse, and overall satisfaction. These results show that clinically focused customer service training improves patient satisfaction and ratings of physician and nurse skill. They also suggest that such training may offer a substantial competitive market advantage, as well as improve the patients' perception of quality and outcome.

  2. Angular and Energy Dependence of Proton Upset in Optocouplers

    Proton upset effects in optocouplers were reported by LaBel, et al. that showed an unexpected increase in cross section for incident angles above 80 degrees. Although it appeared that the angular dependence was related to direct ionization from protons, the angular dependence was weaker than expected from basic geometrical arguments using a shallow charge collection depth. Later work showed that the angular dependence of proton upset observed in the earlier studies at a single energy could be explained by considering the distribution of proton recoil energies along with the assumption of a deeper charge collection depth, which was consistent with upset tests from heavy ions. However, an experimental test of the underlying assumptions in the latter work has yet to be done. Protons in space not only arrive over a wide range of incident angles, but also involve a distribution of proton energies. It is necessary to understand both the angular dependence and the dependence of proton upset on energy in order to determine how optocouplers will respond in space. If the angular dependence only occurs for extreme angles of incidence, it will have little impact on the overall cross section because of the narrow acceptance angle. The present work examines mechanisms for proton upset in optocouplers in more detail, investigating the energy dependence and the effects of different load conditions. A model for proton upset is developed, along with a laboratory screening method to determine whether direct ionization is significant for specific device types.

    For many decades, engineers and scientists have studied the effects of high power microwaves (HPM) on electronics. These studies usually focus on means of delivering energy to upset electronic equipment and ways to protect equipment from HPM. The motivation for these studies is to develop the knowledge necessary either to cause disruption or to protect electronics from disruption. Since electronic circuits must absorb sufficient energy to fail and the source used to deliver this energy is far away from the electronic circuit, the source must emit a large quantity of energy. In free space, for example, as the distance between the source and the target increases, the source energy must increase by the square of distance. The HPM community has dedicated substantial resources to the development of higher energy sources as a result. Recently, members of the HPM community suggested a new disruption mechanism that could potentially cause system disruptions at much lower energy levels. The new mechanism, based on nonlinear dynamics, requires an expanded theory of circuit operation. This report summarizes an investigation of electronic circuit nonlinear behavior as it applies to inductor-resistor-diode circuits (known as the Linsay circuit) and phased-locked-loops. With the improvement in computing power and the need to model circuit behavior with greater precision, the nonlinear effects of circuit has become very important. In addition, every integrated circuit has as part of its design a protective circuit. These protective circuits use some variation of semiconductor junctions that can interact with parasitic components, present in every real system. Hence, the protective circuit can behave as a Linsay circuit. Although the nonlinear behavior is understandable, it is difficult to model accurately. Many researchers have used classical diode models successfully to show nonlinear effects within predicted regions of operation. However, these models do not accurately predict

    Modern avionic systems for civil and military applications are becoming increasingly reliant upon embedded microprocessors and associated memory devices. The phenomenon of single event upset (SEU) is well known in space systems and designers have generally been careful to use SEU tolerant devices or to implement error detection and correction (EDAC) techniques where appropriate. In the past, avionics designers have had no reason to consider SEU effects but is clear that the more prevalent use of memory devices combined with increasing levels of IC integration will make SEU mitigation an important design consideration for future avionic systems. To this end, it is necessary to work towards producing models of the avionics SEU environment which will permit system designers to choose components and EDAC techniques which are based on predictions of SEU rates correct to much better than an order of magnitude. Measurements of the high latitude SEU environment at avionics altitude have been made on board a commercial airliner. Results are compared with models of primary and secondary cosmic rays and atmospheric neutrons. Ground based SEU tests of static RAMs are used to predict rates in flight.

    As part of NASA's Aviation Safety and Security Program, research has been in progress to develop aerodynamic modeling methods for simulations that accurately predict the flight dynamics characteristics of large transport airplanes in upset conditions. The motivation for this research stems from the recognition that simulation is a vital tool for addressing loss-of-control accidents, including applications to pilot training, accident reconstruction, and advanced control system analysis. The ultimate goal of this effort is to contribute to the reduction of the fatal accident rate due to loss-of-control. Research activities have involved accident analyses, wind tunnel testing, and piloted simulation. Results have shown that significant improvements in simulation fidelity for upset conditions, compared to current training simulations, can be achieved using state-of-the-art wind tunnel testing and aerodynamic modeling methods. This paper provides a summary of research completed to date and includes discussion on key technical results, lessons learned, and future research needs.

    In February 2016, the SuperKEKB positron-electron high-luminosity collider of the KEK laboratory (Tsukuba, Japan) started being commissioned. A dedicated commissioning detector, named BEAST2, has been used to characterize beam backgrounds before the Belle2 detector was rolled into the beams and to provide tuning parameters for Monte Carlo simulations. BEAST2 consists of a fiberglass support structure and several sub-detectors mounted onto it, including time projection chambers (TPCs) and He-3 tubes. In this work, we present direct measurements of radiation-induced single event upsets in a SRAM-based FPGA device installed in BEAST2 at a distance of ~ 1 m from the beam interaction point. Our goal was to provide experimental results of the expected radiation-induced configuration upset rate and power consumption variation at Belle2 and at other experiments operating in similar radiation environments. Beam currents for both electron and positron rings spanned a range between 50 and 500 mA, therefore providing data about the FPGA operation in different radiation conditions. Even if the machine has not been providing collisions yet, as the beams were not focused to the interaction point, our results show a rate of 0.15 upsets/day averaged over the whole commissioning time frame. We had neither evidence of total dose effects on the FPGA power consumption nor of permanent damage to the device.

    The aim of this study was to study the effects of overall well-being and well-being change on six supervisor-rated indicators of employee performance valued by organizations: overall performance, accountability, customer service, innovation, prosocial behavior, and self-development. The current study used two waves of well-being survey data collected over 2 years and supervisor performance ratings for 5691 employees. Ordinary least squares regression was conducted. Both well-being at baseline and two-year change in well-being were related to all six supervisor-rated performance dimensions, controlling for other employee characteristics. Overall well-being likely functioned as a resource enabling people to successfully perform across the specific areas highly valued by their company. Given this connection, well-being interventions could be used as a means to accomplish improved performance in dimensions that contribute to organizational performance.

    Only a small proportion of the published research on endocrine-disrupting chemicals (EDC) directly examined effects on neuroendocrine processes. There is an expanding body of evidence that anthropogenic chemicals exert effects on neuroendocrine systems and that these changes might impact peripheral organ systems and physiological processes. Neuroendocrine disruption extends the concept of endocrine disruption to include the full breadth of integrative physiology (i.e., more than hormones are upset). Pollutants may also disrupt numerous other neurochemical pathways to affect an animal's capacity to reproduce, develop and grow, or deal with stress and other challenges. Several examples are presented in this review, from both vertebrates and invertebrates, illustrating that diverse environmental pollutants including pharmaceuticals, organochlorine pesticides, and industrial contaminants have the potential to disrupt neuroendocrine control mechanisms. While most investigations on EDC are carried out with vertebrate models, an attempt is also made to highlight the importance of research on invertebrate neuroendocrine disruption. The neurophysiology of many invertebrates is well described and many of their neurotransmitters are similar or identical to those in vertebrates; therefore, lessons learned from one group of organisms may help us understand potential adverse effects in others. This review argues for the adoption of systems biology and integrative physiology to address the effects of EDC. Effects of pulp and paper mill effluents on fish reproduction are a good example of where relatively narrow hypothesis testing strategies (e.g., whether or not pollutants are sex steroid mimics) have only partially solved a major problem in environmental biology. It is clear that a global, integrative physiological approach, including improved understanding of neuroendocrine control mechanisms, is warranted to fully understand the impacts of pulp and paper mill effluents

    The occurrence of multiple upset errors during ground tests can contaminate the data and lead to error cross sections which are too high. In space, multiple errors may produce higher upsets than predicted and if they occur in single words they can defeat error detection and correction hardware. This investigation involves data which were taken during an experimental study of dose imprint effects in static memories. The results show that multiple errors occurred mainly for heavy ions with high linear energy transfers and with the majority of these in the soft upset sections of the dose-imprinted memory samples. The percentages of the total number of errors which were singles, doubles, and triplets, were determined as a function of LET, dose, and soft or hard section of the devices. The experimental observations are compared to the predictions of simple binomial statistics.

Conclusion that external reaction products cause no significant alteration of single-event-upset response based on comparison of data obtained from both lidded and unlidded devices and for proton beams impinging at angles ranging from 0 degrees to 180 degrees with respect to chip face. Study also found single-event-upset cross section increases only modestly as proton energy increased to 590 MeV, characteristic of maximum energies expected in belts of trapped protons surrounding Earth and Jupiter.

    The reported investigation shows that low-power TTL, standard TTL, low-power Schottky, and Schottky devices are all subject to upset by heavy ions. Low-power Schottky was the most sensitive of the device technologies tested. No evidence was found to correlate sensitivity to cosmic rays with any particular device manufacturer. The probability of upset of the logic devices is comparable to that of RAM's on a per-flip-flop basis, based on RAM data obtained by Kolasinski et al. (1979). The testing was performed by subjecting the devices to 120 MeV krypton ions from a cyclotron.

    Report cards currently published by the Centers for Medicare and Medicaid Services (CMS) offer composite (summary) quality measures based on a five-star ratings system, such as the one featured on the Nursing Home Compare website. These ratings are "one size fits all patients" measures. Nursing Home Compare Plus is an alternative that allows patients and their families to create their own composite scores based on their own preferences and medical needs. We present data from 146 patients who were discharged from the hospital to nursing homes who used Nursing Home Compare Plus. We found that the individual patient-constructed composites differed from CMS's five-star ratings composite. Patients differed from each other and from CMS in the number of performance measures they chose to include in their composite and in their weighting of each performance measure. When comparing Nursing Home Compare Plus to Medicare's five-star ratings, we found only minimal agreement on ranking of nursing homes. We conclude that patients might benefit if current report cards are modified to include an option for personalized ranking.

    2015-06-01

    Time-based rate programs1, enabled by utility investments in advanced metering infrastructure (AMI), are increasingly being considered by utilities as tools to reduce peak demand and enable customers to better manage consumption and costs. There are several customer systems that are relatively new to the marketplace and have the potential for improving the effectiveness of these programs, including in-home displays (IHDs), programmable communicating thermostats (PCTs), and web portals. Policy and decision makers are interested in more information about customer acceptance, retention, and response before moving forward with expanded deployments of AMI-enabled new rates and technologies. Under the Smart Grid Investment Grant Program (SGIG), the U.S. Department of Energy (DOE) partnered with several utilities to conduct consumer behavior studies (CBS). The goals involved applying randomized and controlled experimental designs for estimating customer responses more precisely and credibly to advance understanding of time-based rates and customer systems, and provide new information for improving program designs, implementation strategies, and evaluations. The intent was to produce more robust and credible analysis of impacts, costs, benefits, and lessons learned and assist utility and regulatory decision makers in evaluating investment opportunities involving time-based rates. To help achieve these goals, DOE developed technical guidelines to help the CBS utilities estimate customer acceptance, retention, and response more precisely.

    A simple gas collection apparatus based on the principles of a Torricelli tube has been designed and built to measure gas volume yields and flow rates. This instrument is routinely used to monitor and collect methane gas released during methane hydrate dissociation experiments. It is easily and inexpensively built, operates at ambient pressures and temperatures, and measures gas volumes of up to 7 L to a precision of about 15 ml (about 0.0025 mol). It is capable of measuring gas flow rates varying from more than 103 to less than 10-1 ml/min during gas evolution events that span minutes to several days. We have obtained a highly reproducible hydrate number of n=5.891 with a propagated uncertainty of ??0.020 for synthetic methane hydrate. ?? 2001 American Institute of Physics.

    Single-event upset effects from heavy ions were measured for Motorola silicon-on-insulator (SOI) microprocessor with 90 nm feature sizes at three frequencies of 500, 1066 and 1600 MHz. Frequency dependence of single-event upsets is discussed. The results of our studies suggest the single-event upset in registers and D-Cache tend to increase with frequency. This might have important implications for the overall single-event upset trend as technology moves toward higher frequencies.

    Parks, R.W.

    1983-01-01

    The first part of this study presents an econometric analysis of the consumer response to time-of-use pricing of electricity using data from the Wisconsin Residential Time-Of-Use Electricity Pricing Experiment for July of 1977. We employ a neoclassical consumer choice framework that assumes a two-stage consumer budgeting process. This framework, used also by Caves and Christensen and others in analyzing electricity demand, places emphasis on the estimation of substitution parameters in the context of conditional demand functions. We provide estimates of the elasticities of substitution which indicate how consumers adjust their consumption at various times in response to changes in the relative prices of electricity at these times. We distinguish a peak, off-peak, and two shoulder periods in our analysis. The results confirm for this multiperiod analysis the results of studies that examine only peak versus off-peak use in finding small but statistically significant substitution responses by consumers. The second part of the study considers measures of the welfare consequences for consumers of a shift to time differentiated rates. We show how the special structure of the choice model can be used to permit a simple calculation of a compensating variation measure of the welfare effects, and we present estimates of the measure for the various experimental groups based on the econometric results together with other evidence.

    2004-01-01

    A new model of single event upsets (SEUs), created in memory cells by heavy ions and high energy hadrons, has been developed. The model takes into account the spatial distribution of charge collection efficiency over the cell area not considered in previous approaches. Three-dimensional calculations made by the HADRON code have shown good agreement with experimental data for the energy dependence of proton SEU cross sections, sensitive depths and other SEU observables. The model is promising for prediction of SEU rates for memory chips exposed in space and in high-energy experiments as well as for the development of a high-energy neutron dosemeter based on the SEU effect.

    An in-home beef study evaluated consumer ratings from moderate-to-heavy beef users as influenced by cut (top loin, top sirloin, and top round steaks), USDA quality grade (Top Choice, Low Choice, High Select, and Low Select), and city (Chicago, Houston, Philadelphia, and San Francisco). Consumers (n = 2,212) evaluated each steak for overall like (OLIKE), tenderness (TEND), juiciness (JUIC), flavor desirability (DFLAV), and flavor intensity (IFLAV) using 23-point hedonic scales (23 = like extremely, extremely tender, extremely juicy, like extremely, and an extreme amount of flavor; 1 = dislike extremely, not at all tender, not at all juicy, dislike extremely, and no flavor at all). A USDA grade x cut interaction existed for OLIKE (P < .05). Consumers rated top loin steaks highest (P < .05) in OLIKE and ranked Top Choice highest of all steaks (P < .05). Within the top loin, consumers were not (P > .05) able to distinguish OLIKE differences between Low Choice and High Select or between High Select and Low Select. For OLIKE, top sirloin was rated intermediate (P < .05) of the three cuts, and consumers were not able to detect (P > .05) USDA quality grade differences. For OLIKE, top round was the lowest-rated (P < .05) cut. However, consumers preferred (OLIKE, P < .05) Top Choice to the other USDA grades offered. Grade and city interacted to affect TEND, JUIC, DFLAV, and IFLAV. The cut x city interaction was significant for all palatability attributes. Cut and city affected customer satisfaction more than USDA quality grade. Tenderness and flavor were important and equal contributors to OLIKE, r = .85 and r = .86, respectively.

    2004-07-01

    Anisotropic nanocomposite R-Fe-B/Fe magnets (R =Pr, Tb) were synthesized by hot pressing and subsequent die upsetting blends of R-rich and R-lean melt-spun ribbons. The magnets have a layered structure, in which alternating layers of the two starting alloys lay perpendicularly to the pressing direction. A crystallographic alignment of the R2Fe14B grains is observed in the R-rich layers, whose microstructure is identical to that of the conventional die-upset magnets. The R-lean layers consisting of exchange-coupled R2Fe14B and α-Fe grains retain the random crystallographic orientation. The obtained bulk R-lean magnets show better properties than magnets of the same overall composition prepared from a single alloy.

    2007-03-01

    Die-upset composite magnets fabricated from blends of melt-spun Nd-Fe-B ribbons and coarse (micron-size) soft magnetic powders (Fe, Fe-Co) exhibit uniform magnetization behavior despite the fact that the soft magnetic inclusions are too large to be magnetically coupled through inter-phase exchange interactions. In this study, we present the results of numerical simulation showing that in the case of a layered microstructure (typical of the die-upset composites) the long-range magnetostatic interactions assure smooth demagnetization curves. Still, at least partial exchange coupling is required to have an increased remanence. It is argued that the effect of magnetostatic coupling in composite magnets with a layered morphology considerably relaxes the strict requirements for the size of the soft inclusions and it may facilitate the future development of high-performance composite anisotropic permanent magnets.

    Data taken from tests involving heavy ions in the Berkeley 88 in. cyclotron being directed at low power Schottky barrier devices are reported. The tests also included trials in the Harvard cyclotron with 130 MeV protons, and at the U.C. Davis cyclotron using 56 MeV protons. The experiments were performed to study the single event upsets in MSI logic devices containing flip-flops. Results are presented of single-event upsets (SEU) causing functional degradation observed in post-exposure tests of six different devices. The effectiveness of the particles in producing SEUs in logic device functioning was found to be directly proportional to the proton energy. Shielding was determined to offer negligible protection from the particle bombardment. The results are considered significant for the design and fabrication of LS devices for space applications.

    1983-01-01

    Flight critical computer based control systems designed for advanced aircraft must exhibit ultrareliable performance in lightning charged environments. Digital system upset can occur as a result of lightning induced electrical transients, and a methodology was developed to test specific digital systems for upset susceptibility. Initial upset data indicates that there are several distinct upset modes and that the occurrence of upset is related to the relative synchronization of the transient input with the processing sate of the digital system. A large upset test data base will aid in the formulation and verification of analytical upset reliability modeling techniques which are being developed.

    2007-06-01

    We analyze the impact of retail rate design on the economics of grid-connected commercial photovoltaic (PV) systems in California. The analysis is based on 15-minute interval building load and PV production data for 24 commercial PV installations in California, spanning a diverse set of building load shapes and geographic locations. We derive the annual bill savings per kWh generated for each PV system, under each of 21 distinct retail rates currently offered by the five largest utilities in California. We identify and explain variation in the value of bill savings attributable to differences in the structure of demand and energy charges across rates, as well as variation attributable to other factors, such as the size of the PV system relative to building load, the specific shape of the PV production profile, and the customer load profile. We also identify the optimal rate for each customer, among those rates offered as alternatives to one another, and show how the decision is driven in large measure by the size of the PV system relative to building load. The findings reported here may be of value to regulators and utilities responsible for designing retail rates, as well as to customers and PV retailers who have a need to estimate the prospective bill savings of PV systems.

    1999-12-01

    The Single-word Multiple-bit Upset (SMU) frequency for nine commercial Static Random Access Memories (SRAM) have been evaluated at eight different neutron energies: 0-11MeV, 14MeV, 22MeV, 35MeV, 45MeV, 75MeV, 96MeV, 160MeV. The SRAM types used at these experiments have sizes from 256Kbit up to 1Mbit, with date-codes ranging from 9209 up to 9809. The result showed a slightly rising dependence on the neutron energy. Also experiments at two neutron energies, 45MeV and 96MeV, were performed where the supply voltage influence on the SMU-rate was studied. Five device types were used at 96MeV and the supply voltage was changed between 5V, 3.3V and 2.5V. At 45MeV three devices at 5V and 3.3V were irradiated. The experiments showed a relation between the amount of total upset and SMU that indicates no clear supply voltage dependence.

  3. How big is big? How often is often? Characterizing Texas petroleum refining upset air emissions

    McCoy, Britney J.; Fischbeck, Paul S.; Gerard, David

    2010-11-01

    This work examines the magnitude and frequency of Texas petroleum refineries upset air emissions over a 44-month period. Upset emissions occur during plant start-ups, shut-downs, maintenance, malfunctions and flaring incidents, and these emissions are typically exempt from regulation. These emissions contain a variety of chemicals, including benzene, nitrogen oxides, sulfur dioxide, and butadiene. Unlike other states, Texas has detailed reporting requirements, regulations in place, and an extensive upset emissions database. A key scientific and public policy question is whether upset emissions have significant impacts on local air quality and public health. However, it is not possible to address this question without first understanding the magnitude and properties of upsets. We merge related databases to examine over 3,900 upset emission events and find that upset emissions are significant in both size and occurrence when compared to routine operation emissions. It is determined that these events are not random, being more likely to occur during the summer, in the morning, and early in the workweek. A regional analysis of Port Arthur suggests that upset emissions from co-located refineries are equivalent to having an additional refinery within the region. Because of uncertainties within the reporting process and an obvious underestimation by some refineries, there is a need for better tracking of upset emissions.

    An asymmetric response latch providing immunity to single event upset without loss of speed is described. The latch has cross-coupled inverters having a hardened logic state and a soft state, wherein the logic state of the first inverter can only be changed when the voltage on the coupling node of that inverter is low and the logic state of the second inverter can only be changed when the coupling of that inverter is high. One of more of the asymmetric response latches may be configured into a memory cell having complete immunity, which protects information rather than logic states. 5 figures.

    The results of work done on the quantitative characterization of single-event upset (SEU) in bipolar random-access memories (RAMs) have been obtained through computer simulation of SEU in RAM cells that contain circuit models for bipolar transistors. The models include current generators that emulate the charge collected from ion tracks. The computer simulation results are compared with test data obtained from a RAM in a bipolar microprocessor chip. This methodology is applicable to other bipolar integrated circuit constructions in addition to RAM cells.

    Single-event upsets are studied in digital storage cells in 130nm CMOS bulk Si and PDSOI technologies. The sensitivity of SEU to different technologies and hardening approaches is explored by using heavy-ion radiation experiments. Error numbers in D flip-flop chains are used to determine the impact of various cell designs and PDSOI hardening technique on upset sensitivity. Various flip-flops are designed and connected as shift-register chains, and the error numbers induced by irradiation are recorded to examine the effectiveness of the PDSOI technology. It was found that PDSOI technology has better performance in terms of upset robustness versus bulk Si at the 130nm technology node. The same design structure implemented in PDSOI technology has higher SEU threshold LET and much lower saturation cross section due to its full dielectric isolation structure which does not allow the charge generated in the substrate to be collected by the electrically active junctions in the thin top region of the device and reduces the sensitive volume of p-n junctions in the transistor. As shown in the experiment result, NRH_SOI (not radiation hardening SOI) saves about 25% area while having much lower SER versus DICE_Si, which means PDSOI still has obvious advantage at reducing SEU rate, even though its necessary body contact has to consume certain extra area.

    During the last decade, multiple new methods of single event upset (SEU) rate prediction for aerospace systems have been proposed. Despite different models and approaches being employed in these methods, they all share relatively high usage complexity and require information about a device that is not always available to an end user. This work presents an alternative approach to estimating SEU cross-section as a function of linear energy transfer (LET) that can be further developed into a method of SEU rate prediction. The goal is to propose a simple, yet physics-based, approach with just two parameters that can be used even in situations when only a process node of the device is known. The developed approach is based on geometrical interpretation of SEU cross-section and an analytical solution to the diffusion problem obtained for a simplified IC topology model. A good fit of the model to the experimental data encompassing 7 generations of SRAMs is demonstrated.

    1991-12-01

    This research had two central goals: to examine the role of personality in (a) performing actions that anger spouses, and (b) eliciting anger-provoking actions from spouses. Personality data on a sample of married persons (N = 214) were obtained from three sources--self-report, spouse-observer report, and independent interviewers' reports. In a separate session, subjects recorded which of 147 upsetting actions their spouses had performed in the past year. A series of hierarchical multiple regressions revealed the effects of Surgency, Agreeableness, Conscientiousness, Emotional Stability, and Intellect on evoking upset in spouses through condescension (e.g., treating spouse as stupid or inferior), possessiveness (demanding too much time and attention), abuse (slapping spouse), unfaithfulness (having sex with others), inconsiderateness (leaving toilet seat up), moodiness (crying a lot), alcohol abuse (drinking too much alcohol), emotional constriction (hiding emotions to act tough), and self-centeredness (acting selfishly). Discussion of this research focuses on the implications of personality for conflict in marital relationships.

    temperature changes in the optical components. However, the corresponding recovery times of the optical components were found to be less than three hours, well within the seven hour limit posed by NW operations. Simulated laser shots also were found to create thermal upsets within the OM's optical components over a range of heat deposition rates. However, the recovery times of these thermal upsets were found to be less than one hour. Finally, the use of non-contact infrared thermocouples was demonstrated as an effective means to track the temperature of the OM's optics.

    2016-01-01

    A literature review was conducted to identify past efforts in providing control guidance for aircraft upset recovery including stall recovery. Because guidance is integrally linked to the intended function of aircraft attitude awareness and upset recognition, it is difficult, if not impossible, to consider these issues separately. This literature review covered the aspects of instrumentation and display symbologies for attitude awareness, aircraft upset recognition, upset and stall alerting, and control guidance. Many different forms of symbology have been investigated including, but not limited to, pitch scale depictions, attitude indicator icons, horizon symbology, attitude recovery arrows, and pitch trim indicators. Past research on different visual and alerting strategies that provide advisories, cautions, and warnings to pilots before entering an unusual attitude (UA) are also discussed. Finally, potential control guidance for recovery from upset or unusual attitudes, including approach-to-stall and stall conditions, are reviewed. Recommendations for future research are made.

    The Galileo probe will be subject to radiation fields and energetic particle bombardment during its outward bound journey and in orbit around Jupiter and its moons. To avoid the occurrence and propagation of effects of single event upset (SEU) bit state changes induced by the bombardments attempts were made to harden the Galileo electronics against SEUs. The hazards are especially acute for Schottky diode and low-power Schottky TTL parts. The preventive action options which were scheduled are reviewed, noting the selection of CMOS chips as replacements for SEU-susceptible devices. The simulation and risk assessment that were performed to evaluate the potential success of the replacements are summarized, with emphasis on the data employed to ensure the accuracy of the assessments and the predicted effects of SEUs in the various Galileo subsystems.

    The single event upset (SEU) imaging has been applied at the GSI heavy ion microprobe to determine the sensitivity of integrated circuits (IC) to heavy ion irradiation. This method offers the possibility to directly image those parts of an IC which are sensitive to ion-induced malfunctions. By a 3-dimensional simulation of charge collection across p-n-micro-junctions the authors can predict SEU cross-sections. For a MHS65162 2k [times] 8bit CMOS SRAM they found two regions per bit with different sensitivity and measured a total cross-section of (71[+-]18)[mu]m[sup 2] for a bitflip per cell and simulated 60[mu]m[sup 2] with an argon beam of 1.4 MeV/nucl. (LET of 19.7 MeV/mg/cm[sup 2]).

  14. Analysis of Control Strategies for Aircraft Flight Upset Recovery

    This paper proposes a framework for studying the ability of a control strategy, consisting of a control law and a command law, to recover an aircraft from ight conditions that may extend beyond the normal ight envelope. This study was carried out (i) by evaluating time responses of particular ight upsets, (ii) by evaluating local stability over an equilibrium manifold that included stall, and (iii) by bounding the set in the state space from where the vehicle can be safely own to wings-level ight. These states comprise what will be called the safely recoverable ight envelope (SRFE), which is a set containing the aircraft states from where a control strategy can safely stabilize the aircraft. By safe recovery it is implied that the tran- sient response stays between prescribed limits before converging to a steady horizontal ight. The calculation of the SRFE bounds yields the worst-case initial state corresponding to each control strategy. This information is used to compare alternative recovery strategies, determine their strengths and limitations, and identify the most e ective strategy. In regard to the control law, the authors developed feedback feedforward laws based on the gain scheduling of multivariable controllers. In regard to the command law, which is the mechanism governing the exogenous signals driving the feed- forward component of the controller, we developed laws with a feedback structure that combines local stability and transient response considera- tions. The upset recovery of the Generic Transport Model, a sub-scale twin-engine jet vehicle developed by NASA Langley Research Center, is used as a case study.

    2015-06-15

    Purpose: Surface mold applicators can be customized to fit irregular skin surfaces that are difficult to treat with other radiation therapy techniques. Optimal design of customized HDR skin brachytherapy is not well-established. We evaluated the impact of applicator thickness (source to skin distance) on target dosimetry. Methods: 27 patients had 34 treated sites: scalp 4, face 13, extremity 13, and torso 4. Custom applicators were constructed from 5–15 mm thick thermoplastic bolus molded over the skin lesion. A planar array of plastic brachytherapy catheters spaced 5–10 mm apart was affixed to the bolus. CT simulation was used to contour the target volume and to determine the prescription depth. Inverse planning simulated annealing followed by graphical optimization was used to plan and deliver 40–56 Gy in 8–16 fractions. Target coverage parameters (D90, Dmean, and V100) and dose uniformity (V110–200, D0.1cc, D1cc, and D2cc) were studied according to target depth (<5mm vs. ≥5mm) and applicator thickness (5–10mm vs. ≥10mm). Results: The average prescription depth was 4.2±1.5mm. The average bolus thickness was 9.2±2.4mm. The median CTV volume was 10.0 cc (0.2–212.4 cc). Similar target coverage was achieved with prescription depths of <5mm and ≥5mm (Dmean = 113.8% vs. 112.4% and D90 = 100.2% vs. 98.3%). The <5mm prescription depth plans were more uniform (D0.1cc = 131.8% vs. 151.8%). Bolus thickness <10mm vs. ≥10mm plans also had similar target coverage (Dmean = 118.2% vs. 110.7% and D90 = 100.1% vs. 99.0%). Applicators ≥10mm thick, however, provide more uniform target dosimetry (D0.1cc = 146.9% vs. 139.5%). Conclusion: Prescription depth is based upon the thickness of the lesion and upon the clinical needs of the patient. Applicators ≥10mm thick provide more dose uniformity than 5–10mm thick applicators. Applicator thickness is an important variable that should be considered during treatment planning to achieve optimal dose uniformity.

    This paper analyzes data from a single-event upset experiment conducted at the Los Alamos National Laboratory. Statistical tools, based on well-known x(sup 2) hypothesis testing theory, are used to determine if sequences of upsets can be modeled as a homogeneous Markov chain of a specific order. The experiment consisted of radiating a new experimental flight control computer (FCC) with a high intensity neutron beam while the FCC controlled a simulation of a Boeing 737. The analyzed data is a sequence of states that indicates when the FCC is under an upset condition.

    2006-01-01

    This paper seeks to present an analysis of the literature examining objective information concerning the subject of customer service, as it applies to the current medical practice. Hopefully, this information will be synthesized to generate a cogent approach to correlate customer service with quality. Articles were obtained by an English language search of MEDLINE from January 1976 to July 2005. This computerized search was supplemented with literature from the author's personal collection of peer-reviewed articles on customer service in a medical setting. This information was presented in a qualitative fashion. There is a significant lack of objective data correlating customer service objectives, patient satisfaction and quality of care. Patients present predominantly for the convenience of emergency department care. Specifics of satisfaction are directed to the timing, and amount of "caring". Demographic correlates including symptom presentation, practice style, location and physician issues directly impact on satisfaction. It is most helpful to develop a productive plan for the "difficult patient", emphasizing communication and empathy. Profiling of the customer satisfaction experience is best accomplished by examining the specifics of satisfaction, nature of the ED patient, demographic profile, symptom presentation and physician interventions emphasizing communication--especially with the difficult patient. The current emergency medicine customer service dilemmas are a complex interaction of both patient and physician factors specifically targeting both efficiency and patient satisfaction. Awareness of these issues particular to the emergency patient can help to maximize efficiency, minimize subsequent medicolegal risk and improve patient care if a tailored management plan is formulated.

    1984-01-01

    A methodology was developed a assess the upset susceptibility/reliability of a computer system onboard an aircraft flying through a lightning environment. Upset error modes in a general purpose microprocessor were studied. The upset tests involved the random input of analog transients which model lightning induced signals onto interface lines of an 8080 based microcomputer from which upset error data was recorded. The program code on the microprocessor during tests is designed to exercise all of the machine cycles and memory addressing techniques implemented in the 8080 central processing unit. A statistical analysis is presented in which possible correlations are established between the probability of upset occurrence and transient signal inputs during specific processing states and operations. A stochastic upset susceptibility model for the 8080 microprocessor is presented. The susceptibility of this microprocessor to upset, once analog transients have entered the system, is determined analytically by calculating the state probabilities of the stochastic model.

    You are a marketing director with $5 million to invest in customer acquisition and retention. Which customers do you acquire, and which do you retain? Up to a point, the choice is obvious: Keep the consistent big spenders and lose the erratic small ones. But what about the erratic big spenders and the consistent small ones? It's often unclear whether you should acquire or retain them and at what cost. Businesses have begun dealing with unpredictable customer behavior by following the practices of sophisticated investors who own portfolios comprising dozens of stocks with different, indeed divergent, histories and prospects. Each portfolio is diversified so as to produce the investor's desired returns at the particular level of uncertainty he or she can tolerate. Customers, too, are assets--risky assets. As with stocks, the cost of acquiring them is supposed to reflect the cash-flow values they are likely to generate. The authors explain how to construct a portfolio based on the notion that a customer's risk-adjusted lifetime value depends on its anticipated effect on the riskiness of the group it is joining. They also show how this approach was used to identify the best prospects for Myron Corporation, a global leader in the personalized business-gift industry. The concept of risk-adjusted lifetime value has a transforming power: For companies that rely on it, product managers will be replaced by customer managers, and the current method of accounting for profit and loss--which is by product--will be replaced by one that determines each customer's P&L. Once adjusted for risk, those P&Ls will become the firm's key performance and operational metric.

    The single event upset (SEU) response of 65 nm commercial double data rate static random access memory (SRAM) and quad data rate SRAM was investigated by using proton beams with energies in the range of 0.15 MeV to 8.0 MeV. Experimental results show that a significant number of SEU occurrences can be triggered when the energy of incident proton is below 1 MeV. For the low energy protons, the SEU cross section measured in these SRAMs was found to increase with increasing proton energy, attaining a peak value, and then decreases as the proton energy was further increased. While in case of quad data rate SRAMs, it seems that they are more sensitive to SEU occurrences as compared with double data rate SRAMs. The bias voltage and data pattern dependence on SEU cross section induced by the low energy protons were also investigated in this work. In addition, the over-layer thickness of the SRAMs and the impact of degrader use in proton induced SEU test were also analyzed in detail. Monte Carlo simulations results indicate that the use of degrader in case of low energy proton induced SEU test results in a significant reduction of the SEU cross section.

    A high-dose-rate (HDR) 192-Ir brachytherapy using a customized intraoral mold is effective for superficial oral cavity cancer, and the surrounding normal tissue is kept away from the radioactive source with gauze pads and/or mouth piece for reducing the dose on the normal tissues. In the Tokushima university hospital, the mold has a lead shield which utilizes the space prepared with sufficient border-molding by a specific dental technique using modeling compound. In HDR 192-Ir brachytherapy using a lead shielded customized intraoral mold, there are no reports measuring the absorbed dose. The purpose of the present study is to measure the absorbed dose and discuss the optimum thickness of lead in HDR 192-Ir brachytherapy using a customized intraoral mold with lead shield using a 1 cm thickness mimic mold. The thickness of lead in the mold could be changed by varying the arrangement of 0.1 cm thickness sheet of the acrylic resin plate and lead. The measured doses at the lateral surface of the mold with thermo-luminescence dosimeter were reduced to 1.12, 0.79, 0.57, 0.41, 0.31, 0.24 and 0.19 Gy and the ratios to the prescription dose were reduced to 56, 40, 29, 21, 16, 12 and 10 percent as lead thickness increased from 0 to 0.6 cm in 0.1 cm increments, respectively. A 0.3 cm thickness lead was considered to be required for a 1 cm thickness mold, and it was necessary to thicken the lead as much as possible with the constraint of limited space in the oral cavity, especially at the fornix vestibule.

    This report describes an approach for the assessment of upset resilience that is applicable to systems in general, including safety-critical, real-time systems. For this work, resilience is defined as the ability to preserve and restore service availability and integrity under stated conditions of configuration, functional inputs and environmental conditions. To enable a quantitative approach, we define novel system service degradation metrics and propose a new mathematical definition of resilience. These behavioral-level metrics are based on the fundamental service classification criteria of correctness, detectability, symmetry and persistence. This approach consists of a Monte-Carlo-based stimulus injection experiment, on a physical implementation or an error-propagation model of a system, to generate a system response set that can be characterized in terms of dimensional error metrics and integrated to form an overall measure of resilience. We expect this approach to be helpful in gaining insight into the error containment and repair capabilities of systems for a wide range of conditions.

    The National Aeronautics and Space Administration (NASA) utilizes adsorption technology as part of contaminant removal systems designed for long term missions. A variety of trace contaminants can be effectively removed from gas streams by adsorption onto activated carbon. An activated carbon adsorption column meets NASA's requirements of a lightweight and efficient means of controlling trace contaminant levels aboard spacecraft and space stations. The activated carbon bed is part of the Trace Contaminant Control System (TCCS) which is utilized to purify the cabin atmosphere. TCCS designs oversize the adsorption columns to account for irregular fluctuations in cabin atmospheric conditions. Variations in the cabin atmosphere include changes in contaminant concentrations, temperature, and relative humidity. Excessively large deviations from typical conditions can result from unusual crew activity, equipment malfunctions, or even fires. The research carried out under this award focussed in detail on the effects of cabin upsets on the performance of activated carbon adsorption columns. Both experiments and modeling were performed with an emphasis on the roll of a change in relative humidity on adsorption of trace contaminants. A flow through fixed-bed apparatus was constructed at the NASA Ames Research Center, and experiments were performed there. Modeling work was performed at the University of Virginia.

    To assess whether youth are upset by being asked questions about sensitive kinds of abuse, victimization, family maltreatment, and sexual victimization in the course of standard epidemiological surveys. A national sample of youth aged 10-17 were interviewed on the telephone by experienced interviewers as part of the National Survey of Children Exposed to Violence. At the end they were asked whether answering questions had upset them. Of the youth interviewed, 4.5% reported being at all upset and 0.8% reported being pretty or a lot upset. However, only a minority of those upset, .3% of the total sample, said they would not participate again had they known about the content. But even in this group, the regret about participation was mostly due to the length of the survey, not the types of questions being asked. Thus, asking about exposure to abuse and sensitive kinds of victimization in standard interview surveys is associated with low levels of respondent upset due to the nature of the questions.

    We derive analytical models of the excess carrier density distribution and the HPM (high-power microwave) upset susceptibility with dependence of pulse-width, which are validated by the simulated results and experimental data. Mechanism analysis and model derivation verify that the excess carriers dominate the current amplification process of the latch-up. Our results reveal that the excess carrier density distribution in P-substrate behaves as pulse-width dependence. The HPM upset voltage threshold Vp decreases with the incremental pulse-width, while there is an inflection point which is caused because the excess carrier accumulation in the P-substrate will be suppressed over time. For the first time, the physical essence of the HPM pulse-width upset effect is proposed to be the excess carrier accumulation effect. Validation concludes that the Vp model is capable of giving a reliable and accurate prediction to the HPM upset susceptibility of a CMOS inverter, which simultaneously considers technology information, ambient temperature, and layout parameters. From the model, the layout parameter LB has been demonstrated to have a significant impact on the pulse-width upset effect: a CMOS inverter with minor LB is more susceptible to HPM, which enables us to put forward hardening measures for inverters that are immune from the HPM upset.

    This paper summarizes the radiation testing performed on the Xilinx Kintex-7 FPGA in an effort to determine if the Kintex-7 can be used within the ATLAS Liquid Argon (LAr) Calorimeter. The Kintex-7 device was tested with wide-spectrum neutrons, protons, heavy-ions, and mixed high-energy hadron environments. The results of these tests were used to estimate the configuration ram and block ram upset rate within the ATLAS LAr. These estimations suggest that the configuration memory will upset at a rate of 1.1 × 10-10 upsets/bit/s and the bram memory will upset at a rate of 9.06 × 10-11 upsets/bit/s. For the Kintex 7K325 device, this translates to 6.85 × 10-3 upsets/device/s for configuration memory and 1.49 × 10-3 for block memory.

    One hypothesis derived from evolutionary perspectives is that men are more upset than women by sexual infidelity and women are more upset than men by emotional infidelity. The proposed explanation is that men, in contrast to women, face the risk of unwittingly investing in genetically unrelated offspring. Most studies, however, have relied on small college or community samples of heterosexual participants. We examined upset over sexual versus emotional jealousy among 63,894 gay, lesbian, bisexual, and heterosexual participants. Participants imagined which would upset them more: their partners having sex with someone else (but not falling in love with them) or their partners falling in love with someone else (but not having sex with them). Consistent with this evolutionary perspective, heterosexual men were more likely than heterosexual women to be upset by sexual infidelity (54 vs. 35 %) and less likely than heterosexual women to be upset by emotional infidelity (46 vs. 65 %). This gender difference emerged across age groups, income levels, history of being cheated on, history of being unfaithful, relationship type, and length. The gender difference, however, was limited to heterosexual participants. Bisexual men and women did not differ significantly from each other in upset over sexual infidelity (30 vs. 27 %), regardless of whether they were currently dating a man (35 vs. 29 %) or woman (28 vs. 20 %). Gay men and lesbian women also did not differ (32 vs. 34 %). The findings present strong evidence that a gender difference exists in a broad sample of U.S. adults, but only among heterosexuals.

    Charged-particle interactions in microelectronic circuit chips (integrated circuits) present a particularly insidious problem for solid-state electronic systems due to the generation of soft errors or single-particle event upset (SEU) by either cosmic rays or other radiation sources. Particle accelerators are used to provide both light and heavy ions in order to assess the propensity of integrated circuit chips for SEU. Critical aspects of this assessment involve the ability to analytically model SEU for the prediction of error rates in known radiation environments. In order to accurately model SEU, the measurement and prediction of energy deposition in the form of an electron-hole plasma generated along an ion track is of paramount importance. This requires the use of accelerators which allow for ease in both energy control (change of energy) and change of ion species. This and other aspects of ion-beam control and diagnostics (e.g., uniformity and flux) are of critical concern for the experimental verification of theoretical SEU models.

    Over the past decade, the goal of reducing the fatal accident rate of large transport aircraft has resulted in research aimed at the problem of aircraft loss-of-control. Starting in 1999, the NASA Aviation Safety Program initiated research that included vehicle dynamics modeling, system health monitoring, and reconfigurable control systems focused on flight regimes beyond the normal flight envelope. In recent years, there has been an increased emphasis on adaptive control technologies for recovery from control upsets or failures including damage scenarios. As part of these efforts, NASA has developed the Airborne Subscale Transport Aircraft Research (AirSTAR) flight facility to allow flight research and validation, and system testing for flight regimes that are considered too risky for full-scale manned transport airplane testing. The AirSTAR facility utilizes dynamically-scaled vehicles that enable the application of subscale flight test results to full scale vehicles. This paper describes the modeling and simulation approach used for AirSTAR vehicles that supports the goals of efficient, low-cost and safe flight research in abnormal flight conditions. Modeling of aerodynamics, controls, and propulsion will be discussed as well as the application of simulation to flight control system development, test planning, risk mitigation, and flight research.

    This paper focuses on the methodology analysis for the stability and the corresponding tracking performance of a closed-loop digital jump linear control system with a stochastic switching signal. The method is applied to a flight control system. A distributed recoverable platform is implemented on the flight control system and subject to independent digital upsets. The upset processes are used to stimulate electromagnetic environments. Specifically, the paper presents the scenarios that the upset process is directly injected into the distributed flight control system, which is modeled by independent Markov upset processes and independent and identically distributed (IID) processes. A theoretical performance analysis and simulation modelling are both presented in detail for a more complete independent digital upset injection. The specific examples are proposed to verify the methodology of tracking performance analysis. The general analyses for different configurations are also proposed. Comparisons among different configurations are conducted to demonstrate the availability and the characteristics of the design.

    A growing literature shows that even the symbolic presence of an attachment figure facilitates the regulation of negative affect triggered by external stressors. Yet, in daily life, pernicious stressors are often internally generated--recalling an upsetting experience reliably increases negative affect, rumination, and susceptibility to physical and psychological health problems. The present research provides the first systematic examination of whether activating the mental representation of an attachment figure enhances the regulation of affect triggered by thinking about upsetting memories. Using 2 different techniques for priming attachment figure representations and 2 types of negative affect measures (explicit and implicit), activating the mental representation of an attachment figure (vs. an acquaintance or stranger) after recalling an upsetting memory enhanced recovery--eliminating the negative effects of the memory recall (Studies 1-3). In contrast, activating the mental representation of an attachment figure before recalling an upsetting memory had no such effect (Studies 1 and 2). Furthermore, activating the mental representation of an attachment figure after thinking about upsetting memories reduced negative thinking in a stream of consciousness task, and the magnitude of the attachment-induced affective recovery effects as assessed with explicit affect measures predicted mental and physical health in daily life (Study 3). Finally, a meta-analysis of the 3 studies (Study 4) showed that the regulatory benefits conferred by the mental representation of an attachment figure were weaker for individuals high on attachment avoidance. The implications of these findings for attachment, emotion regulation, and mental and physical health are discussed.

    The characteristics Of ion-induced charge collection and single-event upset are studied in SOI transistors and circuits with various body tie structures. Impact ionization effects including single-event snapback are shown to be very important. Focused ion microbeam experiments are used to find single-event snapback drain voltage thresholds in n-channel SOI transistors as a function of device width. Three-Dimensional device simulations are used to determine single-event upset and snapback thresholds in SOI SRAMS, and to study design tradeoffs for various body-tie structures. A window of vulnerability to single-event snapback is shown to exist below the single-event upset threshold. The presence of single-event snapback in commercial SOI SRAMS is confirmed through broadbeam ion testing, and implications for hardness assurance testing of SOI integrated circuits are discussed.

    It has been observed that atmospheric neutrons can produce single event upsets in digital flight control hardware. The phenomenon has been studied extensively at the chip level, and now system level experiments are underway. In this paper analytical closed-loop performance measures for the tracking error are developed for a plant that is stabilized by a recoverable computer system subject to neutron induced upsets. The underlying model is a Markov jump-linear system with process noise. The steady-state tracking error is expressed in terms of a generalized observability Gramian.

The vessels differ from production reservoirs in design, material, and fabrication process. One set was made from forged 304L stainless steel and the other from forged 316L stainless steel. Six vessels of each type were loaded with a tritium mix in November 1995 and placed in storage at 71 C. This memo describes and documents the fabrication of the twelve vessels.

    Flight test and modeling techniques were developed for efficiently identifying global aerodynamic models that can be used to accurately simulate stall, upset, and recovery on large transport airplanes. The techniques were developed and validated in a high-fidelity fixed-base flight simulator using a wind-tunnel aerodynamic database, realistic sensor characteristics, and a realistic flight deck representative of a large transport aircraft. Results demonstrated that aerodynamic models for stall, upset, and recovery can be identified rapidly and accurately using relatively simple piloted flight test maneuvers. Stall maneuver predictions and comparisons of identified aerodynamic models with data from the underlying simulation aerodynamic database were used to validate the techniques.

    Records of bit flips in the Cray-1 computer installed at Los Alamos in 1976 lead to an upset rate in the Cray-1 's bipolar SRAMs that correlates with the SEUs being induced by the atmospheric neutrons. In 1976 the Cray Research Company delivered its first supercomputer, the Cray-1, installing it at Los Alamos National Laboratory. Los Alamos had competed with the Lawrence Livermore National Laboratory for the Cray-1 and won, reaching an agreement with Seymour Cray to install the machine for a period of six months for free, after which they could decide whether to buy, lease or return it. As a result, Los Alamos personnel kept track of the computer reliability and performance and so we know that during those six months of operation, 152 memory parity errors were recorded. The computer memory consisted of approximately 70,000 1Kx1 bipolar ECL static RAMs, the Fairchild 10415. What the Los Alamos engineers didn't know is that those bit flips were the result of single event upsets (SEUs) caused by the atmospheric neutrons. Thus, these 152 bit flips were the first recorded SEUs on the earth, and were observed 2 years before the SEUs in the Intel DRAMs that had been found by May and Woods in 1978. The upsets in the DRAMs were shown to have been caused by alpha particles from the chip packaging material. In this paper we will demonstrate that the Cray-1 bit flips, which were found through the use of parity bits in the Cray-1, were likely due to atmospheric neutrons. This paper will follow the same approach as that of the very first paper to demonstrate single event effects, which occurred in satellite flip-flop circuits in 1975. The main difference is that in the four events that occurred over the course of 17 satellite years of operation were shown to be due to single event effects just a few years after those satellite anomalies were recorded. In the case of the Cray-1 bit flips, there has been a delay of more than 30 years between the occurrence of the bit flips and the

    The single event effects and hardening of a 0.15 /spl mu/m antifuse FPGA, the AX device, were investigated by beam test and computer simulation. The beam test showed no permanent damage mode. Functional failures were observed and attributed to the upsets in a control logic circuit, the startup sequencer. Clock upsets were observed and attributed to the single event transients in the clock network. Upsets were also measured in the user flip-flop and embedded SRAM. The hardening technique dealing with each upset mode is discussed in detail. SPICE and three-dimensional mixed-mode simulations were used to determine the design rules for mitigating the multiple upsets due to glancing angle and charge sharing. The hardening techniques have been implemented in the newly fabricated RTAXS device. Preliminary heavy-ion-beam test data show that all the hard-wired hardening solutions are working successfully.

    Advanced composite aircraft designs include fault-tolerant computer-based digital control systems with thigh reliability requirements for adverse as well as optimum operating environments. Since aircraft penetrate intense electromagnetic fields during thunderstorms, onboard computer systems maya be subjected to field-induced transient voltages and currents resulting in functional error modes which are collectively referred to as digital system upset. A methodology was developed for assessing the upset susceptibility of a computer system onboard an aircraft flying through a lightning environment. Upset error modes in a general-purpose microprocessor were studied via tests which involved the random input of analog transients which model lightning-induced signals onto interface lines of an 8080-based microcomputer from which upset error data were recorded. The application of Markov modeling to upset susceptibility estimation is discussed and a stochastic model development.

    The investigation has been undertaken to develop and study the upsetting characteristics of iron-based sintered porous components by using elemental powders through powder metallurgical techniques. The paper presents experimental results of forming Fe-based sintered porous samples and upsetting it by two methods. The first method involves upsetting between two flat plates (anvils). The second method is based on the deformation of the material in closed-die. The study compares the graphs of variation of the force vs. displacement. The aim of the article is to compare the experimental characteristics of upsetting process of samples with different porosities. Metallic porous structure was obtained as a result of sintering processes Fe-based powders mixtures with addition of copper catalyst and Fe (III) oxide as a space holder. The sintering was proceeded at the temperature of 1130OC and 50 min. long, in dissociated ammonia protective gas. Some samples were sintered with addition of powdered activated carbon to increase its porosity properties and change chemical composition.

    This work reports the effect of NdF3, DyF3, and CaF2 additions on the electrical resistivity and magnetic properties of Pr-Fe-B hot-pressed and die-upset permanent magnets. Composite magnets were synthesized from ground Pr14.5Fe79.5B6 melt-spun ribbons blended with 5wt% of fluoride fine powders and consolidated by hot pressing at 650°C, followed by die upsetting at 800°C. While CaF2 is stable at the processing temperatures, the rare earth atoms separate from their fluorides to a certain degree with the assistance of the Pr-rich phase from the magnet matrix. Addition of fluorides increased the resistivity of the hot-pressed specimens by more than 200%. The resistivity of the die-upset specimens measured perpendicularly to the direction of the applied pressure, which is also the direction of magnetization, is, however, only slightly increased compared to the magnet counterparts without the fluoride addition. The intrinsic coercivity of Pr14.5Fe79.5B6 die-upset specimens is increased from 14.5kOe to 15.3, 17.1, and 17.7kOe for the addition of CaF2, DyF3, and NdF3, respectively, at a slight expense of the residual flux.

    Upset thresholds for bulk CMOS and CMOS/SOS RAMS were deduced after bombardment of the devices with 140 MeV Kr, 160 MeV Ar, and 33 MeV O beams in a cyclotron. The trials were performed to test prototype devices intended for space applications, to relate feature size to the critical upset charge, and to check the validity of computer simulation models. The tests were run on 4 and 1 K memory cells with 6 transistors, in either hardened or unhardened configurations. The upset cross sections were calculated to determine the critical charge for upset from the soft errors observed in the irradiated cells. Computer simulations of the critical charge were found to deviate from the experimentally observed variation of the critical charge as the square of the feature size. Modeled values of series resistors decoupling the inverter pairs of memory cells showed that above some minimum resistance value a small increase in resistance produces a large increase in the critical charge, which the experimental data showed to be of questionable validity unless the value is made dependent on the maximum allowed read-write time.

    The data summarized describe single event upset (bit-flips) for 60 device types having data storage elements. The data are from 15 acceleration tests with both protons and heavier ions. Tables are included summarizing the upset threshold data and listing the devices tested for heavy ion induced bit-flip and the devices tested with protons. With regard to the proton data, it is noted that the data are often limited to one proton energy, since the tests were usually motivated by the engineering requirement of comparing similar candidate devices for a system. It is noted that many of the devices exhibited no upset for the given test conditions (the maximum fluence and the maximum proton energy Ep are given for these cases). It is believed, however, that some possibility of upset usually exists because there is a slight chance that the recoil atom may receive up to 10 to 20 MeV of recoil energy (with more energy at higher Ep).

Their object oriented use of standard and custom controls enable a user to build extremely powerful applications. A multipurpose, database enabled programming environment that can provide an event driven interface functions as a multimedia kernel. This kernel can provide a variety of authoring solutions (e.g. a timeline based model similar to Macromedia Director or a node authoring model similar to Icon Author). At the heart of the kernel is a set of low level multimedia components providing object oriented interfaces for graphics, audio, video and imaging. Data preparation tools (e.g., layout, palette and Sprite Editors) could be built to manage the media database. The flexible interface for VB allows the construction of an infinite number of user models. The proliferation of these models within a popular, easy to use environment will allow the vast developer segment of 'producer' types to bring their ideas to the market. This is the key to building exciting, content rich multimedia solutions. Microsoft's VB and Borland's Delphi environments combined with multimedia components enable these possibilities.

    The influence of the metric of linear energy transfer (LET) on single event upset (SEU), particularly multiple bit upset (MBU) in a hypothetical 90-nm static random access memory (SRAM) is explored. To explain the odd point of higher LET incident ion but induced lower cross section in the curve of SEU cross section, MBUs induced by incident ions 132Xe and 209Bi with the same LET but different energies at oblique incidence are investigated using multi-functional package for single event effect analysis (MUFPSA). In addition, a comprehensive analytical model of the radial track structure is incorporated into MUFPSA, which is a complementation for assessing and interpreting MBU susceptibility of SRAM. The results show that (i) with the increase of incident angle, MBU multiplicity and probability each present an increasing trend; (ii) due to the higher ion relative velocity and longer range of δ electrons, higher energy ions trigger the MBU with less probability than lower energy ions.

    Self-efficacy for controlling upsetting thoughts was examined as a predictor of emotional eating by family caregivers of physically and cognitively impaired older adults. Adult women (N = 158) providing healthcare assistance for an older family member completed an online survey about caregiving stressors, depressive symptoms, self-efficacy, and emotional eating. A stress process framework was used as a conceptual model to guide selection of variables predicting emotional eating scores. A hierarchical multiple regression was conducted and the overall model was significant (R(2) = .21, F(4,153) = 10.02, p < .01); self-efficacy for controlling upsetting thoughts was a significant predictor of caregivers' emotional eating scores after accounting for IADL, role overload, and depression scores. These findings replicate previous research demonstrating the relationship between managing cognitions about caregiving and behavioral responses to stressors, and point to the importance of addressing cognitive processes in efforts to improve caregiver health behaviors.

  16. Solid-state resistance upset welding: A process with unique advantages for advanced materials

    SciTech Connect

    Kanne, W.R. Jr.

    1993-12-31

    Solid-state resistance upset welding is suitable for joining many alloys that are difficult to weld using fusion processes. Since no melting takes place, the weld metal retains many of the characteristics of the base metal. Resulting welds have a hot worked structure, and thereby have higher strength than fusion welds in the same mate. Since the material being joined is not melted, compositional gradients are not introduced, second phase materials are minimally disrupted, and minor alloying elements, do not affect weldability. Solid-state upset welding has been adapted for fabrication of structures considered very large compared to typical resistance welding applications. The process has been used for closure of capsules, small vessels, and large containers. Welding emphasis has been on 304L stainless steel, the material for current applications. Other materials have, however, received enough attention to have demonstrated capability for joining alloys that are not readily weldable using fusion welding methods. A variety of other stainless steels (including A-286), superalloys (including TD nickel), refractory metals (including tungsten), and aluminum alloys (including 2024) have been successfully upset welded.

    The hydrogenation disproportionation desorption recombination (HDDR) process was applied to produce isotropic, submicron 0022-3727/31/7/009/img6 powder in 500 g batches in a specially designed HDDR reactor. The hot pressing characteristics of the material were determined and it was shown that the material has an excellent stability against grain growth. The coercivity of 1000-1080 0022-3727/31/7/009/img7 is almost constant over a hot pressing temperature range of 700-0022-3727/31/7/009/img8, making the material highly suitable for subsequent hot deformation. Die-upset HDDR magnets were prepared in order to study the basic deformation behaviour. A remanence of 1.13 T in the axial direction and a coercivity of 0022-3727/31/7/009/img9 were achieved. Similar properties were obtained for the backward extruded magnets produced at 0022-3727/31/7/009/img10 and only a small decrease in alignment along the axial direction of the ring was found. Grain sizes were very uniform and on the submicron scale. Platelet-shaped grains were observed in the die-upset magnets. The formation of interaction domains, along the axial and radial directions for the die-upset and backward extruded magnets respectively, were established by high-resolution Kerr microscopy. The high degree of texture in the hot deformed HDDR magnets was also confirmed by Lorentz microscopy revealing continuous equispaced domains extending over the entire thinned sample with only small directional variations.

    In order to optimize the magnetic properties of die-upset Pr-Fe-B magnets, we have systematically altered alloy compositions, including partial substitution of cobalt and neodymium, and low-level additions of gallium. In general, the remanences of Pr-Fe-B die-upset magnets were lower by [similar to]1 kG, and coercivities were higher by [similar to]4 kOe, than analogous Nd-Fe-B magnets. The microstructure of the Pr-Fe-B die-upset magnets was similar to Nd-Fe-B magnets. Both systems are two phase, consisting of oriented flat platelet-shaped grains of 2-14-1 separated by a rare earth-rich intergranular phase. The intergranular phase is thicker for the Pr-Fe-B magnets, resulting in enhanced magnetic domain wall pinning and increased coercivity. Even higher coercivities were obtained with small amounts of cobalt substitution ([le]5 at. % of the transition metal) and by very low-level additions of gallium ([le]0.5 at. %).

    Massachusetts utilities and utility detractors all object to Governor King's position stated at a March press conference and urging regulators to deny rate increases that he claimed would be paying for utility mistakes. Boston Edison's request for a $291 million rate increase would recover the money lost when the utility abandoned its Pilgrim II nuclear plant. Boston Gas is seeking $46 million to recover money lost during last winter's shortage of natural gas. The governor's timing and mode of intervention prompted most of the criticism because of their political ramifications during an election year. Most of his statements drew upon materials from a consumer group called Fair Share, but were stated in a way that the governor's re-election is necessary to secure the desired effects. (DCK)

    We investigate the issue of radiation-induced failures in electronic devices by developing a Monte Carlo tool called MC-Oracle. It is able to transport the particles in device, to calculate the energy deposited in the sensitive region of the device and to calculate the transient current induced by the primary particle and the secondary particles produced during nuclear reactions. We compare our simulation results with SRAM experiments irradiated with neutrons, protons and ions. The agreement is very good and shows that it is possible to predict the soft error rate (SER) for a given device in a given environment.

    In order to estimate the influence of genetic and environmental factors on 'crying without a cause' and 'being easily upset' in 2-year-old children, a large twin study was carried out. Prospective data were available for ~18,000 2-year-old twin pairs from the Netherlands Twin Register. A bivariate genetic analysis was performed using structural equation modeling in the Mx software package. The influence of maternal personality characteristics and demographic and lifestyle factors was tested to identify specific risk factors that may underlie the shared environment of twins. Furthermore, it was tested whether crying without a cause and being easily upset were predictive of later internalizing, externalizing and attention problems. Crying without a cause yielded a heritability estimate of 60% in boys and girls. For easily upset, the heritability was estimated at 43% in boys and 31% in girls. The variance explained by shared environment varied between 35% and 63%. The correlation between crying without a cause and easily upset (r = .36) was explained both by genetic and shared environmental factors. Birth cohort, gestational age, socioeconomic status, parental age, parental smoking behavior and alcohol use during pregnancy did not explain the shared environmental component. Neuroticism of the mother explained a small proportion of the additive genetic, but not of the shared environmental effects for easily upset. Crying without a cause and being easily upset at age 2 were predictive of internalizing, externalizing and attention problems at age 7, with effect sizes of .28-.42. A large influence of shared environmental factors on crying without a cause and easily upset was detected. Although these effects could be specific to these items, we could not explain them by personality characteristics of the mother or by demographic and lifestyle factors, and we recognize that these effects may reflect other maternal characteristics.

    Anyone who has signed up for cell phone service, attempted to claim a rebate, or navigated a call center has probably suffered from a company's apparent indifference to what should be its first concern: the customer experiences that culminate in either satisfaction or disappointment and defection. Customer experience is the subjective response customers have to direct or indirect contact with a company. It encompasses every aspect of an offering: customer care, advertising, packaging, features, ease of use, reliability. Customer experience is shaped by customers' expectations, which largely reflect previous experiences. Few CEOs would argue against the significance of customer experience or against measuring and analyzing it. But many don't appreciate how those activities differ from CRM or just how illuminating the data can be. For instance, the majority of the companies in a recent survey believed they have been providing "superior" experiences to customers, but most customers disagreed. The authors describe a customer experience management (CEM) process that involves three kinds of monitoring: past patterns (evaluating completed transactions), present patterns (tracking current relationships), and potential patterns (conducting inquiries in the hope of unveiling future opportunities). Data are collected at or about touch points through such methods as surveys, interviews, focus groups, and online forums. Companies need to involve every function in the effort, not just a single customer-facing group. The authors go on to illustrate how a cross-functional CEM system is created. With such a system, companies can discover which customers are prospects for growth and which require immediate intervention.

    An integrated system mitigates the effects of a single event upset (SEU) on a reprogrammable field programmable gate array (RFPGA). The system includes (i) a RFPGA having an internal configuration memory, and (ii) a memory for storing a configuration associated with the RFPGA. Logic circuitry programmed into the RFPGA and coupled to the memory reloads a portion of the configuration from the memory into the RFPGA's internal configuration memory at predetermined times. Additional SEU mitigation can be provided by logic circuitry on the RFPGA that monitors and maintains synchronized operation of the RFPGA's digital clock managers.

The spread in the neutral threshold voltage appears to be too low to quantitatively explain the experimental observations in terms of simple charge loss, at least in SLC devices. The possibility that memories exposed to high energy protons and heavy ions exhibit negative charge transfer between programmed and erased cells is investigated, although the analysis does not provide conclusive support to this hypothesis.

    Radiation-induced upset levels in SA3001 static random access memories (SRAM's) and SA 3246 clock integrated circuits (IC's) have been measured in a medium-energy flash X-ray environment (average photon energy {approximately}100 keV) where dose-enhancing effects are very important. By comparing device responses using a non-dose-enhancing ceramic package lid and a dose-enhancing Kovar/gold lid, dose-enhancement factors for photocurrent and upset were generated. The observed upset enhancement factors of 3.0 {plus minus} 0.5 (SRAM) and 2.2 {plus minus} 0.2 (clock IC) are in excellent agreement with measurements of photocurrent enhancement factors (2.5 {plus minus} 0.5) in diodes processed with the same diffusions as the complementary metal-oxide-semiconductor (CMOS) IC's irradiated in a steady-state X-ray environment. These results indicate that upset is dominated by the radiation-induced transient supply current in these IC's, and that steady-state diode photocurrent measurements are a good predictor of both photocurrent and upset enhancement for IC's made with this technology.

    To realize the full potential of CQI, the needs of internal customers throughout the health care organization must be met. This is best done through a collaborative customer-supplier dialogue, where suppliers take the initiative to understand their internal customers' needs and make their own requirements clear. Unfortunately, physicians--the most critical group of internal customers--are unaccustomed to collaborative efforts and are often unwilling to participate in CQI training. The solution is to use the customer-supplier dialogue to understand physicians' unique needs so that they can be trained effectively and drawn into the CQI process.

    A government agency commissioned a baseline study of how its customers view the agency's risk information. The 70% response rate to a mail survey allows analysis by subgroups representing customers' primary interests. Although this agency traditionally has been responsible for ensuring plant and animal health at the farm gate (or where imported), responses emphasized emerging customer concerns about the environment and human health. Customers think many risk communication activities are important, but that the agency is not especially effective in conducting those activities. Customers are moderately satisfied with much of the risk information they receive, although many have little contact from or interaction with the agency. Customers identified other sources they use, which suggest potentially effective channels for this agency's risk messages. The study provides a baseline for measuring change in the agency's risk communication effectiveness. It also can be a model when other organizations plan their own risk communication evaluations.

  16. Customized ATP towpreg

    Sandusky, Donald A.; Marchello, Joseph M.; Baucom, Robert M.; Johnston, Norman J.

    Automated tow placement (ATP) utilizes robotic technology to lay down adjacent polymer-matrix-impregnated carbon fiber tows on a tool surface. Consolidation and cure during ATP requires that void elimination and polymer matrix adhesion be accomplished in the short period of heating and pressure rolling that follows towpreg ribbon placement from the robot head to the tool. This study examined the key towpreg ribbon properties and dimensions which play a significant role in ATP. Analysis of the heat transfer process window indicates that adequate heating can be achieved at lay down rates as high as 1 m/sec. While heat transfer did not appear to be the limiting factor, resin flow and fiber movement into tow lap gaps could be. Accordingly, consideration was given to towpreg ribbon having uniform yet non-rectangular cross sections. Dimensional integrity of the towpreg ribbon combined with customized ribbon architecture offer great promise for processing advances in ATP of high performance composites.

    As part of NASA's Aviation Safety and Security Program, a simulation study of a twinjet transport airplane crew training simulation was conducted to address fidelity for upset or loss of control conditions and to study the effect of flap configuration in those regimes. Piloted and desktop simulations were used to compare the baseline crew training simulation model with an enhanced aerodynamic model that was developed for high-angle-of-attack conditions. These studies were conducted with various flap configurations and addressed the approach-to-stall, stall, and post-stall flight regimes. The enhanced simulation model showed that flap configuration had a significant effect on the character of departures that occurred during post-stall flight. Preliminary comparisons with flight test data indicate that the enhanced model is a significant improvement over the baseline. Some of the unrepresentative characteristics that are predicted by the baseline crew training simulation for flight in the post-stall regime have been identified. This paper presents preliminary results of this simulation study and discusses key issues regarding predicted flight dynamics characteristics during extreme upset and loss-of-control flight conditions with different flap configurations.

    Electronics in spacecraft and satellites are exposed to high-energy cosmic radiation. In addition, terrestrial radiation can also affect earth-based electronics. To study the effects of radiation upon integrated circuits and to insure the reliability of electronic devices, cosmic and terrestrial radiations are simulated with ion beams from particle accelerators. A new, higher Linear Energy Transfer (LET) acceleration system for heavy ions has been developed at Sandia National Laboratories. Heavy ions from a 6.5 MV EN tandem Van de Graaff accelerator at 0.25 MeV/amu are injected into a two-stage Radio Frequency Quadrupole (RFQ) linac, which accelerates the ions to 1.9 MeV/amu. These ions together with those from the Brookhaven National Laboratory MP Tandem have been used to measure single event upset (SEU) cross sections as a function of LET for both bulk and Silicon on Insulator (SOI) Complementary Metal Oxide Semiconductor, Static Random Access Memories. The magnitudes of these cross sections indicate that the upsets in both the SOI and bulk parts are caused by OFF-drain strikes.

    The magnetic properties of NdFeB magnets are strongly affected by crystallographic texture which is highly associated with particle orientation. This study proposed a method for predicting the particle orientation in the simple upsetting process of NdFeB magnets. The method is based on finite element simulation with flow net analysis. The magnets in a cylindrical form were compressed by two flat dies in a chamber filled with argon at 750°C. Three forming speeds were taken into account in order to obtain flow stress curves used in simulations. The micrographs of the cross sections of the deformed magnets show that the particle deformation significantly increases with the compression. The phenomenon was also predicted by the proposed method. Both simulated and experimental results show that the inhomogeneity of the texture of the NdFeB magnets can be increased by the simple upsetting process. The predicted particle orientations were in a good agreement with those examined in the deformed magnets. The proposed method for predicting particle orientations can also be used in other forming processes of NdFeB magnets.

    The development of flight control systems to enhance aircraft safety during periods of vehicle impairment or degraded operations has been the focus of extensive work in recent years. Conditions adversely affecting aircraft flight operations and safety may result from a number of causes, including environmental disturbances, degraded flight operations, and aerodynamic upsets. To enhance the effectiveness of adaptive and envelope limiting controls systems, it is desirable to examine methods for identifying the occurrence of anomalous conditions and for assessing the impact of these conditions on the aircraft operational limits. This paper describes initial work performed toward this end, examining the use of fault detection methods applied to the aircraft for aerodynamic performance degradation identification and model-based methods for envelope prediction. Results are presented in which a model-based fault detection filter is applied to the identification of aircraft control surface and stall departure failures/upsets. This application is supported by a distributed loading aerodynamics formulation for the flight dynamics system reference model. Extensions for estimating the flight envelope due to generalized aerodynamic performance degradation are also described.

    Radiation hardening parts are to be used for satellites and nuclear power plants due to various kinds of radiation particles in space and radiation environment. Here, our focus is to implement a testing board of AVR Microcontroller checking for Single Event Upsets (SEU); the effects of protons on the electronic devices. The SEU results form the level change of stored information due to photon radiation and temperature in the space environment. The impact of SEU on PLD (Programmable Logic Devices) technology is most apparent in SRAM/ROM/DRAM devices wherein the state of storage cell can be upset. In this research, a simple and powerful test technique is suggested, and the results are presented for the analysis and future reference. In our experiment, the proton radiation facility (having the energy of 30 MeV with a beam current of 20 uA in the cyclotron) available at KIRAMS (Korea Institute of Radiological Medical Sciences) has been applied on two kinds of commercially available SRAM and EEPROM.

    Formal robustness analysis of aircraft control upset prevention and recovery systems could play an important role in their validation and ultimate certification. Such systems (developed for failure detection, identification, and reconfiguration, as well as upset recovery) need to be evaluated over broad regions of the flight envelope and under extreme flight conditions, and should include various sources of uncertainty. However, formulation of linear fractional transformation (LFT) models for representing system uncertainty can be very difficult for complex parameter-dependent systems. This paper describes a preliminary LFT modeling software tool which uses a matrix-based computational approach that can be directly applied to parametric uncertainty problems involving multivariate matrix polynomial dependencies. Several examples are presented (including an F-16 at an extreme flight condition, a missile model, and a generic example with numerous crossproduct terms), and comparisons are given with other LFT modeling tools that are currently available. The LFT modeling method and preliminary software tool presented in this paper are shown to compare favorably with these methods.

The vortex-induced angular accelerations experienced could be predicted within 30% by a mathematical upset response model when the characteristics of the wake were well represented by the vortex model. The vortex model used in the present study adequately represented the wake flow field when the vortices dissipated symmetrically and only one vortex pair existed in the wake.

    The Applied Physics Laboratory (APL) has developed a magnetometer instrument for a swedish satellite named Freja with launch scheduled for August 1992 on a Chinese Long March rocket. The magnetometer controller utilized a custom microprocessor designed at APL with the Genesil silicon compiler. The processor evolved from our experience with an older bit-slice design and two prior single chip efforts. The architecture of our microprocessor greatly lowered software development costs because it was optimized to provide an interactive and extensible programming environment hosted by the target hardware. Radiation tolerance of the microprocessor was also tested and was adequate for Freja's mission -- 20 kRad(Si) total dose and very infrequent latch-up and single event upset events.

    It was hypothesized that combined individual child vulnerability (anxious solitude) and interpersonal stress (peer exclusion) would predict the strongest responses to experimentally manipulated behavioral peer rejection. Results indicated that in a sample of 3rd graders (N = 160, 59% girls), anxious solitary excluded children displayed more behavioral manifestations of social helplessness before and after behavioral rejection, reported more feelings of rejection in anticipation of and reaction to behavioral rejection, and were observably more upset during behavioral rejection than were normative children. Moreover, affective responses to behavioral rejection mediated the relation between anxious solitary excluded status and behavioral manifestations of social helplessness. Furthermore, anxious solitary excluded children versus anxious solitary children demonstrated excessive suppression of vagal tone and more sustained acceleration in heart rate during the experiment. Results also indicated that affective, social-cognitive, and regulatory processes directly contributed to children's responses to behavioral rejection.

The two disturbances, which are most frequently encountered in water chemistry control practice, such as a breakdown or shutdown of temperature compensation during pH measurement and an increase in the heat-transfer fluid flow rate, have been modeled in the process of study. The study of the effect produced by the response characteristics of chemical control analyzers on the operation of a reagent dosing system under unsteady-state conditions is important for the operative control of a water chemistry regime state. The effect of temperature compensation during pH measurement on the dynamics of an ammonia-dosing system in the manual and automatic cycle chemistry control modes has been studied. It has been demonstrated that the reading settling time of a pH meter in the manual ammonia- dosing mode grows with a breakdown in temperature compensation and a simultaneous increase in the temperature of a heat-transfer fluid sample. To improve the efficiency of water chemistry control, some systems for the quality control of a heat-transfer fluid by a chemical parameter with the obligatory compensation of a disturbance in its flow rate have been proposed for use. Experimental results will possibly differ from industrial data due to a great length of sampling lines. For this reason, corrective reagent dosing systems must be adapted to the conditions of a certain power-generating unit in the process of their implementation.

    There is a growing consensus among pharmaceutical companies that more product and customer-specific approaches to marketing and selling a new drug can result in substantial increases in sales. Marketers and researchers taking a proactive micro-marketing approach to identifying, profiling, and communicating with target customers are likely to facilitate such approaches and outcomes. This article provides a working framework for creating customer databases that can be effectively mined to achieve a variety of such marketing and sales force objectives.

  11. Companies and the customers who hate them.

    PubMed

    McGovern, Gail; Moon, Youngme

    2007-06-01

    Why do companies bind customers with contracts, bleed them with fees, and baffle them with fine print? Because bewildered customers, who often make bad purchasing decisions, can be highly profitable. Most firms that profit from customers' confusion are on a slippery slope. Over time, their customer-centric strategies for delivering value have evolved into company-centric strategies for extracting it. Not surprisingly, when a rival comes along with a friendlier alternative, customers defect. Adversarial value-extracting strategies are common in such industries as cell phone service, retail banking, and health clubs. Overly complex product and pricing options, for example, may have been designed to serve various segments. But in fact they take advantage of how difficult it is for customers to predict their needs (such as how many cell phone minutes they'll use each month) and make it hard for them to choose the right product. Similarly, penalties and fees, which may have been instituted to offset the costs of undesirable customer behavior, like bouncing checks, turn out to be very profitable. As a result, companies have no incentive to help customers avoid them. Tactics like these generate bad publicity and fuel customer defections, creating opportunities for competitors. Virgin Mobile USA, for example, has lured millions of angry cell phone customers away from the incumbents by offering a straightforward plan with no hidden fees, no time-of-day restrictions, and no contracts. ING Direct, now the fourth-largest thrift bank in the United States, offers accounts with no fees, no tiered interest rates, and no minimums. In industries where squeezing value from customers is commonplace, companies that dismantle these harmful practices and design a transparent, value-creating offer can head off customer retaliation and spur rapid growth.

  12. Focusing on customer service.

    PubMed

    1996-01-01

    This booklet is devoted to a consideration of how good customer service in family planning programs can generate demand for products and services, bring customers back, and reduce costs. Customer service is defined as increasing client satisfaction through continuous concern for client preferences, staff accountability to clients, and respect for the rights of clients. Issues discussed include the introduction of a customer service approach and gaining staff commitment. The experience of PROSALUD in Bolivia in recruiting appropriate staff, supervising staff, soliciting client feedback, and marketing services is offered as an example of a successful customer service approach. The key customer service functions are described as 1) establishing a welcoming atmosphere, 2) streamlining client flow, 3) personalizing client services, and 4) organizing and providing clear information to clients. The role of the manager in developing procedures is explored, and the COPE (Client-Oriented Provider-Efficient) process is presented as a good way to begin to make improvements. Techniques in staff training in customer service include brainstorming, role playing, using case studies (examples of which are provided), and engaging in practice sessions. Training also leads to the development of effective customer service attitudes, and the differences between these and organizational/staff-focused attitudes are illustrated in a chart. The use of communication skills (asking open-ended questions, helping clients express their concerns, engaging in active listening, and handling difficult situations) is considered. Good recovery skills are important when things go wrong. Gathering and using client feedback is the next topic considered. This involves identifying, recording, and discussing customer service issues as well as taking action on these issues and evaluating the results. The booklet ends by providing a sample of customer service indicators, considering the maintenance of a

    Accidents attributable to in-flight loss of control are the primary cause for fatal commercial jet accidents worldwide. The National Aeronautics and Space Administration (NASA) conducted a literature review to determine and identify the quantitative standards for assessing upset recovery performance. This review contains current recovery procedures for both military and commercial aviation and includes the metrics researchers use to assess aircraft recovery performance. Metrics include time to first input, recognition time and recovery time and whether that input was correct or incorrect. Other metrics included are: the state of the autopilot and autothrottle, control wheel/sidestick movement resulting in pitch and roll, and inputs to the throttle and rudder. In addition, airplane state measures, such as roll reversals, altitude loss/gain, maximum vertical speed, maximum/minimum air speed, maximum bank angle and maximum g loading are reviewed as well.

    1991-01-01

    The cosmic ray environment in space can affect the operation of Integrated Circuit (IC) devices via the phenomenon of Single Event Upset (SEU). In particular, heavy ions passing through an IC can induce sufficient integrated current (charge) to alter the state of a bistable circuit, for example a memory cell. The SEU effect is studied in great detail in both static and dynamic memory devices, as well as microprocessors fabricated from bipolar, Complementary Metal Oxide Semiconductor (CMOS) and N channel Metal Oxide Semiconductor (NMOS) technologies. Each device/process reflects its individual characteristics (minimum scale geometry/process parameters) via a unique response to the direct ionization of electron hole pairs by heavy ion tracks. A summary of these analytical and experimental SEU investigations is presented.

    1994-11-01

    We prepared die-upset Nd-Fe-Co-B magnets from melt-spun ribbon powders which were a series of blends of two ribbon alloys. One alloy was always ternary Nd-Fe-B (no cobalt), and in the other cobalt replaced up to half of the iron. Differential scanning calorimeter measurements revealed that during hot working, the cobalt diffused across ribbon boundaries, effectively redistributing the transition metal concentration throughout the magnet. Instead of anomalies indicating the Curie temperatures of the two original ribbon compositions, we found a single transition consistent with the average cobalt concentration in the magnet. However, the transition was broader than expected, suggesting that the homogenization was incomplete. These results are new evidence of massive diffusion occurring between ribbons, changing the microstructure and facilitating the deformation of the otherwise rigid 2-14-1 magnet.

    During the course of 9{degree} tapered side-bonding resistance upset weld development at Mound, various studies have been conducted to evaluate the effect of yield strength on welds in 304L stainless steel. The results of these studies have concluded that at high yield strengths there may be a minor reduction in the length of Class 2 or better bond. Satisfactory welds have been produced with materials having yield strengths ranging from 36.0 to 141.0 ksi. However, when body yield strengths exceed 80.0 ksi a minor decrease in bond lengths begins. A significant inverse relationship between stem yield strength and bond length was shown to exist. 8 refs., 9 figs., 10 tabs.

    It is shown that single-event-upsets (SEUs) due to cosmic rays are a significant source of single bit error in spacecraft computers. The physical mechanism of SEU, electron hole generation by means of Linear Energy Transfer (LET), it discussed with reference made to the results of a study of the environmental effects on computer systems of the Galileo spacecraft. Techniques for making software more tolerant of cosmic ray effects are considered, including: reducing the number of registers used by the software; continuity testing of variables; redundant execution of major procedures for error detection; and encoding state variables to detect single-bit changes. Attention is also given to design modifications which may reduce the cosmic ray exposure of on-board hardware. These modifications include: shielding components operating in LEO; removing low-power Schottky parts; and the use of CMOS diodes. The SEU parameters of different electronic components are listed in a table.

    This study tested within-person associations between intoxication, negative affect, and self-control demands and two forms of self-control failure, interpersonal conflict, and neglecting responsibilities. Effortful control was hypothesised to act as a buffer, reducing individual susceptibility to these within-person effects. In contrast, reactivity was hypothesised to potentiate the within-person associations. 274 young adults aged 18–27 (56% women, 93% white) completed experience sampling assessments for up to 49 days over the course of 1.3 years. Results indicated independent within-person effects of intoxication, negative affect, and self-control demands on the outcomes. Hypothesised moderating effects of reactivity were not supported. Effortful control did not moderate the effects of self-control demands as expected. However, effortful control exhibited a protective effect when individuals were intoxicated or upset to reduce the likelihood of maladaptive behavioural outcomes. PMID:26264715

    Low earth orbit satellite and Jupiter orbiter probe semiconductor devices may incur soft errors or single event upsets, manifested as bit flips, during exposure to such nuclear particles or heavy ions as trapped protons with energies ranging up to 1000 MeV. Experimental data is given on the average proton fluence needed to cause a bit flip as a function of proton energy for isoplanar bipolar TTL RAMs. Error dependence data shape and threshold energy can be related to the existing body of theoretical data on energy deposition following proton nuclear reactions. Experimental data also show that the relative cross sectional amplitude for functionally identical devices can be related to the device's power consumption.

  4. Opinion Summarizationof CustomerComments

    NASA Astrophysics Data System (ADS)

    Fan, Miao; Wu, Guoshi

    Web 2.0 technologies have enabled more and more customers to freely comment on different kinds of entities, such as sellers, products and services. The large scale of information poses the need and challenge of automatic summarization. In many cases, each of the user-generated short comments implies the opinions which rate the target entity. In this paper, we aim to mine and to summarize all the customer comments of a product. The algorithm proposed in this researchis more reliable on opinion identification because it is unsupervised and the accuracy of the result improves as the number of comments increases. Our research is performed in four steps: (1) mining the frequent aspects of a product that have been commented on by customers; (2) mining the infrequent aspects of a product which have been commented by customers (3) identifying opinion words in each comment and deciding whether each opinion word is positive, negative or neutral; (4) summarizing the comments. This paper proposes several novel techniques to perform these tasks. Our experimental results using comments of a number of products sold online demonstrate the effectiveness of the techniques.

    A few high density UV-EPROM's (32Kb × 8) were irradiated with 5.41 MeV energy α-particles with fluences from 104 to 108 alphas/cm2 and 100 MeV nickel, iodine and silver ions for low fluences between 5 × 107 and 108 ions/cm2. The energy and ion species was selected on the basis of predicted threshold values of linear energy transfer (LET) in silicon. The program which was stored in the memory found to be changed from 0 to 1 and 1 to 0 state, respectively. On the basis of changed states, the cross-sections (σ) were calculated to investigate the single event effects/upsets. No upset was observed in case of α-particle since it has very low LET, but the SEU cross-section found to be more in case of Iodine i.e. 2.29 × 10-3 cm2 than that of nickel, 2.12 × 10-3 cm2 and silver, 2.26 × 10-3. This mainly attributes that LET for iodine is more as compared to silver and nickel ions, which deposits large amount of energy near the sensitive node of memory cell in the form of electron-hole pairs required to change the state. These measured SEU cross-section were also compared with theoretically predicted values along with the Weibull distribution fit to the ion induced experimental SEU data. The theoretical predicted SEU cross-section 3.27 × 10-3 cm2 found to be in good agreement with the measured SEU cross-section.

  6. Characterization of Inorganic Biocarriers That Moderate System Upsets during Fixed-Film Biotreatment Processes

    Inorganic matrices were developed for fixed-film bioreactors affording protection to microorganisms and preventing loss of bioreactor productivity during system upsets. These biocarriers, designated Type-Z, contain ion-exchange properties and possess high porosity and a high level of surface area, which provide a suitable medium for microbial colonization. Viable cell populations of 109/g were attainable, and scanning electron micrographs revealed extensive external colonization and moderate internal colonization with aerobic microorganisms. Laboratory-scale bioreactors were established with various biocarriers and colonized with Pseudomonas aeruginosa, and comparative studies were performed. The data indicated that bioreactors containing the Type-Z biocarriers were more proficient at removing phenol (1,000 ppm) than bioreactors established with Flexirings (plastic) and Celite R635 (diatomaceous earth) biocarriers. More significantly, these biocarriers were shown to moderate system upsets that affect operation of full-scale biotreatment processes. For example, subjecting the Type-Z bioreactor to an influent phenol feed at pH 2 for periods of 24 h did not decrease the effluent pH or reactor performance. In contrast, bioreactors containing either Celite or Flexirings demonstrated an effluent pH drop to ∼2.5 and a reduction in reactor performance by 75 to 82%. The Celite reactor recovered after 5 days, whereas the bioreactors containing Flexirings did not recover. Similar advantages were noted during either nutrient or oxygen deprivation experiments as well as alkali and organic system shocks. The available data suggest that Type-Z biocarriers represent an immobilization medium that provides an amenable environment for microbial growth and has the potential for improving the reliability of fixed-film biotreatment processes.

    PubMed

    Krestel, Ralf; Dokoohaki, Nima

    2015-06-01

    E-commerce Web sites owe much of their popularity to consumer reviews accompanying product descriptions. On-line customers spend hours and hours going through heaps of textual reviews to decide which products to buy. At the same time, each popular product has thousands of user-generated reviews, making it impossible for a buyer to read everything. Current approaches to display reviews to users or recommend an individual review for a product are based on the recency or helpfulness of each review. In this paper, we present a framework to rank product reviews by optimizing the coverage of the ranking with respect to sentiment or aspects, or by summarizing all reviews with the top-K reviews in the ranking. To accomplish this, we make use of the assigned star rating for a product as an indicator for a review's sentiment polarity and compare bag-of-words (language model) with topic models (latent Dirichlet allocation) as a mean to represent aspects. Our evaluation on manually annotated review data from a commercial review Web site demonstrates the effectiveness of our approach, outperforming plain recency ranking by 30% and obtaining best results by combining language and topic model representations.

    Every company makes choices about the channels it will use to go to market. Traditionally, the decision to sell through a discount superstore or a pricey boutique, for instance, was guided by customer demographics. A company would identify a target segment of buyers and go with the channel that could deliver them. It was a fair assumption that certain customer types were held captive by certain channels--if not from cradle to grave, then at least from initial consideration to purchase. The problem, the authors say, is that today's customers have become unfettered. As their channel options have proliferated, they've come to recognize that different channels serve their needs better at different points in the buying process. The result is "value poaching." For example, certain channels hope to use higher margin sales to cover the cost of providing expensive high-touch services. Potential customers use these channels to do research, then leap to a cheaper channel when it's time to buy. Customers now hunt for bargains more aggressively; they've become more sophisticated about how companies market to them; and they are better equipped with information and technology to make advantageous decisions. What does this mean for your go-to-market strategy? The authors urge companies to make a fundamental shift in mind-set toward designing for buyer behaviors, not customer segments. A company should design pathways across channels to help its customers get what they need at each stage of the buying process--through one channel or another. Customers are not mindful of channel boundaries--and you shouldn't be either. Instead, they are mindful of the value of individual components in your channels--and you should be, too.

    2012-01-01

    Militarized versions of commercial platforms are growing in popularity due to many logistical benefits in the form of commercial off-the-shelf (COTS) parts, established production methods, and commonality for different certifications. Commercial data and best practices are often leveraged to reduce procurement and engineering development costs. While the developmental and cost reduction benefits are clear, these militarized aircraft are routinely operated in flight at significantly different conditions and in significantly different manners than for routine commercial flight. Therefore they are at a higher risk of flight envelope exceedance. This risk may lead to departure from controlled flight and/or aircraft loss1. Historically, the risk of departure from controlled flight for military aircraft has been mitigated by piloted simulation training and engineering analysis of typical aircraft response. High-agility military aircraft simulation databases are typically developed to include high angles of attack (AoA) and sideslip due to the dynamic nature of their missions and have been developed for many tactical configurations over the previous decades. These aircraft simulations allow for a more thorough understanding of the vehicle flight dynamics characteristics at high AoA and sideslip. In recent years, government sponsored research on transport airplane aerodynamic characteristics at high angles of attack has produced a growing understanding of stall/post-stall behavior. This research along with recent commercial airline training initiatives has resulted in improved understanding of simulator-based training requirements and simulator model fidelity.2-5 In addition, inflight training research over the past decade has produced a database of pilot performance and recurrency metrics6.

    Preliminary data analysis for a physical fault injection experiment of a digital system exposed to High Intensity Radiated Fields (HIRF) in an electromagnetic reverberation chamber suggests a direct causal relation between the time profile of the field strength amplitude in the chamber and the severity of observed effects at the outputs of the radiated system. This report presents an analysis of the field strength modulation induced by the movement of the field stirrers in the reverberation chamber. The analysis is framed as a characterization of the discrete features of the field strength waveform responsible for the faults experienced by a radiated digital system. The results presented here will serve as a basis to refine the approach for a detailed analysis of HIRF-induced upsets observed during the radiation experiment. This work offers a novel perspective into the use of an electromagnetic reverberation chamber to generate upset-inducing stimuli for the study of fault effects in digital systems.

    This paper describes the possibility of a switching upset of a magnetic tunnel junction (MTJ) caused by a terrestrial radiation-induced single-event-upset (SEU) current in spintronic integrated circuits. The current waveforms were simulated by using a 3-D device simulator in a basic circuit including MTJs designed using 90-nm CMOS parameters and design rules. The waveforms have a 400 -μA peak and a 200-ps elapsed time when neutron particles with a linear energy transfer value of 14 MeV cm{sup 2}/mg enter the silicon surface. The authors also found that the SEU current may cause soft errors with a probability of more than 10{sup −12} per event, which was obtained by approximate solution of the ordinary differential equation of switching probability when the intrinsic critical current (I{sub C0}) became less than 30 μA.

    Transmission electron microscopy (TEM) was used to characterize the microstructures at and near the weld interface in upset welded Type 304L stainless steel test samples. Two sample configurations were examined in this study; upset welded cylinders prepared using a commercial resistance welder and cylindrical shaped samples welded in a Gleeble 1500 thermomechanical simulation device. The Gleeble samples evaluated were welded at 800 C, 900 C and 1,200 C with a 0.5 cm weld upset. The base microstructure of the samples varied with weld temperature. The lower temperature specimens contained a large free-dislocation density and distinct dislocation cells. The higher temperature specimens contained well-developed subgrains and a much lower free-dislocation density. The microstructure of the upset welded samples most closely resembled the 1,200 C Gleeble sample. No distinct bond line was observed by TEM in any of the specimens, i.e., diffusion and grain growth occurred across all weld interfaces. However, weld interfaces in both specimen configurations were characterized by the presence of 50--300 nm diameter particles spaced between 300 and 1,300 nm apart. Through the use of electron diffraction analysis and X-ray microanalysis two precipitate types were identified in both specimen configurations. A crystalline phase very similar to Mn{sub 1.5}Cr{sub 1.5}O{sub 4} and an amorphous phase enriched mainly in Si and Al were observed. Surface oxides and/or internal impurities may be sources for these precipitates. Future work will include a controlled study designed to determine the origin of the interface precipitates.

  13. Real-time closed-loop simulation and upset evaluation of control systems in harsh electromagnetic environments

    Digital control systems for applications such as aircraft avionics and multibody systems must maintain adequate control integrity in adverse as well as nominal operating conditions. For example, control systems for advanced aircraft, and especially those with relaxed static stability, will be critical to flight and will, therefore, have very high reliability specifications which must be met regardless of operating conditions. In addition, multibody systems such as robotic manipulators performing critical functions must have control systems capable of robust performance in any operating environment in order to complete the assigned task reliably. Severe operating conditions for electronic control systems can result from electromagnetic disturbances caused by lightning, high energy radio frequency (HERF) transmitters, and nuclear electromagnetic pulses (NEMP). For this reason, techniques must be developed to evaluate the integrity of the control system in adverse operating environments. The most difficult and illusive perturbations to computer-based control systems that can be caused by an electromagnetic environment (EME) are functional error modes that involve no component damage. These error modes are collectively known as upset, can occur simultaneously in all of the channels of a redundant control system, and are software dependent. Upset studies performed to date have not addressed the assessment of fault tolerant systems and do not involve the evaluation of a control system operating in a closed-loop with the plant. A methodology for performing a real-time simulation of the closed-loop dynamics of a fault tolerant control system with a simulated plant operating in an electromagnetically harsh environment is presented. In particular, considerations for performing upset tests on the controller are discussed. Some of these considerations are the generation and coupling of analog signals representative of electromagnetic disturbances to a control system under test

    An apparatus for and method of eliminating single event upsets (or SEU) in combinational logic are used to prevent error propagation as a result of cosmic particle strikes to the combinational logic. The apparatus preferably includes a combinational logic block electrically coupled to a delay element, a latch and an output buffer. In operation, a signal from the combinational logic is electrically coupled to a first input of the latch. In addition, the signal is routed through the delay element to produce a delayed signal. The delayed signal is routed to a second input of the latch. The latch used in the apparatus for preventing SEU preferably includes latch outputs and a feature that the latch outputs will not change state unless both latch inputs are correct. For example, the latch outputs may not change state unless both latch inputs have the same logical state. When a cosmic particle strikes the combinational logic, a transient disturbance with a predetermined length may appear in the signal. However, a function of the delay element is to preferably provide a time delay greater than the length of the transient disturbance. Therefore, the transient disturbance will not reach both latch inputs simultaneously. As a result, the latch outputs will not permanently change state in error due to the transient disturbance. In addition, the output buffer preferably combines the latch outputs in such a way that the correct state is preserved at all times. Thus, combinational logic with protection from SEU is provided.

    Effects of welding current (at the range of 2-4 kA) on the microstructure and mechanical properties of upset resistance welds of AISI-1035 carbon steel to AISI-304L austenitic stainless steel rods were investigated. The results showed that the joint strength first increased by raising the welding current up to 3 kA and then decreased beyond it. Increasing trend was related to more plastic deformation, accelerated diffusion, reduction of defects and formation of mechanical locks at the joint interface. For currents more than 3 kA, decrease in the joint strength was mainly caused by formation of hot spots. Using the optimum welding current of 3 kA, tensile strength of the joint reached to 76% of the carbon steel base metal strength. Microstructural observations and microhardness results confirmed that there was no hard phase, i.e., martensite or bainite, at the weld zone. Moreover, a fully austenitic transition layer related to carbon diffusion from carbon steel was observed at the weld interface.

    A delay circuit includes a first network having an input and an output node, a second network having an input and an output, the input of the second network being coupled to the output node of the first network. The first network and the second network are configured such that: a glitch at the input to the first network having a length of approximately one-half of a standard glitch time or less does not cause tile voltage at the output of the second network to cross a threshold, a glitch at the input to the first network having a length of between approximately one-half and two standard glitch times causes the voltage at the output of the second network to cross the threshold for less than the length of the glitch, and a glitch at the input to the first network having a length of greater than approximately two standard glitch times causes the voltage at the output of the second network to cross the threshold for approximately the time of the glitch. A method reduces the vulnerability of a latch to single event upsets. The latch includes a gate having an input and an output and a feedback path from the output to the input of the gate. The method includes inserting a delay into the feedback path and providing a delay in the gate.

    Preferred orientations in polycrystalline materials can significantly affect their physical and mechanical response through the retention of anisotropic properties inherent to the single crystal. In this study the texture evolution in upset-forged PIM and wrought tantalum was measured as a function of initial texture, compressive strain, and relative position in the pressing. A <001>/<111> duplex fiber texture parallel to the compression axis was generally observed, with varying degrees of a radial component evident in the wrought material. The development of deformation textures derives from restricted crystallographic slip conditions that generate lattice rotations, and these grain reorientations can be modeled as a function of the prescribed deformation gradient. Texture development was simulated for equivalent deformations using both a modified Taylor approach and a viscoplastic self-consistent (VPSC) model. A comparison between the predicted evolution and experimental results shows a good correlation with the texture components, but an overly sharp prediction at large strains from both the Taylor and VPSC models.

    Field-programmable gate arrays are well-suited to DSP and digital communications applications. SRAM-based FPGAs, however, are susceptible to radiation-induced single-event upsets (SEUs) when deployed in space environments. These effects are often handled with the area and power-intensive TMR mitigation technique. This paper evaluates the effects of SEUs in the FPGA configuration memory as noise in a digital filter, showing that many SEUs in a digital communications system cause effects that could be considered noise rather than circuit failure. Since DSP and digital communications applications are designed to withstand certain types of noise, SEU mitigation techniques that are less costly than TMR may be applicable. This could result in large savings in area and power when implementing a reliable system. Our experiments show that, of the SEUs that affected the digital filter with a 20 dB SNR input signal, less than 14% caused an SNR loss of more than 1 dB at the output.

    Single event upsets (SEU) occur when a single ionizing particle such as a cosmic ray passes through a microelectronic device, causing a random change in the logic state of a bistable circuit. The SEU phenomenon is of great interest since it is a source of errors and failures, notably on spaceborne microelectronic chips. A Van de Graaff accelerator was used to simulate the cosmic ray heavy ion linear energy transfer (LET) distribution found in earth orbit, and accelerator experiments were conducted in a dedicated facility for SEU testing of microelectronic devices. The first set of experiments set out to compare data obtained by two different SEU memory tester systems, and a second set attempted to compare data obtained using ions of different species and energy but the same LET, and to determine the accuracy of the concept of a constant SEU cross-section for a given LET. Observation of a fluence dependent SEU cross section and transient behavior led to a third set of experiments, designed to allow observation in more detail of the dynamics of these newly observed phenomena. The charge collection efficiency of detectors to high LET ions was also measured.

  1. Smart customers, dumb companies.

    Locke, C

    Customers today are being bombarded with an overwhelming array of choices. To alleviate customer frustration, say Steven Cristol and Peter Sealey in Simplicity Marketing, companies should stop creating new brands and product extensions. Better to consolidate product and service functions by following a four R approach: replace, repackage, reposition, and replenish. That's an outmoded, dictatorial view of markets, says Christopher Locke. Far from being stymied by choices, customers are rapidly becoming smarter than the companies that pretend to serve them. In this networked economy, people are talking among themselves, and that changes everything. Locke predicts we'll see a growing number of well-defined micromarkets--groups of customers converging in real time around entertaining and knowledgeable voices--such as NPR's car guys and the Motley Fool investment site. "Micromedia" Web sites will replace traditional advertising because they'll provide credible user-supplied news about products and services. Locke contends that an open exchange of information solves the "problem" of choice much better than manipulative strategies like simplicity or even permission marketing. Companies can participate in micromarkets through what Locke dubs "gonzo marketing." If Ford, for example, discovers that a subset of its employees are organic gardeners, it may offer support to a big independent organic-gardening Web site with donations and employee volunteers. This marketing effort would be driven not by advertising managers but by people with genuine interest in each micromarket, so it would have credibility with customers. With gonzo marketing, both companies and their markets will benefit.

    Chromatin plays a critical role in faithful implementation of gene expression programs. Different post-translational modifications (PTMs) of histone proteins reflect the underlying state of gene activity, and many chromatin proteins write, erase, bind, or are repelled by, these histone marks. One such protein is UpSET, the Drosophila homolog of yeast Set3 and mammalian KMT2E (MLL5). Here, we show that UpSET is necessary for the proper balance between active and repressed states. Using CRISPR/Cas-9 editing, we generated S2 cells that are mutant for upSET. We found that loss of UpSET is tolerated in S2 cells, but that heterochromatin is misregulated, as evidenced by a strong decrease in H3K9me2 levels assessed by bulk histone PTM quantification. To test whether this finding was consistent in the whole organism, we deleted the upSET coding sequence using CRISPR/Cas-9, which we found to be lethal in both sexes in flies. We were able to rescue this lethality using a tagged upSET transgene, and found that UpSET protein localizes to transcriptional start sites (TSS) of active genes throughout the genome. Misregulated heterochromatin is apparent by suppressed position effect variegation of the wm4 allele in heterozygous upSET-deleted flies. Using nascent-RNA sequencing in the upSET-mutant S2 lines, we show that this result applies to heterochromatin genes generally. Our findings support a critical role for UpSET in maintaining heterochromatin, perhaps by delimiting the active chromatin environment. PMID:28064188

    Retaining existing customer is a major task for many companies because cost to acquire new customers is higher than retaining existing customers. For mortgage business in Bank X, customer relationship management plays a big role to understand their customers' profile and churners so that suitable action can be done to retain their potential churners. Objectives of this study are (1) understanding their customers' profile and churners, (2) modeling potential churners using neural network model and (3) to deploy the model to identify potential churners. Data was divided into two parts: sampling (67,470 cases) and scoring (4,488 cases). Analysis was done using SAS Enterprise Miner. Dependent variable is churner/non churner while independent variables are balance and amount of loan, interest rate offered installment amount, loan performance, months in arrear, vintage, tenure, age, race and gender. Potential churners were identified as Malays, followed by Indian, other races and Chinese. Nonperforming loan and male customers tend to churn compared to performing loan and female customers. Younger customers with small loan amount, balance and monthly instalment, higher interest rate, have many months in arrears, longer vintage and tenure have higher tendency to churn from Bank X. Hence, Bank X should focus on the potential churners for their campaign to minimize the expenses of retaining existing customers by doing an effective campaign with high successful rate.

  13. Against customer service.

    PubMed

    Trotter, G

    1998-01-01

    This essay examines the nature of service in medicine and the relationship between service and profit. "Customer service medicine" is identified with the interrelated views that 1) profit is or ought to be healthcare's fundamental concern and 2) the quality of medical service corresponds to the degree to which it produces a feeling of approval in patients. This position is contrasted with the more traditional "beneficence model," which holds that 1) service ought to be healthcare's fundamental concern and 2) the proper criterion of quality medical service is the alleviation, mitigation, or prevention of the human suffering that occasions illness. Five shortcomings in the customer service model are identified: 1) customer service advocates often appeal to an unsound "efficiency argument"; 2) the prioritization of profit over service will vitiate patients' legitimate trust in healthcare; 3) the prioritization of profit converts medicine from a "practice" into an "instrumental activity"; 4) the prioritization of profit countervails the values of continuity and thoroughness; and 5) the notion of service as customer satisfaction derives more from the exigencies of turning a profit than from an analysis of sick persons' needs.

    This report is the third in a series of analyses written in support of a plan to revise the Hanford Waste Treatment and Immobilization Plant (WTP) Preliminary Criticality Safety Evaluation Report (CSER) that is being implemented at the request of the U.S. Department of Energy (DOE) Criticality Safety Group. A report on the chemical disposition of plutonium in Hanford tank wastes was prepared as Phase 1 of this plan (Delegard and Jones 2015). Phase 2 is the provision of a chemistry report to describe the potential impacts on criticality safety of waste processing operations within the WTP (Freer 2014). In accordance with the request from the Environmental and Nuclear Safety Department of the WTP (Miles and Losey 2012), the Phase 2 report assessed the potential for WTP process conditions within and outside the range of normal control parameters to change the ratio of fissile material to neutron-absorbing material in the waste as it is processed with an eye towards potential implications for criticality safety. The Phase 2 study also considered the implications should WTP processes take place within the credible range of chemistry upset conditions. In the present Phase 3 report, the 28 phenomena described in the Phase 2 report were considered with respect to the disposition of plutonium and various absorber elements. The phenomena identified in the Phase 2 report are evaluated in light of the Phase 1 report and other resources to determine the impacts these phenomena might have to alter the plutonium/absorber dispositions and ratios. The outcomes of the Phase 3 evaluations then can be used to inform subsequent engineering decisions and provide reasonable paths forward to mitigate or overcome real or potential criticality concern in plant operations.

    In this paper, we report the use of an NIR fiber-optic spectrometer with a high-speed diode array for calibration-free monitoring and modeling of the reaction of acetic anhydride with butanol using the catalyst 4-(dimethylamino)pyridine in a microscale batch reactor. Acquisition of spectra at 5 ms/scan gave information relevant for modeling these fast batch processes with a single multibatch kinetic model. Nonlinear fitting of a first-principles model directly to the reaction spectra gave calibration-free estimates of time-dependent concentration profiles and pure component spectra. The amount of catalyst was varied between different batches to permit accurate estimation of its effect in the multiway model. A wide range of different models with increasing complexity could be fit to each batch individually with low residuals and apparent low lack of fit. However, only one model properly estimated the concentration profiles when all five batches were fitted simultaneously in a multiway kinetic model. Inclusion of on-line temperature measurements and use of an Arrhenius model for the estimated rate constant gave significantly improved model fits compared to an isothermal kinetic model. Augmentation of prerun batches with data from an additional batch permitted model-based forecasts of reaction trajectories, reaction yield, reaction end points, and process upsets. One batch with added water to simulate a process upset was easily detected by the calibration free process model.

    Purpose: To compare the dose distribution between customized planning (CP) and adopting a single plan (SP) in multifractionated high-dose-rate brachytherapy and to establish predictors for the necessity of CP in a given patient. Methods and Materials: A total of 50 computed tomography-based plans for 10 patients were evaluated. Each patient had received 6 Gy for five fractions. The clinical target volume and organs at risk (i.e., rectum, bladder, sigmoid, and small bowel) were delineated on each computed tomography scan. For the SP approach, the same dwell position and time was used for all fractions. For the CP approach, the dwell position and time were reoptimized for each fraction. Applicator position variation was determined by measuring the distance between the posterior bladder wall and the tandem at the level of the vaginal fornices. Results: The organs at risk D{sub 2cc} (dose to 2 cc volume) was increased with the SP approach. The dose variation was statistically similar between the tandem and ring and tandem and ovoid groups. The bladder D{sub 2cc} dose was 81.95-105.42 Gy{sub 2} for CP and 82.11-122.49 Gy{sub 2} for SP. In 5 of the 10 patients, the bladder would have been significantly overdosed with the SP approach. The variation of the posterior bladder wall distance from that in the first fraction was correlated with the increase in the bladder D{sub 2cc} (SP/CP), with a correlation coefficient of -0.59. Conclusion: Our results support the use of CP instead of the SP approach to help avoid a significant overdose to the bladder. This is especially true for a decrease in the posterior wall distance of {>=}0.5 cm compared with that in the first fraction.

    Within the biomedical area over one hundred terminologies exist and are merged in the Unified Medical Language System Metathesaurus, which gives over 1 million concepts. When such huge terminological resources are available, the users must deal with them and specifically they must deal with irrelevant parts of these terminologies. We propose to exploit seed terms and semantic distance algorithms in order to customize the terminologies and to limit within them a semantically homogeneous space. An evaluation performed by a medical expert indicates that the proposed approach is relevant for the customization of terminologies and that the extracted terms are mostly relevant to the seeds. It also indicates that different algorithms provide with similar or identical results within a given terminology. The difference is due to the terminologies exploited. A special attention must be paid to the definition of optimal association between the semantic similarity algorithms and the thresholds specific to a given terminology.

    This effort represents a contribution to the wider distributed energy resources (DER) research of the Consortium for Electric Reliability Technology Solutions (CERTS, http://certs.lbl.gov) that is intended to attack and, hopefully, resolve the technical barriers to DER adoption, particularly those that are unlikely to be of high priority to individual equipment vendors. The longer term goal of the Berkeley Lab effort is to guide the wider technical research towards the key technical problems by forecasting some likely patterns of DER adoption. In sharp contrast to traditional electricity utility planning, this work takes a customer-centric approach and focuses on DER adoption decision making at, what we currently think of as, the customer level. This study reports on Berkeley Lab's second year effort (completed in Federal fiscal year 2000, FY00) of a project aimed to anticipate patterns of customer adoption of distributed energy resources (DER). Marnay, et al., 2000 describes the earlier FY99 Berkeley Lab work. The results presented herein are not intended to represent definitive economic analyses of possible DER projects by any means. The paucity of data available and the importance of excluded factors, such as environmental implications, are simply too important to make such an analysis possible at this time. Rather, the work presented represents a demonstration of the current model and an indicator of the potential to conduct more relevant studies in the future.

    The community medical center is the first barrier for lipid control. We aimed to survey the residents' cholesterol condition in the community, and pursue the reasons for the upsetting results from various aspects. Residents and physicians were recruited from four community centers. Residents completed questionnaires and a physical examination as well as biochemical analysis. Physicians were also asked to complete a questionnaire, some of which were about basic knowledge of lipids. About 37.0% male and 48.1% female had elevated cholesterol levels. Residents' blood pressure (BP), fasting glucose (FG), body mass index (BMI), and waist circumference (WC) were positively associated with their low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC). Framingham risk scoring (FRS) was strongly related to cholesterol (P < 0.001 for LDL-C and TC). Residents' higher education grade was positively related to a normal cholesterol condition (P < 0.001), while personal income was negatively related to it. Rural residents had higher percent of population with normal cholesterol level (normal cholesterol rate) than their city counterpart (P < 0.001). Although physicians with college education had a much higher lipid knowledge level themselves, the physicians' factors had almost no relationship with the residents' cholesterol levels. Management of hypercholesterolemia should be an important component of health strategy in Beijing. Education is imperative for residents as well as for physicians.

    Zoutendyk, John A. (Inventor)

    1991-01-01

    Bipolar transistors fabricated in separate buried layers of an integrated circuit chip are electrically isolated with a built-in potential barrier established by doping the buried layer with a polarity opposite doping in the chip substrate. To increase the resistance of the bipolar transistors to single-event upsets due to ionized particle radiation, the substrate is biased relative to the buried layer with an external bias voltage selected to offset the built-in potential just enough (typically between about +0.1 to +0.2 volt) to prevent an accumulation of charge in the buried-layer-substrate junction.

    Single-Event Upset (SEU) response of a bipolar low-power Schottky-diode-clamped TTL static RAM has been observed using Br ions in the 100-240 MeV energy range and O ions in the 20-100 MeV range. These data complete the experimental verification of circuit-simulation SEU modeling for this device. The threshold for onset of SEU has been observed by the variation of energy, ion species and angle of incidence. The results obtained from the computer circuit-simulation modeling and experimental model verification demonstrate a viable methodology for modeling SEU in bipolar integrated circuits.

    Single-Event Upset (SEU) in bipolar integrated circuits (ICs) is caused by charge collection from ion tracks in various regions of a bipolar transistor. This paper presents experimental data which have been obtained wherein the range-energy characteristics of heavy ions (Br) have been utilized to determine the cross section for soft-error generation as a function of charge collected from single-particle tracks which penetrate a bipolar static RAM. The results of this work provide a basis for the experimental verification of circuit-simulation SEU modeling in bipolar ICs.

    Single-event upset effects from heavy ions are measured for Motorola silicon-on-insulator (SOI) microprocessor with 90 nm feature sizes. The results are compared with previous results for SOI microprocessors with feature sizes of 130 and 180 nm. The cross section of the 90 nm SOI processors is smaller than results for 130 and 180 nm counterparts, but the threshold is about the same. The scaling of the cross section with reduction of feature size and core voltage for SOI microprocessors is discussed.

    This presentation discusses advantages and best practices for incorporating magnesium in automotive component applications to achieve substantial mass reduction, as well as some of the key challenges with respect to joining, coating, and galvanic corrosion, before providing an introduction and status update of the U.S. Department of Energy and Department of Defense jointly sponsored Upset Protrusion Joining (UPJ) process development and evaluation project. This update includes sharing performance results of a benchmark evaluation of the self-pierce riveting (SPR) process for joining dissimilar magnesium (Mg) to aluminum (Al) materials in four unique coating configurations before introducing the UPJ concept and comparing performance results of the joints made with the UPJ process to those made with the SPR process. Key results presented include: • The benchmark SPR process can produce good joints in the MgAM60B-Al 6013 joint configuration with minimal cracking in the Mg coupons if the rivet is inserted from the Mg side into the Al side. • Numerous bare Mg to bare Al joints made with the SPR process separated after only 6-wks of accelerated corrosion testing due to fracture of the rivet as a result of hydrogen embrittlement • For the same joint configurations, UPJ demonstrated substantially higher pre-corrosion joint strengths and post-corrosion joint strengths, primarily because of the larger diameter protrusion compared to smaller SPR rivet diameter and reduced degradation due to accelerated corrosion exposure • As with the SPR process, numerous bare Mg to bare Al joints made with the UPJ process also separated after 6-wks of accelerated corrosion testing, but unlike the SPR experience, the UPJ joints experienced degradation of the boss and head because of galvanic corrosion of the Mg casting, not hydrogen embrittlement of the steel rivet. • In the configuration where both the Mg and Al were pretreated with Alodine 5200 prior to joining and the complete

  13. FinFET memory cell improvements for higher immunity against single event upsets

    NASA Astrophysics Data System (ADS)

    Sajit, Ahmed Sattar

    The 21st century is witnessing a tremendous demand for transistors. Life amenities have incorporated the transistor in every aspect of daily life, ranging from toys to rocket science. Day by day, scaling down the transistor is becoming an imperious necessity. However, it is not a straightforward process; instead, it faces overwhelming challenges. Due to these scaling changes, new technologies, such as FinFETs for example, have emerged as alternatives to the conventional bulk-CMOS technology. FinFET has more control over the channel, therefore, leakage current is reduced. FinFET could bridge the gap between silicon devices and non-silicon devices. The semiconductor industry is now incorporating FinFETs in systems and subsystems. For example, Intel has been using them in their newest processors, delivering potential saving powers and increased speeds to memory circuits. Memory sub-systems are considered a vital component in the digital era. In memory, few rows are read or written at a time, while the most rows are static; hence, reducing leakage current increases the performance. However, as a transistor shrinks, it becomes more vulnerable to the effects from radioactive particle strikes. If a particle hits a node in a memory cell, the content might flip; consequently, leading to corrupting stored data. Critical fields, such as medical and aerospace, where there are no second chances and cannot even afford to operate at 99.99% accuracy, has induced me to find a rigid circuit in a radiated working environment. This research focuses on a wide spectrum of memories such as 6T SRAM, 8T SRAM, and DICE memory cells using FinFET technology and finding the best platform in terms of Read and Write delay, susceptibility level of SNM, RSNM, leakage current, energy consumption, and Single Event Upsets (SEUs). This research has shown that the SEU tolerance that 6T and 8T FinFET SRAMs provide may not be acceptable in medical and aerospace applications where there is a very high

    Conventional wisdom holds that the best customers and prospects for managed care are the healthiest consumers. This is true only because of the meager extent to which premiums can be adjusted for varying risk among individuals. If a decent health/risk adjustment system were used, the best consumers for managed care to go after would be the highest-risk, highest users of health care, provided only that risk and use can be improved. The healthiest consumers have both the least potential for improvement and the least reasons for loyalty.

  1. The mismanagement of customer loyalty.

    PubMed

    Reinartz, Werner; Kumar, V

    2002-07-01

    Who wouldn't want loyal customers? Surely they should cost less to serve, they'd be willing to pay more than other customers, and they'd actively market your company by word of mouth, right? Maybe not. Careful study of the relationship between customer loyalty and profits plumbed from 16,000 customers in four companies' databases tells a different story. The authors found no evidence to support any of these claims. What they did find was that the link between customers and profitability was more complicated because customers fall into four groups, not two. Simply put: Not all loyal customers are profitable, and not all profitable customers are loyal. Traditional tools for segmenting customers do a poor job of identifying that latter group, causing companies to chase expensively after initially profitable customers who hold little promise of future profits. The authors suggest an alternative approach, based on well-established "event-history modeling" techniques, that more accurately predicts future buying probabilities. Armed with such a tool, marketers can correctly identify which customers belong in which category and market accordingly. The challenge in managing customers who are profitable but disloyal--the "butterflies"--is to milk them for as much as you can while they're buying from you. A softly-softly approach is more appropriate for the profitable customers who are likely to stay loyal--your "true friends." As for highly loyal but not very profitable customers--the "barnacles"--you need to find out if they have the potential to spend more than they currently do. And, of course, for the "strangers"--those who generate no loyalty and no profits--the answer is simple: Identify early and don't invest anything.

  2. Feasibility of a neutron detector-dosemeter based on single-event upsets in dynamic random-access memories.

    2002-01-01

    The feasibility was investigated of a solid-state neutron detector/dosemeter based on single-event upset (SEU) effects in dynamic random-access memories (DRAMs), commonly used in computer memories. Such a device, which uses a neutron converter material to produce a charged particle capable of causing an upset, would be light-weight, low-power, and could be read simply by polling the memory for bit flips. It would have significant advantages over standard solid-state neutron dosemeters which require off-line processing for track etching and analysis. Previous efforts at developing an SEU neutron detector/dosemeter have suffered from poor response, which can be greatly enhanced by selecting a modern high-density DRAM chip for SEU sensitivity and by using a thin 10B film as a converter. Past attempts to use 10B were not successful because the average alpha particle energy was insufficient to penetrate to the sensitive region of the memory. This can be overcome by removing the surface passivation layer before depositing the 10B film or by implanting 10B directly into the chip. Previous experimental data show a 10(3) increase in neutron sensitivity by chips containing borosilicate glass, which could be used in an SEU detector. The results are presented of simulations showing that the absolute efficiency of an SEU neutron dosemeter can be increased by at least a factor of 1000 over earlier designs.

    Nd-Fe-B-type die-upset magnet with high electrical resistivity was prepared by doping of eutectic DyF3-LiF salt mixture. Mixture of melt-spun Nd-Fe-B flakes (MQU-F: Nd13.6Fe73.6Co6.6Ga0.6B5.6) and eutectic binary (DyF3-LiF) salt (25 mol% DyF3 - 75 mol% LiF) was hot-pressed and then die-upset. By adding the eutectic salt mixture (> 4 wt%), electrical resistivity of the die-upset magnet was enhanced to over 400 μ Ω .cm compared to 190 μ Ω .cm of the un-doped magnet. Remarkable enhancement of the electrical resistivity was attributed to homogeneous and continuous coverage of the interface between flakes by the easily melted eutectic salt dielectric mixture. It was revealed that active substitution of the Nd atoms in neighboring flakes by the Dy atoms from the added (DyF3-LiF) salt mixture had occurred during such a quick thermal processing of hot-pressing and die-upsetting. This Dy substitution led to coercivity enhancement in the die-upset magnet doped with the eutectic (DyF3-LiF) salt mixture. Coercivity and remanence of the die-upset magnet doped with (DyF3-LiF) salt mixture was as good as those of the DyF3-doped magnet.

    capacities on the candidate media; however, equilibrium testing does not provide information on the exchange kinetics and the shape of the packed column breakthrough isotherm. The performance of the most promising of the pre-screened media was then further tested and validated at the NPP site, using small packed bed columns containing the media to be evaluated, with use of actual NPP waste water under dynamic flow conditions. In the cited example, dynamic flow testing validated the performance characteristics for the most promising media, as previously-selected by the laboratory batch testing. In particular, it revealed that two novel media were particularly useful under process upset conditions, viz., AGC-5860 (a chemically modified activated carbon) for chelated transition metals (especially Co{sup 58} and 60), and ASM{sup 125} (a highly selective and tenacious resin product) especially for Sb{sup 125}. Subsequently, two of the most effective novel media identified in the screening effort have now been deployed at full-scale at an NPP site for the duration of approximately one year (to-date). The antimony-selective resin has performed especially well, greatly outperforming and outlasting previously utilized media, under many variations in the NPP influent waste water composition (including outage conditions and high boron concentrations, etc.). It was further found that the ASM 125 ISM had an excellent affinity for tellurium (Te{sup 125m}), a daughter of antimony (Sb). (See data from Exelon's Byron Station. Also, on-going at Calvert Cliffs). At the request of two other NPPs (STP and Calvert Cliffs), the AGC ISM was found to solve their Fe 55 and Ni 63 problem, likely resulting from steam generator change outs at the plants. Lastly, work is on-going remove radioactive iodine (I{sup 129}) with the granulated AGC. (authors)

    With the coming of age of web as a mainstream customer service channel, B2C companies have invested substantial resources in enhancing their web presence. Today customers can interact with a company, not only through the traditional phone channel but also through chat, email, SMS or web self-service. Each of these channels is best suited for some services and ill-matched for others. Customer service organizations today struggle with the challenge of delivering seamlessly integrated services through these different channels. This paper will evaluate some of the key challenges in multi-channel customer service. It will address the challenge of creating the right channel mix i.e. providing the right choice of channels for a given customer/behavior/issue profile. It will also provide strategies for optimizing the performance of a given channel in creating the right customer experience.

    The authors proposed and tested a model describing the relationship between customer service providers' perceptions and attitudes toward their service-related duties and their customers' perceptions of satisfaction with their service experiences. Results indicated that the perception of having standards for service delivery in an organization is strongly related to line-level employees' perceptions of support from coworkers and supervisors. Perceived support from coworkers was significantly related to service providers' customer orientation, whereas perceived support from supervisors showed a weaker relationship to a customer orientation. Ultimately, service providers' customer orientation was strongly related to customers' satisfaction with service. Finally, a set of post hoc analyses indicated that coworker and supervisory support explained a greater proportion of incremental variance in the model than did perceived organizational support alone.

    Viewing individuals in need of NHS care as customers has the potential to refocus the way their care is delivered. This article highlights some of the benefits of reframing the nurse-patient relationship in terms of customer care, and draws parallels between good customer care and the provision of high quality patient care in the NHS. It explores lessons to be learned from those who have studied the customer experience, which can be adapted to enhance the customer care experience within the health service. Developing professional expertise in the knowledge and skills that underpin good-quality interpersonal encounters is essential to improve the customer experience in health care and should be prioritised alongside the development of more technical skills. Creating a culture where emotional intelligence, caring and compassion are essential requirements for all nursing staff will improve patient satisfaction.

    Utilizing the comment section of patient satisfaction surveys, Clark Memorial Hospital in Jeffersonville, IN went through a thoughtful process to arrive at an experience that patients said they wanted. Two Lean Six Sigma tools were used--the Voice of the Customer (VoC) and the Affinity Diagram. Even when using these tools, a facility will not be able to accomplish everything the patient may want. Guidelines were set and rules were established for the Process Improvement Team in order to lessen frustration, increase focus, and ultimately be successful. The project's success is driven by the team members carrying its message back to their areas. It's about ensuring that everyone is striving to improve the patients' experience by listening to what they say is being done right and what they say can be done better. And then acting on it.

  13. A pilot rating scale for vortex hazard evaluation

    NASA Technical Reports Server (NTRS)

    Hoh, R. H.

    1975-01-01

    A pilot rating scale is developed for subjective assessment of hazard resulting from wake vortex encounter upsets. The development of the rating scale is based on a survey of 48 pilots regarding the semantic properties of various phrases and a choice of formats for the rating scale. The rating scale can be used to define a hazard/nonhazard boundary as well as to determine a measure of the hazard.

    The single-event upset (SEU) vulnerability of common first- and second-order all-digital-phase-locked loops (ADPLLs) is investigated through field-programmable gate array-based fault injection experiments. SEUs in the highest order pole of the loop filter and fraction-based phase detectors (PDs) may result in the worst case error response, i.e., limit cycle errors, often requiring system restart. SEUs in integer-based linear PDs may result in loss-of-lock errors, while SEUs in bang-bang PDs only result in temporary-frequency errors. ADPLLs with the same frequency tuning range but fewer bits in the control word exhibit better overall SEU performance.

    Large marine crankshaft is the heart of medium-speed diesel engine. The TR forming method used to obtain full-fiber workpiece is considerably complex. However, the metal flow behavior during bending-upsetting process, which determines the forming quality, was seldom studied in previous works. In this study, a finite element model (FEM) was established using constitutive model of 42CrMo4 steel and specified boundary conditions. The simulated results has demonstrated that the early filled metal resists the following metal entering the upper cavity, thereby causing the flash on the upper edge and the unfilled defect on the lower edge of the crank-arm. Further analysis has indicated that larger initial angel of the elbow rod θ0 and a good lubrication condition between dies and workpiece can effectively decrease the volume of flash and eliminate the unfilled defect on the final product.

  17. The Dangers of Failure Masking in Fault-Tolerant Software: Aspects of a Recent In-Flight Upset Event

    2007-01-01

    On 1 August 2005, a Boeing Company 777-200 aircraft, operating on an international passenger flight from Australia to Malaysia, was involved in a significant upset event while flying on autopilot. The Australian Transport Safety Bureau's investigation into the event discovered that an anomaly existed in the component software hierarchy that allowed inputs from a known faulty accelerometer to be processed by the air data inertial reference unit (ADIRU) and used by the primary flight computer, autopilot and other aircraft systems. This anomaly had existed in original ADIRU software, and had not been detected in the testing and certification process for the unit. This paper describes the software aspects of the incident in detail, and suggests possible implications concerning complex, safety-critical, fault-tolerant software.

  18. Discussion series on PURPA related topics: information to customers

    SciTech Connect

    Sturgeon, J I

    1980-08-01

    This volume relates primarily to Time-of-Day rates standard, PURPA IB(d)3, and deals with the content and methods of providing rate and conservation information to customers when Time-of-Day rates are used. Information to customers in the Demonstration and Pilot Projects fell mainly into four categories: administrative communications; explanations of new rate structures; information and advice on load management; and facts, recommendations and encouragements about energy conservation and end-use improvement. Administrative communications were about such matters as the existence of Projects, their funding, their periods of performance, the selection of their test customers, conditions of participation, procedural changes during the tests, and the time and conditions of ending the tests. These communications were important to good customer cooperation. All Demonstration Projects devoted considerable effort to the crucial task of clearly explaining the rationale of Time-of-Use (TOU) pricing and the test rate structures. The Projects then presented the concept of TOU pricing as a means of (a) fairly charging customers the true cost of their electricity and (b) rewarding them for shifting consumption to times when costs are less. For the most part, Demonstration Projects gave specific information on the individual customer's own rate structure and none on any others that were under test. The information was presented in face-to-face interviews, group presentations, television, radio, and print media, and traveling exhibits. The results are evaluated. (LCL)

  19. Solar Particle Induced Upsets in the TDRS-1 Attitude Control System RAM During the October 1989 Solar Particle Events

    The three large solar particle events, beginning on October 19, 1989 and lasting approximately six days, were characterized by high fluences of solar protons and heavy ions at 1 AU. During these events, an abnormally large number of upsets (243) were observed in the random access memory of the attitude control system (ACS) control processing electronics (CPE) on-board the geosynchronous TDRS-1 (Telemetry and Data Relay Satellite). The RAM unit affected was composed of eight Fairchild 93L422 memory chips. The Galileo spacecraft, launched on October 18, 1989 (one day prior to the solar particle events) observed the fluxes of heavy ions experienced by TDRS-1. Two solid-state detector telescopes on-board Galileo, designed to measure heavy ion species and energy, were turned on during time periods within each of the three separate events. The heavy ion data have been modeled and the time history of the events reconstructed to estimate heavy ion fluences. These fluences were converted to effective LET spectra after transport through the estimated shielding distribution around the TDRS-1 ACS system. The number of single event upsets (SEU) expected was calculated by integrating the measured cross section for the Fairchild 93L422 memory chip with average effective LET spectrum. The expected number of heavy ion induced SEU's calculated was 176. GOES-7 proton data, observed during the solar particle events, were used to estimate the number of proton-induced SEU's by integrating the proton fluence spectrum incident on the memory chips, with the two-parameter Bendel cross section for proton SEU'S. The proton fluence spectrum at the device level was gotten by transporting the protons through the estimated shielding distribution. The number of calculated proton-induced SEU's was 72, yielding a total of 248 predicted SEU'S, very dose to the 243 observed SEU'S. These calculations uniquely demonstrate the roles that solar heavy ions and protons played in the production of SEU

  7. Patient or customer?

    PubMed

    Parker, J M

    1999-01-01

    This paper investigates caring in practice within the context of the global imperative of increasing rationalisation of care based on an economic ethic. The notion of the global marketplace has spread to the domain of health services, so that 'health' has come to be seen as a commodity, with the body as its site, and the 'patient' a customer; clinicians work to construct standard pathways through the healthcare supermarket. The challenge for nurses is to work within but also to challenge and resist the reductionist impetus of economically based and commercially driven approaches to health care. They must retain the sense of the value of the wholeness of the person, the deeply personal and profoundly significant professional-recipient relationship, and find ways of demonstrating their capacity to deliver high-quality care in a cost-effective way. Proper and appropriate accountability is a key strategy to maintaining quality nursing as a significant aspect of care. The expansion of the role of the advanced practice nurse is very useful in providing holistic and cost-effective care, though there are currently limitations to scope of practice that need to be removed. The metaphor of the marketplace, underpinned by powerful global economic forces, can draw us into unthinking compliance with its imperatives--but other metaphors are available. Metaphor and creativity are linked, and we need to consider how the creative use of language can facilitate the emergence of new ways of understanding in health care.

    Recently, telecommunication companies have been paying more attention toward the problem of identification of customer churn behavior. In business, it is well known for service providers that attracting new customers is much more expensive than retaining existing ones. Therefore, adopting accurate models that are able to predict customer churn can effectively help in customer retention campaigns and maximizing the profit. In this paper we will utilize an ensemble of Multilayer perceptrons (MLP) whose training is obtained using negative correlation learning (NCL) for predicting customer churn in a telecommunication company. Experiments results confirm that NCL based MLP ensemble can achieve better generalization performance (high churn rate) compared with ensemble of MLP without NCL (flat ensemble) and other common data mining techniques used for churn analysis.

    Kuisma, Markku; Määttä, Teuvo; Hakala, Taisto; Sivula, Tommi; Nousila-Wiik, Maria

    2003-07-01

    The annual patient volume in emergency medical services (EMS) systems is high worldwide. However, there are no comprehensive studies on customer satisfaction for EMS. The authors report how a customer satisfaction survey on EMS patients was conducted, the results, and the possible causes for dissatisfaction. Two prospective customer satisfactions surveys were conducted in an urban EMS system. Consecutive patients treated by EMS received a postal questionnaire approximately two weeks after service. Satisfaction was measured in a scale from 1 (very poor) to 5 (excellent). Neither EMS personnel nor patients were made aware prospectively that patient satisfaction would be measured. Response rates to the surveys were 36.8% (432/1,175) in 2000 and 40.0% (464/1,150) in 2002. The mean general grades for the service were 4.6 and 4.5, respectively. Patients reported the highest degree of dissatisfaction when they were not taken to their hospital of choice, when they perceived that the paramedics were not able to meet their needs, and when paramedics did not introduce themselves or communicate directly with the patient's relatives. In high-volume calls (i.e., frequent chief complaints), the general satisfaction was highest in patients with arrhythmias, breathing difficulties, and hypoglycemia. Patients with drug overdose included the highest proportion of unsatisfied patients. None of the background variables (e.g., gender, transport decision, working shift) was statistically related to general patient satisfaction. This study shows that customer satisfaction surveys can be successfully conducted for EMS. EMS systems should consider routinely using customer satisfaction surveys as a tool for quality measurement and improvement.

  2. Turn customer input into innovation.

    PubMed

    Ulwick, Anthony W

    2002-01-01

    It's difficult to find a company these days that doesn't strive to be customer-driven. Too bad, then, that most companies go about the process of listening to customers all wrong--so wrong, in fact, that they undermine innovation and, ultimately, the bottom line. What usually happens is this: Companies ask their customers what they want. Customers offer solutions in the form of products or services. Companies then deliver these tangibles, and customers just don't buy. The reason is simple--customers aren't expert or informed enough to come up with solutions. That's what your R&D team is for. Rather, customers should be asked only for outcomes--what they want a new product or service to do for them. The form the solutions take should be up to you, and you alone. Using Cordis Corporation as an example, this article describes, in fine detail, a series of effective steps for capturing, analyzing, and utilizing customer input. First come indepth interviews, in which a moderator works with customers to deconstruct a process or activity in order to unearth "desired outcomes." Addressing participants' comments one at a time, the moderator rephrases them to be both unambiguous and measurable. Once the interviews are complete, researchers then compile a comprehensive list of outcomes that participants rank in order of importance and degree to which they are satisfied by existing products. Finally, using a simple mathematical formula called the "opportunity calculation," researchers can learn the relative attractiveness of key opportunity areas. These data can be used to uncover opportunities for product development, to properly segment markets, and to conduct competitive analysis.

  3. The quest for customer focus.

    Gulati, Ranjay; Oldroyd, James B

    2005-04-01

    Companies have poured enormous amounts of money into customer relationship management, but in many cases the investment hasn't really paid off. That's because getting closer to customers isn't about building an information technology system. It's a learning journey-one that unfolds over four stages, requiring people and business units to coordinate in progressively more sophisticated ways. The journey begins with the creation of a companywide repository containing each interaction a customer has with the company, organized not by product, purchase, or location, but by customer. Communal coordination is what's called for at this stage, as each group contributes its information to the data pool separately from the others and then taps into it as needed. In the second stage, one-way serial coordination from centralized IT through analytical units and out to the operating units allows companies to go beyond just assembling data to drawing inferences. In stage three, companies shift their focus from past relationships to future behavior. Through symbiotic coordination, information flows back and forth between central analytic units and various organizational units like marketing, sales, and operations, as together they seek answers to questions like "How can we prevent customers from switching to a competitor?" and "Who would be most likely to buy a new product in the future"? In stage four, firms begin to move past discrete, formal initiatives and, through integral coordination, bring an increasingly sophisticated understanding oftheir customers to bear in all day-to-day operations. Skipping stages denies organizations the sure foundation they need to build a lasting customer-focused mind-set. Those that recognize this will invest their customer relationship dollars much more wisely-and will see their customer-focusing efforts pay offon the bottom line.

    Residents and residency program directors (RPDs) understand that the goal of the residency year is to earn a residency certificate through achievement of established goals and objectives. The customized residency plan provides a map for the resident and RPD to follow throughout the course of the residency year, helping to keep everyone on track to accomplish the established goals and objectives of the program. It also provides information that allows preceptors to take the individual resident's plan into consideration when customizing a learning experience. This article will focus on the process for developing a customized residency plan and implementing it over the course of the residency year.

    Customer preference (CP), or green pricing, may be the financial hedge for electric supply industry integration of photovoltaics. CP is currently defined as a voluntary contribution for energy generated with renewable resources. Several utilities have examined the CP financing of renewables through experimental or implemented programs and market research. This paper first expands the concept of customer preference to include both voluntary and involuntary customer contributions. It then categorizes the features of existing and proposed CP programs. The connections between these features and market research and marketing strategies for new product development from a competitive industry are analyzed.

    Let the whole region be the whole bit rate range that customers are interested in, and a sub-region be a specific bit rate range. The weighting factor of each sub-region is determined according to customers' interest. A new type of region of interest (ROI) is defined for the SNR scalability as the gap between the coding efficiency of SNR scalability scheme and that of the state-of-the-art single layer coding for a sub-region is a monotonically non-increasing function of its weighting factor. This type of ROI is used as a performance index to design a customer oriented SNR scalability scheme. Our scheme can be used to achieve an optimal customer oriented scalable tradeoff (COST). The profit can thus be maximized.

  13. Customer-centered brand management.

    Most executives today agree that their efforts should be focused on growing the lifetime value of their customers. Yet few companies have come to terms with the implications of that idea for their marketing management. Oldsmobile, for example, enjoyed outstanding brand equity with many customers through the 1980s. But as the century wore further on, the people who loved the Olds got downright old. So why did General Motors spend so many years and so much money trying to reposition and refurbish the tired,tarnished brand? Why didn't GM managers instead move younger buyers along a path of less resistance, toward another of the brands in GM's stable--or even launch a wholly new brand geared to their tastes? Catering to new customers, even at the expense of the brand, would surely have been the path to profits. The reason, argue the authors, is that in large consumer-goods companies like General Motors, brands are the raison d'etre. They are the focus of decision making and the basis of accountability. But this overwhelming focus on growing brand equity is inconsistent with the goal of growing customer equity. Drawing on a wide range of current examples, the authors offer seven tactics that will put brands in the service of growing customer equity. These include replacing traditional brand managers with a new position--the customer segment manager; targeting brands to as narrow an audience as possible; developing the capability and the mind-set to hand off customers from one brand to another within the company; and changing the way brand equity is measured by basing calculations on individual, rather than average, customer data.

  19. Managers' perceptions of customers' satisfactions with their hospital cafeteria services.

    PubMed

    Johnston, C M; Upton, E M

    1991-01-01

    It is important that hospital cafeterias deliver products that create customer satisfaction so that financial objectives are met. An exploratory descriptive survey of 12 selected hospital cafeterias used a self-administered questionnaire to determine how satisfied customers were with services provided. It also asked cafeteria managers to give their perceptions of their customers' relative satisfaction/dissatisfaction with the service. Principal components analysis, followed by varimax rotation, identified four underlying constructs of the 15 pre-selected foodservice characteristics used to measure relative satisfaction. A multiple regression model, controlling for country, hospital size and customer demographics, in which the dependent variable was overall rating, found that the independent variables, the underlying rating constructs--food and service--made a much greater impact on overall rating than environment and accessibility. Most cafeteria managers' predictions about their customers' satisfaction were within two standard deviations of their customers' mean scores of satisfaction. While the managers' close association with their service may have accounted for this, it does not necessarily follow that they have the power to implement policy and product improvements.

    Single event upset (SEU) susceptibility of unhardened 6T/SRAM and hardened active delay element (ADE)/SRAM, fabricated with 0.35 μm silicon-on-insulator (SOI) CMOS technology, was investigated at heavy ion accelerator. The mechanisms were revealed by the laser irradiation and resistor-capacitor hardened techniques. Compared with conventional 6T/SRAM, the hardened ADE/SRAM exhibited higher tolerance to heavy ion irradiation, with an increase of about 80% in the LET threshold and a decrease of ∼64% in the limiting upset cross-section. Moreover, different probabilities between 0 → 1 and 1 → 0 transitions were observed, which were attributed to the specific architecture of ADE/SRAM memory cell. Consequently, the radiation-hardened technology can be an attractive alternative to the SEU tolerance of the device-level.

    Analysis of data from the Cosmic Radiation Environment and Dosimetry experiment (CREDO) carried in sun-synchronous polar orbit on UoSat-3 shows the influence of cosmic rays, trapped protons, and solar particles and allows comparison with device behavior. For the quiet-time cosmic ray environment, a comparison has been made between CREDO count rates as a function of LET and the predicted count rate (for several values of rigidity) using the Adams model and applying a full treatment to the isotropic pathlength distribution in the 1 sq cm by 300 micron diodes. Two periods of very intense solar activity have been observed from the data set to date; an analysis of the count rate LET spectra during this event reveals that in the 2-3 GV rigidity range, counts are enhanced up to 103 MeV/(g/sq cm) and that solar flare effects are observed for rigidity values up to 6-7 GV. A CREDO count rate contour map of the South Atlantic Anomaly at 800 km altitude has been constructed from frequent UoSat-3 traversals of this region.

    Ultrafine-grained die-upset Nd-Fe-B magnets are of importance because they provide a wide researching space to redesign the textured structures. Here is presented a route to obtain a new die-upset magnet with substantially improved magnetic properties. After experiencing the optimized heat treatment, both the coercivity and remanent magnetization of the Dy-Cu press injected magnets increased substantially in comparison with those of the annealed reference magnets, which is distinct from the reported experimental results on heavy rare-earth diffusion. To study the mechanism, we analyzed the texture evolution in high-temperature annealed die-upset magnets, which had significant impact on the improvement of remanent magnetization. On basis of the results, we find that the new structures are strongly interlinked with the initial structures. With injecting Dy-Cu eutectic alloy, an optimized initial microstructure was achieved in the near-surface diffused regions, which made preparations for the subsequent texture improvement. Besides, the Dy gradient distribution of near-surface regions of the Dy-Cu press injected magnets was also investigated. By controlling the initial microstructure and subsequent diffusion process, a higher performance magnet is expected to be obtained.

    2012-09-01

    Total Hip Arthroplasty (THA) is a surgical intervention that is being achieving high rates of success, leaving room to research on long run durability, patient comfort and costs reduction. Even so, up to the present, little research has been done to improve the method of manufacturing customized prosthesis. The common customized prostheses are made by full machining. This document presents a different approach methodology which combines the study of medical images, through CAD (Computer Aided Design) software, SLadditive manufacturing, ceramic shell manufacture, precision foundry with Titanium alloys and Computer Aided Manufacturing (CAM). The goal is to achieve the best comfort for the patient, stress distribution and the maximum lifetime of the prosthesis produced by this integrated methodology. The way to achieve this desiderate is to make custom hip prosthesis which are adapted to each patient needs and natural physiognomy. Not only the process is reliable, but also represents a cost reduction comparing to the conventional full machined custom hip prosthesis.

Yet, all too frequently, companies do just that. Either we deny that a problem exists, we exert all our efforts to pin the blame elsewhere, or we "Band-Aid" the problem instead of fixing it, almost guaranteeing that we will face it again and again.

  1. [Customer orientation in ambulant medicine].

    PubMed

    Heinrich, M

    2014-07-01

    Due to developments of the health market, economic aspects of the health system are more relevant. In this upcoming market the patient is regarded as customer and the doctor as provider of medical services. Studies on customer orientation in the ambulant medicine lag behind this dynamic. An aim of the study is to comprehend the attitudes of the doctors referring to the customer orientation. In a second step the findings are discussed according to statements of health-care paticipants. Developments in role comprehension of doctor and patient are focused to gain results in scientific and practical applications. Guideline-supported, partly narrative interviews with n=9 gynaecologists and n=11 general practitioners in Freiburg/Germany are recorded, transcribed and reviewed in a qualitative analysis. The statements of the doctors show patient satisfaction has an incremental meaning sspecially regarding the sequence of patient relationship and economic management of the doctor's workplace. The doctor's role comprehension meets with a refusal of the role of salesman and the patient as customer. The method of interviews is suitable to gather empirical impressions of the doctors. The control sample is adequate, however a bias due to inhomogeneous thematic affinitiy and local social-demographics might be possible. The customer orientation has become an important factor in doctor-patient relationtships. The relevance of the doctor-patient conversation and the risk of misuse of the patient confidence are mentioned by the doctors. The doctor as paternalistic care provider gives way to the customer-focused service provider. The doctor's necessity of autonomyssss and dependency on patient satisfaction have potential for conflict. Intensive mention of customer orientation in medicine in the media emphasises its importance. Rational handling with the possibilities of individual health markets is a prospective challange. Further research could be established in all aspects of

The utility is one of the country`s largest municipally-owned systems. A program was initiated to attract new business without sacrificing the existing businesses. Customer engineers were assigned to the largest customers to learn their needs and provide rate analysis services. Load profile data and technical expertise regarding the customers usage patterns was provided so that the customer could maximize the efficiency of use within given rate structures. Rates were reduced 10 percent for the very largest customers. Time of Use and Interruptible Service Riders were also made available.

  5. The four faces of mass customization.

    PubMed

    Gilmore, J H; Pine, B J

    1997-01-01

    Virtually all executives today recognize the need to provide outstanding service to customers. Focusing on the customer, however, is both an imperative and a potential curse. In their desire to become customer driven, many companies have resorted to inventing new programs and procedures to meet every customer's request. But as customers and their needs grow increasingly diverse, such an approach has become a surefire way to add unnecessary cost and complexity to operations. Companies around the world have embraced mass customization in an attempt to avoid those pitfalls. Readily available information technology and flexible work processes permit them to customize goods or services for individual customers in high volumes at low cost. But many managers have discovered that mass customization itself can produce unnecessary cost and complexity. They are realizing that they did not examine thoroughly enough what kind of customization their customers would value before they plunged ahead. That is understandable. Until now, no framework has existed to help managers determine the type of customization they should pursue. James Gilmore and Joseph Pine provide managers with just such a framework. They have identified four distinct approaches to customization. When designing or redesigning a product, process, or business unit, managers should examine each approach for possible insights into how to serve their customers best. In some cases, a single approach will dominate the design. More often, however, managers will need a mix of some or all of the four approaches to serve their own particular set of customers.

    2003-01-01

    Abstract-Two types of single event effects - bit errors and single event functional interrupts - were observed during heavy-ion testing of the AD8151 crosspoint switch. Bit errors occurred in bursts with the average number of bits in a burst being dependent on both the ion LET and on the data rate. A pulsed laser was used to identify the locations on the chip where the bit errors and single event functional interrupts occurred. Bit errors originated in the switches, drivers, and output buffers. Single event functional interrupts occurred when the laser was focused on the second rank latch containing the data specifying the state of each switch in the 33x17 matrix.

    The technique for evaluating the SEU rate induced by solar particle incidence on spacecraft microelectronics is described, including the contributions from the primary (heavy ion-induced) and secondary proton-induced) SEU mechanisms. The technique is based on original computational models for solar particle energy spectra and for SEU occurrence in electronics. The technique was used to analyze the data of the TDRS-1 Fairchild 93L422 IC exposed to protons and ions during the solar cosmic ray event of September-October 1989. The analysis included the distribution of the microcircuit shielding. A strong dependence of solar proton-to-ion ratio on the shielding thickness was indicated by the calculations.

  8. An Electric Power Purchase Strategy for Bilateral Contracts Focusing on Reliability of Customers

    NASA Astrophysics Data System (ADS)

    Niioka, Satoru; Yokoyama, Ryuichi

    With introducing the competitive electrical power market, large-scale customers can select electric power suppliers. Customers need to consider not only the economical efficiency but also reliability, to decide the amount of electrical power to purchase. This paper develops an economic electric power purchase strategy for customers focusing on reliability. A bilateral contract model expressing electric power suppliers as generators with a forced outage rate is proposed and introduced to assess potential outage risks of the bilateral contract between an electric power supplier and a customer. The outage-related cost, consisting of potential outage risks and the estimated outage cost, is also proposed and introduced as an index of the reliability on the customer side, and an optimal reliability level of a customer is obtained by using the index. Several numerical examples demonstrate the availability of the proposed electric power purchase decision method and reliability improvement strategies for customers are discussed.

    2006-01-01

    SEU from heavy-ions is measured for SOI PowerPC microprocessors. Results for 0.13 micron PowerPC with 1.1V core voltages increases over 1.3V versions. This suggests that improvement in SEU for scaled devices may be reversed. In recent years there has been interest in the possible use of unhardened commercial microprocessors in space because of their superior performance compared to hardened processors. However, unhardened devices are susceptible to upset from radiation space. More information is needed on how they respond to radiation before they can be used in space. Only a limited number of advanced microprocessors have been subjected to radiation tests, which are designed with lower clock frequencies and higher internal core voltage voltages than recent devices [1-6]. However the trend for commercial Silicon-on-insulator (SOI) microprocessors is to reduce feature size and internal core voltage and increase the clock frequency. Commercial microprocessors with the PowerPC architecture are now available that use partially depleted SOI processes with feature size of 90 nm and internal core voltage as low as 1.0 V and clock frequency in the GHz range. Previously, we reported SEU measurements for SOI commercial PowerPCs with feature size of 0.18 and 0.13 m [7, 8]. The results showed an order of magnitude reduction in saturated cross section compared to CMOS bulk counterparts. This paper examines SEUs in advanced commercial SOI microprocessors, focusing on SEU sensitivity of D-Cache and hangs with feature size and internal core voltage. Results are presented for the Motorola SOI processor with feature sizes of 0.13 microns and internal core voltages of 1.3 and 1.1 V. These results are compared with results for the Motorola SOI processors with feature size of 0.18 microns and internal core voltage of 1.6 and 1.3 V.

    The concept of customer engagement and devotion has been applied in various service businesses to keep the customers with business However, a limited number of studies were performed to examine the context of customer engagement and devotion in pharmacy business which focus on the impact of customer perceptions about pharmacists, perceived quality of pharmacy structure, medication price strategy on pharmacy engagement and pharmacy customer devotion in a pharmacy providing pharmaceutical care to the customers. This study aimed to assess a conceptual model depicting the relationships among customer perceptions about pharmacists, pharmacy quality structure, medication price, customer engagement, and customer devotion. And also aimed to assess and measure if there is a direct or indirect relationship between these factors. A quantitative study was conducted by using self-administered questionnaires. Two hundred and fifty three customers who regularly visited the pharmacy were randomly recruited from a purposively selected 30 community pharmacies in Bangkok. The survey was completed during February to April 2016. A structural equation model (SEM) was used to assess the direct and indirect relationships between constructs. A total of 253/300 questionnaires were returned for analysis, and the response rate was 84%. Only perceptions about pharmacist in customers receiving professional pharmacy services was statically significant regarding relationship with pharmacy engagement (beta=0.45). Concurrently, the model from empirical data fit with the hypothetical model (p-value = 0.06, adjusted chi-square (CMIN/DF)=1.16, Goodness of Fit Index (GFI)=0.93, Comparatively Fit Index (CFI)=0.99, and Root Mean Square Error Approximation (RMSEA)=0.03). The study confirmed the indirect positive influence of customer perceptions about pharmacist on pharmacy customer devotion in providing pharmacy services via pharmacy engagement It was customer perceptions about pharmacist that influenced

    Southern California Edison has instituted a new business plan in 1991 for its Customer Solutions Department. One of the goals is to increase customer satisfaction through the measurement and continuous enhancement of value in each major customer segment. One of many tactics employed to implement this strategy was the establishment of a customer satisfaction measurement program and a customer satisfaction implementation program. The measurement of customer satisfaction baselines and development of feedback systems focuses on business lines with a high volume of customer transactions: customer communication centers, local/front offices, field services/meter readers, energy efficiency services and the electric distribution system design function. The customer satisfaction surveys are administered to approximately 10,000 customers annually. Using the results of the customer satisfaction baseline measurements, more than 200 employees formed teams to identify and implement more than 225 action items aimed at improving customer satisfaction. These strategies remain in place for 1994 and beyond.

    This paper addresses the accuracy of radiation-induced upset-rate predictions in space using the results of ground-based measurements together with standard environmental and device models. The study is focused on two part types - 16 Mb NEC DRAM's (UPD4216) and 1 Kb SRAM's (AMD93L422) - both of which are currently in space on board the Microelectronics and Photonics Test Bed (MPTB). To date, ground-based measurements of proton-induced single event upset (SEM cross sections as a function of energy have been obtained and combined with models of the proton environment to predict proton-induced error rates in space. The role played by uncertainties in the environmental models will be determined by comparing the modeled radiation environment with the actual environment measured aboard MPTB. Heavy-ion induced upsets have also been obtained from MPTB and will be compared with the "predicted" error rate following ground testing that will be done in the near future. These results should help identify sources of uncertainty in predictions of SEU rates in space.

    Murakoshi, Akiko; Kunimatsu, Taketoshi; Saito, Ayano

    This paper aims to reveal the fundamental features of customer satisfaction with train schedules, which is one of the most basic services provided by a railway company. A customer satisfaction survey of passengers who frequently utilize three lines in the metropolitan area was conducted; we obtained the following findings: (a) out of nine factors to evaluate a train schedule from a passenger's viewpoint, the four most important ones are the frequency of trains running, punctuality, congestion rate, and time distance; (b) the ride-frequency influences the degree of satisfaction with train schedules in a particular line; and (c) it is important to set a numeric goal for the level of customer satisfaction by grasping the relationship between the transport service and a passenger's satisfaction with that service. The difference between customer satisfaction and passenger disutility is also discussed. The findings are expected to help conduct customer satisfaction surveys and also to form the basis for establishing a method by which to evaluate a train schedule from passengers' satisfaction ratings.

  4. Customization of medical report data.

    Reiner, Bruce I

    2010-08-01

    Structured reporting offers a number of theoretical advantages, perhaps the most important of which is creation of standardized report databases. The standardized data created can in turn be used to customize data display, report content, historical data retrieval, interpretation analysis, and results communication in both a context and user-specific manner. In addition, these referenceable report databases can be used to facilitate the practice of evidence based medicine, through data-driven meta-analysis and determination of best practice guidelines. This concept will only be realized if the customized data delivery technology provides real and tangible value to end users, accentuates workflow, can be seamlessly integrated into existing information system technologies, and be shown to yield reproducibility of the evidence domain. The time is here for the medical imaging and clinical communities to embrace this vision in order to improve clinical outcomes and patient safety.

  5. New Thoughts of Customer Value Study

    Sun, Hong; Su, Zhuqing

    Customer value theory's discovery has established to take customer and even customer value as the center position for research of marketing, which is good progress of marketing theory. However, in the past researches for customer value emphasized customer perceived value, there was no good answer on which customers perceived with what scale. This paper states that customer perceived value is established in value transmission mechanism of its rear, which is based on the role of consumption values. With a market environment's change, and the strength of consumer's sovereignty consciousness, especially when personal consumption is identified and developed to become a mainstream consume culture in nowadays society, the role of the transmission is increasingly in evidence. Studies of consumeption values are to deepen customer value theory.

    Tomczyk, Dennis J

    2002-06-01

    The ability of managed care providers to deliver high-quality customer service to managed care customers depends on their adoption of basic customer-service principles. To apply these principles effectively, providers need to understand and work to exceed the particular needs and expectations of these customers, which include boards of directors, senior executives, physicians, healthcare providers, clinical and patient financial services managers and staff, employers, brokers, and patients. Although these needs and expectations can be predicted to some extent, providers would be wise to implement regular surveys of customers and an open procedure for soliciting customer feedback about service issues. Better customer service for the broad range of managed care customers translates into higher levels of employer and patient satisfaction, which ultimately benefits providers.

    Contact lenses are increasingly used in laboratories for in vivo animal retinal imaging and pre-clinical studies. The lens shapes often need modification to optimally fit corneas of individual test subjects. However, the choices from commercially available contact lenses are rather limited. Here, we report a flexible method to fabricate customized hydrogel contact lenses. We showed that the fabricated hydrogel is highly transparent, with refractive indices ranging from 1.42 to 1.45 in the spectra range from 400 nm to 800 nm. The Young’s modulus (1.47 MPa) and hydrophobicity (with a sessile drop contact angle of 40.5°) have also been characterized experimentally. Retinal imaging using optical coherence tomography in rats wearing our customized contact lenses has the quality comparable to the control case without the contact lens. Our method could significantly reduce the cost and the lead time for fabricating soft contact lenses with customized shapes, and benefit the laboratorial-used contact lenses in pre-clinical studies.

  10. Identification with the retail organization and customer-perceived employee similarity: effects on customer spending.

    2012-09-01

    Two constructs important to academicians and managers are the degree to which employees and customers identify with an organization, employee organizational identification (employee OI) and customer-company identification (customer identification), respectively. This research examines the effects of these identification constructs and the related construct of customer perceived similarity to employees on customer spending. Via a 1-year multilevel study of 12,047 customers and 1,464 store employees (sales associates) covering 212 stores of a specialty apparel retailer, our study contributes to the literature in 2 critical ways. First, we expand the theoretical network of employee OI and customer identification by examining the related construct of a customer's perceived similarity to store employees. We examine the incremental (not fully mediated) main and interaction effects of customer-perceived similarity to employees and employee OI on customer spending. Second, we examine the effect of customer identification on customer spending relative to the effect of customer satisfaction on customer spending. Thus, our study also contributes by demonstrating a potential complementary route to achieve customer spending (customer identification), a route that may be more readily affected by management than the efforts required for a sustained increase in customer satisfaction. Implications for academics and managers are offered.

    Combining broad-beam circuit level single-event upset (SEU) response with heavy ion microprobe charge collection measurements on single silicon-germanium heterojunction bipolar transistors improves understanding of the charge collection mechanisms responsible for SEU response of digital SiGe HBT technology. This new understanding of the SEU mechanisms shows that the right rectangular parallele-piped model for the sensitive volume is not applicable to this technology. A new first-order physical model is proposed and calibrated with moderate success.

  20. Dynamic pricing for residential electric customers: a ratepayer advocate's perspective

    SciTech Connect

    Brand, Stefanie A.

    2010-07-15

    New Jersey's Rate Counsel urges that the consideration of alternative pricing mechanisms aimed at encouraging a reduction or shift in residential electricity usage include recognition of the needs and wishes of consumers. Without consumer buy-in, any such pricing mechanisms will fail. To achieve the desired goals, customers must be able to understand and react to the pricing signals. (author)

  1. Research of Customized Aortic Stent Graft Manufacture

    NASA Astrophysics Data System (ADS)

    Zhang, Lei; Chen, Xin; Liu, Muhan

    2017-03-01

    Thoracic descending aorta diseases include aortic dissection and aortic aneurysm, of which the natural mortality rate is extremely high. At present, endovascular aneurysm repair (EVAR) has been widely used as an effective means for the treatment of descending aortic disease. Most of the existing coating stents are standard design, which are unable to meet the size or structure of different patients. As a result, failure of treatment would be caused by dimensional discrepancy between stent and vessels, which could lead to internal leakage or rupture of blood vessels. Therefore, based on rapid prototyping sacrificial core - coating forming (RPSC-CF), a customized aortic stent graft manufactured technique has been proposed in this study. The aortic stent graft consists of film and metallic stent, so polyether polyurethane (PU) and nickel-titanium (NiTi) shape memory alloy with good biocompatibility were chosen. To minimum film thickness without degrading performance, effect of different dip coating conditions on the thickness of film were studied. To make the NiTi alloy exhibit super-elasticity at body temperature (37°C), influence of different heat treatment conditions on austenite transformation temperature (Af) and mechanical properties were studied. The results show that the customized stent grafts could meet the demand of personalized therapy, and have good performance in blasting pressure and radial support force, laying the foundation for further animal experiment and clinical experiment.

  2. Least cost planning from a customer`s perspective

    Sutherland, R.J.

    1992-03-02

    In this paper, I offer some thoughts about least cost planning, not from the perspective of the regulator or utility, but from the perspective of a residential customer. The problem that I address is, as a homeowner in northern Virginia, I am about to make a long term fuel choice for my household, where the options include, natural gas, electricity and fuel oil. An additional choice is the energy efficiency capital investment in my home that could decrease my monthly fuel costs. My decision process, hopefully as a rational consumer, offers implications about the efficiency of various services provided by all three fuel suppliers, including the local natural gas distribution companies (LDC).

    2009-01-01

    The authors examined 2 forms of customization in a Web-based recruitment context. Hypotheses were tested in a controlled study in which participants viewed multiple Web-based job postings that each included information about multiple fit categories. Results indicated that customization of information regarding person-organization (PO), needs-supplies, and demands-abilities (DA) fit (fit information customization) and customization of the order in which these fit categories were presented (configural customization) had differential effects on outcomes. Specifically, (a) applicant pool PO and DA fit were greater when fit information customization was provided, (b) applicant pool fit in high- versus low-relevance fit categories was better differentiated when configural customization was provided, and (c) overall application rates were lower when either or both forms of customization were provided.

  19. Business marketing: understand what customers value.

    PubMed

    Anderson, J C; Narus, J A

    1998-01-01

    How do you define the value of your market offering? Can you measure it? Few suppliers in business markets are able to answer those questions, and yet the ability to pinpoint the value of a product or service for one's customers has never been more important. By creating and using what the authors call customer value models, suppliers are able to figure out exactly what their offerings are worth to customers. Field value assessments--the most commonly used method for building customer value models--call for suppliers to gather data about their customers firsthand whenever possible. Through these assessments, a supplier can build a value model for an individual customer or for a market segment, drawing on data gathered form several customers in that segment. Suppliers can use customer value models to create competitive advantage in several ways. First, they can capitalize on the inevitable variation in customers' requirements by providing flexible market offerings. Second, they can use value models to demonstrate how a new product or service they are offering will provide greater value. Third, they can use their knowledge of how their market offerings specifically deliver value to craft persuasive value propositions. And fourth, they can use value models to provide evidence to customers of their accomplishments. Doing business based on value delivered gives companies the means to get an equitable return for their efforts. Once suppliers truly understand value, they will be able to realize the benefits of measuring and monitoring it for their customers.

  2. {open_quotes}Understanding district energy customer behavior - the key to getting customers and keeping them happy{close_quotes}

    SciTech Connect

    Kattner, J.F.

    1995-09-01

    The market share achieved by district energy systems is frequently represented as a percentage of a particular country`s total energy consumption, or as a percentage of the energy used for heating and cooling. While such characterizations of district energy`s market share are valid and important from a producer`s perspective, the position of the customer is not well represented. The effectiveness of communicating market share in this way greatly depends on the district energy customers` knowledge about the local, regional and national energy markets. It also fails to take into account the differences among customer buildings and their individual energy consumption patterns. An alternative view of market share is suggested when the perspective of the district energy markets shifts from that of the producer`s to the ends user`s. End users of district energy typically are responsible for the ownership and/or the operation of a building. This includes providing energy for comfort, lighting and any processes being conducted in the building. Fundamentally, district energy customers are in the property management business. Their business operations are represented and rated with respect to the building area they manage. Frequently, several buildings are managed by one company. An extensive amount of research has been done about the behavior of consumers when making buying decisions. This includes the fact that product and service buying behavior differs. Also, the field of customer satisfaction is rich with clues on how to keep our customers happy with their decisions to use district energy. This report presents key considerations about buyer behavior and customer satisfaction as they relate to marketing in the district energy field.

    Spectral output of fluorescent lamps can be precisely adjusted by using computer-assisted analysis for custom blending lamp phosphors. With technique, spectrum of main bank of lamps is measured and stored in computer memory along with emission characteristics of commonly available phosphors. Computer then calculates ratio of green and blue intensities for each phosphor according to manufacturer's specifications and plots them as coordinates on graph. Same ratios are calculated for measured spectrum. Once proper mix is determined, it is applied as coating to fluorescent tubing.

    Living cells have evolved a broad array of complex signaling responses, which allows them to survive diverse environmental challenges and to execute specific physiological functions. Our increasingly sophisticated understanding of the molecular mechanisms of cell signaling networks in eukaryotes has revealed a remarkably modular organization, and synthetic biologists are exploring how this can be exploited to engineer cells with novel signaling behaviors. This approach is beginning to reveal the logic of how cells might evolve innovative new functions, and moves us towards the exciting possibility of engineering custom cells with precise sensing–response functions that could be useful in medicine and biotechnology.

  6. Customized ATP towpreg. [Automated Tow Placement

    NASA Technical Reports Server (NTRS)

    Sandusky, Donald A.; Marchello, Joseph M.; Baucom, Robert M.; Johnston, Norman J.

    1992-01-01

    Automated tow placement (ATP) utilizes robotic technology to lay down adjacent polymer-matrix-impregnated carbon fiber tows on a tool surface. Consolidation and cure during ATP requires that void elimination and polymer matrix adhesion be accomplished in the short period of heating and pressure rolling that follows towpreg ribbon placement from the robot head to the tool. This study examined the key towpreg ribbon properties and dimensions which play a significant role in ATP. Analysis of the heat transfer process window indicates that adequate heating can be achieved at lay down rates as high as 1 m/sec. While heat transfer did not appear to be the limiting factor, resin flow and fiber movement into tow lap gaps could be. Accordingly, consideration was given to towpreg ribbon having uniform yet non-rectangular cross sections. Dimensional integrity of the towpreg ribbon combined with customized ribbon architecture offer great promise for processing advances in ATP of high performance composites.

    The present investigation was carried out to evaluate the densification, mechanical properties, microstructural and fractrography effects of AISI 8630 steel composition developed through powder preform forging under different heat treated conditions. Sintered preforms of different aspect ratios such as 0.6, 0.9, and 1.2 were hot upset forged to disc shape to different height strain to analysis the densification mechanism. Certain relationships relating strains, Poisson's ratio relating densification have revealed the effect of preform geometry on densification kinetics and resulted in the polynomial expression with justified regression coefficient greater the 0.9 or unity. The preforms of aspect ratio of 1.1 were hot upset forged to square cross section bars and transferred to different quenching medium like oil, water, furnace and air to assess its mechanical properties. Comparing the temperament of the heat treatments, sintered forged homogenised water quenched sample upshot in the maximum Tensile strength with least per centage elongation andthe furnace cooled sample shows the maximum toughness with desirable per centage elongation and least tensile strength. Microstructure stated the presence of varying ferrite and pearlite distribution and fractograph studies has disclosed the mixed mode of failure on the effect of varying heat treatments progression has affected the properties significantly.

  8. [Possibility of interactions between prescription drugs and OTC drugs (2nd report)--interaction between levodopa preparation and OTC Kampo medicines for upset stomach].

    2006-11-01

    Our series of studies aimed to examine the possibility of interactions between prescription drugs and over-the-counter (OTC) drugs by monitoring plasma drug concentrations in rats. When a levodopa preparation indicated for patients with Parkinson's disease was administered in combination with Takeda Kampo Ichoyaku K-matsu (A), Taisho Kampo Ichoyaku (B), or Kanebo Kampo Ichoyaku H(C), which are OTC kampo medicines for upset stomach, the plasma levodopa concentration-time curves were shifted downward and the AUC for levodopa was significantly lowered. These results indicate that there may be some interactions between the levodopa preparation and these OTC kampo medicines when ingested together, which leads to a reduction in the bioavailability of levodopa. On the other hand, concomitant administration of the levodopa preparation with Takeda Kampo Ichoyaku A-matsu (D) did not alter any of the pharmacokinetic parameters for levodopa. According to the package inserts for the OTC kampo medicines, A, B and C, but not D, contain metallic additives, such as aluminum silicate and magnesium stearate. In addition, combination with a kampo basis of D (Koshaheiisan-ka-shakuyaku) showed no detectable change in levodopa bioavailability. From these results, it was concluded that metallic additives may play an essential role in generating the drug-interaction between levodopa preparation and OTC kampo medicine for upset stomach.

    The plastic behavior during deformation by upsetting and its effect on the microstructure in the polycrystalline Ni2.19Fe0.04Mn0.77Ga alloy are studied. The temperatures of martensitic and magnetic phase transformations were determined by the method for analyzing the temperature dependence of the specific magnetization as M F = 320 K, A S = 360 K, and T C = 380 K. Using differential scanning calorimetry, it is shown that the phase transition from the ordered phase L21 to the disordered phase B2 is observed in the alloy during sample heating in the temperature range of 930-1070 K. The melting temperature is 1426 K. An analysis of the load curves constructed for sample deposition at temperatures of 773, 873, and 973 K shows that the behavior of the stress-strain curve at a temperature of 773 K is inherent to cold deformation. The behavior of the dependences for 873 and 973 K is typical of hot deformation. After deforming the alloy, its microstructure is studied using backscattered scanning electron microscopy. Plastic deformation of the alloy at study temperatures results in grain structure fragmentation in the localized deformation region. At all temperatures, a recrystallized grain structure is observed. It is found that the structure is heterogeneously recrystallized after upsetting at 973 K due to the process intensity at such a high temperature. The alloy microstructure after plastic deformation at a temperature of 873 K is most homogeneous in terms of the average grain size.

  11. A Correlational Study of How Airline Customer Service and Consumer Perception of Airline Customer Service Affect the Air Rage Phenomenon

    NASA Technical Reports Server (NTRS)

    Hunter, Joyce A.

    2007-01-01

    Between 1995 and 2000, customer service declined throughout the airline industry, as reported in February 2001 by the U.S. Department of Transportation (2001). One of the biggest problems today within the airline industry is the constant complaining from customers regarding the deterioraton of service (McCollough, Berry, & Yadav, 2000). Since 1995, unfortunately no airline has been immune from service deterioration, as reported by the Airline Quality Rating, an annual report by two airline industry experts who analyzed Department of Transportation statistics (Harrison & Kleinsasser, 1999). The airline' refusal to recognize the issue of customer service has perpetuated an environment that has become dangerous and detrimental to the traveling public as well as to airline employees, which in turn has fueled a new phenomenon, now referred to as "air rage".

  12. Getting even for customer mistreatment: the role of moral identity in the relationship between customer interpersonal injustice and employee sabotage.

    PubMed

    Skarlicki, Daniel P; van Jaarsveld, Danielle D; Walker, David D

    2008-11-01

    Research on the "dark side" of organizational behavior has determined that employee sabotage is most often a reaction by disgruntled employees to perceived mistreatment. To date, however, most studies on employee retaliation have focused on intra-organizational sources of (in)justice. Results from this field study of customer service representatives (N = 358) showed that interpersonal injustice from customers relates positively to customer-directed sabotage over and above intra-organizational sources of fairness. Moreover, the association between unjust treatment and sabotage was moderated by 2 dimensions of moral identity (symbolization and internalization) in the form of a 3-way interaction. The relationship between injustice and sabotage was more pronounced for employees high (vs. low) in symbolization, but this moderation effect was weaker among employees who were high (vs. low) in internalization. Last, employee sabotage was negatively related to job performance ratings.

  13. Uranium enrichment deferral charges and the customer payment period

    SciTech Connect

    1983-10-21

    A Department of Energy (DOE) Office of the Inspector General report entitled Dollar Impact of Financial Management Decisions in the Uranium Enrichment Program includes two recommendations which, if implemented, would change the interest rate DOE uses to compute its charges to customers deferring delivery of uranium enrichment services and reduce the 30-day interest-free period customers are allowed for making payment on DOE-provided enrichment serivces. GAO believes that an interest rate based on the current market yield on Treasury borrowings with maturities comparable to the period of deferrals (current-market-yield rate) better reflects the cost of Treasury borrowings and is therefore more appropriate than either the rate DOE currently uses or the rate recommended by DOE's Inspector General. DOE agrees and plans to use the current-market-yield rate in any deferral under future contracts. GAO also believes reducing the customer payment period has merit from a cash management standpoint. However, the effect of such an action on DOE's competitive position among foreign suppliers of enrichment services needs to be considered before any such reduction is made.

    Advanced measurement methods using microelectronic test chips are described. These chips are intended to be used in acquiring the data needed to qualify Application Specific Integrated Circuits (ASIC's) for space use. Efforts were focused on developing the technology for obtaining custom IC's from CMOS/bulk silicon foundries. A series of test chips were developed: a parametric test strip, a fault chip, a set of reliability chips, and the CRRES (Combined Release and Radiation Effects Satellite) chip, a test circuit for monitoring space radiation effects. The technical accomplishments of the effort include: (1) development of a fault chip that contains a set of test structures used to evaluate the density of various process-induced defects; (2) development of new test structures and testing techniques for measuring gate-oxide capacitance, gate-overlap capacitance, and propagation delay; (3) development of a set of reliability chips that are used to evaluate failure mechanisms in CMOS/bulk: interconnect and contact electromigration and time-dependent dielectric breakdown; (4) development of MOSFET parameter extraction procedures for evaluating subthreshold characteristics; (5) evaluation of test chips and test strips on the second CRRES wafer run; (6) two dedicated fabrication runs for the CRRES chip flight parts; and (7) publication of two papers: one on the split-cross bridge resistor and another on asymmetrical SRAM (static random access memory) cells for single-event upset analysis.

    The bank Banco Credito e Inversiones (BCI) started its virtual bank in 1996 and its registered customers perform currently more than 10,000 Internet transactions daily, which typically cause les than 10% of traditional transaction costs. Since most of the customers are still not registered for online banking, one of the goals of the virtual bank is to increase then umber of registered customers. Objective of the presented work was to identify customers who are likely to perform online banking but still do not use this medium for their transactions. This objective has been reached by determining profiles of registered customers who perform many transactions online. Based on these profiles the bank's Data Warehouse is explored for twins of these heavy users that are still not registered for online banking. We applied clustering in order to group the registered customers into five classes. One of these classes contained almost 30% of all registered customers and could clearly be identified as class of heavy users. Next a neural network assigned online customers to the previously found five classes. Applying the network trained on online customers to all the bank customers identified twins of heavy users that, however had not performed online transactions so far. A mailing to these candidates informing about the advantages of online banking doubled the number of registrations compared to previous campaigns.

    No matter how hard companies try, their approaches to innovation often don't grow the top line in the sustained, profitable way investors expect. For many companies, there's a huge difference between what's in their business plans and the market's expectations for growth (as reflected in firms' share prices, market capitalizations, and P/E ratios). This growth gap springs from the fact that companies are pouring money into their insular R&D labs instead of working to understand what the customer wants and using that understanding to drive innovation. As a result, even companies that spend the most on R&D remain starved for both customer innovation and market-capitalization growth. In this article, the authors spell out a systematic approach to innovation that continuously fuels sustained, profitable growth. They call this approach customer-centric innovation, or CCI. At the heart of CCI is a rigorous customer R&D process that helps companies to continually improve their understanding of who their customers are and what they need. By so doing, they consistently create or improve their customer value proposition. Customer R&D also focuses on better ways of communicating value propositions and delivering the complete experience to real customers. Since so much of the learning about customers and so much of the experimentation with different segmentations, value propositions, and delivery mechanisms involve the people who regularly deal with customers, it is absolutely essential for frontline employees to be at the center of the CCI process. Simply put, customer R&D propels the innovation effort away from headquarters and the traditional R&D lab out to those closest to the customer. Using the example of the luggage manufacturer Tumi, the authors provide a step-by-step approach for achieving true customer-centric innovation.

    Pursuing a customer-focused strategy in manufacturing organizations requires employees across functions to embrace the importance of understanding customer needs and to align their everyday efforts with the goal of satisfying and retaining customers. Little prior research has examined what factors influence employee customer orientation in manufacturing settings. Drawing on the attraction-selection-attrition model, upper-echelons theory, and contingency theories of leadership, this study investigated the joint influences of functional roles' proximity to external customers and the senior leadership team's customer orientation on employee customer orientation. Hierarchical linear modeling results based on data obtained from 4,299 employees and 403 senior leaders from 42 facilities of a global manufacturer operating in 16 countries revealed that employees occupying customer-contact roles had the highest level of customer orientation, followed by employees occupying production roles, and then by those in support roles. In addition, there was a positive relationship between the senior leadership team's customer orientation and employee customer orientation for all 3 functional roles. The positive relationship between the senior leadership team and employee customer orientation was the strongest for employees in support roles, suggesting that lower levels of proximity to external customers may create a greater need for leadership in developing employees' customer-oriented attitudes.

    A national study designed to assess the reliability and validity of a nursing home customer satisfaction survey is summarized. One hundred fifty-nine facilities participated, each responsible for the distribution and collection of 200 questionnaires randomly sent to the home of the resident's responsible party. A total of 9053 completed questionnaires were returned, for an average adjusted response rate of 53%. The factor analysis identified 4 scales: Comfort and Cleanliness, Nursing, Food Services, and Facility Care and Services, each with high reliability. Based on a multiple regression analysis, the scales were shown to have good criterion-related validity, accounting for 64% of the variance in overall quality ratings. Comparisons based on select characteristics indicated significantly different satisfaction ratings among facilities. The results are interpreted as providing evidence for the construct validity of a multidimensional customer satisfaction scale with measured reliability and criterion-related validity. Moreover, the scale can be used to differentiate satisfaction levels among facilities.

    An increasingly common challenge in antenatal care of the small for gestational age (SGA) fetus is the distinction between the constitutionally (physiologically) small fetus and the fetus affected by pathological intrauterine growth restriction (IUGR). We discuss here the rationale and the evidence for the use of customized growth percentiles for the purpose of distinguishing between the fetus with true IUGR and the fetus with constitutional SGA. We also provide estimates of the potential effects of adopting ethnicity-specific birth weight curves on the rates of SGA and large for gestational age status in multi-ethnic metropolitan cities in North America and Europe, such as the City of Toronto. Using customized growth percentiles would result in a considerable decline in the rate of a false-positive diagnosis of SGA among visible minorities, and improve the detection rate of true large for gestational age fetuses among these groups.
