A single-machine scheduling problem with maintenance activities to minimize makespan  

Microsoft Academic Search

We study a single-machine scheduling problem with periodic maintenance activity under two maintenance stratagems. Although the scheduling problem with single or periodic maintenance and nonresumable jobs has been well studied, most of past studies considered only one maintenance stratagem. This research deals with a single-machine scheduling problem where the machine should be stopped for maintenance after a fixed periodic interval

Resolutions of Problems that Occurred in SPEAR3 Magnet Production  

SciTech Connect

Some problems occurred during the SPEAR3 magnet production at IHEP, China. It was very hard to find resolution from existing knowledge of those problems. It was possible that similar problems might have happen in building accelerator magnet in other institutes before, but they were not addressed in public papers. These problems were discussed and solved by engineers from both SLAC and IHEP after conducting certain experiments. Traditionally, the magnet design and measurement data have been always well documented and addressed in papers, but the production experiences have not been recorded adequately. It is the goal of this paper to record the problems and their resolutions during SPEAR3 magnet production at IHEP China, which will certainly benefit future magnet projects.

A resolution of the ascertainment sampling problem. III. Pedigrees.  

PubMed Central

When nuclear families are sampled by an ascertainment procedure whose properties are not known, biased estimates of genetic parameters will arise if an incorrect specification of the ascertainment procedure is made. Elsewhere we have put forward a resolution of this problem by introducing an ascertainment-assumption-free (AAF) method, for nuclear family data, which gives asymptotically unbiased estimators no matter what the true nature of the ascertainment process. In the present paper we extend this method to cover pedigree data. Problems that arise with pedigrees but not with families--for example, the question of which families in a pedigree are "ascertainable"--are also considered. Comparisons of numerical results for pedigrees and nuclear families are also made.

High-resolution structure prediction and the crystallographic phase problem.  

PubMed

The energy-based refinement of low-resolution protein structure models to atomic-level accuracy is a major challenge for computational structural biology. Here we describe a new approach to refining protein structure models that focuses sampling in regions most likely to contain errors while allowing the whole structure to relax in a physically realistic all-atom force field. In applications to models produced using nuclear magnetic resonance data and to comparative models based on distant structural homologues, the method can significantly improve the accuracy of the structures in terms of both the backbone conformations and the placement of core side chains. Furthermore, the resulting models satisfy a particularly stringent test: they provide significantly better solutions to the X-ray crystallographic phase problem in molecular replacement trials. Finally, we show that all-atom refinement can produce de novo protein structure predictions that reach the high accuracy required for molecular replacement without any experimental phase information and in the absence of templates suitable for molecular replacement from the Protein Data Bank. These results suggest that the combination of high-resolution structure prediction with state-of-the-art phasing tools may be unexpectedly powerful in phasing crystallographic data for which molecular replacement is hindered by the absence of sufficiently accurate previous models.

Solvent refined coal demonstration projects; NEPA problems and resolutions  

SciTech Connect

After approximately three years of preparatory work, the Final Environmental Statements for the two proposed Solvent Refined Coal demonstration projects (SRC-I and SRC-II) have been completed by the Oak Ridge National Laboratory and issued by the Department of Energy. These EISs were prepared in a climate of political, technological, and environmental uncertainties. New regulations on EIS preparation, the emerging SRC technology, and the absence of any prior EISs on direct coal liquefaction projects made these EISs pioneering, precedent-setting documents. The problems that arose during the EIS preparation tended to fall into three categories: policy, technical, and institutional. This report probes behind the scenes of these 1300-page documents to share the experience gained in uncovering and solving the major problems. The bottom line of the whole experience is that despite these problems, NEPA works. The concluding section of the report summarizes recommendations for those facing EISs on synfuel or similarly controversial technologies. Many of the lessons learned are transferable to othe sponsors and other projects.

A fine tuning free resolution of the cosmological constant problem  

SciTech Connect

In a recent paper we discovered that a fermionic condensate is formed from gravitational interactions due to the covariant coupling of fermions in the presence of a torsion-fermion contact interaction.The condensate gap gives a negative contribution to the bare cosmological constant. In this letter, we show that the cosmological constant problem can be solved without fine tuning of the bare cosmological constant. We demonstrate how a universe with a large initial cosmological constant undergoes inflation, during which time the energy gap grows as the volume of the universe. Eventually the gap becomes large enough to cancel out the bare cosmological term, inflation ends and we end up in a universe with an almost vanishing cosmological term. We provide a detailed numerical analysis of the system of equations governing the self regulating relaxation of the cosmological constant.

Towards the resolution of the solar neutrino problem  

NASA Astrophysics Data System (ADS)

A number of experiments have accumulated over the years a large amount of solar neutrino data. The data indicate that the observed solar neutrino flux is significantly smaller than expected and, furthermore, that the electron neutrino survival probability is energy dependent. This 'solar neutrino problem' is best solved by assuming that the electron neutrino oscillates into another neutrino species. Even though one can classify the solar neutrino deficit as strong evidence for neutrino oscillations, it is not yet considered a definitive proof. Traditional objections are that the evidence for solar neutrino oscillations relies on a combination of hard, different experiments, and that the Standard Solar Model (SSM) might not be accurate enough to precisely predict the fluxes of different solar neutrino components. Even though it seems unlikely that modifications to the SSM alone can explain the current solar neutrino data, one still cannot completely discount the possibility that a combination of unknown systematic errors in some of the experiments and certain modifications to the SSM could conspire to yield the observed data. To conclusively demonstrate that there is indeed new physics in solar neutrinos, new experiments are aiming at detecting 'smoking gun' signatures of neutrino oscillations, such as an anomalous seasonal variation in the observed neutrino flux or a day-night variation due to the regeneration of electron neutrinos in the Earth. In this dissertation we study the sensitivity reach of two upcoming neutrino experiments, Borexino and KamLAND, to both of these effects. Results of neutrino oscillation experiments for the case of two-flavor oscillations have always been presented on the (sin(sup 2) 2(theta), (Delta)m(sup 2)) parameter space. We point out, however, that this parameterization misses the half of the parameter space (pi)/4 < (theta) (le) (pi)/2, which is physically inequivalent to the region 0 (le) (theta) (le) (pi)/4 in the presence of matter effects. The MSW solutions to the solar neutrino problem can extend to the ((theta) greater than (pi)/4) side. Furthermore, even the 'vacuum oscillation' solutions are affected by solar matter effects and hence are different in the two sides.

The USDA UV radiation network currently consists of four high resolution spectroradiometers located at Table Mountain, Colorado (deployed 11/1998); the Atmospheric Radiation Measurement testbed site at Southern Great Plains, Oklahoma (deployed 10/1999); Beltsville, Maryland (deployed 11/1999); and Fort Collins, Colorado (deployed 10/2002). These spectroradiometers contain Jobin Yvon"s one meter asymmetric Czerny-Turner double additive spectrometer. The instruments measure total horizontal radiation in the 290nm to 360nm range, once every 30 minutes, with a nominal full-width at half-maximum (FWHM) of 0.1nm. We describe data quality control techniques as well as the data processing required to convert the raw data into calibrated irradiances. The radiometric calibration strategies using NIST FEL lamps, portable field calibrators, and vicarious calibrations using UVMFRSR data are discussed and a statistical summary of network performance is presented.

Resolution Analysis for Experiment Planning of a Nonlinear Seafloor Acoustic Inverse Problem  

NASA Astrophysics Data System (ADS)

Geoacoustic inversion is the estimation of physical properties of the ocean bottom as a continuous function of position (or depth) in the seafloor given acoustic receptions in the water column. It is closely related to marine reflection seismology but also has features of refraction seismology, and uses sonar equipment and less than ideal geometries because accurate scientific determination of the seafloor may not be the primary goal of the experiments. However, the authors show how a pre-measurement inverse theory resolution analysis can be used as part of experiment planning regarding sensor placement and ship tracks, such that a desire for an experimental configuration giving the most information in bottom inversion can be quantitatively balanced with that for other needs like tracking and communication. This nonlinear geoacoustic inverse problem is ill-posed, so that one can only estimate the continuous function of seafloor properties to a limited resolution. This limited resolution varies with experiment geometry, frequency, and other such factors, and can be quantified in either a frequentist or Bayesian framework. Given statistics of the measurement noise (but without any new measurements themselves), the resolution can be quantified exactly for a linear inverse problem, and compared between different experiment geometries. Nonlinear problems complicate this picture, but if the problem can be transformed into a weakly nonlinear form then the resolution may still be explored in an approximate sense and used as a tool in the planning phase. The ideal situation is when previous seafloor estimates exist for the same region in which a new experiment with new geometry and configuration is being planned. For the scenario without previous results, a somewhat more ad-hoc approach can still compare changes in resolution across different seafloor models. This presentation demonstrates the technique for a synthetic problem involving a single stationary source and a single vertical array, but the formulation can be adapted to virtually any other sensor configuration as well.

The synaptic maintenance problem: membrane recycling, Ca2+ homeostasis and late onset degeneration.  

PubMed

Most neurons are born with the potential to live for the entire lifespan of the organism. In addition, neurons are highly polarized cells with often long axons, extensively branched dendritic trees and many synaptic contacts. Longevity together with morphological complexity results in a formidable challenge to maintain synapses healthy and functional. This challenge is often evoked to explain adult-onset degeneration in numerous neurodegenerative disorders that result from otherwise divergent causes. However, comparably little is known about the basic cell biological mechanisms that keep normal synapses alive and functional in the first place. How the basic maintenance mechanisms are related to slow adult-onset degeneration in different diseasesis largely unclear. In this review we focus on two basic and interconnected cell biological mechanisms that are required for synaptic maintenance: endomembrane recycling and calcium (Ca(2+)) homeostasis. We propose that subtle defects in these homeostatic processes can lead to late onset synaptic degeneration. Moreover, the same basic mechanisms are hijacked, impaired or overstimulated in numerous neurodegenerative disorders. Understanding the pathogenesis of these disorders requires an understanding of both the initial cause of the disease and the on-going changes in basic maintenance mechanisms. Here we discuss the mechanisms that keep synapses functional over long periods of time with the emphasis on their role in slow adult-onset neurodegeneration. PMID:23829673

An evaluation of independent consumer assistance centers on problem resolution and user satisfaction: the consumer perspective.  

PubMed

Individuals who wish to receive independent assistance to resolve access to care health problems have limited options. The Health Consumer Alliance (HCA) is an independent, coordinated effort of nine legal services organizations that provide free assistance to low-income health consumers in 10 California counties. The need for the HCA stems from the vast number of health consumers with unanswered questions and unresolved problems relating to access to care issues, among both insured and uninsured populations. However, little is known about the effectiveness of independent consumer assistance centers. This paper examines the effectiveness of a network of independent consumer assistance programs in resolving consumer problems and consumers' level of satisfaction with services received. As the project evaluators, we conducted telephone surveys with 1,291 users of the HCA to assess if this independent program resolved consumer problems, and to measure the level of satisfaction among HCA users. Specifically, we asked questions about the HCA's influence on problem resolution, consumer satisfaction, health insurance status and use of preventive care services. From 1997 to 2001, more than 46,000 consumers contacted the seven health consumer centers (HCCs). According to our sample of respondents, results show that the HCCs are an important resource for low-income Californians trying to access health care.

A high-resolution mapped grid algorithm for compressible multiphase flow problems  

NASA Astrophysics Data System (ADS)

We describe a simple mapped-grid approach for the efficient numerical simulation of compressible multiphase flow in general multi-dimensional geometries. The algorithm uses a curvilinear coordinate formulation of the equations that is derived for the Euler equations with the stiffened gas equation of state to ensure the correct fluid mixing when approximating the equations numerically with material interfaces. A ?-based and a ?-based model have been described that is an easy extension of the Cartesian coordinates counterpart devised previously by the author [30]. A standard high-resolution mapped grid method in wave-propagation form is employed to solve the proposed multiphase models, giving the natural generalization of the previous one from single-phase to multiphase flow problems. We validate our algorithm by performing numerical tests in two and three dimensions that show second order accurate results for smooth flow problems and also free of spurious oscillations in the pressure for problems with interfaces. This includes also some tests where our quadrilateral-grid results in two dimensions are in direct comparisons with those obtained using a wave-propagation based Cartesian grid embedded boundary method.

Problems associated with the preparation of whole mounts of cytoskeletons for high resolution electron microscopy.  

PubMed

The resolution currently available in both transmission and scanning electron microscopes is theoretically adequate to visualize the organization of the cytoskeleton at the supramolecular and macromolecular levels. However, achieving this resolution in practice requires that the methods used to prepare the specimens both preserve the structures of interest and render them visible for observation in the microscope without obscuring or altering them. In this paper we discuss our own and others efforts to develop methods to overcome several problems associated with preparing whole mounts of cytoskeletons for observation by electron microscopy. These problems include: controlling the degree to which cellular components are extracted; the effects of osmium tetroxide on the cytoskeleton; controlling and recognizing shrinkage and drying artifacts; the choice of a method of visualization; deposition of grain-free ultrathin films of metal; and interpreting the results. The standard procedure which we currently use consists of the following steps: growing cells on carbon-stabilized Formvar-coated gold electron microscope grids; extracting in 0.5% Triton X-100 detergent in a microtubule stabilizing buffer; postfixing in 2.5% glutaraldehyde in stabilizing buffer; freeze-drying; magnetron sputter-coating with 1.5 nm of tungsten; and observation by TEM, SEM, or STEM. Cytoskeletons prepared in this manner contain over 100 polypeptides and are composed of a complex three dimensional meshwork of clean, uniform filaments, the smallest of which are 7 nm in diameter. A structure resembling the microtrabecular lattice is present only if the cells are prefixed with a relatively long bifunctional protein crosslinking reagent prior to extraction with detergent.

A resolution of the ascertainment sampling problem. II. Generalizations and numerical results.  

PubMed Central

The ascertainment problem arises when families are sampled by a nonrandom process and some assumption about this sampling process must be made in order to estimate genetic parameters. Under classical ascertainment assumptions, estimation of genetic parameters cannot be separated from estimation of the parameters of the ascertainment process, so that any misspecification of the ascertainment process causes biases in estimation of the genetic parameters. Ewens and Shute proposed a resolution to this problem, involving conditioning the likelihood of the sample on the part of the data which is "relevant to ascertainment." The usefulness of this approach can only be assessed by examining the properties (in particular, bias and standard error) of the estimates which arise by using it for a wide range of parameter values and family size distributions and then comparing these biases and standard errors with those arising under classical ascertainment procedures. These comparisons are carried out in the present paper, and we also compare the proposed method with procedures which condition on, or ignore, parts of the data.

Application of CFD analysis to design support and problem resolution for ASRM and RSRM  

NASA Astrophysics Data System (ADS)

The use of Navier-Stokes CFD codes to predict the internal flow field environment in a solid rocket motor is a very important analysis element during the design phase of a motor development program. These computational flow field solutions uncover a variety of potential problems associated with motor performance as well as suggesting solutions to these problems. CFD codes have also proven to be of great benefit in explaining problems associated with operational motors such as in the case of the pressure spike problem with the STS-54B flight motor. This paper presents results from analyses involving both motor design support and problem resolution. The issues discussed include the fluid dynamic/mechanical stress coupling at field joints relative to significant propellant deformations, the prediction of axial and radial pressure gradients in the motor associated with motor performance and propellant mechanical loading, the prediction of transition of the internal flow in the motor associated with erosive burning, the accumulation of slag at the field joints and in the submerged nozzle region, impingement of flow on the nozzle nose, and pressure gradients in the nozzle region of the motor. The analyses presented in this paper have been performed using a two-dimensional axisymmetric model. Fluent/BFC, a three dimensional Navier-Stokes flow field code, has been used to make the numerical calculations. This code utilizes a staggered grid formulation along with the SIMPLER numerical pressure-velocity coupling algorithm. Wall functions are used to represent the character of the viscous sub-layer flow, and an adjusted k-epsilon turbulence model especially configured for mass injection internal flows, is used to model the growth of turbulence in the motor port. Conclusions discussed in this paper consider flow field effects on the forward, center, and aft propellant grains except for the head end star grain region of the forward propellant segment. The field joints and the submerged nozzle are discussed as well. Conclusions relative to both the design evaluation of the ASRM and the RSRM scenarios explaining the pressure spikes were based on the flow field solutions presented in this paper.

Approaching the Problem of Regional Climate Simulation through a Global, Multi-Resolution Modeling Approach: Successes and Challenges  

NASA Astrophysics Data System (ADS)

Global multi-resolution models of the atmosphere and ocean permit different spatial and temporal scales to be resolved in different parts of the simulation domain. In essence, these multi-resolution models allow regional climate processes to be directly simulated in user-specified locations while retaining a global modeling framework. As such, these models offer a means of studying regional climate change without the need for lateral boundary conditions and at reasonable computational expense. The Model for Prediction Across Scale (MPAS) is a global, multi-resolution modeling approach that is being used to develop atmosphere and ocean climate component models. Both the atmosphere and ocean models have been configured with enhanced resolution in specific regions of the atmosphere and ocean in order to resolve regional-scale processes. This talk will summarize the successes and challenges of these preliminary simulations. Conceptually, we separate these models into a dynamical core and physical parameterizations. We find that while challenges remain with the simulation of fluid dynamics, the modeling of the fluid flow on multi-resolution meshes is robust. Unfortunately, this is not the case for the physical parameterizations. Whether in the ocean or atmosphere, these parameterizations "feel" the changes in grid resolution and, thus, respond differently based on the local spatial resolution. While we explore this problem with only one multi-resolution model we fully expect the results to applicable to other multi-resolution models available today.

Using a metasynthesis approach, our aim was to articulate new insights relating to the most efficient and effective means of helping homeless women with substance abuse problems to enhance their well-being and become more stably housed. Distorted perceptions of competency, which are shaped by dysfunctional relationships and mental health problems, make it challenging for women with substance abuse problems to resolve homelessness. Women with particularly low or high levels of perceived competency tend to grapple with challenges related to structure and control, trust, and hopelessness. Therapeutic strategies for approaching these women include careful assessment, caring, personalized structure and control, development of interpersonal trust, instillation of hope, and the targeted use of psychotherapeutic agents and counseling. Framing care for homeless women within the context of perceived competency offers a new way of understanding their plight and shaping interventions to more expeditiously move them toward healthy and stable lives.

Retaining nurses through conflict resolution. Training staff to confront problems and communicate openly can improve the work climate.  

PubMed

The way nurses resolve conflict may be leading them to quit their jobs or leave the profession altogether. Conflict is inevitable in a dynamic organization. What is important is not to avoid conflict but to seek its resolution in a constructive manner. Organizational conflict is typically resolved through one of five strategies: withdrawal, force, conciliation, compromise, or confrontation. A recent study of nurses in three different hospitals showed that the approach they use most is withdrawal. This might manifest itself in a request to change shifts or assignments and may lead to a job change and, eventually, abandonment of the field altogether. Given this scenario, changing nurses' conflict resolution style may help administrators combat the nursing shortage. Healthcare organizations must examine themselves to determine why nurses so frequently use withdrawal; then they must restructure work relationships as needed. Next, organizations need to increase nurses' awareness of the problem and train them to use a resolution style more conducive to building stable relationships: confrontation. Staff should also be trained in effective communications skills to develop trust and openness in their relationships. PMID:10126220

S-Genius, a universal software platform with versatile inverse problem resolution for scatterometry  

NASA Astrophysics Data System (ADS)

S-Genius is a new universal scatterometry platform, which gathers all the LTM-CNRS know-how regarding the rigorous electromagnetic computation and several inverse problem solver solutions. This software platform is built to be a userfriendly, light, swift, accurate, user-oriented scatterometry tool, compatible with any ellipsometric measurements to fit and any types of pattern. It aims to combine a set of inverse problem solver capabilities — via adapted Levenberg- Marquard optimization, Kriging, Neural Network solutions — that greatly improve the reliability and the velocity of the solution determination. Furthermore, as the model solution is mainly vulnerable to materials optical properties, S-Genius may be coupled with an innovative material refractive indices determination. This paper will a little bit more focuses on the modified Levenberg-Marquardt optimization, one of the indirect method solver built up in parallel with the total SGenius software coding by yours truly. This modified Levenberg-Marquardt optimization corresponds to a Newton algorithm with an adapted damping parameter regarding the definition domains of the optimized parameters. Currently, S-Genius is technically ready for scientific collaboration, python-powered, multi-platform (windows/linux/macOS), multi-core, ready for 2D- (infinite features along the direction perpendicular to the incident plane), conical, and 3D-features computation, compatible with all kinds of input data from any possible ellipsometers (angle or wavelength resolved) or reflectometers, and widely used in our laboratory for resist trimming studies, etching features characterization (such as complex stack) or nano-imprint lithography measurements for instance. The work about kriging solver, neural network solver and material refractive indices determination is done (or about to) by other LTM members and about to be integrated on S-Genius platform.

Substation Reliability Centered Maintenance  

SciTech Connect

Substation Reliability Centered Maintenance (RCM) is a technique that is used to develop maintenance plans and criteria so the operational capability of substation equipment is achieved, restored, or maintained. The objective of the RCM process is to focus attention on system equipment in a manner that leads to the formulation of an optimal maintenance plan. The RCM concept originated in the airline industry in the 1970s and has been used since 1985 to establish maintenance requirements for nuclear power plants. The RCM process is initially applied during the design and development phase of equipment or systems on the premise that reliability is a design characteristic. It is then reapplied, as necessary, during the operational phase to sustain a more optimal maintenance program based on actual field experiences. The purpose of the RCM process is to develop a maintenance program that provides desired or specified levels of operational safety and reliability at the lowest possible overall cost. The objectives are to predict or detect and correct incipient failures before they occur or before they develop into major defects, reduce the probability of failure, detect hidden problems, and improve the cost-effectiveness of the maintenance program. RCM accomplishes two basic purposes: (1) It identifies in real-time incipient equipment problems, averting potentially expensive catastrophic failures by communicating potential problems to appropriate system operators and maintenance personnel. (2) It provides decision support by recommending, identifying, and scheduling preventive maintenance. Recommendations are based on maintenance criteria, maintenance history, experience with similar equipment, real-time field data, and resource constraints. Hardware and software are used to accomplish these two purposes. The RCM system includes instrumentation that monitors critical substation equipment as well as computer software that helps analyze equipment data.

An examination of several high resolution schemes applied to complex problems in high speed flows  

NASA Astrophysics Data System (ADS)

A comparative study of five upwind schemes was performed to evaluate their ability to accurately model the convective fluxes of the Euler equations for problems containing complex shock structure. The schemes investigated used a variety of Reimann solvers and obtained higher order accuracy using either a MUSCL or non-MUSCL approach. The MUSCL-type schemes included the flux vector split formulations of Steiger-Warming and van Leer and the flux difference split approach of Roe. The Non-MUSCL schemes included the Symmetric and Upwind TVD methods of Yee, and Harten and Yee. Two central difference schemes provide a basis for the evaluation of these upwind methods. The comparison was performed using identical meshes and convergence criteria. In a supersonic blunt body flow, all the upwind schemes displayed comparably resolved bow shocks, independent of free stream Mach number. However, a complex type IV shock on cowl lip example pointed out significant differences in the accuracy and convergence behavior of the schemes. A comparison of the flow structure shown by the various algorithms on identical grids indicated that the discrete solutions obtained with Upwind TVD and Roe flux difference splitting were the least diffusive of the upwind methods considered.

Maintenance scheduling

The requirements for daily, weekly, monthly and overtime maintenance scheduling of coal-fired power plants are discussed. It is concluded that maintenance scheduling is as essential as the physical performance of the work itself. By prescheduling maintenance, the optimum utilization of manpower and equipment reliability will be obtained. Spare parts, special tools and service engineer requirements can be anticipated with reasonable scheduling. Meetings are a distasteful word in anyone's vocabulary. However, close communication, between operation and maintenance, is a must to insure that both departments are aware of the job status and progress. Improved communication and scheduling of equipment maintenance can help break down the barrier that has developed between the two Departments.

Solar systems maintenance  

SciTech Connect

This article examines several hundred solar systems, especially those in the HUD Solar Residential Demonstration Program, in order to show that solar energy systems have all the maintenance requirements of non-solar HVAC systems, as well as additional ones peculiar to solar systems. The additional maintenance requirements occur because of the special features in solar systems, such as the collector panels, the conditions to which the heat-transfer fluid can be subjected, and the special corrosion problems. It is concluded that the simplest systems are the easiest to maintain; regular inspection and maintenance of a solar system can help prevent major expenses for repair and replacement; the ease of maintenance should be a factor considered during design and installation of a solar system; it is important to include adequate measuring instruments in a solar system, especially thermometers, flowmeters, and pressure gages; in liquid-based solar systems, the major cause of problems is corrosion which requires special attention; in air solar systems, the main problem is air leakage, which is not easily detected directly and generally shows itself in terms of poor performance; and site-built and site-assembled solar collectors are generally high-maintenance parts of a solar system and should be inspected regularly.

Problems in hydrostatic transmission maintenance are identified and ways of overcoming them are suggested. It is found that problems arise from lack of lubrication, impurities in the oil, and cavitation at the pump and at the motor. It is under suggested that under nonsevere operating conditions, oil and filter should be changed every year, or every 1500 to 2000 hr running time. Under severe operating conditions or in dusty environments, the interval should be every 6 months or 1000 hr.

Dual effect of platelet lysate on human articular cartilage: a maintenance of chondrogenic potential and a transient proinflammatory activity followed by an inflammation resolution.  

PubMed

Platelet-rich plasma (PRP), a cocktail of platelet growth factors and bioactive proteins, has been proposed as a therapeutic agent to restore damaged articular cartilage. We report the biological effect of the platelet lysate (PL), a PRP derivative, on primary human articular chondrocytes cultured under both physiological and inflammatory conditions. When added to the culture medium, PL induced a strong mitogenic response in the chondrocytes. The in vitro expanded cell population maintained a chondrogenic redifferentiation potential as revealed by micromass culture in vitro and ectopic cartilage formation in vivo. Further, in chondrocytes cultured in the presence of the proinflammatory cytokine interleukin-1? (IL-1?), the PL induced a drastic enhancement of the synthesis of the cytokines IL-6 and IL-8 and of neutrophil-gelatinase associated lipocalin, a lipocalin expressed during chondrocyte differentiation and inflammation. These events were mediated by the p38 MAP kinase and NF-?B pathways. We observed that inflammatory stimuli activated phospo-MAP kinase-activated protein kinase 2, a direct target of p38. The proinflammatory effect of the PL was a transient phenomenon; after an initial upregulation, we observed significant reduction of the NF-?B activity together with the repression of the inflammatory enzyme cyclooxygenase-2. Moreover, the medium of chondrocytes cultured in the simultaneous presence of PL and IL-1?, showed a significant enhancement of the chemoattractant activity versus untreated chondrocytes. Our findings support the concept that the platelet products have a direct beneficial effect on articular chondrocytes and could drive in sequence a transient activation and the resolution of the inflammatory process, thus providing a rational for their use as therapeutic agents in cartilage inflammation and damage.

Reinforcement Learning for Scheduling of Maintenance  

NASA Astrophysics Data System (ADS)

Improving maintenance scheduling has become an area of crucial importance in recent years. Condition-based maintenance (CBM) has started to move away from scheduled maintenance by providing an indication of the likelihood of failure. Improving the timing of maintenance based on this information to maintain high reliability without resorting to over-maintenance remains, however, a problem. In this paper we propose Reinforcement Learning (RL), to improve long term reward for a multistage decision based on feedback given either during or at the end of a sequence of actions, as a potential solution to this problem. Several indicative scenarios are presented and simulated experiments illustrate the performance of RL in this application.

Numerical resolution on a massively parallel computer of a test problem in methodology using a domain decomposition algorithm  

NASA Astrophysics Data System (ADS)

A discretization of the Polar Factorization (PF) in the form of an assignmnt problem has been introduced and we showed its consistency. Domain decomposition techniques for the continuous and discrete problems have also been studied and used to construct a highly parallel algorithm well designed for a SIMD massively parallel computer. Given a discretization of a vector field, it performs a permutation of these discrete values. The output is consistent with the gradient of the convex potential associated by the PF theorem with the initial vector field. This algorithm has been implemented on the Connection Machine to achieve the Lagrangian to Eulerian conversion of Cullen's method for the Semi-Geostrophic (S-G) deformation model. We present in section 1 the S-G equations, the deformation model and introduce Cullen's principle and method of solution. Section 2 is an overview of PF theory and presents our algorithm. The test problem (TP) is treated in section 3 where the exact solutions obtained using a conservation law formulation are displayed together with numerical results produced by our algorithm.

Frequency-domain calculation of the self-force: The high-frequency problem and its resolution  

SciTech Connect

The mode-sum method provides a practical means for calculating the self-force acting on a small particle orbiting a larger black hole. In this method, one first computes the spherical-harmonic l-mode contributions F{sub l}{sup {mu}} of the 'full-force' field F{sup {mu}}, evaluated at the particle's location, and then sums over l subject to a certain regularization scheme. In the frequency-domain variant of this procedure the quantities F{sub l}{sup {mu}} are obtained by fully decomposing the particle's self-field into Fourier-harmonic modes lm{omega}, calculating the contribution of each such mode to F{sub l}{sup {mu}}, and then summing over {omega} and m for given l. This procedure has the advantage that one only encounters ordinary differential equations. However, for eccentric orbits, the sum over {omega} is found to converge badly at the particle's location. This problem (reminiscent of the familiar Gibbs phenomenon of Fourier analysis) results from the discontinuity of the time-domain F{sub l}{sup {mu}} field at the particle's worldline. Here we propose a simple and practical method to resolve this problem. The method utilizes the homogeneous modes lm{omega} of the self-field to construct F{sub l}{sup {mu}} (rather than the inhomogeneous modes, as in the standard method), which guarantees an exponentially fast convergence to the correct value of F{sub l}{sup {mu}}, even at the particle's location. We illustrate the application of the method with the example of the monopole scalar-field perturbation from a scalar charge in an eccentric orbit around a Schwarzschild black hole. Our method, however, should be applicable to a wider range of problems, including the calculation of the gravitational self-force using either Teukolsky's formalism, or a direct integration of the metric perturbation equations.

Establishing maintenance performance indicators  

SciTech Connect

Maintenance Performance Indicators (PI) specify where the maintenance department is and which direction it is going allowing for a quick and accurate assessment of the performance of the Maintenance Management Program (MMP). Establishing PI`s for the maintenance department will allow a measure of productivity and a means of feedback for methods improvement. Effective performance of the maintenance department directly effects plant profitability. Improvements in the quality and productivity of the maintenance work force will significantly reduce maintenance costs. The level of performance attained by the maintenance work force is usually guessed at. Guessing will not identify areas needing improvement or help to initiate a corrective action. Maintenance PI`s are required for maintenance departments whose goal is to control maintenance costs while increasing productivity. The application of basic statistical methods will allow a maintenance department to know where they are and which direction they are going. The data presented in this paper is a representation of indicators used in industry as well as developed indicators to establish a complete maintenance performance indicator program. The methodology used in developing this program can be used as a way to manage a cost effective maintenance management program.

The maintenance revolution  

SciTech Connect

The ultimate goal of EPRI`s maintenance-related research is to help utilities lower costs by optimizing their overall maintenance process. The process begins with a reliability-centered maintenance (RCM) analysis of plant systems to determine critical system components. Maintenance intervals for these components are then set on the basis either of fixed time intervals or of equipment condition as determined by predictive maintenance (PDM) diagnostic techniques. Finally, a self-improving, `living` maintenance program is continually updated by feedback of information from subsequent maintenance experience. This paper traces the history of RCM and discusses the reduction of implementation costs and broader applications. It also addresses the progress in predictive maintenance, nuclear PDM applications, new diagnostic technologies, and, applications to power delivery.

Maintenance as a safety issue.  

PubMed

Because safety is related to electrical power systems maintenance, it seems reasonable to assume there could be legal issues if maintenance is not performed. OSHA has not yet taken the stand that not performing maintenance as required by the manufacturer, NFPA 70B, or ANSI/NETA MTS-07 constitutes a willful violation. OSHA defines a willful citation as one where: "the employer knowingly commits with plain indifference to the law. The employer either knows that what he or she is doing constitutes a violation, or is aware that a hazardous condition existed and made no reasonable effort to eliminate it". However, NFPA 70E 2009 requires this maintenance, and OSHA has stated on its Web site that NFPA 70E is "a guide for meeting the requirements of the OSHA electrical regulations". In addition, federal courts have found that NFPA 70E is "standard industry practice." Once a company receives and accepts a willful citation, especially if received as the result of an accident investigation, its worker's compensation protection no longer shields it. One definition given by a trial attorney for a willful citation was that it is equal to negligent behavior. Be smart: Maintain that equipment and save yourself major problems, including unscheduled shutdowns and possible litigation. PMID:19025196

Industrial Maintenance Strategies  

SciTech Connect

Industrial plants have become more complex due to technological advancement. This has made the task of maintenance more difficult. The maintenance costs in terms of resources and downtime loss are so high that maintenance function has become a critical factor in a plant's profitability. Industry should devote as much forethought to the management of maintenance function as to production. Maintenance has grown from an art to a precise, technical engineering science. Planning, organizing scheduling and control of maintenance using modern techniques pays dividends in the form of reduced costs and increased reliability. The magnitude and the dimension of maintenance have multiplied due to development in the engineering technologies. Production cost and capacities are directly affected by the breakdown time. Total operating cost including the maintenance cost plays an important role in replacement dimension. The integrated system approach would bring forth the desired results of high maintenance standards. The standards once achieved and sustained, would add to the reliability of the plan and relieve heavy stresses and strains on the engineering logistic support. (author)

A Study on Machine Maintenance Scheduling Using Distributed Cooperative Approach

In this study, we propose a distributed cooperative scheduling method, and apply the method into a machine maintenance scheduling problem in re-entrant production systems. As one of the distributed cooperative scheduling methods, we focus on Lagrangian decomposition and coordination (LDC) method, and formulate the machine maintenance scheduling problem with LDC so as to improve computational efficiency by decomposing an original scheduling problem into several sub-problems. The derived solutions by solving the decomposed dual problem are converted into feasible solutions with a heuristic procedure applied in this study. The proposed approach regards maintenance as job with starting and finishing time constraints, so that product and maintenance schedule can realize proper maintenance operations without losing productivity. We show the effectiveness of the proposed method in several simulation experiments.

Resolution of numerical control machine tool modification problems using a symbiosis of machinery diagnostics, modal analysis, structural dynamics modification and acoustic intensity analysis  

SciTech Connect

A multi-million dollar retrofit project was initiated to update a number of older numerical control machine tools. The retrofit replaced the servo control systems, the indexing motors, drive systems and spindle motor. One machine was upgraded as a prototype, but several dynamic problems in both the indexing systems and spindle drive became apparent. These dynamic problems were unacceptable in their effect on machining accuracy. Acoustic intensity measurements were used to pinpoint the source of an irritating 3 KHz tone. This tone indicated a significant amount of energy resulting in a high displacement in the indexing motors. Frequency response measurements of the motor response vs the power supply input quantified the motor problem and the acoustic levels. Modal analysis was applied to the axial resonances of the index motors to determine the response of the mechanical coupling and run up/down tests were used to determine the spindle motor drive problems. 8 figs.

Therefore, many approaches focused on automation of various aspects of compliance problem, e.g., compliance verification. Such techniques allow localizing the problem within the process model. However, they are not able to resolve the violations. In this paper we address the problem of (semi) automatic violation resolution, addressing violations of execution ordering compliance rules. We build upon previous work in categorizing the violations into types and employ automated planning to ensure compliance. The problem of choosing the concrete resolution strategy is addressed by the concept of context.

Impact of Pharmaceutical Care interventions in the identification and resolution of drug-related problems and on quality of life in a group of elderly outpatients in Ribeir?o Preto (SP), Brazil  

PubMed Central

Objective To evaluate the impact of a Pharmaceutical Care service in the identification and resolution of drug-related problems (DRPs) and in quality of life (QoL) of a group of elderly outpatients with chronic health conditions. Methods 30 outpatients (aged 60–75-years old) were followed between August 2003 and July 2004 at a primary health care unit in Ribeirão Preto (SP), Brazil. Patients were scheduled monthly to meet with the researcher, who provided Pharmaceutical Care service (the intervention). Through Pharmaceutical Care, the pharmacist worked with the patient and other care providers to improve outcomes of drug therapy through focused education, care planning, and monitoring. Intervention outcomes were the number of DRPs prevented or resolved, and the impact on QoL. The Short Form-36 health survey was used to measure changes in QoL. Results The mean age of patients was 66 ± 5 years, 21 of whom had low literacy. During the study, 92 DRP were identified, 3.0 ± 1.5 problems per patient. By the end of the study, the interventions solved 69% of actual DRP and prevented 78.5% potential DRP. In addition, QoL showed improvement in 22 patients after DRP resolution or prevention. Conclusion Despite the limitations in this study that may affect generalizability of the results, this study demonstrates that humanistic and behavioral interventions based on the Pharmaceutical Care model were capable in reducing DRPs, and improve QoL in patients.

Exact Tensor Hypercontraction: A Universal Technique for the Resolution of Matrix Elements of Local Finite-Range N-Body Potentials in Many-Body Quantum Problems  

NASA Astrophysics Data System (ADS)

Configuration-space matrix elements of N-body potentials arise naturally and ubiquitously in the Ritz-Galerkin solution of many-body quantum problems. For the common specialization of local, finite-range potentials, we develop the exact tensor hypercontraction method, which provides a quantized renormalization of the coordinate-space form of the N-body potential, allowing for a highly separable tensor factorization of the configuration-space matrix elements. This representation allows for substantial computational savings in chemical, atomic, and nuclear physics simulations, particularly with respect to difficult “exchangelike” contractions.

This article is an interview with Tim Tulon, formerly maintenance superintendent, and now operations manager, of Commonwealth Edison Company`s Byron nuclear power plant. This plant has two PWR Westinghouse reactors. The interview looks at the question of how this plant addresses problems of plant maintenance, and in particular how it is positioning itself with regard to the new maintenance rule from the NRC. Tulon indicates that the major upgrade in maintenance training at present is increased emphasis on addressing what the workers perceive as weaknesses in their skills. New simulators have been added for increased off line training, in particular for reactor operators and instrument techs.

Conflict resolution.  

PubMed

The sooner conflict is identified and confronted, the more quickly it can be resolved (and the sooner, the better). When this is accomplished calmly and objectively, many areas of conflict will be eliminated. Addressing conflict as it arises also sends a clear message to the team that the practice seeks resolution, not punishment or negative consequences. In addition, the dentist and the office manager need to lead by example by avoiding gossip and encouraging open communication. The goal is to go from a parent-child relationship with the dental team to an adult-adult relationship using this series of managerial conflict resolution steps. PMID:16570474

Paranal maintenance and CMMS experience  

NASA Astrophysics Data System (ADS)

During the last four years of operations, low technical downtime has been one of the relevant records of the Paranal Observatory. From the beginning of the Very Large Telescope (VLT) project, European Southern Observatory (ESO) has considered the implementation of a proper maintenance strategy a fundamental point in order to ensure low technical down time and preserve the Observatory's assets. The implementation of the maintenance strategy was based on the following aspects: - Strong maintenance sense during the design stage. Line Replacement Unit (LRU) concept, standardization and modularity of the Observatory equipment - Creation of a dedicated team for Maintenance - The implementation of a Computerized Maintenance Management System After four operational years, the result of these aspects has exceeded the expectations; the Observatory has been operating with high availability under a sustainable strategy. The strengths of the maintenance strategy have been based on modern maintenance concepts applied by regular production companies, where any minute of down time involves high cost. The operation of the actual Paranal Maintenance System is based mainly on proactive activities, such as regular inspections, preventive maintenance (PM) and predictive maintenance (PdM) plans. Nevertheless, it has been necessary to implement a strong plan for corrective maintenance (CM). The Spare Parts Strategy has also been an important point linked to the Maintenance Strategy and CMMS implementation. At present, almost 4,000 items related to the Observatory spare parts are loaded into the CMMS database. Currently, we are studying the implementation of a Reliability Centered Maintenance (RCM) project in one of our critical systems The following document presents the actual status of the Paranal Maintenance Strategy and which have been the motivations to implement the established strategy.

Issues in maintenance and repairs of wheelchairs: A pilot study.  

PubMed

In this pilot study, we assessed wheelchair durability and its effect on user satisfaction. Specifically, we examined the characteristics of the participants' wheelchairs, the types of maintenance and repairs completed, and whether the participants' satisfaction was affected by problems with their wheelchairs. A convenience sample of 130 participants who used wheelchairs as their primary means of mobility was recruited. Participants completed a questionnaire about their wheelchairs, the maintenance and repair history, and their satisfaction levels. Results showed that 26% of the participants had completed a wheelchair repair in the past 6 months, 16% had completed general maintenance, and 27% had completed tire repairs. Neither hours of wheelchair use nor wheelchair age affected repair or maintenance frequency. Participants were generally satisfied with their wheelchairs. Better understanding of wheelchair maintenance and repair issues will guide improvements in wheelchair design and enhance the community participation of individuals who use wheelchairs.

Towards automated traceability maintenance  

PubMed Central

Traceability relations support stakeholders in understanding the dependencies between artifacts created during the development of a software system and thus enable many development-related tasks. To ensure that the anticipated benefits of these tasks can be realized, it is necessary to have an up-to-date set of traceability relations between the established artifacts. This goal requires the creation of traceability relations during the initial development process. Furthermore, the goal also requires the maintenance of traceability relations over time as the software system evolves in order to prevent their decay. In this paper, an approach is discussed that supports the (semi-) automated update of traceability relations between requirements, analysis and design models of software systems expressed in the UML. This is made possible by analyzing change events that have been captured while working within a third-party UML modeling tool. Within the captured flow of events, development activities comprised of several events are recognized. These are matched with predefined rules that direct the update of impacted traceability relations. The overall approach is supported by a prototype tool and empirical results on the effectiveness of tool-supported traceability maintenance are provided.

Assumption truth maintenance in model-based ATR algorithm design  

NASA Astrophysics Data System (ADS)

In a given approach to automatic target recognition (ATR) algorithm design, an underlying network of assumptions provides computational and conceptual efficiency. This network includes concrete assumptions about the physical characteristics of the real-world scene and abstract assumptions about knowledge acquisition and representation. A facility for the identification and tracking of assumptions in dynamic systems is critical for algorithm design and performance evaluation purposes. The intersection of assumptions at a designated stage of the target recognition process defines the valid domain of application of the ATR system. An approach to assumption truth maintenance for application to complex, visual pattern recognition systems is described. The types of assumptions made in key-feature, model-based ATR systems are systematically identified, from the low-level pixel domain to the high-level mission statement. The approach permits the tracking of algorithm assumptions as they propagate through the pattern recognition process and provides for belief formation and revision to maintain consistency. The approach is demonstrated on a prototype set of infrared test imagery at varying levels of resolution and signal-to-noise ratio, representative of the given problem domain.

Risk-based maintenance modeling. Prioritization of maintenance importances and quantification of maintenance effectiveness  

SciTech Connect

This report describes methods for prioritizing the risk importances of maintenances using a Probabilistic Risk Assessment (PRA). Approaches then are described for quantifying their reliability and risk effects. Two different PRA importance measures, minimal cutset importances and risk reduction importances, were used to prioritize maintenances; the findings show that both give similar results if appropriate criteria are used. The justifications for the particular importance measures also are developed. The methods developed to quantify the reliability and risk effects of maintenance actions are extensions of the usual reliability models now used in PRAs. These extended models consider degraded states of the component, and quantify the benefits of maintenance in correcting degradations and preventing failures. The negative effects of maintenance, including downtimes, also are included. These models are specific types of Markov models. The data for these models can be obtained from plant maintenance logs and from the Nuclear Plant Reliability Data System (NPRDS). To explore the potential usefulness of these models, the authors analyzed a range of postulated values of input data. These models were used to examine maintenance effects on a components reliability and performance for various maintenance programs and component data. Maintenance schedules were analyzed to optimize the component`s availability. In specific cases, the effects of maintenance were found to be large.

To maintain linear DNA genomes, organisms have evolved numerous means of solving problems associated with DNA ends (telomeres), including telomere-associated retrotransposons, palindromes, hairpins, covalently bound proteins and the addition of arrays of simple DNA repeats. Telomeric arrays can be maintained through various mechanisms such as telomerase activity or recombination. The recombination-dependent maintenance pathways may include telomeric loops (t-loops) and telomeric circles (t-circles). The potential involvement of t-circles in telomere maintenance was first proposed for linear mitochondrial genomes. The occurrence of t-circles in a wide range of organisms, spanning yeasts, plants and animals, suggests the involvement of t-circles in many phenomena including the alternative-lengthening of telomeres (ALT) pathway and telomere rapid deletion (TRD). In this Perspective, we summarize these findings and discuss how t-circles may be related to t-loops and how t-circles may have initiated the evolution of telomeres. PMID:19809492

For some years now, Duke Power Company has been working to incorporate exposure control considerations into its maintenance planning. THe ultimate intent is to make shutdown maintenance planners primarily responsible or ALARA planning down to the job level, rather than Health Physics. The reason--improvements in the efficiency of shutdown maintenance and hence capacity factors can only come from complete and effective planning, including ALARA. This paper reports that as one step in this direction, the Maintenance ALARA Planning Flowchart was prepared and issued in February 1988. This flowchart will allow planners to prepare job packages that include the HP/ALARA aspects for all radiation work. Planners enter the Maintenance Flowchart for all radiation work during the initial planning stage.

Practical considerations in developing an instrument-maintenance plan--  

SciTech Connect

The author develops a general set of considerations to explain how a consistent, well-organized, prioritized, and adequate time-allowance program plan for routine maintenance can be constructed. The analysis is supplemented with experience from the high flux isotope reactor (HFIR) at US Oak Ridge National Laboratory (ORNL). After the preventive maintenance (PM) problem was defined, the instruments on the schedule were selected based on the manufacturer's design specifications, quality-assurance requirements, prior classifications, experiences with the incidence of breakdowns or calibration, and dependencies among instruments. The effects of repair error in PM should be also studied. The HFIR requires three full-time technicians to perform both PM and unscheduled maintenance. A review is presented of concepts from queuing theory to determine anticipated breakdown patterns. In practice, the pneumatic instruments have a much longer lifetime than the electric/electronic instruments on various reactors at ORNL. Some special considerations and risk aversion in choosing a maintenance schedule.

Sirtuins, Tissue Maintenance, and Tumorigenesis  

PubMed Central

Aging is a degenerative process resulting in compromised tissue maintenance and increased susceptibility to diseases, such as cancer. Recent advancements support the notion that aging is a highly regulated process governed by evolutionarily conserved pathways. In mammals, tissue-specific adult stem cells (ASCs) persist throughout the lifetime to maintain and repair tissues. While reduced ASC self-renewal is thought to contribute to compromised tissue maintenance, increased self-renewal of cancer stem cells (CSCs) may lead to tumorigenesis. It is speculated that genetic regulators of aging, such as sirtuins, are likely to impinge upon the ASC compartments to regulate tissue maintenance and tumorigenesis. In this review, we discuss the emerging evidence linking sirtuins to normal and malignant ASC self-renewal, tissue maintenance, and tumorigenesis.

High resolution telescope  

NASA Astrophysics Data System (ADS)

A large effective-aperture, low-cost optical telescope with diffraction-limited resolution enables ground-based observation of near-earth space objects. The telescope has a non-redundant, thinned-aperture array in a center-mount, single-structure space frame. It employs speckle interferometric imaging to achieve diffraction-limited resolution. The signal-to-noise ratio problem is mitigated by moving the wavelength of operation to the near-IR, and the image is sensed by a Silicon CCD. The steerable, single-structure array presents a constant pupil. The center-mount, radar-like mount enables low-earth orbit space objects to be tracked as well as increases stiffness of the space frame. In the preferred embodiment, the array has elemental telescopes with subaperture of 2.1 m in a circle-of-nine configuration. The telescope array has an effective aperture of 12 m which provides a diffraction-limited resolution of 0.02 arc seconds. Pathlength matching of the telescope array is maintained by an electro-optical system employing laser metrology. Speckle imaging relaxes pathlength matching tolerance by one order of magnitude as compared to phased arrays. Many features of the telescope contribute to substantial reduction in costs. These include eliminating the conventional protective dome and reducing on-site construction activities. The cost of the telescope scales with the first power of the aperture rather than its third power as in conventional telescopes.

A combinational theory for maintenance of sex  

PubMed Central

Sexual reproduction implies high costs, but it is difficult to give evidence for evolutionary advantages that would explain the predominance of meiotic sex in eukaryotes. A combinational theory discussing evolution, maintenance and loss of sex may resolve the problem. The main function of sex is the restoration of DNA and consequently a higher quality of offspring. Recombination at meiosis evolved, perhaps, as a repair mechanism of DNA strand damages. This mechanism is most efficient for DNA restoration in multicellular eukaryotes, because the initial cell starts with a re-optimized genome, which is passed to all the daughter cells. Meiosis acts also as creator of variation in haploid stages, in which selection can purge most efficiently deleterious mutations. A prolonged diploid phase buffers the effects of deleterious recessive alleles as well as epigenetic defects and is thus optimal for prolonged growth periods. For complex multicellular organisms, the main advantage of sexuality is thus the alternation of diploid and haploid stages, combining advantages of both. A loss of sex is constrained by several, partly group-specific, developmental features. Hybridization may trigger shifts from sexual to asexual reproduction, but crossing barriers of the parental sexual species limit this process. For the concerted break-up of meiosis-outcrossing cycles plus silencing of secondary features, various group-specific changes in the regulatory system may be required. An establishment of asexuals requires special functional modifications and environmental opportunities. Costs for maintenance of meiotic sex are consequently lower than a shift to asexual reproduction.

Recirculation control valve replacement cuts maintenance costs  

SciTech Connect

This article describes how replacement of boiler feed pump recirculation control valves solves a maintenance problem on Baldwin Unit 3. All three of Illinois Power`s Baldwin power plant units had the same boiler feed pump (BFP) valve design when they went into commercial operation. The original BFP recirculation valves were a top-guided plug, single-port cage design using a tapered plug and seat arrangement. This design failed in Unit 1 during the first year of operation, so a redesigned set of internals was installed in 1973. The new internals used a drilled-hole cage and were designed to resist cavitation and erosion. This same design was initially installed in the Unit 2 and Unit 3 valves. During initial unit startup and throughout the years, cavitation and erosion of the valve internals resulted in leaks.

Assessing maintenance of evaporative cooling systems in legionellosis outbreaks.  

PubMed

This study was designed to conduct systematic reviews of existing evaporative cooling system maintenance guidelines and of published Legionnaires' disease outbreaks to determine what, if any, maintenance practices were in place at the time of the disease outbreaks and then to contrast the reported practices with the published guidelines for evaporative cooling systems. For the first review, similarities in the reported recommendations were assessed; in the second review, any reported information about the state of the evaporative cooling system during the outbreak investigation was summarized. The systematic reviews yielded 38 current guidelines for evaporative cooling systems and 38 published outbreak investigations. The guidelines varied regarding the recommended type and dose of biocides, frequency of general inspections and total system maintenance, the preferred disinfection and cleaning procedures when testing a system for microbiological contamination, the type and frequency of testing procedures, and interpretation of test results. Overall, the maintenance guidelines did not contain sufficiently detailed procedures to prevent the problems that were observed in the outbreak investigations. These maintenance procedures included lack or improper use of a biocide; infrequent testing for microbiological contamination; improper use or maintenance of drift eliminators; and lack of a total system cleaning within 6 months of the outbreak for cooling systems that were either under continuous use, recently started up, or frequently switched on and off. This study suggests that more specific and standardized maintenance guidelines for the control of Legionella bacteria are needed and that these guidelines must be properly implemented to help reduce further Legionnaires' disease outbreaks associated with evaporative cooling systems.

KINOFORM LENSES - TOWARD NANOMETER RESOLUTION.  

SciTech Connect

While hard x-rays have wavelengths in the nanometer and sub-nanometer range, the ability to focus them is limited by the quality of sources and optics, and not by the wavelength. A few options, including reflective (mirrors), diffractive (zone plates) and refractive (CRL's) are available, each with their own limitations. Here we present our work with kinoform lenses which are refractive lenses with all material causing redundant 2{pi} phase shifts removed to reduce the absorption problems inherently limiting the resolution of refractive lenses. By stacking kinoform lenses together, the effective numerical aperture, and thus the focusing resolution, can be increased. The present status of kinoform lens fabrication and testing at Brookhaven is presented as well as future plans toward achieving nanometer resolution.

Maintenance of defibrillators in a state of readiness.  

PubMed

Since 1984, the US Food and Drug Administration (FDA) has utilized the Medical Device Reporting system as a mechanism for reporting adverse incidents associated with the use of medical devices, including external defibrillators. The frequency and content of these reports prompted an FDA-conducted five-state study of defibrillator-user training and maintenance practices for both devices and batteries. The study also included inspection and testing of defibrillators and batteries to assess their state of maintenance. A detailed review of the reports and of the five-state data confirmed that in the majority of cases, adverse incidents were related to improper defibrillator operation and maintenance, prompting the FDA Center for Devices and Radiological Health to launch an educational effort directed toward those who operate and maintain defibrillators. Proper maintenance of batteries (both nickel-cadmium and sealed lead-acid) was a major component of the educational thrust, because battery failure was identified as a recurrent and preventable problem. In an effort to correct the diverse types of incidents being reported, checklists were developed by the FDA for both manual and automated defibrillators. The checklists are designed to cover the spectrum of reported problems related to both device and user. The advent of more stringent FDA adverse incident-reporting regulations, coupled with increased use of defibrillators in diverse settings with varying usage frequencies, would seem to give a major impetus to the regular use of these checklists wherever defibrillators are employed.

Mining Surveillance and Maintenance Dollars  

SciTech Connect

Accelerating site cleanup to reduce facility risks to the workers, the public and the environment during a time of declining federal budgets represents a significant technical and economic challenge to U.S. Department of Energy (DOE) Operations Offices and their respective contractors. A significant portion of a facility's recurring annual expenses are associated with routine, long-term surveillance and maintenance (S&M) activities. However, ongoing S&M activities do nothing to reduce risks and basically spend money that could be reallocated towards facility deactivation. This paper discusses the background around DOE efforts to reduce surveillance and maintenance costs, one approach used to perform cost reviews, lessons learned from field implementation and what assistance is available to assist DOE sites in performing these evaluations.

Personal Health Maintenance for Children  

PubMed Central

The foundations for lifelong responsibility for personal health maintenance are laid down in childhood. Personal health maintenance for children is important for a healthy childhood, for a healthy adulthood and for the development of positive values about health, personal health responsibility and the use of health services. Present knowledge in this area is weak but growing. Five areas of development are highlighted: (1) the cognitive understanding of health and disease, (2) a psychological sense of control over health, (3) parental and media influences on health behaviors, (4) school health education and (5) training by health professionals about self-management of childhood illness and health services usage patterns. Implications for current practice are developed.

[Family ties and maintenance obligation].  

PubMed

Maintenance obligation is a question frequently addressed in gerontology as an elderly person prepares to enter an institution. Its implementation is a source of conflict within families as well as with professionals involved in these situations. This administrative process, generally long and complex, can shatter family ties and lengthen the time required to obtain support thereby delaying admission to the institution. To tackle these issues, professionals from the Paris Saint-Joseph hospital group have set up meetings bringing together social services, medical services and management representatives. These multi-disciplinary consultations have highlighted the need for management to work with the families of hospitalised patients to remind them of the maintenance obligation in a framework of mediation.

Demonstration of reliability centered maintenance  

SciTech Connect

Southern California Edison Company (SCE) has completed a two year demonstration of Reliability Centered Maintenance (RCM) at San Onofre Nuclear Generating Station (SONGS) Unit 2. The demonstration involved the application of detailed RCM analysis to 12 plant systems and the implementation of the preventive maintenance (PM) and testing recommendations from these analyses. Other tasks in support of the successful application and implementation included (1) the selection and prioritization of systems for RCM analysis, (2) employing RCM as the technical basis for technical specification change, and (3) development of an RCM living program. The overall objective of the project is to demonstrate that RCM can be cost-effectively performed in a nuclear plant environment. This report describes in detail the methodologies which evolved at SONGS to perform the above tasks. This report summarizes the recommendations from the analyses which include task deletions, task additions, task modifications, and design changes. A significant portion of these recommendations have been evaluated at SONGS, and the status of task implementation is described herein. Significant maintenance man-hour savings are documented on systems for which the recommendations have been evaluated and implemented. Insights of value for future RCM applications are enumerated. Finally, plans for continued use of RCM at SONGS are confirmed and described. 12 refs., 17 figs., 2 tabs.

Under Round 4 of the U.S. Department of Energy`s (DOE) Clean Coal Technology program, New York State Electric & Gas Corporation (NYSEG), in partnership with Saarberg-Holter-Umwelttechnik (SHU), Consolidation Coal Company and Stebbins Engineering and Manufacturing Company, has retrofitted a formic acid enhanced forced oxidation wet limestone scrubber on Units I and 2 at the Milliken Steam Electric Station. Units I and 2 are 1950s vintage Combustion Engineering tangentially fired pulverized coal units, which are rated at nominal 150 MW each and operate in balanced draft mode. The Flue Gas Desulfurization (FGD) system for Unit 2 was placed into operation in January 1995 and the Unit I system in June 1995. The project incorporates several unique aspects: low pH operation; a ceramic tile-lined cocurrent/countercurrent, split module absorber; a wet stack supported on the roof of the FGD building; and closed loop, zero liquid discharge operation that produces commercial grade gypsum and calcium chloride brine. The project objectives include 98% SO{sub 2} removal efficiency while burning high sulfur coal, the production of marketable byproducts to minimize solid waste disposal, zero wastewater discharge, space-saving design, and minimization of maintenance requirements of a wet scrubber. The paper provides a brief overview of the project scrubber design relating to maintenance considerations. A discussion of the early results of the maintenance history is also provided. Repair techniques that have been developed and tested for ceramic tile lined modules are included. 1 fig.

Resolution measurement for scanning electron microscopes  

SciTech Connect

The resolution performance of a scanning electron microscope (SEM) is a primary specification of the instrument. For a high-resolution SEM (HRSEM) equipped with a field emission gun (FEG), image resolutions of less than 2 nm are commonly claimed. Generally, both manufacturers and customers identify image resolution as the single most important performance criterion. It is traditionally determined with specimens such as gold islands on bulk carbon supports, where the minimum apparent separation of two islands is claimed as the resolution. This procedure is highly subjective since the spacings are not known independently. Dodson and Joy (1990) have pointed out the paradox implicit in this approach - that ``the resolution of a given instrument can be verified only after a better instrument is available to characterize the structure spacing.`` By analogy to the now standard approach for high-resolution transmission electron microscopes (TEMs), Dodson and Joy (1990) investigated the use of Fourier Transforms (FT) of high-resolution SEM images for measuring resolution. Problems encountered by Dodson and Joy included obtaining a specimen with structural detail over the required range of spatial frequencies, and practical aspects of performing the FT processing. While we hope and expect that such FT techniques will be developed in the future, we have explored a different route to a less subjective resolution test that was also prompted by TEM experience, and which directly addresses the paradox posed by Dodson and Joy.

Fuel-constrained preventive maintenance scheduling for an electric power utility  

SciTech Connect

A close relationship exists between preventive maintenance scheduling for power generating units and fuel resource allocation. It is realized that unit maintenance scheduling and unit fuel allocation are both dynamic problems and depend upon one another. In this thesis, the two problems are considered together for the first time. Decomposition with the use of duality theory of nonlinear programming is used to solve the fuel-constrained maintenance scheduling problem; generalized Benders' decomposition is found to be a powerful optimization technique for this problem, and, together with its application, is discussed in detail. A model for solving the maintenance scheduling problem without fuel constraints is presented, and generalized Benders' decomposition is used to obtain the solution. A sample problem is presented, and some computational results are given. Two models are presented for the fuel-constrained problem. One model is based on generalized Benders' decomposition. A sample problem is presented to show the applicability of the solution technique; sensitivity analysis for different fuel limitations and different reliability tolerance levels is included with the results. The second model for the fuel-constrained problem uses a two-phased decomposition technique. The application of these two models is discussed.

A natural gas-fired combined-cycle power plant has operated successfully for the past three years at the 3800-acre Pitchess Honor Rancho jail complex in Saugus, Calif. One of the reasons for the plant's success has been its computerized maintenance system. This paper reports that utilization of the computerized plant maintenance system program, in conjunction with several data base programs, has increased the plant's reliability and trimmed costs. As we learned at Pitchess, a computerized maintenance program provides two key advantages over the traditional breakdown maintenance approach: minimal equipment breakdown, and a reduction in operations and maintenance man-hours.

Face super-resolution reconstruction from real low-resolution video sequences  

NASA Astrophysics Data System (ADS)

Extraction of high-resolution face image is crucial to detect suspect from low-resolution surveillance videos. Though previously published super-resolution image reconstruction techniques could produce a qualified high-resolution image from a set of simulated low-resolution images, but the reconstructed image from real low-resolution videos is always blurring. Two main reasons contribute for this: the process of image registration is ill-posed in nature and the sub-pixel information provided by the real video sequences is far less sufficient. In this paper, a joint image registration and face pattern-based high-resolution image reconstruction algorithm was proposed to tackle these two problems. Experimental results are also provided to demonstrate the effectiveness of the proposed algorithm.

Problem Solving  

NSDL National Science Digital Library

Problem solving is the thought processes involved in solving a problem. It is both a means of developing students' knowledge of mathematics and a critical outcome of a good mathematics education. A mathematical problem, as distinct from an exercise, requires the solver to search for a method for solving the problem rather than following a set procedure. Mathematical problem solving, therefore, requires an understanding of relevant concepts, procedures, and strategies. To become good problem solvers, students need many opportunities to formulate questions, model problem situations in a variety of ways, generalize mathematical relationships, and solve problems in both mathematical and everyday contexts.

The results of this assessment were evaluated to determine needed improvements in PNL Craft Services' current maintenance program. The objective of this implementation plan is to provide baseline information for compliance to the DOE 4330.4A, and for needed improvements. The prime consideration in applying a graded approach to the Order has been to maintain safe and reliable operations, environmental compliance, safeguards and security, programmatic mission, facility preservation, and/or other facility-specific requirements. Using the results of the self-assessment, PNL has selected nine of the 18 elements of the Maintenance Program defined by DOE Order 4330.4A for improvement. The elements selected for improvement are Training and Qualification of Maintenance Personnel; Maintenance Procedures; Planning, Scheduling, and Coordination of Maintenance; Control of Maintenance Activities; Post-Maintenance Testing; Facility Condition Inspection; Management Involvement; Maintenance History; and Additional Maintenance Requirements. Based upon graded approach and current funding, those elements considered most important have been selected as goals for earliest compliance. Commitment dates for these elements have been established for compliance. The remaining elements of noncompliance will be targeted for implementation during later budget periods.

The authors found similar attitudes toward methadone and methadone treatment programs in 75 detoxification and 115 methadone maintenance clients. Both groups expressed considerable ambivalence--although they viewed methadone as capable of helping them end their herioin addiction, they were concerned about possible methadone dependence and about side effects, both real and imagined. The authors stress the societal context of such concern and suggest that, althought they are not easily allayed, limiting the duration of methadone maintenace from the outset of treatment may be an ameliorative factor.

Insufficient maintenance DNA methylation is associated with abnormal embryonic development  

PubMed Central

Background Early pregnancy loss (EPL) is a frustrating clinical problem, whose mechanisms are not completely understood. DNA methylation, which includes maintenance methylation and de novo methylation directed by DNA methyltransferases (DNMTs), is important for embryo development. Abnormal function of these DNMTs may have serious consequences for embryonic development. Methods To evaluate the possible involvement of DNA methylation in human EPL, the expression of DNMT proteins and global methylation of DNA were assessed in villous or decidua from EPL patients. The association of maintenance methylation with embryo implantation and development was also examined. Results We found that DNMT1 and DNMT3A were both expressed in normal human villous and decidua. DNMT1 expression and DNA global methylation levels were significantly down-regulated in villous of EPL. DNMT3A expression was not significantly changed in the EPL group compared to controls in either villous or decidua. We also found that disturbance of maintenance methylation with a DNMT1 inhibitor may result in a decreased global DNA methylation level and impaired embryonic development in the mouse model, and inhibit in vitro embryo attachment to endometrial cells. Conclusions Our results demonstrate that defects in DNA maintenance methylation in the embryo, not in the mother, are associated with abnormal embryonic implantation and development. The findings of the current study provide new insights into the etiology of EPL.

No maintenance -- no energy efficiency  

SciTech Connect

Field investigations illustrate that it is not realistic to expect new high-tech equipment to function for a full life expectancy at high efficiency without significant operations and maintenance (O&M). A simple walk through inspection of most buildings reveals extensive equipment that is being operated on manual override, is incorrectly adjusted and operating inefficiently, or is simply inoperative. This point is illustrated with two examples at Robins Air Force Base, Georgia. The first describes development of a comprehensive, base-wide, steam trap maintenance program. The second describes a measured evaluation from a typical office building. The objective of both examples was to assess the importance of proper O&M. The proposed ``O&M First`` philosophy will result in more efficient building HVAC operation, provide improved services to the building occupants, and reduce energy consumption and unscheduled equipment repair/replacement. Implementation of a comprehensive O&M program will result in a 15--25% energy savings. The O&M foundation that is established will allow other energy conservation activities such is demand side management or energy management and control systems, to achieve and maintain their expected energy savings.

SciTech Connect

This Maintenance Improvement Plan has been developed for maintenance functions associated with the 222-S Laboratory. This plan is developed from the guidelines presented by Department of Energy (DOE) Order 4330.4B, Maintenance Management Program (DOE 1994), Chapter 11. The objective of this plan is to provide information for establishing and identifying WMH conformance programs and policies applicable to implementation of DOE Order 4330.4B guidelines. In addition, this maintenance plan identifies the actions necessary to develop a cost effective and efficient maintenance program at 222-S Laboratory. Maintenance activities are mainly going to be performed by existing maintenance organizations within Waste Management Federal Services of Hanford (WMH). Most maintenance performed at 222-S Laboratory is performed by the 222-S Laboratory maintenance organization. This 222-S Laboratory Maintenance Implementation Plan provides the interface requirements and responsibilities as they apply specifically to 222-S Laboratory. This document provides an implementation schedule which has been developed for items considered to be deficient or in need of improvement. The discussion section as applied to 222-S Laboratory implementation has been developed from a review of programs and practices utilizing the graded approach. Biennial review and additional reviews are conducted as significant programmatic and mission changes are made. This document is revised as necessary to keep this document current and in compliance with DOE requirements.

Reliability centered maintenance in astronomical infrastructure facilities  

NASA Astrophysics Data System (ADS)

Hundreds of mirror segment, thousands of high precision actuators, highly complex mechanical, hydraulic, electrical and other technology subsystems, and highly sophisticated control systems: an ELT system consists of millions of individual parts and components, each of them may fail and lead to a partial or complete system breakdown. The traditional maintenance concepts characterized by predefined preventive maintenance activities and rigid schedules are not suitable for handling this large number of potential failures and malfunctions and the extreme maintenance workload. New maintenance strategies have to be found suitable to increase reliability while reducing the cost of needless maintenance services. The Reliability Centred Maintenance (RCM) methodology is already used extensively by airlines, and in industrial and marine facilities and even by scientific institutions like NASA. Its application increases the operational reliability while reducing the cost of unnecessary maintenance activities and is certainly also a solution for current and future ELT facilities. RCM is a concept of developing a maintenance scheme based on the reliability of the various components of a system by using "feedback loops between instrument / system performance monitoring and preventive/corrective maintenance cycles." Ideally RCM has to be designed within a system and should be located in the requirement definition, the preliminary and final design phases of new equipment and complicated systems. However, under certain conditions, an implementation of RCM into the maintenance management strategy of already existing astronomical infrastructure facilities is also possible. This presentation outlines the principles of the RCM methodology, explains the advantages, and highlights necessary changes in the observatory development, operation and maintenance philosophies. Presently, it is the right time to implement RCM into current and future ELT projects and to save up to 50% maintenance and operation costs.

Most chiropractors advise patients to have regular maintenance treatments with spinal manipulation, even in the absence of any symptoms or diseases. This article evaluates the evidence for or against this approach. No compelling evidence was found to indicate that chiropractic maintenance therapy effectively prevents symptoms or diseases. As spinal manipulation has repeatedly been associated with considerable harm, the risk benefit balance of chiropractic maintenance care is not demonstrably positive. Therefore there are no good reasons to recommend it. PMID:19465044

Maintenance of dietary behavior change.  

PubMed

Reducing dietary fat, saturated fat, and sodium and increasing intakes of dietary fiber and fruits and vegetables are important for cardiopulmonary risk reduction. Behaviorally, these dietary changes are very challenging, and in different ways. Fewer than half of U.S. adults have diets meeting recommended intakes of these constituents, and many do not see a need to align their diets with recommendations. Various nutrition education and behavioral counseling approaches have been shown to facilitate changes in fat, fiber, sodium, and fruits and vegetables, but primarily in research settings and among the highly motivated. Practice-based and interdisciplinary studies are needed to refine strategies to effect long-term dietary changes, to differentiate behavioral issues for changes involving additions versus deletions from the diet, and to elucidate the roles of sensory, psychosocial, and contextual factors in adoption and maintenance.

Maintenance management at La Silla Paranal Observatory  

NASA Astrophysics Data System (ADS)

From the beginning of the VLT project, the European Southern Observatory (ESO) considered the application of a competent maintenance strategy a fundamental aspect for future operations of the Paranal Observatory. For that purpose, a special maintenance philosophy was developed during the project stage and applied during the initial years of operations. The merging of the La Silla and Paranal Observatories in 2005 added a new managerial challenge to the regular operational requirements (high availability and reliability) which motivated ESO Management to develop a stronger strategy for the operations of the new merged Observatory. Part of the new strategy considered the creation of a dedicated department for the management of all maintenance activities, separating this support from the traditional scheme where the Engineering Department had the responsibility for the entire technical support to operations. In order to keep a competent level of maintenance operations for the new unified Observatory, the La Silla Paranal (LSP) Maintenance Department has been using a well known maintenance management model used in various industrial applications as a guide. Today the operations of the Maintenance Department are concentrated on developing and implementing practices regarding concepts such as Maintenance Tactics, Planning, Data Management, Performance Indicators and Material Management. In addition to that, advances related to Reliability Analysis been taken in order to reach a superior level of excellence. The results achieved by the LSP Maintenance Department are reflected in a reduced rate of functional failures, allowing uninterrupted operations of the Observation sites.

Reliability centered maintenance streamlining through lessons learned  

SciTech Connect

In late 1986, PSE and G concluded that the Nuclear Department would develop a consistent approach to maintenance at Artificial Island (Salem and Hope Creak nuclear units). Preventive maintenance (PM) would be the heart of this approach. In the last six months of 1987 departments affected by the maintenance program participated on working groups that developed the Artificial Island maintenance philosophy. The central theme of the maintenance philosophy is the RCM (reliability centered maintenance) process. A pilot project tested the process in 1988. In 1989 the Central PM Group formed and in 1990 was given responsibility and authority to analyze, approve, implement, and control PM program changes. RCM is the central theme of the PM improvement effort but not the whole effort. Other important pieces included in this paper are: development of a common PM program, improvement of work instructions, development of predictive maintenance techniques into programs, development of a PM basis database, development of PM feedback from failure trends, root cause analysis, maintenance performance indicators, technicians, and engineers.

A glue for heterochromatin maintenance  

PubMed Central

Trimethylation of histone H3 lysine 9 and the subsequent binding of heterochromatin protein 1 (HP1) mediate the formation and maintenance of pericentromeric heterochromatin. Trimethylation of H3K9 is governed by the histone methyltransferase SUV39H1. Recent studies of HP1 dynamics revealed that HP1 is not a stable component of heterochromatin but is highly mobile (Cheutin, T., A.J. McNairn, T. Jenuwein, D.M. Gilbert, P.B. Singh, and T. Misteli. 2003. Science. 299:721–725; Festenstein, R., S.N. Pagakis, K. Hiragami, D. Lyon, A. Verreault, B. Sekkali, and D. Kioussis. 2003. Science. 299:719–721). Because the mechanism by which SUV39H1 is recruited to and interacts with heterochromatin is unknown, we studied the dynamic properties of SUV39H1 in living cells by using fluorescence recovery after photobleaching and fluorescence resonance energy transfer. Our results show that a substantial population of SUV39H1 is immobile at pericentromeric heterochromatin, suggesting that, in addition to its catalytic activity, SUV39H1 may also play a structural role at pericentromeric regions. Analysis of SUV39H1 deletion mutants indicated that the SET domain mediates this stable binding. Furthermore, our data suggest that the recruitment of SUV39H1 to heterochromatin is at least partly independent from that of HP1 and that HP1 transiently interacts with SUV39H1 at heterochromatin.

Problem Stabilization  

PubMed Central

Background Public health nurse (PHN) home visiting programs have been widely employed to improve life course trajectories for high risk mothers. Home visiting programs are often lengthy, during which PHNs simultaneously address multiple problems using diverse interventions over several client encounters. To manage PHN caseloads it is critical to understand the trajectory of client improvement and the optimal duration or services. PHN documentation data enable intervention trajectory research for specific client problems. A new metric called problem stabilization is proposed for evaluating interim improvement during PHN home visiting. Problem stabilization is an intervention pattern for a client problem that is characterized by co-occurring actions (i.e. teaching, guidance, and counseling; treatments and procedures; case management; and/or surveillance) during a client encounter; followed by surveillance actions only for that problem during a subsequent client encounter. The purpose of the study was to investigate problem stabilization during home visiting services for high risk mothers. Methods A retrospective cohort was created using family home visiting intervention documentation data from a local Midwest public health agency over a six year period (2000–2005). The data set consisted of Omaha System interventions for 720 high risk mothers. Analysis was conducted using descriptive statistics and Kaplan Meier curves. Results On average 30.1% of the time, client problems stabilized before discharge. Stabilization patterns differed by problem. Time to stabilization was longest for Caretaking/parenting and Antepartum/postpartum problems, and shortest for Residence and Mental health problems. Conclusions Problem stabilization, a proposed intermediate outcome of PHN home visiting care, appears to be meaningful in describing client response to PHN intervention. This metric is an example of meaningful use of structured clinical electronic health record data for program evaluation and clinical decision support.

CleanFleet. Final report: Volume 3, vehicle maintenance and durability  

SciTech Connect

CleanFleet is a demonstration of panel vans operating on five alternative motorfuels in commercial package delivery operations in the South Coast Air Basin of California. The five alternative fuels are propane gas, compressed natural gas (CNG), California Phase 2 reformulated gasoline (RFG), methanol (M-85 with 15 percent RFG), and electricity. Data were gathered on in-use emissions, operations, and fleet economics. This volume of the final report summarizes the maintenance required on these vans from the time they were introduced into the demonstration (April through early November 1992) until the end of the demonstration in September 1994. The vans were used successfully in FedEx operations; but, to varying degrees, the alternative fuel vehicles required more maintenance than the unleaded gasoline control vehicles. The maintenance required was generally associated with the development state of the fuel-related systems. During the demonstration, no non-preventive maintenance was required on the highly developed fuel-related systems in any of the unleaded gasoline production vehicles used either as controls or as RFG test vehicles. The maintenance problems encountered with the less developed systems used in this demonstration may persist in the short term with vehicles featuring the same or similar systems. This means that fleet operators planning near-term acquisitions of vehicles incorporating such systems should consider the potential for similar problems when (1) selecting vendors and warranty provisions and (2) planning maintenance programs.

Building a maintenance policy through a multi-criterion decision-making model  

NASA Astrophysics Data System (ADS)

A major competitive advantage of production and service systems is establishing a proper maintenance policy. Therefore, maintenance managers should make maintenance decisions that best fit their systems. Multi-criterion decision-making methods can take into account a number of aspects associated with the competitiveness factors of a system. This paper presents a multi-criterion decision-aided maintenance model with three criteria that have more influence on decision making: reliability, maintenance cost, and maintenance downtime. The Bayesian approach has been applied to confront maintenance failure data shortage. Therefore, the model seeks to make the best compromise between these three criteria and establish replacement intervals using Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE II), integrating the Bayesian approach with regard to the preference of the decision maker to the problem. Finally, using a numerical application, the model has been illustrated, and for a visual realization and an illustrative sensitivity analysis, PROMETHEE GAIA (the visual interactive module) has been used. Use of PROMETHEE II and PROMETHEE GAIA has been made with Decision Lab software. A sensitivity analysis has been made to verify the robustness of certain parameters of the model.

Design of a decision support system for preventive maintenance planning in health structures.  

PubMed

The appropriate maintenance of medical devices, including performance inspections and preventive maintenance, is fundamental in mitigating clinical risk caused by adverse events in health care. Although several models for managing and planning preventive maintenance have been developed, the problem is lacking in standard methodology and still presents an open challenge for today's health experts. This paper aims to provide and develop methodology together with support systems able to assist decision makers in constructing preventive maintenance and performance inspection plans, taking into account both the technical and economic needs of hospital clinical engineering departments. Interventions by decision makers are of crucial importance within complex situations where large numbers, types of devices and different contractual situations are involved. SISMA system has achieved optimal results with minimum expense and maximum security for patients and technicians at the University Hospital of Florence where it has been applied in actual case studies.

Democratic Censure Resolution: CNN  

NSDL National Science Digital Library

On December 9, the US House of Representatives Judiciary Committee Republicans released a draft resolution containing four articles of impeachment. The Committee Democrats responded with a proposed censure resolution as an alternative to impeachment. The articles will now be debated by Committee members, amended, and voted on individually. Most analysts agree that at least one article will be sent to the full House. A majority vote there would send it to the Senate for trial, where a two-thirds majority is necessary for impeachment. The text of the Democratic censure resolution is available from both the Washington Post and CNN Websites, which also offer analysis and commentary.

Inverse problems in astronomical adaptive optics  

Microsoft Academic Search

Adaptive optics (AO) is a technology used in ground-based astronomy to correct for the wavefront aberrations and loss of image quality caused by atmospheric turbulence. Provided some difficult technical problems can be overcome, AO will enable future astronomers to achieve nearly diffraction-limited performance with the extremely large telescopes that are currently under development, thereby greatly improving spatial resolution, spectral resolution

Improving Inconsistency Resolution with Side-Effect Evaluation and Costs  

Microsoft Academic Search

Consistency management is a major requirement in software engineering. Although this problem has attracted significant attention\\u000a in the literature, support for inconsistency resolution is still not standard for modeling tools. In this paper, we introduce\\u000a explicit side-effect expressions for each inconsistency resolution and costs for each inconsistency type. This allows a fine-grained\\u000a evaluation of each possible inconsistency resolution for a
