Energy-Performance-Based Design-Build Process: Strategies for Procuring High-Performance Buildings on Typical Construction Budgets: Preprint  

SciTech Connect

NREL experienced a significant increase in employees and facilities on our 327-acre main campus in Golden, Colorado over the past five years. To support this growth, researchers developed and demonstrated a new building acquisition method that successfully integrates energy efficiency requirements into the design-build requests for proposals and contracts. We piloted this energy performance based design-build process with our first new construction project in 2008. We have since replicated and evolved the process for large office buildings, a smart grid research laboratory, a supercomputer, a parking structure, and a cafeteria. Each project incorporated aggressive efficiency strategies using contractual energy use requirements in the design-build contracts, all on typical construction budgets. We have found that when energy efficiency is a core project requirement as defined at the beginning of a project, innovative design-build teams can integrate the most cost effective and high performance efficiency strategies on typical construction budgets. When the design-build contract includes measurable energy requirements and is set up to incentivize design-build teams to focus on achieving high performance in actual operations, owners can now expect their facilities to perform. As NREL completed the new construction in 2013, we have documented our best practices in training materials and a how-to guide so that other owners and owner's representatives can replicate our successes and learn from our experiences in attaining market viable, world-class energy performance in the built environment.

NASA procurement report, FY 1993  

NASA Technical Reports Server (NTRS)

Summary data on all NASA procurement actions and detailed information on contracts, grants, agreements, and other procurements over $25,000 awarded by NASA during fiscal year 1993. The dollar value on procurements over $25,000 amounted to 97 percent of the total dollar value of procurement actions completed during fiscal year 1993. However, these larger procurements accounted for only 29 percent of the total actions. Procurement action, as used in this report, means contractural actions to obtain supplies, services, or construction which increase or decrease funds. A procurement action thus may be a new procurement, or modifications such as supplemental agreements, change orders, or terminations to an existing contract that change the total amount of funds obligated. An obligation is a contractual commitment to pay for supplies or services that are specified in the contract.

Using an Energy Performance Based Design-Build Process to Procure a Large Scale Low-Energy Building: Preprint  

SciTech Connect

This paper will review a procurement, acquisition, and contract process of a large-scale replicable net zero energy (ZEB) office building. The owners developed and implemented an energy performance based design-build process to procure a 220,000 ft2 office building with contractual requirements to meet demand side energy and LEED goals. We will outline the key procurement steps needed to ensure achievement of our energy efficiency and ZEB goals. The development of a clear and comprehensive Request for Proposals (RFP) that includes specific and measurable energy use intensity goals is critical to ensure energy goals are met in a cost effective manner. The RFP includes a contractual requirement to meet an absolute demand side energy use requirement of 25 kBtu/ft2, with specific calculation methods on what loads are included, how to normalize the energy goal based on increased space efficiency and data center allocation, specific plug loads and schedules, and calculation details on how to account for energy used from the campus hot and chilled water supply. Additional advantages of integrating energy requirements into this procurement process include leveraging the voluntary incentive program, which is a financial incentive based on how well the owner feels the design-build team is meeting the RFP goals.

A lunar construction shack vehicle: Final design  

NASA Technical Reports Server (NTRS)

A lunar construction shack vehicle is a critical component in most of the plans proposed for the construction of a permanent base on the moon. The Selene Engineering Company (SEC) has developed a concept for this vehicle which is both innovative and practical. The design makes use of the most advanced technology available to meet the goals for a safe, versatile and durable habitat that will serve as a starting point for the initial phase of the construction of a permanent lunar base. This document outlines SEC's proposed design for a lander vehicle which will be fully self-sufficient and will provide for all necessary life support, including consumables and radiation protection, needed by the construction crew until they can complete the assembly of a more permanent habitat. Since it is highly likely that it will take more than one crew to complete the construction of a permanent lunar base, the design emphasis is on systems which can be easily maintained and resupplied and which will take a minimum of start up preparation by succeeding crews.

Design and Construction of Cryogenic Optomechanical System  

NASA Astrophysics Data System (ADS)

One key challenge to observing quantum phenomena in a macroscopic mechanical oscillator is reaching its ground state. To achieve the low temperatures required for this, we utilize resolved sideband laser cooling of a few hundred kHz mechanical oscillator with high mechanical Q (a Si3N4 membrane) inside a high finesse optical cavity, in addition to cryogenically reducing the bath temperature. Realizing high Q and high finesse cavity optomechanical devices in a cryogenic environment requires overcoming a number of challenges. In this talk, we describe the design and construction of such a device working at a bath temperature of 300 mK (in a 3He refrigerator) and suited for operation at lower temperatures (in a dilution refrigerator). The design incorporates in-situ commercial piezo actuators (manufactured by Janssen Precision Engineering) to couple externally prepared laser light into the cold optical cavity. The design also incorporates filtering cavities to suppress classical laser noise, and acoustic and seismic isolation of the experiment.

An inexpensive, charge-balanced rodent deep brain stimulation device: a step-by-step guide to its procurement and construction  

PubMed Central

Background Despite there being a relatively large number of methods papers which detail specifically the development of stimulation devices, only a small number of reports involve the application of these devices in freely moving animals. To date multiple preclinical neural stimulators have been designed and described but have failed to make an impact on the methods employed by the majority of laboratories studying DBS. Thus, the overwhelming majority of DBS studies are still performed by tethering the subject to an external stimulator. We believe that the low adoption rate of previously described methods is a result of the complexity of replicating and implementing these methods. New Method Here were describe both the design and procurement of a simple and inexpensive stimulator designed to be compatible with commonly used, commercially available electrodes (Plastics 1). Results This system is initially programmable in frequency, pulsewidth and current amplitude, and delivers biphasic, charge-balanced output to two independent electrodes.

Design and construction of the BESIII detector  

NASA Astrophysics Data System (ADS)

This paper will discuss the design and construction of BESIII, which is designed to study physics in the ?-charm energy region utilizing the new high luminosity BEPCII double ring e +e - collider. The expected performance will be given based on Monte Carlo simulations and results of cosmic ray and beam tests. In BESIII, tracking and momentum measurements for charged particles are made by a cylindrical multilayer drift chamber in a 1 T superconducting solenoid. Charged particles are identified with a time-of-flight system based on plastic scintillators in conjunction with dE/dx (energy loss per unit pathlength) measurements in the drift chamber. Energies of electromagnetic showers are measured by a CsI(Tl) crystal calorimeter located inside the solenoid magnet. Muons are identified by arrays of resistive plate chambers in a steel magnetic yoke for the flux return. The level 1 trigger system, data acquisition system and the detector control system based on networked computers will also be described.

ATST Enclosure final design and construction plans  

NASA Astrophysics Data System (ADS)

The Advanced Technology Solar Telescope (ATST) is a 4-m class solar telescope to be built at the Haleakal' High Altitude Observatory Site in Maui, Hawai'i. It will be the largest solar telescope in the world, with unprecedented abilities to view details of the Sun. Using adaptive optics technology, ATST will be able to provide the sharpest views ever taken of the solar surface. It is expected that the 4-meter class telescope will have a significant impact on the study of stellar magnetic fields, plasma physics and astronomy, allowing scientists to learn even more about the Sun and solarterrestrial interactions. The ATST enclosure is unique in its functionality, as not only it provides protection from adverse weather conditions when not in operation, but it also positions the telescope Aperture Stop which must be accurately aligned so that the primary mirror is fully illuminated, while insolation in other telescope equipment is prevented. The proposed design is based on a multi-sector shutter system arrangement with an innovative crawler drive system (patent pending) assembled on two steel fabricated arch girders. These arch girders are stiffened by a secondary structure and supported on a steel fabricated base ring. The base ring rests on an azimuth mechanism composed of several driven/idling bogies. The outer shape of the enclosure is configured by the secondary structure which supports the cladding and has been selected so as to minimize the solar irradiated surface and reduce shell seeing in early morning hours when the seeing is the best. This paper describes the work performed by AEC IDOM and ATST team to define both the final design of the Enclosure and the construction plan to erect it at the Observatory Site.

ORNL engineering design and construction reengineering report  

SciTech Connect

A team composed of individuals representing research and development (R and D) divisions, infrastructure support organizations, and Department of Energy (DOE)-Oak Ridge Operations was chartered to reengineer the engineering, design, and construction (ED and C) process at Oak Ridge National Laboratory (ORNL). The team recognized that ED and C needs of both R and D customers and the ORNL infrastructure program have to be met to maintain a viable and competitive national laboratory. Their goal was to identify and recommend implementable best-in-class ED and C processes that will efficiently and cost-effectively support the ORNL R and D staff by being responsive to their programmatic and infrastructure needs. The team conducted process mapping of current and potential ED and C approaches, developed idealized versions of ED and C processes, and identified potential barriers to an efficient ED and C process. Eight subteams were assigned to gather information and to evaluate the significance of potential barriers through benchmarking, surveys, interviews, and reviews of key topical areas in order to determine whether the perceived barriers were real and important and whether they resulted from laws or regulations over which ORNL has no control.

INTERIOR DUCT SYSTEM DESIGN, CONSTRUCTION, AND PERFORMANCE  

SciTech Connect

By removing air distribution and conditioning equipment from unconditioned spaces, homeowners stand to benefit substantially with respect to both energy savings and indoor air quality. Duct leakage introduces: Greater heating and cooling loads from air at extreme temperatures and humidity levels; Outside air and air from unconditioned spaces that may contain air borne contaminants, combustion gases, pollen, mold spores, and/or particles of building materials; and Higher whole-house infiltration/exfiltration rates. Exemplary studies conducted since 1990 have demonstrated the prevalence of duct leakage throughout the United States and measured energy savings of approximately 20% during both heating and cooling seasons from leakage reduction. These all dealt with duct leakage to and/or from unconditioned spaces. In the building science community, leakage within the conditioned space is generally presumed to eliminate the negative consequences of duct leakage with the exception of possibly creating pressure imbalances in the house which relates to higher infiltration and/or exfiltration. The practical challenges of isolating ducts and air handlers from unconditioned spaces require builders to construct an air-tight environment for the ducts. Florida Solar Energy Center researchers worked with four builders in Texas, North Carolina, and Florida who build a furred-down chase located either in a central hallway or at the edges of rooms as an architectural detail. Some comparison homes with duct systems in attics and crawl spaces were included in the test group of more than 20 homes. Test data reveals that all of the duct/AHU systems built inside the conditioned space had lower duct leakage to unconditioned spaces than their conventional counterparts; however, none of the homes was completely free of duct leakage to unconditioned spaces. Common problems included wiring and plumbing penetrations of the chase, failure to treat the chase as an air tight space, and misguided fresh air inlet design. Improvements were implemented by the Texas builder and retested in July. Results showed a 36% reduction in duct leakage, significant enough to warrant the builder adopting the new sealing procedure.

Rationale and design of a study using a standardized locally procured macronutrient supplement as adjunctive therapy to HIV treatment in Kenya.  

PubMed

Poor nutritional status at initiation of antiretroviral therapy (ART) is predictive of mortality. Decreased dietary intake is a major determinant of weight loss in HIV. Despite a biological rationale to treat undernutrition in adults receiving ART, few studies have provided data on feasibility, safety, effectiveness, and sustainability of specific macronutrient supplements with HIV treatment in adults, especially supplements such as a food basket, a supplement approach seldom evaluated in spite of its wide use. We present the rationale and design for a study of a locally procured macronutrient supplement given to HIV-infected patients initiating ART with a body mass index (BMI) ?20.0 kg/m(2). The objective was to determine feasibility of procurement, distribution, safety and to obtain preliminary effectiveness data for a locally procured supplement. The design was a comparative study for 200 adult participants at two Kenya government-supported clinics. The primary outcome was BMI at 24 weeks. Supplement duration was 24 weeks, total follow-up was 48 weeks, and the study included a comparison site. Novel aspects of this study include use of a standardized macronutrient supplement to protect the participant against household food sharing, and a complementary micronutrient supplement. Comprehensive data collected included dietary intake, HIV-related quality-of-life, food security, neuropsychiatric assessments, laboratory studies, and household geomapping. Assessments were made at baseline, at 24 weeks, and at 48 weeks post-ART initiation. Challenges included establishing a partnership with local millers, distribution from the HIV clinic, food safety, and tracking of participants. These findings will help inform nutrition support programming in Kenya and similar settings, and provide needed data regarding use of macronutrient supplements as an adjunctive intervention with ART.

This article describes the design and benefits of a Science and Technology Center (STC)- based workshop sponsored by the National Science Foundation (NSF). The topic in this case was hydrologic literacy in teaching issues and concepts concerning semi-arid hydrology in the Southwest, as defined by educators and scientists associated with Sustainability of semi-Arid Hydrology and Riparian Areas (SAHRA). Participants concluded that a science workshop designed to explicitly combine science content and inquiry-based pedagogy is beneficial, but learning new content is not a guarantee that it will be used in the participants' science curricula. To increase chances for teachers to alter practice, workshops must model new pedagogy while teaching new content, and instructors must be very explicit about how new teaching techniques were used to teach new content.

Strategies for Designing Transgenic DNA Constructs  

PubMed Central

Generation and characterization of transgenic mice are important elements of biomedical research. In recent years, transgenic technology has become more versatile and sophisticated, mainly because of the incorporation of recombinase-mediated conditional expression and targeted insertion, site-specific endonuclease-mediated genome editing, siRNA-mediated gene knockdown, various inducible gene expression systems, and fluorescent protein marking and tracking techniques. Site-specific recombinases (such as PhiC31) and engineered endonucleases (such as ZFN and Talen) have significantly enhanced our ability to target transgenes into specific genomic loci, but currently a great majority of transgenic mouse lines are continuingly being created using the conventional random insertion method. A major challenge for using this conventional method is that the genomic environment at the integration site has a substantial influence on the expression of the transgene. Although our understanding of such chromosomal position effects and our means to combat them are still primitive, adhering to some general guidelines can significantly increase the odds of successful transgene expression. This chapter first discusses the major problems associated with transgene expression, and then describes some of the principles for using plasmid and bacterial artificial chromosomes (BACs) for generating transgenic constructs. Finally, the strategies for conducting each of the major types of transgenic research are discussed, including gene overexpression, promoter characterization, cell-lineage tracing, mutant complementation, expression of double or multiple transgenes, siRNA knockdown, and conditional and inducible systems.

Laboratory Design, Construction, and Renovation: Participants, Process, and Product  

NSDL National Science Digital Library

Laboratory facilities are complex, technically sophisticated, and mechanically intensive structures that are expensive to build and to maintain. Hundreds of decisions must be made before and during new construction or renovation that will determine how successfully the facility will function when completed and how successfully it can be maintained once put into service. This book provides guidance on effective approaches for building laboratory facilities in the chemical and biochemical sciences. It contains both basic and laboratory-specific information addressed to the user community-the scientists and administrators who contract with design and construction experts. The book will also be important to the design and construction communities-the architects, laboratory designers, and engineers who will design the facility and the construction personnel who will build it-to help them communicate with the scientific community for whom they build laboratory facilities.

Design and construction considerations for a lunar outpost  

NASA Astrophysics Data System (ADS)

The applicability of the existing design codes to the fabrication and erection of structures on the moon is discussed. It is shown, in particular, that the specifications of such codes as those of the American Institute for Steel Construction and the American Concrete Institute will not be applicable to lunar construction. While some earth construction experience will be useful, construction in a low-g microdust vacuum requires almost completely new procedures. The development of a steel-frame-based lunar outpost is considered as an example.

The constructal law and the evolution of design in nature  

NASA Astrophysics Data System (ADS)

The constructal law accounts for the universal phenomenon of generation and evolution of design (configuration, shape, structure, pattern, rhythm). This phenomenon is observed across the board, in animate, inanimate and human systems. The constructal law states the time direction of the evolutionary design phenomenon. It defines the concept of design evolution in physics. Along with the first and second law, the constructal law elevates thermodynamics to a science of systems with configuration. In this article we review the more recent work of our group, with emphasis on the advances made with the constructal law in the natural sciences. Highlighted are the oneness of animate and inanimate designs, the origin of finite-size organs on animals and vehicles, the flow of stresses as the generator of design in solid structures (skeletons, vegetation), the universality and rigidity of hierarchy in all flow systems, and the global design of human flows. Noteworthy is the tapestry of distributed energy systems, which balances nodes of production with networks of distribution on the landscape, and serves as key to energy sustainability and empowerment. At the global level, the constructal law accounts for the geography and design of human movement, wealth and communications.

CHARIS Construction Status, Design, and Future Science  

NASA Astrophysics Data System (ADS)

Princeton University is funded by the National Astronomical Observatory of Japan to build an integral field spectrograph (IFS) dubbed the Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS). CHARIS is part of the ongoing exoplanet science effort at the Subaru Telescope, and will serve as the science imager for the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) and AO188 systems. The principal science goals are disk imaging and high contrast spectra of brown dwarfs and hot Jovian planets across J, H, and K bands. SCExAO is a coronagraphic and wavefront control system that will be capable of extreme adaptive optics and quasi-static speckle suppression. Speckle suppression is meant to reduce the residual speckle to a level that makes it possible to detect planets at very low inner working angles (~80 mas). Even so, CHARIS must mitigate spectral contamination from the residual speckle halo due to crosstalk between the closely packed spectra of the image. CHARIS mitigates crosstalk via an array of field stops behind the lenslet array and carefully toleranced relay optics. This reduces uncertainty in the measured spectrum of the exoplanets by increasing robustness of the spectrograph to nearby bright speckles. Mitigating crosstalk in hardware both improves science and reduces computational overhead. Combined with a detailed wavefront budget this improves the utility of CHARIS in the speckle control loop. Another defining feature of CHARIS is its disperser design. In addition to imaging in individual J, H, and K bands, CHARIS has a fourth mode that images across all three simultaneously. This required an improvement in the linearity of dispersion from 1.15 to 2.38 microns. To do so the CHARIS project has chosen a new high-index dispersing material and characterized its properties at cryogenic temperatures. We present the build status of the spectrograph, including status and viability of operating an H2RG detector directly using a SAM card via gigabit Ethernet over Linux. In addition to the stated and as-built specifications of the instrument hardware, we discuss the future of science impacts of CHARIS at the Subaru telescope.

The constructal law of design and evolution in nature  

PubMed Central

Constructal theory is the view that (i) the generation of images of design (pattern, rhythm) in nature is a phenomenon of physics and (ii) this phenomenon is covered by a principle (the constructal law): ‘for a finite-size flow system to persist in time (to live) it must evolve such that it provides greater and greater access to the currents that flow through it’. This law is about the necessity of design to occur, and about the time direction of the phenomenon: the tape of the design evolution ‘movie’ runs such that existing configurations are replaced by globally easier flowing configurations. The constructal law has two useful sides: the prediction of natural phenomena and the strategic engineering of novel architectures, based on the constructal law, i.e. not by mimicking nature. We show that the emergence of scaling laws in inanimate (geophysical) flow systems is the same phenomenon as the emergence of allometric laws in animate (biological) flow systems. Examples are lung design, animal locomotion, vegetation, river basins, turbulent flow structure, self-lubrication and natural multi-scale porous media. This article outlines the place of the constructal law as a self-standing law in physics, which covers all the ad hoc (and contradictory) statements of optimality such as minimum entropy generation, maximum entropy generation, minimum flow resistance, maximum flow resistance, minimum time, minimum weight, uniform maximum stresses and characteristic organ sizes. Nature is configured to flow and move as a conglomerate of ‘engine and brake’ designs. PMID:20368252

Design maps for scaffold constructs in bone regeneration.  

PubMed

In this article, we propose a methodology for the rational design of scaffold constructs in bone-tissue engineering. The construct under investigation is a sandwich structure with an Intramedullary rod (IM), a Biological Sponge (BS) and an External sleeve (ES). The IM rod provides axial resistance, BS facilitates the growth of new bone and ES provides stability to the construct by resisting torsion and bending. We demonstrate that only select combinations of stiffness between IM and ES facilitate the growth of new bone. Perren's interfragmentary strain theory is employed to clearly identify regions favoring bone growth from those favoring the formation of cartilage. Finally, design maps are constructed that clearly identify the combinations facilitating timely bone growth. PMID:23839166

The Advanced Technology Solar Telescope: design and early construction  

NASA Astrophysics Data System (ADS)

The National Solar Observatory’s (NSO) Advanced Technology Solar Telescope (ATST) is the first large U.S. solar telescope accessible to the worldwide solar physics community to be constructed in more than 30 years. The 4-meter diameter facility will operate over a broad wavelength range (0.35 to 28 ?m ), employing adaptive optics systems to achieve diffraction limited imaging and resolve features approximately 20 km on the Sun; the key observational parameters (collecting area, spatial resolution, spectral coverage, polarization accuracy, low scattered light) enable resolution of the theoretically-predicted, fine-scale magnetic features and their dynamics which modulate the radiative output of the sun and drive the release of magnetic energy from the Sun’s atmosphere in the form of flares and coronal mass ejections. In 2010, the ATST received a significant fraction of its funding for construction. In the subsequent two years, the project has hired staff and opened an office on Maui. A number of large industrial contracts have been placed throughout the world to complete the detailed designs and begin constructing the major telescope subsystems. These contracts have included the site development, AandE designs, mirrors, polishing, optic support assemblies, telescope mount and coudé rotator structures, enclosure, thermal and mechanical systems, and high-level software and controls. In addition, design development work on the instrument suite has undergone significant progress; this has included the completion of preliminary design reviews (PDR) for all five facility instruments. Permitting required for physically starting construction on the mountaintop of Haleakal?, Maui has also progressed. This paper will review the ATST goals and specifications, describe each of the major subsystems under construction, and review the contracts and lessons learned during the contracting and early construction phases. Schedules for site construction, key factory testing of major subsystems, and integration, test and commissioning activities will also be discussed.

Transitioning from conceptual design to construction performance specification  

NASA Astrophysics Data System (ADS)

On successful completion of a conceptual design review by a funding agency or customer, there is a transition phase before construction contracts can be placed. The nature of this transition phase depends on the Project's approach to construction and the particular subsystem being considered. There are generically two approaches; project retention of design authority and issuance of build to print contracts, or issuance of subsystem performance specifications with controlled interfaces. This paper relates to the latter where a proof of concept (conceptual or reference design) is translated into performance based sub-system specifications for competitive tender. This translation is not a straightforward process and there are a number of different issues to consider in the process. This paper deals with primarily the Telescope mount and Enclosure subsystems. The main subjects considered in this paper are: • Typical status of design at Conceptual Design Review compared with the desired status of Specifications and Interface Control Documents at Request for Quotation. • Options for capture and tracking of system requirements flow down from science / operating requirements and sub-system requirements, and functional requirements derived from reference design. • Requirements that may come specifically from the contracting approach. • Methods for effective use of reference design work without compromising a performance based specification. • Management of project team's expectation relating to design. • Effects on cost estimates from reference design to actual. This paper is based on experience and lessons learned through this process on both the VISTA and the ATST projects.

ENCOAL mild coal gasification project public design and construction report  

SciTech Connect

This Public Design Report describes the 1000 ton per day ENCOAL mild coal gasification demonstration plant now in operation at the Buckskin Mine near Gillette, Wyoming. The objective of the project is to demonstrate that the proprietary Liquids From Coal (LFC) technology can reliably and economically convert low Btu PRB coal into a superior, high-Btu solid fuel (PDF), and an environmentally attractive low-sulfur liquid fuel (CDL). The Project`s plans also call for the production of sufficient quantities of PDF and CDL to permit utility companies to carry out full scale burn tests. While some process as well as mechanical design was done in 1988, the continuous design effort was started in July 1990. Civil construction was started in October 1990; mechanical erection began in May 1991. Virtually all of the planned design work was completed by July 1991. Most major construction was complete by April 1992 followed by plant testing and commissioning. Plant operation began in late May 1992. This report covers both the detailed design and initial construction aspects of the Project.

Design and construction of a deep slurry trench barrier  

SciTech Connect

A 24 m (80 ft) deep slurry trench surrounding a former chromium manufacturing facility on the Patapsco River in Baltimore, Maryland was constructed in 1995 to contain groundwater and site Soils, and to reduce the volume of groundwater extracted to maintain an inward gradient. In 1992, an embankment made of crushed stone was constructed in the Patapsco River to make land for barrier construction outboard of the bulkheads, and to protect the barrier. Stability of the slurry-supported trench excavation in the embankment required construction from an elevated work platform. An extended reach backhoe was used to excavate the deep slurry trench and to clean the trench bottom. Soil-Bentonite backfill was prepared at a central mixing area and transported by truck to the perimeter barrier. A synthetic membrane was inserted partially into the backfill for connection to a multimedia cap, and for redundancy and erosion control in the tidal zone. Hydraulic testing of the aquitard contained by the barrier demonstrated excellent performance of the barrier and bottom closure. Detailed definition of subsurface conditions and the closure stratum was necessary for the design and successful construction of the barrier, and is recommended for comparable slurry trench construction projects.

Design and construction techniques for permeable reactive barriers.  

PubMed

Adequate site characterization, bench-scale column testing, and hydrogeologic modeling formed the basis for the design and construction of permeable reactive barriers for groundwater remediation at various sites, such as Dover Air Force Base, DE and Naval Air Station, Moffett Field, CA. Dissolved chlorinated solvents, such as perchloroethylene (PCE) and trichloroethylene (TCE), have been the focus at many sites because the passive nature of the reactive barrier operation makes such barriers particularly useful for treating groundwater contaminants that can persist in the aquifer for several years. A combination of conventional and innovative site characterization, design, and construction techniques were used at these sites to increase the potential cost effectiveness of field application.

Design, Construction and Operation of a Light Gas Gun  

NASA Astrophysics Data System (ADS)

In order to conduct Richtmyer-Meshkov instability experiments in shock accelerated thin liquid sheets, a light gas gun was designed and constructed at Marquette University. This paper contains the basic predictions and construction techniques utilized in the design and operation of a double diaphragm light gas gun. The compressed air gas gun is used to accelerate a nylon projectile up to a velocity of 300 m/s. Pretest simulations were performed using two different hydrodynamic computational codes in order to simulate the inboard gas dynamics and projectile velocity. These simulations are compared with post test projectile velocity data. The simulations compare favorably to the data, including the one-dimensional calculations which do not account for frictional losses or diameter changes between the breech and barrel. Finally, both the computational simulations and the experimental measurements are compared to simple analytical predictions of the projectile velocity.

In this paper, we rely on the philosophy of Constructal design as applied physics, in order to uncover two fundamental features of evolutionary design for pedestrian evacuation from rectangular areas (e.g., lecture halls with seated occupants). First, the paper shows analytically that the aspect ratio of the floor area can be selected such that the total evacuation time is minimal. Second, the shape of the floor area of each aisle can be tapered such that the total evacuation time is decreased further. These two architectural features are confirmed by means of extensive and systematic numerical simulations of pedestrian evacuation, by using two numerical packages (Simulex and FDS + Evac).

Design and Construction of a Scaled Whirl Tower Facility  

NASA Astrophysics Data System (ADS)

Experimental development of helicopter rotors requires centrifugal testing before entry into a wind tunnel or flight test campaign. This centrifugal testing is performed on test rigs called whirl towers. These facilities are very rare, in fact there were none available in Canada at the time of writing this thesis, but they are very valuable experimental research tools. This thesis describes the design and construction of a whirl tower facility for the centrifugal testing of scaled helicopter rotors with actively controlled systems for reducing vibration. First, the trade-offs between the desired capabilities for the facility to be designed are reviewed, leading to the identification of a set of design requirements. Following this, various concepts for the drive system, frame, data acquisition, and safety infrastructure are proposed. From these, a final design is assembled, whose main advantage is its flexibility and robustness for developmental research. The whirl tower is capable of testing single or multi-bladed rotors (up to four blades), with blades between 1.0 and 1.6 m radius, up to 1,800 RPM frequency with no 'dead zones'. The whirl tower is equipped with a 60 HP, 575 V, AC motor, with flexible coupling and direct drive to the scaled rotor hub. The facility also features a digital telemetry system, slip rings for power and signal transmission for active control, interchangeable rotor heads with variable root distance, and a containment wall for protection from possible rotor blade failures. The manufacturing and construction of the facility, as well as its installation at the National Research Council in Ottawa, is described in detail.

Design and Construction of the Plasma Bubble Expansion Experiment  

NASA Astrophysics Data System (ADS)

We will present the design and construction of a new compact coaxial magnetized plasma gun and its associated hardware systems. The plasma gun will be used for experimental studies of ``magnetic bubble'' expansion into a pre-existing lower density background plasma on the HELCAT facility at UNM. These experiments will address key nonlinear plasma physics issues pertinent to plasma models of the formation and evolution of extra-galactic radio lobes. The gun will be powered by a 120?F 10kV ignitron-switched capacitor bank. High pressure gas, controlled by a gas valve system, will be puffed into an annular gap between inner and outer coaxial electrodes. An applied high voltage ionizes the gas and creates a radial current sheet. The ˜ 100kA discharge current generates toroidal flux, and an external magnet will provide poloidal ``bias'' flux. This poster will describe in detail the design and construction of the various power systems for the new plasma gun source.

The Discovery Channel Telescope: Construction and Design Progress, June 2006  

NASA Astrophysics Data System (ADS)

The Discovery Channel Telescope (DCT) is a 4.2m telescope under construction in northern Arizona. The DCT is located at a new site near Happy Jack at 2361m elevation, which was selected following a lengthy site testing campaign that demonstrated median ground-level seeing of 0.84-arcsec FWHM. The DCT science mission includes targeted studies of astrophysical and solar system objects utilizing RC and Nasmyth-mounted imaging and spectroscopic instrumentation, and wide-field surveys of KBO’s, Centaurs, NEA’s, and other time-variable objects with a 2-degree FOV prime focus camera.The DCT facility enclosure and control building will be completed this year, including the supports for the telescope mount and dome, the major infrastructure for facility machinery, the instrument laboratory, control and computer rooms, and the auxiliary building for the mirror coating facility. Meanwhile, the 4.3m ULE meniscus primary mirror blank was completed at Corning, Inc., in October 2005, and the 2-3 year mirror figuring effort is due to begin June 2006. The primary mirror and its design support, and the preliminary integrated telescope mount model, were finite-element analyzed to optimize the design of the mirror and top-end support configurations. The prime focus camera design has been refined to achieve atmospheric dispersion-compensated 0.25-arcsec images at 1-degree field radius, from B to I-band, at reduced cost through simplification of glasses to standard types and utilization of spheres on all but two lens surfaces.The Discovery Channel Telescope is a project of the Lowell Observatory with major financial support from Discovery Communications, Inc. (DCI). DCI plans ongoing television programming featuring the construction of the telescope and the research ultimately conducted with the DCT. Lowell Observatory is actively seeking additional partners in the project; interested parties should contact R. L. Millis, Director.

Design, construction and evaluation of solarized airlift tubular photobioreactor  

NASA Astrophysics Data System (ADS)

An innovative photobioreactor is developed for growing algae in simulated conditions. The proposed design comprises of a continuous tubular irradiance loop and air induced liquid circulation with gas separation through air lift device. The unique features of air lift system are to ensure the shear free circulation of sensitive algal culture and induce light/dark cycles to the photosynthetic micro-organisms. The design strategy employs to model and construct a 20-liter laboratory scale unit using Boro-silicate glass tubing. The material is selected to ensure maximum photon transmission. All components of the device are designed to have flexibility to be replaced with an alternative design, providing fair chance of modification for future investigators. The principles of fluid mechanics are applied to describe geometrical attributes of the air lift system. Combination of LEDs and Florescent tube lights (Warm white) were used to illuminate the photosynthesis reaction area providing a possibility to control both illumination duration and light intensity. 200 Watt Solar PV system is designed to power up the device which included air pump (100 Watt) and illumination system (100 Watt). Algal strain Chlorella sp was inoculated in photobioreactor which was sparged with air and carbon dioxide. The growth was sustained in the batch mode with daily monitoring of temperature, pH and biomass concentration. The novel photobioreactor recorded a maximum experimental average yield of 0.65 g/l.day (11.3 g/m2.day) as compared to theoretical modeled yield of 0.82 g/l.day (14.26 g/m2.day), suggesting the device can be efficiently and cost-effectively employed in the production of algal biomass for biofuels, concomitantly mitigating CO2.

Constructal method to optimize solar thermochemical reactor design  

SciTech Connect

The objective of this study is the geometrical optimization of a thermochemical reactor, which works simultaneously as solar collector and reactor. The heat (concentrated solar radiation) is supplied on a small peripheral surface and has to be dispersed in the entire reactive volume in order to activate the reaction all over the material. A similarity between this study and the point to volume problem analyzed by the constructal approach (Bejan, 2000) is evident. This approach was successfully applied to several domains, for example for the coupled mass and conductive heat transfer (Azoumah et al., 2004). Focusing on solar reactors, this work aims to apply constructal analysis to coupled conductive and radiative heat transfer. As a first step, the chemical reaction is represented by a uniform heat sink inside the material. The objective is to optimize the reactor geometry in order to maximize its efficiency. By using some hypothesis, a simplified solution is found. A parametric study provides the influence of different technical and operating parameters on the maximal efficiency and on the optimal shape. Different reactor designs (filled cylinder, cavity and honeycomb reactors) are compared, in order to determine the most efficient structure according to the operating conditions. Finally, these results are compared with a CFD model in order to validate the assumptions. (author)

White Oak Creek embayment sediment retention structure design and construction  

SciTech Connect

White Oak Creek is the major surface water drainage throughout the Department of Energy (DOE) Oak Ridge National Laboratory (ORNL). Samples taken from the lower portion of the creek revealed high levels of Cesium 137 and lower level of Cobalt 60 in near surface sediment. Other contaminants present in the sediment included: lead, mercury, chromium, and PCBs. In October 1990, DOE, US Environmental Protection Agency (EPA), and Tennessee Department of Environment and Conservation (TDEC) agreed to initiate a time critical removal action in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to prevent the transport of the contaminated sediments into the Clinch River system. This paper discusses the environmental, regulatory, design, and construction issues that were encountered in conducting the remediation work.

NASA Astrophysics Data System (ADS)

The IRAIT (International Robotic Antarctic Infrared Telescope) project (Tosti et al. 2006) is based on a 80 cm aperture telescope to observe in the infrared range. It is due to start operations in spring 2008, several months after installation in Dome C (Antarctica). We describe the contributions made to such project by the Institute for Space Studies of Catalonia (IEEC) and the University of Granada, whose participation has been mainly focused in developing the moving optical system for the secondary (M2) and tertiary (M3) mirrors of the telescope. Moving parts of the optical system provide focusing and chopping capabilities, implemented in M2, and a rotation mechanism, implemented in M3, allow observation in either Nasmyth foci. The work package includes the design and construction of both mirrors, the mechanical supports, the electronics and the control software, all prepared to work at the low temperatures at Antarctica. A Spanish company, NTE, was contracted to carry out the design and manufacture. Tests at low temperature and integration in the telescope were finished during summer 2006, before sending the telescope to Antarctica, scheduled by the end of the same year.

Chapter 9: The FTU Machine - Design Construction and Assembly  

SciTech Connect

The main design features and guidelines for the construction of the 8-T cryogenically cooled Frascati Tokamak Upgrade (FTU) are presented. The main features include the very compact toroidal magnets based on the concept of the 'Bitter' type of coil with wedge-shaped turns, utilized for the first time for the Alcator A and C magnets, and the original configuration of the vacuum vessel (VV) structure, which is fully welded in order to achieve the required high strength and electric resistivity. The present toroidal limiter has been installed following several years of operation, and this installation has required the development of specific remote-handling tools. The toroidal limiter consists of 12 independent sectors made of stainless steel carriers and molybdenum alloy (TZM) tiles. The main fabrication processes developed for the toroidal and poloidal coils as well as for the VV are described. It is to be noted that the assembly procedure has required very accurate machining of all the structures requiring several trials and steps. The machine has shown no problem in operating routinely at its maximum design values (8 T, 1.6 MA)

Organ procurement from executed prisoners in china.  

PubMed

Organ procurement from executed prisoners in China is internationally condemned, yet this practice continues unabated in 2014. This is despite repeated announcements from Chinese authorities that constructive measures have been undertaken to conform to accepted ethical standards. While there is unanimous agreement on the unethical nature of using organs from executed prisoners, due to its limitations on voluntary and informed consent, there is insufficient coverage of forced organ procurement from prisoners of conscience without consent. Strategies to influence positive change in China over the last few decades have failed to bring this practice to an end. While organ donation and transplantation services in China have undergone considerable structural changes in the last few years, fundamental attempts to shift practice to ethically sourced organs have floundered. In this article, we discuss the organ trade in China, reflect upon organ procurement from executed prisoners (including both capital prisoners and prisoners of conscience) and provide an overview of contradictory Chinese efforts to halt forced organ procurement from executed prisoners. Finally, we highlight current actions being taken to address this issue and offer comprehensive recommendations to bring this ethically indefensible practice to an immediate end. PMID:25059474

DESIGN AND CONSTRUCTION OF A FORCE-REFLECTING TELEOPERATION SYSTEM  

SciTech Connect

For certain applications, such as space servicing, undersea operations, and hazardous material handling tasks in nuclear reactors, the environments can be uncertain, complex, and hazardous. Lives may be in danger if humans were to work under these conditions. As a result, a man-machine system--a teleoperator system--has been developed to work in these types of environments. In a typical teleoperator system, the actual system operates at a remote site; the operator located away from this system usually receives visual information from a video image and/or graphical animation on the computer screen. Additional feedback, such as aural and force information, can significantly enhance performance of the system. Force reflection is a type of feedback in which forces experienced by the remote manipulator are fed back to the manual controller. Various control methods have been proposed for implementation on a teleoperator system. In order to examine different control schemes, a one Degree-Of-Freedom (DOF) Force-Reflecting Manual Controller (FRMC) is constructed and integrated into a PC. The system parameters are identified and constructed as a mathematical model. The Proportional-Integral-Derivative (PID) and fuzzy logic controllers are developed and tested experimentally. Numerical simulation results obtained from the mathematical model are compared with those of experimental data for both types of controllers. In addition, the concept of a telesensation system is introduced. A telesensation system is an advanced teleoperator system that attempts to provide the operator with sensory feedback. In this context, a telesensation system integrates the use of a Virtual Reality (VR) unit, FRMC, and Graphical User Interface (GUI). The VR unit is used to provide the operator with a 3-D visual effect. Various commercial VR units are reviewed and features compared for use in a telesensation system. As for the FRMC, the conceptual design of a 3-DOF FRMC is developed in an effort to make the system portable, compact, and lightweight. A variety of design alternatives are presented and evaluated. Finally, a GUI software package is developed to interface with several teleoperation unit components. These components include an industrial robot, electric motor, encoder, force/torque sensor, and CCD camera. The software includes features such as position scaling, force scaling, and rereferencing and is intended to provide a sound basis for the development of a multi-DOF FRMC system in the future.

Photovoltaic procurement strategies: an assessment of supply issues  

SciTech Connect

This review report presents the results of an analysis of alternative approaches to the design of a federal photovoltaics procurement program. Advantages and disadvantages of large purchases at fixed prices and smaller purchases for testing and demonstrating the technology are presented. The objectives and possible impacts of these purchase programs on the photovoltaic industry are described. The reactions of the industry to alternative purchase programs were assessed using personal interviews with selected companies currently active in photovoltaics. The report begins with a review of the impacts of federal procurements on other innovations, including the electronics industry, and suggests the relation of these procurements to photovoltaics. The methodology for conducting the interviews is presented next. The results of the interviews are summarized into possible scenarios of future developments in the industry and into discussions of key issues in the design of a procurement program. An appendix on the current structure of the photovoltaic industry is provided.

From molecular design and materials construction to organic nanophotonic devices.  

PubMed

Conspectus Nanophotonics has recently received broad research interest, since it may provide an alternative opportunity to overcome the fundamental limitations in electronic circuits. Diverse optical materials down to the wavelength scale are required to develop nanophotonic devices, including functional components for light emission, transmission, and detection. During the past decade, the chemists have made their own contributions to this interdisciplinary field, especially from the controlled fabrication of nanophotonic molecules and materials. In this context, organic micro- or nanocrystals have been developed as a very promising kind of building block in the construction of novel units for integrated nanophotonics, mainly due to the great versatility in organic molecular structures and their flexibility for the subsequent processing. Following the pioneering works on organic nanolasers and optical waveguides, the organic nanophotonic materials and devices have attracted increasing interest and developed rapidly during the past few years. In this Account, we review our research on the photonic performance of molecular micro- or nanostructures and the latest breakthroughs toward organic nanophotonic devices. Overall, the versatile features of organic materials are highlighted, because they brings tunable optical properties based on molecular design, size-dependent light confinement in low-dimensional structures, and various device geometries for nanophotonic integration. The molecular diversity enables abundant optical transitions in conjugated ?-electron systems, and thus brings specific photonic functions into molecular aggregates. The morphology of these micro- or nanostructures can be further controlled based on the weak intermolecular interactions during molecular assembly process, making the aggregates show photon confinement or light guiding properties as nanophotonic materials. By adoption of some active processes in the composite of two or more materials, such as energy transfer, charge separation, and exciton-plasmon coupling, a series of novel nanophotonic devices could be achieved for light signal manipulation. First, we provide an overview of the research evolution of organic nanophotonics, which arises from attempts to explore the photonic potentials of low-dimensional structures assembled from organic molecules. Then, recent advances in this field are described from the viewpoints of molecules, materials, and devices. Many kinds of optofunctional molecules are designed and synthesized according to the demands in high luminescence yield, nonlinear optical response, and other optical properties. Due to the weak interactions between these molecules, numerous micro- or nanostructures could be prepared via self-assembly or vapor-deposition, bringing the capabilities of light transport and confinement at the wavelength scale. The above advantages provide great possibilities in the fabrication of organic nanophotonic devices, by rationally combining these functional components to manipulate light signals. Finally, we present our views on the current challenges as well as the future development of organic nanophotonic materials and devices. This Account gives a comprehensive understanding of organic nanophotonics, including the design and fabrication of organic micro- or nanocrystals with specific photonic properties and their promising applications in functional nanophotonic components and integrated circuits.

This paper analyzes the tasks and problem solving methods used by an engineer in constructing a failure management expert system from design information about the device to te diagnosed. An expert test engineer developed a trouble-shooting expert system based on device design information and experience with similar devices, rather than on specific expert knowledge gained from operating the device or troubleshooting its failures. The construction of the expert system was intensively observed and analyzed. This paper characterizes the knowledge, tasks, methods, and design decisions involved in constructing this type of expert system, and makes recommendations concerning tools for aiding and automating construction of such systems.

It provides not only on-line access, but also schedules procurement actions, monitors their progress, and updates Forecast Award Dates. Except for a few computational routines coded in FORTRAN, the majority of the systems is coded in a high level language called NATURAL. A relational Data Base Management System called ADABAS is utilized. Certain fields, called descriptors, are set up on each file to allow the selection of records based on a specified value or range of values. The use of like descriptors on different files serves as the link between the falls, thus producing a relational data base. Twenty related files are currently being maintained on PROMIS.

The design and construction of a scour monitoring system  

NASA Astrophysics Data System (ADS)

A study is presented to investigate a magnetostrictive flow sensor for use in a scour monitoring system. Using a thin Galfenol "whisker" a sensor is constructed to detect the presence of water flow. Due to the desire for the whisker to respond dynamically rather than with just a quasi-static deflection when in a steady stream of flowing water, two configurations of the sensor are tested, one in which only the bare whisker is exposed to the water flow and one in which an unstable airfoil is fixed to the whisker. Three primary conclusions are inferred. First, the study confirms that Galfenol has the structural properties necessary to create a tactile sensor. Second it has been demonstrated that this tactile sensor is capable of being sensitive to water flow. Finally, it has been determined that alterations to the geometry of the whisker, specifically the addition of an unstable airfoil, can create the necessary dynamic response required for such a sensor.

Design, construction, alignment, and calibration of a compact velocimetry experiment  

SciTech Connect

A velocimetry experiment has been designed to measure shock properties for small, cylindrical, metal targets (8 mm diameter × 2 mm thick). A target is accelerated by high explosives, caught, then retrieved for later inspection. The target is expected to move at a velocity of 0.1 to 3 km/sec. The complete experiment canister is ~105 mm in diameter and 380 mm long. Optical velocimetry diagnostics include the Velocity Interferometer System for Any Reflector (VISAR) and photon Doppler velocimetry (PDV). The packaging of the velocity diagnostics is not allowed to interfere with the foam catchment or an X-ray imaging diagnostic. Using commercial lenses, a single optical relay collects Doppler-shifted light for both VISAR and PDV. The use of fiber optics allows measurement of point velocities on the target surface for accelerations lasting for 3 mm of travel. Operating at 532 nm, the VISAR has separate illumination fibers requiring alignment. The PDV diagnostic operates at 1550 nm but is aligned and calibrated at 670 nm. VISAR and PDV diagnostics are complimentary measurements that image spots in close proximity on the target surface. Because the optical relay uses commercial glass, optical fibers’ axial positions are offset to compensate for chromatic aberrations. The optomechanical design requires careful attention to fiber management, mechanical assembly and disassembly, foam catchment design, and X-ray diagnostic field of view.Calibration and alignment data are archived at each assembly sequence stage. The photon budgets for the VISAR and PDV diagnostics are separately estimated.

The Design and Construction of the MICE Spectrometer Solenoids  

SciTech Connect

The purpose of the MICE spectrometer solenoid is to provide a uniform field for a scintillating fiber tracker. The uniform field is produced by a long center coil and two short end coils. Together, they produce 4T field with a uniformity of better than 1% over a detector region of 1000 mm long and 300 mm in diameter. Throughout most of the detector region, the field uniformity is better than 0.3%. In addition to the uniform field coils, we have two match coils. These two coils can be independently adjusted to match uniform field region to the focusing coil field. The coil package length is 2544 mm. We present the spectrometer solenoid cold mass design, the powering and quench protection circuits, and the cryogenic cooling system based on using three cryocoolers with re-condensers.

The GLAST large area telescope: Design, construction, test and calibration  

NASA Astrophysics Data System (ADS)

The Gamma-ray Large Area Space Telescope (GLAST) is an international, multi-agency satellite mission with a vast and ambitious physics program in gamma-ray astronomy, particle astrophysics and cosmology. The Large Area Telescope (LAT) is the main instrument onboard GLAST and will detect high energy gamma rays with unprecedented resolution and sensitivity. After successful integration of the three detector subsystems—a silicon-strip tracker-converter, a CsI imaging calorimeter and an outer plastic scintillator serving as anti-coincidence detector—into the telescope, the LAT was installed on the satellite in preparation for the January 2008 launch. Highlights of the LAT instrument performance and of the main technological challenges encountered during the telescope design, commissioning and calibration phases are discussed here, as well as their impact on the mission discovery potential.

Design, Construction, Alignment, and Calibration of a Compact Velocimetry Experiment  

SciTech Connect

A velocimetry experiment has been designed to measure shock properties for small cylindrical metal targets (8-mm-diameter by 2-mm thick). A target is accelerated by high explosives, caught, and retrieved for later inspection. The target is expected to move at a velocity of 0.1 to 3 km/sec. The complete experiment canister is approximately 105 mm in diameter and 380 mm long. Optical velocimetry diagnostics include the Velocity Interferometer System for Any Reflector (VISAR) and Photon Doppler Velocimetry (PDV). The packaging of the velocity diagnostics is not allowed to interfere with the catchment or an X-ray imaging diagnostic. A single optical relay, using commercial lenses, collects Doppler-shifted light for both VISAR and PDV. The use of fiber optics allows measurement of point velocities on the target surface during accelerations occurring over 15 mm of travel. The VISAR operates at 532 nm and has separate illumination fibers requiring alignment. The PDV diagnostic operates at 1550 nm, but is aligned and focused at 670 nm. The VISAR and PDV diagnostics are complementary measurements and they image spots in close proximity on the target surface. Because the optical relay uses commercial glass, the axial positions of the optical fibers for PDV and VISAR are offset to compensate for chromatic aberrations. The optomechanical design requires careful attention to fiber management, mechanical assembly and disassembly, positioning of the foam catchment, and X-ray diagnostic field-of-view. Calibration and alignment data are archived at each stage of the assembly sequence.

100 Years of Embankment Dam Design and Construction in the U.S. Bureau of Reclamation  

E-print Network

The design and construction of earthfill and rockfill embankment dams in the Western United States have evolved dramatically during the past 100 years (1902-2002). The U.S. Department of the Interior’s Bureau of Reclamation (Reclamation) has played a significant role in that evolution of embankment dam engineering, construction, and dam safety during the 20 th Century. There are now over 240 water-storage embankment dams in the Western United States that were designed and constructed by Reclamation. The list of civil engineers and other professionals who have helped to design and build Reclamation’s embankment dams is lengthy and highly regarded. This paper discusses Reclamation’s embankment dam design and construction organizations and how they have evolved during the past century. Starting in 1902, Reclamation's embankment dam design and construction approach involved one engineer in charge of all phases of the work, from development of the project all the way through design and construction of the dam and appurtenant structures.

Spiral 2 cryogenic system overview: Design, construction and performance test  

SciTech Connect

The new particle accelerator project Spiral 2 at GANIL (“Grand Accélérateur d’Ions Lourds, i.e. National Large Heavy Ion Accelerator) in Caen (France) is a very large installation, intended to serve fundamental research in nuclear physics. The heart of the future machine features a superconductor linear accelerator, delivering a beam until 20Mev/A, which are then used to bombard a matter target. The resulting reactions, such as fission, transfer, fusion, etc. will generate billions of exotic nuclei. To achieve acceleration of the beam, 26 cavities which are placed inside cryomodules at helium cryogenic temperature will be used. AL-AT (Air Liquide Advanced Technologies) takes part to the project by supplying cryogenic plant. The plant includes the liquefier associated to its compressor station, a large dewar, a storage tank for helium gas and transfer lines. In addition, a helium recovery system composed of recovery compressor, high pressure storage and external purifier has been supplied. Customized HELIAL LF has been designed, manufactured and tested by AL-AT to match the refrigeration power need for the Spiral 2 project which is around 1300 W equivalent at 4.5 K.

Design and construction of drift tube linac cavities for RIKEN RI Beam Factory  

NASA Astrophysics Data System (ADS)

A new injector linac "RILAC2", has recently been constructed at the RIKEN RI Beam Factory. The main part of the RILAC2 is a drift tube linac that consists of three newly designed cavities. These cavities operate in continuous wave (CW) mode at a fixed frequency of 36.5 MHz. Their structure is based on a quarter-wavelength resonator because this is the smallest resonator available in this frequency range among the available structures. We adopted the direct coupling method in the construction of these cavities. A power amplifier was directly coupled to the cavity without a long transmission line to reduce the installation area and simultaneously reduce construction cost. A detailed cavity and coupler design was carried out via simulation. Our work also describes the design process using three-dimensional electromagnetic simulation software. Construction and operation tests are also shown.

In this study we examine design rules for efficient gene silencing, in terms of both the proportion of independent transgenic plants showing

Design and construction of a remote piloted flying wing. B.S. Thesis  

NASA Technical Reports Server (NTRS)

Currently, there is a need for a high-speed, high-lift civilian transport. Although unconventional, a flying wing could fly at speeds in excess of Mach 2 and still retain the capacity of a 747. The design of the flying wing is inherently unstable since it lacks a fuselage and a horizontal tail. The project goal was to design, construct, fly, and test a remote-piloted scale model flying wing. The project was completed as part of the NASA/USRA Advanced Aeronautics Design Program. These unique restrictions required us to implement several fundamental design changes from last year's Elang configuration including wing sweepback and wingtip endplates. Unique features such as a single ducted fan engine, composite structural materials, and an electrostatic stability system were incorporated. The result is the Banshee '94. Our efforts will aid future projects in design and construction techniques so that a viable flying wing can become an integral part of the aviation industry.

Design and Construction Solutions in the Accurate Realization of NCSX Magnetic Fields  

SciTech Connect

The National Compact Stellarator Experiment, NCSX, is being constructed at the Princeton Plasma Physics Laboratory (PPPL) in partnership with the Oak Ridge national Laboratory. The goal of NCSX is to provide the understanding necessary to develop an attractive, disruption free, steady state compact stellaratorbased reactor design. This paper describes the recently revised designs of the critical interfaces between the modular coils, the construction solutions developed to meet assembly tolerances, and the recently revised trim coil system that provides the required compensation to correct for the “as built” conditions and to allow flexibility in the disposition of as-built conditions. In May, 2008, the sponsor decided to terminate the NCSX project due to growth in the project’s cost and schedule estimates. However significant technical challenges in design and construction were overcome, greatly reducing the risk in the remaining work to complete the project.

Design and implementation of an identification system in construction site safety for proactive accident prevention.  

PubMed

Identifying accident precursors using real-time identity information has great potential to improve safety performance in construction industry, which is still suffering from day to day records of accident fatality and injury. Based on the requirements analysis for identifying precursor and the discussion of enabling technology solutions for acquiring and sharing real-time automatic identification information on construction site, this paper proposes an identification system design for proactive accident prevention to improve construction site safety. Firstly, a case study is conducted to analyze the automatic identification requirements for identifying accident precursors in construction site. Results show that it mainly consists of three aspects, namely access control, training and inspection information and operation authority. The system is then designed to fulfill these requirements based on ZigBee enabled wireless sensor network (WSN), radio frequency identification (RFID) technology and an integrated ZigBee RFID sensor network structure. At the same time, an information database is also designed and implemented, which includes 15 tables, 54 queries and several reports and forms. In the end, a demonstration system based on the proposed system design is developed as a proof of concept prototype. The contributions of this study include the requirement analysis and technical design of a real-time identity information tracking solution for proactive accident prevention on construction sites. The technical solution proposed in this paper has a significant importance in improving safety performance on construction sites. Moreover, this study can serve as a reference design for future system integrations where more functions, such as environment monitoring and location tracking, can be added. PMID:22664682

Review of Qualitative Approaches for the Construction Industry: Designing a Risk Management Toolbox  

PubMed Central

Objectives This paper presents the framework and protocol design for a construction industry risk management toolbox. The construction industry needs a comprehensive, systematic approach to assess and control occupational risks. These risks span several professional health and safety disciplines, emphasized by multiple international occupational research agenda projects including: falls, electrocution, noise, silica, welding fumes, and musculoskeletal disorders. Yet, the International Social Security Association says, "whereas progress has been made in safety and health, the construction industry is still a high risk sector." Methods Small- and medium-sized enterprises (SMEs) employ about 80% of the world's construction workers. In recent years a strategy for qualitative occupational risk management, known as Control Banding (CB) has gained international attention as a simplified approach for reducing work-related risks. CB groups hazards into stratified risk 'bands', identifying commensurate controls to reduce the level of risk and promote worker health and safety. We review these qualitative solutions-based approaches and identify strengths and weaknesses toward designing a simplified CB 'toolbox' approach for use by SMEs in construction trades. Results This toolbox design proposal includes international input on multidisciplinary approaches for performing a qualitative risk assessment determining a risk 'band' for a given project. Risk bands are used to identify the appropriate level of training to oversee construction work, leading to commensurate and appropriate control methods to perform the work safely. Conclusion The Construction Toolbox presents a review-generated format to harness multiple solutions-based national programs and publications for controlling construction-related risks with simplified approaches across the occupational safety, health and hygiene professions.

Palliative physicians persuade procurators fiscal.  

PubMed

Mesothelioma caused by occupational exposure to asbestos is well recognized and sufferers who have been employed in a prescribed occupation can claim compensation. Stringent criteria must be fulfilled in order to establish the link between occupational exposure and mesothelioma, and to this end the procurator fiscal is involved after the patient's death, both to elucidate the individual situation and 'for the common good'. Problems were experienced locally by the use of uniformed police officers, as the appointed Crown agents, as interviewers of recently bereaved relatives, irrespective of the degree of tact and sensitivity shown. The likelihood of an autopsy was also distressing. It is important to recognize the role of the procurator fiscal and to ensure that workers' compensation procedures exist and are followed. However, in order to minimize grief and distress to relatives, discussion took place with the local procurator fiscal. He was appreciative of the issues raised and practice has now changed substantially. In particular, police officers are no longer required to interview relatives either for the purpose of identification or to ascertain the deceased's occupational history. A pro forma has been produced and agreed locally to obviate the need for medical staff to be interviewed by police officers. Following subsequent discussion with the Crown Office our local arrangements have been incorporated in Crown Office guidance for national use. PMID:12465702

The constructal-law origin of the wheel, size, and skeleton in animal design  

NASA Astrophysics Data System (ADS)

This paper shows that the emergence of body organs is predictable as an integral part of the design for moving animal mass more easily on Earth, in accord with the constructal law of design in nature: For a finite-size open system to persist in time (to live), it must evolve such that it provides easier access to the imposed (global) currents that flow through it. Every organ destroys useful energy in two ways: Internally by thermodynamic irreversibilities and by having to be carried. From the constructal law follows the necessity of characteristic-size organs and the emergence of solid columns (legs) to facilitate the flow of stresses. This natural "wheel" endows the body with rolling (falling-forward) locomotion, with predicted speeds that agree with the observed speeds in the body mass range of 10-6-103 kg. The constructal law also accounts for animal design features for changing speeds. Skeletons (bones and legs) are solid organs that emerge in accordance with the constructal-law design of moving animal mass: More and stronger material emerges along the lines of highest stresses. A connection between animal wheel movement and swimming, water waves, and tsunamis is also made.

The paper presents the prototype of an YBCO superferric quadrupolar magnet for high gradient magnetic field generation, design and construction. The temperature of the superconducting coil has to be kept within safe limits or the HTS would exit the superconductive state. Of particular concern is the "warm" beam tube that passes through the magnet. Cryogenic conduction cooling with a closed cycle G-M Cooler may ensure the removal of the ambient heat influx. Numerical simulation results on the magnetic field and heat transfer problems are then discussed. The computational domain is abstracted out of the CAD design of the system. The design solution is presented and compared with the numerical simulations results.

A supermolecular building approach for the design and construction of metal-organic frameworks.  

PubMed

In this review, we describe two recently implemented conceptual approaches facilitating the design and deliberate construction of metal–organic frameworks (MOFs), namely supermolecular building block (SBB) and supermolecular building layer (SBL) approaches. Our main objective is to offer an appropriate means to assist/aid chemists and material designers alike to rationally construct desired functional MOF materials, made-to-order MOFs. We introduce the concept of net-coded building units (net-cBUs), where precise embedded geometrical information codes uniquely and matchlessly a selected net, as a compelling route for the rational design of MOFs. This concept is based on employing pre-selected 0-periodic metal–organic polyhedra or 2-periodic metal–organic layers, SBBs or SBLs respectively, as a pathway to access the requisite net-cBUs. In this review, inspired by our success with the original rht-MOF, we extrapolated our strategy to other known MOFs via their deconstruction into more elaborate building units (namely polyhedra or layers) to (i) elucidate the unique relationship between edge-transitive polyhedra or layers and minimal edge-transitive 3-periodic nets, and (ii) illustrate the potential of the SBB and SBL approaches as a rational pathway for the design and construction of 3-periodic MOFs. Using this design strategy, we have also identified several new hypothetical MOFs which are synthetically targetable. PMID:25009001

Procurement Options for New Renewable Electricity Supply  

SciTech Connect

State renewable portfolio standard (RPS) policies require utilities and load-serving entities (LSEs) to procure renewable energy generation. Utility procurement options may be a function of state policy and regulatory preferences, and in some cases, may be dictated by legislative authority. Utilities and LSEs commonly use competitive solicitations or bilateral contracting to procure renewable energy supply to meet RPS mandates. However, policymakers and regulators in several states are beginning to explore the use of alternatives, namely feed-in tariffs (FITs) and auctions to procure renewable energy supply. This report evaluates four procurement strategies (competitive solicitations, bilateral contracting, FITs, and auctions) against four main criteria: (1) pricing; (2) complexity and efficiency of the procurement process; (3) impacts on developers access to markets; and (4) ability to complement utility decision-making processes. These criteria were chosen because they take into account the perspective of each group of stakeholders: ratepayers, regulators, utilities, investors, and developers.

Constructing a modern cytology laboratory: A toolkit for planning and design  

PubMed Central

Introduction: Constructing or renovating a laboratory can be both challenging and rewarding. UAB Cytology (UAB CY) recently undertook a project to relocate from a building constructed in 1928 to new space. UAB CY is part of an academic center that provides service to a large set of patients, support training of one cytotechnology program and one cytopathology fellowship training program and involve actively in research and scholarly activity. Our objectives were to provide a safe, aesthetically pleasing space and gain efficiencies through lean processes. Methods: The phases of any laboratory design project are Planning, Schematic Design (SD), Design Development (DD), Construction Documents (CD) and Construction. Lab personnel are most critical in the Planning phase. During this time stakeholders, relationships, budget, square footage and equipment were identified. Equipment lists, including what would be relocated, purchased new and projected for future growth ensure that utilities were matched to expected need. A chemical inventory was prepared and adequate storage space was planned. Regulatory and safety requirements were discussed. Tours and high level process flow diagrams helped architects and engineers understand the laboratory daily work. Future needs were addressed through a questionnaire which identified potential areas of growth and technological change. Throughout the project, decisions were driven by data from the planning phase. During the SD phase, objective information from the first phase was used by architects and planners to create a general floor plan. This was the basis of a series of meetings to brainstorm and suggest modifications. DD brings more detail to the plans with engineering, casework, equipment specifics, finishes. Design changes should be completed at this phase. The next phase, CD took the project from the lab purview into purely technical mode. Construction documents were used by the contractor for the bidding process and ultimately the Construction phase. Results: The project fitted out a total of 9,000 square feet; 4,000 laboratory and 5,000 office/support. Lab space includes areas for Prep, CT screening, sign out and Imaging. Adjacent space houses faculty offices and conferencing facilities. Transportation time was reduced (waste removal) by a Pneumatic Tube System, specimen drop window to Prep Lab and a pass thru window to the screening area. Open screening and prep areas allow visual management control. Efficiencies were gained by ergonomically placing CT Manual and Imaging microscopes and computers in close proximity, also facilitating a paperless workflow for additional savings. Logistically, closer proximity to Surgical Pathology maximized the natural synergies between the areas. Conclusions: Lab construction should be a systematic process based on sound principles for safety, high quality testing, and finance. Our detailed planning and design process can be a model for others undertaking similar projects PMID:23599722

Procurement and Maintenance of Germ-Free Swine for Microbiological Investigations1  

PubMed Central

Germ-free swine were routinely procured by both hysterectomy and hysterotomy (Caesarian section). By means of light-weight portable equipment, piglets could be obtained and transported to the laboratory (without contamination) over distances in excess of 100 miles. The isolators employed in rearing were constructed of stainless steel and flexible plastic film. At weekly intervals, fecal swabs and waste from the floor of the isolator were cultured on blood-agar and in thioglycolate broth, as well as being examined microscopically for the presence of bacteria, yeast, and fungi. The presence of pleuropneumonia-like organisms (PPLO) and viruses in such material was not demonstrable, either by the use of enriched PPLO media or primary porcine-kidney cell cultures. Tissues, body fluids, and cecal contents of piglets sacrificed specifically for microbiological examination were also negative for PPLO, viruses, bacteria, yeast, and fungi. Prenatal infestations by ascarids were not observed. Nutritional problems related to rearing of germ-free piglets, such as hypoglycemia, were not encountered, and the use of an autoclaved commercial sow's milk replacer proved quite satisfactory. The temperature to which piglets were subjected during the first few days of life, however, was very important. The isolator design and application of gnotobiotic techniques to the procurement and rearing of a large germ-free animal such as the pig proved feasible and less difficult than anticipated.

LADES: A Software for Constructing and Analyzing Longitudinal Designs in Biomedical Research  

PubMed Central

One of the most important steps in biomedical longitudinal studies is choosing a good experimental design that can provide high accuracy in the analysis of results with a minimum sample size. Several methods for constructing efficient longitudinal designs have been developed based on power analysis and the statistical model used for analyzing the final results. However, development of this technology is not available to practitioners through user-friendly software. In this paper we introduce LADES (Longitudinal Analysis and Design of Experiments Software) as an alternative and easy-to-use tool for conducting longitudinal analysis and constructing efficient longitudinal designs. LADES incorporates methods for creating cost-efficient longitudinal designs, unequal longitudinal designs, and simple longitudinal designs. In addition, LADES includes different methods for analyzing longitudinal data such as linear mixed models, generalized estimating equations, among others. A study of European eels is reanalyzed in order to show LADES capabilities. Three treatments contained in three aquariums with five eels each were analyzed. Data were collected from 0 up to the 12th week post treatment for all the eels (complete design). The response under evaluation is sperm volume. A linear mixed model was fitted to the results using LADES. The complete design had a power of 88.7% using 15 eels. With LADES we propose the use of an unequal design with only 14 eels and 89.5% efficiency. LADES was developed as a powerful and simple tool to promote the use of statistical methods for analyzing and creating longitudinal experiments in biomedical research. PMID:24983945

Competition in the economic crisis: Analysis of procurement auctions  

PubMed Central

We study the effects of the recent economic crisis on firms? bidding behavior and markups in sealed bid auctions. Using data from Austrian construction procurements, we estimate bidders? construction costs within a private value auction model. We find that markups of all bids submitted decrease by 1.5 percentage points in the recent economic crisis, markups of winning bids decrease by 3.3 percentage points. We also find that without the government stimulus package this decrease would have been larger. These two pieces of evidence point to pro-cyclical markups.

Optimization of Structural Design for Sustainable Construction of Transmission Tower Based on Topographical Algorithm  

NASA Astrophysics Data System (ADS)

Optimization of transmission tower structures is traditionally based on either optimization of members sizes with fixed topographical shape or based on structural analysis modelling strategies without taking cognizance of fabrication and constructability issue facing the contractors . This paper look into an integrated optimum design approach strategies whereby size, shape and topology are combined together with the fabrication issues in the construction of the transmission tower. The topographical algorithm is based on changing the inclination degree of the legs of the tower at first with optimum individual members sizing and later rationalized member sizes are performed through member groupings for the ease fabrication and construction of the transmission tower. The optimum weight using topographical algorithm obtained for the transmission tower is 10,924 kg for singular members and 18,430 kg for element grouping at 10° inclination angle.

Conceptual design and analysis of roads and road construction machinery for initial lunar base operations  

NASA Technical Reports Server (NTRS)

Recent developments have made it possible for scientists and engineers to consider returning to the Moon to build a manned lunar base. The base can be used to conduct scientific research, develop new space technology, and utilize the natural resources of the Moon. Areas of the base will be separated, connected by a system of roads that reduce the power requirements of vehicles traveling on them. Feasible road types for the lunar surface were analyzed and a road construction system was designed for initial lunar base operations. A model was also constructed to show the system configuration and key operating features. The alternate designs for the lunar road construction system were developed in four stages: analyze and select a road type; determine operations and machinery needed to produce the road; develop machinery configurations; and develop alternates for several machine components. A compacted lunar soil road was selected for initial lunar base operations. The only machinery required to produce this road were a grader and a compactor. The road construction system consists of a main drive unit which is used for propulsion, a detachable grader assembly, and a towed compactor.

Exploratory studies facility test implementation and integration with construction and design  

SciTech Connect

The Exploratory Studies Facility (ESF) is a critical component of the US Department of Energy`s Yucca Mountain Site Characterization Project Office (YMPO) program to identify and characterize a potentially suitable site for licensing and construction of the nation`s first geologic repository for the disposal of spent nuclear fuel and high-level radioactive waste. The mission of the ESF is to conduct a site characterization program that (1) is fully integrated with ESF design and construction, (2) minimizes potential adverse impacts to other tests, (3) protects waste isolation capabilities of the site, and (4) protects the environment. Tests performed in the ESF include unique, irretrievable data collection and in situ site characterization activities which provide a critical complement to surface-based and laboratory tests. In addition, the site characterization program must ensure that critical, irretrievable data are gathered with minimal impacts to other portions of the project and that a process exists for real-time integration of tests. Underground testing in the ESF began concurrently with construction of the ESF north ramp starter tunnel in 1993. This paper discusses the implementation of ESF north ramp starter tunnel tests, planning and implementation of radial borehole and hydrochemistry tests in the first test alcove, and real-time integration of tests with design, construction, and long-term site characterization test planning.

Design and construction of instrument rotator for the Sloan Digital Sky Survey (SDSS) telescope  

NASA Astrophysics Data System (ADS)

This paper will describe the concerns, parameters and restrictions in the design and construction of the instrument rotator used on the SDSS telescope. The rotator provides support for two 600 Lb. Spectrographs, through all axes motion, without causing harmful radial moments to be translated to its inner ring which supports the mosaic imaging camera. This is accomplished using an outer-inner ring design. The outer ring is a thin-walled box structure incorporating the drive surface and is attached to the inner ring through a steel membrane. This rotator design requires the telescope"s primary support structure to provide final structural integrity. Due to this feature, a special fixture was needed to transport the rotator from the vendor and to install it onto the telescope. Positional accuracy and feedback is provided by an optical tape and read-head system manufactured by Heidenhain and attached to the inner ring. The drive motor was designed to use the same motor as those employed for the other two telescope axes, thus minimizing the spare-parts inventory and maintenance. Its drive pinion is of a pinch design, with the pinion axis parallel to rotator radius. A great deal of attention and planning was required in the construction of the box frame outer ring and the induction heat-treating of the drive surface. Drive surface tolerances were maintained within +/-0.001 inches, and internal stress cracks from heat-treating were minimal.

Large-scale performance and design for construction activity erosion control best management practices.  

PubMed

The National Pollutant Discharge Elimination System (NPDES) Phase II requires construction activities to have erosion and sediment control best management practices (BMPs) designed and installed for site storm water management. Although BMPs are specified on storm water pollution prevention plans (SWPPPs) as part of the construction general permit (GP), there is little evidence in the research literature as to how BMPs perform or should be designed. The objectives of this study were to: (i) comparatively evaluate the performance of common construction activity erosion control BMPs under a standardized test method, (ii) evaluate the performance of compost erosion control blanket thickness, (iii) evaluate the performance of compost erosion control blankets (CECBs) on a variety of slope angles, and (iv) determine Universal Soil Loss Equation (USLE) cover management factors (C factors) for these BMPs to assist site designers and engineers. Twenty-three erosion control BMPs were evaluated using American Society of Testing and Materials (ASTM) D-6459, standard test method for determination of ECB performance in protecting hill slopes from rainfall induced erosion, on 4:1 (H:V), 3:1, and 2:1 slopes. Soil loss reduction for treatments exposed to 5 cm of rainfall on a 2:1 slope ranged from-7 to 99%. For rainfall exposure of 10 cm, treatment soil loss reduction ranged from 8 to 99%. The 2.5 and 5 cm CECBs significantly reduced erosion on slopes up to 2:1, while CECBs < 2.5 cm are not recommended on slopes >or= 4:1 when rainfall totals reach 5 cm. Based on the soil loss results, USLE C factors ranged from 0.01 to 0.9. These performance and design criteria should aid site planners and designers in decision-making processes. PMID:19398523

Improvement of sand filter and constructed wetland design using an environmental decision support system.  

PubMed

With the aim of improving effluent quality of waste stabilization ponds, different designs of vertical flow constructed wetlands and intermittent sand filters were tested on an experimental full-scale plant within the framework of a European project. The information extracted from this study was completed and updated with heuristic and bibliographic knowledge. The data and knowledge acquired were difficult to integrate into mathematical models because they involve qualitative information and expert reasoning. Therefore, it was decided to develop an environmental decision support system (EDSS-Filter-Design) as a tool to integrate mathematical models and knowledge-based techniques. This paper describes the development of this support tool, emphasizing the collection of data and knowledge and representation of this information by means of mathematical equations and a rule-based system. The developed support tool provides the main design characteristics of filters: (i) required surface, (ii) media type, and (iii) media depth. These design recommendations are based on wastewater characteristics, applied load, and required treatment level data provided by the user. The results of the EDSS-Filter-Design provide appropriate and useful information and guidelines on how to design filters, according to the expert criteria. The encapsulation of the information into a decision support system reduces the design period and provides a feasible, reasoned, and positively evaluated proposal. PMID:18574198

Design and construction of an optical computed tomography scanner for polymer gel dosimetry application.  

PubMed

Polymer gel dosimeter is the only accurate three dimensional (3D) dosimeter that can measure the absorbed dose distribution in a perfect 3D setting. Gel dosimetry by using optical computed tomography (OCT) has been promoted by several researches. In the current study, we designed and constructed a prototype OCT system for gel dosimetry. First, the electrical system for optical scanning of the gel container using a Helium-Neon laser and a photocell was designed and constructed. Then, the mechanical part for two rotational and translational motions was designed and step motors were assembled to it. The data coming from photocell was grabbed by the home-built interface and sent to a personal computer. Data processing was carried out using MATLAB software. To calibrate the system and tune up the functionality of it, different objects was designed and scanned. Furthermore, the spatial and contrast resolution of the system was determined. The system was able to scan the gel dosimeter container with a diameter up to 11 cm inside the water phantom. The standard deviation of the pixels within water flask image was considered as the criteria for image uniformity. The uniformity of the system was about ±0.05%. The spatial resolution of the system was approximately 1 mm and contrast resolution was about 0.2%. Our primary results showed that this system is able to obtain two-dimensional, cross-sectional images from polymer gel samples. PMID:24761377

Towards Clinically Optimized MRI-guided Surgical Manipulator for Minimally Invasive Prostate Percutaneous Interventions: Constructive Design*  

PubMed Central

This paper undertakes the modular design and development of a minimally invasive surgical manipulator for MRI-guided transperineal prostate interventions. Severe constraints for the MRI-compatibility to hold the minimum artifact on the image quality and dimensions restraint of the bore scanner shadow the design procedure. Regarding the constructive design, the manipulator kinematics has been optimized and the effective analytical needle workspace is developed and followed by proposing the workflow for the manual needle insertion. A study of the finite element analysis is established and utilized to improve the mechanism weaknesses under some inevitable external forces to ensure the minimum structure deformation. The procedure for attaching a sterile plastic drape on the robot manipulator is discussed. The introduced robotic manipulator herein is aimed for the clinically prostate biopsy and brachytherapy applications. PMID:24683502

Design and construction of a multiwavelength, micromirror total internal reflectance fluorescence microscope.  

PubMed

Colocalization single-molecule spectroscopy (CoSMoS) has proven to be a useful method for studying the composition, kinetics and mechanisms of complex cellular machines. Key to the technique is the ability to simultaneously monitor multiple proteins and/or nucleic acids as they interact with one another. Here we describe a protocol for constructing a CoSMoS micromirror total internal reflection fluorescence microscope (mmTIRFM). Design and construction of a scientific microscope often requires a number of custom components and a substantial time commitment. In our protocol, we have streamlined this process by implementation of a commercially available microscopy platform designed to accommodate the optical components necessary for an mmTIRFM. The mmTIRF system eliminates the need for machining custom parts by the end user and facilitates optical alignment. Depending on the experience level of the microscope builder, these time savings and the following protocol can enable mmTIRF construction to be completed within 2 months. PMID:25188633

Settling basin design in a constructed wetland using TSS removal efficiency and hydraulic retention time.  

PubMed

Using total suspended solid (TSS) removal efficiency and hydraulic retention time (HRT) as design parameters a design guideline of a settling basin in a constructed wetland (CW) was suggested; as well as management of sediment and particle in the settling basin. The CW was designed to treat the piggery wastewater effluent from a wastewater treatment plant during dry days and stormwater runoff from the surrounding paved area during wet days. The first settling basin (FSB) in the CW was theoretically designed with a total storage volume (TSV) of 453m(3) and HRT of 5.5hr. The amount of sediment and particles settled at the FSB was high due to the sedimentation and interception of plants in the CW. Dredging of sediments was performed when the retention rate at the FSB decreased to approximately 80%. Findings showed that the mean flow rate was 21.8m(3)/hr less than the designed flow rate of 82.8m(3)/hr indicating that the FSB was oversize and operated with longer HRT (20.7hr) compared to the design HRT. An empirical model to estimate the length of the settling basin in the CW was developed as a function of HRT and desired TSS removal efficiency. Using the minimum tolerable TSS removal efficiency of 30%, the length of the FSB was estimated to be 31.2m with 11.8hr HRT. PMID:25193826

Lead Coolant Test Facility Technical and Functional Requirements, Conceptual Design, Cost and Construction Schedule  

SciTech Connect

This report presents preliminary technical and functional requirements (T&FR), thermal hydraulic design and cost estimate for a lead coolant test facility. The purpose of this small scale facility is to simulate lead coolant fast reactor (LFR) coolant flow in an open lattice geometry core using seven electrical rods and liquid lead or lead-bismuth eutectic. Based on review of current world lead or lead-bismuth test facilities and research need listed in the Generation IV Roadmap, five broad areas of requirements of basis are identified: Develop and Demonstrate Prototype Lead/Lead-Bismuth Liquid Metal Flow Loop Develop and Demonstrate Feasibility of Submerged Heat Exchanger Develop and Demonstrate Open-lattice Flow in Electrically Heated Core Develop and Demonstrate Chemistry Control Demonstrate Safe Operation and Provision for Future Testing. These five broad areas are divided into twenty-one (21) specific requirements ranging from coolant temperature to design lifetime. An overview of project engineering requirements, design requirements, QA and environmental requirements are also presented. The purpose of this T&FRs is to focus the lead fast reactor community domestically on the requirements for the next unique state of the art test facility. The facility thermal hydraulic design is based on the maximum simulated core power using seven electrical heater rods of 420 kW; average linear heat generation rate of 300 W/cm. The core inlet temperature for liquid lead or Pb/Bi eutectic is 420oC. The design includes approximately seventy-five data measurements such as pressure, temperature, and flow rates. The preliminary estimated cost of construction of the facility is $3.7M. It is also estimated that the facility will require two years to be constructed and ready for operation.

Design and construction of a tensile tester for the testing of simple composites  

NASA Technical Reports Server (NTRS)

The following is a design for a tensile tester which will be used to test the tensile strength and anisotropic properties of simple composites. These simple composites are suspected to be anisotropic primarily in a single plane. When the composites undergo a tensile force, they will undergo deformation, causing movement either to the left or right. The composites are suspect due to their method of construction. Each sample has a single layer of unidirectional continuous fibers embedded in a rubbery resin. It has been well established that a serious limitation of unidirectional fiber composites is the very large in-plane anisotropy. The design presented here incorporates a single degree of freedom such that distortion (to the left or right) due to anisotropic tendencies may be measured. The device will spend the vast majority of its time in an undergraduate materials lab. As a result, ease of use and durability are valued more highly than research grade accuracy. Additional concerns focus on the fact that this machine will be built as a student project. Issues which are dealt with during this design include: specimen configuration or shape; a method of applying consistent, linear tension force; a method of gripping specimen without affecting its overall properties; a method of collecting data; repeatability of data; ease of use; ease of construction; and cost. After the device has been constructed, it will be used to test the simple composites which were fabricated in house. A comparison will be made between composites manufactured using aluminum screening as the strengthening fibers and those manufactured using fiberglass screening.

NASA Astrophysics Data System (ADS)

This paper presents a trailing edge flap actuation mechanism using a novel pre-stressed piezoelectric unimorph, PUMPS (Piezoelectric Unimorph with Mechanically Pre-stressed Substrate). Experimental evaluation of actuation performance such as force-displacement characteristics of PUMPS actuators showed that the performance of PUMPS satisfied the requirements for trailing edge flap actuation. Subsequently, flap actuation mechanisms were designed and constructed with several slot types in the flaps, and stacked PUMPS actuators were applied to the flap actuation mechanisms. Experimental study of the test wing models with four flaps was accomplished, and the flap angle was achieved up to +/-5.5° within 15Hz under maximum applicable voltage.

Design, Construction, and Evaluation of Ni-C Eutectic Fixed Points  

NASA Astrophysics Data System (ADS)

In this article the design, construction, and evaluation of eutectic fixed points for contact and non-contact measurements that have been recently developed at MIRS/UL/FE-LMK are presented. The design of the cells is made in such way that it can be used for only thermocouple calibration in vertical or horizontal furnaces, for calibration of pyrometers in a horizontal furnace, and for simultaneous calibration of contact and non-contact thermometers in a horizontal furnace. Special care has been taken to achieve repeatability and reproducibility of the transition temperatures and mechanical robustness of the cell. This includes also usage of a carbon sleeve in combination with carbon sheets, in a so-called hybrid design of the eutectic cell. With such a design, significant improvement in mechanical robustness of the cell and temperature stability of the cell has been achieved. All the measurements are performed within specially designed seven-zone furnaces within which different gradients, and different heating and cooling rates can be realized. The melting temperature of Ni-C ((1328.44 ± 0.70) °C) measured with a thermocouple type R, calibrated at the zinc, aluminum, silver, copper, and palladium fixed points, and a non-contact thermometer, calibrated by comparison against different blackbodies, agree within their expanded uncertainties of 0.7 °C and 1.5 °C, respectively.

A review on the sustainability of constructed wetlands for wastewater treatment: Design and operation.  

PubMed

Constructed wetlands (CWs) have been used as a green technology to treat various wastewaters for several decades. CWs offer a land-intensive, low-energy, and less-operational-requirements alternative to conventional treatment systems, especially for small communities and remote locations. However, the sustainable operation and successful application of these systems remains a challenge. Hence, this paper aims to provide and inspire sustainable solutions for the performance and application of CWs by giving a comprehensive review of CWs' application and the recent development on their sustainable design and operation for wastewater treatment. Firstly, a brief summary on the definition, classification and application of current CWs was presented. The design parameters and operational conditions of CWs including plant species, substrate types, water depth, hydraulic load, hydraulic retention time and feeding mode related to the sustainable operation for wastewater treatments were then discussed. Lastly, future research on improving the stability and sustainability of CWs were highlighted. PMID:25453440

Pervious pavements are sustainable urban drainage systems already known as rainwater infiltration techniques which reduce runoff formation and diffuse pollution in cities. The present research is focused on the design and construction of an experimental parking area, composed of 45 pervious pavement parking bays. Every pervious pavement was experimentally designed to store rainwater and measure the levels of the stored water and its quality over time. Six different pervious surfaces are combined with four different geotextiles in order to test which materials respond better to the good quality of rainwater storage over time and under the specific weather conditions of the north of Spain. The aim of this research was to obtain a good performance of pervious pavements that offered simultaneously a positive urban service and helped to harvest rainwater with a good quality to be used for non potable demands.

Design and construction of a large aperture quadrupole electromagnet for ILSE  

SciTech Connect

We are currently constructing a prototype quadrupole electromagnet for the proposed Induction Linac Systems Experiment (ILSE) at LBNL. ILSE will address many physics and engineering issues relevant to the design of a heavy-ion fusion driver accelerator. The pulsed electromagnet has two layers of current windings and will produce a field gradient of 28 T/m, wi a usable aperture of 6 cm. It operates at a repetition rate of 1 Hz, steady-state. In this paper, we discuss how the interaction of various concerns such as maximum dynamic aperture, short lattice period, field quality, iron yoke weight, heat transfer, and voltage standoff have led to our particular design choices. We also present 2- and 3-D numerical calculations concerning field topography and the results of transport simulations of space-charge dominated ion beams with ILSE parameters.

Global optimization based on metamodel construction app lied to design axial turbomachinery cascades using CFD  

NASA Astrophysics Data System (ADS)

It presents a methodology for global optimization with constraints of expensive functions using response surfaces models for aerodynamic cascade representing the turbomachine axial with profiles of family NACA65. For the calculation of flow, is used Fluent CFD software, which is on a local and global variations in the flow field. It has been verified that small geometric on the stagger angle, format airfoil and the spacing between the blades, can lead to changes in the efficiency of the blade. Accordingly, we intend to integrate the solution flow through CFD optimization programs based on the construction of metamodels, aiming to obtain considerable gains in computational time. Integration with the optimization programs is necessary to build "script" command to automatically generate the mesh, where the design variables that define the geometry of the blade cascade as stagger angle, pitch to chord and the camber be modified among pre-established limits based on optimization algorithms, in order to achieve an objective function pre-defined, how to obtain the maximum ratio of Cl/ Cd (lift/drag). This methodology for global optimization based on the construction of metamodels together with the random search algorithm controlled (CRSA) is based on iterative construction of response surfaces with radial basis functions (multiquadric) and the application of heuristic criteria to update the database during the optimization process. Cyclical patterns of search are iteratively used to determine the candidate points to be included in the database.

Advanced insulations for refrigerator/freezers: The potential for new shell designs incorporating polymer barrier construction  

SciTech Connect

The impending phase-out of chlorofluorocarbons (CFCs) used to expand foam insulation, combined with requirements for increased energy efficiency, make the use of non-CFC-based high performance insulation technologies increasingly attractive. The majority of current efforts are directed at using advanced insulations in the form of thin, flat low-conductivity gas-filled or evacuated orthogonal panels, which we refer to as Advanced Insulation Panels (AIPs). AIPs can be used in composite with blown polymer foams to improve insulation performance in refrigerator/freezers (R/Fs) of conventional design and manufacture. This AIP/foam composite approach is appealing because it appears to be a feasible, near-term method for incorporating advanced insulations into R/Fs without substantial redesign or retooling. However, the requirements for adequate flow of foam during the foam-in-place operation impose limitations on the allowable thickness and coverage area of AIPs. This report examines design alternatives which may offer a greater increase in overall thermal resistance than is possible with the use of AIP/foam composites in current R/F design. These design alternatives generally involve a basic redesign of the R/F taking into account the unique requirements of advanced insulations and the importance of minimizing thermal bridging with high thermal resistance insulations. The focus here is on R/F doors because they are relatively simple and independent R/F components and are therefore good candidates for development of alterative designs. R/F doors have significant thermal bridging problems due to the steel outer shell construction. A three dimensional finite difference computer modeling exercise of a R/F door geometry was used to compare the overall levels of thermal resistance (R-value) for various design configurations.

Factors influencing global antiretroviral procurement prices  

PubMed Central

Background Antiretroviral medicines (ARVs) are one of the most costly parts of HIV/AIDS treatment. Many countries are struggling to provide universal access to ARVs for all people living with HIV and AIDS. Although substantial price reductions of ARVs have occurred, especially between 2002 and 2008, achieving sustainable access for the next several decades remains a major challenge for most low- and middle-income countries. The objectives of the present study were twofold: first, to analyze global ARV prices between 2005 and 2008 and associated factors, particularly procurement methods and key donor policies on ARV procurement efficiency; second, to discuss the options of procurement processes and policies that should be considered when implementing or reforming access to ARV programs. Methods An ARV-medicines price-analysis was carried out using the Global Price Reporting Mechanism from the World Health Organization. For a selection of 12 ARVs, global median prices and price variation were calculated. Linear regression models for each ARV were used to identify factors that were associated with lower procurement prices. Logistic regression models were used to identify the characteristics of those countries which procure below the highest and lowest direct manufactured costs. Results Three key factors appear to have an influence on a country's ARV prices: (a) whether the product is generic or not; (b) the socioeconomic status of the country; (c) whether the country is a member of the Clinton HIV/AIDS Initiative. Factors which did not influence procurement below the highest direct manufactured costs were HIV prevalence, procurement volume, whether the country belongs to the least developed countries or a focus country of the United States President's Emergency Plan For AIDS Relief. Conclusion One of the principal mechanisms that can help to lower prices for ARV over the next several decades is increasing procurement efficiency. Benchmarking prices could be one useful tool to achieve this. PMID:19922690

Medical device procurement in low- and middle-income settings: protocol for a systematic review  

PubMed Central

Background Medical device procurement processes for low- and middle-income countries (LMICs) are a poorly understood and researched topic. To support LMIC policy formulation in this area, international public health organizations and research institutions issue a large body of predominantly grey literature including guidelines, manuals and recommendations. We propose to undertake a systematic review to identify and explore the medical device procurement methodologies suggested within this and further literature. Procurement facilitators and barriers will be identified, and methodologies for medical device prioritization under resource constraints will be discussed. Methods/design Searches of both bibliographic and grey literature will be conducted to identify documents relating to the procurement of medical devices in LMICs. Data will be extracted according to protocol on a number of pre-specified issues and variables. First, data relating to the specific settings described within the literature will be noted. Second, information relating to medical device procurement methodologies will be extracted, including prioritization of procurement under resource constraints, the use of evidence (e.g. cost-effectiveness evaluations, burden of disease data) as well as stakeholders participating in procurement processes. Information relating to prioritization methodologies will be extracted in the form of quotes or keywords, and analysis will include qualitative meta-summary. Narrative synthesis will be employed to analyse data otherwise extracted. The PRISMA guidelines for reporting will be followed. Discussion The current review will identify recommended medical device procurement methodologies for LMICs. Prioritization methods for medical device acquisition will be explored. Relevant stakeholders, facilitators and barriers will be discussed. The review is aimed at both LMIC decision makers and the international research community and hopes to offer a first holistic conceptualization of this topic. PMID:25336161

Status and Challenges of the LHC Construction  

E-print Network

The LHC is designed to provide proton beams of 7 TeV and nominal luminosity of 10**34 cm**-2s**-1. This objective is achieved at an affordable cost by pushing all major collider components to the limits of technology, by upgrading the existing CERN accelerators and infrastructure, and by involving the technical expertise, resources and dedication of accelerator laboratories world-wide. Following a decade of intensive R&D and technical validation of major collider systems, the LHC construction is now fully underway. Major industrial contracts have been awarded and are in execution for the procurement of the magnet, cryogenics and other systems. In this report, the status of the design and construction of the major LHC systems is presented.

Design and Construction of Field Reversed Configuration Plasma Chamber for Plasma Material Interaction Studies  

NASA Astrophysics Data System (ADS)

A Field Reversed Configuration (FRC) plasma source was designed and constructed to conduct high energy plasma-materials interaction studies. The purpose of these studies is the development of advanced materials for use in plasma based electric propulsion systems and nuclear fusion containment vessels. Outlined within this thesis is the basic concept of FRC plasmoid creation, an overview of the device design and integration of various diagnostics systems for plasma conditions and characterization, discussion on the variety of material defects resulting from the plasma exposure with methods and tools designed for characterization. Using a Michelson interferometer it was determined that the FRC plasma densities are on the order of ~1021 m-3. A novel dynamic pressure probe was created to measure ion velocities averaging 300 km/s. Compensating flux loop arrays were used to measure magnetic field strength and verify the existence of the FRC plasmoid and when used in combination with density measurements it was determined that the average ion temperatures are ~130 eV. X-ray Photoelectron Spectroscopy (XPS) was employed as a means of characterizing the size and shape of the plasma jet in the sample exposure positions. SEM results from preliminary studies reveal significant morphological changes on plasma facing material surfaces, and use of XRD to elucidate fuel gas-ion implantation strain rates correlated to plasma exposure energies.

Design and Construction of the NSTX Bakeout, Cooling and Vacuum Systems  

SciTech Connect

This paper will describe the design, construction and initial operation of the NSTX bakeout, water cooling and vacuum systems. The bakeout system is designed for two modes of operation. The first mode allows heating of the first wall components to 350 degrees C while the external vessel is cooled to 150 degrees C. The second mode cools the first wall to 150 degrees C and the external vessel to 50 degrees C. The system uses a low viscosity heat transfer oil which is capable of high temperature low pressure operation. The NSTX Torus Vacuum Pumping System (TVPS) is designed to achieve a base pressure of approximately 1x10 (superscript -8) Torr and to evacuate the plasma fuel gas loads in less than 5 minutes between discharges. The vacuum pumping system is capable of a pumping speed of approximately 3400 l/s for deuterium. The hardware consists of two turbo molecular pumps (TMPs) and a mechanical pump set consisting of a mechanical and a Roots blower pump. A PLC is used as the control system to provide remote monitoring, control and software interlock capability. The NSTX cooling water provides chilled, de ionized water for heat removal in the TF, OH and PF, power supplies, bus bar systems, and various diagnostics. The system provides flow monitoring via a PLC to prevent damage due to loss of flow.

Design and Construction of a Versatile Dual Volume Heteronuclear Double Resonance Microcoil NMR Probe  

PubMed Central

Improved NMR detection of mass limited samples can be obtained by taking advantage of the mass sensitivity of microcoil NMR, while throughput issues can be addressed using multiple, parallel sample detection coils. We present the design and construction of a double resonance 300-MHz dual volume microcoil NMR probe with thermally-etched 440-nL detection volumes and fused silica transfer lines for high-throughput stopped-flow or flow-through sample analysis. Two orthogonal solenoidal detection coils and the novel use of shielded inductors allowed the construction of a probe with negligible radio-frequency cross talk. The probe was resonated at 1H–2D (upper coil) and 1H–13C (lower coil) frequencies such that it could perform 1D and 2D experiments with active locking frequency. The coils exhibited line widths of 0.8 to 1.1 Hz with good mass sensitivity for both 1H and 13C NMR detection. 13C directly detected 2D HETCOR spectra of 5% v/v 13C labeled acetic acid were obtained in less than 5 min. Demonstration of the probe characteristics as well as applications of the versatile two-coil double resonance probe are discussed. PMID:19138541

Design Construction and Test Results of a HTS Solenoid For Energy Recovery Linac  

SciTech Connect

An innovative feature of the proposed Energy Recovery Linac (ERL) is the use of a solenoid made with High Temperature Superconductor (HTS) with the Superconducting RF cavity. The use of HTS allows solenoid to be placed in close proximity to the cavity and thus provides early focusing of the electron beam. In addition, cryogenic testing at {approx}77 K is simpler and cheaper than 4 K testing. This paper will present the design, construction and test results of this HTS solenoid. The HTS solenoid in the proposed ERL will be situated in the transition region between the superconducting cavity at {approx}4 K and the cryostat at the room temperature. Solenoid inside the cryogenic structure provides an early focusing and hence low emittance beam. The temperature in the transition region will be too high for a conventional low temperature superconductor and resistive heat load from copper coils will be too high on cryogenic system. HTS coils also allow much higher current density and significant reduction in size as compared to copper coils. Hence HTS solenoid provide a unique and technically superior solution. The use of a HTS solenoid with superconducting cavity offers a unique option as it can be placed in a cold to warm transition region to provide early focussing without using additional space. Construction and test results so far are very encouraging for its use in the ERL project.

A Filter-Mediated Communication Model for Design Collaboration in Building Construction  

PubMed Central

Multidisciplinary collaboration is an important aspect of modern engineering activities, arising from the growing complexity of artifacts whose design and construction require knowledge and skills that exceed the capacities of any one professional. However, current collaboration in the architecture, engineering, and construction industries often fails due to lack of shared understanding between different participants and limitations of their supporting tools. To achieve a high level of shared understanding, this study proposes a filter-mediated communication model. In the proposed model, participants retain their own data in the form most appropriate for their needs with domain-specific filters that transform the neutral representations into semantically rich ones, as needed by the participants. Conversely, the filters can translate semantically rich, domain-specific data into a neutral representation that can be accessed by other domain-specific filters. To validate the feasibility of the proposed model, we computationally implement the filter mechanism and apply it to a hypothetical test case. The result acknowledges that the filter mechanism can let the participants know ahead of time what will be the implications of their proposed actions, as seen from other participants' points of view.

Design, construction, and characterization of a set of biosensors for aromatic compounds.  

PubMed

Aromatic pollutants in the environments pose significant threat to human health due to their persistence and toxicity. Here, we report the design and comprehensive characterization of a set of aromatic biosensors constructed using green fluorescence protein as the reporter and aromatics-responsive transcriptional regulators, namely, NahR, XylS, HbpR, and DmpR, as the detectors. The genetic connections between the detectors and the reporter were carefully adjusted to achieve fold inductions far exceeding those reported in previous studies. For each biosensor, the functional characteristics including the dose-responses, dynamic range, and the detection spectrum of aromatic species were thoroughly measured. In particular, the interferences that nontypical inducers exert on each biosensor's response to its strongest inducer were evaluated. These well-characterized biosensors might serve as potent tools for environmental monitoring as well as quantitative gene regulation. PMID:25524112

(The design and construction of the proposed L* detector for the Superconducting Super Collider)  

SciTech Connect

Dr. William M. Bugg and a group from ORNL had very productive meetings with Professor Sam Ting and other members of the L3 collaboration. The L3 detector system, subsystems, and the associated support facilities were examined in some detail. Discussions were held with scientists involved in planning for the L* detector systems and members of the L3 staff interested in positions at ORNL/UTK. The trip was very successful. A collaborative arrangement was established for UTK and ORNL to become involved in the future design and construction of the L* detector. These include hosting the main meeting of the L* collaboration at ORNL to complete the Expression-of-Interest (EOI) proposal. Several prospective candidates were interviewed and collaborative interactions were started on some detector subsystems for L*.

Construction of a Single Beam Optical Trap with a Modified Design  

NASA Astrophysics Data System (ADS)

We have constructed an apparatus known as an optical tweezers using off the shelf, fairly inexpensive components. These include a 20 mw HeNe laser, a standard student lab optical microscope, and an inexpensive CCD firewire camera. The trap is designed to work with polystyrene spheres of various diameters, but to be robust enough for more advanced research. The goal of the work is to use the device for undergraduate research projects but also for use in the advanced labs at Angelo State. Trapping is achieved in the device by focusing the collimated laser beam using a 100x oil immersion objective on the microscope. At the position of the beam waist, the light produces gradient forces that trap the micron-sized spheres. Images are collected and processed using LabVIEW^TM software. Measurement of particle size is accomplished through software tools for use with unknown-sized samples in the future.

NASA Technical Reports Server (NTRS)

A paraboloid radio antenna of 10.4 meters diameter, 0.41 meter focal length was constructed and its successful completion is described. The surface accuracy of the antenna is at least four times better than any existing antenna in its class size (50 micrometers rms). Antenna design specifications (i.e., for mounting, drive motors, honeycomb structures) are discussed and engineering drawings and photographs of antenna components are shown. The antenna will be used for millimeter-wave interferometry and sub-millimeter wave radiometry over a full frequency range (up to approximately 860 GHz). The antenna will also be moveable (for interferometric use) between reinforced concrete pads by rail. The effects of the weather and gravity on antenna performance are briefly discussed.

The design and construction of a hot dry rock pilot plant  

SciTech Connect

The geothermal energy program at the Los Alamos National Laboratory is directed toward demonstrating the potential of the hot dry rock (HDR) technology as an alternate energy source. Since the inception of the program, scientists and engineers have perfected drilling and fracturing techniques to create underground reservoirs for the purpose of tapping the potential heat energy from the hot rock in the earth. One of the achievements to date has been the creation of a reservoir at the Laboratory's test site at Fenton Hill, New Mexico. This reservoir, located at a depth of 12,000 feet below the surface of the earth, has an estimated fluid capacity of one million gallons within the large volume of fractured rock. To evaluate the thermal power potential of this reservoir, preparations are currently underway to conduct a test which will entail the circulation of fluid through the reservoir by the injection of water at high pressures. A major part of the preparations involves the building of a demonstration pilot plant. The process concept poses a number of unique technical challenges with regard to the design and construction of the equipment and facilities. This paper reviews the system design and operating features of this plant. 3 refs., 4 figs.

Design and construction of a thermophotovoltaic generator using turbine combustion gas  

SciTech Connect

This US Naval Academy project involves the development of a prototype thermophotovoltaic (TPV) generator that uses a General Electric T-58 helicopter gas turbine as the heat source. The goals of this project were to demonstrate the viability of using TPV and external combustion gases to generate electricity, and develop a system which could also be used for materials testing. The generator was modularly designed so that different materials could be tested at a later date. The combustion gas was tapped from the T-58`s combustor through one of the two igniter ports and extracted through a silicon carbide matrix ceramic composite tube into a similarly constructed ceramic composite radiant emitter. The ceramic radiant emitters is heated by the combustion gas via convection, and then serves the TPV generator by radiating the heat outwards where it can be absorbed by thermophotovoltaic cells and converted directly into electricity. The gas turbine and generator module are monitored by a data acquisition system that performs both data collection and control functions. This paper details the design of the TPV generator. It also gives results of initial tests with the gas turbine.

Design consideration in constructing high performance embedded Knowledge-Based Systems (KBS)  

NASA Technical Reports Server (NTRS)

As the hardware trends for artificial intelligence (AI) involve more and more complexity, the process of optimizing the computer system design for a particular problem will also increase in complexity. Space applications of knowledge based systems (KBS) will often require an ability to perform both numerically intensive vector computations and real time symbolic computations. Although parallel machines can theoretically achieve the speeds necessary for most of these problems, if the application itself is not highly parallel, the machine's power cannot be utilized. A scheme is presented which will provide the computer systems engineer with a tool for analyzing machines with various configurations of array, symbolic, scaler, and multiprocessors. High speed networks and interconnections make customized, distributed, intelligent systems feasible for the application of AI in space. The method presented can be used to optimize such AI system configurations and to make comparisons between existing computer systems. It is an open question whether or not, for a given mission requirement, a suitable computer system design can be constructed for any amount of money.

A Systems Engineering Framework for Design, Construction and Operation of the Next Generation Nuclear Plant  

SciTech Connect

Not since the International Space Station has a project of such wide participation been proposed for the United States. Ten countries, the European Union, universities, Department of Energy (DOE) laboratories, and industry will participate in the research and development, design, construction and/or operation of the fourth generation of nuclear power plants with a demonstration reactor to be built at a DOE site and operational by the middle of the next decade. This reactor will be like no other. The Next Generation Nuclear Plant (NGNP) will be passively safe, economical, highly efficient, modular, proliferation resistant, and sustainable. In addition to electrical generation, the NGNP will demonstrate efficient and cost effective generation of hydrogen to support the President’s Hydrogen Initiative. To effectively manage this multi-organizational and technologically complex project, systems engineering techniques and processes will be used extensively to ensure delivery of the final product. The technological and organizational challenges are complex. Research and development activities are required, material standards require development, hydrogen production, storage and infrastructure requirements are not well developed, and the Nuclear Regulatory Commission may further define risk-informed/performance-based approach to licensing. Detailed design and development will be challenged by the vast cultural and institutional differences across the participants. Systems engineering processes must bring the technological and organizational complexity together to ensure successful product delivery. This paper will define the framework for application of systems engineering to this $1.5B - $1.9B project.

Winchester/Camberley Homes New Construction Test House Design, Construction, and Short-Term Testing in a Mixed-Humid Climate  

SciTech Connect

The NAHB Research Center partnered with production builder Winchester/Camberley Homes to build a DOE Building America New Construction Test House (NCTH). This single family, detached house, located in the mixed-humid climate zone of Silver Spring, MD, was completed in June 2011. The primary goal for this house was to improve energy efficiency by 30% over the Building America B10 benchmark by developing and implementing an optimized energy solutions package design that could be cost effectively and reliably constructed on a production basis using quality management practices. The intent of this report is to outline the features of this house, discuss the implementation of the energy efficient design, and report on short-term testing results. During the interactive design process of this project, numerous iterations of the framing, air sealing, insulation, and space conditioning systems were evaluated for energy performance, cost, and practical implementation. The final design featured numerous advanced framing techniques, high levels of insulation, and the HVAC system entirely within conditioned space. Short-term testing confirmed a very tight thermal envelope and efficient and effective heating and cooling. In addition, relevant heating, cooling, humidity, energy, and wall cavity moisture data will be collected and presented in a future long-term report.

Design and Construct an Optical Device to Determine Relative Blood Volume in Patients Undergoing Hemodialysis  

PubMed Central

Background: Occurrence of hypotension during hemodialysis in nearly 20-30% of patients, shows is the necessity of continuous monitoring the patients' blood pressure during hemodialysis. Since directly and non-invasively continuous blood pressure monitoring, is not easy, finding a parameter related to blood pressure, for indirect monitoring is of great value. Related blood volume (RBV) is one of the parameters, related to blood pressure and have a good potential to reflect the patient’s hemodynamic condition. Objectives: The main objective of this study was to design and construct an optical device to determine the RBV in patients undergoing hemodialysis, during the process. Materials and Methods: After initial studies in order to select a proper sensor, using the ORCAD software, an analog circuit was designed. The implementation and modification of the circuit was done by the clinical tests, using expired blood. Afterwards, for calculation the RBV, controlling the display, data storage and sending it to the computer, an ATmega16 microcontroller was used. For programing the microcontroller, CodeVision software and then Altium Designer software were used for the circuit compression, in order to design the printed circuit board. Finally, all parts of the analog and digital circuit, AC to DC converter and the LCD were embedded in a box. Results: After finalization of the device and before testing it in a real situation, expired blood was used for final evaluation. The evaluation was done by changing the blood concentration, at the start point by adding water to it. In fact, the device can track the changes in blood concentration and display the RBV. After this evaluation, the device was tested in a clinical situation. The results showed there are no interactions between this device and the other devices used in the dialysis section and it can work properly in order to measure the RBV. Conclusions: Considering the hypotension and its consequences in a patient on hemodialysis, solving this problem seems necessary. One method for preventing this, is to use the blood pressure related parameters and one of these parameters is the RBV. In this study, in order to measure the RBV, a device was designed and evaluated by expired blood and also tested in a clinical situation. Results showed that the device could work properly in order to measure the RBV. PMID:24910804

Review of the Design, Construction, and Coming Scientific Capabilities of the New Arecibo HF Facility  

NASA Astrophysics Data System (ADS)

The design of the new Arecibo HF facility gives efficient illumination of the 305 meter dish without compromising the use of other feeds. When complete, it will provide 83 dbW at 8.175 MHz, and 80 dbW at 5.1 MHz. Illumination of the 305 meter dish uses dipoles near the surface of the dish transmitting upward to a sub-reflector that illuminates the main dish. There are three crossed dipoles for each of the two frequencies. Each dipole section is fed from one of six 100KW transmitters The sub-reflector will consist of a metal mesh with five foot openings, shaped approximately as a catenary rotated about a vertical axis, but actually hexagonal rather than circular at the top. It is held by cables from the three main towers. The dipoles will be supported on towers mounted on concrete pads underneath the dish. The dipole elements can be stowed along the tower sides between operational campaigns. The six towers, three for each frequency, pass through the surface of the dish, requiring the removal of two panels for each. Each dipole element is connected to a transmitter through a three inch coax line. The six transmitters are located in a steel building located several hundred feet from the 305 meter dish. The electrical substation that provides power to the transmitters and the heat exchangers which provide cooling are located outside this building. At this time, the six transmitters in the building are ready for the final wiring. The duct work for the air cooling is complete the the blowers are installed. The pipes for the water cooling are in place and connection to the pump located with the heat exchangers is underway. The trays for the coax lines have been installed from the transmitter building to underneath the dish. One line has been installed in order to verify that this can be done easily. The others will be installed when the civil work underneath the dish is complete. Four one MW generators are on site and being installed. These will provide a flexible and complete power system for planetary radar, the HF facility, and site backup. Design of the mesh is complete and the construction phase has started. One of the tower base concrete pads will sit on ground that is softer than expected and this pad is being designed by the engineering firm Amman and Whitney. The other five use the standard design provided by the tower manufacturer. Amman and Whitney are also reviewing the mesh support design and have recommended some changes in the cable support system in order to provide better temperature stability. As the project construction is completed in the next few months, we face the problems of producing a practical scientific facility. This facility is inherently a lot less complicated than the HAARP facility in Alaska. Nonetheless, a computer control and monitoring system is very desirable, both to allow the most complete control over the transmitted waveforms, and to allow the highest reliability of operation. We are currently reviewing the best ways to accomplish this. We expect that a basic system will be in place for the first couple of operational campaigns, with full flexibility coming later. The basic operation would be similar to our previous facility at Islote, vertical operation with continuous wave or a simple pulse sequence on a single frequency.

Performance of a continuous flow ventricular assist device: magnetic bearing design, construction, and testing.  

PubMed

A new centrifugal continuous flow ventricular assist device, the CFVAD III, which is fully magnetic bearing suspended, has been developed. It has only one moving part (the impeller), has no contact (magnetic suspension), is compact, and has minimal heating. A centrifugal impeller of 2 inch outer diameter is driven by a permanent magnet brushless DC motor. This paper discusses the design, construction, testing, and performance of the magnetic bearings in the unit. The magnetic suspension consists of an inlet side magnetic bearing and an outlet side magnetic bearing, each divided into 8 pole segments to control axial and radial displacements as well as angular displacements. The magnetic actuators are composed of several different materials to minimize size and weight while having sufficient load capacity to support the forces on the impeller. Flux levels in the range of 0.1 T are employed in the magnetic bearings. Self sensing electronic circuits (without physical sensors) are employed to determine the impellar position and provide the feedback control signal needed for the magnetic bearing control loops. The sensors provide position sensitivity of approximately 0.025 mm. A decentralized 5 axis controller has been developed using modal control techniques. Proportional integral derivative controls are used for each axis to levitate the magnetically supported impeller. PMID:9650668

Design and construction of a naïve mouse antibody phage display library.  

PubMed

Antibody phage technology has greatly facilitated the isolation of good-quality monoclonal antibodies to virtually any target antigen. Large combinatorial phage display libraries of human antibodies are routinely being used for the identification of antibody candidates for clinical applications. However, preclinical studies in rodents would benefit from the availability of good-quality single-pot mouse antibody libraries, which at present are not available. In this article, we report on the construction of three mouse antibody phage display libraries, all containing over 1 billion antibody clones and all based on a similar library design, which featured the combinatorial mutagenesis of residues in the CDR3 loops of a given antibody scaffold. While all three libraries were found to express antibodies in bacterial supernatants, only one of them (termed "PHILOtop") was shown to reliably yield good-quality antibodies towards all protein antigens used so far in selection experiments, including three tumor-associated antigens. The modular structure of the PHILOtop library facilitates a simple affinity-maturation procedure based on the combinatorial mutagenesis of CDR1 and CDR2 loops of the VH domain, which has led to the isolation of a high-affinity antibody ("H7"; Kd=6 nM) specific to the EDB domain of fibronectin, a marker of angiogenesis. The single-pot antibody library PHILOtop may thus represent a useful source of binding specificities, facilitating preclinical studies in immunocompetent syngeneic mouse models of pathology.

Design and construction of the NMSU Geothermally Heated Greenhouse Research Facility: Final technical report  

SciTech Connect

This report describes the design, construction, and performance of the New Mexico State University (NMSU) Geothermal Greenhouse Research Facility. Two 6000-square-foot greenhouses were built on the NMSU campus and supplied with geothermal energy for heating. The geothermal water is pumped from one of three wells producing water at temperatures from 141/degree/F to 148/degree/F. Heat is delivered to the greenhouse space by means of overhead fan-coil unit heaters. The two greenhouses are double-glazed on roof and wall surfaces employing a total of four different film materials: Tedlar/Reg Sign/, Melinex/Reg Sign/, Softglass/Reg Sign/, and Agrifilm/Reg Sign/. One greenhouse is cooled using a traditional fan and pad cooling system. The second greenhouse is cooled with a high-pressure fog system and natural ventilation through roof and side vents. A 2400-square-foot metal building next to the greenhouses provides office, work, and storage space for the facility. The greenhouse facility was leased to two commerical tenants who produced a variety of crops. The performance of the greenhouses was monitored and reported both qualitatively and quantitatively. Results from the tenant's pilot-scale studies in the NMSU greenhouse facility were transferred and applied to two commercial greenhouse ranges that were built in southern New Mexico during 1986/87. 9 figs., 5 tabs.

Affordable housing through energy conservation: A guide to designing and constructing energy efficient homes  

SciTech Connect

PEAR is an interactive program for residential building energy analysis utilizing a comprehensive DOE-2.1 data base for residential buildings. This data base was compiled using over 10,000 computer simulations covering five residential buildings in 45 geographical locations. This extensive data base is used by PEAR to estimate the annual energy use of houses with typical conservation measures such as ceiling, wall, and floor insulation, different window types and glazing layers, infiltration levels, and equipment efficiency. It also allows the user to include the effects of roof and wall color, movable night insulation on the windows, reflective and heat absorbing glass, an attached sunspace, and use of a night setback. Regression techniques in PEAR permit adjustments for different building geometries, window areas and orientations, wall construction, and extension of the data to over 800 US locations based on climate parameters. PEAR is designed as a user-friendly program that can be used both as a research tool by energy policy analysts, and as a nontechnical energy calculation method by architects, homebuilders, homeowners, and others in the building industry. Technical documentation of the PEAR program and the database is given elsewhere (see References). 3 refs., 11 figs., 5 tabs.

Based on a design similar to that of CsV, the 2.1 m NRC primary cesium clock, they have bi-directional beam capability, a resonance line width of about 100 Hz, and embody improvements to the cesium ovens, detectors, and dipole magnetic-state selectors which lead to a lifetime, estimated from cesium consumption, of about 25 years. In operation as secondary clocks from late 1978 until December 1979, and subsequently as primary clocks, they provide an accuracy and stability comparable to those of CsV. Long-term frequency stability is better than 1 × 10-14, and short-term frequency stability at beam currents normally used for continuous clock operation of about 2.5 to 3 pA is about 1 × 10-13 for 1000 s averaging time. The limit of error, estimated from two complete accuracy evaluations, one performed in late 1979 and the second early in 1981, is about 1.5 × 10-13. The frequencies of the three clocks, CsVIA, CsVIB, and CsVIC, remained within 2 × 10-13 of that of CsV during their first year and a half of operation as primary clocks, and within 5 × 10-14 during the final part of this period subsequent to a number of improvements made to certain of the electronics systems.

Design and construction of a Fourier transform soft x-ray interferometer  

SciTech Connect

Helium, with its two electrons and one nucleus, is a three-body system. One of the models for investigating correlated electron motion in this system is autoionization, produced via double excitation of the electrons. Predictions about the autoionization spectrum of helium have differed from each other and from preliminary experimental data. However, previous experiments have not been able to distinguish among the theoretical predictions because their energy resolution is not high enough to resolve the narrow linewidths of quasi-forbidden peaks and the resonances that appear in the highest excited states. Consequently, a team of researchers at Lawrence Berkeley National Laboratory have embarked on a project for building a high-resolution Fourier-Transform Soft X-ray (or VUV) interferometer (FTSX) to provide definitive data to answer remaining questions about the autoionization spectrum of helium. The design and construction of this interferometer is described in detail below, including the use of a flexure stage to provide the large path length difference necessary for high resolution measurements, the manufacture of x-ray beamsplitters, a description of the software, and the solution to the problems of stick-slip, vibration, and alignment. Current progress of its development is also described, as well as future goals.

Design, construction and tests of a 3 GHz proton linac booster (LIBO) for cancer therapy  

NASA Astrophysics Data System (ADS)

In the last ten years the use of proton beams in radiation therapy has become a clinical tool for treatment of deep-seated tumours. LIBO is a RF compact and low cost proton linear accelerator (SCL type) for hadrontherapy. It is conceived by TERA Foundation as a 3 GHz Linac Booster, to be mounted downstream of an existing cyclotron in order to boost the energy of the proton beam up to 200 MeV, needed for deep treatment (~25 cm) in the human body. With this solution it is possible to transform a low energy commercial cyclotron, normally used for eye melanoma therapy, isotope production and nuclear physics research, into an accelerator for deep-seated tumours. A prototype module of LIBO has been built and successfully tested with full RF power at CERN and with proton beam at INFN Laboratori Nazionali del Sud (LNS) in Catania, within an international collaboration between TERA Foundation, CERN, the Universities and INFN groups of Milan and Naples. The mid-term aim of the project is the technology transfer of the accumulated know-how to a consortium of companies and to bring this novel medical tool to hospitals. The design, construction and tests of the LIBO prototype are described in detail.

Studies on questions of design and construction of chain scraper conveyors. [mining operations  

NASA Technical Reports Server (NTRS)

The basic behavior of mining crushed goods in chain scraper conveyors was examined using a special test stand. The characteristics resistance lines of the upper end-piece were determined for conveyor idle as a function of the determinative crushed good characteristics (granular structure, moisture content, type of goods) on the size of the conveyor load, on the conveyor construction and on the stopped time of the conveyor. Crushed goods with a narrow granular profile and sphere-like grains caused about 35% greater resistance than fine coal and raw coal with broad granular profile. For goods containing water more than 10% by weight, the solids friction retreated in favor of flow friction. The coefficient of resistance decreased considerably in the range of lower speeds and then increased with increasing conveyor speed. The conveyance of sandstone ore required about 280% greater specific drive than the conveyance of raw coal. Resistance coefficients for coal and raw coal showed no dependence on the design of the conveyor. Start-up of loaded conveyors after longer stop times was simulated and the specific break-loose force was determined.

Construction of a Single Beam Optical Trap with a Modified Design for Undergraduate Labs  

NASA Astrophysics Data System (ADS)

We have constructed an apparatus known as an optical tweezers using off the shelf, fairly inexpensive components. These include a 20 mw HeNe laser, a standard student lab optical microscope, and an inexpensive CCD firewire camera. The trap is designed to work with polystyrene spheres of various diameters, but to be robust enough for more advanced research. The goal of the work is to use the device for undergraduate research projects but also for use in the advanced labs at Angelo State University. Trapping is achieved in the device by focusing the collimated laser beam using a 100x oil immersion objective on the microscope. At the position of the beam waist, the light produces gradient forces that trap the micron-sized spheres. Images are collected and processed using LabVIEW software and measurement of particle size is accomplished through software tools for use with unknown-sized samples. Currently, imaging tests are being performed to improve the focus of the camera on the trapping region. It is expected that successful trapping of the polystyrene spheres will soon be accomplished. Once that is established then we will trap birefringent particles such as quartz or calcite. Birefringent particles should exhibit rotational motion when trapped.

Design and construction of a 1 m model of the low current superconducting quadrupole for the LHC insertions  

E-print Network

About one hundred individually powered low current superconducting quadrupoles will be installed in the LHC insertions. One of the design requirements was to keep the excitation current of the magnet below 6 kA in view of minimizing the costs of the powering circuits. The design of the quadrupole is based on a 8.2 mm NbTi cable, and is designed for a nominal gradient of 200 T/m at 1.9 K. In this paper we present the design of the quadrupole and discuss the construction details of the 1 m single aperture model which has been recently completed.

Design, construction, and evaluation of new high resolution medical imaging detector/systems  

NASA Astrophysics Data System (ADS)

Increasing need of minimally invasive endovascular image guided interventional procedures (EIGI) for accurate and successful treatment of vascular disease has set a quest for better image quality. Current state of the art detectors are not up to the mark for these complex procedures due to their inherent limitations. Our group has been actively working on the design and construction of a high resolution, region of interest CCD-based X-ray imager for some time. As a part of that endeavor, a Micro-angiographic fluoroscope (MAF) was developed to serve as a high resolution, ROI X-ray imaging detector in conjunction with large lower resolution full field of view (FOV) state-of-the-art x-ray detectors. The newly developed MAF is an indirect x-ray imaging detector capable of providing real-time images with high resolution, high sensitivity, no lag and low instrumentation noise. It consists of a CCD camera coupled to a light image intensifier (LII) through a fiber optic taper. The CsI(Tl) phosphor serving as the front end is coupled to the LII. For this work, the MAF was designed and constructed. The linear system cascade theory was used to evaluate the performance theoretically. Linear system metrics such as MTF and DQE were used to gauge the detector performance experimentally. The capabilities of the MAF as a complete system were tested using generalized linear system metrics. With generalized linear system metrics the effects of finite size focal spot, geometric magnification and the presence of scatter are included in the analysis and study. To minimize the effect of scatter, an anti-scatter grid specially designed for the MAF was also studied. The MAF was compared with the flat panel detector using signal-to-noise ratio and the two dimensional linear system metrics. The signal-to-noise comparison was carried out to point out the effect of pixel size and Point Spread Function of the detector. The two dimensional linear system metrics were used to investigate the comparative performance of both the detectors in similar simulated clinical neuro-vascular conditions. The last part of this work presents a unique quality of the MAF: operation in single photon mode. The successful operation of the MAF was demonstrated with considerable improvement in spatial and contrast resolution over conventional energy integrating mode. The work presented shows the evolution of a high resolution, high sensitivity, and region of interest x-ray imaging detector as an attractive and capable x-ray imager for the betterment of complex EIGI procedures. The capability of single photon counting mode imaging provides the potential for additional uses of the MAF including the possibility of use in dual modality imaging with radionuclide sources as well as x-rays.

Design and Use of Interactive Learning Stations in Construction Education for Building Mechanical, Electrical, and Plumbing Systems  

NSDL National Science Digital Library

Over the past several years, the building codes that govern the design and installation of mechanical and electrical systems for buildings have become increasingly prescriptive in nature, specifying detailed information related to the design and installation of the systems, while offering no reasoning behind their prescriptive measures. Students now read about the design and installation of these systems in textbooks, and using the building codes, have in-class exercises drafting the systems, which in industry are used for fabrication and installation. Therefore, in conjunction with a new curriculum proposed for the construction management department at California Polytechnic State University (Cal Poly), San Luis Obispo an interactive learning station was developed for student use to enhance student learning. This paper focuses on the design and use of interactive learning stations for building mechanical, electrical, and plumbing (MEP) systems that allow construction students to perform hands-on fit-up exercises and test their performance.

Antiretroviral procurement and supply chain management.  

PubMed

Procurement, the country-level process of ordering antiretrovirals (ARVs), and supply chain management, the mechanism by which they are delivered to health-care facilities, are critical processes required to move ARVs from manufacturers to patients. To provide a glimpse into the ARV procurement and supply chain, the following pages provide an overview of the primary stakeholders, principal operating models, and policies and regulations involved in ARV procurement. Also presented are key challenges that need to be addressed to ensure that the supply chain is not a barrier to the goal of universal coverage. This article will cover the steps necessary to order and distribute ARVs, including different models of delivery, key stakeholders involved, strategic considerations that vary depending on context and policies affecting them. The single drug examples given illustrate the complications inherent in fragmented supply and demand-driven models of procurement and supply chain management, and suggest tools for navigating these hurdles that will ultimately result in more secure and reliable ARV provision. Understanding the dynamics of ARV supply chain is important for the global health community, both to ensure full and efficient treatment of persons living with HIV as well as to inform the supply chain decisions for other public health products.

Duct Remediation Program: Engineered access research and construction  

SciTech Connect

The Rocky Flats Plant, Duct Remediation mission concentrated on removing Plutonium Oxide from the process ductwork in the primary Plutonium processing facility. When possible, remediation took place from existing process gloveboxes. Fifteen locations were identified, however, that required accessing duct runs where no process gloveboxes existed. The building`s second floor utility areas had many locations where long, inaccessible duct runs were prevalent. Consequently, an extensive program for design, procurement and construction was initiated to contain and isolate ducts for penetration when existing glovebox sites were not present.
