Human portable preconcentrator system  

DOE Patents (OSTI)

A preconcentrator system and apparatus suited to human portable use wherein sample potentially containing a target chemical substance is drawn into a chamber and through a pervious screen. The screen is adapted to capture target chemicals and then, upon heating, to release those chemicals into the chamber. Chemicals captured and then released in this fashion are then carried to a portable chemical detection device such as a portable ion mobility spectrometer. In the preferred embodiment, the means for drawing sample into the chamber comprises a reversible fan which, when operated in reverse direction, creates a backpressure that facilitates evolution of captured target chemicals into the chamber when the screen is heated.

Portable treatment systems study  

SciTech Connect

In developing their Site Treatment Plans (STPs), many of the Department of Energy installations identified some form of portable treatment, to facilitate compliant disposition of select mixed low-level wastestreams. The Environmental Management Office of Science and Technology requested that a systems study be performed to better define the potential role of portable treatment with respect to mixed low-level waste, highlight obstacles to implementation, and identify opportunities for future research and development emphasis. The study was performed by first establishing a representative set of mixed waste, then formulating portable treatment system concepts to meet the required processing needs for these wastes. The portable systems that were conceptualized were evaluated and compared to a fixed centralized treatment alternative. The system evaluations include a life-cycle cost analysis and an assessment of regulatory, institutional, and technical issues associated with the potential use of portable systems. The results of this study show that when all costs are included, there are no significant cost differences between portable systems and fixed systems. However, it is also emphasized that many uncertainties exist that could impact the cost of implementing portable treatment systems. Portable treatment could be made more attractive through private sector implementation, although there is little economic incentive for a commercial vendor to develop small, specialized treatment capabilities with limited applicability. Alternatively, there may also be valid reasons why fixed units cannot be used for some problematic wastestreams. In any event, there are some site-specific problems that still need to be addressed, and there may be some opportunity for research and development to make a positive impact in these areas.

Portable deaerator for deionized water systems  

Science Conference Proceedings (OSTI)

The flowing water deaerator systems were designed and built for the TEMPO microwave pulser. The TEMPO program major goals were to build three one-megavolt, rep-rate pulsers capable of providing high power pulsed microwaves for various susceptibility and biological experiments. The TEMPO machine is a transformer driven water dielectric transmission line pulser. The water in the transmission line is required to have high purity and be bubble-free. The purity of the water is maintained by a filtered deionizing system that was supplied by a local vendor. The deaerating system was unique because it was required to be portable and self-contained. The design was based on a very large existing system (RADLAC II) which was not portable. The present system was scaled down to the approximate size of 2 ft x 4 ft x 7 ft high and mounted on a caster-supported frame for portability. Its small size and closed-loop operation allowed it to fit into a transportable subsystem container which housed the water processing and air supply systems. The following report discusses the design, installation, and operation of this flowing water deaerator.

Portable, remote environmental control system  

Science Conference Proceedings (OSTI)

A portable thermostat is coupled to the control unit of a heating or cooling device through a radio link. The RF signal transmitted by the thermostat is encoded and then decoded by the control unit in order to prevent interference with other similar devices. In order to maximize the life of a battery powering the thermostat, the thermostat calls for the energization of a heating or cooling device by transmitting the RF signal at widely spaced intervals. The heating or cooling device is energized by shunting a pair of terminals, thereby completing an AC control loop. The unit applies the terminals to a storage copacitor during a small portion of each EC cycle to power the control unit while shunting the terminals during the remaining part of the cycle.

Compact portable electric power sources  

DOE Green Energy (OSTI)

This report provides an overview of recent advances in portable electric power source (PEPS) technology and an assessment of emerging PEPS technologies that may meet US Special Operations Command`s (SOCOM) needs in the next 1--2- and 3--5-year time frames. The assessment was performed through a literature search and interviews with experts in various laboratories and companies. Nineteen PEPS technologies were reviewed and characterized as (1) PEPSs that meet SOCOM requirements; (2) PEPSs that could fulfill requirements for special field conditions and locations; (3) potentially high-payoff sources that require additional R and D; and (4) sources unlikely to meet present SOCOM requirements. 6 figs., 10 tabs.

Characterizing solar mirror materials using portable reflectometers  

DOE Green Energy (OSTI)

Currently available portable instrumentation for hemispherical and specular reflectance measurements of solar mirror materials is discussed. Particular attention is given to the wavelength dependence of the measurement spectrum, which in most cases does not approximate a solar spectral distribution, and to other limitations of each instrument. Because a portable instrument is not available that can determine the solar averaged specular reflectance from a single measurement, two procedures are recommended for obtaining a reasonable estimate for this quantity using the existing portable equipment. Finally, future developments in this area are briefly discussed.

Portable Classroom Research Project Highlights Energy Efficiency  

Science Conference Proceedings (OSTI)

Sixty-five percent of schools in the West report using portable classrooms and use of portables is growing every year. In the Northwest, the US Department of Energy’s Building America Industrialized Housing Partnership is exploring ways of making portable classrooms more efficient and better for learning. The Northwest state energy offices and Pacific Northwest National Laboratory, (PNNL) are using building science to examine energy consumption, lighting and ventilation to make these classrooms more comfortable and better value investments. This article describes evaluations of new and retrofit portables and recommendations for improved energy efficiency. Preliminary findings indicate that simple, low cost measures can do much to reduce energy costs and increase efficiency.

Direct methanol fuel cells: Developments for portable power and for potential transportation applications  

DOE Green Energy (OSTI)

The authors describe here results of recent efforts at Los Alamos National Laboratory (LANL), devoted to potential application of Direct Methanol Fuel Cells (DMFCs) as (1) portable power sources at the 50 W level, and (2) primary power sources for electric vehicles. In general, DMFC R and D efforts focus on further improvements in anode catalytic activity, fuel utilization (as related to methanol crossover) and air cathode performance in the presence of the presence of the significant flux of aqueous methanol from anode to cathode. There are significant differences between technical parameters and targets for the two different DMFC applications, which the authors have addressed. They include the lower cell temperature (about 60 C) preferred in portable power vs. operation around 100 C as target temperature for transportation applications, and the much stronger concern for cost of catalyst and any other stack materials in DMFCs developed for potential transportation applications. Most, if not all, recent DMFC work for either portable power or potential transportation applications has strongly focused on cells with polymeric (primarily PFSA) membrane electrolytes. In work at LANL, thin film catalysts bonded to the membrane, e.g., by the decal method, provided best results in terms of catalyst utilization and overall cell performance. In most tests, the single DMFC hardware consisted of uncatalyzed carbon-cloth gas-diffusion backings and graphite blocks with machined serpentine flow channels--quite similar to hardware employed in work with hydrogen/air PEFCs. However, the machined graphite hardware has recently been replaced by alternative, non-machined flow-field/bipolar plates, which enables effective air and aqueous methanol solution distribution along an active area of 50 cm{sup 2}, at a pitch per cell of 2 mm.

ASC legacy software must be ported to emerging hardware architectures. This paper notes that many programming models used by DOE applications are similar, and suggests that constructing a common terminology across these models could reveal a performance portable programming model. The paper then highlights how the LULESH mini-app is used to explore new programming models with outside solution providers. Finally, we suggest better tools to identify parallelism in software, and give suggestions for enhancing the co-design process with vendors.

Portable top drive cuts horizontal drilling costs  

SciTech Connect

Economic analysis of a seven-well, long-reach horizontal drilling program into an unconsolidated, heavy-oil-bearing reservoir in Winter field near the Alberta/Saskatchewan border in Canada reveals that -- in the right application -- renting a portable top drive drilling system can reduce total drilling costs. Use of the portable top drive combined with other cost-saving measures enabled Saskoil, one of Canada`s larger independents, to drill more cheaply, on a cost-per-meter basis, in 1993 than in 1992. This was despite significant rental rates for drilling rigs and directional drilling services caused by increased demand in Western Canada. Total cost savings of 10% on wells that would otherwise cost in the (C) $500,000 range are believed realistic. Based on this year`s performance, Saskoil recommends top drive for the company`s future horizontal wells in this area. This article describes the operator`s horizontal well program, advantages of top drive in that program and how it was installed and applied. Estimated time savings for six wells, plus other ways top drive can cut costs and improve operations are discussed.

Stirling machine operating experience  

Science Conference Proceedings (OSTI)

Numerous Stirling machines have been built and operated, but the operating experience of these machines is not well known. It is important to examine this operating experience in detail, because it largely substantiates the claim that stirling machines are capable of reliable and lengthy operating lives. The amount of data that exists is impressive, considering that many of the machines that have been built are developmental machines intended to show proof of concept, and are not expected to operate for lengthy periods of time. Some Stirling machines (typically free-piston machines) achieve long life through non-contact bearings, while other Stirling machines (typically kinematic) have achieved long operating lives through regular seal and bearing replacements. In addition to engine and system testing, life testing of critical components is also considered. The record in this paper is not complete, due to the reluctance of some organizations to release operational data and because several organizations were not contacted. The authors intend to repeat this assessment in three years, hoping for even greater participation.

These guidelines apply to all use of hand tools and portable power tools by CAT/XSD personnel while performing maintenance or installation activities at the APS. Although CAT/XSD feels that most of the guidelines also apply to tool usage during experimental activities, CAT/XSD will not require that short-term users complete the training described below.

Portable thermo-photovoltaic power source  

DOE Patents (OSTI)

A miniature thermo-photovoltaic (TPV) device for generation of electrical power for use in portable electronic devices. A TPV power source is constructed to provide a heat source chemical reactor capable of using various fuels, such as liquid hydrocarbons, including but not limited to propane, LPG, butane, alcohols, oils and diesel fuels to generate a source of photons. A reflector dish guides misdirected photon energy from the photon source toward a photovoltaic array. A thin transparent protector sheet is disposed between the photon source and the array to reflect back thermal energy that cannot be converted to electricity, and protect the array from thermal damage. A microlens disposed between the protector sheet and the array further focuses the tailored band of photon energy from the photon source onto an array of photovoltaic cells, whereby the photon energy is converted to electrical power. A heat recuperator removes thermal energy from reactor chamber exhaust gases, preferably using mini- or micro-bellows to force air and fuel past the exhaust gases, and uses the energy to preheat the fuel and oxidant before it reaches the reactor, increasing system efficiency. Mini- or micro-bellows force ambient air through the system both to supply oxidant and to provide cooling. Finally, an insulator, which is preferably a super insulator, is disposed around the TPV power source to reduce fuel consumption, and to keep the TPV power source cool to the touch so it can be used in hand-held devices.

Laser machining of explosives  

DOE Patents (OSTI)

The invention consists of a method for machining (cutting, drilling, sculpting) of explosives (e.g., TNT, TATB, PETN, RDX, etc.). By using pulses of a duration in the range of 5 femtoseconds to 50 picoseconds, extremely precise and rapid machining can be achieved with essentially no heat or shock affected zone. In this method, material is removed by a nonthermal mechanism. A combination of multiphoton and collisional ionization creates a critical density plasma in a time scale much shorter than electron kinetic energy is transferred to the lattice. The resulting plasma is far from thermal equilibrium. The material is in essence converted from its initial solid-state directly into a fully ionized plasma on a time scale too short for thermal equilibrium to be established with the lattice. As a result, there is negligible heat conduction beyond the region removed resulting in negligible thermal stress or shock to the material beyond a few microns from the laser machined surface. Hydrodynamic expansion of the plasma eliminates the need for any ancillary techniques to remove material and produces extremely high quality machined surfaces. There is no detonation or deflagration of the explosive in the process and the material which is removed is rendered inert.

Portable radiography system using a relativistic electron beam  

DOE Patents (OSTI)

A portable radiographic generator is provided with an explosive magnetic flux compression generator producing the high voltage necessary to generate a relativistic electron beam. The relativistic electron beam is provided with target materials which generates the desired radiographic pulse. The magnetic flux compression generator may require at least two conventional explosively driven generators in series to obtain a desired output voltage of at least 1 MV. The cathode and anode configuration of the diode are selected to provide a switching action wherein a high impedance load is presented to the magnetic flux compression generator when the high voltage is being generated, and thereafter switching to a low impedance load to generate the relativistic electron beam. Magnetic flux compression generators can be explosively driven and provided in a relatively compact, portable form for use with the relativistic x-ray equipment.

ADVANCED WIRELESS CHARGING SYSTEM FOR PORTABLE ELECTRIC DEVICES  

E-Print Network (OSTI)

This paper presents a wireless charging system for portable electric devices. The important impacts of wireless charging systems on the global environment are first examined, and the two basic methods for wireless charging are then explained. The feasibility of applying each method to the wireless charging system is also analyzed. In order to achieve a high efficiency and more precise control for the wireless power transfer, the technology of a contactless charging board is used in this research. Because the experiments operated base on an induction cooker, the basic structure of the induction cooker are explained. Then the strategy of controling the output power is given. Finally, comprehensive experiments with efficiency tests, effective distance tests, and how the location of the coil would affect those important factors are given. The result shows that the method of contactless charging board is reliable for portable electric devices to achieve a relatively high charging efficiency and an acceptable charging distance.

Fuel cell systems for personal and portable power applications  

SciTech Connect

Fuel cells are devices that electrochemically convert fuel, usually hydrogen gas, to directly produce electricity. Fuel cells were initially developed for use in the space program to provide electricity and drinking water for astronauts. Fuel cells are under development for use in the automobile industry to power cars and buses with the advantage of lower emissions and higher efficiency than internal combustion engines. Fuel cells also have great potential to be used in portable consumer products like cellular phones and laptop computers, as well as military applications. In fact, any products that use batteries can be powered by fuel cells. In this project, we examine fuel cell system trade-offs between fuel cell type and energy storage/hydrogen production for portable power generation. The types of fuel cells being examined include stored hydrogen PEM (polymer electrolyte), direct methanol fuel cells (DMFC) and indirect methanol fuel cells, where methanol is reformed producing hydrogen. These fuel cells systems can operate at or near ambient conditions, which make them potentially optimal for use in manned personal power applications. The expected power production for these systems is in the range of milliwatts to 500 watts of electrical power for either personal or soldier field use. The fuel cell system trade-offs examine hydrogen storage by metal hydrides, carbon nanotubes, and compressed hydrogen tanks. We examine the weights each system, volume, fuel storage, system costs, system peripherals, power output, and fuel cell feasibility in portable devices.

They are used by the U.S. Department of Homeland Security (DHS) and other government agencies and organizations in various roles for border protection, law enforcement, and nonproliferation monitoring. In order to systematically document the operational performance of the common commercial off-the-shelf portable radiation detection systems, the DHS Domestic Nuclear Detection Office conducted a test and evaluation campaign conducted at the Nevada Test Site from January 18 to February 27, 2006. Named “Anole,” it was the first test of its kind in terms of technical design and test complexities. The Anole test results offer users information for selecting appropriate mission-specific portable radiation detection systems. The campaign also offered manufacturers the opportunity to submit their equipment for independent operationally relevant testing to subsequently improve their detector performance. This paper will present the design, execution, and methodologies of the DHS Anole portable radiation detection system test campaign.

A portable modular architecture for robotic manipulator control  

Science Conference Proceedings (OSTI)

A control architecture has been developed to provide a framework for robotic manipulator control. This architecture, called the Modular Integrated Control Architecture (MICA), has been successfully applied to two different manipulator systems. MICA is a portable system in two respects. First, it can be used for the control of different types of manipulator systems. Second, the MICA code is portable across several operating environments. This portability allows the sharing of common control code among various systems. A major portion of MICA is the precise control of multiple processors that have to be coordinated to control a manipulator system. By having NUCA control the processor synchronization, the system developer can concentrate on the specific aspects of a new manipulator system. MICA also provides standard functions for trajectory generation that can be used for most manipulators. Custom trajectory generators can be easily added to suit the needs of a particular robotic control system. Another facility that MICA provides is a simulation of the manipulator, allowing the control code to be simulated before trying it on a manipulator system. Using this technique, one can develop code for a manipulator system without risking damage to the arm during development.

Fuel Cells for Portable Power: 1. Introduction to DMFCs; 2. Advanced Materials and Concepts for Portable Power Fuel Cells  

DOE Green Energy (OSTI)

Thanks to generally less stringent cost constraints, portable power fuel cells, the direct methanol fuel cell (DMFC) in particular, promise earlier market penetration than higher power polymer electrolyte fuel cells (PEFCs) for the automotive and stationary applications. However, a large-scale commercialization of DMFC-based power systems beyond niche applications already targeted by developers will depend on improvements to fuel cell performance and performance durability as well as on the reduction in cost, especially of the portable systems on the higher end of the power spectrum (100-250 W). In this part of the webinar, we will focus on the development of advanced materials (catalysts, membranes, electrode structures, and membrane electrode assemblies) and fuel cell operating concepts capable of fulfilling two key targets for portable power systems: the system cost of $5/W and overall fuel conversion efficiency of 2.0-2.5 kWh/L. Presented research will concentrate on the development of new methanol oxidation catalysts, hydrocarbon membranes with reduced methanol crossover, and improvements to component durability. Time permitted, we will also present a few highlights from the development of electrocatalysts for the oxidation of two alternative fuels for the direct-feed fuel cells: ethanol and dimethyl ether.

A methanol sensor for portable direct methanol fuel cells  

Science Conference Proceedings (OSTI)

An aqueous methanol sensor for portable direct methanol fuel cell applications is demonstrated. The design is based on current output limited by methanol diffusion through a Nafion 117 perfluorosulfonic acid membrane. Steady-state polarization measurements demonstrate sensitivity to concentrations of 0 to 4 M over a temperature range of 40 to 80C. Furthermore, a correlation that is first order in concentration and temperature is demonstrated for concentrations of 0 to 3 M, with an accuracy of {+-}0.1 M. Measurements of transient response to step concentration change indicate a response time of about 10 to 50 s, depending primarily on temperature.

Flow metering is absolutely required for evaluation of energy usage. In fact, determining usages and heat balances without metering are simply educated guesses. Recent technological innovations in flow metering have produced clamp-on, portable flow meters to measure liquids. This paper reviews the principles of ultrasonic flow meters. Applications and costs of ultrasonic versus orifice flow meters are important to consider in energy audits. A discussion follows on 'how' and 'where' to use ultrasonic flowmeters. Estimated costs contained in this paper encompass equipment costs as well as installation costs associated with both ultrasonic and orifice meters.

Portable Apparatus for the Measurement of Environmental Radon and Thoron  

DOE Patents (OSTI)

The radometer is a portable instrument for the measurement of the concentration of atmospheric radon/thoron in a test area. A constant velocity pump pulls the air from the outside at a constant flow rate. If the air is too moist, some or all of the sample is passed through a desiccant filter prior to encountering an electrostatic filter. The electrostatic filter prevents any charged particles from entering the sampling chamber. Once the sample has entered the chamber, the progeny of the decay of radon/thoron are collected on a detector and measured. The measured data is compiled by a computer and displayed.

Portable water filtration system for oil well fractionation  

Science Conference Proceedings (OSTI)

The invention comprises a portable, multi-stage filtration system utilized in filtering water for an oil and gas stimulation process commonly known as fracking. Three stages are used, the first being a straining operation reducing the size of particulate matter in the water to about three-eighths of an inch. The second stage is a centrifugal separator, reducing the particle size to about 50 microns. The final stage utilizes a cartridge-type filter giving a final particle size in the water of about 5 microns. In this manner, water which is injected into the well head during the fracking process and which is obtained from readily available sources such as ponds, streams and the like is relatively free of particulate matter which can foul the fracking process. The invention, by virtue of being mounted on a trailer, is portable and thus can be easily moved from site to site. Water flow rates obtained using the invention are between 250 and 300 gallons per minute, sufficient for processing a small to medium sized well.

OPERATING PROCEDURE FOR THE PORTABLE ACOUSTIC MONITORING PACKAGE (PAMP)  

Science Conference Proceedings (OSTI)

The Portable Acoustic Monitoring Package (PAMP) has been designed to record and monitor acoustic signals in high-pressure natural gas (NG) transmission lines. Of particular interest are the three acoustic signals associated with a pipeline fracture. The system is portable (less than 30 lbm) and can be used at all line pressures up to 1000 psig. The PAMP requires a shut-off valve equipped 1/2 inch NPT access port in the pipeline. It is fully functional over the typical pressure range found in the natural gas transmission pipelines in the West Virginia, Virginia, Pennsylvania, and Ohio areas. With the use of the PAMP, a full spectrum of acoustic signals can be recorded and defined in terms of acoustic energy in decibels. To detect natural gas pipeline infringements and leaks, the acoustic energy generated inside the line is monitored with a sensitive pressure-equalized microphone and a step function type {Delta}p transducer. The assembly is mounted on a 1000 psig pipe fitting-tree called the PAMP. The electronics required to record, store and analyze the data are described within this report in the format of an operating manual.

Alpha Channeling in Mirror Machines  

SciTech Connect

Because of their engineering simplicity, high-?, and steady-state operation, mirror machines and related open-trap machines such as gas dynamic traps, are an attractive concept for achieving controlled nuclear fusion. In these open-trap machines, the confinement occurs by means of magnetic mirroring, without the magnetic field lines closing upon themselves within the region of particle confinement. Unfortunately, these concepts have not achieved to date very spectacular laboratory results, and their reactor prospects are dimmed by the prospect of a low Q-factor, the ratio of fusion power produced to auxiliary power. Nonetheless, because of its engineering promise, over the years numerous improvements have been proposed to enhance the reactor prospects of mirror fusion, such as tandem designs, end-plugging, and electric potential barriers.

A New Approach to Abstract Machines - Introduction to the Theory of Configuration Machines  

E-Print Network (OSTI)

An abstract machine is a theoretical model designed to perform a rigorous study of computation. Such a model usually consists of configurations, instructions, programs, inputs and outputs for the machine. In this paper we formalize these notions as a very simple algebraic system, called a configuration machine. If an abstract machine is defined as a configuration machine consisting of primitive recursive functions then the functions computed by the machine are always recursive. The theory of configuration machines provides a useful tool to study universal machines.

Portable electro-mechanically cooled high-resolution germanium detector  

SciTech Connect

We have integrated a small, highly-reliable, electro-mechanical cryo-cooler with a high-resolution germanium detector for portable/field applications. The system weighs 6.8 kg and requires 40 watts of power to operate once the detector is cooled to its operating temperature. the detector is a 500 mm{sup 2} by 20-mm thick low-energy configuration that gives a full-width at half maximum (FWHM) energy resolution of 523 eV at 122 keV, when cooled with liquid nitrogen. The energy resolution of the detector, when cooled with the electro-mechanical cooler, is 570 eV at 122 keV. We have field tested this system in measurements of plutonium and uranium for isotopic and enrichment information using the MGA and MGAU analysis programs without any noticeable effects on the results.

A Portable Expert System for Gas Turbine Maintenance  

E-Print Network (OSTI)

Combustion turbines for electric power generation and industrial applications have steadily increased in size, efficiency and prominence. The newest class of gas turbine-generators coming into service will deliver 150 megawatts, with turbine inlet temperatures of 2300° F. To sustain high levels of performance and reliability of this equipment, diagnostics and maintenance planning have also become increasingly important. Within the electric power industry, for example, as the overall fleet of gas turbines has aged, their annual service factor has increased to carry more of the peak load burden as reserve margins shrink. However, peaking duty requires frequent cycling with large thermal stresses that tend to shorten the life of hot section components. To assist the industry in meeting these needs, EPRI has developed The SA?VANT™ System. This unique multi-faceted portable unit will apply a broad range of expert systems in the workplace for power plant maintenance, including turbomachinery of all types, but especially for gas turbines.

Exposure to ionizing radiation in the emergency department from commonly performed portable radiographs  

SciTech Connect

To accurately assess the potential hazard of exposure to ionizing radiation from portable radiographs taken in the emergency department, a study was performed to measure such radiation at different distances from the edge of an irradiated field during portable cervical-spine (pC-S), portable chest radiograph (pCXR), and portable anteroposterior-pelvis (pAP-pelvis) radiographs. For all three types of portable radiographs, radiation exposure is a function of distance from the beam. However, at 40 cm (15 inches) away from the beam during a pC-S or pCXR and at 160 cm (63 inches) from a pAP-pelvis film, exposure is minimal. At these distances one would need to be exposed to more than 1,200 such radiographs to equal background environmental ionizing radiation. Medical personnel should not have to leave a patient care area for fear of undue acute and chronic radiation exposure while portable radiographs are performed in the ED. By using protective garments and standing appropriate distances away from the patient, continuous patient care can be maintained while portable radiographs are taken in the ED.

Design of a portable CAT scanner for utility pole inspection  

SciTech Connect

Work is under way at the University of Missouri, Columbia (UMC) to design, build, and test a portable computerized axial tomography (CAT) device for the nondestructive, field imaging of wooden utility poles. CAT is a well-established medical technology that has recently been applied to a number of industrial applications. Wooden utility poles are prone to rot and decay at ground level; current techniques to assess this loss of strength are relatively primitive, i.e., tapping the pole (hitting the pole with a hammer) or boring into the pole for samples and then testing inside the bore hole with an electrical pulse device. The accuracy in identifying poles needing replacement using these techniques is approx. 70%. Since the cost of replacing a pole ranges from hundreds to thousands of dollars, an accurate, nondestructive method is needed. CAT can accurately image a wooden utility pole (since the size, density, and atomic elements of a pole are similar to the human head to torso), as was confirmed by imaging poles using the UMC nuclear engineering EMI-1010 medical scanner. Detailed images have been produced showing the ring structure of the wood and voids due to rot or decay. Images approaching this quality have also been produced on living trees using semiportable systems by other researchers.

New portable sensor system for rotational seismic motion measurements  

SciTech Connect

A new mechanical sensor system for recording the rotation of ground velocity has been constructed. It is based on measurements of differential motions between paired sensors mounted along the perimeter of a rigid (undeformable) disk. The elementary sensors creating the pairs are sensitive low-frequency geophones currently used in seismic exploration to record translational motions. The main features of the new rotational seismic sensor system are flat characteristics in the wide frequency range from 1 to 200 Hz and sensitivity limit of the order of 10{sup -8} rad/s. Notable advantages are small dimensions, portability, easy installation and operation in the field, and the possibility of calibrating the geophones in situ simultaneously with the measurement. An important feature of the instrument is that it provides records of translational seismic motions together with rotations, which allows many important seismological applications. We have used the new sensor system to record the vertical rotation velocity due to a small earthquake of M{sub L}=2.2, which occurred within the earthquake swarm in Western Bohemia in autumn 2008. We found good agreement of the rotation record with the transverse acceleration as predicted by theory. This measurement demonstrates that this device has a much wider application than just to prospecting measurements, for which it was originally designed.

Experiments with the Dragon Machine  

Science Conference Proceedings (OSTI)

The basic characteristics of a self-sustaining chain reaction were demonstrated with the Chicago Pile in 1943, but it was not until early 1945 that sufficient enriched material became available to experimentally verify fast-neutron cross-sections and the kinetic characteristics of a nuclear chain reaction sustained with prompt neutrons alone. However, the demands of wartime and the rapid decline in effort following the cessation of hostilities often resulted in the failure to fully document the experiments or in the loss of documentation as personnel returned to civilian pursuits. When documented, the results were often highly classified. Even when eventually declassified, the data were often not approved for public release until years later.2 Even after declassification and approval for public release, the records are sometimes difficult to find. Through a fortuitous discovery, a set of handwritten notes by ''ORF July 1945'' entitled ''Dragon - Research with a Pulsed Fission Reactor'' was found by William L. Myers in an old storage safe at Pajarito Site of the Los Alamos National Laboratory3. Of course, ORF was identified as Otto R. Frisch. The document was attached to a page in a nondescript spiral bound notebook labeled ''494 Book'' that bore the signatures of Louis Slotin and P. Morrison. The notes also reference an ''Idea LS'' that can only be Louis Slotin. The discovery of the notes led to a search of Laboratory Archives, the negative files of the photo lab, and the Report Library for additional details of the experiments with the Dragon machine that were conducted between January and July 1945. The assembly machine and the experiments were carefully conceived and skillfully executed. The analyses--without the crutch of computers--display real insight into the characteristics of the nuclear chain reaction. The information presented here provides what is believed to be a complete collection of the original documentation of the observations made with the Dragon Machine in early 1945.

Quantum Cloning Machines and the Applications  

E-Print Network (OSTI)

No-cloning theorem is fundamental for quantum mechanics and for quantum information science that states an unknown quantum state cannot be cloned perfectly. However, we can try to clone a quantum state approximately with the optimal fidelity, or instead, we can try to clone it perfectly with the largest probability. Thus various quantum cloning machines have been designed for different quantum information protocols. Specifically, quantum cloning machines can be designed to analyze the security of quantum key distribution protocols such as BB84 protocol, six-state protocol, B92 protocol and their generalizations. Some well-known quantum cloning machines include universal quantum cloning machine, phase-covariant cloning machine, the asymmetric quantum cloning machine and the probabilistic quantum cloning machine etc. In the past years, much progress has been made in studying quantum cloning machines and their applications and implementations, both theoretically and experimentally. In this review, we will give a complete description of those important developments about quantum cloning and some related topics. On the other hand, this review is self-consistent, and in particular, we try to present some detailed formulations so that further study can be taken based on those results. In addition, this review also contains some new results, for example, the study of quantum retrodiction protocol.

An abstract-device interface for implementing portable parallel-I/O interfaces  

Science Conference Proceedings (OSTI)

Portable parallel programming has been hampered by the lack of a single, standard, portable application-programmer`s interface (API) for parallel I/O. Instead, the programmer must choose from several different APIs, many of which are not portable. To alleviate this problem, the authors have developed an abstract-device interface for parallel I/O, called ADIO. ADIO is not intended as a new API; rather, it is a strategy for implementing other APIs in a simple, portable, and efficient manner. ADIO facilitates the implementation of any existing or new API on any existing or new file system. ADIO thus enables users to experiment with different APIs, a feature that, they think, would help in the definition of a standard API. It also makes existing applications portable across a wide range of platforms. In this paper, they introduce the concept of ADIO. They describe the design of ADIO and its use in implementing APIs. They have currently implemented subsets of the Intel PFS, IBM PIOFS, and MPI-IO APIs on both the PFS and PIOFS file systems. As a result, they are able to run IBM PIOFS applications on the Intel Paragon, Intel PFS applications on the IBM SP, and MPI-IO applications on both systems. They report performance results obtained from two test programs and one real production application on the SP and Paragon. These results indicate that the performance overhead of using ADIO as an implementation strategy is negligible.

Portable Hand-Held Electrochemical Sensor for the Transuranics  

Science Conference Proceedings (OSTI)

During the four-year period of the grant all of the goals of the originally proposed work were achieved, and some additional accomplishments are here reported. Two types of sensors were designed and built in the lab, capable of detecting uranium, plutonium and thorium at the 10 part-per-trillion level. The basis of both sensor types is a specially designed polymer having selective binding sites for actinyl ions of the form MO{sub 2}{sup 2+}(aq), where M is any actinide in the +6 oxidation state. This binding site also traps ions of the form MO{sub 2}{sup +}(aq), where M is any actinide in the +4 oxidation state. In this way, the polymer is responsive to the two most common water-soluble ions of the actinide series. The chelating ring responsible for binding the actinyl ions was identified from the literature, calix[n]arene where n = 6. Several versions of this sensing polymer were coated on conductive substrates and demonstrated for actinide sensing. An optimized sensor was developed and is fully described in this report. It has a polymer bilayer, fabricated under the particular conditions given below. Two different operating modes were demonstrated having different capabilities. One is the chemFET mode (a FET is a field effect transistor) and the other is the voltammetric mode. These two sensors give complementary information regarding the actinide species in a sample. Therefore our recommendation is that both be used together in a probe. A detailed design for such a probe has been filed as a patent application with the United States Patent Office, and is patent pending. The sensing polymer incorporating this actinyl-chelating ring was tested under a variety of conditions and the operating limits were determined. A full factorial experiment testing the polymerization method was conducted to optimize performance and characteristics of this polymer. The actinyl-sensing polymer was also deposited on the gate of a field effect transistor (FET) and demonstrated as a sensitive detector for uranium. Millimeter scale electrodes, operated by a hand-held instrument assembled in this lab and operated in the voltammetric mode, were transported to the DOE-Nevada test site (Las Vegas, NV) where field detection and quantitation of plutonium, uranium, and a mixture of these two elements was also demonstrated. Several probe designs were prepared, built and tested including probes with movable protective windows. A miniature, battery powered potentiostat was designed, built and demonstrated for use in a hand-held field portable instrument. This work was performed largely by undergraduates who gained valuable research experience, and many of them have continued on to graduate schools. In addition, they all gained exposure to and appreciation for national security research, in particular non-proliferation research. Four graduate students participated and one earned the MS degree on this project.

Baseline Test Specimen Machining Report  

SciTech Connect

The Next Generation Nuclear Plant (NGNP) Project is tasked with selecting a high temperature gas reactor technology that will be capable of generating electricity and supplying large amounts of process heat. The NGNP is presently being designed as a helium-cooled high temperature gas reactor (HTGR) with a large graphite core. The graphite baseline characterization project is conducting the research and development (R&D) activities deemed necessary to fully qualify nuclear-grade graphite for use in the NGNP reactor. Establishing nonirradiated thermomechanical and thermophysical properties by characterizing lot-to-lot and billet-to-billet variations (for probabilistic baseline data needs) through extensive data collection and statistical analysis is one of the major fundamental objectives of the project. The reactor core will be made up of stacks of graphite moderator blocks. In order to gain a more comprehensive understanding of the varying characteristics in a wide range of suitable graphites, any of which can be classified as “nuclear grade,” an experimental program has been initiated to develop an extensive database of the baseline characteristics of numerous candidate graphites. Various factors known to affect the properties of graphite will be investigated, including specimen size, spatial location within a graphite billet, specimen orientation within a billet (either parallel to [P] or transverse to [T] the long axis of the as-produced billet), and billet-to-billet variations within a lot or across different production lots. Because each data point is based on a certain position within a given billet of graphite, particular attention must be paid to the traceability of each specimen and its spatial location and orientation within each billet. The evaluation of these properties is discussed in the Graphite Technology Development Plan (Windes et. al, 2007). One of the key components in the evaluation of these graphite types will be mechanical testing on specimens drawn from carefully controlled sections of each billet. To this end, this report will discuss the machining of the first set of test specimens that will be evaluated in this program through tensile, compressive, and flexural testing. Validation that the test specimens have been produced to the tolerances required by the applicable ASTM standards, and to the quality control levels required by this program, will demonstrate the viability of sending graphite to selected suppliers that will provide valuable and certifiable data to future data sets that are integral to the NGNP program and beyond.

Machine Maintenance Integrated Performance Support System  

SciTech Connect

The objectives of this partnership project were to develop a preventive maintenance checklist program, a troubleshooting system for the Vertical Turning Center (VTC)-5, an on-line manual, and to integrate these components with a custom browser that would run on the VTC-5 machine's controller and would support future internet/intranet delivery. Kingsbury provided subject matter experts from engineering, manufacturing, and technical support. They also provided photographs, schematics, and CAD drawings, which AlliedSignal Federal Manufacturing and Technologies (ASFM and T) digitized for use in the final program. Information from The Kingsbury troubleshooting experts were interviewed regarding symptoms and root causes of system malfunctions This knowledge was captured and from it, fault trees were developed. These trees were then incorporated into the EPSS as a troubleshooting tool. The troubleshooting portion of the system presents simple questions to the machine operator in order to determine the likely cause or causes of malfunctions and then recommends systematic corrective actions. The on-line reference manual, covering operations and maintenance, provides text and illustrations to the machine operator in a traditional structure, but additionally offers the capability to search voluminous amounts of technical data and retrieve specific information on request. The maintenance portion of the EPSS includes checklists that are displayed daily, weekly, monthly, and annually, as appropriate, on the VTC-5 controller screen. The controller software is unavailable for machining parts until the machine tool operator goes through and checks off all of the checklist items. This project provided the team with a detailed understanding of the knowledge and information required to produce and support advanced machine tools. In addition, it resulted in the design and construction of a prototype VTC-5 EPSS containing all the logic and interfaces necessary to integrate operations and maintenance information from other Kingsbury machine tools.

Cost Effective Machining Of Ceramics (CEMOC)  

SciTech Connect

The purpose of the CEMOC program was to support U.S. industry needs in fabricating precision components, from difficult to machine materials, while maintaining and enhancing the precision manufacturing skills of the Oak Ridge Complex. Oak Ridge and partner company personnel worked in a team relationship wherein each contributed equally to the success of the program. In general, Oak Ridge contributed a wider range of expertise to a given task while the companies provided operations-specific equipment and shop-floor services. Process control technologies, machining procedures and parameters, and coolant-related environmental tasks were the primary focus areas. The companies were very pleased with the results of the CRADAs and are planning on continuing the relationships. Finish machining operations contribute the majority of the costs associated with fabricating high quality ceramic products. These components are typically used in harsh environments such as diesel engines, defense machinery, and automotive components. The required finishing operations involve a variety of technologies including process controls, machine coolants, product certification, etc. and are not limited only to component grinding methods. The broad range of manufacturing problem solving expertise available in Oak Ridge provided resources that were far beyond what are typically available to the CRADA partners. These partners contributed equipment, such as state-of-the-art machine tools, and operation-specific experience base. In addition, addressing these challenging tasks enabled Oak Ridge personnel to maintain familiarity with rapidly advancing technologies, such as those associated with computer control systems.

Trunnion Collar Removal Machine - Gap Analysis Table  

SciTech Connect

The purpose of this document is to review the existing the trunnion collar removal machine against the ''Nuclear Safety Design Bases for License Application'' (NSDB) [Ref. 10] requirements and to identify codes and standards and supplemental requirements to meet these requirements. If these codes and standards can not fully meet these requirements then a ''gap'' is identified. These gaps will be identified here and addressed using the ''Trunnion Collar Removal Machine Design Development Plan'' [Ref. 15]. The codes and standards, supplemental requirements, and design development requirements for the trunnion collar removal machine are provided in the gap analysis table (Appendix A, Table 1). Because the trunnion collar removal machine is credited with performing functions important to safety (ITS) in the NSDB [Ref. 10], design basis requirements are applicable to ensure equipment is available and performs required safety functions when needed. The gap analysis table is used to identify design objectives and provide a means to satisfy safety requirements. To ensure that the trunnion collar removal machine performs required safety functions and meets performance criteria, this portion of the gap analysis tables supplies codes and standards sections and the supplemental requirements and identifies design development requirements, if needed.

Multi-winding homopolar electric machine  

SciTech Connect

A multi-winding homopolar electric machine and method for converting between mechanical energy and electrical energy. The electric machine includes a shaft defining an axis of rotation, first and second magnets, a shielding portion, and a conductor. First and second magnets are coaxial with the shaft and include a charged pole surface and an oppositely charged pole surface, the charged pole surfaces facing one another to form a repulsive field therebetween. The shield portion extends between the magnets to confine at least a portion of the repulsive field to between the first and second magnets. The conductor extends between first and second end contacts and is toroidally coiled about the first and second magnets and the shield portion to develop a voltage across the first and second end contacts in response to rotation of the electric machine about the axis of rotation.

Passive machine augmented composite for multifunctional properties  

E-Print Network (OSTI)

This dissertation studies by experiment and numerical analysis an advanced composite material (Machine Augmented Composite or MAC) for enhancement of the passive damping while maintaining its stiffness. This MAC is composed of a pre-buckled wall structure placed within a viscoelastic matrix. The pre-buckled machine can contain viscous fluids for additional energy dissipation. For the experiments, the MAC was fabricated by using rigid and soft polyurethane as a machine and matrix material respectively. Various viscosity fluids (0.83 ~ 4730 cps) filled the inner-channel of the machine structure. Dynamic properties such as tan ?? and the loss modulus (E") of the composite were measured and compared with those of a homogeneous matrix sample over a frequency range of 0.1 to 100 Hz at room temperature through load-controlled cyclic testing. Measured tan ?? and loss modulus values for the composite were higher than those of the matrix alone in the 1 to 40 Hz range. However the viscous fluid effects on the overall damping properties were small. The performance of a theoretical MAC was explored through numerical analysis. The amount of inner-channel gap closure was calculated for various matrix Poisson??s ratios, for various Young??s modulus ratios between the machine and matrix (Emachine/Ematrix), and for the volume fraction of the machines. The most desirable performance of the composite was obtained when the matrix Poisson??s ratio was 0.49, and there was interaction between the Emachine/Ematrix and the volume fraction of the machines. Also the proper volume fraction range of the machine was predicted to be between 0.15 and 0.2 for the lamina shape MAC. Based upon the analysis, a sandwich structure MAC was fabricated and tested. This composite showed 11 times higher stiffness than the matrix without loosing the matrix damping property. This dissertation shows that the research met these objectives: 1) the MAC concept is effective for passive damping of vibrations, 2) that material combinations studied here had optimal combinations for best performance, and 3) that this is a promising field study for future passive and active materials development.

High slot utilization systems for electric machines  

DOE Patents (OSTI)

Two new High Slot Utilization (HSU) Systems for electric machines enable the use of form wound coils that have the highest fill factor and the best use of magnetic materials. The epoxy/resin/curing treatment ensures the mechanical strength of the assembly of teeth, core, and coils. In addition, the first HSU system allows the coil layers to be moved inside the slots for the assembly purpose. The second system uses the slided-in teeth instead of the plugged-in teeth. The power density of the electric machine that uses either system can reach its highest limit.

Development and Performance of the PHOT (Portable High-Speed Occultation Telescope) Systems  

E-Print Network (OSTI)

The PHOT (Portable High-Speed Occultation Telescope) systems were developed for the specific purpose of observing stellar occultations by solar system objects. Stellar occultations have unique observing constraints: they may only be observable from certain parts of the globe; they often require a rapid observing cadence; and they require accurate timestamp information for each exposure. The PHOT systems consist of 14" telescopes, CCD cameras, camera mounting plates, GPS-based time standards, and data acquisition computers. The PHOT systems are similar in principle to the POETS systems (Portable Occultation, Eclipse and Transit Systems, described by Souza et al. 2006 and reported on by Gulbis et al. 2008), with the main differences being (a) different CCD/Cameras with slightly different specifications and (b) a stand-alone custom-built time standard used by PHOT, whereas POETS uses a commercial time-standard that is controlled from a computer. Since 2005, PHOT systems have been deployed on over two dozen occas...

Radioactive air emissions notice of construction portable/temporary radioactive air emission units  

SciTech Connect

This notice of construction (NOC) requests a categorical approval for construction and operation of three types of portable/temporary radionuclide airborne emission units (PTRAEUs). These three types are portable ventilation-filter systems (Type 1), mobile sample preparation facilities (Type II), and mobile sample screening and analysis facilities (Type III). Approval of the NOC application is intended to allow construction and operation of the three types of PTRAEUs without prior project-specific approval. Environmental cleanup efforts on the Hanford Site often require the use of PTRAEUS. The PTRAEUs support site characterization activities, expedited response actions (ERAs), sampling and monitoring activities, and other routine activities. The PTRAEUs operate at various locations around the Hanford Site.

Design of programmable, low power, low dropout voltage regulators for portable applications  

E-Print Network (OSTI)

As portable electronics constantly find their way into the hands of eager consumers, the demands placed on these products and their circuits are ever increasing. More features and more performance are continuously demanded by consumers. This feature-driven market has brought with it several constraints on the type of circuits utilized in developing these portable devices. Cell-Phones, PDA's, MP3 players and various other portable electronics require different voltage levels to power different architectures that realize the many features within the device. This work demonstrates a technique to design Programmable Low Power Low Dropout Voltage Regulators (LDO). The LDO proposed in this research utilizes a fast-transient feedback loop in order to improve transient response and guarantee stability in all the programmable output levels. Specifically, the main parameters to be improved are stability over the entire load current range, reduced overshoot and undershoot variations in transient response, reduction of LDO deflection voltage, minimization of standby current and low voltage (Vin = 1.2V) operation.

Malware Detection Module using Machine Learning Algorithms to Assist in Centralized Security in Enterprise Networks  

E-Print Network (OSTI)

Malicious software is abundant in a world of innumerable computer users, who are constantly faced with these threats from various sources like the internet, local networks and portable drives. Malware is potentially low to high risk and can cause systems to function incorrectly, steal data and even crash. Malware may be executable or system library files in the form of viruses, worms, Trojans, all aimed at breaching the security of the system and compromising user privacy. Typically, anti-virus software is based on a signature definition system which keeps updating from the internet and thus keeping track of known viruses. While this may be sufficient for home-users, a security risk from a new virus could threaten an entire enterprise network. This paper proposes a new and more sophisticated antivirus engine that can not only scan files, but also build knowledge and detect files as potential viruses. This is done by extracting system API calls made by various normal and harmful executable, and using machine l...

Positional reference system for ultraprecision machining  

DOE Patents (OSTI)

A stable positional reference system for use in improving the cutting tool-to-part contour position in numerical controlled-multiaxis metal turning machines is provided. The reference system employs a plurality of interferometers referenced to orthogonally disposed metering bars which are substantially isolated from machine strain induced position errors for monitoring the part and tool positions relative to the metering bars. A microprocessor-based control system is employed in conjunction with the plurality of position interferometers and part contour description data inputs to calculate error components for each axis of movement and output them to corresponding axis drives with appropriate scaling and error compensation. Real-time position control, operating in combination with the reference system, makes possible the positioning of the cutting points of a tool along a part locus with a substantially greater degree of accuracy than has been attained previously in the art by referencing and then monitoring only the tool motion relative to a reference position located on the machine base.

MONICA: a compact, portable dual gamma camera system for mouse whole-body imaging  

Science Conference Proceedings (OSTI)

Introduction We describe a compact, portable dual-gamma camera system (named "MONICA" for MObile Nuclear Imaging CAmeras) for visualizing and analyzing the whole-body biodistribution of putative diagnostic and therapeutic single photon emitting radiotracers in animals the size of mice. Methods Two identical, miniature pixelated NaI(Tl) gamma cameras were fabricated and installed ?looking up? through the tabletop of a compact portable cart. Mice are placed directly on the tabletop for imaging. Camera imaging performance was evaluated with phantoms and field performance was evaluated in a weeklong In-111 imaging study performed in a mouse tumor xenograft model. Results Tc-99m performance measurements, using a photopeak energy window of 140 keV?10%, yielded the following results: spatial resolution (FWHM at 1 cm), 2.2 mm; sensitivity, 149 cps (counts per seconds)/MBq (5.5 cps/?Ci); energy resolution (FWHM, full width at half maximum), 10.8%; count rate linearity (count rate vs. activity), r2=0.99 for 0?185 MBq (0?5 mCi) in the field of view (FOV); spatial uniformity, <3% count rate variation across the FOV. Tumor and whole-body distributions of the In-111 agent were well visualized in all animals in 5-min images acquired throughout the 168-h study period. Conclusion Performance measurements indicate that MONICA is well suited to whole-body single photon mouse imaging. The field study suggests that inter-device communications and user-oriented interfaces included in the MONICA design facilitate use of the system in practice. We believe that MONICA may be particularly useful early in the (cancer) drug development cycle where basic whole-body biodistribution data can direct future development of the agent under study and where logistical factors, e.g., limited imaging space, portability and, potentially, cost are important.

TWRS hydrogen mitigation portable standard hydrogen monitoring system platform design and fabrication engineering task plan  

DOE Green Energy (OSTI)

The primary function of portable gas monitoring is to quickly determine tank vapor space gas composition and gas release rate, and to detect gas release events. Characterization of the gas composition is needed for safety analysis. The lower flammability limit, as well as the peak burn temperature and pressure, are dependent upon the gas composition. If there is little or no knowledge about the gas composition, safety analysis utilize compositions that yield the worst case in a deflagration or detonation. This conservative approach to unknowns necessitates a significant increase in administrative and engineering costs. Knowledge of the true composition could lead to reductions in the assumptions and therefore contribute to a reduction in controls and work restrictions. Also, knowledge of the actual composition will be required information for the analysis that is needed to remove tanks from the Watch List. Similarly, the rate of generation and release of gases is required information for performing safety analysis, developing controls, designing equipment, and closing safety issues. To determine release rate, both the gas concentrations and the dome space ventilation rates (exhauster flow rate or passive dome/atmosphere exchange rate) are needed. Therefore, to quickly verify waste tank categorization or to provide additional characterization for tanks with installed gas monitoring, a temporary, portable standard hydrogen monitoring system is needed that can be used to measure gas compositions at both high and low sensitivities.

An Iterative Algorithm for Battery-Aware Task Scheduling on Portable Computing Platforms  

E-Print Network (OSTI)

In this work we consider battery powered portable systems which either have Field Programmable Gate Arrays (FPGA) or voltage and frequency scalable processors as their main processing element. An application is modeled in the form of a precedence task graph at a coarse level of granularity. We assume that for each task in the task graph several unique design-points are available which correspond to different hardware implementations for FPGAs and different voltage-frequency combinations for processors. It is assumed that performance and total power consumption estimates for each design-point are available for any given portable platfrom, including the peripheral components such as memory and display power usage. We present an iterative heuristic algorithm which finds a sequence of tasks along with an appropriate design-point for each task, such that a deadline is met and the amount of battery energy used is as small as possible.

Note: A portable pulsed neutron source based on the smallest sealed-type plasma focus device  

Science Conference Proceedings (OSTI)

Development and operation of a portable and compact pulsed neutron source based on sealed-type plasma focus (PF) device are reported. The unit is the smallest sealed-type neutron producing PF device. The effective volume of the PF unit is 33 cm{sup 3} only. A compact size single capacitor (4 {mu}F) is used as the energy driver. A battery based power supply unit is used for charging the capacitor and triggering the spark gap. The PF unit is operated at 10 kV (200 J) and at a deuterium gas filling pressure of 8 mb. The device is operated over a time span of 200 days and the neutron emissions have been observed for 200 shots without changing the gas in between the shots. The maximum yield of this device is 7.8 x 10{sup 4} neutrons/pulse. Beyond 200 shots the yield is below the threshold (1050 neutrons/pulse) of our {sup 3}He detector. The neutron energy is evaluated using time of flight technique and the value is (2.49 {+-} 0.27) MeV. The measured neutron pulse width is (24 {+-} 5) ns. Multishot and long duration operations envisage the potentiality of such portable device for repetitive mode of operation.

Machine augmented composite materials for damping purposes  

E-Print Network (OSTI)

In this study the energy dissipation performance of machine augmented composite (MAC) materials is investigated. MAC materials are formed by inserting simple machines into a matrix material. In this work the machines take the form of fluid filled tubes, and the tube cross-sectional geometry induces fluid flow when it is deformed in its plane. This flow dissipates mechanical energy, and thus provides the composite material with attractive damping properties. The objective of this study is to gain insight into the geometry, the material property combinations, and the boundary conditions that are effective in producing high damping MAC materials. Particular attention is given to tube geometry and to dimensionless parameters that govern the energy dissipation efficiency of a MAC lamina. An important dimensionless parameter is the ratio of solid elastic moduli to the product of the driving frequency and the fluid dynamic viscosity. This is a measure of the ratio of elastic forces in the solid material to the viscous forces in the fluid material that makes up a MAC lamina. Governing equations and simulation methods are discussed. Simplified equations are derived to predict the pressure generated when a tube/matrix cell is squeezed with zero pressure end conditions. Transient, three dimensional finite element models are also used to predict the performance of the damping MAC materials with zero pressure at the ends of the tubes. For the geometry and material properties considered, the highest energy dissipation efficiency predicted by these models is approximately 0.8 out of a maximum of 1.0.

Ccg supertags in factored statistical machine translation  

E-Print Network (OSTI)

Combinatorial Categorial Grammar (CCG) supertags present phrase-based machine translation with an opportunity to access rich syntactic information at a word level. The challenge is incorporating this information into the translation process. Factored translation models allow the inclusion of supertags as a factor in the source or target language. We show that this results in an improvement in the quality of translation and that the value of syntactic supertags in flat structured phrase-based models is largely due to better local reorderings. 1

Edge diagnostics for tandem mirror machines  

SciTech Connect

The edge plasma in a tandem mirror machine shields the plasma core from cold neutral gas and impurities. A variety of diagnostics are used to measure the fueling, shielding, and confinement of the edge plasma in both the end plug and central cell regions. Fast ion gauges and residual gas analyzers measure the gas pressure and composition outside of the plasma. An array of Langmuir probes is used to measure the electron density and temperature. Extreme ultraviolet (euv) and visible spectroscopy are used to measure both the impurity and deuterium densities and to estimate the shielding factor for the core plasma. The linear geometry of a tandem mirror also allows direct measurements of the edge plasma by sampling the ions and electrons lost but the ends of the machine. Representative data obtained by these diagnostics during operation of the Tandem Mirror Experiment (TMX) and Tandem Mirror Experiment-Upgrade (TMX-U) experiments are presented. Diagnostics that are currently being developed to diagnose the edge plasma are also discussed.

Evaluation of machining dispersions for turning process  

E-Print Network (OSTI)

In this article we propose to extend the model of simulation of dispersions in turning based on the geometrical specifications. Our study is articulated around two trends of development: the first trend relates to the geometrical model. The geometrical model suggested must allow a follow-up of the geometry of the part during the simulation of machining. It is thus a question of carrying out a systematic treatment of the whole dimensioning and tolerancing process while being based on the principles of the \\DeltaL method. We also planned to integrate this type of specification in the model of simulation of machining suggested. It is more generally a question of extending the traditional model for better taking into account the multi axis specification of coaxiality and perpendicularity on the turned workpieces. The second trend of our study relates to the widening of the field of application of the model. We propose to extend the field of application of the model by taking into account the modifications of several parameters of the manufacturing process plans, likely to involve variations of dispersions.

Automatic tool path generation for finish machining  

SciTech Connect

A system for automatic tool path generation was developed at Sandia National Laboratories for finish machining operations. The system consists of a commercially available 5-axis milling machine controlled by Sandia developed software. This system was used to remove overspray on cast turbine blades. A laser-based, structured-light sensor, mounted on a tool holder, is used to collect 3D data points around the surface of the turbine blade. Using the digitized model of the blade, a tool path is generated which will drive a 0.375 inch diameter CBN grinding pin around the tip of the blade. A fuzzified digital filter was developed to properly eliminate false sensor readings caused by burrs, holes and overspray. The digital filter was found to successfully generate the correct tool path for a blade with intentionally scanned holes and defects. The fuzzified filter improved the computation efficiency by a factor of 25. For application to general parts, an adaptive scanning algorithm was developed and presented with simulation results. A right pyramid and an ellipsoid were scanned successfully with the adaptive algorithm.

HYDROGEN STORAGE SOLUTIONS IN SUPPORT OF DOD WARFIGHTER PORTABLE POWER APPLICATIONS  

DOE Green Energy (OSTI)

From Personal Digital Assistants (PDAs) to cell phones our high-tech world, today, is demanding smaller, lighter weight and higher capacity portable power devices. Nowhere has this personal power surge been more evident than in today's U.S Warfighter. The modern Warfighter is estimated to carry from 65 to 95 pounds of supplies in the field with over 30 pounds of this dedicated to portable power devices. These devices include computer displays, infrared sights, Global Positioning Systems (GPS), night vision and a variety of other sensor technologies. Over 80% of the energy needed to power these devices comes from primary (disposable) batteries. It is estimated that a brigade will consume as much as 7 tons of batteries in a 72 hour mission at a cost of $700,000. A recent comprehensive study on the energy needs of the future warrior published by the National Academy of Science in 2004 made a variety of recommendations for average power systems from 20 to 1,000 watts. For lower power systems recommendations included pursuing science and technology initiatives focused on: (1) 300 watt-hours per kilogram (Wh/kg) secondary battery technologies; (2) smart hybrids; and (3) fuel cells (with greater than 6 wt% hydrogen storage). Improved secondary (rechargeable) batteries may be the ideal solution for military power systems due to their ease of use and public acceptance. However, a 3X improvement in their specific energy density is not likely anytime soon. Today's Lithium Ion batteries, at about 150 Wh/kg, fall well short of the energy density that is required. Future battery technology may not be the answer since many experts do not predict more than a 2X improvement in Lithium battery systems over the next 10 years. That is why most auto companies have abandoned all electric vehicles in favor of fuel cells and hybrid vehicles. Fuel cells have very high specific energy densities but achieving high energy values will depend on the energy density and the storage method of its fuel. Improved methods of safely and efficiently storing larger amounts of hydrogen will be a key development area for portable fuel cell power systems. Despite their high potential energy, fuel cells exhibit low power densities. That is why many systems today are going hybrid. Hybrid systems typically combine low energy and high power components with high energy and low power components. Typical configurations include capacitors and fuel cells or batteries and fuel cells. If done correctly, a hybrid system often can have both high energy and high power density even higher than any of the individual components.

Estimation of radiative properties and temperature distributions in coal-fired boiler furnaces by a portable image processing system  

Science Conference Proceedings (OSTI)

This paper presented an experimental investigation on the estimation of radiative properties and temperature distributions in a 670 t/h coal-fired boiler furnace by a portable imaging processing system. The portable system has been calibrated by a blackbody furnace. Flame temperatures and emissivities were measured by the portable system and equivalent blackbody temperatures were deduced. Comparing the equivalent blackbody temperatures measured by the portable system and the infrared pyrometer, the relative difference is less than 4%. The reconstructed pseudo-instantaneous 2-D temperature distributions in two cross-sections can disclose the combustion status inside the furnace. The measured radiative properties of particles in the furnace proved there is significant scattering in coal-fired boiler furnaces and it can provide useful information for the calculation of radiative heat transfer and numerical simulation of combustion in coal-fired boiler furnaces. The preliminary experimental results show this technology will be helpful for the combustion diagnosis in coal-fired boiler furnaces. (author)

Portable NDA Equipment for Enrichment Measurements in the HEU Transparency Program  

SciTech Connect

The Highly Enriched Uranium (HEU) Transparency Program has used portable nondestructive assay (NDA) equipment to measure the {sup 235}U enrichment of material subject to the transparency agreement since 1997. The equipment is based on the 'enrichment meter' method and uses low-resolution sodium iodide (NaI(Tl)) detectors. Although systems using high-purity germanium (HPGe) detectors can produce more accurate results we have found that the results with NaI(Tl) detectors are quite adequate for the requirements of the transparency agreement. This paper will describe the details of the equipment's operation, calibration, testing, and deployment in Russia. We will also provide a comparison of the units originally deployed in 1997 with the upgraded systems that were deployed in 2003.

Dry, portable calorimeter for nondestructive measurement of the activity of nuclear fuel  

DOE Patents (OSTI)

The activity of a quantity of heat-producing nuclear fuel is measured rapidly, accurately and nondestructively by a portable dry calorimeter comprising a preheater, an array of temperature-controlled structures comprising a thermally guarded temperature-controlled oven, and a calculation and control unit. The difference between the amounts of electric power required to maintain the oven temperature with and without nuclear fuel in the oven is measured to determine the power produced by radioactive disintegration and hence the activity of the fuel. A portion of the electronic control system is designed to terminate a continuing sequence of measurements when the standard deviation of the variations of the amount of electric power required to maintain oven temperature is within a predetermined value.

MC++: A parallel, portable, Monte Carlo neutron transport code in C++  

SciTech Connect

MC++ is an implicit multi-group Monte Carlo neutron transport code written in C++ and based on the Parallel Object-Oriented Methods and Applications (POOMA) class library. MC++ runs in parallel on and is portable to a wide variety of platforms, including MPPs, SMPs, and clusters of UNIX workstations. MC++ is being developed to provide transport capabilities to the Accelerated Strategic Computing Initiative (ASCI). It is also intended to form the basis of the first transport physics framework (TPF), which is a C++ class library containing appropriate abstractions, objects, and methods for the particle transport problem. The transport problem is briefly described, as well as the current status and algorithms in MC++ for solving the transport equation. The alpha version of the POOMA class library is also discussed, along with the implementation of the transport solution algorithms using POOMA. Finally, a simple test problem is defined and performance and physics results from this problem are discussed on a variety of platforms.

Indicator strip and portable instrument technologies for determining nitroesters or moisture in combustible cartridge cases  

Science Conference Proceedings (OSTI)

The sometimes large round-to-round variability observed in accelerated environmental testing, plus difficulties in quantifying the environmental histories of a given round suggest the need for nondestructive rapid tests of munitions to supplement lifetime prediction models in quality assurance of munitions. Technologies are being developed for reagent strips which can be affixed to rounds and which will visually indicate the presence and extent of nitroester migration by a visible color change. A solid state adaptation of a modified Griess reagent develops a red-purple color in the presence of nitroesters. Performance of current designs tested in the laboratory suggest a short-term (ca. one month) single usage. Dielectric capacitance is a promising means for rapid, nondestructive moisture determinations using a portable battery-powered instrument. Laboratory studies with a modified, inexpensive, commercial device have demonstrated fast (a few seconds) detection of case wall moisture content.

Portable sensor for hazardous waste. Final report, March 31, 1995--May 31, 1997  

SciTech Connect

This report summarizes accomplishments for the second phase of a 5-year program designed to develop a portable monitor for sensitive hazardous waste detection. The approach is to excite atomic fluorescence by the technique of Spark-Induced Breakdown Spectroscopy (SIBS). The principal goals for this second phase of the program were to demonstrate sensitive detection of additional species, both RCRA metals (Sb, Be, Cd, Cr, Pb, As, Hg) and radionuclides (U, Th, Tc); to identify potential applications and develop instrument component processes, including, sample collection and excitation, measurement and test procedures, and calibration procedures; and to design a prototype instrument. Successful completion of these task results in being able to fabricate and field test a prototype of the instrument during the program`s third phase.

Estimates of neutron reaction rates in three portable He-3 proportional counters  

SciTech Connect

The goal of this study is to obtain Monte Carlo estimates of neutron reaction rates for the {sup 3}He(n,p){sup 3}H reaction in two portable He-3 proportional counters in several configurations to quantify contributions from the environment, and optimize the tube characteristics. The smallest tube (0.5-inch diameter, 2-inch long, P = 10 atm) will not meet requirements. The largest tube (1-inch diameter, 4-inch long, P = 6 or 10 atm) will meet requirements and the tube length could be decreased to 2-inch at 6 atm and 1-inch at 10 atm. The 'medium' tube (3/4-inch diameter, 2-inch long, P = 10 atm) will meet requirements for the parallelepiped body, but will not for the cylindrical body.

Interpolator for numerically controlled machine tools  

DOE Patents (OSTI)

A digital differential analyzer circuit is provided that depending on the embodiment chosen can carry out linear, parabolic, circular or cubic interpolation. In the embodiment for parabolic interpolations, the circuit provides pulse trains for the X and Y slide motors of a two-axis machine to effect tool motion along a parabolic path. The pulse trains are generated by the circuit in such a way that parabolic tool motion is obtained from information contained in only one block of binary input data. A part contour may be approximated by one or more parabolic arcs. Acceleration and initial velocity values from a data block are set in fixed bit size registers for each axis separately but simultaneously and the values are integrated to obtain the movement along the respective axis as a function of time. Integration is performed by continual addition at a specified rate of an integrand value stored in one register to the remainder temporarily stored in another identical size register. Overflows from the addition process are indicative of the integral. The overflow output pulses from the second integration may be applied to motors which position the respective machine slides according to a parabolic motion in time to produce a parabolic machine tool motion in space. An additional register for each axis is provided in the circuit to allow "floating" of the radix points of the integrand registers and the velocity increment to improve position accuracy and to reduce errors encountered when the acceleration integrand magnitudes are small when compared to the velocity integrands. A divider circuit is provided in the output of the circuit to smooth the output pulse spacing and prevent motor stall, because the overflow pulses produced in the binary addition process are spaced unevenly in time. The divider has the effect of passing only every nth motor drive pulse, with n being specifiable. The circuit inputs (integrands, rates, etc.) are scaled to give exactly n times the desired number of pulses out, in order to compensate for the divider.

Technology: Machine and its interpretation in architecture  

E-Print Network (OSTI)

The objective of this study is to develop a comprehensive theory for the relationship between architecture and technology and to examine the interpretation of technology when it is applied to architecture. In architecture, 'art and craft' and 'doing and saying (presentation)' are closely interwoven. It is sensitive to the external environment in nature, and its boundary has been actively changed. The nineteenth century brought the sudden alteration of culture with the collaboration between science and its applied means or knowledge - "technology". Subsequently, in the twentieth century, the new culture has transformed our normal life style and we can perceive the development of civilization sensuously. The machine as a product of industrial civilization and the symbol of technology has generated new meanings and tradition in tune with this historical trend. Therefore, this study will center on the concept 'technology', which is one of the conspicuous factors in the formation of modern architecture, and it will investigate the relationship between technology and architecture.

Design studies of mirror machine reactors  

SciTech Connect

An overview is presented of a mirror fusion reactor design study. The general methodology used in the study is discussed, the reactor is described, and some design alternatives to the present approach are enumerated. The system chosen for this design study is a mirror machine with direct conversion using D- T fuel. The nominal power output is 200 MW. The coil geometry is the Yin Yang, minimum B with a vacuum mirror ratio of 3. The coil is of particular utility because of its simple conductor shapes and because the two separate conductors, by proper B-field biasing, allow the charged particles to escape preferentially through one mirror only and through a relatively small window'' of that mirror. This is necessary for direct converter economy. (auth)

Applying Alpha-Channeling to Mirror Machines  

SciTech Connect

The ?-channeling effect entails the use of radio-frequency waves to expel and cool high-energetic ?- particles born in a fusion reactor; the device reactivity can then be increased even further by redirecting the extracted energy to fuel ions. Originally proposed for tokamaks, this technique has also been shown to benefi t open-ended fusion devices. Here, the fundamental theory and practical aspects of ?- channeling in mirror machines are reviewed, including the influence of magnetic field inhomogeneity and the effect of a finite wave region on the ?-channeling mechanism. For practical implementation of the ? -channeling effect in mirror geometry, suitable contained weakly-damped modes are identifi ed. In addition, the parameter space of candidate waves for implementing the ? -channeling effect can be signi cantly extended through the introduction of a suitable minority ion species that has the catalytic effect of moderating the transfer of power from the ?-channeling wave to the fuel ions.

Radioactive air emissions notice of construction portable temporary radioactive air emission units - August 1998  

SciTech Connect

This notice of construction (NOC) requests a categorical approval for construction and operation of three types of portable/temporary radionuclide airborne emission units (PTRAEUs). These three types are portable ventilation-filter systems (Type I), mobile sample preparation facilities (Type II), and mobile sample screening and analysis facilities (Type 111). Approval of the NOC application is intended to allow construction and operation of the three types of PTRAEUs without prior project-specific approval. Environmental cleanup efforts on the Hanford Site often require the use of PTRAEUs. The PTRAEUs support site characterization activities, expedited response actions (ERAs), sampling and monitoring activities, and other routine activities. The PTRAEUs operate at various locations around the Hanford Site. Radiation Air Emissions Program, Washington Administrative Code (WAC) 246-247, requires that the Washington State Department of Health (WDOH) be notified before construction of any new emission that would release airborne radioactivity. The WDOH also must receive notification before any modification of an existing source. This includes changes in the source term or replacement of emission control equipment that might significantly contribute to the offsite maximum dose from a licensed facility. During site characterization activities, ERAs, sampling and monitoring activities, and other routine activities, the PTRAEUs might require startup immediately. The notification period hampers efforts to complete such activities in an effective and timely manner. Additionally, notification is to be submitted to the WDOH when the PTRAEUs are turned off. The U.S. Department of Energy, Richland Operations Office (DOE-RL) potentially could generate several notifications monthly. The WDOH would be required to review and provide approval on each NOC as well as review the notices of discontinued sources. The WDOH regulation also allows facilities the opportunity to request a single categorical license that identifies limits and conditions of operations for similar multipurpose temporary and or portable emission units. The DOE-RL will submit annually to the WDOH a report summarizing the log books maintained on the individual PTRAEUs that are used during the reporting period. The report will supply information needed to ensure compliance with the condition of operations. The NOC includes a general description of the three types of PTRAEUs, tracking mechanisms, emissions control systems, and radioactivity handling limits (RHLs) for the PTR4EUs. The NOC is based on hypothetical data to demonstrate how emission estimates could be calculated. Tracking will be performed and monitoring will be conducted for compliance with both federal and state regulations. Type I units will use a single isotope based on a calculated RHL (source term) to determine emissions, dose, and monitoring requirements. Type I1 and 111 units will use field data and process knowledge to determine emissions, dose, and monitoring requirements. New PTRAEUs that conform to any of the three types of PTRAEUs described in this application will be added to the next annual report after the units are placed in service. New PTRAEUs, which do not conform to any of the three types of PTRAEUs described in this application, will require approval on an individual basis by the WDOH before startup.

LTC vacuum blasting machine (metal): Baseline report  

SciTech Connect

The LTC coating removal technology was tested and is being evaluated at Florida International University (FIU) as a baseline technology. In conjunction with evaluation of efficiency and cost, this report covers the evaluation conducted for safety and health issues. It is a commercially available technology and has been used for various projects at locations throughout the country. The LTC coating removal system consisted of several hand tools, a Roto Peen scaler, and a needlegun. They are designed to remove coatings from steel, concrete, brick, and wood. These hand tools are used with the LTC PTC-6 vacuum system to capture dust and debris as removal of the coating takes place. The safety and health evaluation during the testing demonstration focused on two main areas of exposure: dust and noise. The dust exposure was minimal but noise exposure was significant. Further testing for each exposure is recommended because of the environment where the testing demonstration took place. It is feasible that the dust and noise levels will be higher in an enclosed operating environment of different construction. In addition, other areas of concern found were arm-hand vibration, whole-body vibration, ergonomics, heat stress, tripping hazards, electrical hazards, machine guarding, and lockout/tagout.

LTC vacuum blasting machine (concrete): Baseline report  

SciTech Connect

The LTC shot blast technology was tested and is being evaluated at Florida International University (FIU) as a baseline technology. In conjunction with FIU`s evaluation of efficiency and cost, this report covers the evaluation conducted for safety and health issues. It is a commercially available technology and has been used for various projects at locations throughout the country. The LTC 1073 Vacuum Blasting Machine uses a high-capacity, direct-pressure blasting system which incorporates a continuous feed for the blast media. The blast media cleans the surface within the contained brush area of the blast. It incorporates a vacuum system which removes dust and debris from the surface as it is blasted. The safety and health evaluation during the testing demonstration focused on two main areas of exposure: dust and noise. Dust exposure during maintenance activities was minimal, but due to mechanical difficulties dust monitoring could not be conducted during operation. Noise exposure was significant. Further testing for each of these exposures is recommended because of the outdoor environment where the testing demonstration took place. This may cause the results to be inaccurate. It is feasible that the dust and noise levels will be higher in an enclosed environment. In addition, other safety and health issues found were ergonomics, heat stress, tripping hazards, electrical hazards, lockout/tagout, and arm-hand vibration.

Classification of Images Using Support Vector Machines  

E-Print Network (OSTI)

Support Vector Machines (SVMs) are a relatively new supervised classification technique to the land cover mapping community. They have their roots in Statistical Learning Theory and have gained prominence because they are robust, accurate and are effective even when using a small training sample. By their nature SVMs are essentially binary classifiers, however, they can be adopted to handle the multiple classification tasks common in remote sensing studies. The two approaches commonly used are the One-Against-One (1A1) and One-Against-All (1AA) techniques. In this paper, these approaches are evaluated in as far as their impact and implication for land cover mapping. The main finding from this research is that whereas the 1AA technique is more predisposed to yielding unclassified and mixed pixels, the resulting classification accuracy is not significantly different from 1A1 approach. It is the authors conclusions that ultimately the choice of technique adopted boils down to personal preference and the uniquene...

Muon Collider Machine-Detector Interface  

SciTech Connect

In order to realize the high physics potential of a Muon Collider (MC) a high luminosity of {mu}{sup +}{mu}{sup -}-collisions at the Interaction Point (IP) in the TeV range must be achieved ({approx}10{sup 34} cm{sup -2}s{sup -1}). To reach this goal, a number of demanding requirements on the collider optics and the IR hardware - arising from the short muon lifetime and from relatively large values of the transverse emittance and momentum spread in muon beams that can realistically be obtained with ionization cooling should be satisfied. These requirements are aggravated by limitations on the quadrupole gradients as well as by the necessity to protect superconducting magnets and collider detectors from muon decay products. The overall detector performance in this domain is strongly dependent on the background particle rates in various sub-detectors. The deleterious effects of the background and radiation environment produced by the beam in the ring are very important issues in the Interaction Region (IR), detector and Machine-Detector Interface (MDI) designs. This report is based on studies presented very recently.

Toward Abstracting the Communication Intent in Applications to Improve Portability and Productivity  

SciTech Connect

Programming with communication libraries such as the Message Passing Interface (MPI) obscures the high-level intent of the communication in an application and makes static communication analysis difficult to do. Compilers are unaware of communication libraries specifics, leading to the exclusion of communication patterns from any automated analysis and optimizations. To overcome this, communication patterns can be expressed at higher-levels of abstraction and incrementally added to existing MPI applications. In this paper, we propose the use of directives to clearly express the communication intent of an application in a way that is not specific to a given communication library. Our communication directives allow programmers to express communication among processes in a portable way, giving hints to the compiler on regions of computations that can be overlapped with communication and relaxing communication constraints on the ordering, completion and synchronization of the communication imposed by specific libraries such as MPI. The directives can then be translated by the compiler into message passing calls that efficiently implement the intended pattern and be targeted to multiple communication libraries. Thus far, we have used the directives to express point-to-point communication patterns in C, C++ and Fortran applications, and have translated them to MPI and SHMEM.

Portable NDA equipment for enrichment measurements for the HEU transparency program  

SciTech Connect

In October 1996, the Department of Energy (DOE) and MINATOM agreed to use portable non-destructive assay (NDA) equipment to measure the {sup 235}U enrichment of material subject to the HEU Transparency agreement. A system based on the ''enrichment meter'' method and high-purity germanium (HPGe) detectors had been previously developed for this application. Instead, sodium iodide (NaI) detectors were chosen to measure {sup 235}U enrichment because HPGe systems might reveal sensitive information. Although the accuracy of the NaI systems is less than an HPGe system, it still satisfies the transparency requirements. The equipment consists of a collimated NaI detector, a Canberra Inspector Multi-channel Analyzer, and a laptop computer. The units have been used to confirm the enrichment of material at Russian facilities since January 1997. This paper compares the performance of the NaI systems with the HPGe system and discusses some significant differences.

An Efficient Battery-Aware Task Scheduling Methodology for Portable RC Platforms and Applications  

E-Print Network (OSTI)

Abstract. In this paper we present a simple yet efficient methodology for battery-aware task execution on FPGAs in portable Reconfigurable Computing (RC) platforms. We divide the reconfigurable area on an FPGA into several fixed reconfigurable slots called Configurable Tiles. We then schedule real-time tasks onto these tiles. Various schedules using different number of tiles are calculated off-line. These schedules along with their execution times are then sent to a run-time scheduler which dynamically decides, which schedule is the most battery efficient. By varying the number of tiles used for scheduling tasks, we can vary the battery usage and lifetime. We tested the methodology by running it on several different task graph structures and sizes, and report an average of 14 % and as high as 21%, less battery capacity used, as compared to nonoptimal execution. Finally, we present a case study where we implement a real-time face recognition algorithm on the iPACE-V1 [6] platform using the proposed methodology and observed 1.3 to 3.3 times improvement in battery life-time. 1

A portable vacuum hammer seismic source for use in tunnel environments  

SciTech Connect

Concern for the measurement of seismic refraction velocities in tunnel areas where cables, construction features, and other sensitive structures render the use of dynamite sources unwise, resulted in the design of a vacuum-driven impact system utilizing a 43-kg (94-lb) weight in a 2-m (6.5-ft) tube. The system is portable, quickly assembled and disassembled, and requires only standard electrical power, an air pressure supply, and a laboratory vacuum pump to operate. The maximum weight of any component is 84 kg (185 lb), the remaining components being significantly lighter. Tests in volcanic rock tunnels in Rainier Mesa at the Nevada Test Site indicate maximum energy generated by the system is in the SV wave. When the system was employed at angles other than vertical, a polarized SH mode was also observed. The hammer was used to obtain velocities in an in-hole survey in a 138-m horizontal hole drilled behind the flat face of the Red Hot chamber after the Red Hot nuclear detonation. A large decrease was observed in compressional velocity compared with pre-event values. Because 20 years have elapsed since the explosion, one cannot separate the effect of ground shock on lowering the velocity from possible effects of destressing around adjacent underground openings over this period.

A highly portable, rapidly deployable system for eddy covariance measurements of CO2 fluxes  

DOE Green Energy (OSTI)

To facilitate the study of flux heterogeneity within a region, the authors have designed, built, and field-tested a highly portable, rapidly deployable, eddy covariance CO{sub 2} flux measurement system. The system is built from off-the-shelf parts and was assembled at a minimal cost. The unique combination of features of this system allow for a very rapid deployment with a minimal number of field personnel. The system is capable of making high precision, unattended measurements of turbulent CO{sub 2} fluxes, latent heat (LE) fluxes, sensible heat fluxes (H), and momentum transfer fluxes. In addition, many of the meteorological and ecosystem variables necessary for quality control of the fluxes and for running ecosystem models are measured. A side-by-side field comparison of the system at a pair of established AmeriFlux sites has verified that, for single measurements, the system is capable of CO{sub 2} flux accuracy of about {+-} 1.2 {micro}mole/m{sup 2}/sec, LE flux accuracy of about {+-} 15 Watts/m{sup 2}, H flux accuracy of about {+-} 7 Watts/m{sup 2}, and momentum transfer flux accuracy of about {+-} 11 gm-m/sec/sec. System deployment time is between 2 and 4 hours by a single person. The system was measured to draw between 30 and 35 Watts of power and may be run from available line power, storage batteries, or solar panels.

Integrated Mirco-Machined Hydrogen Gas Sensors  

DOE Green Energy (OSTI)

The widespread use of hydrogen as both an industrial process gas and an energy storage medium requires fast, selective detection of hydrogen gas. This report discusses the development of a new type of solid-state hydrogen gas sensor that couples novel metal hydride thin films with a MEMS (Micro-Electro-Mechanical System) structure known as a micro-hotplate. In this project, Micro-hotplate structures were overcoated with engineered multilayers that serve as the active hydrogen-sensing layer. The change in electrical resistance of these layers when exposed to hydrogen gas was the measured sensor output. This project focused on achieving the following objectives: (1) Demonstrating the capabilities of micro-machined H2 sensors; (2) Developing an understanding of their performance; (3) Critically evaluating the utility and viability of this technology for life safety and process monitoring applications. In order to efficiently achieve these objectives, the following four tasks were identified: (1) Sensor Design and Fabrication; (2) Short Term Response Testing; (3) Long Term Behavior Investigation; (4) Systems Development. Key findings in the project include: The demonstration of sub-second response times to hydrogen; measured sensitivity to hydrogen concentrations below 200 ppm; a dramatic improvement in the sensor fabrication process and increased understanding of the processing properties and performance relationships of the devices; the development of improved sensing multilayers; and the discovery of a novel strain based hydrogen detection mechanism. The results of this program suggest that this hydrogen sensor technology has exceptional potential to meet the stringent demands of life safety applications as hydrogen utilization and infrastructure becomes more prevalent.

Machine to machine (M2M) technology in demand responsive commercial buildings  

SciTech Connect

Machine to Machine (M2M) is a term used to describe the technologies that enable computers, embedded processors, smart sensors, actuators and mobile devices to communicate with one another, take measurements and make decisions--often without human intervention. M2M technology was applied to five commercial buildings in a test. The goal was to reduce electric demand when a remote price signal rose above a predetermine price. In this system, a variable price signal was generated from a single source on the Internet and distributed using the meta-language, XML (Extensible Markup Language). Each of five commercial building sites monitored the common price signal and automatically shed site-specific electric loads when the price increased above predetermined thresholds. Other than price signal scheduling, which was set up in advance by the project researchers, the system was designed to operate without human intervention during the two-week test period. Although the buildings responded to the same price signal, the communication infrastructures used at each building were substantially different. This study provides an overview of the technologies used at each building site, the price generator/server, and each link in between. Network architecture, security, data visualization and site-specific system features are characterized. The results of the test are discussed, including: functionality at each site, measurement and verification techniques, and feedback from energy managers and building operators. Lessons learned from the test and potential implications for widespread rollout are provided.

Homopolar machine for reversible energy storage and transfer systems  

DOE Patents (OSTI)

A homopolar machine designed to operate as a generator and motor in reversibly storing and transferring energy between the machine and a magnetic load coil for a thermo-nuclear reactor. The machine rotor comprises hollow thin-walled cylinders or sleeves which form the basis of the system by utilizing substantially all of the rotor mass as a conductor thus making it possible to transfer substantially all the rotor kinetic energy electrically to the load coil in a highly economical and efficient manner. The rotor is divided into multiple separate cylinders or sleeves of modular design, connected in series and arranged to rotate in opposite directions but maintain the supply of current in a single direction to the machine terminals. A stator concentrically disposed around the sleeves consists of a hollow cylinder having a number of excitation coils each located radially outward from the ends of adjacent sleeves. Current collected at an end of each sleeve by sleeve slip rings and brushes is transferred through terminals to the magnetic load coil. Thereafter, electrical energy returned from the coil then flows through the machine which causes the sleeves to motor up to the desired speed in preparation for repetition of the cycle. To eliminate drag on the rotor between current pulses, the brush rigging is designed to lift brushes from all slip rings in the machine.

Online Load Balancing on Unrelated Machines with Startup Costs  

E-Print Network (OSTI)

Motivated by applications in energy-efficient scheduling in data centers, Khuller, Li, and Saha introduced the {\\em machine activation} problem as a generalization of the classical optimization problems of set cover and load balancing on unrelated machines. In this problem, a set of $n$ jobs have to be distributed among a set of $m$ (unrelated) machines, given the processing time of each job on each machine, where each machine has a startup cost. The goal is to produce a schedule of minimum total startup cost subject to a constraint $\\bf L$ on its makespan. While Khuller {\\em et al} considered the offline version of this problem, a typical scenario in scheduling is one where jobs arrive online and have to be assigned to a machine immediately on arrival. We give an $(O(\\log (mn)\\log m), O(\\log m))$-competitive randomized online algorithm for this problem, i.e. the schedule produced by our algorithm has a makespan of $O({\\bf L} \\log m)$ with high probability, and a total expected startup cost of $O(\\log (mn)\\lo...

Palm top plasma focus device as a portable pulsed neutron source  

SciTech Connect

Development of a palm top plasma focus device generating (5.2 {+-} 0.8) Multiplication-Sign 10{sup 4} neutrons/pulse into 4{pi} steradians with a pulse width of 15 {+-} 3 ns is reported for the first time. The weight of the system is less than 1.5 kg. The system comprises a compact capacitor bank, a triggered open air spark gap switch, and a sealed type miniature plasma focus tube. The setup is around 14 cm in diameter and 12.5 cm in length. The energy driver for the unit is a capacitor bank of four cylindrical commercially available electrolytic capacitors. Each capacitor is of 2 {mu}F capacity, 4.5 cm in diameter, and 9.8 cm in length. The cost of each capacitor is less than US$ 10. The internal diameter and the effective length of the plasma focus unit are 2.9 cm and 5 cm, respectively. A DC to DC converter power supply powered by two rechargeable batteries charges the capacitor bank to the desired voltage and also provides a trigger pulse of -15 kV to the spark gap. The maximum energy of operation of the device is 100 J (8 {mu}F, 5 kV, 59 kA) with deuterium gas filling pressure of 3 mbar. The neutrons have also been produced at energy as low as 36 J (3 kV) of operation. The neutron diagnostics are carried out with a bank of {sup 3}He detectors and with a plastic scintillator detector. The device is portable, reusable, and can be operated for multiple shots with a single gas filling.

The Kelastic variable wall mining machine. Interim final report  

SciTech Connect

This machine cuts coal along a longwall face extending up to 500 feet by a rotating auger with bits. The machine also transports the coal that is cut acting as screw conveyor. By virtue of an integral shroud comprising part of the conveyor the machine is also amenable to a separation of the zones where men work from air being contaminated by dust and methane gas by the cutting action. Beginning as single intake air courses, the air separates at the working section where one split provides fresh air to the Occupied Zone (OZ) for human needs and the other split purges and carries away dust and methane from face fragmentation in the Cutting Zone (CZ). The attractiveness of the Variable Wall Mining Machine is that it addresses the limitations of current longwall mining equipment: it can consistently out-produce continuous mining machines and most longwall shearing machines. It also is amenable to configuring an environment, the dual-duct system, where the air for human breathing is separated from dust-laden ventilating air with methane mixtures. The objective of the research was to perform a mathematical and experimental study of the interrelationships of the components of the system so that a computer model could demonstrate the workings of the system in an animation program. The analysis resulted in the compilation of the parameters for three different configurations of a dual aircourse system of ventilating underground mines. In addressing the goal of an inherently safe mining system the dual-duct adaptation to the Variable Wall Mining Machine appears to offer the path to solution. The respirable dust problem is solvable; the explosive dust problem is nearly solvable; and the explosive methane problem can be greatly reduced. If installed in a highly gassy mine, the dual duct models would also be considerably less costly.

DOE Patents (OSTI)

A holographic security label and automated reading machine for marking and subsequently authenticating any object such as an identification badge, a pass, a ticket, a manufactured part, or a package is described. The security label is extremely difficult to copy or even to read by unauthorized persons. The system comprises a holographic security label that has been created with a coded reference wave, whose specification can be kept secret. The label contains information that can be extracted only with the coded reference wave, which is derived from a holographic key, which restricts access of the information to only the possessor of the key. A reading machine accesses the information contained in the label and compares it with data stored in the machine through the application of a joint transform correlator, which is also equipped with a reference hologram that adds additional security to the procedure.

Finish machining operations contribute the majority of the costs associated with fabricating high quality ceramic products. These components are typically used in harsh environments such as diesel engines, the defense industry, and automotive applications. The required finishing operations involve a variety of technology areas including process controls, process analysis, product certification, etc. and are not limited only to component grinding methods. The broad range of manufacturing problem solving expertise available in Oak Ridge provided resources that were far beyond what is available to the Coors manufacturing sites. Coors contributed equipment, such as the computer controls and part handling mechanisms associated with a state-of-the-art inspection machine plus operation-specific experience base. In addition, addressing these challenging tasks enabled Oak Ridge personnel to maintain familarity with rapidly advancing technologies, such as those associated with machine vision equipment, process monitoring techniques, and computer control systems.

Aspects of surface generation in orthogonal ultraprecision machining  

SciTech Connect

The depth of the plastically deformed layer at the workpiece surface which resulted in the orthogonal ultraprecision machining of Cu over the range of uncut chip thicknesses of 0.01-10 {mu}m was investigated. Two tools with the same nominal geometry but with differing edge geometries were used to machine both Te-Cu and fine grain Cu. Tool edge geometries were characterized by atomic force microscopy, taking into account the AFM cantilever tip radius. Magnitudes of the measured depths appear to be consistent with values reported in the literature and those arrived at by simple analyses.

Control system for an interior permanent magnet synchronous machine  

DOE Patents (OSTI)

A high performance, fully operational, four-quadrant control scheme is used in an interior permanent magnet synchronous machine. The machine operates smoothly with full performance in the constant-torque region as well as in the flux-weakening, constant-power region in both directions of motion. The transition between the constant-torque and constant-power regions is very smooth under all conditions of operation. Control in the constant-torque region is based on a vector or field-oriented technique, with the direct-axis aligned with the total stator flux, whereas constant-power region control is accomplished by orientation of the torque angle of the impressed square-wave voltage through the feedforward vector rotator. In a preferred embodiment, the control system employs a digital distributed microcomputer controller arrangement which relies upon various precisely estimated feedback signals, such as torque, flux, etc. The control scheme includes an outer torque control loop primarily for traction type applications, but also contemplates speed and position control loops for various industrial drives. A 70 hp drive system using a Neodymium-Iron-Boron permanent magnet machine and transistor pulse width modulating inverter has been designed and successfully tested. This control scheme also has application in controlling surface permanent magnet machines. 16 figs.

Energy management for hypervisor-based virtual machines  

E-Print Network (OSTI)

Current approaches to power management are based on operating systems with full knowledge of and full control over the underlying hardware; the distributed nature of multi-layered virtual machine environments renders such approaches insufficient. In this paper, we present a novel framework for energy management in modular, multi-layered operating system structures. The framework provides a unified model to partition and distribute energy, and mechanisms for energy-aware resource accounting and allocation. As a key property, the framework explicitly takes the recursive energy consumption into account, which is spent, e.g., in the virtualization layer or subsequent driver components. Our prototypical implementation targets hypervisor-based virtual machine systems and comprises two components: a host-level subsystem, which controls machine-wide energy constraints and enforces them among all guest OSes and service components, and, complementary, an energy-aware guest operating system, capable of fine-grained applicationspecific energy management. Guest level energy management thereby relies on effective virtualization of physical energy effects provided by the virtual machine monitor. Experiments with CPU and disk devices and an external data acquisition system demonstrate that our framework accurately controls and stipulates the power consumption of individual hardware devices, both for energy-aware and energyunaware guest operating systems. 1
