Spatial Feature Evaluation for Aerial Scene Analysis  

Science Conference Proceedings (OSTI)

High-resolution aerial images are becoming more readily available, which drives the demand for robust, intelligent and efficient systems to process increasingly large amounts of image data. However, automated image interpretation still remains a challenging problem. Robust techniques to extract and represent features to uniquely characterize various aerial scene categories is key for automated image analysis. In this paper we examined the role of spatial features to uniquely characterize various aerial scene categories. We studied low-level features such as colors, edge orientations, and textures, and examined their local spatial arrangements. We computed correlograms representing the spatial correlation of features at various distances, then measured the distance between correlograms to identify similar scenes. We evaluated the proposed technique on several aerial image databases containing challenging aerial scene categories. We report detailed evaluation of various low-level features by quantitatively measuring accuracy and parameter sensitivity. To demonstrate the feature performance, we present a simple query-based aerial scene retrieval system.

Adaptation of Lighting Styles from Traditional Paintings to Computer Generated Scenes  

E-Print Network (OSTI)

Image making using Computer Graphics has become extremely popular. Great advances in computer graphics have led to an increasing number of people using this medium. But Computer Graphics on its own is not art unless art principles are applied to it, as is the case with any other art medium. Studying art principles used in traditional paintings is an invaluable way of learning how to create images that tell a story, look believable, evoke appropriate emotions, and remain aesthetically alluring too. With that motivation in mind, a visual analysis of paintings of John Register, Jules Breton and Chris Peters was conducted to better understand their styles. Two paintings by each of the three artists were then selected for an in depth study and based on those, computer generated renderings were produced. Inspired by each artist's style, digital scenes were modeled, lit and rendered using 3D authoring tools. The final rendered images exhibit the lighting style unique to each of the three artists.

Aerial Scene Recognition using Efficient Sparse Representation  

SciTech Connect

Advanced scene recognition systems for processing large volumes of high-resolution aerial image data are in great demand today. However, automated scene recognition remains a challenging problem. Efficient encoding and representation of spatial and structural patterns in the imagery are key in developing automated scene recognition algorithms. We describe an image representation approach that uses simple and computationally efficient sparse code computation to generate accurate features capable of producing excellent classification performance using linear SVM kernels. Our method exploits unlabeled low-level image feature measurements to learn a set of basis vectors. We project the low-level features onto the basis vectors and use simple soft threshold activation function to derive the sparse features. The proposed technique generates sparse features at a significantly lower computational cost than other methods~\\cite{Yang10, newsam11}, yet it produces comparable or better classification accuracy. We apply our technique to high-resolution aerial image datasets to quantify the aerial scene classification performance. We demonstrate that the dense feature extraction and representation methods are highly effective for automatic large-facility detection on wide area high-resolution aerial imagery.

Synthetic IR Scene Simulation of Air-borne Targets  

E-Print Network (OSTI)

IR scenes of high fidelity are needed to support the development and testing of various target detection and tracking techniques. It is impractical to test detection and tracking algorithms under all conceivable conditions. Therefore, to test the effectiveness of detection and tracking algorithms under variety of scenarios, synthetic IR scenes are generated. For air-borne targets, the presence of clouds plays an important role, since they affect most IR sensors. We propose, a mod- ification of original Gardner's Method [3], in order to generate clouds of richer spectral content. We also ex- plore an algorithm based on self-similarity [5] for cloud texture generation. Synthetic IR cloud images generated by our scene simulation software are radiometrically accurate and have typical cloud texture variations. We use Modtran J.O for radiometric calculation and VRML (Virtual Reality Modeling Language) for scene rendering.

Ray tracing a three dimensional scene using a grid  

DOE Patents (OSTI)

Ray tracing a three-dimensional scene using a grid. One example embodiment is a method for ray tracing a three-dimensional scene using a grid. In this example method, the three-dimensional scene is made up of objects that are spatially partitioned into a plurality of cells that make up the grid. The method includes a first act of computing a bounding frustum of a packet of rays, and a second act of traversing the grid slice by slice along a major traversal axis. Each slice traversal includes a first act of determining one or more cells in the slice that are overlapped by the frustum and a second act of testing the rays in the packet for intersection with any objects at least partially bounded by the one or more cells overlapped by the frustum.

SAMPEG, a Scene Adaptive Parallel MPEG-2 Software Encoder  

E-Print Network (OSTI)

This paper presents a fully software-based MPEG-2 encoder architecture, which uses scene-change detection to optimize the Group-of-Picture (GOP) structure for the actual video sequence. This feature enables easy, lossless edit cuts at scene-change positions and it also improves overall picture quality by providing good reference frames for motion prediction. Another favourable aspect is the high coding speed obtained, because the encoder is based on a novel concept for parallel MPEG coding on SMP machines. This concept allows the use of advanced frame-based coding algorithms for motion estimation and adaptive quantization, thereby enabling high-quality software encoding in real-time. Our proposal can be combined with the conventional parallel computing approach on slice basis, to further improve parallelization eciency. The concepts in the current SAMPEG implementation for MPEG-2 are directly applicable to MPEG-4 encoders.

Identifying technology barriers in adapting a state-of-the-art gas turbine for IGCC applications and an experimental investigation of air extraction schemes for IGCC operations. Final report  

SciTech Connect

Under contracted work with Morgantown Energy Technology Center, Clemson University, the prime contractor, and General Electric (GE) and CRSS, the subcontractors, made a comprehensive study in the first phase of research to investigate the technology barriers of integrating a coal gasification process with a hot gas cleanup scheme and the state-of-the-art industrial gas turbine, the GE MS-7001F. This effort focused on (1) establishing analytical tools necessary for modeling combustion phenomenon and emissions in gas turbine combustors operating on multiple species coal gas, (2) estimates the overall performance of the GE MS-7001F combined cycle plant, (3) evaluating material issues in the hot gas path, (4) examining the flow and temperature fields when air extraction takes place at both the compressor exit and at the manhole adjacent to the combustor, and (5) examining the combustion/cooling limitations of such a gas turbine by using 3-D numerical simulation of a MS-7001F combustor operated with gasified coal. In the second phase of this contract, a 35% cool flow model was built similar to GE`s MS-7001F gas turbine for mapping the flow region between the compressor exit and the expander inlet. The model included sufficient details, such as the combustor`s transition pieces, the fuel nozzles, and the supporting struts. Four cases were studied: the first with a base line flow field of a GE 7001F without air extraction; the second with a GE 7001F with air extraction; and the third and fourth with a GE 7001F using a Griffith diffuser to replace the straight wall diffuser and operating without air extraction and with extraction, respectively.

Segmenting Simply Connected Moving Objects in a Static Scene  

E-Print Network (OSTI)

A new segmentation algorithm is derived, based on an object-background probability estimate exploiting the experimental fact that the statistics of local image derivatives show a Laplacian distribution. The objects' simply connectedness is included directly into the probability estimate and leads to an iterative optimization approach that can be implemented efficiently. This new approach avoids early thresholding, explicit edge detection, motion analysis, and grouping. Contribution type: Correspondence 1 This work was supported by the consortium VISAGE and KWF grant No. 2440.1 1 Introduction In many object recognition applications the objects of interest are moving whereas the background is static or can be stabilized [1, 2]. Motion segmentation can enormously simplify, subsequent object recognition steps. Therefore, detecting and segmenting moving objects in a static scene is an important computer vision task. In recent years a number of different approaches have been proposed for...

Learning Scene Categories from High Resolution Satellite Image for Aerial Video Analysis  

SciTech Connect

Automatic scene categorization can benefit various aerial video processing applications. This paper addresses the problem of predicting the scene category from aerial video frames using a prior model learned from satellite imagery. We show that local and global features in the form of line statistics and 2-D power spectrum parameters respectively can characterize the aerial scene well. The line feature statistics and spatial frequency parameters are useful cues to distinguish between different urban scene categories. We learn the scene prediction model from highresolution satellite imagery to test the model on the Columbus Surrogate Unmanned Aerial Vehicle (CSUAV) dataset ollected by high-altitude wide area UAV sensor platform. e compare the proposed features with the popular Scale nvariant Feature Transform (SIFT) features. Our experimental results show that proposed approach outperforms te SIFT model when the training and testing are conducted n disparate data sources.

Process As Art Process As Art and Other Misconceptions  

E-Print Network (OSTI)

What is a process? A set of activities that turn inputs into outputs. What is a good process? A process that does what it is supposed to do when it is supposed to do it, reliably. What is a great process? One that is effective and optimally efficient. Are there activities that are not amenable to process? Some think so, we think not. In our work with companies, helping them understand the value of applying process to their marketing/sales activities, we have found resistance for many reasons. These reasons include the feeling that much of what goes on in marketing is art, and therefore resistant to process management. In every case, what we have discovered is that, indeed, some activities in marketing – in reality, in many business activities – require "artists " to produce the desired output. However, that by itself does not make the output art. Van Gogh, Monet, Picasso, and others produced artart as the output of artists. Some art today is produced more mechanistically, and yet nevertheless is art. In virtually all business processes, the output desired is not art, albeit some of that output is produced by artists. That distinction is important, as evident from a recent article in the Harvard Business Review 1 that asks the question, "When Should a Process be Art, Not Science? " The authors argue, "There are

Art Directable Tornadoes  

E-Print Network (OSTI)

Tornado simulations in the visual effects industry have always been an interesting problem. Developing tools to provide more control over such effects is an important and challenging task. Current methods to achieve these effects use either particle systems or fluid simulation. Particle systems give a lot of control over the simulation but do not take into account the fluid characteristics of tornadoes. The other method which involves fluid simulation models the fluid behavior accurately but does not give control over the simulation. In this thesis, a novel method to model tornado behavior is presented. A tool based on this method was also created. The method proposed in this thesis uses a hybrid approach that combines the flexibility of particle systems while producing interesting swirling motions inherent in the fluids. The main focus of the research is on providing easy-to-use controls for art directors to help them achieve the desired look of the simulation effectively. A variety of controls is provided which include the overall shape, path, rotation, debris, surface, swirling motion, and interaction with the environment. The implementation was done in Houdini, which is a 3D animation software whose node based system allows an algorithmic approach to the problem and integrates well with the current tools. The tool allows the user to create animations that reflect the visual characteristics of real tornadoes. The usefulness of the tool was evaluated among participants who had some experience in 3D animation software. The results from the simulation and evaluation feedback reveal that the tool successfully allowed the users to create tornadoes of their choice efficiently.

Error Detection, Factorization and Correction for Multi-View Scene Reconstruction from Aerial Imagery  

SciTech Connect

Scene reconstruction from video sequences has become a prominent computer vision research area in recent years, due to its large number of applications in fields such as security, robotics and virtual reality. Despite recent progress in this field, there are still a number of issues that manifest as incomplete, incorrect or computationally-expensive reconstructions. The engine behind achieving reconstruction is the matching of features between images, where common conditions such as occlusions, lighting changes and texture-less regions can all affect matching accuracy. Subsequent processes that rely on matching accuracy, such as camera parameter estimation, structure computation and non-linear parameter optimization, are also vulnerable to additional sources of error, such as degeneracies and mathematical instability. Detection and correction of errors, along with robustness in parameter solvers, are a must in order to achieve a very accurate final scene reconstruction. However, error detection is in general difficult due to the lack of ground-truth information about the given scene, such as the absolute position of scene points or GPS/IMU coordinates for the camera(s) viewing the scene. In this dissertation, methods are presented for the detection, factorization and correction of error sources present in all stages of a scene reconstruction pipeline from video, in the absence of ground-truth knowledge. Two main applications are discussed. The first set of algorithms derive total structural error measurements after an initial scene structure computation and factorize errors into those related to the underlying feature matching process and those related to camera parameter estimation. A brute-force local correction of inaccurate feature matches is presented, as well as an improved conditioning scheme for non-linear parameter optimization which applies weights on input parameters in proportion to estimated camera parameter errors. Another application is in reconstruction pre-processing, where an algorithm detects and discards frames that would lead to inaccurate feature matching, camera pose estimation degeneracies or mathematical instability in structure computation based on a residual error comparison between two different match motion models. The presented algorithms were designed for aerial video but have been proven to work across different scene types and camera motions, and for both real and synthetic scenes.

Combining a Multithreaded Scene Graph System with a Tiled Display Environment  

SciTech Connect

This case study highlights the technical challenges of creating an application that uses a multithreaded scene graph toolkit for rendering and uses a software environment for management of tiled display systems. Scene graph toolkits simplify and streamline graphics applications by providing data management and rendering services. Software for tiled display environments typically performs device and event management by opening windows on displays, by gathering and processing input device events, and by orchestrating the execution of application rendering code. These environments serve double-duty as frameworks for creating parallel rendering applications. We explore technical issues related to interfacing scene graph systems with software that manages tiled projection systems in the context of an implementation, and formulate suggestions for the future growth of such systems.

Creating effective computer generated scene lighting using traditional film lighting techniques  

E-Print Network (OSTI)

This thesis explores the process of translating traditional cinematic lighting into the digital realm by understanding distinctly different lighting styles of three Directors of Photography. These Directors of Photography are Conrad Hall, Gregg Toland, and Zhao Fei. Digital lighting studies representative of the work of each Director of Photography were created. In these studies, the lighting in scenes done by each Director of Photography was digitally mimicked. As a result, the lighting studies provided valuable insight into the approaches of these masters of light. An animation was created to display a scene lit in the three lighting styles of each Director of Photography. The process, learned from the lighting studies, of creating three different lighting styles representative of each Director of Photography was applied to the final animation. The analysis and lighting studies of each Directors' of Photography style expedited the process of lighting the final animation in each different style. As a result, a more complex environment was effectively lit in three different cinematic styles with animated light.

Creating computer generated scene lighting in the style of Edward Hopper  

E-Print Network (OSTI)

The goal of this thesis is to study the lighting styles used in three selected Edward Hopper paintings: Morning Sun, Summer Evening, and Night Windows and to create an original, three-dimensional scene lit in a similar style. For a general understanding of the reference paintings, visual analyses were conducted before studying the lighting styles depicted in them. During the process of conducting this lighting study, the lighting styles in the three reference paintings were closely examined and digitally reproduced. The artistic inspiration gained from these three paintings and the lessons learned from the reproduction process are integrated into the creation of the original work which serves as the final project of this thesis. Consequently, the final project displays the lighting style represented in those of the reference paintings, refined by this researcherâ s own style. This study defines an approach to develop the digital lighting that can dramatically enhance the moods in realistic scenes referenced by lighting in the three Hopperâ s paintings.

Science Conference Proceedings (OSTI)

Objective was to follow the cognitive and creative processes demonstrated by student research participants as they integrated a developing knowledge of ``big`` science, as practiced at LLNL, into a personal and idiosyncratic visual, graphical, or multimedia product. The participants, all non-scientists, involved in this process, attended a series of design classes, sponsored by LLNL at the Art Center College of Design in Pasadena CA. As a result of this study, we have become interested in the possibility of similar characteristics between scientists and artists. We have also become interested in the different processes that can be used to teach science to non-scientists, so that they are able to understand and portray scientific information.

A Volume Rendering Extension for the OpenSG Scene Graph API  

E-Print Network (OSTI)

We will present the current state of our ongoing work on a simple to use, extensible and cross-platform volume rendering library. Primary target of our framework is interactive scientific visualization, but volumetric effects are also desirable in other fields of computer graphics, e.g. virtual reality applications. The framework we present is based on texture-based direct volume rendering. We apply the concept of volume shaders and demonstrate their usefulness in terms of flexibility, extensibility and adaption to new or different graphics hardware. Our framework is based on the OpenSG scene graph API, that is designed especially with multi-threading and cluster-rendering in mind, thus, it is very easy to integrate volumetric visualizations into powerful virtual reality systems.

Implementation of a Dual Containment/Surveillance System utilizing scene-change detection and radio frequency technology  

SciTech Connect

This paper will examine the implementation of scene-change detection and radio frequency technology within a Dual Containment/Surveillance (C/S) System. Additionally, this paper will examine the human performance factors in the operation of these systems. Currently, Westinghouse Savannah River Company utilizes the Continuous Item Monitoring and Surveillance System (CIMS) in the performance of Dual C/S to monitor special nuclear materials within International Atomic Energy Agency (IAEA) Safeguards and Domestic Safeguards. CIMS is comprised of the Material Monitoring System (MMS) (R), a multi-media electronic surveillance system developed by Sandia National Laboratory which incorporates the use of active seals commonly called Radio Frequency Tamper Indicating Devices (RFTIDs), NT Vision (R) as developed by Los Alamos National Laboratory, a Microsoft Windows NT (R) based operating system providing for domestic scene-change detection and the Digital Multi-Camera Optical Surveillance System (DMOS) (R) which provides scene-change detection for IAEA. Although this paper will focus on the implementation of Dual C/S utilizing the Continuous Item Monitoring and Surveillance System, the necessity for a thorough review of Safeguards and Security requirements with organizations and personnel having minimal to no prior MPC&A training will also be covered. Successful Dual C/S implementation plans must consider not only system design and failure modes, but must also be accompanied with the appropriate ''mind shift'' within operations and technical personnel. This is required to ensure completion of both physical and electronic activities, and system design changes are performed conscientiously and with full awareness of MPC&A requirements.

Scientists and artists: ""Hey! You got art in my science! You got science on my art  

SciTech Connect

The pairing of science and art has proven to be a powerful combination since the Renaissance. The combination of these two seemingly disparate disciplines ensured that even complex scientific theories could be explored and effectively communicated to both the subject matter expert and the layman. In modern times, science and art have frequently been considered disjoint, with objectives, philosophies, and perspectives often in direct opposition to each other. However, given the technological advances in computer science and high fidelity 3-D graphics development tools, this marriage of art and science is once again logically complimentary. Art, in the form of computer graphics and animation created on supercomputers, has already proven to be a powerful tool for improving scientific research and providing insight into nuclear phenomena. This paper discusses the power of pairing artists with scientists and engineers in order to pursue the possibilities of a widely accessible lightweight, interactive approach. We will use a discussion of photo-realism versus stylization to illuminate the expected beneficial outcome of such collaborations and the societal advantages gained by a non-traditional pa11nering of these two fields.

Mimbres rock art: a graphic legacy of cultural expression  

E-Print Network (OSTI)

Rock art abounds along the Mimbres River banks and drainage tributaries reflecting the rich cultural remains of the ancient Mimbres people. The Mimbres are a well established cultural group who lived in southwest New Mexico and northern Mexico from A.D. 200 and A.D. 1150. Physical remains of pithouses, pueblos, irrigation systems, artifacts, and rock art have survived the years to provide clues for contemporary understanding of this prehistoric culture and society. Knowledge of the symbolism and belief system has eluded understanding or remained sketchy as a result of examining only physical remains. Based on the hypothesis that by studying the archaeological record and the established characteristics of cultures with origins similar to those of the Mimbres, then assumptions can be made and applied to the understanding of the symbolism, purpose, and use of the rock art for the Mimbres. Specific to this study is the rock art adjacent to and within a one and one-half mile radius of the NAN Ranch Ruin. Research reveals how the rock art of the NAN Ranch Ruin connects to: 1) cultural context to other regional systems, 2) spatial context within the landscape, 3) temporal context with respect to Mimbres development, and 4) symbolic context, tying the rock art to its environment and revealing it as a living part of the universe as it fits into the world view of those who created it.

Hydrogen from biomass: state of the art and research challenges  

Science Conference Proceedings (OSTI)

The report was prepared for the International Energy Agency (IEA) Agreement on the Production and Utilization of Hydrogen, Task 16, Hydrogen from Carbon-Containing Materials. Hydrogen's share in the energy market is increasing with the implementation of fuel cell systems and the growing demand for zero-emission fuels. Hydrogen production will need to keep pace with this growing market. In the near term, increased production will likely be met by conventional technologies, such as natural gas reforming. In these processes, the carbon is converted to CO2 and released to the atmosphere. However, with the growing concern about global climate change, alternatives to the atmospheric release of CO2 are being investigated. Sequestration of the CO2 is an option that could provide a viable near-term solution. Reducing the demand on fossil resources remains a significant concern for many nations. Renewable-based processes like solar- or wind-driven electrolysis and photobiological water splitting hold great promise for clean hydrogen production; however, advances must still be made before these technologies can be economically competitive. For the near-and mid-term, generating hydrogen from biomass may be the more practical and viable, renewable and potentially carbon-neutral (or even carbon-negative in conjunction with sequestration) option. Recently, the IEA Hydrogen Agreement launched a new task to bring together international experts to investigate some of these near- and mid-term options for producing hydrogen with reduced environmental impacts. This review of the state of the art of hydrogen production from biomass was prepared to facilitate in the planning of work that should be done to achieve the goal of near-term hydrogen energy systems. The relevant technologies that convert biomass to hydrogen, with emphasis on thermochemical routes are described. In evaluating the viability of the conversion routes, each must be put in the context of the availability of appropriate feedstocks and deployment scenarios that match hydrogen to the local markets. Co-production opportunities are of particular interest for near-term deployment since multiple products improve the economics; however, co-product development is not covered in this report. Biomass has the potential to accelerate the realization of hydrogen as a major fuel of the future. Since biomass is renewable and consumes atmospheric CO2 during growth, it can have a small net CO2 impact compared to fossil fuels. However, hydrogen from biomass has major challenges. There are no completed technology demonstrations. The yield of hydrogen is low from biomass since the hydrogen content in biomass is low to being with (approximately 6% versus 25% for methane) and the energy content is low due to the 40% oxygen content of biomass. Since over half of the hydrogen from biomass comes from splitting water in the steam reforming reaction, the energy content of the feedstock is an inherent limitation of the process . The low yield of hydrogen on a weight basis is misleading since the energy conversion efficiency is high. However, the cost for growing, harvesting, and transporting biomass is high. Thus even with reasonable energy efficiencies, it is not presently economically competitive with natural gas steam reforming for stand-alone hydrogen without the advantage of high-value co-products. Additionally, as with all sources of hydrogen, production from biomass will require appropriate hydrogen storage and utilization systems to be developed and deployed. The report also looked at promising areas for further research and development. The major areas for R,D and D are: feedstock preparation and feeding; gasification gas conditioning; system integration; modular systems development; valuable co-product integration; and larger-scale demonstrations. These are in addition to the challenges for any hydrogen process in storage and utilization technologies.

Aquifer stability investigations  

DOE Green Energy (OSTI)

The study of compressed air energy storage (CAES) in porous rock reservoirs is carried out within the Reservoir Stability Studies Program at Pacific Northwest Laboratory. The goal of the study is to establish criteria for long-term stability of aquifer CAES reservoirs. These criteria are intended to be guidelines and check lists that utilities and architect-engineering firms may use to evaluate reservoir stability at candidate CAES sites. These criteria will be quantitative where possible, qualitative where necessary, and will provide a focal point for CAES relevant geotechnical knowledge, whether developed within this study or available from petroleum, mining or other geotechnical practices using rock materials. The Reservoir Stability Studies Program had four major activities: a state-of-the-art survey to establish preliminary stability criteria and identify areas requiring research and development; numerical modeling; laboratory testing to provide data for use in numerical models and to investigate fundamental rock mechanics, thermal, fluid, and geochemical response of aquifer materials; and field studies to verify the feasibility of air injection and recovery under CAES conditions in an aquifer, to validate and refine the stability criteria, and to evaluate the accuracy and adequacy of the numerical and experimental methodologies developed in previous work. Three phases of study, including preliminary criteria formulation, numerical model development, and experimental assessment of CAES reservoir materials have been completed. Present activity consists of construction and operation of the aquifer field test, and associated numerical and experimental work in support of that activity. Work is presently planned to be complete by 1983 at the end of the field test. At that time the final stability criteria for aquifers will be issued. Attached here also are preliminary criteria for aquifers.

A General Simulation Framework for Supply Chain Modeling: State of the Art and Case Study  

E-Print Network (OSTI)

Nowadays there is a large availability of discrete event simulation software that can be easily used in different domains: from industry to supply chain, from healthcare to business management, from training to complex systems design. Simulation engines of commercial discrete event simulation software use specific rules and logics for simulation time and events management. Difficulties and limitations come up when commercial discrete event simulation software are used for modeling complex real world-systems (i.e. supply chains, industrial plants). The objective of this paper is twofold: first a state of the art on commercial discrete event simulation software and an overview on discrete event simulation models development by using general purpose programming languages are presented; then a Supply Chain Order Performance Simulator (SCOPS, developed in C++) for investigating the inventory management problem along the supply chain under different supply chain scenarios is proposed to readers.

Characterization Report for the David Witherspoon Screen Art Site  

SciTech Connect

The U.S. Department of Energy (DOE) Oak Ridge Office (ORO) of Environmental Management (EM) requested the technical assistance of Oak Ridge Institute for Science and Education (ORISE) to characterize a tract of land associated with the David Witherspoon, Incorporated (DWI) Volunteer Equipment and Supply Company (VESC). This tract of land (hereinafter referred to as Screen Arts) is located in the Vestal Community in the 2000-block of Maryville Pike in south Knoxville, Tennessee, as shown in Figure A-1. This tract of land has been used primarily to store salvaged equipment and materials for resale, recycle, or for disposal in the former landfill once operated by DWI. The DWI Site industrial landfill and metal recycling business had been permitted by the Tennessee Division of Radiological Health to accept low-level radiologically contaminated metals. DWI received materials and equipment associated with operations from DOE sites, including those in Oak Ridge, Tennessee; Paducah, Kentucky; and Portsmouth, Ohio. It is likely that items stored at Screen Arts may have contained some residual radiological materials.

Color, the Visual Arts, and Representations of Otherness in the Victorian Novel  

E-Print Network (OSTI)

This dissertation investigates the cultural connections made between race and color in works of fiction from the Victorian and Edwardian era, particularly how authors who are also artists invent fantastically colored characters who are purple, blue, red, and yellow to rewrite (and sometimes reclaim) difference in their fiction. These strange and eccentric characters include the purple madwoman in Charlotte Brontë’s Jane Eyre (1847), the blue gentleman from Wilkie Collins’s Poor Miss Finch (1872), the red peddler in Thomas Hardy’s The Return of the Native (1878), and the little yellow girls of Arthur Conan Doyle’s “The Yellow Face” (1893) and Frances Hodgson Burnett’s The Secret Garden (1911). These fictional texts serve as a point of access into the cultural meanings of color in the nineteenth century and are situated at the intersection of Victorian discourses on the visual arts and race science. The second half of the nineteenth century constitutes a significant moment in the history of color: the rapid development of new color technologies helps to trigger the upheavals of the first avant-garde artistic movements and a reassessment of coloring’s prestige in the art academies. At the same time, race science appropriates color, using it as a criterion for classification in the establishment of global racial hierarchies. By imagining what it would be like to change one’s skin color, these artist-authors employ the aesthetic realm of color to explore the nature of human difference and alterity. In doing so, some of them are able to successfully formulate their own challenges to nineteenth-century racial discourse.

E-Print Network (OSTI)

Solar astrometry deals with the accurate measumerent of the solar diameter, and in general with the measurement of the shape of the Sun. During the last decades several techniques have been developed to monitor the radius and the irradiance of the Sun: meridian transits, telescopes in drift-scan mode, solar astrolabes, balloons, and satellites dedicated to the measurements of the solar diameter, and space measurements of the total solar irradiance are now performed to know the relationship radius-luminosity for the Sun in this evolutionary stage of its life. The feedback of solar astrometry in climate studies is of paramount importance. The status of art in the various fields of research here adressed is outlined.

Looking for Science in the Art of Network Measurement  

E-Print Network (OSTI)

. Network measurements are crucial both to drive research and in network operations. We introduce a taxonomy and survey the state of the art of network measurement. We compare measurements available at the network layer with those available at higher layers, specifically the DNS and the Web. Both the DNS and the Web can be viewed as logical networks; this allows the direct comparison of measurement methods available at these layers with those available at the network layer. We argue that measurement support within the DNS and the Web is insufficient in light of the fact that they affect end-user performance as much as the network layer. We derive some recommendations for the reuse of network layer measurement methods in the DNS and the Web. 1

State of the art of pressurized fluidized bed combustion systems  

SciTech Connect

This report was prepared at the request of the Tennessee Valley Authority (TVA) to clarify the development status of the pressurized fluidized bed combustor (PFBC) and to place in perspective the problems which are yet to be solved before commercialization of the concept is practical. This report, in essence, supersedes the interim report published in 1979, Assessment of the State of the Art of Pressurized Fluidized Bed Combustion Systems. A brief overview of the PFBC concept is included citing potential advantages and disadvantages relative to atmospheric fluidized bed combustion (AFBC) and conventional pulverized coal plants. A survey of existing and developing PFBC experimental facilities is presented in some detail which includes the major accomplishments at the respective facilities. Recent data on plant emissions, turbine/gas cleanup systems, and overall efficiency are provided. Findings of several design studies are also discussed. The results of recent gas turbine and cascade tests have been encouraging although the full assessment of the accomplishments have not been made. The delay in construction of the Grimethorpe plant causes further delay in proof-testing full-size, rotating turbomachinery. Several parameters are recommended for further assessment in design studies including: (1) effect of turbine life on cost of power; and (2) effect of reduced gas turbine inlet temperature and pressure on cost of power.

The research funded by this NEER grant establishes the framework for a detailed understanding of the challenges in beta dosimetry, especially in the presence of a mixed radiation field. The work also stimulated the thinking of the research group which will lead to new concepts in digital signal processing to allow collection of detection signals and real-time analysis such that simultaneous beta and gamma spectroscopy can take place. The work described herein (with detail in the many publications that came out of this research) was conducted in a manner that provided dissertation and thesis topics for three students, one of whom was completely funded by this grant. The overall benefit of the work came in the form of a dramatic shift in signal processing that is normally conducted in analog pulse shape analysis. Analog signal processing was shown not to be feasible for this type of work; digital signal processing was a must. This, in turn, led the research team to a new understanding of pulse analysis, one in which expands the state-of-the-art in simultaneous beta and gamma spectroscopy with a single detector.

State-of-the-art report on piping fracture mechanics  

Science Conference Proceedings (OSTI)

This report is an in-depth summary of the state-of-the-art in nuclear piping fracture mechanics. It represents the culmination of 20 years of work done primarily in the US, but also attempts to include important aspects from other international efforts. Although the focus of this work was for the nuclear industry, the technology is also applicable in many cases to fossil plants, petrochemical/refinery plants, and the oil and gas industry. In compiling this detailed summary report, all of the equations and details of the analysis procedure or experimental results are not necessarily included. Rather, the report describes the important aspects and limitations, tells the reader where he can go for further information, and more importantly, describes the accuracy of the models. Nevertheless, the report still contains over 150 equations and over 400 references. The main sections of this report describe: (1) the evolution of piping fracture mechanics history relative to the developments of the nuclear industry, (2) technical developments in stress analyses, material property aspects, and fracture mechanics analyses, (3) unresolved issues and technically evolving areas, and (4) a summary of conclusions of major developments to date.

Wind power forecasting : state-of-the-art 2009.  

DOE Green Energy (OSTI)

Many countries and regions are introducing policies aimed at reducing the environmental footprint from the energy sector and increasing the use of renewable energy. In the United States, a number of initiatives have been taken at the state level, from renewable portfolio standards (RPSs) and renewable energy certificates (RECs), to regional greenhouse gas emission control schemes. Within the U.S. Federal government, new energy and environmental policies and goals are also being crafted, and these are likely to increase the use of renewable energy substantially. The European Union is pursuing implementation of its ambitious 20/20/20 targets, which aim (by 2020) to reduce greenhouse gas emissions by 20% (as compared to 1990), increase the amount of renewable energy to 20% of the energy supply, and reduce the overall energy consumption by 20% through energy efficiency. With the current focus on energy and the environment, efficient integration of renewable energy into the electric power system is becoming increasingly important. In a recent report, the U.S. Department of Energy (DOE) describes a model-based scenario, in which wind energy provides 20% of the U.S. electricity demand in 2030. The report discusses a set of technical and economic challenges that have to be overcome for this scenario to unfold. In Europe, several countries already have a high penetration of wind power (i.e., in the range of 7 to 20% of electricity consumption in countries such as Germany, Spain, Portugal, and Denmark). The rapid growth in installed wind power capacity is expected to continue in the United States as well as in Europe. A large-scale introduction of wind power causes a number of challenges for electricity market and power system operators who will have to deal with the variability and uncertainty in wind power generation when making their scheduling and dispatch decisions. Wind power forecasting (WPF) is frequently identified as an important tool to address the variability and uncertainty in wind power and to more efficiently operate power systems with large wind power penetrations. Moreover, in a market environment, the wind power contribution to the generation portofolio becomes important in determining the daily and hourly prices, as variations in the estimated wind power will influence the clearing prices for both energy and operating reserves. With the increasing penetration of wind power, WPF is quickly becoming an important topic for the electric power industry. System operators (SOs), generating companies (GENCOs), and regulators all support efforts to develop better, more reliable and accurate forecasting models. Wind farm owners and operators also benefit from better wind power prediction to support competitive participation in electricity markets against more stable and dispatchable energy sources. In general, WPF can be used for a number of purposes, such as: generation and transmission maintenance planning, determination of operating reserve requirements, unit commitment, economic dispatch, energy storage optimization (e.g., pumped hydro storage), and energy trading. The objective of this report is to review and analyze state-of-the-art WPF models and their application to power systems operations. We first give a detailed description of the methodologies underlying state-of-the-art WPF models. We then look at how WPF can be integrated into power system operations, with specific focus on the unit commitment problem.

Youth, Art, and Life on the Border: An Examination of Coping and Support among Participants in a Migrant Art Program  

E-Print Network (OSTI)

This case study examined coping strategies and support systems utilized by 33 children of Hispanic migrant farmworkers from Fabens, Texas. The youth participated in the summer 2011 Creative Kids Incorporated Migrant Program in El Paso, Texas. The study examined how socio-ecological factors, specifically within Creative Kids Inc., help youth to cope with risk factors and aid in the resilience process. This study applied both qualitative and quantitative approaches. The qualitative portion consisted of 12 in-depth program participant interviews, ages 9-15, and observations at Creative Kids Inc. The quantitative portion consisted of a survey that utilized the Brief Adolescent Life Event Scale, the Children Coping Strategies Checklist, and the Multi-Dimensional Support Scale. Thirty-four surveys were distributed, and 33 surveys were analyzed from program participants ages 10-15. The study found the youth were affected by various risk factors within their environment, such as poverty, separation from family, and school. When adapting to stress, most youth utilized behavioral-based distraction strategies (i.e., listening to music and playing outside) and cognitive-based avoidance strategies (i.e., not thinking about their problem) to cope. The youth did not use active coping strategies as often as avoidance strategies. However, some support seeking strategies were mentioned. Most often, youth sought support from parents and older siblings. While the youth sought support from their teachers, it was mainly in regard to school work. Similarly, youth sought support from Creative Kids Inc. staff concerning their art projects. Families were beneficial to youth in the coping process, because they provided youth with opportunities for distracting activities as well as some support. Although the youth strongly enjoyed participating in the Migrant Program, they rarely sought support for personal stressors or problems from the staff. Yet, the program provided youth with opportunities to participate in distracting activities, express their feelings, and seek out support. Despite the lack of literature on children of Hispanic migrant farmworkers and the factors that influence their resilience, this study provided an in-depth description of how they cope with daily life events, what support systems are available to assist in overcoming risks, and provided a basis for understanding the role of support systems in facilitating resiliency among this adolescent group.

Composite tube cracking in kraft recovery boilers: A state-of-the-art review  

Science Conference Proceedings (OSTI)

Beginning in the mid-1960s, increasing energy costs in Finland and Sweden made energy recovery more critical to the cost-effective operation of a kraft pulp mill. Boiler designers responded to this need by raising the steam operating pressure, but almost immediately the wall tubes in these new boilers began to corrode rapidly. Test panels installed in the walls of the most severely corroding boiler identified austenitic stainless steel as sufficiently resistant to the new corrosive conditions, and discussions with Sandvik AB, a Swedish tube manufacturer, led to the suggestion that coextruded tubes be used for water wall service in kraft recovery boilers. Replacement of carbon steel by coextruded tubes has solved most of the corrosion problems experienced by carbon steel wall tubes, however, these tubes have not been problem-free. Beginning in early 1995, a multidisciplinary research program funded by the US Department of Energy was established to investigate the cause of cracking in coextruded tubes and to develop improved materials for use in water walls and floors of kraft recovery boilers. One portion of that program, a state-of-the-art review of public- and private-domain documents related to coextruded tube cracking in kraft recovery boilers is reported here. Sources of information that were consulted for this review include the following: tube manufacturers, boiler manufacturers, public-domain literature, companies operating kraft recovery boilers, consultants and failure analysis laboratories, and failure analyses conducted specifically for this project. Much of the information contained in this report involves cracking problems experienced in recovery boiler floors and those aspects of spout and air-port-opening cracking not readily attributable to thermal fatigue. 61 refs.

A course in flow visualization: The art and physics of fluid flow  

E-Print Network (OSTI)

In Spring 2003, a new experimental course on flow visualization was offered to a mixed class of Fine Arts Photography and Engineering students. Course content included fluid flow physics, history of photography with respect to the relationship of science and art, as well as flow visualization and photography techniques. Issues such as “What makes an image art? What makes an image scientific? ” were addressed. The class focused on studio/laboratory experiences for mixed teams of students. A range of fluids apparatus were made available, and students also created novel flows. Writeups were required for each image (to the art students ’ shock). Student work was evaluated for both artistic and scientific merit. This course represents a radical departure from normal engineering curricula; typically all fine arts studio courses are specifically excluded. However, the course proved to be very successful in attracting both graduate and undergraduate students, engineering women in particular. One outcome of the course is the recognition by students of the beauty of fluid physics that surrounds us each day, leading to motivation for life-long learning.

State-of-the-Art Highly Insulating Window Frames - Research and Market State-of-the-Art Highly Insulating Window Frames - Research and Market Review Title State-of-the-Art Highly Insulating Window Frames - Research and Market Review Publication Type Report LBNL Report Number LBNL-1133E Year of Publication 2007 Authors Gustavsen, Arlid, Bjørn Petter Jelle, Dariush K. Arasteh, and Christian Kohler Call Number LBNL-1133E Abstract This document reports the findings of a market and research review related to state-of-the-art highly insulating window frames. The market review focuses on window frames that satisfy the Passivhaus requirements (window U-value less or equal to 0.8 W/m2K), while other examples are also given in order to show the variety of materials and solutions that may be used for constructing window frames with a low thermal transmittance (U-value). The market search shows that several combinations of materials are used in order to obtain window frames with a low U-value. The most common insulating material seems to be Polyurethane (PUR), which is used together with most of the common structural materials such as wood, aluminum, and PVC.

Demonstration of LED Retrofit Lamps at the Jordan Schnitzer Museum of Art  

SciTech Connect

The Jordan Schnitzer Museum of Art in Eugene, Oregon, houses a remarkable permanent collection of Asian art and antiquities, modern art, and sculpture, and also hosts traveling exhibitions. In the winter and spring of 2011, a series of digital photographs by artist Chris Jordan, titled "Running the Numbers," was exhibited in the Coeta and Donald Barker Special Exhibitions Gallery. These works graphically illustrate waste (energy, money, health, consumer objects, etc.) in contemporary culture. The Bonneville Power Administration and the Eugene Water and Electricity Board provided a set of Cree 12W light-emitting diode (LED) PAR38 replacement lamps (Cree LRP38) for the museum to test for accent lighting in lieu of their standard Sylvania 90W PAR38 130V Narrow Flood lamps (which draw 78.9W at 120V). At the same time, the museum tested LED replacement lamps from three other manufacturers, and chose the Cree lamp as the most versatile and most appropriate color product for this exhibit. The lamps were installed for the opening of the show in January 2011. This report describes the process for the demonstration, the energy and economic results, and results of a survey of the museum staff and gallery visitors on four similar clusters of art lighted separately by four PAR38 lamps.

The LIFE Laser Design in Context: A Comparison to the State-of-the-Art  

Science Conference Proceedings (OSTI)

The current point design for the LIFE laser leverages decades of solid-state laser development in order to achieve the performance and attributes required for inertial fusion energy. This document provides a brief comparison of the LIFE laser point design to other state-of-the-art solid-state lasers. Table I compares the attributes of the current LIFE laser point design to other systems. the state-of-the-art for single-shot performance at fusion-relevant beamline energies is exemplified by performance observed on the National Ignition Facility. The state-of-the-art for high average power is exemplified by the Northrup Grumman JHPSSL laser. Several items in Table I deal with the laser efficiency; a more detailed discussion of efficiency can be found in reference 5. The electrical-to-optical efficiency of the LIFE design exceeds that of reference 4 due to the availability of higher efficiency laser diode pumps (70% vs. {approx}50% used in reference 4). LIFE diode pumps are discussed in greater detail in reference 6. The 'beam steering' state of the art is represented by the deflection device that will be used in the LIFE laser, not a laser system. Inspection of Table I shows that most LIFE laser attributes have already been experimentally demonstrated. The two cases where the LIFE design is somewhat better than prior experimental work do not involve the development of new concepts: beamline power is increased simply by increasing aperture (as demonstrated by the power/aperture comparison in Table I), and efficiency increases are achieved by employing state-of-the-art diode pumps. In conclusion, the attributes anticipated for the LIFE laser are consistent with the demonstrated performance of existing solid-state lasers.

Lithium: Thionyl chloride battery state-of-the-art assessment  

DOE Green Energy (OSTI)

Models of the performance of primary Li/SOCl{sub 2} cells can provide for realistic comparisons between technical information from different sources, and set standards that electronic circuit designers may refer to in the generation of high-quality products. Data from various investigators were used to derive mathematical- statistical relationships with physical design features (e.g. size and materials), operating parameters (e.g. current and temperature) and storage conditions (time and temperature). These efforts were substantially promoted by normalization procedures. For example, current loads were converted into current densities, or if appropriate, into current per unit cathode volume. Similarly, cell capacities were standardized with the maximum values observed at low current and also with respect to the cathode volume. Particular emphasis was placed on evaluations of voltage-delay, cell capacity and self-discharge, for which several equations were established. In spite of a considerable expenditure in time to find high-quality datasets, the reality is that all of the reviewed studies are flawed in one way or another. Specifically, all datasets are afflicted with sizable experimental errors and the precision of the regression equations is much lower than is deemed necessary for a universal model of the lithium thionyl chloride cell. Each of the equations has some definite truth content, but is generally incapable of bridging the gap between different studies. The basic failure to come up with a unifying model for Li/SOCl{sub 2} batteries leaves only one benefit of the present analysis, namely to provide guidance for future investigations. Several recommendations are made based on the insight gained during the search for good data in the relevant literature.

Standardizing the Art of Electron-Beam Welding. Standardizing the Art of Electron-Beam Welding. WELDED materials are an integral part of everyday life. Appliances, cars, and bridges are all made by welding materials together. But not all welds are created equal. Welding methods vary in complexity, time, and cost, depending on a product's requirements and purpose. In electron-beam (EBeam) welding, an electron beam generated in a vacuum creates a fusing heat source that can unite almost any metals. This method produces deep welds without adding excessive heat that can adversely affect the properties of the surrounding metal. In the nuclear energy and aerospace industries, electron-beam welding is preferred for manufacturing high-value welds-those in which defects cannot be tolerated.

Arasteh, Howdy Goudey, and Robert Hart Journal Solar Energy Materials and Solar Cells Volume 96 Start Page 1 Pagination 1-28 Date Published 01/2012 Keywords Fenestration, Low-e, Multilayer glazing, Smart window, Solar cell glazing, Vacuum glazing Abstract Fenestration of today is continuously being developed into the fenestration of tomorrow, hence offering a steadily increase of daylight and solar energy utilization and control, and at the same time providing a necessary climate screen with a satisfactory thermal comfort. Within this work a state of the art market review of the best performing fenestration products has been carried out, along with an overview of possible future research opportunities for the fenestration industry. The focus of the market review was low thermal transmittance (U-value). The lowest centre of glass Ug-values found was 0.28 W/(m2K) and 0.30 W/(m2K), which was from a suspended coating glazing product and an aerogel glazing product, respectively. However, the majority of high performance products found were triple glazed. The lowest frame U-value was 0.61 W/(m2K). Vacuum glazing, smart windows, solar cell glazing, window frames, self cleaning glazing, low-emissivity coatings and spacers were also reviewed, thus also representing possibilities for controlling and harvesting the solar radiation energy. Currently, vacuum glazing, new spacer materials and solutions, electrochromic windows and aerogel glazing seem to have the largest potential for improving the thermal performance and daylight and solar properties in fenestration products. Aerogel glazing has the lowest potential U-values, ~ 0.1 W/(m2K), but requires further work to improve the visible transmittance. Electrochromic vaccum glazing and evacuated aerogel glazing are two vacuum related solutions which have a large potential. There may also be opportunities for completely new material innovations which could revolutionize the fenestration industry.

An integrated process with 100,000 bpsd (4.93 Mt/a) syncrude capacity is proposed as the basic building block of an oil shale industry in western Colorado. Key components are longwall mining/backfilling and hydroretorting of the shale. They integrated with: pulverizing, pressurizing, and preheating of the raw shale; cooling, depressurizing, conditioning, and compaction of the spent shale; topping and bottoming of the syncrude for feed to hydrogen and utilities production, respectively; and pipeline transport of the stable heart cut to remote refining areas(s). These components use proven state-of-the-art unit operations technologies. Sizes, characteristics, and interactions of the major components are discussed.

Wind-turbine siting: a summary of the state of the art  

DOE Green Energy (OSTI)

The process of siting large wind turbines may be divided into two broad steps: site selection, and site evaluation. Site selection is the process of locating windy sites where wind energy development shows promise of economic viability. Site evaluation is the process of determining in detail for a given site the economic potential of the site. This paper emphasizes the state of the art in the first aspect of siting, site selection. Several techniques for assessing the wind resource have been explored or developed in the Federal Wind Energy Program. Local topography and meteorology will determine which of the tehniques should be used in locating potential sites.

A State-of-the-Art Assessment of Zero Net Energy Homes  

Science Conference Proceedings (OSTI)

This Technical Update is a review of the state of the art of zero net energy homes (ZNEHs). A zero net energy home is one that produces as much energy as it uses on an annual basis, typically using a rooftop photovoltaic (PV) system on a very low energy building. The key to creating a ZNEH is to minimize the size of costly PV systems by maximizing the energy efficiency of the home and its end-use equipment. The focus here is on single-family houses, the residential segment for which most ZNEH research an...

Our Interdisciplinary Science investigation addresses the primary biogeochemical cycles of planet Earth and considers, in particular, how they are being changed by humans. The efforts focus on the cycles of water, carbon, nitrogen, and selected trace gases. Process-based models are developed as modules, in concert with database management techniques which synthesize the in-situ and remote sensing data needed to characterize regional and global scales. Models of the Earth's biogeochemical cycles are a central theme. They provide a rigorous means for developing quantitative projections of the interactions of atmospheric composition, climate, terrestrial and aquatic ecosystems, ocean circulation and sea level, and the effects of human activities. The family of models being developed in this investigation provide the predictive link between the physical and biological Earth system and the human dimensions of global change. The long-term goal of our IDS research is to understand the primary biogeochemical cycles of the planet, the nature of the coupling between the Biogeochemical Subsystem and the Physical-Climate Subsystem, and the characteristics of the human forcing of the Biogeochemical Subsystem and hydrological cycle. Our strategy is to study how element cycles function in natural systems where perturbations in biogeochemical states are driven primarily by climate variability

Experimental investigation of creep behavior of reactor vessel lower head  

SciTech Connect

The objective of the USNRC supported Lower Head Failure (LHF) Experiment Program at Sandia National Laboratories is to experimentally investigate and characterize the failure of the reactor pressure vessel (RPV) lower head due to the thermal and pressure loads of a severe accident. The experimental program is complemented by a modeling program focused on the development of a constitutive formulation for use in standard finite element structure mechanics codes. The problem is of importance because: lower head failure defines the initial conditions of all ex-vessel events; the inability of state-of-the-art models to simulate the result of the TMI-II accident (Stickler, et al. 1993); and TMI-II results suggest the possibility of in-vessel cooling, and creep deformation may be a precursor to water ingression leading to in-vessel cooling.

ART CCIM Phase II-A Off-Gas System Evaluation Test Plan  

Science Conference Proceedings (OSTI)

This test plan defines testing to be performed using the Idaho National Laboratory (INL) engineering-scale cold crucible induction melter (CCIM) test system for Phase II-A of the Advanced Remediation Technologies (ART) CCIM Project. The multi-phase ART-CCIM Project is developing a conceptual design for replacing the joule-heated melter (JHM) used to treat high level waste (HLW) in the Defense Waste Processing Facility (DWPF) at the Savannah River Site (SRS) with a cold crucible induction melter. The INL CCIM test system includes all feed, melter off-gas control, and process control subsystems needed for fully integrated operation and testing. Testing will include operation of the melter system while feeding a non-radioactive slurry mixture prepared to simulate the same type of waste feed presently being processed in the DWPF. Process monitoring and sample collection and analysis will be used to characterize the off-gas composition and properties, and to show the fate of feed constituents, to provide data that shows how the CCIM retrofit conceptual design can operate with the existing DWPF off-gas control system.

A study on the human ability to detect soot deposition onto works of art  

SciTech Connect

Works of art can become soiled due to the deposition of airborne black soot particles within museums and art galleries. The soot particle deposition rates are already known for many environments, but knowing the levels of carbon particle coverage at which humans can detect image darkening is also important. Therefore, in this work, human subjects have been tested to determine their ability to detect soiling by black carbon particles deposited onto specially prepared samples having colored backgrounds. The results show that certain observers are able to detect that a sample is becoming soiled once surface coverage by black carbon particles has reached 2.4% if the soiled samples and clean samples are placed directly adjacent to each other, producing a sharp dividing line (an ``edge-to-edge'' comparison). Observers can detect the presence of soiling with greater than 90% accuracy during an edge-to-edge comparison on most backgrounds when soiling levels reach approximately 3.6% surface coverage by black particles. If the comparison between soiled and clean samples must be made with samples that are separated from each other by a neutral gray area, soiling is only detected with 100% accuracy once coverage by black particles has reached 12.0% surface coverage. These results show that a greater accumulation of black carbon than was previously thought is required to produce a visibly soiled surface.

T Plant Cell Investigation  

Science Conference Proceedings (OSTI)

The Waste Management Project within Fluor Hanford performed an initial investigation of the current and historical contents of 221-T (T Plant Canyon) process cells. This Phase I report is intended to be followed by a final, more detailed, Phase II report. This information has been gathered in order to help reduce uncertainties and future surprises regarding cell contents during future work in and around T Plant process cells. The information was obtained from available documentation and was compiled into a database that is included in the report. Resolution of any apparently conflicting information was not a part of the Phase I effort. No information has been found to date that would indicate there could be a significant unexpected hazard in any of the process cells.

Ultrasonic mitigation investigation  

DOE Green Energy (OSTI)

The suggestion was made that the introduction of ultrasound into Tank 101-SY might serve to release the hydrogen bubbles trapped in the slurry. This would cause a continuous release of bubbles and thereby prevent the turnover phenomenon. Two major considerations were (1) the method for delivering the energy into the slurry and (2) the effective volume of action. In this study, we attached the former by designing and testing a liquid-filled waveguide and radiator, and the latter by making ultrasonic property measurements on synthetic waste. Our conclusion is that ultrasonic mitigation may not be feasible, primarily because of the very high attenuation (1000 to 50000 dB/m) factor to 10 to 30 kHz. Such a high attenuation would restrict the action volume to such a low value as to make the method impractical. Further investigations are recommended to identify the cause of this effect and determine if this same effect will be seen in real 101-SY waste.

Performance Characteristics of an Electrochemically Powered Turboprop: A Comparison with State of the Art Gas Turbines  

E-Print Network (OSTI)

As we search for alternative fuels and energy efficient vehicles it is important to consider the role of electrochemical fuel cells in aircraft propulsion systems. This paper focuses on this issue with regards to small turboprop aircraft. An electrochemical propulsion system would employ liquid hydrogen in an air breathing fuel cell that would generate electricity to run electric motors which in tum power the props. The major question this paper addresses is: under what conditions will a hydrogen/fuel cell power system be superior to a state of the art hydrogen/gas turbine power system? The systems are compared on a fuel consumption basis, a cost basis, and a reliability/ maintainability basis. The analysis show that both specific power and efficiency play an important role in determining which configuration uses less fuel. In general, the fuel cell system is heavier but more efficient than the gas turbine. It appears that the fuel cell system will begin to compete with the gas turbine as the power densities surpass 1 kw/kg and the efficiencies approaches .45. From a cost perspective gas turbines presently cost $500/ Kw and fuel cells are far more expensive. However, the raw materials in a fuel cell are inexpensive and could conceivably be cheaper, thus making the fuel cells increasingly attractive. From a reliability perspective, the fuel cell system appears to have a significant advantage due to the lack of moving parts and the high reliability of electric motors.

Intermediate Photovoltaic System Application Experiment. Oklahoma Center for Science and Arts. Phase II. Final report  

DOE Green Energy (OSTI)

This report presents the key results of the Phase II efforts for the Intermediate PV System Applications Experiment at the Oklahoma Center for Science and Arts (OCSA). This phase of the project involved fabrication, installation and integration of a nominal 140 kW flat panel PV system made up of large, square polycrystalline-silicon solar cell modules, each nominally 61 cm x 122 cm in size. The output of the PV modules, supplied by Solarex Corporation, was augmented, 1.35 to 1 at peak, by a row of glass reflectors, appropriately tilted northward. The PV system interfaces with the Oklahoma Gas and Electric Utility at the OCSA main switchgear. Any excess power generated by the system is fed into the utility under a one to one buyback arrangement. Except for a shortfall in the system output, presently suspected to be due to the poor performance of the modules, no serious problems were encountered. Certain value engineering changes implemented during construction and early operational failure events associated with the power conditioning system are also described. The system is currently undergoing extended testing and evaluation.

State-of-the-art hydrogen sulfide control for geothermal energy systems: 1979  

DOE Green Energy (OSTI)

Existing state-of-the-art technologies for removal of hydrogen sulfide are discussed along with a comparative assessment of their efficiencies, reliabilities and costs. Other related topics include the characteristics of vapor-dominated and liquid-dominated resources, energy conversion systems, and the sources of hydrogen sulfide emissions. It is indicated that upstream control technologies are preferred over downsteam technologies primarily because upstream removal of hydrogen sulfide inherently controls all downstream emissions including steam-stacking. Two upstream processes for vapor-dominated resources appear promising; the copper sulfate (EIC) process, and the steam converter (Coury) process combined with an off-gas abatement system such as a Stretford unit. For liquid-dominated systems that produce steam, the process where the non-condensible gases are scrubbed with spent geothermal fluid appears to be promising. An efficient downstream technology is the Stretford process for non-condensible gas removal. In this case, partitioning in the surface condenser will determine the overall abatement efficiency. Recommendations for future environmental control technology programs are included.

Solar energy in Kentucky's homes: the state of the art. [Monograph  

SciTech Connect

Information on the state of the art of residential solar energy use in Kentucky covers basic solar energy terms and concepts and a discussion of the suitability of Kentucky's climate for solar energy use. Climatic comparisons of Kentucky and the rest of the nation show that the amount of sunshine in Kentucky is more than adequate for use in home heating. The second section discusses the financial and legal considerations of whether residential solar energy is economically justified, given the high initial costs. A simulated comparison with gas and electric heating shows solar energy to be economically attractive only when electricity is the alternative fuel. Passive systems, which were not evaluated, however, are very economical. Tax incentives are available at the federal level. The state legislature is considering tax incentives, but has not addressed solar access. A mail survey of homeowners indicates satisfaction among 82% of the 51 solar home owners. Repairs are the major cause of dissatisfaction. The report concludes that now is the time for homeowners to explore alternatives to conventional fuels and, particularly, to consider solar energy. 64 references, 7 figures, 23 tables.

Reclaiming the Ungentlemanly Arts: The Global Origins of SOE and OSS  

E-Print Network (OSTI)

Sir Colin McV. Gubbins, former director of Britain's Special Operations Executive (SOE), explained in 1966 to a Danish audience that it is much easier to pronounce a new organization than to actually create it. This dissertation examines the processes whereby SOE was created, including how its doctrine was formulated and subsequently disseminated, both to its own agents and to its American counterpart, the Office of Strategic Services (OSS). Traditional narratives, which imply that SOE had no precedents, fail to appreciate that Gubbins and his colleagues consciously looked to past and contemporary examples for inspiration. This dissertation follows Gubbins's career, examining his experience of unconventional warfare in the Allied Intervention in Russia, in Ireland during the Irish Revolution, and in India. To personal experience was added the experience of colleagues and the knowledge he gained by study of several other historical and contemporary conflicts. Pragmatically synthesizing this information, Gubbins authored two brief guides in 1939: the Art of Guerilla Warfare and the Partisan Leader's Handbook. In 1940 Gubbins joined the new SOE and was given charge of both operations and training, allowing his ideas to shape SOE's agents and form their thinking. Even before the entry of the United States into the Second World War, OSS turned to Britain for training in intelligence and sabotage. SOE played a substantial role in this process, propagating Gubbins's ideas even further. Although the Americans drew upon their own sources of inspiration as well, SOE and Gubbins's doctrines were significant, arguably central, to American thinking.

ART CCIM PHASE II-A OFF-GAS SYSTEM EVALUATION TEST REPORT  

SciTech Connect

AREVA Federal Services (AFS) is performing a multi-year, multi-phase Advanced Remediation Technologies (ART) project, sponsored by the U.S. Department of Energy (DOE), to evaluate the feasibility and benefits of replacing the existing joule-heated melter (JHM) used to treat high level waste (HLW) in the Defense Waste Processing Facility (DWPF) at the Savannah River Site with a cold crucible induction melter (CCIM). The AFS ART CCIM project includes several collaborators from AREVA subsidiaries, French companies, and DOE national laboratories. The Savannah River National Laboratory and the Commissariat a l’Energie Atomique (CEA) have performed laboratory-scale studies and testing to determine a suitable, high-waste-loading glass matrix. The Idaho National Laboratory (INL) and CEA are performing CCIM demonstrations at two different pilot scales to assess CCIM design and operation for treating SRS sludge wastes that are currently being treated in the DWPF. SGN is performing engineering studies to validate the feasibility of retrofitting CCIM technology into the DWPF Melter Cell. The long-term project plan includes more lab-testing, pilot- and large-scale demonstrations, and engineering activities to be performed during subsequent project phases. A simulant of the DWPF SB4 feed was successfully fed and melted in a small pilot-scale CCIM system during two test series. The OGSE tests provide initial results that (a) provide melter operating conditions while feeding a DWPF SB4 simulant feed, (b) determine the fate of feed organic and metal feed constituents and metals partitioning, and (c) characterize the melter off-gas source term to a downstream off-gas system. The INL CCIM test system was operated continuously for about 30 hours during the parametric test series, and for about 58 hours during the OGSE test. As the DWPF simulant feed was continuously fed to the melter, the glass level gradually increased until a portion of the molten glass was drained from the melter. The glass drain was operated periodically on-demand. A cold cap of unmelted feed was controlled by adjusting the feedrate and melter power levels to obtain the target molten glass temperatures with varying cold cap levels. Three test conditions were performed per the test plan, during which the melter was operated with a target melt temperature of either 1,250oC or 1,300oC, and with either a partial or complete cold cap of unmelted feed on top of the molten glass. Samples of all input and output streams including the starting glass, the simulant feed, the off-gas particulate matter, product glass, and deposits removed from the crucible and off-gas pipe after the test were collected for analysis.

STATE OF THE ART AND FUTURE DEVELOPMENTS IN NATURAL GAS ENGINE TECHNOLOGIES  

DOE Green Energy (OSTI)

Current, state of the art natural gas engines provide the lowest emission commercial technology for use in medium heavy duty vehicles. NOx emission levels are 25 to 50% lower than state of the art diesel engines and PM levels are 90% lower than non-filter equipped diesels. Yet, in common with diesel engines, natural gas engines are challenged to become even cleaner and more efficient to meet environmental and end-user demands. Cummins Westport is developing two streams of technologies to achieve these goals for medium-heavy and heavy-heavy duty applications. For medium-heavy duty applications, lowest possible emissions are sought on SI engines without significant increase in complexity and with improvements in efficiency and BMEP. The selected path builds on the capabilities of the CWI Plus technology and recent diesel engine advances in NOx controls, providing potential to reduce emissions to 2010 values in an accelerated manner and without the use of Selective Catalytic Reduction or NOx Storage and Reduction technology. For heavy-heavy duty applications where high torque and fuel economy are of prime concern, the Westport-Cycle{trademark} technology is in field trial. This technology incorporates High Pressure Direct Injection (HPDI{trademark}) of natural gas with a diesel pilot ignition source. Both fuels are delivered through a single, dual common rail injector. The operating cycle is entirely unthrottled and maintains the high compression ratio of a diesel engine. As a result of burning 95% natural gas rather than diesel fuel, NOx emissions are halved and PM is reduced by around 70%. High levels of EGR can be applied while maintaining high combustion efficiency, resulting in extremely low NOx potential. Some recent studies have indicated that DPF-equipped diesels emit less nanoparticles than some natural gas vehicles [1]. It must be understood that the ultrafine particles emitted from SI natural gas engines are generally accepted to consist predominantly of VOCs [2], and that lubricating oil is a major contributor. Fitting an oxidation catalyst to the natural gas engine leads to a reduction in nanoparticles emissions in comparison to engines without aftertreatment [2,3,4]. In 2001, the Cummins Westport Plus technology was introduced with the C Gas Plus engine, a popular choice for transit bus applications. This incorporates drive by wire, fully integrated, closed loop electronic controls and a standard oxidation catalyst for all applications. The B Gas Plus and the B Propane Plus engines, with application in shuttle and school buses were launched in 2002 and 2003. The gas-specific oxidation catalyst operates in concert with an optimized ring-pack and liner combination to reduce total particulate mass below 0.01g/bhphr, combat ultrafine particles and control VOC emissions.

Feasibility investigation of the giromill for generation of electrical power  

DOE Green Energy (OSTI)

The cyclogiro computer program, obtained from Prof. H. C. Larsen of the United States Air Force Institute of Technology, was modified to incorporate computation of blade loads for the normal operating and gust loading conditions. The program was also changed to allow computation of the effects of smoothing the blade rock angles in the region where they experienced large oscillations due to passing through a vortex shed by the previous blade. Using this program the various effects of rotor geometric parameters were investigated. Giromill configuration design concepts were explored. A baseline concept was adopted having an upper structural triangular tower extending through the lower support tower and supported by two main rotor bearings. Twenty-one different Giromill systems covering a power range of 120, 500 and 1500 kW were then synthesized. These were structurally analyzed and sized. An automatic electronic control concept built around existing equipment and employing state of the art techniques was developed. Preliminary cost estimates for generating electrical power from the Giromill systems were completed. Cost estimating relationships of the major items of equipment were formulated. 10 references.

Hurricane Katrina Wind Investigation Report  

SciTech Connect

This investigation of roof damage caused by Hurricane Katrina is a joint effort of the Roofing Industry Committee on Weather Issues, Inc. (RICOWI) and the Oak Ridge National Laboratory/U.S. Department of Energy (ORNL/DOE). The Wind Investigation Program (WIP) was initiated in 1996. Hurricane damage that met the criteria of a major windstorm event did not materialize until Hurricanes Charley and Ivan occurred in August 2004. Hurricane Katrina presented a third opportunity for a wind damage investigation in August 29, 2005. The major objectives of the WIP are as follows: (1) to investigate the field performance of roofing assemblies after major wind events; (2) to factually describe roofing assembly performance and modes of failure; and (3) to formally report results of the investigations and damage modes for substantial wind speeds The goal of the WIP is to perform unbiased, detailed investigations by credible personnel from the roofing industry, the insurance industry, and academia. Data from these investigations will, it is hoped, lead to overall improvement in roofing products, systems, roofing application, and durability and a reduction in losses, which may lead to lower overall costs to the public. This report documents the results of an extensive and well-planned investigative effort. The following program changes were implemented as a result of the lessons learned during the Hurricane Charley and Ivan investigations: (1) A logistics team was deployed to damage areas immediately following landfall; (2) Aerial surveillance--imperative to target wind damage areas--was conducted; (3) Investigation teams were in place within 8 days; (4) Teams collected more detailed data; and (5) Teams took improved photographs and completed more detailed photo logs. Participating associations reviewed the results and lessons learned from the previous investigations and many have taken the following actions: (1) Moved forward with recommendations for new installation procedures; (2) Updated and improved application guidelines and manuals from associations and manufacturers; (3) Launched certified product installer programs; and (4) Submitted building code changes to improve product installation. Estimated wind speeds at the damage locations came from simulated hurricane models prepared by Applied Research Associates of Raleigh, North Carolina. A dynamic hurricane wind field model was calibrated to actual wind speeds measured at 12 inland and offshore stations. The maximum estimated peak gust wind speeds in Katrina were in the 120-130 mph range. Hurricane Katrina made landfall near Grand Isle, Louisiana, and traveled almost due north across the city of New Orleans. Hurricane winds hammered the coastline from Houma, Louisiana, to Pensacola, Florida. The severe flooding problems in New Orleans made it almost impossible for the investigating teams to function inside the city. Thus the WIP investigations were all conducted in areas east of the city. The six teams covered the coastal areas from Bay Saint Louis, Mississippi, on the west to Pascagoula, Mississippi, on the east. Six teams involving a total of 25 persons documented damage to both low slope and steep slope roofing systems. The teams collected specific information on each building examined, including type of structure (use or occupancy), wall construction, roof type, roof slope, building dimensions, roof deck, insulation, construction, and method of roof attachment. In addition, the teams noted terrain exposure and the estimated wind speeds at the building site from the Katrina wind speed map. With each team member assigned a specific duty, they described the damage in detail and illustrated important features with numerous color photos. Where possible, the points of damage initiation were identified and damage propagation described. Because the wind speeds in Katrina at landfall, where the investigations took place, were less than code-specified design speeds, one would expect roof damage to be minimal. One team speculated that damage to all roofs in the area they examined was les

Rope and the art of knot-tying in the seafaring of the ancient Eastern Mediterranean  

E-Print Network (OSTI)

Fibers woven into cords or ropes and tied together with knots form one of mankind's earliest tools. When he first went out onto the water on anything more sophisticated than a simple paddle-driven dugout canoe he had to have done so with the assistance of some type of cordage. He may have needed a line tied around a stone that would serve as an anchor, a line to retrieve.his fishing spear, and a line to moor his craft on the beach. And soon he would need lines to hold a mast erect so he could raise a sail. In fact, no waterborne vessel, in ancient times, as today, could function without rope. As ships got larger and more complicated, the requirement for many different types and sizes of cordage became increasingly important. Depictions of seagoing vessels from the ancient eastern Mediterranean-Egyptian, Greek, Phoenician, or Roman--give some idea of the great quantities of cordage that would have been required to keep these ships at sea. Yet, when rope has been found on ancient shipwrecks, or in other nautical contexts, those examples have received comparatively little attention. Likewise, the overall subjects of the making of rope and the art of knot-tying in the ancient world, both without which ships could not have set sail, have received little attention. Evidence from antiquity that can open these subjects up to the modern world does exist. The Greek and Roman writers reveal a great deal about rope, and the materials used in its manufacture, although they are less open about knots. Ancient artists were less revealing with specific detail on rope and knots, but there is some information there. Archaeological remains of ancient rope are found on many shipwrecks and, while it occurs less often, a few knots have also been found on ancient sites. This thesis is a review of this material from the ancient world. It will provide insight into an important, but little known subject, and will add to our understanding of seafaring in the Mediterranean area during antiquity.

Bypassing the learning curve in permanent seed implants using state-of-the-art technology  

SciTech Connect

Purpose: The aim of this study was to demonstrate, based on clinical postplan dose distributions, that technology can be used efficiently to eliminate the learning curve associated with permanent seed implant planning and delivery. Methods and Materials: Dose distributions evaluated 30 days after the implant of the initial 22 consecutive patients treated with permanent seed implants at two institutions were studied. Institution 1 (I1) consisted of a new team, whereas institution 2 (I2) had performed more than 740 preplanned implantations over a 9-year period before the study. Both teams had adopted similar integrated systems based on three-dimensional (3D) transrectal ultrasonography, intraoperative dosimetry, and an automated seed delivery and needle retraction system (FIRST, Nucletron). Procedure time and dose volume histogram parameters such as D90, V100, V150, V200, and others were collected in the operating room and at 30 days postplan. Results: The average target coverage from the intraoperative plan (V100) was 99.4% for I1 and 99.9% for I2. D90, V150, and V200 were 191.4 Gy (196.3 Gy), 75.3% (73.0%), and 37.5% (34.1%) for I1 (I2) respectively. None of these parameters shows a significant difference between institutions. The postplan D90 was 151.2 Gy for I1 and 167.3 Gy for I2, well above the 140 Gy from the Stock et al. analysis, taking into account differences at planning, results in a p value of 0.0676. The procedure time required on average 174.4 min for I1 and 89 min for I2. The time was found to decrease with the increasing number of patients. Conclusion: State-of-the-art technology enables a new brachytherapy team to obtain excellent postplan dose distributions, similar to those achieved by an experienced team with proven long-term clinical results. The cost for bypassing the usual dosimetry learning curve is time, with increasing team experience resulting in shorter treatment times.

State-of-the-Art Highly Insulating Window Frames - Research and Market Review  

DOE Green Energy (OSTI)

This document reports the findings of a market and research review related to state-of-the-art highly insulating window frames. The market review focuses on window frames that satisfy the Passivhaus requirements (window U-value less or equal to 0.8 W/m{sup 2}K ), while other examples are also given in order to show the variety of materials and solutions that may be used for constructing window frames with a low thermal transmittance (U-value). The market search shows that several combinations of materials are used in order to obtain window frames with a low U-value. The most common insulating material seems to be Polyurethane (PUR), which is used together with most of the common structural materials such as wood, aluminum, and PVC. The frame research review also shows examples of window frames developed in order to increase the energy efficiency of the frames and the glazings which the frames are to be used together with. The authors find that two main tracks are used in searching for better solutions. The first one is to minimize the heat losses through the frame itself. The result is that conductive materials are replaced by highly thermal insulating materials and air cavities. The other option is to reduce the window frame area to a minimum, which is done by focusing on the net energy gain by the entire window (frame, spacer and glazing). Literature shows that a window with a higher U-value may give a net energy gain to a building that is higher than a window with a smaller U-value. The net energy gain is calculated by subtracting the transmission losses through the window from the solar energy passing through the windows. The net energy gain depends on frame versus glazing area, solar factor, solar irradiance, calculation period and U-value. The frame research review also discusses heat transfer modeling issues related to window frames. Thermal performance increasing measures, surface modeling, and frame cavity modeling are among the topics discussed. The review shows that the current knowledge gives the basis for improving the calculation procedures in the calculation standards. At the same time it is room for improvement within some areas, e.g. to fully understand the natural convection effects inside irregular vertical frame cavities (jambs) and ventilated frame cavities.

End-of-life vehicle recycling : state of the art of resource recovery from shredder residue.  

Science Conference Proceedings (OSTI)

Each year, more than 50 million vehicles reach the end of their service life throughout the world. More than 95% of these vehicles enter a comprehensive recycling infrastructure that includes auto parts recyclers/dismantlers, remanufacturers, and material recyclers (shredders). Today, about 75% of automotive materials are profitably recycled via (1) parts reuse and parts and components remanufacturing and (2) ultimately by the scrap processing (shredding) industry. The process by which the scrap processors recover metal scrap from automobiles involves shredding the obsolete automobiles, along with other obsolete metal-containing products (such as white goods, industrial scrap, and demolition debris), and recovering the metals from the shredded material. The single largest source of recycled ferrous scrap for the iron and steel industry is obsolete automobiles. The non-metallic fraction that remains after the metals are recovered from the shredded materials (about 25% of the weight of the vehicle)--commonly called shredder residue--is disposed of in landfills. Over the past 10 to 15 years, a significant amount of research and development has been undertaken to enhance the recycle rate of end-of-life vehicles (ELVs), including enhancing dismantling techniques and improving remanufacturing operations. However, most of the effort has focused on developing technology to recover materials, such as polymers, from shredder residue. To make future vehicles more energy efficient, more lighter-weight materials--primarily polymers and polymer composites--will be used in manufacturing these vehicles. These materials increase the percentage of shredder residue that must be disposed of, compared with the percentage of metals. Therefore, as the complexity of automotive materials and systems increases, new technologies will be required to sustain and maximize the ultimate recycling of these materials and systems at end-of-life. Argonne National Laboratory (Argonne), in cooperation with the Vehicle Recycling Partnership (VRP) and the American Plastics Council (APC), is working to develop technology for recycling materials from shredder residue. Several other organizations worldwide are also working on developing technology for recycling shredder residue. Without a commercially viable shredder industry, our nation may face greater environmental challenges and a decreased supply of quality scrap and be forced to turn to primary ores for the production of finished metals. This document presents a review of the state of the art in shredder residue recycling. Available technologies and emerging technologies for the recycling of materials from shredder residue are discussed.

End-of-life vehicle recycling : state of the art of resource recovery from shredder residue.  

Science Conference Proceedings (OSTI)

Each year, more than 25 million vehicles reach the end of their service life throughout the world, and this number is rising rapidly because the number of vehicles on the roads is rapidly increasing. In the United States, more than 95% of the 10-15 million scrapped vehicles annually enter a comprehensive recycling infrastructure that includes auto parts recyclers/dismantlers, remanufacturers, and material recyclers (shredders). Today, over 75% of automotive materials, primarily the metals, are profitably recycled via (1) parts reuse and parts and components remanufacturing and (2) ultimately by the scrap processing (shredding) industry. The process by which the scrap processors recover metal scrap from automobiles involves shredding the obsolete automobile hulks, along with other obsolete metal-containing products (such as white goods, industrial scrap, and demolition debris), and recovering the metals from the shredded material. The single largest source of recycled ferrous scrap for the iron and steel industry is obsolete automobiles. The non-metallic fraction that remains after the metals are recovered from the shredded materials - commonly called shredder residue - constitutes about 25% of the weight of the vehicle, and it is disposed of in landfills. This practice is not environmentally friendly, wastes valuable resources, and may become uneconomical. Therefore, it is not sustainable. Over the past 15-20 years, a significant amount of research and development has been undertaken to enhance the recycle rate of end-of-life vehicles, including enhancing dismantling techniques and improving remanufacturing operations. However, most of the effort has been focused on developing technology to separate and recover non-metallic materials, such as polymers, from shredder residue. To make future vehicles more energy efficient, more lightweighting materials - primarily polymers, polymer composites, high-strength steels, and aluminum - will be used in manufacturing these vehicles. Many of these materials increase the percentage of shredder residue that must be disposed of, compared with the percentage of metals that are recovered. In addition, the number of hybrid vehicles and electric vehicles on the road is rapidly increasing. This trend will also introduce new materials for disposal at the end of their useful lives, including batteries. Therefore, as the complexity of automotive materials and systems increases, new technologies will be required to sustain and maximize the ultimate recycling of these materials and systems. Argonne National Laboratory (Argonne), the Vehicle Recycling Partnership, LLC. (VRP) of the United States Council for Automotive Research, LLC. (USCAR), and the American Chemistry Council-Plastics Division (ACC-PD) are working to develop technology for recovering materials from end-of-life vehicles, including separating and recovering polymers and residual metals from shredder residue. Several other organizations worldwide are also working on developing technology for recycling materials from shredder residue. Without a commercially viable shredder industry, our nation and the world will most likely face greater environmental challenges and a decreased supply of quality scrap, and thereby be forced to turn to primary ores for the production of finished metals. This will result in increased energy consumption and increased damage to the environment, including increased greenhouse gas emissions. The recycling of polymers, other organics, and residual metals in shredder residue saves the equivalent of over 23 million barrels of oil annually. This results in a 12-million-ton reduction in greenhouse gas emissions. This document presents a review of the state-of-the-art in the recycling of automotive materials.

This study was undertaken to conduct a preliminary analysis of the state of the art of two technologies, robotics and precision engineering, and to evaluate their potential for improved energy utilization in the pulp, paper, and related energy consuming processes. Activity in the robotics field is growing rapidly, most activity being related to the development of smart robots rather than to systems. There is a broad base of support, both in industry and the universities, for upgrading robot machine capabilities. A large part of that support is associated with visualization and tactile sensors which facilitate assembly, placement, inspection, and tracking. Progress in this area is relatively rapid and development times are short for specifically engineered applications. The critical path in the development of robotic systems lies in the generation of reliable sensor signals. Robotic systems require a broad spectrum of sensors from which hierarchical logic systems can draw decision making information. This requirement resulted in the establishment of a program at the National Bureau of Standards which is attempting to develop a spectrum of sensor capabilities. Such sensors are applicable to robotic system automatic process control in a variety of energy-intensive industries. Precision engineering is defined as the generation or manufacture of components wherein geometry, dimension, and surface finish are controlled to within several hundred Angstroms in single point turning operations. Investigation into the state of the art of precision engineering in the United States finds that this capability exists in several national laboratories and is intended to be used exclusively for the development of weapons. There is an attempt at the present time by Lawrence Livermore Laboratory to expand its capability into industry. Several corporations are now beginning to develop equipment to support the precision engineering field.

Computer simulation models relevant to ground water contamination from EOR or other fluids - state-of-the-art  

SciTech Connect

Ground water contamination is a serious national problem. The use of computers to simulate the behavior of fluids in the subsurface has proliferated extensively over the last decade. Numerical models are being used to solve water supply problems, various kinds of enertgy production problems, and ground water contamination problems. Modeling techniques have progressed to the point that their accuracy is only limited by the modeller's ability to describe the reservoir in question and the heterogeneities therein. Pursuant to the Task and Milestone Update of Project BE3A, this report summarizes the state of the art of computer simulation models relevant to contamination of ground water by enhanced oil recovery (EOR) chemicals and/or waste fluids. 150 refs., 6 tabs.

Steps to an Ecology of Networked Knowledge and Innovation: Enabling new forms of collaboration among sciences, engineering, arts, and design  

E-Print Network (OSTI)

The final White Papers (posted at http://seadnetwork.wordpress.com/white-paper- abstracts/final-white-papers/) represent a spectrum of interests in advocating for transdisciplinarity among arts, sciences, and technologies. All authors submitted plans of action and identified stakeholders they perceived as instrumental in carrying out such plans. The individual efforts led to an international scope. One of the important characteristics of this collection is that the papers do not represent a collective aim toward an explicit initiative. Rather, they offer a broad array of views on barriers faced and prospective solutions. In summary, the collected White Papers and associated Meta- analyses began as an effort to take the pulse of the SEAD community as broadly as possible. The ideas they generated provide a fruitful basis for gauging trends and challenges in facilitating the growth of the network and implementing future SEAD initiatives.

A Critical Review of the State-of-the-Art in Autonomous Land Vehicle Systems and Technology  

DOE Green Energy (OSTI)

This report describes the current state-of-the-art in Autonomous Land Vehicle (ALV) systems and technology. Five functional technology areas are identified and addressed. For each a brief, subjective, preface is first provided which envisions the necessary technology for the deployment of an operational ALV system. Subsequently, a detailed literature review is provided to support and elaborate these views. It is further established how these five technology areas fit together as a functioning whole. The essential conclusion of this report is that the necessary sensors, algorithms and methods to develop and demonstrate an operationally viable all-terrain ALV already exist and could be readily deployed. A second conclusion is that the successful development of an operational ALV system will rely on an effective approach to systems engineering. In particular, a precise description of mission requirements and a clear definition of component functionality is essential.

Field investigation of keyblock stability  

SciTech Connect

Discontinuities in a rock mass can intersect an excavation surface to form discrete blocks (keyblocks) which can be unstable. This engineering problem is divided into two parts: block identification, and evaluation of block stability. One stable keyblock and thirteen fallen keyblocks were observed in field investigations at the Nevada Test Site. Nine blocks were measured in detail sufficient to allow back-analysis of their stability. Measurements included block geometry, and discontinuity roughness and compressive strength. Back-analysis correctly predicted stability or failure in all but two cases. These two exceptions involved situations that violated the stress assumptions of the stability calculations. Keyblock faces correlated well with known joint set orientations. The effect of tunnel orientation on keyblock frequency was apparent. Back-analysis of physical models successfully predicted block pullout force for two-dimensional models of unit thickness. Two-dimensional (2D) and three-dimensional (3D) analytic models for the stability of simple pyramidal keyblocks were examined. Calculated stability is greater for 3D analyses than for 2D analyses. Calculated keyblock stability increases with larger in situ stress magnitudes, larger lateral stress ratios, and larger shear strengths. Discontinuity stiffness controls block displacement more strongly than it does stability itself. Large keyblocks are less stable than small ones, and stability increases as blocks become more slender. Rock mass temperature decreases reduce the confining stress magnitudes and can lead to failure. The pattern of stresses affecting each block face explains conceptually the occurrence of pyramidal keyblocks that are truncated near their apex.

State-of-the-art low-cost solar reflector materials  

SciTech Connect

Solar thermal technologies generate power by concentrating sunlight with large mirrors. The National Renewable Energy Laboratory (NREL) is working with industrial partners to develop the optical reflector materials needed for the successful deployment of this technology. The reflector materials must be low in cost and maintain high specular reflectance for extended lifetimes in severe outdoor environments. Currently, the best candidate materials for solar mirrors are silver-coated low-iron glass and silvered polymer films. Polymer reflectors are lighter in weight, offer greater flexibility in system design, and have the potential for lower cost than glass mirrors. In parallel with collaborative activities, several innovative candidate reflector-material constructions were investigated at NREL. The low-cost material requirement necessitates manufacturing compatible with mass-production techniques. Future cooperative efforts with the web-coating industry offers the promise of exciting new alternative materials and the potential for dramatic cost savings in developing advanced solar reflector materials.

EVALUATION OF STATE-OF-THE-ART MANIPULATORS AND REQUIREMENTS FOR DOE ROBOTICS APPLICATIONS  

Science Conference Proceedings (OSTI)

This report provides an overview of applications within the DOE complex which could benefit from the use of modular robotics technology during remediation operations. Each application area contains one or more specific tasks which are presently conducted by humans under hazardous conditions or which are deemed highly impractical, or are altogether impossible without automation. Five major areas were investigated for specific needs with respect to automation. Information was collected on Mixed Waste Operations, Contaminant Automated Analysis, Tanks, Decontamination and Dismantlement and Automated Plutonium Processing. During this investigation, information was gathered from available literature, telephone interviews with informed personnel and on-site visits. This data serves to provide design requirements and guidelines for the design of a family of modular actuators, which will be used to construct manipulators suited to each task. In addition, a survey of existing modular manipulator designs is presented. This survey addresses modular manipulators developed inside government labs and in universities for such applications as space exploration or controls research. It also addresses efforts at commercially viable industrial manipulators which have been built. This survey of robotic systems provides the reader with a glimpse into what technology currently exists in the way of modular manipulator automation and, to a degree, where this technology may be applicable or, more often, where these systems are unsuited to EM applications. From the information gathered during this study, it is possible to sufficiently define the requirements of one manipulator system which can be used to conduct automated transfer operations within Plutonium gloveboxes. This manipulator will be constructed from ARM Automation actuator modules and will provide this application with a viable option for automation within these gloveboxes. The design issues surrounding this manipulator and its specifications are discussed in the final portion of this report.

Tribochemical investigation of microelectronic materials  

E-Print Network (OSTI)

To achieve efficient planarization with reduced device dimensions in integrated circuits, a better understanding of the physics, chemistry, and the complex interplay involved in chemical mechanical planarization (CMP) is needed. The CMP process takes place at the interface of the pad and wafer in the presence of the fluid slurry medium. The hardness of Cu is significantly less than the slurry abrasive particles which are usually alumina or silica. It has been accepted that a surface layer can protect the Cu surface from scratching during CMP. Four competing mechanisms in materials removal have been reported: the chemical dissolution of Cu, the mechanical removal through slurry abrasives, the formation of thin layer of Cu oxide and the sweeping surface material by slurry flow. Despite the previous investigation of Cu removal, the electrochemical properties of Cu surface layer is yet to be understood. The motivation of this research was to understand the fundamental aspects of removal mechanisms in terms of electrochemical interactions, chemical dissolution, mechanical wear, and factors affecting planarization. Since one of the major requirements in CMP is to have a high surface finish, i.e., low surface roughness, optimization of the surface finish in reference to various parameters was emphasized. Three approaches were used in this research: in situ measurement of material removal, exploration of the electropotential activation and passivation at the copper surface and modeling of the synergistic electrochemical-mechanical interactions on the copper surface. In this research, copper polishing experiments were conducted using a table top tribometer. A potentiostat was coupled with this tribometer. This combination enabled the evaluation of important variables such as applied pressure, polishing speed, slurry chemistry, pH, materials, and applied DC potential. Experiments were designed to understand the combined and individual effect of electrochemical interactions as well as mechanical impact during polishing. Extensive surface characterization was performed with AFM, SEM, TEM and XPS. An innovative method for direct material removal measurement on the nanometer scale was developed and used. Experimental observations were compared with the theoretically calculated material removal rate values. The synergistic effect of all of the components of the process, which result in a better quality surface finish was quantitatively evaluated for the first time. Impressed potential during CMP proved to be a controlling parameter in the material removal mechanism. Using the experimental results, a model was developed, which provided a practical insight into the CMP process. The research is expected to help with electrochemical material removal in copper planarization with low-k dielectrics.

Low temperature thermal energy storage: a state-of-the-art survey  

DOE Green Energy (OSTI)

The preliminary version of an analysis of activities in research, development, and demonstration of low temperature thermal energy storage (TES) technologies having applications in renewable energy systems is presented. Three major categories of thermal storage devices are considered: sensible heat; phase change materials (PCM); and reversible thermochemical reactions. Both short-term and annual thermal energy storage technologies based on prinicples of sensible heat are discussed. Storage media considered are water, earth, and rocks. Annual storage technologies include solar ponds, aquifers, and large tanks or beds of water, earth, or rocks. PCM storage devices considered employ salt hydrates and organic compounds. The sole application of reversible chemical reactions outlined is for the chemical heat pump. All program processes from basic research through commercialization efforts are investigated. Nongovernment-funded industrial programs and foreign efforts are outlined as well. Data describing low temperature TES activities are presented also as project descriptions. Projects for all these programs are grouped into seven categories: short-term sensible heat storage; annual sensible heat storage; PCM storage; heat transfer and exchange; industrial waste heat recovery and storage; reversible chemical reaction storage; and models, economic analyses, and support studies. Summary information about yearly funding and brief descriptions of project goals and accomplishments are included.

Thermoelectric Alloys and Devices for Radioisotope Space Power Systems: State of the Art and Current Developments  

SciTech Connect

Lead telluride and silicon germanium type alloys have served over the past several decades as the preferred thermoelectric conversion materials for U. S. radioisotope thermoelectric generator (RTG) power systems for planetary deep space exploration missions. The Pioneer missions to Jupiter and Jupiter/Saturn and the Viking Mars Lander missions employed TAGS-2N (lead and germanium telluride derivatives) power conversion devices. Since 1976, silicon germanium (SiGe) alloys, incorporated into the unicouple device, have evolved as the thermoelectric materials of choice for U. S. RTG powered space missions. These include the U. S. Air Force Lincoln Experimental Satellites 8 & 9 for communications, in 1976, followed in 1977 by the National Aeronautics and Space Administration Voyager 1 and 2 planetary missions. In 1989, advanced SiGe RTGs were used to power the Galileo exploration of Jupiter and, in 1990, will be used to power the Ulysses investigation of the Sun. In addition, SiGe technology has been chosen to provide RTG power for the 1995 Comet Rendezvous and Asteroid Flyby mission and the 1996 Cassini Saturn orbiter mission. Summaries of the flight performance data for these systems are presented.; Current U. S. Department of Energy thermoelectric development activities include (1) the development of conversion devices based on hi-density, close packed couple arrays and (2) the development of improved performance silicon germanium type thermoelectric materials. The silicon germanium type "multicouple", being developed in conjunction with the Modular RTG program, is discussed in a companion paper. A lead telluride type close-packed module, discussed herein, offers the promise of withstanding high velocity impacts and, thus, is a candidate for a Mars Penetrator application.; Recent projects sponsored by the U. S. Department of Energy, including the Improved Thermoelectric Materials and Modular Radioisotope Thermoelectric Generator programs, have shown that improvements in silicon germanium thermoelectric energy conversion capabilities of at least 50 percent can be achieved by tailoring the characteristics of the silicon germanium alloy materials and devices. This paper compares the properties and characteristics of the SiGe alloys now being developed with those used in the operational space power system.

State-of-the-art of liquid waste disposal for geothermal energy systems: 1979. Report PNL-2404  

SciTech Connect

The state-of-the-art of geothermal liquid waste disposal is reviewed and surface and subsurface disposal methods are evaluated with respect to technical, economic, legal, and environmental factors. Three disposal techniques are currently in use at numerous geothermal sites around the world: direct discharge into surface waters; deep-well injection; and ponding for evaporation. The review shows that effluents are directly discharged into surface waters at Wairakei, New Zealand; Larderello, Italy; and Ahuachapan, El Salvador. Ponding for evaporation is employed at Cerro Prieto, Mexico. Deep-well injection is being practiced at Larderello; Ahuachapan; Otake and Hatchobaru, Japan; and at The Geysers in California. All sites except Ahuachapan (which is injecting only 30% of total plant flow) have reported difficulties with their systems. Disposal techniques used in related industries are also reviewed. The oil industry's efforts at disposal of large quantities of liquid effluents have been quite successful as long as the effluents have been treated prior to injection. This study has determined that seven liquid disposal methods - four surface and three subsurface - are viable options for use in the geothermal energy industry. However, additional research and development is needed to reduce the uncertainties and to minimize the adverse environmental impacts of disposal. (MHR)

Probability based load criteria for the design of nuclear structures: a critical review of the state-of-the-art  

Science Conference Proceedings (OSTI)

Structures for nuclear power plant facilities must be designed to withstand safely and effectively all kinds of loads and load combinations that may be expected to occur during their lifetime. The traditional methods of structural design attempt to account for the inevitable variability in the loads, material strengths, in-service environments, and fabrication process, etc., through the use of safety factor, allowable stresses or load and resistance factors. These approaches may result in an unknown and nonuniform reliability because of the subjective manner in which the safety factors have been determined. The stochastic nature loads and the uncertainties in material properties dictate a probabilistic approach for a rational assessment of structural safety and performance. This report presents: an in-depth review of the state-of-the-art pertaining to probability-based analysis and design of civil engineering structures; basis for extending existing probability-based methods to seismic category I nuclear structures; and the availability of the pertinent data required to perform probabilistic analysis for seismic category I nuclear structures.

Experimental and theoretical investigations on the warm-up of a high-pressure mercury discharge lamp  

SciTech Connect

Modern high-pressure discharge lamps are forced to provide instant light and hot relight capabilities - if possible at lower power units. A detailed understanding of the warm-up of high-pressure discharge lamps is therefore required. Complex fluid model codes were developed for the past years including more and more processes like two-dimensional treatment of convection trying to provide a more comprehensive and consistent description of high-pressure discharge lamps. However, there is a lack of experimental data to examine the performance of these models. This work provides a very complete set of geometrical, electrical, spectroscopic, and thermographic data according to the warm-up of a high-pressure mercury discharge lamp that is compared to the results of a state of the art fluid code. Quantitative agreement is achieved for single parameters like wall temperatures. But the paper also reveals the need for further investigations and improvements of the code.

Geophysical Investigations of Archaeological Resources in Southern Idaho  

SciTech Connect

At the Idaho National Laboratory and other locations across southern Idaho, geophysical tools are being used to discover, map, and evaluate archaeological sites. A variety of settings are being explored to expand the library of geophysical signatures relevant to archaeology in the region. Current targets of interest include: prehistoric archaeological features in open areas as well as lava tube caves, historical structures and activity areas, and emigrant travel paths. We draw from a comprehensive, state of the art geophysical instrumentation pool to support this work. Equipment and facilities include ground penetrating radar, electromagnetic and magnetic sensors, multiple resistivity instruments, advanced positioning instrumentation, state of the art processing and data analysis software, and laboratory facilities for controlled experiments.

Investigation of the Degradation Mechanisms of a Variety of Organic Photovoltaic Devices by Combination of Imaging Techniques - The ISOS-3 Inter-Laboratory Collaboration  

DOE Green Energy (OSTI)

The investigation of degradation of seven distinct sets (with a number of individual cells of n {>=} 12) of state of the art organic photovoltaic devices prepared by leading research laboratories with a combination of imaging methods is reported. All devices have been shipped to and degraded at Riso DTU up to 1830 hours in accordance with established ISOS-3 protocols under defined illumination conditions. Imaging of device function at different stages of degradation was performed by laser-beam induced current (LBIC) scanning; luminescence imaging, specifically photoluminescence (PLI) and electroluminescence (ELI); as well as by lock-in thermography (LIT). Each of the imaging techniques exhibits its specific advantages with respect to sensing certain degradation features, which will be compared and discussed here in detail. As a consequence, a combination of several imaging techniques yields very conclusive information about the degradation processes controlling device function. The large variety of device architectures in turn enables valuable progress in the proper interpretation of imaging results -- hence revealing the benefits of this large scale cooperation in making a step forward in the understanding of organic solar cell aging and its interpretation by state-of-the-art imaging methods.

Investigation of a regenerative damping concept  

E-Print Network (OSTI)

This thesis presents a justification for the study of regenerative damping, a general statement of the regenerative damping problem, and a detailed analysis of a specific proposed solution to the regenerative damping problem. Improvement in the efficiency of many physical systems is realized by the incorporation of regenerative devices, and all devices which dissipate power are candidates for investigation as regenerative systems. The viscous damper is a dissipative device which may be suitable for energy regeneration and is therefore investigated as such. Regenerative damping involves storing the power normally dissipated by a passive viscous damper. This task is accomplished by constructing a system which connects an energy storing device to the device being damped. The connecting system must efficiently transfer power from the device being damped to the storage device while simultaneously meeting the operating impedance of the storage device and producing a desired damping impedance. Many physical systems can accomplish this task, and the variable linear transmission is proposed for further investigation. Mathematical, graphical, and computer models are constructed to study the variable linear transmission. These models directly indicate the control strategies necessary to operate the device as a regenerative damper. Studies of kinematic performance and efficiency of the proposed damper indicate that a strong connection exists between the goodness of the performance of the proposed device as a damper and its efficiency. Both of these issues are directly related to the strategy used in the active control of the device.Results indicate that in its ideal state, the proposed damper exactly solves the problem of regenerative damping. For the non-ideal operation of the device, which includes the effects of system actuation dynamics, the performance looks promising but will require more investigation into optimal control strategies. Overall, the prospects for realizing regenerative damping are shown to be positive, and further investigation of this subject is encouraged.

CRADA Final Report for CRADA Number ORNL98-0521 : Development of an Electric Bus Inverter Based on ORNL Auxiliary Resonant Tank (ART) Soft-Switching Technology  

SciTech Connect

The Power Electronics and Electric Machinery Research Center (PEEMRC) of Oak Ridge National Laboratory (ORNL) has for many years been developing technologies for power converters for motor drives and many other applications. Some of the research goals are to improve efficiency and reduce audible and electromagnetic interference noise generation for inverters and the driven loads. The converters are being required to produce more power with reduced weight and volume, which requires improvements in heat removal from the electronics, as well as improved circuit designs that have fewer electrical losses. PEEMRC has recently developed and patented a soft-switching inverter topology called an Auxiliary Resonant Tank (ART), and this design has been tested and proven at ORNL using a 10-kW laboratory prototype. The objective of this project was to develop, test, and install the ART inverter technology in an electric transit bus with the final goal of evaluating performance of the ORNL inverter under field conditions in a vehicle. A scaled-up inverter with the capacity to drive a 22-e bus was built based on the 10-kW ORNL laboratory prototype ART soft-switching inverter. Most (if not all) commercially available inverters for traction drive and other applications use hard-switching inverters. A Cooperative Research and Development Agreement was established with the Chattanooga Area Regional Transit Authority (CARTA), the Electric Transit Vehicle Institute (ETVI), and Advanced Vehicle Systems (AVS), all of Chattanooga, along with ORNL. CARTA, which maintains and operates the public transit system in Chattanooga, provided an area for testing the vehicle alongside other similar vehicles in the normal operating environment. ETVI offers capabilities in standardized testing and reporting and also provides exposure in the electric transit vehicle arena for ORNL's technologies. The third Chattanooga partner, (AVS) manufactures all-electric and hybrid electric transit buses using inverter drive systems from several manufacturers. AVS provided help in field installation, and parts for laboratory testing. A 100-kW field-ready unit was developed, tested in an ORNL laboratory, and installed and successfully operated in a CARTA bus in Chattanooga. The tests on the vehicle were performed at a CARTA maintenance facility and at a l-mile test track in Chattanooga managed by CARTA.

Stable isotope investigations of chlorinated aliphatic hydrocarbons.  

Science Conference Proceedings (OSTI)

Stable isotope ratio measurements for carbon (C) and chlorine (Cl) can be used to elucidate the processes affecting transformation and transportation of chlorinated aliphatic hydrocarbons (CAHs) in the environment. Methods recently developed in our laboratory for isotopic analysis of CAHs have been applied to laboratory measurements of the kinetic isotope effects associated with aerobic degradation of dichloromethane (DCM) and with both anaerobic and aerobic cometabolic degradation of trichlomethene (TCE) in batch and column microbial cultures. These experimental determinations of fractionation factors are crucial for understanding the behavior of CAHs in complex natural systems, where the extent of biotransformation can be masked by dispersion and volatilization. We have also performed laboratory investigations of kinetic isotope effects accompanying evaporation of CAHs, as well as field investigations of natural attenuation and in situ remediation of CAHs in a number of contaminated shallow aquifers at sites operated by the federal government and the private sector.

Investigating Inflation Persistence in the ACF Domain ?  

E-Print Network (OSTI)

This paper investigates inflation persistence in a panel of 20 OECD economies by means of the sample AutoCorrelation Functions (ACFs). We find that the inflation empirical ACFs display a common behavior across countries, characterized by long-lasting fluctuations around a potentially time-varying mean. Recent contributions in the macroeconomic literature on heterogeneity in price setting and aggregation offer theoretical support to our findings. Moreover, the empirical ACFs are well approximated by a nonlinear and long memory time series process (ACT) which improves over standard linear autoregressive processes. This improvement is robust to variations of the investigated sample. Using the estimated parameters of the ACT functional form as a measure of inflation persistence, we find a negative correlation between persistence and inflation targeting. JEL classification: E50, C22.

Investigating Extreme Investigating Extreme Ultraviolet Lithography Mask Defects Investigating Extreme Ultraviolet Lithography Mask Defects Print Wednesday, 28 July 2010 00:00 Since the 1970s, the semiconductor industry has strived to shrink the cost and size of circuit patterns printed onto computer chips in accordance with Moore's law, doubling the number of transistors on a computer's central processing unit (CPU) every two years. The introduction of extreme ultraviolet (EUV) lithography, printing chips using 13-nm-wavelength light, opens the way to future generations of smaller, faster, and cheaper semiconductors. EUV lithography relies on specialized lenses made of curved mirrors with reflective coatings called multilayers to print patterns with high resolution. One special flat mirror called a mask is particularly sensitive to even the smallest imperfections. To better detect and characterize mask defects, scientists at Berkeley Lab worked with SEMATECH, an international semiconductor industry consortium, to create a unique Fresnel zone-plate microscope on Advanced Light Source Beamline 11.3.2 called the SEMATECH Berkeley Actinic Inspection Tool (AIT).

Clean slate corrective action investigation plan  

SciTech Connect

The Clean Slate sites discussed in this report are situated in the central portion of the Tonopah Test Range (TTR), north of the Nevada Test Site (NTS) on the northwest portion of the Nellis Air Force Range (NAFR) which is approximately 390 kilometers (km) (240 miles [mi]) northwest of Las Vegas, Nevada. These sites were the locations for three of the four Operation Roller Coaster experiments. These experiments evaluated the dispersal of plutonium in the environment from the chemical explosion of a plutonium-bearing device. Although it was not a nuclear explosion, Operation Roller Coaster created some surface contamination which is now the subject of a corrective action strategy being implemented by the Nevada Environmental Restoration Project (NV ERP) for the U.S. Department of Energy (DOE). Corrective Action Investigation (CAI) activities will be conducted at three of the Operation Roller Coaster sites. These are Clean Slate 1 (CS-1), Clean Slate 2 (CS-2), and Clean Slate 3 (CS-3) sites, which are located on the TTR. The document that provides or references all of the specific information relative to the various investigative processes is called the Corrective Action Investigation Plan (CAIP). This CAIP has been prepared for the DOE Nevada Operations Office (DOE/NV) by IT Corporation (IT).

JACK DÉLANO’S (1914-1997) BURUNDANGA OR CANTATA ANTILLANA: AN ART-MUSIC PORTRAYAL OF LUIS PALÉS MATOS’S (1898-1959) BLACK CARIBBEAN  

E-Print Network (OSTI)

This is an analytical study of Burundanga or Cantata Antillana by Jack Délano (1914-1997). One of Délano’s most ambitious choral-orchestral compositions, Burundanga was completed in 1989 in response to a commission from the Institute of Puerto Rican Culture and is based on Luis Palés Matos’s (1898-1959) extravagant and elaborate poem Canción festiva para ser llorada (A Festive Song to be Wept). Burundanga stands at the foreground of Puerto Rican art-music in the twentieth century. With its neoclassical language and integration of Caribbean folkloric material, it emerges as a unique reflection of the highly complex geographical, social, cultural and musical reality of Puerto Rico and the Antilles. The analysis underscores the relationships between the textual images and the musical resources employed in their setting, focusing on the composition’s formal, melodic, harmonic, rhythmic, orchestrational and expressive elements. It also discerns particular methods by which the composer utilized and adapted Afro-

Onset and Subsequent Transient Phenomena of Liquid Loading in Gas Wells: Experimental Investigation Using a Large Scale Flow Loop  

E-Print Network (OSTI)

Liquid loading in gas wells is generally described as the inability of the well to lift the co-produced liquids up the tubing, which may ultimately kill the well. There is a lack of dedicated models that can mimic the transient features that are typical of liquid loading. Improved characterization of liquid loading in gas wells and enhanced prediction of future well performance can be achieved from the measurements and analyses resulting from this project. An experimental investigation was carried out to study the onset of liquid loading and the subsequent transient phenomena, using a large scale flow loop to visualize two-phase flow regimes, and to measure pressure and liquid holdup along a 42-m long vertical tube. From this investigation, it is possible to conclude that liquid loading should not be characterized based on onset criteria alone, and that it may not be a wellbore-only problem, as it would seem that the reservoir also plays a key role in determining if/when/how liquid loading manifests itself. Additionally, the results from the experimental campaign were used to compare the performance of different wellbore flow simulators. State-of-the-art simulators do not seem to fully capture the nature of liquid loading in vertical tubes. A simplified model is roposed here to evaluate the liquid transport during the transition from one flow regime to another, during the loading sequence.

Investigation of optical methods for hydroyield measurements  

SciTech Connect

Two fiber optic techniques, the Linear Resistive Ladder (LRL) and the piezo-driven LED arrangement, were investigated and successfully demonstrated in the laboratory to be capable of being used for hydroyield measurements. Prototype linear arrangements for each of the above methods were constructed and placed in a designed UGT. The piezo-driven LED method appears very attractive as it showed the potential for becoming an all passive, non-intrusive'' treaty verification method capable of functioning at stress levels ranging from less than 1Kbar to 100 Kbars. Other optical methods using fiber optics for detection mechanisms and signal transmissions were also conceptually examined. 11 figs.

Investigation of restricted baby Skyrme models  

Science Conference Proceedings (OSTI)

A restriction of the baby Skyrme model consisting of the quartic and potential terms only is investigated in detail for a wide range of potentials. Further, its properties are compared with those of the corresponding full baby Skyrme models. We find that topological (charge) as well as geometrical (nucleus/shell shape) features of baby Skyrmions are captured already by the soliton solutions of the restricted model. Further, we find a coincidence between the compact or noncompact nature of solitons in the restricted model, on the one hand, and the existence or nonexistence of multi-Skyrmions in the full baby Skyrme model, on the other hand.

(90377) SEDNA: INVESTIGATION OF SURFACE COMPOSITIONAL VARIATION  

Science Conference Proceedings (OSTI)

The dwarf planet (90377) Sedna is one of the most remote solar system objects accessible to investigations. To better constrain its surface composition and to investigate the possible heterogeneity of the surface of Sedna, several observations have been carried out at ESO-VLT with the powerful spectrometer SINFONI observing simultaneously the H and K bands. The analyzed spectra (obtained in 2005, 2007, and 2008) show a non-uniform spectral signature, particularly in the K band. Spectral modeling using the Shkuratov radiative transfer code for surface scattering has been performed using the various sets of data, including previous observations at visible wavelengths and photometry at 3.6 and 4.5 {mu}m by the Spitzer Space Telescope. The visible and near-infrared spectra can be modeled with organic materials (triton and titan tholin), serpentine, and H{sub 2}O ice in fairly significant amounts, and CH{sub 4}, N{sub 2}, and C{sub 2}H{sub 6} in varying trace amounts. One of the spectra obtained in 2005 October shows a different signature in the K band and is best modeled with CH{sub 3}OH in place of CH{sub 4}, with reduced amounts of serpentine and with the addition of olivine. The compositional surface heterogeneity can give input on the past history as well clues to the origin of this peculiar, distant object.

An investigation of the role of water on retrograde/condensation reactions and enhanced liquefaction yields  

SciTech Connect

Changes in coal structure that may occur during coal drying will be measured in order to determine the effects of coal drying on its reactivity toward liquefaction. Different methods for coal drying will be investigated to determine if drying can be accomplished without destroying coal reactivity toward liquefaction, thereby making coal drying a relatively economical and efficient method for coal pretreatment. Coal drying methods will include conventional thermal drying, microwave drying and chemical drying at low temperature. State-of-the-art solid-state nuclear magnetic resonance (NMR) techniques using combined rotation and multiple pulse spectroscopy (CRAMPS) and cross polarization with magic-angle spinning (CP/MAS) will be employed: (1) to measures changes in coal structure brought about by the different methods of drying and by low temperature oxidation, and (2) to obtain direct measurements of changes in the aromatic hydrogen-to-carbon ratio of the solid/semisolid material formed or remaining during pretreatment and the initial stages of liquefaction. The objectives for this quarter were to begin coal drying experiments using thermal, microwave, and chemical methods, and to begin coal liquefaction experiments on the dried coals. Three additional coal samples have been acquired. These are a Black Thunder Mine coal acquired from Arco Coal Co, and a Texas subC and Illinois No. 6 hvC acquired from the DOE coal sample bank at Penn State. The samples are listed as DECS-1 and DECS-2, respectively in the PSU sample bank. The ultimate and proximate analyses for all the samples are given in Table 1. Work on each of the subtasks is described in separate paragraphs.

Salmon Site Remedial Investigation Report, Exhibit 5  

Science Conference Proceedings (OSTI)

This Salmon Site Remedial Investigation Report provides the results of activities initiated by the U.S. Department of Energy (DOE) to determine if contamination at the Salmon Site poses a current or future risk to human health and the environment. These results were used to develop and evaluate a range of risk-based remedial alternatives. Located in Lamar County, Mississippi, the Salmon Site was used by the U.S. Atomic Energy Commission (predecessor to the DOE) between 1964 and 1970 for two nuclear and two gas explosions conducted deep underground in a salt dome. The testing resulted in the release of radionuclides into the salt dome. During reentry drilling and other site activities, liquid and solid wastes containing radioactivity were generated resulting in surface soil and groundwater contamination. Most of the waste and contaminated soil and water were disposed of in 1993 during site restoration either in the cavities left by the tests or in an injection well. Other radioactive wastes were transported to the Nevada Test Site for disposal. Nonradioactive wastes were disposed of in pits at the site and capped with clean soil and graded. The preliminary investigation showed residual contamination in the Surface Ground Zero mud pits below the water table. Remedial investigations results concluded the contaminant concentrations detected present no significant risk to existing and/or future land users, if surface institutional controls and subsurface restrictions are maintained. Recent sampling results determined no significant contamination in the surface or shallow subsurface. The test cavity resulting from the experiments is contaminated and cannot be economically remediated with existing technologies. The ecological sampling did not detect biological uptake of contaminants in the plants or animals sampled. Based on the current use of the Salmon Site, the following remedial actions were identified to protect both human health and the environment: (1) the installation of a water supply system that will provide potable water to the site and residence in the proximity to the site; (2) continued maintenance of surface institutional controls and subsurface restrictions; and (3) continue to implement the long-term hydrologic monitoring program. The Salmon Site will be relinquished the State of Mississippi as mandated by Public Law 104-201-September 23, 1996, to be used as a demonstration forest/wildlife refuge. Should the land use change in the future and/or monitoring information indicates a change in the site conditions, the DOE will reassess the risk impacts to human health and the environment.

Numerical Investigations of Kuiper Belt Binaries  

E-Print Network (OSTI)

Observations of the Kuiper Belt indicate that a larger than expected percentage of KBO's (approximately 8 out of 500) are in binary pairs. The formation and survival of such objects presents a conundrum [1]. Two competing theories have been postulated to try to solve this problem. One entails the physical collision of bodies [2] while the other utilizes dynamical friction or a third body to dissipate excess momentum and energy from the system [3]. Although in general known binaries tend to differ significantly in mass, such as seen in the Earth-Moon or asteroid binary systems [4], Kuiper binaries discovered to date tend to instead be of similar size [5, 6]. This paper investigates the stability, development and lifetimes for Kuiper Belt binaries by tracking their orbital dynamics and subsequent evolution. Section two details the numerical model while Section three discusses the initial conditions. Finally, in Section four the results are discussed with Section five containing the conclusions.

Investigation of flow characteristics of gas turbines  

SciTech Connect

Measurements carried out in the process of assimilation of gas turbine (GT) plants of 16 different types in starting and working conditions to estimate the operational conditions and characteristics of the main elements (in particular of the turbines) have created a basis for generaliztion of flow characteristics of different turbines and for extending them to a wider range of operational conditions. The studies showed that: flow characteristics of the investigated turbines, independently of the number of stages and the degree of reaction, are described by the elliptic flowrate equation; throughput of similar turbines, i.e., of turbines formed of stages with high reaction, which have low design degrees of expansion, can be determined with satisfactory accuracy by the unique function of the degree of expansion; and in operating the gas turbine plants considerable changes in throughput of the turbines are possible.

The POLAR Investigation of the Sun (POLARIS) mission uses a combination of a gravity assist and solar sail propulsion to place a spacecraft in a 0.48 AU circular orbit around the Sun with an inclination of 75 degrees with respect to solar equator. This challenging orbit is made possible by the challenging development of solar sail propulsion. This first extended view of the high-latitude regions of the Sun will enable crucial observations not possible from the ecliptic viewpoint or from Solar Orbiter. While Solar Orbiter would give the first glimpse of the high latitude magnetic field and flows to probe the solar dynamo, it does not have sufficient viewing of the polar regions to achieve POLARIS' primary objective : determining the relation between the magnetism and dynamics of the Sun's polar regions and the solar cycle.

Yucca Mountain, located on and adjacent to the Nevada Test Site, is being characterized as part of an ongoing effort to identify a potential high-level nuclear waste repository. This site will be subjected to seismic ground motions induced by underground nuclear explosions. A knowledge of expected ground motion levels from these tests will enable the designers to provide for the necessary structural support in the designs of the various components of the repository. The primary objective of the Weapons Test Seismic Investigation project is to develop a method to predict the ground motions expected at the repository site as a result of future weapons tests. This paper summarizes the data base presently assembled for the Yucca Mountain Project, characteristics of expected ground motions, and characterization of the two-dimensional seismic properties along paths between Yucca Mountain and the testing areas of the Nevada Test Site.

An investigation into Facebook friend grouping  

E-Print Network (OSTI)

Abstract. With increasingly large friend networks, Facebook users may be losing sight of exactly with whom they are sharing content they post to Facebook. When Facebook released a new privacy interface in summer 2010 they simplified privacy controls; however, group-based permissions remain at the core of fine-grained privacy control. In order to use these fine-grained controls, users must be able to accurately and usefully specify friend groups. In a series of 46 semi-structured interviews, we investigated how participants group their online friends using four different grouping methods. Our results show that these different mechanisms alter the strategies and groups that users create, that groups created a priori need further refinement before they can adequately address privacy decisions, and that users are adapting their online behavior to avoid the need to specify groups in the current Facebook interface. We conclude with several recommendations that would allow users improved group-based access control.

Investigations into coal coprocessing and coal liquefaction  

DOE Green Energy (OSTI)

The conversion of coal to liquid suitable as feedstock to a petroleum refinery is dependent upon several process variables. These variables include temperature, pressure, coal rank, catalyst type, nature of the feed to the reactor, type of process, etc. Western Research Institute (WRI) has initiated a research program in the area of coal liquefaction to address the impact of some of these variables upon the yield and quality of the coal-derived liquid. The principal goal of this research is to improve the efficiency of the coal liquefaction process. Two different approaches are currently being investigated. These include the coprocessing of a heavy liquid, such as crude oil, and coal using a dispersed catalyst and the direct liquefaction of coal using a supported catalyst. Another important consideration in coal liquefaction is the utilization of hydrogen, including both externally- and internally-supplied hydrogen. Because the incorporation of externally-supplied hydrogen during conversion of this very aromatic fossil fuel to, for example, transportation fuels is very expensive, improved utilization of internally-supplied hydrogen can lead to reducing processing costs. The objectives of this investigation, which is Task 3.3.4, Coal Coprocessing, of the 1991--1992 Annual Research Plan, are: (1) to evaluate coal/oil pretreatment conditions that are expected to improve the liquid yield through more efficient dispersion of an oil-soluble, iron-based catalyst, (2) to characterize the coke deposits on novel, supported catalysts after coal liquefaction experiments and to correlate the carbon skeletal structure parameters of the coke deposit with catalyst performance as measured by coal liquefaction product yield, and (3) to determine the modes of hydrogen utilization during coal liquefaction and coprocessing. Experimental results are discussed in this report.

Wood Pulp Digetster Wall Corrosion Investigation  

DOE Green Energy (OSTI)

The modeling of the flow in a wood pulp digester is but one component of the investigation of the corrosion of digesters. This report describes the development of a Near-Wall-Model (NWM) that is intended to couple with a CFD model that determines the flow, heat, and chemical species transport and reaction within the bulk flow of a digester. Lubrication theory approximations were chosen from which to develop a model that could determine the flow conditions within a thin layer near the vessel wall using information from the interior conditions provided by a CFD calculation of the complete digester. The other conditions will be determined by coupled solutions of the wood chip, heat, and chemical species transport and chemical reactions. The NWM was to couple with a digester performance code in an iterative fashion to provide more detailed information about the conditions within the NW region. Process Simulations, Ltd (PSL) is developing the digester performance code. This more detailed (and perhaps more accurate) information from the NWM was to provide an estimate of the conditions that could aggravate the corrosion at the wall. It is intended that this combined tool (NWM-PSL) could be used to understand conditions at/near the wall in order to develop methods to reduce the corrosion. However, development and testing of the NWM flow model took longer than anticipated and the other developments (energy and species transport, chemical reactions and linking with the PSL code) were not completed. The development and testing of the NWM are described in this report. In addition, the investigation of the potential effects of a clear layer (layer reduced in concentration of wood chips) near the wall is reported in Appendix D. The existence of a clear layer was found to enhance the flow near the wall.

A rhetorical investigation of Triumph of the Will  

E-Print Network (OSTI)

In 1935 Triumph of the Will--Riefenstahl's film of the 1934 National Socialist Party rally in Nuremberg--made its debut before an audience composed of Hitler, Goebbels and other high-ranking members of the Nazi Party. The film was personally commissioned by Hitler, and since its release has been the target of criticism as a blatant work of pro-Nazi propaganda. This thesis examines Triumph of the Will as a rhetorical artifact. Leni Riefenstal drew upon elements of contemporary cinema, utilized deeply rooted cultural symbols and references, and combined them with supreme skill to construct a work of art that was not only an effective source of propaganda in the nineteen-thirties, but continues to influence modem media today.

Investigating isomorphs with the topological cluster classification  

E-Print Network (OSTI)

Isomorphs are lines in the density-temperature plane of certain "strongly-correlating" or "Roskilde simple" liquids where two-point structure and dynamics have been shown to be close to identical up to a scale transformation. Here we consider such a liquid, a Lennard-Jones glassformer, and investigate the behavior along isomorphs of higher-order structural and dynamical correlations. We then consider an inverse power law reference system mapped to the Lennard-Jones system [Pedersen et al., Phys. Rev. Lett. 105, 157801 (2010)]. Using the topological cluster classification to identify higher-order structures, in both systems we find bicapped square anti-prisms, which are known to be a locally favored structure in the Lennard-Jones glassformer. The population of these locally favored structures is up to 80% higher in the Lennard-Jones system than the equivalent inverse power law system. The structural relaxation time of the two systems, on the other hand, is almost identical, and the four-point dynamical susceptibility is marginally higher in the inverse power law system. Upon cooling the lifetime of the locally favored structures in the Lennard-Jones system are up to 40% higher relative to the reference system.

Investigating Dark Energy with Black Hole Binaries  

E-Print Network (OSTI)

The accelerated expansion of the universe is ascribed to the existence of dark energy. Black holes accretion of dark energy induces a mass change proportional to the energy density and pressure of the background dark energy fluid. The time scale during which the mass of black holes changes considerably is too long relative to the age of the universe, thus beyond detection possibilities. We propose to take advantage of the modified black hole masses for exploring the equation of state $w[z]$ of dark energy, by investigating the evolution of supermassive black hole binaries on a dark energy background. Deriving the signatures of dark energy accretion on the evolution of binaries, we find that dark energy imprints on the emitted gravitational radiation and on the changes in the orbital radius of the binary can be within detection limits for certain supermassive black hole binaries. In this talk I describe how binaries can provide a useful tool in obtaining complementary information on the nature of dark energy, based on the work done with A.Kelleher.

Investigation of global Alfven instabilities in TFTR  

Science Conference Proceedings (OSTI)

Toroidal Alfven Eigenmodes (TAE) were excited by the energetic neutral beam ions tangentially injected into TFTR plasmas at low magnetic field such that the injection velocities were comparable to the Alfven speed. The modes were identified by measurements from Mirnov coils and beam emission spectroscopy (BES). TAE modes appear in bursts whose repetition rate increases with beam power. The neutron emission rate exhibits sawtooth-like behavior and the crashes always coincide with TAE bursts. This indicates ejection of fast ions from the plasma until these modes are stabilized. The dynamics of growth and stabilization was investigated at various plasma current and magnetic field. The results indicate that the instability can effectively clamp the number of energetic ions in the plasma. The observed instability threshold is discussed in the light of recent theories. In addition to these TAE modes, intermittent oscillations at three times the fundamental TAE frequency were observed by Mirnov coils, but no corresponding signal was found in BES. It appears that these high frequency oscillations do not have direct effect on the plasma neutron source strength.

Reinvestigation on the state-of-the-art nonaqueous carbonate electrolytes for 5 V Li-ion battery applications  

SciTech Connect

The charging voltage limits of mixed carbonate solvents for Li-ion batteries have been systematically investigated from 4.9 to 5.3 V in half cells using Cr-doped spinel cathode material LiNi0.45Cr0.05Mn1.5O4. We found that the stability of conventional carbonate electrolytes is strongly related to the stability and properties of the cathode materials at both lithiated and de-lithiated states. It is the first time to report that the conventional electrolytes based on mixtures of ethylene carbonate (EC) and linear carbonate (dimethyl carbonate - DMC, ethyl methyl carbonate - EMC, and diethyl carbonate - DEC) have shown very similar long-term cycling performance when cycled up to 5.2 V on LiNi0.45Cr0.05Mn1.5O4. The discharge capacity increases with the charge cutoff voltage and reaches the highest discharge capacity at 5.2 V. The capacity retention is about 87% after 500 cycles at 1C rate for all three carbonate mixtures when cycled between 3.0 V and 5.2V. The first-cycle efficiency has a maximum value at 5.1 V, with an average from 83% to 85% at C/10 rate. When cycled to 5.3 V, EC-DMC still shows good cycling performance but EC-EMC and EC-DEC show faster capacity fading. EC-DMC and EC-EMC have much better rate capability than EC-DEC. In addition, the first-cycle irreversible capacity loss increases with the cutoff voltage and the 'inactive' conductive carbon has also been found to be partly associated with the low first-cycle Coulombic efficiency at high voltages due to electrolyte decomposition and probably the PF6- anion irreversible intercalation.

Investigation of coal structure. Final report  

SciTech Connect

A better understanding of coal structure is the first step toward more effective utilization of the most abundant hydrocarbon resource. Detailed characterization of coal structure is very difficult, even with today`s highly developed analytical techniques. This is primarily due to the amorphous nature of these high-molecular-weight mixtures. Coal has a polymeric character and has been popularly represented as a three-dimensional cross-linked network. There is, however, little or no information which positively verifies this model. The principal objective of this research was to further investigate the physical structure of coal and to determine the extent to which coal molecules may be covalently cross-linked and/or physically associated. Two common characterization methods, swellability and extractability, were used. A technique modifying the conventional swelling procedure was established to better determine network or associated model conformation. A new method for evaluating coal swelling involving laser scattering has also been developed. The charge-transfer interaction is relatively strong in high-volatile bituminous coal. Soaking in the presence of electron donors and acceptors proved effective for solubilizing the coal, but temperatures in excess of 200 C were required. More than 70 wt% of the coal was readily extracted with pyridine after soaking. Associative/dissociative equilibria of coal molecules were observed during soaking. From these results, the associated model has gained credibility over the network model as the representative structure of coal. Significant portions of coal molecules are unquestionably physically associated, but the overall extent is not known at this time.

State-of-the-art study of resource characterization and planning for underground coal mining. Final technical report as of June 30, 1980  

SciTech Connect

With the rapid developments taking place in coal mining technology and due to high investment costs, optimization of the structure of underground coal mines is crucial to the success of the mining project. The structure of a mine, once it is developed, cannot be readily changed and has a decisive influence on the productivity, safety, economics, and production capacity of the mine. The Department of Energy desires to ensure that the resource characterization and planning activity for underground coal mining will focus on those areas that offer the most promise of being advanced. Thus, this project was undertaken by Management Engineers Incorporated to determine the status in all aspects of the resource characterization and planning activities for underground coal mining as presently performed in the industry. The study team conducted a comprehensive computerized literature search and reviewed the results. From this a selection of the particularly relevant sources were annotated and a reference list was prepared, catalogued by resource characterization and mine planning activity. From this data, and discussions with industry representatives, academia, and research groups, private and federal, an assessment and evaluation was made of the state-of-the-art of each element in the resource characterization and mine planning process. The results of this analysis lead to the identifcation of areas requiring research and, specifically, those areas where DOE research efforts may be focused.

Metropolitan Washington Council of Governments National Capital Region Transportation Planning Board Summary of the State of the Practice and State of the Art of Modeling Peak Spreading  

E-Print Network (OSTI)

Traffic congestion in large metropolitan areas has become so acute that many commuters are adjusting their departure and/or arrival times for work and other destinations to avoid the worst of what is now called the “peak period”. The adjustments in departure times combined with travel times that can last beyond the peak hour have led to the phenomena of peak spreading, where the peak hour demand on a particular roadway exceeds the peak hour capacity and causes demand to shift to the “shoulders ” of the peak hour, or the hours adjacent to the peak hour. This situation is so pronounced in the TPB region, that most of the major freeways in the areas have peak periods that last from roughly 6 AM to 10 AM in the morning and 3 PM to 7 PM in the evening where stop and go traffic is common throughout. The Metropolitan Washington Council of Governments, National Capital Region Transportation Planning Board (TPB) engaged Vanasse Hangen Brustlin (VHB) to review and summarize the state of the practice and the state of the art with regards to modeling peak spreading at the MPO level. VHB began this effort by reviewing the recent MPO survey and following up with staff at large MPOs with characteristics similar

Review of state-of-the-art of solar collector corrosion processes. Task 1 of solar collector studies for solar heating and cooling applications. Final technical progress report  

DOE Green Energy (OSTI)

The state-of-the-art of solar collector corrosion processes is reviewed, and Task 1 of a current research program on use of aqueous heat transfer fluids for solar heating and cooling is summarized. The review of available published literature has indicated that lack of quantitative information exists relative to collector corrosion at the present time, particularly for the higher temperature applications of solar heating and cooling compared to domestic water heating. Solar collector systems are reviewed from the corrosion/service life viewpoint, with emphasis on various applications, collector design, heat transfer fluids, and freeze protection methods. Available information (mostly qualitative) on collector corrosion technology is reviewed to indicate potential corrosion problem areas and corrosion prevention practices. Sources of limited quantitative data that are reviewed are current solar applications, research programs on collector corrosion, and pertinent experience in related applications of automotive cooling and non-solar heating and cooling. A data bank was developed to catalog corrosion information. Appendix A of this report is a bibliography of the data bank, with abstracts reproduced from presently available literature accessions (about 220). This report is presented as a descriptive summary of information that is contained in the data bank.

PRISE: petroleum resource investigation summary and evaluation  

E-Print Network (OSTI)

As conventional resources are depleted, unconventional gas (UG: gas from tight sands, coal beds, and shale) resources are becoming increasingly important to U.S and world energy supply. The volume of UG resources is generally unknown in most international basins. However, in 25 mature U.S. basins, UG resources have been produced for decades and are well characterized in the petroleum literature. The objective of this work was to develop a method for estimating recoverable UG resources in target, or exploratory, basins. The method was based on quantitative relations between known conventional and unconventional hydrocarbon resource types in mature U.S. basins. To develop the methodology to estimate resource volumes, we used data from the U.S. Geological Survey, Potential Gas Committee, Energy Information Administration, National Petroleum Council, and Gas Technology Institute to evaluate relations among hydrocarbon resource types in the Appalachian, Black Warrior, Greater Green River, Illinois, San Juan, Uinta-Piceance, and Wind River basins. We chose these seven basins because they are mature basins for both conventional and unconventional oil and gas production. We assumed that a seven basin study would be sufficient for preliminary gas resource analysis and assessment of the new methodology. We developed a methodology we call PRISE, which uses software that investigates relationships among data published for both conventional and unconventional resources in the seven mature U.S. basins. PRISE was used to predict recoverable UG resources for target basins, on the basis of their known conventional resources. Input data for PRISE were cumulative production, proved reserves, growth, and undiscovered resources. We used published data to compare cumulative technically recoverable resources for each basin. For the seven basins studied, we found that 10% of the recoverable hydrocarbon resources are conventional oil and gas, and 90% are from unconventional resources. PRISE may be used to estimate the volume of hydrocarbon resources in any basin worldwide and, hopefully, assist early economic and development planning. PRISE methodology for estimating UG resources should be further tested in diverse sedimentary basin types.
