U.S. Postal Service: Moving Forward on Financial and Transformation Challenges

Description: Testimony issued by the General Accounting Office with an abstract that begins "The U.S. Postal Service continues to face financial and transformation challenges. Since GAO placed the Service's long-term outlook and transformation efforts on its high-risk list, the Service's financial situation has continued to decline, and its operational challenges have increased. The Service took a good first step when it issued its Transformation Plan. The plan provides information about the Service's chall… more

Dynamic information architecture system (DIAS) : multiple model simulation management.

Description: Dynamic Information Architecture System (DIAS) is a flexible, extensible, object-based framework for developing and maintaining complex multidisciplinary simulations of a wide variety of application contexts. The modeling domain of a specific DIAS-based simulation is determined by (1) software Entity (domain-specific) objects that represent the real-world entities that comprise the problem space (atmosphere, watershed, human), and (2) simulation models and other data processing applications tha… more

Source Release Modeling for the Idaho National Engineering and Environmental Laboratory's Subsurface Disposal Area

Description: A source release model was developed to determine the release of contaminants into the shallow subsurface, as part of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) evaluation at the Idaho National Engineering and Environmental Laboratory's (INEEL) Subsurface Disposal Area (SDA). The output of the source release model is used as input to the subsurface transport and biotic uptake models. The model allowed separating the waste into areas that match the actual … more

MONITORING POWER PLANT EFFICIENCY USING THE MICROWAVE-EXCITED PHOTOACOUSTIC EFFECT TO MEASURE UNBURNED CARBON

Description: Three test instruments are being evaluated to determine the feasibility of using photo-acoustic technology for measuring unburned carbon in fly ash. The first test instrument is a single microwave frequency system previously constructed to measure photo-acoustic signals in an off-line configuration. This system was assembled and used to begin testing parameters thought to be influential in the resulting photo-acoustic signal output. A standard modulation frequency was chosen based upon signal t… more

Defect Structure and Evolution in Silicon Carbide Irradiated to 1 dpa-SiC at 1100 C

Description: Transmission electron microscopy (TEM), swelling measurements, isochronal annealing, and thermal diffusivity testing were used to characterize the effects of radiation damage in SiC. Together, these techniques provided a comprehensive set of tools for observing and characterizing the structure and evolution of radiation-induced defects in SiC as a function of irradiation temperature and dose. In this study, two types of dense, crystalline, monolithic SiC were subjected to irradiation doses up t… more

Greybull Sandstone Petroleum Potential on the Crow Indian Reservation, South-Central Montana

Description: The focus of this project was to explore for stratigraphic traps that may be present in valley-fill sandstone at the top of the Lower Cretaceous Kootenai Formation. This sandstone interval, generally known as the Greybull Sandstone, has been identified along the western edge of the reservation and is a known oil and gas reservoir in the surrounding region. The Greybull Sandstone was chosen as the focus of this research because it is an excellent, well-documented, productive reservoir in adjacen… more

Residual stress measurement in YBCO thin films.

Description: Residual stress in YBCO films on Ag and Hastelloy C substrates was determined by using 3-D optical interferometry and laser scanning to measure the change in curvature radius before and after film deposition. The residual stress was obtained by appropriate analysis of curvature measurements. Consistent with residual thermal stress calculations based on the thermal expansion coefficient mismatch between the substrates and YBCO film, the measured residual stress in the YBCO film on Hastelloy C su… more

Using Decision Analysis in Evaluation and Prioritization of Technologies for Long Term Stewardship

Description: The purpose of this paper is to describe a systematic approach to assess and prioritize technology concepts and systems for future research and development (R and D) funding. This paper discusses the analysis and rationale used in developing an evaluation process to assist those engaged in prioritizing technologies. This paper will explain the developed evaluation process, discuss the methodology, and summarize the rationale underlying the process.

Effects of an External Perturbation on a Cylindrical Spheromak

Description: In experiments like the spheromak, it becomes interesting to investigate the quality o f the magnetic flux surfaces in the device. One method of doing so is to impose an external perturbation. If the magnetic field without perturbation is tangled and no flux surfaces exist, then the perturbation will have little effect. However, if the field has well defined flux surfaces, the field should react strongly to a perturbation. Magnetic islands should form and potentially cause a degradation of the … more

RESONANT X-RAY SCATTERING AS A PROBE OF ORBITAL AND CHARGE ORDERING.

Description: Resonant x-ray scattering is a powerful experimental technique for probing orbital and charge ordering. It involves tuning the incident photon energy to an absorption edge of the relevant ion and observing scattering at previously ''forbidden'' Bragg peaks, and it allows high-resolution, quantitative studies of orbital and charge order--even from small samples. Further, resonant x-ray scattering from orbitally ordered systems exhibits polarization- and azimuthal-dependent properties that provid… more
