The U.S. DOE Office of Environmental Management (EM) was created in 1989 to manage the cleanup of large areas of environmentally contaminated sites. Since the closure of many of these sites, U.S. taxpayers have spent about $220 billion at 74 cleanup sites. However, these sites were the smallest and most manageable sites to clean. There are still over 40 sites that are deemed as eno ...

Many contaminated DOE sites are located in arid regions where depth to groundwater is significant and/or contaminants were discharged into a vadose zone through which transport to the groundwater table is dominated by unsteady, unsaturated groundwater flow. The absence of an effective means to monitor vadose zone moisture content in profile has been a persistent impediment to developing and calibr ...

Increased use of Exhaust Gas Recirculation (EGR) combined with engine downsizing has pushed automotive turbocharger compressor operation towards and often beyond its efficient and stable operating boundaries. Much of the drive cycle is spent operating the compressor at low flow rates and low pressure ratios, near the compressor surge line, in an area which is usually of low efficiency. Our prelimi ...

There is a Global Safeguards need for tamper-indicating coatings of varying complexity for use in the verification and authentication of nuclear security documents, materials, and equipment; however, current commercial coatings for anti-tampering seals lack the sophistication necessary for quick, accurate, and reliable tamper detection. Tetramer has developed a proprietary family of coating techno ...

ABSTRACT: We propose to develop novel high-temperature robust control ICs compatible with power SiC device using on insulated gate III-Nitride transistors MISHFETs - over SiC native nitride substrate. SET Inc patented GaN MISHFET technology offers radical device performance improvement over SiC MOSFETs and other device types in terms of transconductance and speed of response, due to an extremely ...

ABSTRACT: Flow Modeling and Simulation, LLC (FMS), proposes to develop a computational software tool, herein designated AUG3D, that is intended to provide physics-based, multi-level, validated computational simulations of turbine engine component flow fields, particularly those associated with thrust augmentors, i.e., afterburners. This tool will be ideally suited for closely integrating physica ...

ABSTRACT: The SCRAMSIM computer code will be able to perform analysis for engineering design, stemming from a low order Reynolds Average Navier-Stokes (RANS) to high order (4th or higher) LES using accurate subgrid scale models (SGS). It will also solve thermal non-equilibrium mechanisms, conjugated heat transfer, general finite-rate chemistry using several databases for hydrocarbon/hydrogen-air ...

Appareo Systems, LLC, proposes to develop a functional prototype head-mounted position and orientation system (HPOS). The HPOS will be capable of operating in electromagnetic fields of up to 200 volts/meter and will provide at least one degree of accuracy and at least one degree of resolution at a 60 Hz update rate while providing 3 degree of freedom (DOF) information on head orientation, includi ...

The goal of this SBIR project will be to use composite materials with a unique combination of low dielectric constant and loss, high bending modulus, and high tensile strength to make tri band radomes for airborne antennas with superior transmission loss and insertion angle.

Energy usage will continue to increase at a dramatic pace for the foreseeable future, endangering the security, economy, and environment of the nation. One means of meeting this challenge is the replacement of liquid transportation fuels based on petroleum with cellulosic bioethanol. However, cellulosic ethanol remains too costly to be commercially feasible, in part due to the generation of orga ...
