In response to this U.S. Department of Energy Phase I Energy Conservation Applications for Solid- State Lighting (OLEDs) SBIR, InnoSys and Universal Display Corporation (UDC) propose to develop and commercialize drivers and power supplies specifically designed for high efficiency phosphorescent organic light emitting diodes (PHOLEDs) lighting panels, for a variety of indoor and outdoor lighting ap ...

High Performance Computing has enabled computer modeling of everlarger and more complex problems. For some of these problems, models utilizing allhexahedral meshes are preferred due to better accuracy and efficiency. However, algorithms for automatic generation of all hex meshes in general geometries have so far eluded researchers. Currently, these meshes are typically created by subdividing the o ...

The development of large-area (m2) photodetectors with time resolutions of picoseconds (10-12 seconds) and submillimeter space resolutions would open new opportunities in many areas, including collider detectors, rare kaon experiments, and neutrino experiments in particle and nuclear physics, X-ray detection at light sources, and Time-Of -Flight Positron Emission Tomography (TOF-PET). This propo ...

The objective of this project is to design and build a high-efficiency neutron detector array consisting of 3000 pixels, with each pixel being 100 microns wide and 4 cm tall, all based on the microstructured semiconductor neutron detector (MSND) technology. The MSND technology resulted in over 40 publications, three allowed patents, one patent pending, and recently received an R & amp;D 100 award ...

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 ...

Existing building stock represents a significant opportunity for energy savings through efficiency measures, as it accounts for 41% of US energy use. Advanced control strategies and better systems commissioning offer the least expensive routes to energy savings by utilizing existing building infrastructure with only minimal additional investment cost. If a conservative estimate of 25% energy savin ...

Wetzel Engineering, Inc., proposes research and development to engineer very large wind turbine rotor blades for land-based machines that avoid expensive and logistically challenging transportation requirements. The proposed solution combines two technologies: Sectional component-based assembly of large wind turbine rotor blades ( & gt;65m length) using design approaches adapted from aerospace co ...

Critical to determining the success of an EGS well is the measurement of the flow distribution along the open-hole length of that well. Knowledge of not only the depth but the spacing of intersected fractures is required in order to determine the sweep efficiency of fluids flowing through the reservoir. Currently, the only device available for measuring fluid flow within a geothermal wellbore is t ...

ABSTRACT: Ground Surveillance Radar (GSR) is a fundamental and proven component of Department of Defenses (DoD) Battlefield Awareness. Advanced radar systems on large remotely piloted aircraft (RPAs) include Synthetic Aperture Radar (SAR) and Ground Moving Target Indicators (GMTI). The ability to identify and track vehicles and dismounts has become a key focus. Small (< 10 lb) radars with SAR i ...
