As organizations move toward increased performance measurement and accountability, there is an increasing need to measure job performance at the individual worker level. Traditional assessment tools have been criticized as measuring test taking skills more than job performance skills. A number of approaches have been developed to address this weakness by measuring performance in practical proble ...

1. A conceptual baseline design of a hydrogen supply system with a on/off capability will be prepared for delivering hydrogen in increments of up to 10g/hour with a total capacity of 120g hydrogen. This baseline design will be based upon a solid state hydrogen reactant mixture with a yield of 8% by reactant weight which has been previously qualified for military use. ...

Silicon carbide materials will revolutionize semiconductor devices for military and commercial markets. The material's wide bandgap, high electric field breakdown, high thermal conductivity give SiC capabilities that far exceed those of silicon or gallium arsenide. Despite significant progress in silicon carbide development, fundamental defects--most prominently micropipes--persist. If SiC is to s ...

The properties of single-crystal silicon carbide are such that electronics devices from this material have demonstrated remarkable performance characteristics. Despite the material's promise, the material has not yet found acceptance in mainstream device markets because of the material's high cost, among other reasons. This Phase I SBIR proposes an SiC source powder with unique properties which wi ...

Frog Embryo Teratogenesis Assay: Xenopus (FETAX) is a 96-h, whole-embryo bioassay designed to detect potential developmental toxicants. The primary goal of this research is to improve the predictability and increase the overall utility of FETAX as a screen for developmental toxicants that pose a hazard to human health. Since Xenopus laevis embryos lack mixed-fliriction oxidase metabolism (cytoch ...

To field characterize laser systems the laser power, beam divergence, intensity profile and spot size of the laser must be measured with a robust, vibration insensitive system. While some of these parameters can be obtained using conventional components, beam divergence is difficult to measure because of the complexity and vibration sensitivity of typical interferometry based elements. We propos ...

We propose here to evaluate a variety of inorganic scintillators, including sodium iodide and bismuth germanate, for use in energy-sensitive neutron detectors. We will couple these crystals to photomultiplier tubes and measure the prompt response to inelastic neutron reactions with the scintillator atoms. To unfold the incident neutron energy distribution from the resulting signal pulse heights, ...
