Fabrication of stable, nearly 100% internal carrier collection efficiency silicon photodiodes (AXUV diodes) for 1 nm to 600 nm photons was successfully demonstrated by us several years ago. Owing to their excellent characteristics, these devices are being used by NIST as transfer standards in 5 nm to 250 nm range and aboard SOHO, SNOE and TIMED instruments for the EUV solar spectrum studies. Alt ...

An innovative optical system with 500X higher ¿tendu and spatial resolution will be designed for CCD-based bistatic lidar. A 100¿ vertical field of view is required to image the laser beam from the ground through the boundary layer, but only a few degrees are required in the horizontal direction. The proposed design is based on dividing the vertical field of view into N sectors, using 1D rasteri ...

An automated, high precision, lightweight gas chromatograph, capable of measuring hydrogen (H2), methane (CH4), carbon monoxide (CO) and carbon dioxide (CO2) with a fast duty cycle (1 sample per two minutes) will be designed and built. The detector used for the chromatograph will be an electron capture detector with sensitivity enhanced by addition of nitrous oxide (N2O) reagent gas. The instrum ...

A need exists for economical, high capacity softwre to aid medical and engineering researchers to more easily and consistently calculate forces acting on vehicle occupants during real-world crashes. One example of such research is NHTSA's Crash Injury research and Engineering Network (CIREN), which in adition to collecting injury and vehicle information, has increasing access to data from Event D ...

Spray drift is one of the most significant issues presently facing agricultural applicators. Agricultural applicators are committed to the management of chemical drift and take responsibility on a daily basis for making good decisions in the field. Material that drifts off-site is material that is not applied to the target crop or pest and represents both wasted time and wasted material. This equa ...

Hybrid striped bass (HSB) aquaculture has become the fourth largest form of U.S. finfish production, trailing only catfish, trout, and salmon in market value. To compete effectively with low-cost foreign imports, U.S. HSB producers need to develop advanced strains that grow more rapidly and convert feed more efficiently. However, HSB are produced from two parental species (white bass and striped b ...

Although Near Infrared Spectroscopy (NIRs) is a powerful non-invasive technique for identifying constituent components in a variety of agricultural products, current NIRs instrumentation is bulky and expensive, and requires long measurement times. This limits the use of NIRs in remote settings and high-speed sorting applications. This project seeks to apply miniaturized semiconductor laser technol ...

The nutritional paradox in this nation is that although food is abundant, most Americans eat poorly. The American diet is characterized by high intake of fat and saturated fat, and low intake of calcium, whole grains, fruits, vegetables and fiber. The USDA¿s Healthy Eating Index gauges the adequacy of the American diet. The most recent Index reveals that only 10% of the U.S. population has a go ...

ROCKMAN ET AL and WestEd propose to research a promising school improvement tool designed to assist schools with implementing improvement processes. As evidenced in the Phase I feasibility study, the School Improvement Implementation and Monitoring Tool (SIIMT) has been shown to provide valuable help in a variety of settings. In a two-year Phase II research study, we propose to refine and add feat ...

Further refinement of a Phase I developed prototype tilt-in-space wheelchair called the PALM specifically designed to meet pediatric needs; verification of functionality with end-user testing and evaluation will also be conducted
