DESCRIPTION (provided by applicant): The Health and Retirement Study is one of the world's most important data resources for the study of aging. The basic longitudinal survey instrument has been supplemented with data from a variety of other sources including Social Security Administration records containing the detailed earnings history of the respondent. Under current HRS protocols, the use of t ...

Many military missions involve the use of equipment that requires small batteries for power where AC grid power is unavailable. Also, there is a need for a high quality power output device that conditions a power input to make it suitable to power sensitive communications equipment. The weight of this equipment is also a factor which affects Its usefullness in quick moving military situations. M ...

Light weight, low cost structures is the direction that many aerospace companies are working toward. Our objective in this Phase I program is to demonstrate our low cost effective manufacturing methods with thermoplastic composites while maintaining structural integrity. A continuous graphite fiber reinforced thermoplastic prepreg tape will be used in conjunction with our automated in-situ fiber ...

This proposal addresses the application of new acoustic processing technologies to automatically identify and eliminate non-language speech sounds as a pre-processing stage to improve audio processing. Non-language speech sounds make up a large part of natural human language use, but contemporary speech recognition data preparation relies on hand-labeling of non-language speech sounds. The propose ...

The Jaws-Of-Life is a hydraulic rescue tool used to rip cars apart. They consist of a pair of metal claws that are used to spread/cut/rip automobiles or other metal constructions apart in order to save persons who may be trapped inside. The Jaws of Life were originally designed for race track use but have since become a tool of rescue crews everywhere. Hale Products presently own the trademark Jaw ...

High-repetition-rate (>1 MHz), high-bunch-charge (up to 1 nC) electron sources, possessing the high gradients at the cathode surface that are needed for low emittance electron bunches, are critical components of next generation light sources, such as energy recovery linacs (ERLs) and free electron lasers (FELs), and are essential for other advanced accelerator applications. The high-brightness in ...

Modern turbine engines undergo extensive ground testing in test cells during development. These engines are instrumented with numerous strain gages for high-frequency dynamic strain measurements. Currently, analog signals from these gages are routed out of the test cell to remote data acquisition equipment over hundreds of feet of wire. With up to 200 gages to be installed, the task of patching ...

Political, economic, and environmental considerations require that the national dependence on petroleum-based transportation fuels, especially imported oil, be reduced by accelerating the development of domestic renewable alternatives. The United States has the potential to generate, sustainably, about 1.3 billion dry tons of biomass per year, and bio-oil derived from this renewable feedstock cou ...

The release of volatile organic compounds from industrial processes can have negative impacts on the environment while also posing significant health and safety concerns. In the environment, many of these chemical are considered precursors to ground-level ozone, which is the primary component of smog. In addition, many volatile organic compounds are cancer-causing in humans while others pose dan ...
