Foods are dehydrated to make them more easily packaged and stored at room temperature. The removal of water reduces the opportunity for harmful chemical reactions. Dehydrated food powders and particles are also used in "liquid meals" for dental patients. However, dehydrated foods traditionally have been difficult to rehydrate and are of relatively poor quality. The reasons for these difficulties a ...

Fuel cells are being considered by the Army for future individual soldier power supplies. These power units are to be lightweight, compact and suitable for use on the battlefield. A compact, lightweight, safe source of pure hydrogen (and possibly oxygen) is urgently needed. The proposed report will examine a series of high pressure hydrogen and liquid hydrogen storage systems suitable for an indiv ...

SAG Corporation proposes to develop a framework for measuring the economic and social costs and benefits of an Army career. The research will focus on identifying and evaluating data sources and developing quantitative methods and procedures for comparing these costs and benefits. The resulting model will go beyond traditional retention models to look at the total impact of an Army career on an in ...

Adroit Systems, Inc. proposes to develop a hand-held , autonomous Satellite Location and Point System (SLAPS). The system will store communication satellites' ephemeris data to calculate and display visibility windows. SLAPS also will use this data to calculate the azimuth and elevation angle to the communication satellite of interest. The system will use interferometry of Global Positioning Syste ...

Advanced turbine engines and flight vehicles will depend upon new, high-temperature metal matrix composites (MMC's) to meet performance goals. Engineering characterization of such materials is difficult and costly, which accounts for the meager property database available to designers. Thin-walled tubes would be especially useful for developing constitutive relations and failure criteria under mul ...

A major obstacle to the establishment and measurement of valid cause and effect relationships between Army service and the costs and benefits of such service is the impossibility of performing experiments with random assignment of individuals to service and non-service groups. A recent innovation in statistical theory, propensity score methodology, allows one to draw from an observational (or retr ...
