WE PROPOSE AN EFFICIENT AND COST-EFFECTIVE QUERY PROCESSING COMPONENT FOR AN INFORMATION RETRIEVAL SYSTEM BASED ON THE USE OF NETWORKED MICROCOMPUTERS AS A LOOSELY-COUPLED NETWORK DATABASE. THE QUERY PROCESSSING SYSTEM WILL WORK ON BOTH LOCAL AND WIDE AREA NETWORKS AND CAN BE USED WITH ANY METHOD OF INFORMATION RETRIEVAL. WE PROPOSE TO: 1. MODEL THE EXPECTED PERFORMANCE OF THIS SYSTEM SO THAT IT M ...

The use of cryogenic solid hydrogen as a rocket propellant may lead to major advances in rocket propulsion. To use solid hydrogen as a propellant requires a system designed to solidfy, store, and transport hydrogen. We propose to study different methods for creating H2 for more than one hour at temperature less than 10 K. Alternative methods of delivering the solid hydrogen to the combustion chamb ...

THE INCREASING SPEED AND COMPLEXITY OF MODERN (AND FUTURE) AIR-VEHICLE SYSTEMS ARE PUSHING THE HUMAN OPERATOR TO HIS LIMITS, ESPECIALLY IN COGNITIVE-RELATED TASKS. IT IS THEREFORE OF PARTICULAR IMPORTANCE TO DEVELOP TECHNIQUES THAT ALLOW THE COMPUTER TO HELP THE HUMAN TO EXTEND THESE LIMITS. AN IMPORTANT CLASS OF SUCH ENABLING TECHNOLOGIES IS AN ACTIVE, MIXED-INITIATIVE MAN-MACHINE INTERFACE (MMI) ...

CHI Systems Inc, proposes to study the E-2C mission and to determine the conditions under which its traditional 4-5 hour duration can be extended without additional detrimental effects on aircrew performance. In Phase I we will (1) identify and assess key factors in E-2C fatigue via knowledge acquisition from current aircraft domain experts using interview, survey, and literature search, (2) make ...

CHI Systems proposes to develop and exercise a methodology that will enable pilot anthropometry and eye positioning data to be used to optimize the selection and placement of electronic displays in the E-2C cockpit. In Phase I we will (1) define electronic information display options and human factors issues that impact display selection and placement, (2) identify E-2C critical pilot tasks that i ...

DHWA PROPOSES TO DEVELOP ALGORITHMS FOR LONG-RANGE, PASSIVE TARGET MOTION ANALYSIS (TMA). THE ALGORITHMS WILL USE EXTENDED FILTERS SIMILAR TO THOSE FOUND IN CURRENT ALGORITHMS (JASA, MPKAST, AND MTST), BUT WILL UNIFY AND EXTEND THESE TECHNIQUES IN IMPORTANT WAYS. WE HOPE TO ELIMINATE MOST OF THE PROBLEMS ASSOCIATED WITH CURRENT METHODS. THE DIFFERENCES AMONG CURRENT ALGORITHMS, AND THEIR LIMITATIO ...
