TO SUPPORT THE DEVELOPMENT OF TANK DEFENSE SYSTEMS, MULTI-BEAM PHASED ARRAY SENSORS FOR THE DETECTION AND TRACKING OF HOSTILE PROJECTILES ARE BEING ANALYZED. AN ENVIRONMENT WHERE SUCH SENSORS MAY BE TESTED AT LOW-COST IS DESIRED. SUCH AN ENVIRONMENT CAN BE PROVIDED THROUGH THE USE OF MODELING AND SIMULATION, COMBINED WITH THE DEMONSTRATION OF A HARDWARE PROTOTYPE. FOR THIS PHASE I TASK, A SIMULATI ...

A HIGH-EFFICIENCY ATMOSPHERIC MOISTURE COLLECTION SYSTEM (AMCS) IS PROPOSED THAT USES A LIQUID DESICCANT TO EXTRACT WATER VAPOR FROM THE AIR. A STREAM OF POTABLE WATER IS RECOVERED FROM THE DESICCANT IN A SIMPLE BOILER. THE EFFICIENCY OF THE AMCS IS GREATLY IMPROVED BY USING AN ENGINE-DRIVEN COMPRESSOR TO RAISE THE PRESSURE OF THE STEAM FROM THE BOILER TO A LEVEL AT WHICH THE HEAT OF CONDENSATION ...

AIRCRAFT MAINTENANCE PRACTICES USE A NUMBER OF HAZARDOUS MATERIALS. HAZARDOUS MATERIALS MANAGEMENT PRACTICES CONSIST OF A RANGE OF ALTERNATIVES INCLUDING THE INSTITUTION OF NEW PROCESS, MODIFICATION OF EXISTING PROCESSES, AND MATERIALS SUBSTITUTION. TO MEET INCREASINGLY STRINGENT EPA REQUIREMENTS, IT IS NECESSARY TO CONTINUALLY IMPROVE MAINTENANCE PRACTICES WITH UPDATED TECHNOLOGY THROUGH TECHNOLO ...

THIS WORK COMBINES THE PROBLEM STRUCTURING TOOLS AVAILABLE IN HYPERMEDIA PRODUCTS, WITH EXPERTISE REPRESENTATION APPROACHES FROM TRADITIONAL EXPERT SYSTEM TECHNOLOGY IN ORDER TO CREATE A DESIGN FOR AN ACQUISITION PROGRAM MANAGER'S ECP PREPARATION TOOL. THE TOOL WILL BE CAPABLE OF ASSISTING PMS IN NAVIGATING THE ECP PREPARATION PROCESS BY CONSIDERING MAJOR FEATURES OF THE GIVEN SYSTEM AND CHANGE, A ...

N/A

OPTICAL LOGIC DEVICES ARE SOUGHT BY MANY INSTITUTIONS TO BE USED IN DIGITAL OPTICAL SIGNAL PROCESSING SYSTEMS. THE DEVICES PROPOSED HERE ARE PARTLY A CONTINUATION IN THE EVOLUTION OF GAAS-BASED GATES, BUT THEIR INCORPORATION OF LASING CHARACTERISTICS PRODUCES REVOLUTIONARY ADVANTAGES IN SYSTEM RELIABILITY AND SIMPLICITY. THEY ARE BASED ON THE VERTICAL CAVITY SURFACE-EMITTING MICROLASERS WHICH THE ...

N/A

A SIMILAR METHOD TO MEASURING ICE ON A VIBRATING WIRE IS USED TO MEASURE PERSISTENT ICE ON SMALL STRUCTURES. THE MEASURMENT OF VIBRATION OF STRUCTURAL MEMBERS WILL UTILIZE AN ACCELEROMETER; IT PRODUCES A VERY SENSITIVE RESULTS FOR A WIDE DYNAMIC RANGE OF ATTACHED ICE MASS. A SMALL TAPPING MECHANISM WILL BE DEVELOPED TO INDUCE FREQUENCY VIBRATION. SIGNAL CONDITIONING AND PROCESSING ARE PROPOSED, IN ...
