N/A

AN ANALYTIC MODEL OF A WIDE FIELD, PHASED ARRAY IMAGING SYSTEM WILL BE DEVELOPED. THE MODEL IS BASED ON A MEASUREMENT SYSTEM CAPABLE OF ERROR MEASUREMENT DIRECTLY WITH RESPECT TO THE FINAL IMAGE PLANE. THE BEAMS FROM INDIVIDUAL SUBAPERTURES WILL BE COMPACTED AND CONFORMALLY MAPPED TO A DEMAGNIFIED PUPIL. WE WILL DEVELOP NONREDUNDANT, CODED APERTURE MASKS TO BE INSERTED AT THIS COMPACT PUPIL WHICH ...

N/A

A RESEARCH PROGRAM IS PROPOSED TO DETERMINE THE FEASIBILITY OF USING ADVANCED VACUUM INSULATIONS TO IMPROVE THE PRODUCTIVITY OF REFRIGERATED SHIPPING CONTAINERS WHILE AVOIDING THE ENVIRONMENTAL RISKS ASSOCIATED WITH CHLOROFLUOROCARBONS (CFC'S) IN FOAM INSULATION CURRENTLY BEING USED. ADVANCED VACUUM INSULATIONS, CURRENTLY UNDER RESEARCH AND DEVELOPMENT, DO NOT CONTAIN CFC'S AND HAVE VERYHIGH THERM ...

ION BEAMS WILL BE APPLIED IN SEVERAL ASPECTS OF PROCESSING ZNSE OPTICAL COMPONENTS. FIRST THE MATERIAL WILL BE MILLED, AND THEN IT WILL BE COATED USING ION ASSISTED DEPOSITION TECHNIQUES. REDUCED SCATTER FROM THE SUBSTRATE AND IMPROVE OPTICAL AND MECHANICAL PROPERTIES OF THE FILM ARE ANTICIPATED.

THIS EFFORT WOULD SCOPE THE LOGISTICS PLANNING EFFORTS REQUIRED FOR THE AIR FORCE TO SUPPORT AN ENTIRELY NEW CLASS OF HYPERSONIC VEHICLES,EFFORTS FROM BASE PLANNING TO OPERATIONAL MAINTENANCE SUPPORT. A MATRIX OF PROBABLE WORLD SETTINGS AND MISSION SCENARIOS WOULD SERVE AS A STARTING POINT TO IDENTIFY FIRST-ORDER LFIGHT SYSTEM MISSION REQUIREMENTS, SYSTEM REQUIREMENTS AND ASSOCIATED GROUND SUPPORT ...

THE ADVENT OF MULTI-HZ REP-RATED HPM SOURCES FOR EFFECTS TESTING PLACES SEVERE DEMANDS ON HPM DIAGNOSTIC SYSTEMS, ESPECIALLY IN FIELD USE. INCREASED EMPHASIS ON HIGH SHOT RATES AND THE DIFFICULTY OF QUICKLY SETTING UP AND DEBUGGING THE NECESSARY DIAGNOSTIC INSTRUMENTATION RESULTS IN FIELD EXPERIMENTS THAT OFTEN RECORD ONLY THE MOST BASIC DIAGNOSTIC INFORMATION, SUCH AS POWER DENSITY ENVELOPE AND F ...

N/A

DOWEL BARS HAVE TRADITIONALLY BEEN USED AS AN IMPORTANT LOADTRANSFER MECHANISM ON OUR FEDERAL HIGHWAYS. A SIGNIFICANT PROBLEM OCCURRS WITH THE USE OF THESE BARS DUE TO RUST AND RESULTANT SPALLING AND CRACKING CONCRETE. COMPOSITE REINFORCING BARS (CRB) HAVE BECOME WIDELY USED FOR CRACK CONTROL IN MANY REINFORCED CONCRETE STRUCTURES EXPOSED TO AGGRESSIVE ENVIRONMENTS. A LIMITED AMOUNT OF DATA IS AVA ...
