WITH INCREASING WAVEFORM COMPLEXITY AND EMITTER DENSITY IN THE TACTICAL ELECTROMAGNETIC SIGNAL ENVIRONMENT, THE JOB OF INTERCEPTING AND IDENTIFYING POTENTIALLY THREATS HAS OVERWHELMED THE CAPABILITIES OF CONVENTIONAL ESM RECEIVERS. THIS PROPOSAL DESCRIBES A PROGRAM TO STUDY THE APPLICATION OF ACOUSTIC CHARGE TRANSPORT (ACT) TECHNOLOGY TO ADVANCED ESM RECEIVER ARCHITECTURES. ACT IS AN EMERGING TECH ...

THE OPPORTUNITY EXISTS TO EXTEND THE CAPABILITIES OF THE USAF ADVANCED DYNAMIC ANTHROPOMORPHIC MANIKIN (ADAM) WHICH HAS BEEN DEVELOPED TO ASSESS THE INFLUENCE OF HUMAN RESPONSES ON EJECTION SEAT PERFORMANCE. THE MORE REALISTIC ARTICULATIONS AND VERTICAL SPINAL RESPONSE OF ADAM CAN BE SUPPLEMENTED WITH ADDITIONAL INSTRUMENTATION TO ALLOW THE DEFINITION OF INJURY PROBABILITY ASSESSMENT CRITERIA. SIN ...

CHRONIC NEEDS FOR HIGHER PERFORMANCE IN PRESENT AND FUTURE ARMY ROTOCRAFT/AIR-VEHICLE SYSTEMS MANDATE IMPROVEMENTS IN MATERIALS PROPERTIES. LIGHTWEIGHT METAL MATRIX COMPOSITES (MMC) INCLUDING MAGNESIUM AND ALUMINUM ARE AMONG THE BEST CANDIDATES TO FULFILL THE REQUIREMENTS THAT ENABLE LIGHTWEIGHT STRUCTURES, ADVANCED PROPULSION, TRANSMISSIONS, ROTORS, THRUST DEVICES, ETC. A UNIQUE COATINGS APPROACH ...

RESPONSIVE AND SENSITIVE FORCE CONTROL IS ESSENTIAL FOR SOPHISTICATED ROBOT TASKS SUCH AS ASSEMBLY AND FINE MANIPULATION. HOWEVER, THIS KIND OF CONTROL IS VERY DIFFICULT FOR MANIPULATORS DRIVEN BY ELECTRIC MOTORS WITH GEARED TRANSMISSIONS, PRIMARILY DUE TO FRICTION IN THE DRIVE TRAIN. YET THESE TYPES OF MECHANICAL SYSTEMS ARE OFTEN THE MOST PRACTICAL FOR MANY APPLICATIONS. TWO PRIMARY TYPES OF CON ...

THE PROPOSED PHASE I PROGRAM ADDRESSES PROBLEMS CURRENTLY INHIBITING DEVELOPMENT OF DIRECT METHANOL FUEL CELLS BY SUBSTITUTING HIGH AREA PEROVSKITE ELECTROCATALYSTS OF THE GENERAL COMPOSITION LN1-XAXCOO3, AND ACO1-XFEXO3 (WHERE LN - LA, ND, SM AND EU; A' = BA, SR, CA AND CE WITH O < X < 0.6; A - BA AND SR WITH O < X < O.4) FORDISPERSED NOBLE METAL ELECTOCATALYSTS CURRENTLY USED FOR THIS APPLICATIO ...

IN MODERN NAVAL COMBAT, LONG RANGE MISSILES CAN STRIKE FROM ANY DIRECTION AT ANY TIME. PERSONNEL INVOLVED IN THE WEAPONS CONTROL PROCESS HAVE APPROXIMATELY 30-60 SECONDS AFTER AN INCOMING MISSILE IS DETECTED TO REACH A DECISION ON HOW TO DEAL WITH THE INCOMING AIR THREAT.ICONS ARE ONE TYPE OF DECISION AID WHICH CAN HELP PERSONNEL INVOLVEDIN THE WEAPON CONTROL PROCESS REACT TO AND PROCESS INFORMATI ...

THIS PROPOSAL PRESENTS IDEAS AND A PLAN OF NEW TECHNOLOGY DEVELOPMENT FOR ADDRESSING PACKAGING AND OTHER TECHNOLOGY ISSUES IN ELECTRONIC SYSTEM DESIGN. THE PROPOSED WORK HAS AS ITS OBJECTIVE, THE IMPLEMENTATION OF A RAPID PROTOTYPING ENVIRONMENT THAT CONSISTS OF A SET OF TOOLS SUPPORTING HARDWARE DESIGN MEETING SPECIFIC RELIABILITY, PACKAGING, AND PERFORMANCE CONSTRAINTS. IT SUPPORTS ADDING CHANGE ...

IN THE CONTEXT OF INFORMATION MANAGEMENT, ONTOLOGY IS THE TASK OF EXTRACTING THE NATURE AND STRUCTURE OF A GIVEN EINGEERING, MANUFACTURING, BUSINESS, OR LOGISTICAL DOMAIN AND STORING IT INAN EXPRESSIVELY RICH, USABLE, COMPUTATIONALLY FEASIBLE REPRESENTATIONAL MEDIUM. AN ARRAY OF ONTOLOGY DATABASES IN USE ACROSS A WIDE VARIETYOF SUCH SYSTEMS WOULD REVOLUTIONIZE THE TASKS OF INFORMATION MANAGEMENT A ...
