Reliability and structural safety are major concerns in the design of next-generation space transportation and systems. Acellent Technologies, Inc. Proposes to develop and innovative, cost-effective and reliable built-in structural diagnostic system forlight-weight large-scale space structures made of composite materials to monitor their integrity during service thereby prolonging life span, red ...

A 24-month Phase II project is proposed to develop and implement models that capture the fidelity of high fidelity physics-based (HFPB) models in a fast-running format. It is anticipated that such models will be incorporated in certain modules of theModular Effectiveness/Vulnerability Assessment (MEVA) code developed for and currently used by the Air Force for assessing munitions effectiveness an ...

AN ADAPTIVE ARRAY SIGNAL PROCESSOR CAPABLE OF ADAPTIVELY NULLING MULTIPE SIDELOBE JAMMERS AND SIDELOBE DISTRIBUTED AND DISCRETE GROUND CLUTTER RETURNES COMPETING WITH THE TARGET RETURN, IN AI-LOW OBSERVABLE TARGET DETECTING MEDIUM-PRF RADARS IS THE SUBJECT OF A DESIGN STUDY. THE ASI-DEVELOPED AIRBORNE RADAR ADAPTIVE ARRAY SIMULATION TEST BED (IMPLEMENTED IN A PC-286 COMPUTER) IS PROPOSED TO BE USE ...

LONG WAVELENGTH GROUND-BASED MULTISTATIC RADAR SYSTEMS WHICH MAY BE IN THE HF, VHF, OR UHF BANDS OFFER POTENTIAL SOLUTIONS TO THE PROBLEMS ASSOCIATED WITH PERFORMING THE TACTICAL ARMY MISSION OF FOREWARD AREA AIR DEFENSE (FAAD) AND WEAPONS LOCATION WITH MONOSTATIC SHORT WAVELENGTH RADARS. HOWEVER, SIGNIFICANT PROBLEMS ARE ALSO INTRODUCED WITH THE USE OF THESE LONG WAVELENGTH BISTATIC RADAR SYSTEMS ...

WE PROPOSE TO DEVELOP A SIMPLE, PORTABLE, ONE-STEP ASSAY FOR THE DETECTION OF MYCOPLASMA PNEUMONIAE AND INFLUENZA A WHICH CAN BE PERFORMED INDEPENDENT OF A SOPHISTICATED LABORATORY BY UNTRAINED OR SEMI-SKILLED PERSONNEL. THIS SIMPLE, ONE-STEP METHOD IS CALLED AN OPTICAL BIOASSAY (OBA) AND UTILIZES AN INEXPENSIVE LASER AND PHOTODETECTOR TO DETECT AN ANTIGEN-ANTIBODY BINDING EVENT. ANTIBODY IS COVAL ...

AUTOMATIC AIDS FOR SITUATION ASSESSMENT, GENERAL INFORMATION FUSION, DECISION MAKING AND PLANNING ARE VULNERABLE TO DECEPTION IN ADVERSARIAL SITUATIONS. COUNTER-DECEPTION CAPABILITIES TO DETECT POSSIBLE DECEPTIVE ACTIONS AND OBTAIN THE CORRECT ASSESSMENT ARE NEEDED TO PRESERVE THE EFFECTIVENESS OF THESE AIDS. THE PROPOSED RESEARCH WILL CREATE TECHNOLOGICAL SUPPORT SO THAT THE EFFECTS OF DECEPTION ...

SUCCESSFULLY APPLYING MODEL-BASED REASONING TO REAL WORLD VISION PROBLEMS (E.G. AUTOMATIC TARGET RECOGNITION ?ATR?) REQUIRES ACCURATE REPRESENTATION OF COMPLEX RELATIONSHIPS AMONG THINGS IN THE WORLD AND OBSERVABLE IMAGE FEATURES. EVIDENCE ACCRUAL TECHNIQUES MUST BE ABLE TO OPERATE OVER THESE RELATIONSHIPS WITH LITTLE LOSS IN INFORMATION. CURRENT TECHNIQUES SUCH AS BAYESIAN NETWORKS SHOW PROMISE, ...

HIGH-RESOLUTION COMPUTED TOMOGRAPHY SHOWS SIGNIFICANT PROMISE IN AIDING THE DEVELOPMENT OF ADVANCED COMPOSITE MATERIALS WHICH ARE IMPORTANT IN IMPROVING AIRCRAFT PERFORMANCE. NONDESTRUCTIVE IMAGING OF THE INTERNAL STRUCTURE OF THESE MATERIALS CAN HELP IN IMPROVING PROCESSING QUALITY, IN DEVELOPING PERFORMANCE MODELS, AND IN EVALUATING MANUFACTURED COMPONENTS. CURRENT IMAGING PERFORMANCE COULD BE S ...

THE DEVELOPMENT OF A WAFER-LEVEL TESTING TECHNIQUE FOR MULTIGIGAHERTZ GAAS DIGITAL INTEGRATED CIRCUITS TO CHARACTERIZE THE TRANSIENT-RADIATION-INDUCED UPSET LEVEL IS PROPOSED. THIS CONCEPT WILL ALLOW THE OPTIMIZATION OF THE UPSET LEVEL IN HIGH PIN-OUT DENSITY CIRCUITS USING AN ON-SITE, QUICK TURNAROUND PROCEDURE FOR TECHNOLOGY DEVELOPMENT AS WELL AS CIRCUIT SCREENING. THIS NONDESTRUCTIVE TECHNIQUE ...

THE OBJECTIVE OF THE PROPOSED WORK IS TO DEVELOP TECHNIQUES FOR DETECTING AND QUANTIFYING WEAK OR "KISSING" DEBONDS IN SOLID ROCKET MOTORS. THE PROPOSED TECHNIQUE IS BASED ON X-RAY COMPUTED TOMOGRAPHY.IT IS INNOVATIVE BECAUSE IT DOES NOT REQUIRE THAT ANY GAPS IN THE DEBOND AREA BE RESOLVED. INSTEAD, IT RELIES ON MEASUREMENTS OF THE PROPELLANT DILATATION NEAR THE BONDED INTERFACE TO SHOW WHETHER LO ...
