A PORTABLE DATA ACQUISITION AND INSTRUMENTATION SYSTEM (DAISY) HAS BEEN DEVELOPED BY AS&M, INC. FOR WIND-TUNNEL TESTS. IT INCORPORATES A UNIQUE AND PATENTED TECHNIQUE TO ACCURATELY IDENTIFY AND DEMARCATE REGIONS OF FLOW SEPARATION, REATTACHMENT, AND THE LEADING-EDGE STAGNATION POINT. SIMULTANEOUSLY, LAMINAR-TO-TURBULENT TRANSITION AND THE SPECTRAL CONTENT OF THE MOST AMPLIFIED DISTURBANCES IN THE ...

THE OBJECTIVE IS TO CREATE GROUP DECISION SUPPORT SYSTEM (GDSS) SOFTWARE WHICH PERMITS ARMY PERSONNEL TO QUICKLY MAKE DECISIONS, EVEN WHEN THE DECISION MAKERS ARE LOCATED AROUND THE WORLD. THE SOFTWARE WOULD OPERATE ON PERSONAL COMPUTERS, SUCH AS THE ZENITH 148, AND BE COMPATIBLE WITH THE ARMY'S WORD-PROCESSORS AND OTHER SOFTWARE. SPECIFIC PHASE I OBJECTIVES WILL BE TO DEFINE AND PROGRAM THE FEATU ...

N/A

THE OBJECTIVE OF THIS PHASE I RESEARCH IS TO DEVELOP A COMPUTATIONAL PROCEDURE FOR PREDICTING THE LIFE AND RELIABILITY OF COMPOSITE STRUCTURAL PANELS SUBJECTED TO COMPLEX DYNAMIC LOADS FROM ACOUSTIC, AERODYNAMIC, AND THERMAL ENVIRONMENTS. THE PROPOSED RESEARCH USES A NONCLASSICAL VARIATIONAL APPROACH AND A TIME DOMAIN MONTE CARLO METHOD TO DEVELOP ANALYTICAL EQUATIONS OF HIGH ACCURACY AND EFFICIEN ...

THEATER-LEVEL MISSION ANALYSIS COMPUTER MODELS ARE GENERALLY RUNTIME EFFICIENT, YET LACK THE CAPABILITY OF MODELING EVENTS IN DETAIL. IN MOST SCENARIOS, CERTAIN EVENT OUTCOMES ARE HIGHLY SENSITIVE TO DETAILED MODELING PARAMETERS NOT AVAILABLE IN THE THEATHER-LEVEL MODEL. A SOLUTION TO THIS PROBLEM IS TO INTERFACE THE THEATER-LEVEL MODEL TO A LOWER-LEVEL MODEL THAT CAN SIMULATE PARTICULAR EVENTS IN ...

N/A

THIS PROPOSAL DESCRIBES A PLAN AND METHODOLOGY FOR DETERMINING THE TECHNICAL MERIT AND FEASIBILITY OF DEVELOPING AN INTELLIGENT ONBOARD MISSION PLANNING SYSTEM FOR ADVANCED ARMY ROTORCRAFT. ONBOARD MISSION PLANNING, ALTHOUGH EXTREMELY DIFFICULT, IS ALREADY NECESSARY IN SOME ARMY OPERATIONS, AND THE REQUIREMENTS WILL BECOME OVER MORE PRESSING IN THE FUTURE. AN INTELLIGENT ON-BOARD SYSTEM IS NEEDED ...

THEORETICAL CHEMISTRY TECHNIQUES ARE USED TO PROVIDE FUNDAMENTAL UNDERSTANDING OF THE MOLECULAR REQUIREMENTS FOR ACHIEVING CONDUCTIVE PROPERTIES IN POLYMER SYSTEMS AND IN A LATER STAGE TO ADDRESS THE REQUIREMENTS FOR ACHIEVING NONLINEAR OPTICAL PROPERTIES. IT IS PROPOSED TO DEDUCE THE CONDUCTION MECHANISM BY CALCULATING THE CONDUCTIVITY TENSOR DIRECTLY AND ANALYZING THE DIFFERENT CONTRIBUTIONS TO ...

THE PHASE I PROJECT RESULTED IN THE DEVELOPMENT OF SEVERAL TATTOO PIGMENTS THAT WERE EFFECTIVE IN IDENTIFYING B6C3F1 BROWN MICE IN A 3-MONTH STUDY. THESE PIGMENTS DID NOT AFFECT GROWTH OR MORTALITY; HOWEVER, ONE PIGMENT WAS CYTOTOXIC TO IN VITRO MOUSE LYMPHOMA CELLS. THE PHASE II PROJECT WILL INVOLVE FORMULATION OF STABLE PIGMENTS AND 2-YEAR TATTOO READABILITY STUDIES IN B6 MICE USING THE BEST PIG ...

THIS PROPOSAL WILL DEMONSTRATE (IN 2" TO 4" SIZE), A NOISE REDUCING TRIM THAT CAN BE UTOLIZED IN ROTARY CONTROL/ON-OFF BALL VALVES. THIS VALVE TRIM ADDRESSES NOISE AT THE SOURCE. THE BASIC DESIGN HAS A VARIABLE IMPEDENCE TRIM TO CAUSE A HIGH IMPEDENCE AT LOW ANGLES OF OPENING AND LOW IMPEDENCE (VERY LITTLE FLOW RESTRICTION) AT LARGE OPENING ANGLES. IT IS AN IDEAL VALVE FOR PRESSURIZATION/DE-PRESSU ...
