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 ...

THE OBJECTIVE OF THIS PHASE I RESEARCH IS TO IDENTIFY DESIGNCONCEPTS AND MATERIALS FOR FIBER REINFORCED PLASTIC (FRP) TENDON ANCHORAGE SYSTEMS IN POST-TENSIONED, PRESTRESSED CONCRETE STRUCTURES. FIBER REINFORCED PLASTIC TENDONS AND RELIABLE ANCHORS ARE NEEDED TO CREATE CORROSION FREE PRESTRESSED STRUCTURES RESULTING IN REDUCED MAINTENANCE COSTS AND AN INCREASED SERVICE LIFE FOR BRIDGE STRUCTURES. ...

THE OBJECTIVE OF THIS PHASE I RESEARCH IS TO DEVELOP THE METHODOLOGY NECESSARY TO PREDICT DAMAGE TO OPERATING ROCKET MOTORS AS A RESULT OF WARHEAD FRAGMENT IMPACT. METHODOLOGY, AS USED IN THIS WORK, MEANS THE DEFINITION AND SPECIFICATION OF NUMERICAL PROCEDURES, SEMI-EMPIRICAL FORMULAE, AND AVAILABLE EXPERIMENTAL DATA TO BE USED IN A PROCEDURE, THE RESULT OF WHICH IS THE CALCULATION OF KEY SYSTEM ...

N/A

A NOVEL, NONDESTRUCTIVE, LONGITUDINAL, CHARGED PARTICLE BEAMDIAGNOSTIC TOOL TO MEASURE LONGITUDINAL BEAM PROFILE AND CHARGE DENSITY DISTRIBUTION IS BEING STUDIED. THE CONCEPT IS BASED ON THE EFFECT OF MUTUAL ATTRACTIVE FORCES EXERTED BY THE PARTICLE BEAM ON A COLLINEAR ELECTRON BEAM OF MATCHEDVELOCITY. ANY MOVING CHARGED PARTICLE BEAM EXERTS AN ATTRACTIVE FORCE ON ELECTRONS IN ITS VICINITY. THIS F ...

BOTH ATMOSPHERIC AND HIGH-ALTITUDE NUCLEAR EXPLOSIONS WILL PRODUCE MAGNETIC SIGNALS THAT ARE DETECTABLE OVER VERY LARGE DISTANCE. AN UNDERGROUND EXPLOSION WILL ALSO PRODUCE A MAGNETIC SIGNAL, BUT IT IS DETECTABLE AT MUCH SMALLER DISTANCE. THIS IS BECAUSE THE UNDERGROUND FIREBALL IS INERTIALLY TAMPED BY THE MORE DENSE EARTH, AND BECAUSE THE LOW FREQUENCY ELECTROMAGNETIC WAVE IS STRONGLY ATTENUATED ...

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 ...

DEPLETED URANIUM PENETRATOR REMNANTS MAY BE PRESENT IN THE SOIL AND ULTIMATELY COULD BECOME DISPERSED IN THE AIR OR WATER, CREATING HEALTH HAZARDS. CURRENT TRENDS AND DECONTAMINATION PRACTICES MAY REQUIRE REMOVAL AND DISPOSAL OF VAST AMOUNTS OF SOIL TO ENSURE URANIUM REMOVAL. MOST OF THIS SOIL IS NOT CONTAMINATED, AND SHOULD NOT BE STORED AT HIGH COST IN THE LIMITED SPACE AVAILABLE FOR DISPOSAL OF ...
