A SYSTEM IDENTIFICATION TECHNICAL IS PROPOSED FOR NON-DESTRUCTIVE TEST TO DETECT UNBOUNDS IN LARGE BONDED COMPONENTS. THE TECHNIQUE USES THE SYSTEM'S TIME RESPONSE DATA DUE TO RANDOM INPUT EXCITATION. SYSTEM'S EIGENVALUES AND EIGENVECTORS ARE RETRIEVED FROM THE TIME RESPONSES AND USED FOR THE CONSTRUCTION OF ACCURATE SYSTEM MATHEMATICAL MODELS. SYSTEM'S CHANGE DUE TO CRACKS, VOIDS, UNBONDS BETWEEN ...

METHODS ARE DESPERATELY NEEDED TO DISCERN THE STRUCTURAL INTEGRITY OF CRITICAL COMPONENTS OF WEAPON SYSTEMS SUCH AS PRESSURE VESSEL CASES. AT THIS TIME, NO TECHNIQUE EXISTS WHICH PERMITS A GLOBAL MONITORING OF THE OPERATIONAL READINESS OF ANY STRUCTURES, INCLUDING COMPOSITE MOTOR CASES. THE RANDOMDEC PROCEDURE, WHICH IS PLANNED TO BE UTILIZED UNDER THIS PROPOSED STUDY, APPEARS TO HAVE THE CAPABILI ...

THE TECHNICAL OBJECTIVE OF THE PROPOSED RESEARCH IS TO DETERMINE THE EXTENT TO WHICH LANGUAGE INSTRUCTION CAN BE IMPLEMENTED AND ENHANCED BY THE EMERGING CAPABILITIES OF COMPUTER SYSTEMS PROVIDING PERSONALIZATION, MULTIMEDIA PRESENTATION, AND A HIGH DEGREE OF HUMAN/MACHINE INTERACTION. IF SUCCESSFUL, THIS WORK WILL LEAD TO NEW TECHNIQUES FOR TEACHING LANGUAGES, TECHNIQUES WHICH WILL OVERCOME CURRE ...

THE PHASE I EFFORT IS TO ESTABLISH THE TECHNICAL MERIT AND FEASIBILITY OF USING VOICE MESSAGING TECHNOLOGY AS AN INST INSTRUCTIONAL TOOL FOR TRAINING HANDICAPPED PEOPLE WHO DE DESIRE TO START A BUSINESS OF THEIR OWN. THE HYPOTHESIS OF THE STUDY IS: USING VOICE MESSAGING TECHNOLOGY, IT IS POSSIBLE TO DEVELOP AN EFFECTIVE TRAINING PROGRAM FOR A NATIONWIDE AUDIENCE OF NEW AND FUTURE HANDICAPPED ENTRE ...

SHIPS HAVE LONG BEEN DESIGNED TO EMPIRICAL FORMULATE THAT DO NOT REPRESENT REALISTIC CONDITIONS FOR MODERN NAVAL VESSELS IN EXTREME SEA CONDITIONS. AS A CONSEQUENCE, SHIPS FREQUENTLY SUFFER EXPENSIVE DAMAGE IN HEAVY SEAS. THE OBJECTIVE OF THE PROPOSED RESEARCH IS TO ATTEMPT TO IDENTIFY SPECIFIC EXAMPLES OF EXTREME WAVES OF THE TYPE THAT HAVE BEEN KNOWN TO CAUSE SPECIFIC TYPES OF DAMAGE. AS FAR AS ...

RECENT WORK PERFORMED AT NSWC, WHITE OAK, MD HAS SHOWN THAT CONVENTIONAL LAUE X-RAY TRANSMISSION PATTERNS OBTAINED BY FILM METHODS GIVE AN INDICATION OF GROWN-IN MICROSTRUCTURAL DEFORMATION OF HOLSTEN CLASS D RDX ENERGETIC MATERIALS. THE OBJECT OF THIS STUDY IS TO DETERMINE IF X-RAY LAUE PATTERNS FROM RDX AND/OR HMX ILLUSTRATING SEVERE MICROSTRUCTURAL DEFORMATION ALSO CORRESPOND TO POOR PERFORMANC ...

THE PROPOSED RESEARCH WORK IS A RESPONSE TO THE NATIONAL DEFENSE EFFORT OF THE UNITED STATES OF AMERICA TO ULTIMATELY MANUFACTURE A LOW COST, RELIABLE AND EFFECTIVE TURNABLE FREQUENCY FAR INFRARED (IR) DETECTOR THAT CAN BE PLACED UPON BOTH OUR OFFENSIVE AND DEFENSIVE WEAPONS SYSTEMS. THE MATERIAL THAT WILL BE INVESTIGATED IS THE "SEMIMAGNETIC" SEMICONDUCTOR HG 1-X MN X TE, A SISTER COMPOUND TO HG ...
