ONE OF THE MOST COMMON PROBLEMS IN THE FIELDS OF SYSTEM DYNAMICS AND PATTERN RECOGNITION IS THE IDENTIFICATION OF THE DYNAMIC CHARACTERISTICS OF A SYSTEM ARE KNOWN THAN AN ACCURATE MATHERMATICAL MODEL COULD BE CONSTRUCTED AND A BETTER UNDERSTANDING OF THE BEHAVIOR OF THE SYSTEM COULD BE DEVELOPED. THIS WOULD HELP IMPROVE ITS DESIGN AND PERFORMANCE, MADE ITS IDENTIFICATION EASIER, FACILITATE INSPEC ...

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 TERRAIN HAZARD DETECTION SENSOR MEASURES THE CONTOUR OF THE TERRAIN IN FRONT OF A MOVING VEHICLE PROVIDING INFORMATION ABOUT TERRAIN SLOPE. IT MEASURES THE SIZE OF OBJECTS IN THE VEHICLE PATH AND ISSUES COMMANDS TO THE VEHICLE WHEN THE OBJECT IS TOO LARGE FOR THE VEHICLE TO PASS OVER AND ALSO MEASURES SIZES OF HOLES AND DITCHES IN THE VEHICLE PATH TO INSURE THAT THE VEHICLE CAN SAFELY PASS OVE ...

THE PROPOSED EFFORT WILL ASSESS THE FEASIBILITY OF USING COMPUTER AIDED DESIGN TECHNOLOGY TO PROJECT SYSTEM RELATED MANPOWER REQUIREMENTS. MANPOWER AND SKILL DETERMINATIONS HAVE HISTORICALLY OCCURED LATTE IN THE DESIGN PROCESS AND THUS HAVE HAD LITTLE IMPACT UPON SYSTEM DESIGN DECISIONS. THE INCREASING SCARCITY OF MANPOWER RESOURCES REQUIRES THAT THEY BE GIVEN AN INTERACTIVE ROLE IN SYSTEM DEVELOP ...

ALPHATECH, INC. PROPOSES TO DEVELOP AN INTEGRATED DECENTRALIZED MULTIVARIABLE CONTROL SYSTEM DESIGN METHODOLOGY FOR PROBLEMS RELATED TO THE ROBUST REAL-TIME CONTROL OF VERY LARGE FLEXIBLE SPACE STRUCTURES (VLFSS). A CRUCIAL NEED EXISTS FOR THE DEFINITION OF A SUPERIOR ARCHITECTURE OF SUCH CONTROL SYSTEMS AND THE REALTIME COORDINATION OF THE DECENTRALIZED MULTIVARIABLE CONTROLLERS. THE PROPOSED RES ...
