MICROCOMPUTER DATABASE MANAGEMENT SYSTEMS HAVE SIMPLIFIED THE TASK OF UPDATING AND MAINTAINING LARGE QUANTITIES OF INFORMATION. A PARALLEL DEVELOPMENT HAS BEEN THE EMERGENCY OF COMPUTER-AIDED DESIGN SYSTEMS THAT ENABLE AN OPERATOR TO EXAMINE AND MANIPULATE DRAWINGS. THE PROPOSED RESEARCH WILL INVESTIGATE THE POSSIBILITY OF COMBINING THE ADVANTAGES OF THE DATABASE MANAGEMENT SYSTEM WITH THOSE OF CO ...

A SYSTEMATIC INVESTIGATION OF THE IONIZED CLUSTER BEAM (ICB) DEPOSITION TECHNIQUE IS PROPOSED. THE ICB METHOD ALLOWS A BROAD RANGE OF CONTROL OVER THE SURFACE MOBILITY OF DEPOSITED ATOMS AND HAS BEEN APPLIED SUCCESSFULLY TO A VARIETY OF THIN FILM MATERIALS. HOWEVER, A NUMBER OF FACTORS HAVE HAMPERED U.S. RESEARCH IN THIS AREA, SO THAT THERE IS NOT NOW A SUFFICIENT BASE OF KNOWLEDGE OR EXPERIENCE T ...

THE PROPOSED PROGRAM OFFERS AN INNOVATIVE APPROACH FOR PROTECTING A BATTLE GROUP FROM ATTACKS BY ADVANCED ANTI-SHIP MISSILES. SPACIALLY DISTRIBUTED COUNTERMEASURES, OF VARIOUS TYPES, ARE DEPLOYED IN A COORDINATED MANNER SO AS TO COUNTER ALL PHASES AND ASPECTS OF THREAT MISSILE WEAPON SYSTEMS. THESE COORDINATED COUNTERMEASURES TECHNIQUES ARE APPLIED SEQUENTUALLY AND THEIR EFFECTIVENESS AGAINST EACH ...

A HIGH TEMPERATUE WARNING SWITCH FOR ENGINE COOLING SYSTEMS IS CONCEIVED WHICH PROVIDES WARNING AT A RELATIVELY LOWER TEMPERATURE LEVEL (E.G. 212 DEGREE FAHRENHEIT) IF THE SYSTEM PRESSURE IS BELOW 7 PSIG AND AT A HIGHER TEMPERATURE LEVEL (E.G. 225 DEGREES FAHRENGEIT) IF THE SYSTEM PRESSURE IS ABOVE 7 PSIG. IN THE EVENT OF COOLING SYSTEM PRESSURE LOSS, THIS DUAL-LEVEL, PRESSURE DEPENDENT WARNING SW ...

AN ALGORITHM IS DEVELOPED FOR APPLICATION IN A RAY TRACING PROGRAM TO PROVIDE THE AMPLITUDE, POLARIZATION, AND PHASE OF AN ELECTROMAGNETIC WAVE REFLECTED FROM A DIELECTRIC BODY. TWO DIFFERENT CONFIGURATIONS ARE USED. THE FIRST CONSISTS OF AN ABSORPTIVE DIELECTRIC BODY AND THE SECOND OF A DIELECTRIC BODY COATED WITH A ABSORPTIVE LAYER. THE ALGORITHM IS BASED ON AN EXACT SOLUTION TO THE BOUNDARY VAL ...

SURFACE ROUGHNESS AFFECTS BOTH THE SHAPE OF AN ULTRASONIC IMPULSE TRANSMITTED THROUGH AN INTERFACE AND ITS POWER SPECTRUM. TO FULLY APPLY ADVANCED SIGNAL ANALYSIS TECHNIQUES TO DETERMINING QUANTITATIVE INFORMATION ABOUT DEFECTS AND IMPERFECTIONS IT IS NECESSARY TO COMPENSATE FOR THE FREQUENCY DEPENDENT EFFECTS INTRODUCED BY SURFACE ROUGHNESS. THIS PROJECT PROPOSES TO MODEL SURFACE ROUGHNESS TO OBT ...
