THIS STUDY WILL EXAMINE THE FEASIBILITY AND PRACTICALITY OF UTILIZING CHARCOAL CLOTH IN A LIGHT-WEIGHT SOLAR POWERED DISTILLATION PURIFICATION DEVICE INCORPORATING CHARCOAL CLOTH AS THE ENERGY ABSORBENT WATER WICK. IN THIS PROPOSED DEVICE, IT IS EXPECTED THAT THE CHARCOAL CLOTH WILL ACT NOT ONLY AS THE DISTILLATION MEDIA, BUT WILL ALSO REMOVE OBJECTIONABLE ODORS, CO-DISTILLABLE ORGANIC COMPOUNDS A ...

THERE IS A GREAT NEED FOR HF BROADBAND TRANSMITTING ATENNA FOR COMMUNICATIONS AND JAMMING APPLICATIONS. THE MAJOR DISADVANTAGES OF PRESENT NARROW BAND ANTENNAS ARE: SLOW TUNING COUPLERS LIMIT JAMMING SYSTEM RESPONSE TIME AND OPERATIONAL BANDWIDTHS; TO ACHIEVE RESONABLE EFFICIENCIES LARGE ATENNA STRUCTURES ARE REQUIRED, ESPECIALLY AT THE LOWER FREQUENCIES; REQUIRE GOOD GROUND CONDUCTIVITY TO MAINTA ...

A SONOBUOY ON THE BOTTOM OF THE OCEAN CAN ACHIEVE LONG DETECTION RANGES BY USE OF THE RELIABLE ACOUSTIC PATH (RAP). BY PUTTING AN ACOUSTIC SIGNAL PROCESSOR IN THE BUOY TO DO SPECTRUM ANALYSIS AND CONTACT REPORT GENERATION, THE DATA TRANSMITTED TO SURVEILLANCE AIRCRAFT CAN BE REDUCED TO SHORT BURSTS ON A SCHEDULE THAT MEETS PATROL AIRCRAFT REVISIT REQUIREMENTS FOR INCREASED AIRCRAFT UTILIZATION AT ...

THERE IS AN INCREASING NEED FOR LONG RANGE (200KM) APPROXIMATELY 10 BPS RATE ACOUSTIC COMMUNICATION AT LOW BIT ERROR RATES IN THE COMMAND AND CONTROL OF ACOUSTIC SURVEILLANCE SYSTEM ELEMENTS, UNDERWATER VEHICLES AND SENSORS. SIMULATED FISH NOISE, CODED TONE AND MULTITONE CW SIGNALS HAVE BEEN USED WITH VARYING SUCCESS. ONLY THE M-ARY, MULTITONE, LONG BAND LOW FREQUENCY WAVEFORMS ARE PRACTICAL FOR L ...

THIS PROPOSAL ADDRESSES ELINT\ESM SIGINAL PROCESSING RESEARCH FOR REAL-TIME DETECTION IDENTIFICATION AND LOCATION OF THREAT RADAR EMITTERS ON THE BATTLEFIELD. GIVEN THE PREDICTED FUTURE GROWTH OF PULSE DENSITIES IN THE ELECTRONIC ENVIORNMENT, AND THE PROLIFERATION OF AGILE RADARS, IT IS NECESSARY TO DEVELOP MORE SOPHISTICATED ELINT\ESM SYSTEMS. AN ARCHITECTURE IS PRESENTED FOR A COMPUTER-BASED, AD ...

THIS RESEARCH SHALL FOCUS ON TWO IMPROVEMENTS TO THE CURRENTSTATE OF MODELING AND SHAPE CONTROL OF LARGE SPACE STRUCTURES: (1) THE USE OF FREQUENCY DOMAIN/SPECTRAL FACTORIZATION METHODS FOR THE DEVELOPMENT OF SHAPE CONTROL LAWS: AND (2) THE USE OF ADVANCED METHODS, INCLUDING HOMOGENIZATION, OR THE REDUCTION OF COMPLEXITY OF THE MODELSOF LARGE SPACE STRUCTURES WITH REGULAR LATTICE STRUCTURE. THE AP ...

THIS EFFORT ADDRESSES THE REQUIREMENTS AND DESIGN ISSUES SURROUNDING THE DEVELOPMENT OF SECURE COMPUTER NETWORKS. WEPROPOSE A DESIGN FOR A SECURE COMPUTER NETWORK WHICH INCORPORATES NETWORK SECURITY DEVICES. THIS NETWORK IS EXPECTED TO PROVIDE A PROCESSING ENVIRONMENT WITH ACCEPTABLEPERFORMANCE WHERE SHARING OF CLASSIFIED INFORMATION MAY BE ACCOMPLISHED WITH CONFIDENCE IN THE PRESERVATION OF THE S ...

THIS STUDY WILL EXAMINE THE FEASIBILITY AND PRACTICALITY OF UTILIZING HYDROGEN PEROXIDE OR HYDROGEN PEROXIDE COMPOUNDS/SOLUTIONS AS A LIGHT WEIGHT, COMPACT OXYGEN SOURCE FOR EMERGENCY BREATHING APPLICATIONS.

NON-DESTRUCTIVE TESTING RESEARCH HAS BEEN PRIMARILY CONCEREND WITH DEFECT DETECTION AND CHARACTERIZATION WITH RELATIVELY LITTLE EFFORT ON NDT TECHIQUES FOR MEASURING STRESS, PREDICTING FATIGUE DAMAGE PRIOR TO CRACKING AND MONITORING OF CRACK PROPAGATION IN CRITICAL AIRCRAFT COMPONENTS. THESE PROBLEMS ARE OF SIGNIFICANCE TO THE AIRCRAFT INDUSTRY AND TO THE NAVY BECAUSE OF THE POTENTIAL FAILURE DUE ...

GAASP SOLAR CELLS PLACED ON TOP OF CONVENTIONAL SILICON SOLAR CELL ARRAYS CAN INCREASE THE ENERGY CONVERSION EFFICIENCY OF THE SYSTEM AS MUCH AS 100%. ASTROPOWER DIVISION OF ASTROSYSTEMS, INC. PROPOSES TO DEVELOP A HIGH BAND GAP TOP SOLAR CELL FOR ATTACHMENT TO CONVENTIONALS ILICON SOLAR CELLS. TRANSPARENT GAP SUBSTRATES WILL BE USED WITH EPITAXIALLY GROWN LAYERS OF GAASPH HAVING A BAND GAP OF 1.7 ...
