ADIABATICS, INC. IS PLEASED TO PROPOSE A RESEARCH PROGRAM TO DESIGN AN OPTIMUM PISTON FOR A HIGH TEMPERATURE MILITARY ENGINE. ADIABATICS, INC. HAS BEEN CONDUCTING A PROGRAM FOR TACOM TITLED "DEVELOPMENT OF TRIBOLOGICAL SYSTEMS AND ADVANCED HIGH TEMPERATURE IN-CYLINDER COMPONENTS FOR ADVANCED HIGH TEMPERATURE DIESEL ENGINES" FOR THE PAST FIVE YEARS. BASED ON OUR EXPERIENCE WITH DESIGNING COMPONENTS ...

CURRENTLY, AIRBREATHING PROPULSION SYSTEMS WHICH OPERATE IN THE HIGH SUBSONIC REGIME ARE EXPENSIVE, COMPLEX, HEAVY AND USE PERISHABLE FUELS. TO OVERCOME THESE LIMITATIONS, A NOVEL PROPULSION CONCEPT BASED ON A PULSE DETONATION ENGINE (PDE) OR A CONVENTIONAL RAMJET COMBUSTOR (CRC) COUPLED WITH A BORON SOLID FUELED HYBRID GAS GENERATOR (HGG) IS PROPOSED. THE INNOVATION DRAWS FROM RECENT SUCCESSES IN ...

RECENT DEVELOPMENTS IN INTERNATIONAL RELATIONS HAVE LED TO THE NECESSITY FOR BATTLE READINESS IN A REGION WHERE CHEMICAL OR BIOLOGICAL WARFARE AGENTS HAVE BEEN EMPLOYED IN THE PAST. AT PRESENT, LITTLE ATTENTION HAS BEEN PAID TO METHODS FOR IDENTIFYING THE CHEMICAL OR BIOLOGICAL CONDITIONS OF FREE STANDING STRUCTURES. THIS PROPOSAL SUGGESTS THE DEVELOPMENT OF OPTICAL SENSORS BASED ON THE INTERACTIO ...

THE IUSS HAS AN URGENT NEED FOR MORE EFFICIENT METHODS OF SIGNAL PROCSSSING. TO MEET THIS END, SUBMARINE DETECTION AND CLASSIFICATION SYSTEMS MUST BE REEXAMINED AND MODIFIED. THIS PROPOSAL EXAMINES THE POTENTIAL OF AN INNOVATIVE TECHNIQUE CALLED FRACTAL IMAGE ANALYSIS TOAID OPERATORS TO ACCURATELY AND EFFICIENTLY DETECT AND CLASSIFY SUBMARINES IN A PASSIVE SONAR ENVIRONMENT. FRACTAL IMAGE ANALYSIS ...

A NOVEL APPROACH TO LOW COST SHAPED BEAM SCANNING FOR MONOLITHIC STRUCTURES IS PROPOSED. THE TECHNIQUE MAKE USE OF RADOME MATERIAL COSTING OF THE CONVENTIONAL MONOLITHIC STRUCTURE; THE RADOME ITSELF IS COMPOSED OF A COMPOSITE OF HIGH DIELECTRIC CONSTANT/MAGNETICALLY SENSITIVE MATERIAL-REFERED TO AS "DIELECTROMAGNETIC" (DEM) MATERIAL. THE DEM MATERIAL CHARACTERISTICS ARE DESIGNED TO PROVIDE A SHAPE ...

Due to the limited space and the need for flush mounting charactistics, a new and novel series of antenna systems for communications and ECM is proposed. It is proposed to use dielectromagnetic (DM) materials to miniaturize antennas and for RF DM lens to focus the RF signals into the below the surface antennas. An Astron pioneered subminiature direction finding system using DM materials, will be m ...

Monopole and dipole antennas have been determined to radiate most efficiently when the size of the antenna is proportional to the frequency being transmitted or received, i.e. one-quarter, one-half or one wavelength. As the operating frequency is varied from that ideal frequency nulls begin to develop which threaten the integrity of the communication link. Experience has shown that small excursion ...

The vibration signatures (mechanical, acoustic, and electromagnetic) produced by machine components may be used for machinery diagnostics. By regularly measuring vibration levels, defects can be detected and diagnosed before causing extensive damage or failure, a process known as predictive maintenance. The main advantage of predictive maintenance is that problems can be identified without disasse ...

A LARGE DEPLETION OF ATMOSPHERIC OZONE IS OCCURRING EACH AUSTRAL SPRING OVER ANTARCTICA. REFERRED TO AS THE OZONE HOLE PROBLEM, THE CONCERN IS THAT OZONE-POOR AIR FROM THE ANTARCTIC STRATOSPHERE IS MIXING WITH AIR AT LOWER LATITUDES. FURTHERMORE, THERE ARE INDICATIONS THAT THE SIZE OF THE HOLE COULD INCREASE AND WILL CONTINUE TO FORM FOR THE NEXT 90 YEARS EVEN IF CFC RELEASES ARE CONTROLLED. SUCH ...

THE PROPOSED RESEARCH ASKS HOW DECISION MAKING CAN BE SUPPORTED AND IMPROVED IN THE AUTOMATIC TARGET RECOGNITION ENVIRONMENT, IN THE LIGHT OF (A) BIASES IN HUMAN DECISION BEHAVIOR AND (B) NATURAL HUMAN REPRESENTATIONAL AND REASONING STRATEGIES. WE WILL (1) STUDY ATR DETECTION, IDENTIFICATION, TRACKING, AND PRIORITIZATION TASKS IN TERMS OF THE MIX OF ANALYTICAL, RECOGNITIONAL, AND METACOGNITIVE DEM ...
