THIN FILM TYPE PERMANENT MAGNET MAY OFFER AN ATTRACTIVE ALTERNATIVE TO BULK MAGNETS FOR BIASING VARIOUS MICROWAVE DEVICES IN RADAR AND COMMUNICATION DEVICES. SPUTTERING HAS BEEN USED TO FABRICATE THIN FILMS (1-3 MICRONS) OF PERMANENT MAGNETS BASED ON SM-CO AND FE-ND-B ALLOYS HAVING HIGH ENERGY PRODUCTS AND HIGH COERCIVITIES, HOWEVER, FOR MSW DEVICES, SUFFICIENTLY THICK (100-150 MICRONS) PERMANENT ...

NIOBIUM ALUMINIDE (NBAL[3]) BASED MONOLITHIC AND COMPOSITE MATERIALS HAVE POTENTIAL AIR FORCE APPLICATIONS IN THE TEMPERATURE RANGE 2000-3000 DEG F IN ADVANCED GAS TURBINE ENGINES AND ADVANCED TRANSATMOSPHERIC FLIGHT VEHICLES. NBAL(3) BASED MATERIALS HAVE PROVED TO BE RATHER FORMIDABLE MATERIALS TO PROCESS BECAUSE OF ITS EXTREME BRITTLENESS. FOR SUCCESSFUL PERFORMANCE DURING LONG TERM ELEVATED TEM ...

GAMMA-TIAL BASED INTERMETALLIC ALLOYS HAVE POTENTIAL AIR FORCE APPLICATIONS FOR TEMPERATURES UP TO 1800 DEG F. ALLOY DEVELOPMENT RESEARCH HAS SHOW THAT COMPOSITIONS (IN ATOM %) SUCH AS TI-48AL-2MN-2NB EXHIBIT SOME ROOM TEMPERATURE DUCTILITY AND GOOD HIGH TEMPERATURE OXIDATION RESISTANCE. HOWEVER, RESEARCH IS NECESSARY TO OPTIMIZE THE ROOM TEMPERATURE MECHANICAL PROPERTIES SUCH AS DUCTIVITY, TOUGHN ...

Hexavalent chromium, Cr(VI), in the usual form of oxo species, is used in manyindustrial processes and products. As a consequence, Cr(VI)= containingcompounds are often found in wastewater and contaminated sites. Since Cr(VI) isconsidered highly toxic and carcinogenic, it is extremely important to have areliable, easy-to-use, sensitive monitor for determining Cr(VI) concentrationsin process, on ...

Electromechanically Actuated (EMA) valves are generally defined as valves operated by electronically controlled motor drive systems, rather than by valved hydraulic or pneumatic systems. Morotta Scientific Controls reviewed the current state-of-the-art for EMA ball valves in the cryogenic rocket propulsion industry and performed a trade study comparing these valves to a new and innovative valve d ...

PERDEUTERATED SYNTHETIC OILS HAVE RECENTLY BEEN SHOWN TO EXHIBIT EXCEPTIONAL CHARACTERISTICS IN TERMS OF STABILITY TO HIGH TEMPERATURES AND OXIDIZING ENVIRONMENTS. IN SPITE OF THESE ADVANTAGES, THE HIGH COSTS OF CHEMICAL PERDEUTERATION HAVE RESTRICTED THE USE OF THESE COMPOUNDS TO CIRCUMSTANCES IN WHICH INSTRUMENT "DOWN-TIME" DUE TO LUBRICANT FAILURE IS VERY COSTLY OR A THREAT TO NATIONAL SECURITY ...

THE PROPOSED APPROACH WILL AUTOMATE PRODUCTION OF FREQUENCY ASSIGNMENTS, GRAPHS OF SPECTRUM OCCUPANCY, AND PROBABILITIES OF SUCCESSFUL COMMUNICATION. OBTAINING THE NEDDED DATA AND PROCESSING IT TO OBTAIN FREQUENCIES WILL BE FULLY AUTOMATIC BUT WITH PROVISION FOR MANUAL OVERRIDE/MODIFICATION. ANALYSIS WILL BE PERFORMED TO DETERMINE THE FEASABILITY OF IMPLEMENTING THE OPTIMUM PROCEDURES IN A COMPACT ...

IN MODERN WARFIGHTING THEORY, A COMMAND, CONTROL, COMMUNICATIONS AND COUNTERMEASURES (C3CM) STRATEGY SOULD BE USED TO EMPLOU OPERATIONS SECURITY, DECEPTION (EXPLOITATION), JAMMING AND DESTRUCTIVE MEANS AGAINST AN ADVERSARY. A CREDITABLE CONCEPT ON HOW TO MEASURE THE WARFIGHTING BENEFITS OF A COMPREHENSIVE C3CM STRATEGY IS NEEDED. THE INCORPORATION OF SUCH A CONCEPT INTO AN EXISITING DECISION AID T ...
