MERCURY IS A HIGHLY TOXIC MATERIAL THAT OCCURS IN BOTH ORGANIC AND INORGANIC FORMS. BECAUSE OF ITS WIDESPREAD INDUSTRIAL USE THE WHOLE POPULATION IS EXPOSED TO MERCURY COMPOUNDS EVERYDAY. THERE IS A NEED FOR A FAST, EASY TO USE, INEXPENSIVE, SENSITIVE METHOD FOR THE DETECTION OF MERCURY TO REDUCE THE RISK OF CHRONIC EXPOSURE. OUR OBJECTIVE IS TO DEVELOP A NEW TECHNIQUE FOR THE SELECTIVE DETECTION ...

THE DEPARTMENT OF DEFENSE HAS IDENTIFIED THE INCREASING LIKELIHOOD OF COMBAT IN URBAN ENVIRONMENTS. RECENT YEARS ARE RICH WITH EXAMPLES OF THE MILITARY'S NEED TO PERFORM SUCCESSFULLY IN BUILT-UP AREAS. THE LOGISTICS REQUIREMENTS UNIQUE TO A MILITARY OPERATION IN AN URBAN AREA CALL FOR CAREFUL PLANNING AND WELL TRAINED, WELL REHEARSED FORCES. CREATING A THREE-DIMENSIONAL MODEL OF THE AREA OF INTERE ...

HIGH FREQUENCY (HF) RADIO HAS HISTORICALLY BEEN AND WILL CONTINUE TO BE A VITAL MEDIUM FOR COMMUNICATIONS CAPABLE OF OPERATION WITHOUT RELAY TO OVER-THE-HORIZON DISTANCES USING RELATIVELY INEXPENSIVE EQUIPMENT. LOCATION AND TRACKING OF COMMUNICATION SIGNALS CAN PROVIDE A VALUABLE SOURCE OF EXTRACT ANGLE OF ARRIVAL INFORMATION IN THE PRESENCE OF SEVERE IONOSPHERIC PROPAGATION EFFECTS. WE PROPOSE TO ...

THERE IS A MAJOR ARMY REQUIREMENT FOR REDUCING THE PHYSICAL SIZE OF TACTICAL HF ANTENNAS (FOR USE ON A VARIETY OF CARRIERS FROM TRACKED VEHICLES TO DRONES) FOR ELECTRONIC WARFARE APPLICATIONS WITHOUT DEGRADING CURRENTLY ACCEPTED PERFORMANCE AND STILL MAINTAINING THE SAME GAIN, FREQUENCY AND POWER HANDLING CAPABILITIES. THE APPROACHES WHICH ARE POTENTIALLY CAPABLE OF ACHIEVING THIS ARE: SUPERCONDUC ...

TACTICAL DECISION AIDS, TDA, SYSTEMS ARE UTILIZED BY THE BATTLEFIELD COMMANDER IN A DYNAMIC, INFORMATION FILLED ENVIRONMENT. WITH THE CONTINUING INCREASE IN DATA AND INFORMATION AVAILABLE, AND WITH THE CONTINUING SHORTAGE OF EXPERT PERSONNEL, THE CRITICAL REQUIREMENTS OF FUTURE TDA SYSTEMS ARE FOR SPEED AND MORE AUTONOMOUS PROCESSING. THIS PROPOSAL PRESENTS A SOUND ENGINEERING APPROACH FOR DERIVIN ...

THE RECENT DEVELOPMENT OF HIGH-POWER GAALAS DIODE LASER ARRAYS EMITTING IN THE 740-890 UM REGION ENCOURAGES THE SEARCH FOR NEW CHROMIUM-DOPED CRYSTALS FOR NEAR-INFRARED TUNABLE LASERS WITH POTENTIAL FOR IMPROVED PERFORMANCE. AMONG THE MANY CRYSTAL HOSTS, THERE ARE THOSE WITH STRUCTURE POSSESSING DISTORTED OCTAHEDRAL SITES WITH APPROPRIATE SYMMETRIES FOR THE PRODUCTION OF LEVEL SPLITTING AND LARGE ...

POTENTIAL ADVERSARIES USING COMMERCIALLY-AVAILABLE, SPACE SURVEILLANCE SYSTEMS CAN POSSIBLY CIRCUMVENT OTHERWISE EFFECTIVE FORCE MANAGEMENT ACTIVITIES. AN EVALUATION OF SUCH SPACE SYSTEMS IS PROPOSED, ALONG WITH DEVELOPMENT OF A MEANS TO EQUIP COMMANDERS WITH THE READY CAPABILITY TO EFFECTIVELY COUNTER SUCH SYSTEMS. THE PROPOSED STUDY LOOKS AT THE TECHNICAL CAPABILITIES AND OPERATIONS OF NON-MILIT ...

THE INABILITY TO DETECT TOXINS WITH ADEQUATE SENSITIVITY IS ONE OF THE PRINCIPAL REASONS THAT THEY ARE POTENTIALLY THREATENING, EITHER DUE TO "NATURAL" EXPOSURE OR DELIBERATE AND HOSTILE USE OF THESE AGENTS BY AN ADVERSARY. THIS PROPOSAL OUTLINES A WAY THAT THE DETECTION OF THESE TOXINS CAN BE MADE MUCH MORE SENSITIVE WITHOUT USE OF EXPENSIVE EQUIPMENT OR HIGHLY TRAINED PERSONNEL FOR THE FINAL PRO ...

MOLTEN SALT LITHIUM BATTERIES OFFER THE PROSPECT OF VERY HIGH PULSE POWER DENSITIES COUPLED WITH HIGH SPECIFIC ENERGY DENSITIES. FOR PULSE POWER APPLICATION, U.S. ARMY REQUIRES PROJECTED CURRENT DENSITIES OF HUNDREDS OF AMPERES PER SQ.CM. IN THE MILLISECOND RANGE AND TENS OF AMPERES PER SQ.CM. IN THE FRACTIONS OF SECOND. CATHODES FOR SUCH MOLTEN-SALT LITHIUM BATTERIES MUST HAVE HIGH THEORETICAL EN ...

THE PRIMARY OBJECTIVE OF THIS PROPOSED EFFORT IS TO DEVELOP A PROTOTYPE IMAGE VIEWING SYSTEM THAT CAN RECOVER, DUPLICATE AND DISPLAY ARCHIVED X-RAY IMAGERY AND ANALYSIS DATA OF MUNITIONS ITEMS. THE SYSTEM IS DESIGNED TO BE EXTENSIBLE SO THAT IN THE PHASE II EFFORT AN IMAGE ANALYSIS OPTION CAN BE EASILY INTEGRATED INTO THE OVERALL SYSTEM. THE IMAGE ANALYSIS OPTION WILL BE DESIGNED TO SIMULATE THE A ...
