TWO LOCAL AREA NETWORK (LAN) STANDARDS, IEEE 802.5 AND ANSI X3T9.5 FFDDI, HAVE SEEN INCREASED USE AMONG BOTH MILITARY AND INDUSTRIAL USERS ESPECIALLY FOR APPLICATIONS WHICH HAVE TIME-CRITICAL PERFORMANCE REQUIREMENTS. THESE STANDARDS ARE THE BASIS OF PROPOSED NAVY STANDARDS, DESIGNATED SAFENET-I AND SAFENET-II. IN THE EVENT OF A FAILURE, A KEY PERFORMANCE PARAMETER ESSENTIAL TO DESIGNERS OF TIME-C ...

WITH CURRENT FDA-APPROVED PROTOCOLS FOR THE CRYOPRESERVATION OF HUMAN RED BLOOD CELLS, THE CELLS ARE TREATED WITH MULTIMOLAR CONCENTRATIONS OF GLYCEROL, A PERMEATING CRYOPROTECTANT. AFTER THAWING, EXTENSIVE PROCESSING OF RED CELLS IS REQUIRED TO REMOVE THE GLYCEROL, PRIOR TO TRANSFUSION, TO PREVENT HEMOLYSIS. FURTHERMORE, EVEN IN THE PRESENCE OF CRYOPROTECTANTS, THE FORMATION OF ICE DURING COOLING ...

THE PROPOSED WORK AIMS TO DEVELOP NOVEL, HIGH PERFORMANCE SPATIAL LIGHT MODULATORS (SLM) MADE FROM ARRAYS OF FERROELECTRIC LIQUID CRYSTAL (FLC) LIGHT VALVES. THE FLC TECHNOLOGY ALLOWS SIMPLE, ECONOMICAL FABRICATION OF SLMS WITH A LARGE NUMBER OF ELEMENTS THAT CAN BE EASILY ADDRESSED EITHER ELECTRONICALLY OR OPTICALLY. PERFORMANCE FEATURES INCLUDE SUBMICROSECOND WRITE TIMES, HIGH OPTICAL THROUGHPUT ...

THE PROPOSED PROJECT AIMS TO DEVELOP A 1 X 2 ELECTRO-OPTIC SWITCH FOR USE WITH MULTIMODE OPTICAL FIBERS. BY EMPLOYING LIGHT VALVES HAVING FERROELECTRIC LIQUID CRYSTALS AS THE ELECTRO-OPTIC MEDIUM, THE DEVICES TO BE DEVELOPED WOULD EXHIBIT SWITCHING TIMES AT OR BELOW 1 MICROSECOND. THE DEVICES WOULD BE SMALL IN SIZE, CONSUME LITTLE ELECTRICAL POWER AND WOULD COMPLETELY SWITCH UNPOLARIZED LIGHT WHIL ...

THE PROPOSED WORK AIMS TO DEVELOP A MULTICOLOR FLAT PANEL INFORMATION DISPLAY BY COMBINING A MONOCHROME, HIGH-INFORMATION-CONTENT PANEL WITH AN ELECTRICALLY TUNABLE COLOR FILTER. MULTICOLOR IMAGES ARE PRESENTED BY SEQUENTIALLY PRESENTING MONOCHROME IMAGES IN THE THREE PRIMARY COLORS WHILE SIMULTANEOUSLY TUNING THE FILTER FOR THE CORRECT ILLUMINATION COLOR. WE PROPOSE TO MAKE NOVEL TUNABLE COLOR FI ...

THIS PROPOSAL DESCRIBES A NOVEL PROCESSING TECHNOLOGY WHICH HAS THE POTENTIAL TO ACCELERATE THE DEVELOPMENT OF NICKEL ALUMINIDE COMPOUNDS INTO MATURE MATERIALS FOR ADVANCED APPLICATIONS. THIS TECHNOLOGY COMPRISES A CONTINUOUS, TWO PHASE PROCESS IN WHICH CLOSED POROSITY NICKEL ALUMINIDE BODIES ARE FIRST FABRICATED BY EXOTHERMALLY-DRIVEN SELF PROPAGATING COMBUSTION SYNTHESIS FROM ELEMENTAL POWDER BL ...

BOND ENERGIES, OR ENTHALPIES, WILL BE DETERMINED FOR SEVERAL SUBSETS OF HIGH ENERGY-DENSITY COMPOUNDS WHICH CONTAIN ONLY THE ELEMENTS BORON, NITROGEN, PHOSPHORUS, FLUORINE, OXYGEN AND HYDROGEN. THE METHODS USED WILL BE THOSE OF THERMOCHEMISTRY, SPECTROSCOPY, AND QUANTUM MECHANICAL CALCULATIONS OF VARYING LEVELS OF SOPHISTICATION, DEPENDING UPON MOLECULAR COMPLEXITY. THE THREE SUBSETS OF COMPOUNDS ...
