THIS PROJECT INVESTIGATES A CONCEPT FOR A CONTINUOUS REFRIGERATOR FOR OPERATION IN ZERO-GRAVITY WHILE COOLING SENSORS TO A TEMPERATURE DOWN TO 0.3 KELVIN. NO CAPABILITY SUCH AS THIS CURRENTLY EXISTS. THE CONCEPT ASSUMES A SUPERFLUID HELIUM DEWAR (1.5 KELVIN) AS THE HIGH-TEMPERATUREHEAT SINK. A SUPERFLUID HELIUM-4 STAGE, CALLED A "VORTEX" REFRIGERATOR, SERVES AS AN INTERMEDIATE COOLING SYSTEM TO IN ...

TAC PROPOSES TO CONDUCT A STUDY TO EVALUATE THE COMPARATIVE EFFECTIVENESS OF VARIOUS FORWARD-LOOKING AUTONOMOUS SENSORS AND ALGORITHMS FOR TLAM-C. THE CURRENT TLAM-C USES A TERRAIN MAPPING RADAR ALTIMETER AND CORRELATES THE SENSED AREA AT KEY WAYPOINTS WITH A STORED DIGITAL REPRESENTATION OF THE TERRAIN AREA AT THE WAYPOINTS TO PROVIDE MID-COURSE AND TERMINAL GUIDANCE CORRECTION TO THE INERTIAL NA ...

THE OBJECTIVE OF THIS DEVELOPMENTAL EFFORT IS TO DETERMINE THE FEASIBILITY OF DEVELOPING A COMPUTER INTEGRATED ROBOT WORK CELL GAGING FINISHED PARTS OR OTHER ASSEMBLY/MACHINING OPERATIONS. THE FOCUS OF THE RESEARCH IS TO CONTROL THE ROBOT TOOL CONTROL POINT (TCP) THROUGH AN ADAPTIVE FEEDBACK CONTROL SYSTEM. THE ROLE OF THE FEEDBACK CONTROL SYSTEM IS TO CONTROL AND MODIFY THE PATH OF THE TCP TO WIT ...

THE OBJECTIVE OF THIS DEVELOPMENT IS TO DETERMINE THE TECHNICAL FEASIBILITY OF DEVELOPING A THREE DIMENSIONAL VISION BASED PASSIVE OBJECT RECOGNITION SYSTEM CAPABLE OF GENERATING THREE DIMENSIONAL COORDINATE LOCATION INFORMATION IN REAL TIME AT VIDEO FRAME RATES OF 30 FRAMES PER SECOND. THE SYSTEM CONFIGURATION UNDER INVESTIGATION WILL UTILIZE PARALLEL PROCESSING OF RAW VIDEO INPUT FROM MULTIPLE C ...

THIS PROJECT ADDRESSES DEVELOPMENT OF ADVANCED COMPUTATIONALTECHNIQUES FOR ANALYSIS OF TRANSIENT AND THREE-DIMENSIONAL EFFECTS WITHIN ROCKET ENGINES. THE COMPUTATIONAL EFFICIENCYOF THESE NUMERICAL ANALOGS ALLOWS CALCULATION OF THE COMPLEXFLOWS WHICH ACCOMPANY THE TRANSIENT OPERATION OF REAL ENGINES. SINCE THE STABILITY AND ACCURACY CHARACTERISTICS OF THE ANALOGS DO NOT REQUIRE EXCESSIVE NUMBERS OF ...

THIS PROJECT APPLIES SEVERAL INNOVATIVE CONCEPTS FOR MODIFYING AN EXISTING AIRBORNE MULTISPECTRAL SCANNER TO MAKEIT CAPABLE OF MEASURING OCEAN BIOMASS IN SUPPORT OF THE NASAGLOBAL BIOLOGY EFFORT. PROVEN FEASIBILITY OF THIS APPROACH WOULD PERMIT ACCOMPLISHMENT OF NASA OBJECTIVES WITHOUT THE NEED FOR AN EXPENSIVE AND LONG-TERM DEVELOPMENT PROGRAM. THE RESEARCH INCLUDES THE ANALYSIS OF EACH OF THE SP ...

ATOMIC IODINE IS USED SUCCESSFULLY AS THE ACTIVE ELEMENT IN HIGH POWER LASERS OPERATING AT 1.3 MICRON WAVELENGTH. THE IODINE LASER TRANSITION IS EFFICIENTLY PUMPED BY MOLECULAR OXYGEN IN ITS SINGLET DELTA EXCITED STATE. THE OBJECTIVE OFTHIS RESEARCH IS TO INVESTIGATE AND EVALUATE A METHOD FOR GENERATING SINGLET OXYGEN (02) GAS DIRECTLY FROM SOLID-PHASEMATERIAL, AND TO RELATE THE INFORMATION OBTAIN ...
