The Award database is continually updated throughout the year. As a result, data for the given year is not complete until April of the following year. Annual Reports data is a snapshot of agency reported information for that year and hence might look different from the live data in the Awards Information charts.

  1. MAGNETIC DIPOLE RADIATION GENERATED IN AN UNDERGROUND NUCLEAR EXPLOSION: A METHOD FOR MEASURING YIELD

    SBC: Amparo Corp.on            Topic: N/A

    BOTH ATMOSPHERIC AND HIGH-ALTITUDE NUCLEAR EXPLOSIONS WILL PRODUCE MAGNETIC SIGNALS THAT ARE DETECTABLE OVER VERY LARGE DISTANCE. AN UNDERGROUND EXPLOSION WILL ALSO PRODUCE A MAGNETIC SIGNAL, BUT IT IS DETECTABLE AT MUCH SMALLER DISTANCE. THIS IS BECAUSE THE UNDERGROUND FIREBALL IS INERTIALLY TAMPED BY THE MORE DENSE EARTH, AND BECAUSE THE LOW FREQUENCY ELECTROMAGNETIC WAVE IS STRONGLY ATTENUATED ...

  2. DECOUPLED PENETRATION ANALYSIS

    SBC: Applied Research Associates, Inc.            Topic: N/A

    THE OBJECTIVE OF THE EFFORT IS TO DEMONSTRATE THAT A DECOUPLED FINITE ELEMENT ANALYSIS OF A PENETRATION EXENT INTO CONCRETE CAN BE USED AS A COST EFFECTIVE EVALUATION TOOL TO ASSIST THE WEAPON DEVELOPER. A PENETRATION CODE SUCH AS SAMPLL OR THE PENCO-3D MODULE OF EVA-3D WILL BE USED TO DETERMINE THE LOADS ON THE PENETRATOR. THE LOADS THEN WILL BE APPLIED TO THE FINITE ELEMENT MESH AND THE RESPONSE ...

  3. RESEARCH AND DEVELOPMENT OF AN OPTIMUM DEVICE TO REDUCE SEISMIC STRUCTURAL POUNDING DAMAGE

    SBC: Applied Research Associates, Inc.            Topic: N/A

    DURING THE 1989 LOMA PRIETA EARTHQUAKE, IMPACT OF ADJACENT BUILDINGS, KNOWN AS POUNDING, CONTRIBUTED TO DAMAGE IN SEVERAL HUNDRED STRUCTURES IN THE SAN FRANCISCO BAY AREA. IN ADDITION, DURING THE 1985 MEXICO EARTHQUAKE, POUNDING WASIDENTIFIED AS PRESENT IN OVER 40% OF COLLAPSED OR SERIOUSLY DAMAGED BUILDINGS AND WAS IDENTIFIED AS BEING RESPONSIBLE FOR 15% OF THE COLLAPSES. IN FACT, EXAMPLES OF BUI ...

  4. AIR BLAST RESPONSE OF LOW DRAG SHAPE LAUNCHER VEHICLES

    SBC: Applied Research Associates, Inc.            Topic: N/A

    THE PROPOSED RESEARCH ADDRESSES METHODS OF INCREASING THE BLAST HARDNESS OF MOBILE LAUNCH VEHICLES BY THE REDUCTION OF THE DRAG AND LIFT DURING THE DRAG PHASE OF BLAST LOADING. THE WORK WILL DEVELOP MOBILE LAUNCH VEHICLE SECTION PROFILES WHICH REDUCE THE DRAG AND LIFT COEFFICIENTS WITHOUT INCREASING THE DIFFRACTION PHASE BLAST LOADS. THE PROFILES WILL BE DEVELOPED BASED ON EXISTING KNOWLEDGE GLEAN ...

  8. ROBUST AND FAST NUMERICAL GRID GENERATION

    SBC: Ecodynamics Research Associate            Topic: N/A

    NUMERICAL GRID-GENERATION ALGORITHMS ARE BECOMING MORE CRITICAL DUE TO THE NEED FOR DETAILED MODELING OF THE GEOMETRY OF THE PHYSICAL DOMAIN AND AS PART OF SOLUTION-ADAPTIVE ALGORITHMS. CURRENT PLANAR GRID GENERATION ALGORITHMS ARE NOT ROBUST BECAUSE THEY FREQUENTLY PRODUCE SKEWED OR FOLDED GRIDS. THESE PROBLEMS CAN BE CORRECTED BY TRIAL AND ERROR MODIFICATIONS (E.G., TO THE SOURCE TERM OF A POISS ...

  9. LOW MAINTENANCE DOOR CLOSURE

    SBC: Electro Magnetic            Topic: N/A

    WE HOPE TO INVESTIGATE THE POTENTIAL USE OF AN ELECTROMAGNETIC DOOR SEAL AS A COMPONENT IN A LOW MAINTENANCE DOOR CLOSURE. THIS SEAL WILL INSERT A LOSSY FERROMAGNETIC MATERIAL INTO THE PATH BY WHICH ELECTROMAGNETIC ENERGY ENTERS A SHIELDED ENCLOSURE AROUND THE PERIPHERY OF THE DOOR. THE MATERIAL IS EXPECTED TO REFLECT THE INCIDENT FIELD BECAUSE THE FERROMAGNETIC MATERIAL WILL OFFER A HIGH IMPEDANC ...

  10. ELECTROMAGNETIC PULSE (EMP) COUPLING TO CABLES

    SBC: Electro Magnetic            Topic: N/A

    A COMBINED ANALYSIS AND EXPERIMENT PROGRAM IS PROPOSED THAT WILL IMPROVE THE ACCURACY OF THE REVISED TRANSMISSION LINE MODEL FOR A CABLE NEAR OR ON THE SURFACE OF A LOSSY EARTH. ANALYSIS WILL BE USED TO DETERMINE THE EFFECTS OF FREQUENCY DEPENDANT EARTH PARAMETERS ON THE MODELED IMPEDANCE. EXPERIMENTS WILL BE CONDUCTED UNDER CONTROLLED CONDITIONS TO VERIFY THE PREDICTIONS OF THE REVISED TRANSMISSI ...
