ABSTRACT: Neya Systems, LLC is proposing to develop the Unmanned Systems PeRception Evaluation Simulation System (UxPRESS). UxPRESS provides significant opportunities to increase the state of the art for autonomy by tightly coupling the development and e

ABSTRACT: Autonomous vehicles lack a standardized mechanism for seamless cross-platform sharing of testing frameworks and evaluations of basic tasks. The ability to execute common tests on various hardware platforms is essential in order to be able to e

The objective of this proposal is to develop enabling technologies for the production of bulk scintillating nanocomposites that have the gamma radiation detection properties of single crystal NaI but with the manufacturability of plastic scintillators. These performance criteria may be met by developing nanoparticle polymer composites with ultra-high nanoparticle loadings levels in matrix with a h ...

Weidlinger Associates Inc. proposes to develop effective technology for simulating explosive detonations within civil buildings where the propagation of airblast and failure of weak internal walls are strongly coupled. We will conduct a field test program designed to complement other internal detonation testing efforts such as DTRA''s Distinct Cobra, expanding the available database. We will perfo ...

An approach for performing high fidelity modeling for blast and progressive collapse simulations of buildings will be developed. The modeling approach will allow complete simulations of building response to be performed within several days of computing time on desktop PCs. An 'easy to use' modeling interface will also be demonstrated in this effort. All response regimes will be addressed includi ...

For this Phase I SBIR program, high volumetric efficiency, energy storage capacitors are proposed using phase change ceramics. These materials are nonlinear dielectrics that make use of electric field induced antiferroelectric to ferroelectric phase transition to store more energy per volume than is possible with linear dielectrics (10 J/cm3 compared to 2 J/cm3). Furthermore phase change materia ...

On-going developmental programs have produced munitions systems which are capable of penetrating and functioning within hardened fixed ground targets. They are equipped with high explosive and fragmenting warheads to achieve target defeat but in the process produce unaccceptable target venting and agent dispersal. The need exists for a warhead payload which can effectively defeat chemical and bi ...

Low-temperature MBE grown GaAs (LT-GaAs) contains a high concentration of excess As which gives rise to ultra-fast carrier-trapping time and excellent radiation hardness. In as-grown layers most of this excess As is in the form of As(Ga) antisite defects, of which only ~1% are ionized. Thermal annealing upon overgrowth with a device structure or during device processing results in a decrease of ...

ADVANCED STRUCTURAL MATERIALS USED IN THE FABRICATION OF SUBMARINES CAN SUSTAIN LARGE STRAINS DURING THE FORMATION PROCESS CAUSED BY EXPLOSIVE LOADINGS. THE COMPUTATIONAL SOLID MECHANICS COMMUNITY HAS RECENTRLY RECOGNIZED SERIOUS SHORTCOMINGS IN CALCULATIONS USING MATERIAL MODELS IN THIS LARGE STRAIN REGION. BECAUSE OF THE IMPORTANCE OF CALCULATIONS IN UNDERSTANDING THE SHOCK RESPONSE OF SUBMARINE ...
