Imaging with X-rays and gamma rays is a long established technique. It is possible with recent technological advances that standard transmission radiography may be extended to self-radiography, where the natural radioactivity of the object itself and the surrounding matrix is used as the source of X-rays. Self-radiography is much more complex than traditional radiography, chiefly because it depend ...

Simulation techniques play an important role in material and device design at the nanoscale. Among these techniques, molecular dynamics (MD) simulation has become a powerful tool for revealing complex physical phenomena. However, completely modeling nano-structured materials and nano-devices of tangible size using MD simulation is unrealistic, even when using today’s most powerful supercomputers ...

The first sentinel of ABL’s present target acquisition suite is a passive infrared search and track sensor of 1970s vintage, which we propose replacing with HyPAWS. HyPAWS is a low-cost passive wide-field of view staring sensor. Several such units suffice to provide full 360-degree view coverage. Leveraging revolutionary sensing techniques in ongoing development, HyPAWS offers advanced detect ...

Physical Sciences Inc. proposes an innovative approach to rapidly concentrate (1000:1) bacterial spores from large volumes of water for identification. The technique is based on acoustophoresis – the separation of particles with sound. Since the technology has already been demonstrated on a small scale our primary focus is on scalability for large volumes (1000 L) in short periods of time (10 mi ...

Hydrometeor impact/erosion qualification evaluations of aerospace vehicle components have to relate testing carried out in ground test facilities to what the components experience in the flight environment. The size distribution and condition of the hydrometeors that impact the surface of a radome can differ substantially from what they are in the natural environment before encountering a missile ...

Epitaxial Technologies' overall objective is to develop innovative detector technologies that can be used to produce enhanced quantum efficiency and high detectivity VLWIR sensors that can operate at high temperatures. The goal of Phase I will be to investigate dilute nitride strain layer superlattice material structures that are capable of enhanced gain and detectivity and then grow and fabricate ...

It is proposed to investigate an innovative mitigation technique for insensitive munitions through a new rocket motor case design. The proposed study will focus upon developing a motor case with sympathetic responses to unplanned thermal stimuli. This particular motor case design will be according to current operating mission parameters for a specific MDA rocket booster.

This Phase-I STTR MDA Proposal proposes the use of a new class of diamond-seeded solid-state material system for the manufacture of virtually all heat-generating solid-state electronics in X-band and Ballistic Missile Defense radar components and systems. In this proposal wherein much preliminary (DARPA- and MDA-funded) work has been demonstrated hitherto by the authors, all or most of the basic s ...

Durability is the effect of time dependant processes, including fatigue, creep, moisture absorption, thermal-oxidation, abrasion, chemical reactions and physical ageing on mechanical properties. The ability to predict accurately the durability of composite materials and structures is critical to successfully designing for longevity. The existence of models alone is not sufficient; practical soft ...

OPTRA is proposing the development of a 3D cloud profiling system that combines an innovative Imaging Open Path Fourier Transform Infrared Spectrometer (I-OPFTIR) with advanced computational tomography algorithms. The proposed technology expands the capability of OP-FTIR systems to 3D profiling applications. It does this by adding a spatially dispersed array of sensors at the focal plane of a si ...
