Graph analytics have emerged as a prominent computational workload in the defense community, and are representative of fundamental kernels in national security applications. Processing speed is a fundamental requirement for these applications. Massively-parallel hardware architectures promise to increase the performance of graph analytics. However, significant improvements in software technologies ...

This SBIR Phase I proposal will investigate a method for measuring magnetic gradients using a pair of cesium vapor cells. The approach involves measuring free-induction decay of atomic polarization based on a method patented by the proposers. By measuring decays in two spatially separate cells, a signal can be extracted which is largely free of magnetic noise from the ambient environment. This sho ...

Antenna-coupled-diode (ACD) detectors are proposed as a method for producing a broadband laser receiver with a 5 GHz electronic bandwidth and NEP less than 1 pW/SQRT(Hz).The ACD detector is an uncooled photon detector that may be operated in either the LWIR or MWIR. Unlike other semiconductor based photon detectors such as HgCdTe, InSb, or QWIP, the ACD detector can be fabricated directly onto Si ...

A compact laser driver will allow photoconductive semiconductor switches to be used in small EMP simulator "building blocks" (EMPBB). Combined with a battery powered on-board pulsed power system, these EMPBBs will allow the construction of flexible EMP test facilities with nothing more than a single fiber optic timing connection to each EMPBB.

The Defense Special Weapons Agency (DSWA) has identified a need to improve the radiation hardness of advanced integrated circuit technologies. To be practical, this must be achieved in a cost effective way. This proposal by AET, Inc. directly addresses these concerns. Specifi-cally, this proposal provides a means to achieve significant advance in radiation hardness of large scale integrated cir ...

The nuclear weapons community has traditionally focused on the next generation or level of weapon capability complimented by gathering and analysis of actual test data. Now, with the cessation of actual weapons testing, there is an increased need to use the actual test data in modeling techniques to better understand the phenomenology and potential effects of nuclear weapons. The first phase of ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...

Engineering Technology, Incorporated (ETI) proposes the design and development of a portable backpack smoke generator for Small Unit Combat, Non-confrontational Combat and National Institute of Justice Applications. The device shall be capable of producing sustained "visible" obscurants, effective in the visible and near-IR wavelengths, but transparent at longer wavelengths. The proposed system ...

The Computationally Intelligent ATR Architecture (CIAA) for SAR imagery will be driven by both point (scatter) and region features. I-MATH has previously developed point extraction algorithms. SAIC will suggest various region measurements, again drawing upon the current results of the MSTAR program. All of the raw features, both point and region associated, including the (x,y) hash point coordi ...

An approach is desired that allows composite infrared background scenes to be synthetically generated using a data base of background objects and types. I-MATH has previously developed an algorithm for a related application, whereby actual scene images are decomposed with a Laplacian pyramid, and then each level in the pyramid is characterized by its second order statistics. Synthetic scene imag ...
