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.

"Aximetric and the Cornell Theory Center (CTC) strongly backed by Microsoft High Performance Computing (HPC) lab proposes a portable parallel computing model for windows platform called Java based Bulk Synchronous Parallel System (JBSP) that is implementedusing the .net clustering technology developed by Microsoft. The uniqueness of this approach is to provide portable model called JBSP.Net using ...

"Thermal control coatings are an important part of any spacecraft. Smaller light weight satellites are especially sensitive to radical changes in their thermal environment as they orbit the earth. An intelligent thermal management system is vital for thesesatellites. This program will develop a new design for an inorganic solid state electrochromic (EC) variable emittance coating with an emittanc ...

"Reflex triode bremsstrahlung sources potentially provide warm X-ray sources (20 keV to 500 keV), capable of generating high doses (~10 cal/g gold) over exposure areas of ~20 cm2. This needed capability allows experimental verification of warm X-ray inducedthermomechanical response, SGEMP, and box IEMP models for achieving component and system certification to hostile environments.In a reflex trio ...

"Nuclear Weapons Effects Tests (NWET) frequently require that the test article be irradiated in an ultra-clean environment, making survivable shields a necessary part of many debris systems. Survivable shields as large as 12 inches in diameter are requiredbut have yet to be demonstrated in Plasma Radiating Source (PRS) environments. The loads on a survivable shield are a combination of radiation i ...

"Measurements of fluence from a Plasma Radiation Source (PRS) are critical to the performance of accurate Nuclear Weapon Effects (NWE) experiments. Fast, total stopping calorimeters have been demonstrated to provide a robust, reusable, economic sensor forfluence measurements. However, the output of these sensors is a few millivolts and thus high signal to noise recording is difficult to achieve, ...

"Advanced military unmanned aero and ground vehicles can benefit from small, lightweight, turbo shaft engines that operate on heavy fuel. Starting with engines that were first developed for use in remote controlled model aircraft and upgrading theirtechnology can produce very capable and affordable engines. This program will upgrade a 10 HP turbo shaft engine (tested in Phase I) to improve its r ...
