21st Century Systems, Inc. proposes to research and realize agent-based decision support system under uncertainty for submarineoperations. We will use a highly innovative hybridBayesian/differential game modeling approach to tackle thisproblem. The resulting theory and technology will facilitatesubmarine options by addressing such practical problems astradeoff evaluation for course of action and ...

For efficient space operations, and for effective space force enhancement to terrestrial forces, Aerospace Operations Center (AOC) personnel must be continuously aware of the status of on-orbit assets, payload coverage, reacting to system degradations andfailures, and responding to intolerant environments for satellites. To complete the situational awareness picture, there is also the need to depi ...

The overall goal of the proposed research is to develop a comprehensive, efficient, and well validated model of various remelting processes used for the production of ingots of superalloys and titanium alloys. Phase I research has demonstrated thefeasibility and the validity of developing a unified computational model for efficient and accurate prediction of AC and DC electromagnetics, fluid flow, ...

This Small Business Innovation Research Phase II project,

Spin-dependent-tunneling (SDT) sensors are emerging as a microelectronics-based magnetic-sensor technology for the broadband detection of low-level fields produced by objects such as military or commercial vehicles. The sensors offer the potential of smallsize, low cost, low power, and low-field resolution. The sensitivity of the devices is high, however they exhibit a significant

NVE will produce and package IC's that monolithically integrate high speed GMR signal isolators into prototype high-speed 74245 type transceivers and 74573 type logic latches. Commercial high-speed data bus interfaces between microcontroller basedsubsystems have not been galvanically isolated due to performance, size and cost constraints. These interfaces would benefit from the inclusion of mono ...

It is proposed to use spin dependent tunneling (SDT) and giant magnetoresistance (GMR) magnetic sensors and eddy current techniques for Non-Destructive Inspection (NDI) to detect flaws in various metallic components including cracks around rivet holes andfailed bonds in diffusion bonded components. This Phase II proposal is directed towards designing, optimizing, manufacturing, and demonstrating s ...

This project focuses on incorporating features to enable VPN operation in the presence of Network Address Translation (NAT) devices, and improved management of remote access, Intranet and Extranet VPNs. In addition, capabilities to accelerate VPN trafficat both VPN clients and VPN gateways will be developed. To support this, the project will define an approach to monitoring the performance of VP ...

GaInSb/InAs superlattices show great promise as materials for use in very long wavelength infrared (VLWIR) detectors. This III-V compound offers advantages over current HgCdTe technology in both anticipated performance level and ancillary support system(e.g. cryogenic cooling) costs. Due to its piezoelectric characteristic, (111)-oriented superlattice lowers the effective bandgap energy when com ...
