ABSTRACT: The emergence of polymorphic malware poses an increasingly difficult threat to network security. Sentar proposes the development of a Polymorphic Malware Detection Unit that will perform automated detection of dynamically evolving malware as well as zero-day attacks. The Unit will be designed to integrate with existing systems as well as into future systems. Sentar will use predictiv ...

ABSTRACT: The goal of this project is to develop theoretical models for electrode erosion in high-pressure arcs and incorporate them into computational tools for simulations of arc heaters. The complexity of the electrode material removal process is associated with the multi-phase nature of the arc-electrode interactions, melting and vaporization of the electrodes near the arc foot. Available mod ...

ABSTRACT: The overall goal of the proposed effort is to develop and demonstrate a general-purpose, fast, and reliable management and learning software tool for analyzing massive data sets generated by dynamic multi-disciplinary simulations. The salient elements of the software tool are: (1) an innovative combination of Proper Orthogonal Decomposition (POD) and advanced feature detection technique ...

ABSTRACT: This Phase I SBIR will produce a concept, and algorithms, for a Sensor Suite which can be used as a research tool to characterize strong atmospheric turbulence. Previous and on-going theories, statistics, and empirical data will be evaluated to arrive at an optimal Sensor design concept. That Sensor may exploit the superior resolution and performance inherent in the Radio-Hydro-Physi ...

The overall objective of this program is to improve the producibility of HVPE GaN through the use of in-situ monitoring during the growth process. Various in-situ monitoring devices will be used: a UV absorption technique to monitor the GaCl concentration above the growing GaN wafer; a commercial BandiT system capable of measuring optical emission from the growing wafer in order to measure the su ...

Higher efficiency solar cells are needed to reduce mass, volume, and cost of DoD space missions. However, to achieve higher efficiency and radiation hardness of the best to date multi-junction photovoltaic (MJ PV) devices, several challenges must be addressed. This project aims to develop: 1) Quantum Well (QW)-based multi-junction cell technology that exhibits enhanced efficiency, and 2) Radiation ...

The results of the Phase I effort has identified the feasibility of real-time hardbody thermal solver algorithms on high performance hardware for use by MDA applications and real-time hardware-in-the-loop environments. Phase II development of the thermal solver will be expanded to include complex targets by expanding upon the techniques prototyped in Phase I. A new inline Parallel Euler Solver w ...

The MDA is developing the Precision Tracking Space System and other satellite based systems that could benefit from ongoing developments in advanced materials for lithium ion batteries. Unfortunately, the applications driving much of that battery research have less abusive operational cycles than the frequent cycling, and sporadic pulse loads to deep discharge, of MDA satellite applications. Phy ...

ABSTRACT: Our objective is to develop advanced mediator architectures for efficient electron transfer in enzymatic fuel cells (EFCs) for low power systems. The proposed EFC will leverage ongoing research at both CFDRC and Michigan State University to provide a fully-integrated lightweight, low-cost, manufacturable, and renewable power supply, for various military and civilian applications. EFC sy ...

Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. Many other applications including semiconductor processing, cellular-telephone base station transmitters and military communication systems simila ...
