The objective of the this phase 1 proposal is to design and develop an access control policy framework that is a scaleable across the Army enterprise by allowing for the decentralized management and local enforcement of the access control policies, minimize impact on the network with respect to policy traffic, allow for interoperability between Community of Interests (COIs) or domains and allow fo ...

Maintenance on Army Tactical Power Systems (TPS's) is currently performed at regular intervals regardless of actual usage or operating conditions - wasting resources servicing systems that do not need maintenance, and missing opportunities to prevent catastrophic failures. The Army seeks to 1) improve maintenance efficiency and effectiveness by servicing systems based on actual usage and 2) imple ...

The proposed effort will focus on the disruption of networks versus particular communications links using powerful optimization and co-design approaches. A technique for assigning target value metrics will be developed an applied to `best effort' extractions of adversary network topologies proposed in this work. Adversary network usage denial is conducted in conjunction with goals that reflect min ...

Silicon carbide (SiC)semiconductors offer revolutionary improvements in power electronics due to much lower conduction and switching losses, higher switching frequencies, higher voltage capability, higher operating temperatures and other superior properties relative to standard silicon. Losses in a converter will be decreased by a factor of ten, frequency will be increased by a factor of ten and ...

PERFECT VIEW INC. AND THE PRINCIPAL INVESTIGATOR, DR. A. J. ATTAR, HAVE RECENTLY OBTAINED A PATENT ON A METHOD TO REMOVE MINERAL WATER FROM COAL BY FIRST TURNING ITS SURFACE HYDROPHOBIC (U.S. PATENT 4,597,769, ISSUED JULY 1ST, 1986). THE TREATMENT INVOLVES A VERY LOW-COST CHEMICAL REACTION WHICH CONVERTS THE HYDROXLIC AND CARBOXYLIC SURFACE FUNCTIONALITIES TO ETHERS AND ESTERS. THIS TREATMENT REDU ...

THE DESIGN OF PIN DIODE HAVE TRADITIONALLY BEEN CONDUCTED USING LINEARCIRCUIT ANALYSIS AND INVOLVED INCORPORATING OF THE DIODE INTO A LOW PASS STRUCTURE. THIS STUDY WILL IMPLEMENT THE COMPLETE PIN DIODE MODEL INTO THE SPICE SOURCE CODE AND WILL MAKE POSSIBLE THE LINEAR AND NON LINEAR ANALYSIS IN THE TIME DOMAIN AND FREQUENCY DOMAIN. IN THE TRANSIENT ANALYSIS THE SPIKE LEAKAGE AND FLAT LEAKAGE WILL ...

Infection in areas of bone injury are a serious consideration in the field of trauma surgery and orthopaedic medicine. The combination of regenerative medicine and controlled drug delivery offers great potential to improve on the current standard of care. Presently, bone infection secondary to osteomyelitis and non-union are treated in a two-stage protocol wherein the first step requires placeme ...

JAMMER POWER MANAGEMENT REQUIRES SIGNIFICANT EXPERTISE COVERING THE RECOGNITION OF OPPORTUNITIES, AND KNOWLEDGE OF EW SYSTEM CAPABILITIES SYSTEMS TO TAKE ADVANTAGE OF THOSE OPPORTUNITIES. THERE IS DOUBT THAT MANY OF THE FUNCTIONS OF JAMMER POWER MANAGEMENT CAN BE AUTOMATED. FOR EXAMPLE, ELECTROMAGNETIC PATTERN OPTIMIZATION IN THE SPACE, TIME, AND FREQUENCY DOMAINS, PARTICULARLY THE SELECTION OF FR ...
