Perchlorate is a widely used component of solid fuel, missile and rocket propellants, explosives, and pyrotechnics. It has been shown to reduce iodide uptake into the thyroid gland. The U.S. Environmental Protection Agency (EPA) has found perchlorate contamination in 18 states and believes contamination may exist in as many as 39 states. In early January 2005, the National Academy of Science ...

Lead in household paint and dust is a serious health hazard, as low-level lead exposure can result in a number of adverse health effects, especially in children. Onsite and real-time detection and quantification of lead in paint/dust are very important to homeowners and certified lead-based paint removal professionals. Toward this end, both field-portable equipment (such as X-ray fluorescenc ...

ABARIS PROPOSES AN EXPERT SYSTEM TO AID THE AVIATION PLANNER AND COST ESTIMATOR IN DEALING WITH THE IMPACT OF NEW MATERIALS AND TECHNOLOGY AVAILABLE FOR THE DESIGN AND SUBSEQUENT MANUFACTURE OF NEW AIRCRAFT. THE NEW ADVANCED COMPOSITES; GRAPHITE AND KEVLAR FIBERS, EPOXY AND BISMALEIMIDE RESINS, ETC., OFFER SIGNIFICANT WEIGHT REDUCTIONS AND OTHER OPERATIONAL ADVANTAGES, BUT REQUIRE DIFFERENT DESIGN ...

This proposal addresses the development and use of lightweight, low thermal-capacity reformable tooling materials for high-temperature composite processing evaluation, parts prototyping, trial production and full-rate production of PMC engine components. The weight-saving promise of high-temperature polymer matrix composites (PMCs) for engine components is offset by the very high costs of parts m ...

Extending gun barrel life has been a long-standing goal for the US Air Force and other DoD agencies. Currently-used chrome plated barrels are susceptible to erosion and corrosion which affects the accuracy of fired bullets due to material loss along the inner surface. The primary cause of barrel degradation is the poor quality chrome coating and attack of steel inner surface by hot gases and comb ...

The rapid increase in the use of the Internet in many aspects of our lives has led to an explosive growth in the spread of malware such as computer worms, viruses, and trojans. Security tools typically examine software for the presence of malware either by looking for specific byte signatures, or (more recently) by analyzing the candidate binary’s internal logic. However, it is surprisingly easy ...

We propose to examine the necessary ingredients for the development of marketable codes which will: model the morphology of heterogeneous propellants (a packing code); calculate the thermal and mechancial properties of such a morphology or pack; simulate the combustion of the pack; predict the statistics of aluminum agglomeration on the burning pack surface; simulate the flight of these agglomera ...

In Phase I, we propose to develop novel electromagnetic software that can model the complex requirements of modern electronically scanned array (ESA). We will focus on fast algorithms for rapid analyses of ESA using parallel computers, allowing the efficient analyses of multimode character of an ESA. The efficient algorithm will be achieved by using thin-dielectric sheet for perfect electric c ...

DUE TO RISING COSTS OF ALUMINUM, MILITARY CONTAINERS USING ALUMINUM EXTRUSIONS WILL BE STUDIED TO DETERMINE IF PLASTICS CAN ACHIEVE A COST AND WEIGHT EFFECTIVE REPLACEMENT OF TYPICAL PROFILES. BOTH THERMOPLASTICS (TP) AND THEMOSETS (TS) CAN BE MADE TO THE SAME PROFILES AS ALUMINUM EXTRUSIONS, BUT PERFORMANCE OF THE PROFILE WILL BE QUESTIONABLE. REINFORCEMENTS CAN BE ADDED IN THE FORM OF PARTICULAT ...

CONCEPT ANALYSIS CORPORATION (CAC) PROPOSES TO DETERMINE THE FEASIBILITY OF FABRICATING SELF DEPLOYING SPACE STRUCTURES WHICH DO NOT USE ACTUATORS. IN PHASE I, CAC WILL EVALUATE THE CHARACTERISTICS OF THE PLASTIC MEMORY PHENOMENA WHICH COULD BE USED AS A SELF DEPLOYING MECHANISM. PHASE II IS ENVISIONED FOR DEVELOPMENT AND FULL SCALE TESTING. PLASTIC MEMORY IS RECOGNIZED AS THE TENDANCY OF A STRUCT ...
