RESEARCH AND DEVELOPMENT WILL BE CARRIED OUT TO PROVIDE PROTOTYPE, ACTIVELY CONTROLLED GAS BEARINGS FOR PRECISION MOVEMENT IN INSTRUMENTS AND MACHINE TOOLS. THIS WILL DRAW UPON PRELIMINARY WORK ON (1) FABRICATION, (2) DYNAMIC ANALYSIS OF THE BEARING AND SUPPORTED MASS, (3) PIEZOELECTRIC VALVING AND PIEZOELECTRIC DISPLACEMENT OF THE BEARING SURFACE, AND (4) THE ADAPTATION OF A MICROPROCESSOR TO SER ...

INCREASINGLY SMALLER SPACE AND TIME SCALES AND ELECTROMAGNETIC CONTAMINATION HAVE BECOME BARRIERS RECENTLY IN SOME AREAS OF OCEANOGRAPHIC MEASUREMENT; THE NEED FOR AN INDEX OF REFRACTION SENSOR IS EMERGING, ALONG WITH THE TECHNICAL CAPABILITY TO PRODUCE IT. THIS PROPOSAL SEEKS TO DEVELOP A TECHNIQUE BY WHICH THE INDEX OF REFRACTION OF SEA WATER MODULATES THE WAVE LENGTH BANDWIDTH OF A CW OPTICAL S ...

AN EFFORT TO DEMONSTRATE AN ALL DIELECTRIC OPTICAL MAGNETOMETER OF HIGH SENSITIVITY IS PROPOSED. THE CONCEPT IS BASED UPON THE DETECTION OF MAGNETIC FIELD INDUCED BIREFRINGENCE IN A PARAMAGNETIC MATERIAL HAVING A HIGH VERDET CONSTANT. THE PROPOSED SENSOR RELIES ON THE USE OF AN OPTRA DEVELOPED 2-FREQUENCY HELIUM NEON LASER, IN A COHERENT HETERODYNE DETECTION MODE, TO ACHIEVE A PHASE ANGLE RESOLUTI ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

SIMULATION LANGUAGES, SUCH AS GPSS/H, SIMSCRIPT II.5 GASP, ETC. ARE BECOMING INCREASINGLY POPULAR AS THE TOOL IN THE DETAIL DESIGN AND ANALYSIS OF DISCRETE EVENT SYSTEMS, SUCH AS TRANSPORTATION NETWORKS, MANUFACTURING SYSTEMS, COMPUTER/COMMUNICATION NETWORKS. THE BASIC LIMITATION OF SIMULATION IN REAL WORLD APPLICATIONS STUDIES IS TIME AND COST (TIME TO CONSTRUCT AND RUN THE PROGRAM, COST OF EXTEN ...

SITE CHARACTERIZATION, THE PROCESS OF EVALUATING EXISITING SUBSURFACE SOIL AND ROCK CONDITIONS AND THEIR IMPACT ON PROJECT DESIGN AND CONSTRUCTION, IS A COMMON ELEMENT IN EVERY GEOTECHNICAL DESIGN PROJECT. SINCE THE PROCESS IS COMPLICATED BY SPARSE DATA AND THE NEED TO QUANTIFY UNCERTAINTIES, IT IS A NATURAL AREA TO APPLY RISK ANALYSIS AND PROBABILITY THEORY. THE PROPOSED RESEARCH WILL INVOLVE AN ...

Chemical warfare agents (CWAs), such as nerve agents and mustard agents, pose serious threats to our warfighters and civilians. Current formulations of dermal medical countermeasures to CWAs can be absorbed through the skin causing systemic toxicities to the patients. These formulations are limited by the FDA for use only in small area of intact skin. This severely restricts the usefulness of thes ...

The skin is the first line of defense against chemical warfare agents including nerve agents and toxic industrial chemicals, providing a possible barrier or delay to systemic distribution. Some chemicals also can act directly on the skin including the vesicants sulfur mustard and lewisite. Early and rapid skin decontamination is extremely important following exposure to CWAs and TICs because it de ...

Interfaces on existing military chemical/biological protection garments are not designed to fully eliminate macroscopic and microscopic air gaps at folds, fabric surfaces, or hook-and-loop closures, and thus do not provide a hermetic barrier against exposure. Creare is developing hermetic garment closure systems that seal macroscopic and microscopic gaps at interfaces and closures and provide high ...

Effective collective protection fabrics must have a reliable closure system. During our Phase I Work Plan, Sigma-K began developing a Hermetic Textile Closure Hardware (HATCH) system. The HATCH combines both a magnetic and geometric self locking mechanism that will provide a hermetic seal when closed. Our current Phase I successes include developing self closing samples that can provide a hermetic ...
