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 ...

THIS PHASE I EFFORT WILL APPLY THEORETICAL METHODS BASED PRINCIPALLY ON CAGNIARD'S FORMALISM (PREVIOUSLY INCORPORATED BY US INTO OUR POWERFUL SWREF CODE), TO THE PROPAGATION AND FOCUSING, IN BOTH REFLECTIVE AND PHASED-ARRAY EQUIPMENT, OF SHOCK-WAVES PRODUCED BY UNDERWATER SPARKS. THE OBJECTIVE IS TO INVESTIGATE AND PROVIDE DESIGN DATA FOR LITHOTRIPSY EQUIPMENT IN WHICH FOCUSED SHOCK WAVES ARE USED ...

Insuring the safety and control of littoral waters is problematic because of the difficulties of surveillance. The preferred methods of surveillance in the ocean are acoustic. In littoral waters, acoustic methods fail because noise from the surf and reflections from the shallow bottom convolute acoustic signatures beyond our capacity to discern them. Water absorbs light, reducing the effectiven ...

CONVENTIONAL ROCK CORE DRILLING AT GREAT DEPTHS IS EXTREMELY EXPENSIVE AND TIME CONSUMING. ITS MAJOR DRAWBACK IS THE REQUIRED LENGTH OF DRILL PIPE. THE SUSPENSION CORE DRILL IS SUPPORTED BY CONTINUOUS FLEXIBLE LEADS HELD ON ONE OR MORE HIGH-SPEED REELS. WITHDRAWALS AND REPLACEMENT TIMES CAN BE REDUCED BY AN ORDER-OF-MAGNITUDE. COMMERCIAL USES INCLUDE STANDARD CORING APPLICATIONS AS WELL AS INTERMI ...

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 ...

"The objective of this proposal is to evaluate 128-bit game consoles like Sony PS2 and Microsoft X-box and graphics processing units for applications involving visualization, simulation and navigation of complex datasets. It will include evaluating theprogramming environments, memory and processing capabilities for general applications. In Phase I, we evaluated the Sony PS2 platform as well as t ...

In phase I, Dot Metrics Technologies demonstrated the feasibility of a new method of introducing deep-green luminescent nanostructure into semiconductor materials for light-emitting device applications. The materials were used to fabricate and characterize preliminary optoelectronic device test structures. In phase II, Dot Metrics Technologies proposes to leverage these new materials and methods i ...

This Small Business Innovation Research (SBIR) Phase II project integrates the imaging system developed in Phase I with a smart-sensor injection system that can inject or sample from the cavity underlying the early chicken embryo with high levels of accuracy accompanied with improved hatch when compared to manual methods. The Phase I work showed that it was possible to image and detect the blasto ...

This Small Business Innovation Research Phase II project deals with the problems of reconstructing complex free-form shapes from measured data. Raindrop Magic's primary interest is to produce well-structured, high-quality CAD models. Several techniques exist to reach this goal; unfortunately, automatic surfacing systems provide only rough approximations and do not capture the original design int ...

This Small Business Innovation Research (SBIR) Phase II project will investigate applications of Combinatorial Morse Theory in Reverse Engineering, a field that focuses on converting physical objects into a digital representation suitable for CAD, CAM, and CAE. The biggest challenge in this field is to automate the conversion process while producing a model that meets all the requirements of downs ...
