Reuse of design rationales, while essential to long-term goals of both design rationale capture and software reuse, presents significant challenges to current technology. Organon Motives, Inc. (OMI) and Knowledge Evolution, Inc. (KEI) propose a system, MIRIAD (Models for Interoperable Rationale, Inference and Alternative Designs), for recording and managing reusable rationale in semantically stru ...

THIS PROPOSAL INVOLVES THE DEVELOPMENT OF TECHNIQUES FOR AUTOMATED PROCESSING OF SNYTHETIC APERTURE RADAR (SAR) IMAGERY. SPECIFICALLY, THIS TASK INVOLVES FINDING ALTERNATING CURRENT (AC) POWER LINES AND RELATED STRUCTURES FROM HIGH-RESOLUTION AIRBORNE SAR (ASAR) IMAGES. WE WILL IDENTIFY AREAS FOR IMPROVEMENT AND DEVELOP NEW TECHNIQUES AS NECESSARY TO STRENGTHEN WEAK AREAS. WE WILL ESTABLISH A METH ...

There is an explosion of 3-D graphics technology in the mainstream commercial market. A $10,000 3-D graphics PC outperforms a $100,000 UNIX 3-D graphics workstation in virtually all aspects, in particular the 3-D rendering speed. We have an opportunity to exploit this new technology so every analyst or war-fighter can use their desktop PC to visualize in real-time 3-D urban and terrain data. In ...

COMPOSITES HAVE ESTABLISHED THEIR ADVANTAGEOUS FOR HIGH PERFORMANCE AND WEIGHT REDUCTION, PARTICULARLY IN TENSION-LOADED STRUCTURES LOADED. THESE MATERIALS POSSESS HIGH STIFFNESSES AND TENSILE STRENGTHS COMBINED WITH LOW DENSITY, AND THEY HAVE BECOME THE MATERIAL OF CHOICE IN NUMEROUS HIGH PERFORMANCE APPLICATIONS. THE SAME CANNOT BE SAID FOR COMPRESSIVE PROPERTIES OF THESE MATERIALS, WHICH ARE OF ...

MAN-PORTABLE ELECTRONICS EQUIPMENT SUCH AS THE MINI GLOBAL POSITIONING SYSTEM RECEIVER IS CURRENTLY POWERED BY HEAVY CHEMICAL BATTERIES. A WIND-UP SPRING DEVICE, CAPABLE OF PRODUCING 4W AT 12V FOR 5 MIN AT ONE WINDING, WOULD BE A DESIRABLE SUBSTITUTE FOR BATTERIES. UNFORTUNATELY, CALCULATIONS SHOW THAT THE WEIGHT AND BULK OF A SPRING MECHANISM WOULD BE UNACCEPTABLE. INSTEAD, A SMALL, HIGHLY EFFICI ...

Physical Sciences, Inc. (PSI) proposes to develop an etching tool based upon its patented Fast Atom Sample Tester (FAST) technology that addresses a critical processing problem faced by manufacturers of Bonded wafers. The fabrication process for bonded wafers results in a 5 mm wide strip of partially delaminated silicon along the perimeter of the 8-in. wafer which can serve as a source of unaccep ...

We propose the development of commercial software for the modeling of electronic, optical and opto-electronic properties of quantum semiconductor heterostructures. The work over Phase 1 will provide electronic bandstructure modeling using the finite element method and full-zone tight-binding computation of electronic states in multiple quantum wells, wires, and dots. Any of the Group III-V or II ...
