Award Data

In Phase I, ALPHATECH will define a model-neutral data structure and supporting access mechanisms that will provide interoperability between different modeling methodologies in support of large scale systems engineering. The model-neutral data structure will provide a common data representation of the model-specific data that is contained in the different modeling methods. The access mechanisms ...

Project will demonstrate the feasibility of combining signatures from multiple sensor domains to the problem of detecting, localizing and characterizing an underground facility. The Phase I effort will focus on establishing, integrating, and validating models for the source and propagation phenomenologies associated with electromagnetic, seismic, and acoustic signatures of mechanical and electro ...

CASE-BASED REASONING (CBR) INVOLVES THE USE OF SUITABLE CASES OF PAST EXPERIENCE TO INTERPRET OR SOLVE A NEW PROBLEM. THIS PROPOSED WORK EXPLORES INCORPORATING CBR TECHNIQUES IN MIXED-PARADIGM KNOWLEDGE-BASED APPLICATIONS. IN MANY POTENTIAL CBR APPLICATIONS, CBR APPROACHES ALONE ARE INSUFFICIENT AND MUST BE COMBINED WITH OTHER PROBLEM-SOLVING TECHNIQUES IN A MIXED-PARADIGM CBR FRAMEWORK. OUR APPRO ...

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 ...

A BRUSHLESS ALTERNATOR USING VERY HIGH ENERGY PRODUCT PERMANENT MAGNETS WILL BE COMBINED WITH HIGH EFFICIENCY SOLID-STATE VOLTAGE CONVERSION TECHNOLOGY TO DEMONSTRATE PRECISE ELECTRICAL POWER GENERATION FOR ELECTRONICS ONBOARD MINIATURE AIRCRAFT. PHASE I WILL INCLUDE DESIGN OPTIMIZATION, FABRICATION, AND TESTING OF A PROTOTYPE ALTERNATOR, CONCLUDING WITH A DEMONSTRATION OF THE PROTOTYPE DRIVEN BY ...

This proposal addresses the requirements for a Micro Aerial Vehicle (uAV) communications systems. The RF link between an airborne uAV and uAV Ground Control Station (MGCS) presents significant technical challenges. The central issue is the competing requirements of communications system complexity necessary to overcome the multiple communication link degradations versus the necessity for miniatu ...

The development of a micro unmanned vehicle requires an extremely small, lightweight navigation system. The combination of a miniature GPS receiver with micro-machined accelerometer/gyros (MGIMU) provides the ideal solution. When integrated with its own processor performing navigation, Kalman filtering and flight control/guidance, a powerful precision aided navigation system is produced. The se ...
