Recent Projects:

• NSF Center for the Design of Analog / Digital Circuits (CDADIC) 1990-1994
  The Circuit Designer's Apprentice / High Level Circuit Synthesis Techniques $150,000 / 3 years

This research investigated a system-level analog-digital development environment called the Circuit Designer's Apprentice, particularly focusing on re-use and re-engineering. A sub-system called the Circuit Design Retrieval System (CDRS) uses fuzzy query and ranked retrieval to identify reusable circuit designs from a repository. Another sub-system called the Circuit Recognizer and Redesign Aide (CRRA) uses reconstructive derivational analogy (RDA) and expert system rules to recognize the function of an existing circuit design and provide a design history tree, from which a modified circuit can be constructed.

• Predictive-Adaptive HF Packet Radio Network Management
  funding for this work is pending with a student MS thesis and research as background work (1994-1996)

This research is investigating the possible improvement to HF Packet Radio Network Management by recognizing and adapting to periodic solar effects on the ionospheric propagation of HF radio signals.
