- Data Mining of Approximate Functional Dependencies using an Improvement Threshold
We are looking at improved search algorithms and metrics for the mining of functional dependencies.
Our work attempts to contribute in two areas. The first is the use of Improvement as a constraint to return a
non-minimal set of approximate functional dependencies (AFDs). The second area is the development of Adaptive
Approximation and Adaptive Improvement which generate thresholds for Approximation and Improvement instead of
user inputed ones. Implementation is being done in C/C++ using STL.

- Enterprise Architecture Frameworks
This project addresses issues of design at the broadest scope - the
scope of enterprises encompassing multiple organizations and of
systems where software provides both components for those systems and
means for management of enterprise complexity. In particular, it
seeks to complete and apply a formalization of enterprise
architectural frameworks - organizing principles and mechanisms that
apply at the highest level. Our vision of "Science of Design" is of
multiple models, of principles and mechanisms which arrange and
articulate these models, The science is the manner in which design is
driven from specification and propagates into realization. A unique
aspect of our proposal is the use of the International Standards
Organization process to gather input and vet contributions.
