The main result is the development, and delay comparison based on Logical Effort, of a number of high speed circuits for common arithmetic and related operations using threshold l...
In this paper we develop a new method for solving queries on semistructured data. The main idea is to see a database as a Kripke Transition System (a model) and a query as a formul...
This work presents a visualization algorithm for defeasible logic rule bases as well as a software tool that applies this algorithm, according to which, a directed graph is produce...

We present local Hoare reasoning about data update, using Context Logic for analysing structured data. We apply our reasoning to tree update, heap update which is analogous to loc...
Most information extraction (IE) systems identify facts that are explicitly stated in text. However, in natural language, some facts are implicit, and identifying them requires â€...
