Abstract. In this paper we deal with the problem of finding an optimal query execution plan in database systems. We improve the analysis of a polynomial-time approximation algorit...
We present a polynomial upper bound for flattening of UML statecharts. An efficient flattening technique is derived and implemented in SCOPE—a code generator targeting constra...
This paper addresses verifying the timing of circuits containing level-sensitive latches in the presence of cross talk. We show that three consecutive periodic occurrences of the ...
We present a new approach to static program analysis that permits each expression in a program to be assigned an execution time estimate. Our approach uses a time system in conjun...
In this work we study the design of secure protocols for linear algebra problems. All current solutions to the problem are either inefficient in terms of communication complexity o...
