Hashing is one of the fundamental techniques used to implement query processing operators such as grouping, aggregation and join. This paper studies the interaction between modern...
Abstract. In this paper we report on a feasibility study in reengineering legacy systems towards a model-driven architecture (MDA). Steps in our approach consist of (1) parsing the...
Abstract. Approximate Policy Iteration (API) is a reinforcement learning paradigm that is able to solve high-dimensional, continuous control problems. We propose to exploit API for...
Traditional process support systems offer the promise of software assembled from service elements. The typical approach is a static composition of atomic processes to more powerfu...
Abstract. Automatic performance analysis of parallel programs can be accomplished by scanning event traces of program execution for patterns representing inefficient behavior. The ...
