Sustainability has recently emerged as a key issue in process systems engineering (PSE). Mathematical programming techniques offer a general modeling framework for including enviro...
In this paper, we study the problem of processing multiple queries in a wireless sensor network. We focus on multiquery optimization at the base station level to minimize the numb...
We apply multiple query optimization to batches of pull (on-demand) requests in a mobile database system. The resulting view can answer several queries at once, and it is broadcas...
A multi-clip query requests multiple video clips. In this paper we address the multi-clip query optimization problem. We propose a new heuristics called Restricted Search Interval...

While much work has addressed the problem of maintaining materialized views, the important question of optimizing queries in the presence of materialized views has not been resolv...
