—an interplay between mobile devices and static sensor nodes is envisioned in the near future. This will enable a heterogeneous design space that can offset the stringent resourc...
Abstract. A top-k OLAP query groups measures with respect to some abstraction level of interesting dimensions and selects the k groups with the highest aggregate value. An example ...
We present a simple but powerful algorithm for optimizing the usage of hardware occlusion queries in arbitrary complex scenes. Our method minimizes the number of issued queries an...
Abstract. In today’s global environment, the structure and presentation of information may depend on the underlying context of the user. To address this issue, in previous work w...
Query formulation is an essential part of successful information retrieval. The challenges in formulating effective queries are emphasized in web information search, because the w...
