Technical report TR08-07. In gene expression microarray data analysis, biclustering has been demonstrated to be one of the most effective methods for discovering gene expression patterns under various conditions. We present in this study a framework to take advantage of the homogeneously...
Technical report TR09-14. We consider the problem of aggregation convergecast scheduling in wireless sensor networks. Aggregation convergecast differs from regular convergecast in that it accommodates transmission dependencies that allow in-network aggregation to be performed. We formulate the...
Technical report TR08-02. We consider the problem of vehicle classification using acoustic signals captured within a sensor network. The sensors perform collaborative decision and/or data fusion in a distributed and energy efficient manner. We present a distributed cluster-based algorithm,...
Technical report TR09-01. Finding the top-k values is an important type of aggregation query in wireless sensor networks. Previous proposals relied on a given underlying logical tree topology for data aggregation/forwarding, but did not pay due attention to the role of such topology. In this...
