Coarse-to-fine approaches use sequences of increasingly fine approximations to control the complexity of inference and learning. These techniques are often used in NLP and visio...
We focus on data gathering problems in energy-constrained wireless sensor networks. We study store-and-gather problems where data are locally stored on the sensors before the data ...
We consider the class of database programs and address the problem of minimizing the cost of their exchanges with the database server. This cost partly consists of query execution...
Abstract. We present a method to specify software for a special kind of safetycritical embedded systems, where sensors deliver low-level values that must be abstracted and pre-proc...
—In this paper, we propose a vibration driven energy harvesting platform based on piezoelectric material. A new maximum power point tracking (MPPT) method for this platform is al...
