— In robotics, appearance-based topological map building consists in infering the topology of the environment explored by a robot from its sensor measurements. In this paper, we ...
—Fast frequency acquisition is crucial for phase-locked loops (PLLs) used in portable devices, as on-chip clocks are frequently scaled down or up in order to manage power consump...
— In this paper, we present a novel algorithm for reducing sidelobe interference power levels in OFDM-based cognitive radios. Existing techniques for sidelobe suppression can be ...

Abstract— In this paper, the design of distributed spacefrequency codes (DSFCs) for wireless relay networks employing the amplify-and-forward (AAF) protocol is considered. The te...
— The Semantic Web can be viewed as largely about “Knowledge meets the Web”. Thus its vision includes ontologies and rules. A key requirement for the architecture of the Sema...
