— This work presents an UWB testbed for reduced data rates with capabilities of measuring range and location. The transmitter uses Time Hopping spread spectrum codes to reduce th...
—The multiple-access interference (MAI) limits the performance of the DS-CDMA uplink transmission. 2 dimensional (2D) spread/chip-interleaved DS-CDMA is an MAI-free system, where...
We propose a two-stage recognition system for detecting arm gestures related to typical meal intake. Information retrieved from such a system can be used for automatic dietary mon...
Algorithms by which peers join and leave structured overlay networks can be classified as passive or active. Passive topology maintenance relies on periodic background repair of n...
Abstract. As an ongoing effort to develop a computer aided system for the detection of masses on mammograms, we propose on this work a new model-based segmentation algorithm. The a...
