— Accurate detection of spectrum opportunities within the frequency band of an orthogonal frequency division multiple access (OFDMA) system is a critical requirement for the real...
Abstract— We derive a local minimum of an elastic potential energy due to the deformation of a hemispherical soft fingertip, and propose a quasi-static manipulation algorithm us...
A strategy for energy saving in wireless sensor networks is to manage the duty cycle of sensors, by dynamically selecting a different set of nodes to be active in every moment. We ...
: Ad hoc wireless networks are a special type of wireless network in which a collection of mobile hosts (nodes) with wireless network interfaces may form a temporary network withou...
We present a novel off-line algorithm for target segmentation and tracking in video. In our approach, video data is represented by a multi-label Markov Random Field model, and seg...
