— In contrast to the traditional wireless sensor network (WSN) applications that perform only data collection and aggregation, new generation of information processing applicatio...
Aggregating spatial objects is a necessary step in generating spatial data cubes to support roll-up/drill-down operations. Current approaches face performance bottleneck issues wh...
Traditional location-based services recommend nearest objects to the user by considering their spatial proximity. However, an object not only has its distance but also has its dir...
This paper tackles an important aspect of the variational problems involving active contours, which has been largely overlooked so far: the optimization by gradient flows. Classic...
—In this paper a spatial phase coding (SPC) scheme is investigated for its application in OFDM systems. With SPC the phase relation of the signals between multiple transmit anten...
