The paper studies the optimal placement of multiple cameras and the selection of the best subset of cameras for single target localization in the framework of sensor networks. The cameras are assumed to be aimed horizontally around a room. To conserve both computation and communication energy, each camera reduces its image to a binary “scan-line” by performing simple background subtraction followed...
Pawlak recently introduced rough set flow graphs (RSFGs) as a graphical framework for reasoning from data. No study, however, has yet investigated the complexity of the accompanying inference algorithm, nor the complexity of inference in RSFGs. In this paper, we show that the traditional RSFG inference algorithm has exponential time complexity. We then propose a new RSFG inference algorithm that exploits...
An integrated, completely balanced broadband transceiver front end for operation in the cm- and mm-wave range is presented. It is compatible with our ultra-wideband M-sequence baseband system. The transceiver front end is based on the application of specific integrated circuits (ASICs) designed for a 0.25 μm SiGe process with fT/fmax = 180/220 GHz. To achieve an optimum reasonable...
As a sort of MPF(median and/or paired fin propulsion), pectoral fins propulsion makes fish easier to maneuver than other propulsion, according to the well-established classification scheme proposed by Webb in 1984. Pectoral fins propulsion is classified into oscillatory propulsion, undulatory propulsion and compound propulsion. Pectoral fins oscillatory propulsion, is further ascribable to two modes:...
In the incremental-iterative analysis of elastic nonlinear structures, great saving in computation can be achieved if distinction is made between the predictor and corrector phases. The predictor relates to solution of the structural displacements for given load increments, which affects only the number of iterations. For the sake of iteration, the equations used in the predictor need not be exact,...
