Comparison of PI controllers designed for the delay model of TCP/AQM networks
(Elsevier Science BV, 2013)One of the major problems of communication networks is congestion. In order to address this problem in TCP/IP networks, Active Queue Management (AQM) scheme is recommended. AQM aims to minimize the congestion by regulating ... -
Salient point region covariance descriptor for target tracking
(Spie-Soc Photo-Optical Instrumentation Engineers, 2013)Features extracted at salient points are used to construct a region covariance descriptor (RCD) for target tracking. In the classical approach, the RCD is computed by using the features at each pixel location, which increases ... -
Prediction of partial synchronization in delay-coupled nonlinear oscillators, with application to Hindmarsh-Rose neurons
(IOP Publishing LTD, 2013)The full synchronization of coupled nonlinear oscillators has been widely studied. In this paper we investigate conditions for which partial synchronization of time-delayed diffusively coupled systems arises. The coupling ... -
A Generalized Laplacian of Gaussian Filter for Blob Detection and Its Applications
(IEEE-Inst Electrical Electronics Engineers Inc, 2013)In this paper, we propose a generalized Laplacian of Gaussian (LoG) (gLoG) filter for detecting general elliptical blob structures in images. The gLoG filter can not only accurately locate the blob centers but also estimate ... -
Theoretical investigation of InAs/GaSb type-II pin superlattice infrared detector in the mid wavelength infrared range
