Support vector machines based target tracking techniques
(IEEE, 2006)This paper addresses the problem of aplying powerful statistical pattern classification algorithms based on kernels to target tracking. Rather than directly adapting a recognizer we develop a localizer directly using the ... -
A numerical method for frequency determination in the astable cellular neural networks with opposite-sign templates
(IEEE, 2006)In this study a numerical method is proposed to determine the oscillation frequencies in the astable cellular neural networks with opposite-sign templates [1]. This method depends on the training of a multilayer perceptron ... -
The effects of higher-order approximations in a fluid-filled elastic tube with stenosis
(Verlag der Zeitschrift fur Naturforschung, 2006)Treating arteries as thin-walled prestressed elastic tubes with a narrowing (stenosis) and blood as an inviscid fluid we study the propagation of weakly nonlinear waves in such a fluid-filled elastic tube by employing the ... -
On sectional curvatures of a Weyl manifold
(2006)In this paper it is proved that if at each point of a Weyl manifold the sectional curvature is independent of the plane chosen then the Weyl manifold is locally conformal to an Einstein manifold and that the scalar curvature ... -
Power transfer networks at RF frequencies "New design procedures with implementation roadmap"
(IEEE, 2006)The purpose of this work is to provide the necessary background to design wide-band power transfer two-ports, or so-called broadband matching networks, at radio frequencies for wireless communication systems. The importance ... -
Optical and structural properties of Ta2O5-CeO2 thin films
(Elsevier Science Bv, 2007)In this study the sol-gel spin-coating method has been used to make Ta2O5-CeO2 thin films. These films have been prepared in various composition ratios to observe changes in their optical and structural properties. Reflectance ... -
Influence of pH on the optical and structural properties of spin coated CeO2-TiO2 thin films prepared by sol-gel process
(Elsevier Science Bv, 2007)Optical and structural properties of mixed CeO2-TiO2 thin films have been investigated by varying the pH of the coating sol. The films were prepared by sol-gel process using spin-coating technique with a spin speed of 2500 ... -

Space-time coded systems with joint transmit and receive antenna selection
(IEEE, 2007)This paper studies performance of space-time coded (STC) systems with joint transmit and receive antenna selection over multiple input multiple output (MIMO) flat and frequency-selective (FS) fading channels. Specifically ... -
Iterative channel estimation techniques for uplink MC-CDMA systems
(IEEE, 2007)In this work maximum likelihood (ML) channel estimation for uplink multicarrier code-division multiple-access (MC-CDMA) systems is considered in the presence of frequency fading channel. The expectation-maximization (EM)- ... -
Distributed estimation with channel estimation error over orthogonal fading channels
(IEEE, 2007)We study distributed estimation of a source corrupted by an additive Gaussian noise and observed by sensors which are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. The fading ... -
Channel estimation for MIMO-OFDM systems in fixed broadband wireless applications
(IEEE, 2007)Systems employing multiple transmit and receive antennas known as multiple input multiple output (MIMO) systems can be used with OFDM to improve the resistance to channel impairments. Thus the technologies of OFDM and MIMO ... -
