A combined fuzzy AHP-goal programming approach to assembly-line selection
(IOS Press, 2007)In mass production assembly-line balancing (ALB) problem has been a critical and repetitive issue for companies for long time. On the other hand equipment selection for stations has also been another important problem at ... -
Joint data detection and channel estimation for uplink MC-CDMA systems over frequency selective channels
(Springer, 2007)This paper is concerned with joint channel estimation and data detection for uplink multicarrier code-division multiple-access (MC-CDMA) systems ill the presence of frequency fading channel. The detection and estimation ... -
Iterative channel estimation and decoding of turbo coded SFBC-OFDM systems
(IEEE, 2007)We consider the design of turbo receiver structures for space-frequency block coded orthogonal frequency division multiplexing (SFBC-OFDM) systems in the presence of unknown frequency and time selective fading channels. ... -
Thermal rearrangement of 2-acetoxy-266-trimethylbicyclo[3.1.0]hexane: Theoretical elucidation of the mechanism
(Elsevier Science, 2007)Bicyclohexenes are believed to be the immediate precursors of aromatic compounds. As a part of the exploratory study of thermal aromatization reactions 266-trimethylbicyclo[3.1.0]hexan-2-ol and its ester derivative ... -
Design of practical matching networks with lumped elements via modeling
(IEEE, 2007)It is a common practice to utilize commercially available software tools to design matching networks for wireless communication systems. Most of these tools require a properly selected matching network topology with good ... -
Performance of space-time coded systems with transmit antenna selection
(IEEE, 2007)We deal with transmit antenna selection for space-time coded (STC) systems over multiple input multiple output (MIMO) channels. Using pairwise error probability analysis and simulation results we show that transmit antenna ... -
Reflectance-based Foster impedance data modeling
(Fachverlag Schiele Schon, 2007)A reflectance-based method is presented to model a set of given Foster impedance data as a lossless singly terminated two-port consisting of lumped-elements in short or open termination. The basis of the new method rests ... -

An analytic network process-based approach to concept evaluation in a new product development environment
(Taylor & Francis, 2007)Selecting the best product concept is one of the most critical tasks in a new product development (NPD) environment. Making decisions at this stage becomes very difficult due to imprecise and uncertain product requirements. ... -
The effect of a bump in an elastic tube on wave propagation in a viscous fluid of variable viscosity
(Elsevier Science, 2007)In the present work treating the arteries as a thin walled prestressed elastic tube with a bump and the blood as a Newtonian fluid of variable viscosity we have studied the propagation of weakly nonlinear waves in such a ... -
Production of electron-positron pairs by nuclear dissociation in peripheral heavy ion collisions
(Elsevier, 2007)The STAR Collaboration at the Relativistic Heavy Ion Collider present data on electron-positron pair production accompanied by nuclear breakup at small impact parameters where the simultaneous excitation of the two ions ... -
Text area detection in digital documents images using textural features
(Springer, 2007)In this paper we propose a new texture-based method for extraction of text areas in a complex document image. Gabor filter motivated by the multi-channel filtering approach of Human Visual System (HVS) has been employed ... -
Iterative Receiver for DS-CDMA Systems in the Presence of Time-Varying Channels
(IEEE, 2008)In this paper we present an efficient iterative receiver structure of tractable complexity for joint multiuser detection and multichannel estimation (JDE) of direct-sequence code-division multiple-access systems operating ... -

Outage Diversity for Distributed Estimation over Parallel Fading Channels
(IEEE, 2008)In this paper we study the outage diversity in distributed estimation over parallel fading channels. We find tight upper and lower bounds on the diversity order and show that they are arbitrarily close under certain ... -
Distributed estimation over parallel fading channels with channel estimation error
