Synthesis of cascaded lossless commensurate lines
(IEEE-INST Electrical Electronics Engineers Inc, 2008)A scattering transfer matrix factorization based algorithm for cascaded lossless commensurate line synthesis is presented. The characteristic impedances of the extracted commensurate lines and the reflection factors of the ... -
Abstraction in FPGA implementation of neural networks
(World Scientific and Engineering Academy and Society, 2008)A model for FPGA implementation of multilayer perceptron neural networks is presented. The model tries to incorporate object oriented design principles in the analysis training and design of components using hardware ... -
An Integrated Software Architecture for Bandwidth Adaptive Video Streaming
(World Acad Sci Eng & Tech-Waset, 2008)Video streaming over lossy IP networks is very important issues due to the heterogeneous structure of networks. Infrastructure of the Internet exhibits variable bandwidths delays congestions and time-varying packet losses. ... -
Performance of stack equalizer over frequency selective fading channels [Frekansa ba?lı sönümlemeli kanallarda yi?it denkleştiricinin başarımı]
(2008)In this paper the performance of the low complexity modified stack equalizer over frequency-selective fading channels is inspected. With the help of simulation results it is illustrated that by sacrificing the computational ... -
Fast multi-view face trackingwith pose estimation
(2008)In this paper a fast and an effective multi-view face tracking algorithm with head pose estimation is introduced. For modeling the face pose we employ a tree of boosted classifiers built using either Haar-like filters or ... -
Performance of space time codes with transmit antenna selection over frequency selective fading channels in the presence of channel estimation errors
(2008)This paper presents a performance analysis of space-time coded systems with transmit antenna selection over frequency selective fading channels when the erroneously estimated fading coefficients are available only at the ... -
A memetic random-key genetic algorithm for a symmetric multi-objective traveling salesman problem
(Pergamon-Elsevier Science Ltd, 2008)This paper proposes a methodology to find weakly Pareto optimal solutions to a symmetric multi-objective traveling salesman problem using a memetic random-key genetic algorithm that has been augmented by a 2-opt local ... -

New pyrazoline bearing 4(3H)-quinazolinone inhibitors of monoamine oxidase: Synthesis biological evaluation and structural determinants of MAO-A and MAO-B selectivity
(Pergamon-Elsevier Science Ltd, 2009)A new series of pyrazoline derivatives were prepared starting from a quinazolinone ring and evaluated for antidepressant anxiogenic and MAO-A and -B inhibitory activities by in vivo and in vitro tests respectively. Most ... -
A hybrid approach to concept selection through fuzzy analytic network process
(Pergamon-Elsevier Science Ltd, 2009)Evaluating conceptual design alternatives in a new product development (NPD) environment has been one of the most critical issues for many companies which try to survive in the fast-growing world markets. Therefore most ... -
Histone Deacetylase Inhibition Activity and Molecular Docking of (E )-Resveratrol: Its Therapeutic Potential in Spinal Muscular Atrophy
(Wiley, 2009)Spinal muscular atrophy is an autosomal recessive motor neuron disease that is caused by mutation of the survival motor neuron gene (SMN1) but all patients retain a nearly identical copy SMN2. The disease severity correlates ... -
Oxygen diffusion into polystyrene-bentonite films
(Elsevier, 2009)A simple fluorescence technique is proposed for the measurement of the diffusion coefficient of oxygen into polystyrene-clay composite films. The composite films were prepared from the mixture of surfactant-free pyrene ... -
A Robust Localization Framework to Handle Noisy Measurements in Wireless Sensor Networks
