The effect of channel resolution on compressed sensing based Ultra-Wideband channel estimation [Kanal çözünürlü?ünün sıkıştırılmış algılama tabanlı ultra geni?ş bantlı kanal kesti?ri?mi?ne etki?si?]
(2011)
Ultra short pulses are transmitted in Ultra-Wideband (UWB) communications. As a result of this pulses at the receiver can be resolved individually due to the sparse structure of the channel. Due to these properties the UWB ...
Trellis coding for spatial modulation [Uzaysal modulasyon i?çi?n kafes kodlama]
(2011)
In this study by combining trellis coding with spatial modulation (SM) a new multiple-input multiple output (MIMO) communication scheme called trellis coded spatial modulation (TC-SM) is proposed. For uncorrelated Rayleigh ...
Power flow using thread programming
(2011)
Power flow problem which is one of the most important applications in power system is solved using OpenMP Application Program Interface (API) a thread based programming technique for the shared memory programming environments. ...
A preconditioner for transient stability time domain simulation
(2011)
Transient Stability analysis which is one of the most important tasks of power system dynamic security analysis determines the dynamic behaviour of the power system after a large disturbance. Differential and algebraic ...
New Trellis Code Design for Spatial Modulation
(IEEE-INST Electrical Electronics Engineers Inc, 2011)
Spatial modulation (SM) in which multiple antennas are used to convey information besides the conventional M-ary signal constellations is a new multiple-input multiple-output (MIMO) transmission technique which has recently ...
Study of Thermal Phase Transitions in Iota Carrageenan Gels via Fluorescence Technique
(Wiley-Blackwell, 2011)
The effect of carrageenan concentration on thermal phase transitions of the iota carrageenan gels was investigated by using fluorescence technique. During heating and cooling processes scattered light I(sc) and fluorescence ...
A Study of 8th Graders’ Perceptions of Socio-Cultural Perspective of Creativity by Using Information Technology Tools in realisation of Homework Goals
(The Turkish Online Journal of Educational Technology, 2011)
The study aims at evaluating the perceptions of 8(th) graders towards the use of information technologies ranging from the internet and multimedia tools in socio-cultural perspective of creativity while they are doing their ...
Modeling of claim exceedances over random thresholds for related insurance portfolios
(Elsevier Science Bv, 2011)
Large claims in an actuarial risk process are of special importance for the actuarial decision making about several issues like pricing of risks determination of retention treaties and capital requirements for solvency. ...
Emerging Markets: Institutional Reforms FDI Capital Mobility and Abnormal Returns Introduction

Leveraging saving-based algorithms by master-slave genetic algorithms
(Pergamon-Elsevier Science Ltd, 2011)
Saving-based algorithms are commonly used as inner mechanisms of efficient heuristic construction procedures. We present a general mechanism for enhancing the effectiveness of such heuristics based on a two-level genetic ...
