Digital crime and punishment: Turkish online journalism under siege
(International Institute of Informatics and Systemics IIIS, 2012)
Turkish mass media since its beginnings in late 19th century has aimed to gain its role as the fourth estate in Turkish political scene. The freedom of press has been at the paramount of discussions since the foundation ...
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 ...
Pilot-aided bayesian MMSE channel estimation for OFDM systems: Algorithm and performance analysis
(2004)
This paper proposes a computationally efficient pilot-aided minimum mean square error (MMSE) channel estimation algorithm for OFDM systems. The proposed approach employs a convenient representation of the discrete multipath ...
On the inverse point-source problem of the poisson equation
(Istanbul University, 2005)
In this work a basic inverse heat conduction problem of a simple 2-D model with steady state heat source is taken into view. The physical problem is for a square region with uniform thermophysical properties and a point ...
The use of autologous pericardium for complicated mitral valve annulus
(Asia Publishing Exchange Pte Ltd, 2004)
The study aims to discuss annular repair using the autologous pericardial patch in cases with severe mitral ring calcification and endocarditis during mitral valve replacement. In the study annular reconstruction was applied ...
Pilot assisted channel estimation for asymmetrically clipped optical OFDM over visible light channels
(Institute of Electrical and Electronics Engineers Inc., 2017)
The Visible Light Communication(VLC) has drawn significant attention recently for wireless communication in addressing the performance limitations of wireless systems due to the scarcity of bandwidth. In VLC system the ...
Exploring distinct binding site regions of beta(2)-adrenergic receptor via coarse-grained molecular dynamics simulations
(Scientific Technical Research Council Turkey-Tubitak, 2013)
beta(2)-Adrenergic receptor (beta(2)AR) is a G protein-coupled receptor that is highly flexible and able to recognize a wide range of ligands through its conformational variations. Active and inactive conformations revealed ...
