National security culture in Turkey: a qualitative study on think tanks
(Ahmet Yesevi University, 2012)
This article examines the role that think tanks have played in the formulation of national security and a culture of security through field research conducted on fourteen think tanks located in Istanbul and Ankara. In ...
An evolutionary approach for tuning parametric Esau and Williams heuristics
(Palgrave Macmillan Ltd., 2012)
Owing to its inherent difficulty many heuristic solution methods have been proposed for the capacitated minimum spanning tree problem. On the basis of recent developments it is clear that the best metaheuristic implementations ...
Temperature effect on the swelling of PAAm-kappa-carrageenan composites
(Wiley-Blackwell, 2012)
The steady-state fluorescence (SSF) technique was used for studying swelling of disc-shaped polyacrylamide (PAAm)-kappa-carrageenan (kappa C) composites which were prepared by free-radical crosslinking copolymerization at ...
Channel estimation in underwater cooperative OFDM system with amplify-and-forward relaying
(IEEE, 2012)
This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the presence of sparse underwater acoustic ...
Prediction of the monomer-monomer ınterface region of the beta 2Ar homo-dimer receptor via docking experiments
(Cell Press, 2012)
[Abstract Not Available]
Performance of spatial modulation in the presence of channel estimation errors
(IEEE-INST Electrical Electronics Engineers Inc, 2012)
This work investigates the negative effects of channel estimation errors on the performance of spatial modulation (SM) when operating over flat Rayleigh fading channels. The pairwise error probability of the SM scheme is ...
Railway heritage of Istanbul and the Marmaray Project
(Taylor & Francis Inc, 2012)
This study explores the significance of Istanbul's railway heritage and discusses the criteria for evaluating the historical importance architectural value and social issues surrounding the city's rail system leading into ...
Temperature dependence of oxygen diffusion into polymer/carbon nanotube composite films
(Wiley-Blackwell, 2012)
This study examines the transport properties of polystyrene (PS)/multiwalled carbon nanotube (MWNT) composite films taking into consideration both MWNT composition and temperature via fluorescence technique. Three different ...
Monitoring the gelation of polyacrylamide-sodium alginate composite by fluorescence technique
(Taylor & Francis Ltd, 2012)
Polyacrylamide (PAAm)-sodium alginate (SA) composite was prepared with different amounts of SA varying in the range between 0.06% and 2% (w/v). The PAAm-SA composite was characterized by the steady-state fluorescence ...
Elastic percolation of swollen polyacrylamide (PAAm)-multiwall carbon nanotubes composite
(Taylor & Francis Ltd, 2012)
Polyacrylamide (PAAm)-multiwalled carbon nanotube (MWNT) composites were prepared via free radical cross-linking copolymerization with different amounts of MWNTs varying in the range between 0.1 and 50 wt%. The mechanical ...
