A sparsity-preserving spectral preconditioner for power flow analysis
(TUBITAK Scientific & Technical Research Council Turkey, 2016)Due to the ever-increasing demand for more detailed and accurate power system simulations the dimensions of mathematical models increase. Although the traditional direct linear equation solvers based on LU factorization ... -
Spatial Constellation Design Based Generalized Space Shift Keying for Physical Layer Security of Multi-User MIMO Communication Systems
(Institute of Electrical and Electronics Engineers Inc., 2021)We propose a novel spatial constellation design (SCD) method with generalized space shift keying (GSSK-SCD) signaling for physical layer security (PLS) in multi-user (MU) multiple-input multiple-output (MIMO) communication ... -
Spatial Modulation Aided Physical Layer Security for NOMA-VLC Systems
(IEEE-Inst Electrical Electronics Engineers Inc, 2023)We consider the physical layer security (PLS) problem in multi-user non-orthogonal multiple access (NOMA) enabled multiple-input multiple-output (MIMO) visible light communication systems intercepted by a passive eavesdropper ... -
Special issue on broadband mobile communications at very high speeds
(Springer International Publishing Ag, 2012)[Abstract Not Available] -
A spectral divide and conquer method based preconditioner design for power flow analysis
(2010)Power system simulations most of the time require solution of a large sparse linear system. Traditional methods such as LU decomposition based direct methods are not suitable for parallelization in general. Thus Krylov ... -
Spectroscopic study of film formation from polystyrene latex/TiO2 nanocomposites prepared by dip-coating method
(Wiley-Blackwell, 2014)In this study we investigated the influence of TiO2 content and thickness of polystyrene (PS) template on film-formation behavior of PS/TiO2 composites using fluorescence and ultraviolet-visible techniques in conjunction ... -
The speed of stock price adjustment to corporate announcements: Insights from Turkey
(Elsevier, 2020)The market reaction speeds to the news flow are currently measured at the millisecond level in developed markets. We investigate, using a unique setting from Turkey, whether the market reaction speeds in less sophisticated ... -
Spin-s spin-glass phases in the d=3 Ising model
(Amer Physical Soc, 2021)All higher-spin (s >= 1/2) Ising spin glasses are studied by renormalization-group theory in spatial dimension d = 3, exactly on a d = 3 hierarchical model and, simultaneously, by the Migdal-Kadanoff approximation on the ... -
SPINAL: scalable protein interaction network alignment
(Oxford University Press, 2013)Motivation: Given protein-protein interaction (PPI) networks of a pair of species a pairwise global alignment corresponds to a one-to-one mapping between their proteins. Based on the presupposition that such a mapping ... -
Spline based channel estimation for STBC-SM systems over fast-varying rician fading channels
(Institute of Electrical and Electronics Engineers Inc., 2015)In the STBC-SM systems, the information is carried both by STBC symbols and indices of the transmit antennas from which these symbols are transmitted. Channel estimation is a critical process at the receiver during the ... -
Spline interpolation based channel estimation for ACO-OFDM over visible light channels
(Institute of Electrical and Electronics Engineers Inc., 2016)Visible light communication has been considered one of promising candidate technology to solve performance limitation due to bandwidth shortage at radio frequency (RF) band. In VLC system, the visible light is used not ... -
Spontaneous Past and Future Thinking About the COVID-19 Pandemic Across 14 Countries: Effects of Individual and Country-Level COVID-19 Impact Indicators
(Amer Psychological Assoc, 2022)In 2020, the world was amid a global health crisis-the COVID-19 pandemic. Nations had varying levels of morbidity and mortality and adopted different measures to prevent the spread of infection. Effects of the pandemic on ... -
Spontaneous ureteral rupture: Is immediate surgical intervention always necessary? Presentation of four cases and review of the literature
(Mary Ann Liebert Inc Publ, 2002)Purpose: We report our experience with spontaneous ureteral rupture (SUR) managed conservatively. Case Reports: Data on three men and one woman 53 to 89 years old (mean age 73) with SUR were retrospectively evaluated. The ... -
Squaring the Circle: The EU's Operational Impact in the Black Sea Region
(Routledge Journals Taylor & Francis Ltd, 2014)The aim of this paper is to explain the flux in the European Union (EU) policies towards the Black Sea region with a particular comparative focus on the impact of the EU's operations in the South Caucasus and the EU Border ... -
The stability constants of the rare earth complexes with trimetaphosphoric acid
(Soc Chimica Italiana, 2001)The stability constants of the complexes formed between the rare earth metal ions and the anion of trimetaphosphoric acid have been determined at a temperature of 20 degreesC and an ionic strength of mu =0.1 by the ... -
Stabilized cut discontinuous galerkin methods for advection-reaction problems
(Society for Industrial and Applied Mathematics Publications, 2020)We develop novel stabilized cut discontinuous Galerkin methods for advection-reaction problems. The domain of interest is embedded into a structured, unfitted background mesh in \BbbR d where the domain boundary can cut ... -
The stage: a space for queer subjectification in contemporary Turkey
(Routledge Journals Taylor & Francis Ltd, 2012)This article focuses on the role of the stage in complex modes of gender performativity in the work of three Turkish performers: Zeki Muren (1931-1996) Bulent Ersoy (b. 1952) and Seyfi Dursunoglu (b. 1932) a.k.a. Huysuz ... -
The stakes of the Ukrainian crisis in the Black Sea
(Institut de Relations Internationales et Strategiques, 2014)Among the most significant security concerns involving a confrontation between the Euro-Atlantic community and Russia since 1991, the Ukrainian crisis seems to reveal a greater geopolitical game, which cannot be understood ... -
State autonomy and neoliberal transition: A case study Turkey: 1980-2001
