Room Acoustic Modelling of a Reverberation Chamber
(German Acoustical Society (DEGA), 2016)This paper aims at comparing measured broadband reverberation time values in the reverberation chamber of Scientific and Technological Research Council of Turkey - National Metrology Institute (TUBITAK-UME) in Gebze Turkey ... -
Nearest Fixed Clustering Algorithm (NFCA) for Wireless Sensor Networks
(Institute of Electrical and Electronics Engineers Inc., 2016)The objective of reducing energy consumption at the sensor nodes has become a key research area for wireless sensor networks (WSNs) in recent years. With the steady increase in the cost of energy the existing algorithms ... -
Transitional Butterworth-Chebyshev Filters
(IEEE, 2019)Filters which are studied in this paper have properties that lie between those of the Butterworth and Chebyshev filters. So it is appropriate to call this kind of filters as transitional Butterworth-Chebyshev filters. In ... -
Channel estimation for visible light communications using neural networks
(Institute of Electrical and Electronics Engineers Inc., 2016)Visible light communications (VLC) is an emerging field in technology and research. Estimating the channel taps is a major requirement for designing reliable communication systems. Due to the nonlinear characteristics of ... -
Noncoherent Ultra Wideband Wireless Sensor Networks for Primary User Detection
(IEEE Computer Society, 2016)As a result of increasing demand for new technologies unlicensed usage of available spectrum has become very essential to provide an efficient usage of spectrum. For that reason sensor networks may be a reliable option to ... -
On Channel Estimation in DC Biased Optical OFDM Systems Over VLC Channels
(IEEE Computer Society, 2016)Visible Light Communication(VLC) has been considered as a potential access option for 5G wireless systems to solve performance limitation due to bandwidth shortage at radio frequency (RF) band. In (VLC) system illumination ... -

Determinants of corporate cash holdings: Firm level evidence from emerging markets
(Springer, 2017)The objective of this chapter is to investigate the factors affecting corporate cash holdings in five emerging markets namely Brazil Indonesia Mexico Russia and Turkey. The sample consists of 1991 firms listed on the major ... -
Disappearing history: Challenges of imagining Berlin after 1989
(Berghahn Books, 2017)[Abstract Not Available] -
The relationship between firm size and export sales: Sector or size what matters?
(Physica-Verlag, 2017)This paper examines the performance of export focused companies listed on the Borsa Istanbul trading in the emerging market of Turkey. Using the panel data of stock market prices (1995–2011) we study the performance of ... -
Whither developmental state in East Asia

Assessing changes in Turkish public opinion: Current trends and future prospects
(International Institute of Informatics and Systemics IIIS, 2017)It would be unfair underestimating the accumulated knowledge and efforts which target to assess public opinion on certain issues and put forward effective plans. However many of the research aiming to analyze public opinion ... -
Energy security and policy: Between bandwagoning and hedging
(Taylor & Francis, 2019)[Abstract Not Available] -
Assortment optimization with log-linear demand: Application at a Turkish grocery store
(Elsevier, 2019)In retail sector product variety increases faster than shelf spaces of retail stores where goods are presented to consumers. Hence assortment planning is an important task for sustained financial success of a retailer in ... -
A low-complexity time-domain MMSE channel estimator for space-time/frequency block-coded OFDM systems
(Hindawi Publishing Corporation, 2006)Focusing on transmit diversity orthogonal frequency-division multiplexing (OFDM) transmission through frequency-selective channels this paper pursues a channel estimation approach in time domain for both space-frequency ... -
Advanced signal processing algorithms for wireless communications
(Springer-Verlag Berlin, 2006)Traditional wireless technologies are not well suited to meet the extremely demanding requirements of providing the very high data rates with the ubiquity mobility and portability characteristic of cellular systems. Some ... -
Linear expansions for frequency selective channels in OFDM
(Elsevier GMBH Urban & Fischer Verlag, 2006)Modeling the frequency selective fading channels as random processes we employ a linear expansion based on the Karhumen-Loeve (KL) series representation involving a complete set of orthogonal deterministic vectors with a ... -
A systems software architecture for training neural fuzzy neural and genetic computational intelligent networks
(IEEE, 2006)A systems software architecture for training distributed neural fuzzy neural and genetic networks and their relevant information models have been developed. Principles of on-line architecture building training managing and ... -
Near field parameter estimation of moving sources with recursive expectation maximization algorithm
(IEEE, 2006)In this paper maximum likelihood (ML) estimator is proposed for the joint estimation of the direction of arrival (DOA) and range parameters of moving sources in the near-field of the antenna array. ML estimation algorithm ... -
Support vector machines based target tracking techniques
(IEEE, 2006)This paper addresses the problem of aplying powerful statistical pattern classification algorithms based on kernels to target tracking. Rather than directly adapting a recognizer we develop a localizer directly using the ...
