Multi-hop low energy fixed clustering algorithm (M-LEFCA) for WSNs
(Institute of Electrical and Electronics Engineers Inc., 2017)The limited battery supply of sensor nodes is one of the most important factors which restrict the lifetime of the wireless sensor networks (WSNs). As a consequence the wide deployment of WSNs in the recent years led to ... -
An analysis for the use of compressed sensing method in microwave imaging [Mikrodalga Görüntülemede Sıkıştırılmış Algılama Yönteminin Kullanımına Yönelik Bir Analiz]
(Institute of Electrical and Electronics Engineers Inc., 2017)One of the most important problems encountered in microwave imaging methods is intensive data processing traffic that occurs when high resolution and real time tracking is desired. Radar signals can be recovered without ... -
Multi-tenant architectures in the cloud: A systematic mapping study
(Institute of Electrical and Electronics Engineers Inc., 2017)Unlike traditional web applications cloud-based applications can provide services for large number of tenants using the same hardware and software by implementing multi-tenant architectures. 407 papers have been examined ... -
A novel hybrid approach for sentiment classification of TURKISH tweets for GSM operators
(North Atlantic University Union, 2018)The increase in the amount of content shared on social media makes it difficult to extract meaningful information from scientific studies. Accordingly in recent years researchers have been working extensively on sentiment ... -
A synthesis tool for the multiplierless realization of FIR-based multirate DSP systems
(IEEE, 2000)In this study a synthesis tool using a novel multirate folding technique which handles each FIR filter in a multirate DSP system as a single node is developed. A new architecture is presented for the multiplierless realization ... -
Zero-crossing based demodulation of minimum shift keying
(2003)Minimum shift keying (MSK) modulation has features such as constant envelope compact spectrum and good error performance which are all desirable in many digital applications including mobile radio. Numerous receiver ... -

A low-complexity KL expansion-based channel estimator for OFDM systems
(2005)This paper first proposes a computationally efficient pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorithm for OFDM systems in unknown wireless fading channels. The proposed approach employs ... -
Frequency selective fading channel estimation in OFDM systems using KL expansion
(2005)This paper proposes a computationally efficient linear minimum mean square error (MMSE) channel estimation algorithm based on KL series expansion for OFDM systems. Based on such expansion no matrix inversion is required ... -
The effects of higher-order approximations in a fluid-filled elastic tube with stenosis
(Verlag der Zeitschrift fur Naturforschung, 2006)Treating arteries as thin-walled prestressed elastic tubes with a narrowing (stenosis) and blood as an inviscid fluid we study the propagation of weakly nonlinear waves in such a fluid-filled elastic tube by employing the ... -
The effect of a bump in an elastic tube on wave propagation in a viscous fluid of variable viscosity
(Elsevier Science, 2007)In the present work treating the arteries as a thin walled prestressed elastic tube with a bump and the blood as a Newtonian fluid of variable viscosity we have studied the propagation of weakly nonlinear waves in such a ... -
Text area detection in digital documents images using textural features
(Springer, 2007)In this paper we propose a new texture-based method for extraction of text areas in a complex document image. Gabor filter motivated by the multi-channel filtering approach of Human Visual System (HVS) has been employed ... -
