The effect of European and global uncertainty on stock returns of travel and leisure companies
(Sage Publications Ltd, 2019)
This article aims to evaluate the impact of economic policy uncertainty (EPU) on the STOXX Europe 600 Travel & Leisure Price Index by utilizing a monthly data set for 20 years through 1997-2016. It is found that both the ...
Improving Item-Based Recommendation Accuracy with User's Preferences on Apache Mahout
(IEEE, 2016)
Recommendation systems play a critical role in the Information Science application domain especially in e-commerce ecosystems. In almost all recommender systems statistical methods and machine learning techniques are used ...
Power and Rate Adaptation Based on CSI and Velocity Variation for OFDM Systems Under Doubly Selective Fading Channels
(IEEE-INST Electrical Electronics Engineers Inc, 2016)
In this paper a novel joint continuous power and rate adaptation scheme is proposed fordoubly selective fading channels in orthogonal frequency division multiplexing (OFDM) systems based on terminal velocity and perfect ...

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 ...
Traditional Folklore Forms in Temaşa-i Dünya ve Cefakar-u Cefakeş [Temaşa-i Dünya ve Cefakar-u Cefakeş´te Geleneksel Folklor Biçimleri]
(Milli Folklor Dergisi, 2016)
Temaşa-i Dünya ve Cefakâr u Cefakeş written by Evangelinos Misailidis in 1871-1872 has widely been considered to be an adaptation of the Greek novel O Polipathis (1839) and its originality has not been adequately emphasized ...
Branding cities in the age of social media: A comparative assessment of local government performance
(Springer International Publishing, 2015)
This chapter is a comparative study of how three local governments- Cape Town (South Africa) Philadelphia (Pennsylvania USA) and Myrtle Beach (South Carolina USA)-use social media platforms in their city branding attempts. ...
Optical OFDM with index modulation for visible light communications
(Institute of Electrical and Electronics Engineers Inc., 2015)
In this paper we propose optical orthogonal frequency division multiplexing with index modulation (O-OFDM-IM) for visible light communications (VLC) systems employing light emitting diodes (LEDs) and photodetectors (PDs). ...
