A cooperative communication approach to cognitive radio
(Işık Üniversitesi, 2011-09-12)Cognitive radio, whose main idea is to have intelligent devices utilize the linı- ited resources, such as frequency spectrum in wireless channels, is becoming a groundbreaking technology. The aim of this thesis is to apply ... -
Cooperative multiple access under energy harvesting constraints
(Institute of Electrical and Electronics Engineers Inc, 2015)We consider a cooperative multiple access channel (MAC) with two energy harvesting transmitters. The transmitters perform delay constrained transmission, i.e., every information block is encoded, transmitted and decoded ... -
A cooperative neural network control structure and its application for systems having dead-zone nonlinearities
(Springer International Publishing Ag, 2022-03)An adaptive control structure utilizing two feed-forward neural networks (NN) is proposed to deal with systems having unknown nonlinearities. One of the networks is trained to mimic the nonlinear system dynamics. Its ... -
Cooperative strategies and achievable rates for two user OFDMA channels
(IEEE-INST Electrical Electronics Engineers Inc, 2011-12)We propose three encoding strategies for a two user cooperative Orthogonal Frequency Division Multiple Access (OFDMA) system, based on block Markov superposition encoding (BMSE). We obtain the expressions for the resulting ... -
Cooperative strategies, achievable rates and resource allocation for OFDMA channels
(Işık Üniversitesi, 2011-07-28)The design of next generation wireless communication systems brings along new challenges, since the degrading factors such as fading and multi-user interference become harder to deal with as the number of users and the ... -
Cooperative two-stage network dea: a goal programming approach
(Işık University Press, 2019-01-05)In this study, we present a two-stage data envelopment analysis method dealing with efficiency evaluation of decision making units with network structure. The key point of the study is that the suggested model optimizes ... -
Coordination in building an observatory: A case study of Eastern Anatolian Observatory (DAG)
(SPIE-Int Soc Optical Engineering, 2018)Eastern Anatolian Observatory (DAG) is designed to build on one of the summits of Palandoken Mountains in Erzurum, Turkey, at an altitude of 3,151 meters. The building is under construction since 2015 and expected to be ... -
CoP27'den Sonra, CoP28'den Önce: Türkiye'nin İklim Karnesi
(Işık Üniversitesi, 2023-06)Işık Üniversitesi, İktisadi, İdari ve Sosyal Bilimler Fakültesi, İktisat Bölümü tarafından aylık olarak yayınlanan Sürdürülebilir Ekonomik Sistemler (SES Lab) bülteni 2023 yılı 2. sayısıdır. -
The correlation of fast OSL component with the TL peak at 325 degrees C in quartz of various origins
(Elsevier Science BV, 2010-02)The fast component of the optically stimulated luminescence (OSL) signal in quartz is the basic tool for the optical dating. Its relation with the thermoluminescence (TL) glow-peak at about 325 degrees C is well established ... -
Corrigendum to “Detection of visual and frontoparietal network perfusion deficits in Parkinson’s disease dementia” [Eur. J. Radiol. 144 (2021) 109985]
(Elsevier Ireland Ltd, 2022-10-28)The authors would like to add the following grant support that was accidentally not included in the original article. Acknowledgements: This study was supported by TUBITAK 1001 project #115S219, Istanbul University Scientific ... -
Cost sensitive learning algorithms
(Işık Üniversitesi, 2008)This thesis studies the cost sensitive learning algorithms that calculate the class learning algorithms errors and costs. Data mining is the automated extraction of hidden predictive information from databases that can be ... -
Cost-conscious comparison of supervised learning algorithms over multiple data sets
(Elsevier Sci Ltd, 2012-04)In the literature, there exist statistical tests to compare supervised learning algorithms on multiple data sets in terms of accuracy but they do not always generate an ordering. We propose Multi(2)Test, a generalization ... -
Cost-effective fault diagnosis of a multi-component dynamic system under corrective maintenance
(Elsevier Ltd, 2021-04)Maintenance planning and execution are challenging tasks for every system with complex structure. Interdependent nature of the components that builds up the system may have significant effect on system integrity. While ... -
A cost-efficient bit-serial architecture for sub-pixel motion estimation of H.264/AVC
(IEEE Computer Soc, 2008)This paper presents a new VLSI architecture for sub-pixel motion estimation in H.264/AVC encoder. It is based on an interpolation free algorithm that causes a high level reduction on memory requirement, hardware resources ... -

Countering insurgency: Turkey's policy toward the PKK's transnational dynamics in Europe
(Routledge Journals, Taylor & Francis Ltd, 2018-01-02)Insurgents often develop international connections and benefit from external assistance from a variety of sources. Support from diaspora communities has long been considered one of the critical external factors in the ... -
Coupled influence of content, gradation and shape characteristics of silts on static liquefaction of loose silty sands
(Elsevier Sci Ltd, 2017-10)Static liquefaction is a challenging problem of geotechnical engineering as its consequences are generally catastrophic when they occur on site. Previous laboratory studies focused on various factors that could influence ... -
Coupled quintic nonlinear Schrodinger equations in a generalized elastic solid
(IOP Publishing Ltd, 2004-10-08)In the present study, the nonlinear modulation of transverse waves propagating in a cubically nonlinear dispersive elastic medium is studied using a multiscale expansion of wave solutions. It is found that the propagation ... -
