Wavelet-based cognitive SCMA system for mmWave 5G communication networks
(Inst Engineering Technology-IET, 2017)
Fifth generation (5G) communication networks can achieve high spectral efficiency using sparse code multiple access (SCMA) scheme when large number of users are trying to transmit their data simultaneously. The sparsity ...
Epidemic models for phase transitions: application to a physical gel
(Taylor & Francis Ltd, 2017)
Carrageenan gels are characterized by reversible sol-gel and gel-sol transitions under cooling and heating processes and these transitions are approximated by generalized logistic growth curves. We express the transitions ...
High-pass/low-pass section design for 0 degrees-360 degrees lumped-element phase shifters via the real frequency technique
(TUBITAK Scientific & Technical Research Council Turkey, 2017)
In this paper an algorithm based on the real frequency technique (RFT) is proposed to design high-pass and low-pass sections of a 0 degrees-360 degrees wide range lumped-element phase shifter. The switching process however ...
A Novel Image Steganography Technique based on Similarity of Bits Pairs
(IEEE, 2017)
Steganography is one of the most important information hiding mechanism which can be used along with cryptography for providing adequate data security. The common Steganographic mediums used are text image audio and video ...
Characterization of MWCNT-TiO2 Qps and TiO2 QDs in self-assembled films
(Elsevier, 2017)
In this study the solution which includes TiO2 quantum dots (QDs) was mixed with the multi-wall carbon nanotubes (MWCNTs) to prepare MWCNT-TiO2 QDs composite films. The effect of microstructures on the structural and optical ...
A fuzzy AHP-PROMETHEE II approach for evaluation of solar power plant location alternatives in Turkey
(IOS Press, 2017)
Solar energy produced through a solar power plant is a freely available non-polluting renewable source of energy that reduces the greenhouse effect. Selecting the best location for a solar power plant among several location ...
The Effect of Energy Geopolitics on International Climate Change Initiatives
(Uluslararası İlişkiler Konseyi Derneği, 2017)
In this article in general the relationship between international climate change initiatives and energy geopolitics was analyzed and in particular the developments in energy geopolitics were investigated with a historical ...
A crude marriage: Iraq Turkey and the Kirkuk-Ceyhan oil pipeline
(Routledge Journals Taylor & Francis Ltd, 2017)
Since the discovery of oil at Kirkuk in northern Iraq oil has shaped relations between Iraq and Turkey as the former needed markets and export routes to the Mediterranean and the latter reliable sources of supply. This ...
Bayesian estimation of discrete-time cellular neural network coefficients
(TUBITAK Scientific & Technical Research Council Turkey, 2017)
A new method for finding the network coefficients of a discrete-time cellular neural network (DTCNN) is proposed. This new method uses a probabilistic approach that itself uses Bayesian learning to estimate the network ...
Broadband matching via reflection function optimization
(Wiley, 2017)
In this paper a practical approach is presented for designing broadband matching networks via reflection function optimization. In the proposed algorithm the input or output reflection function of the matching network is ...
