PAAm-kappa carrageenan composites: drying and swelling with various kappa carrageenan contents
(Polish Acad Sciences Inst Physics, 2012)
The purpose of this study is to discuss the role of kappa-carrageenan (kappa-car) in the drying and swelling of polyacrylamide (PAAm)-kappa-car composite. The fluorescence intensity of pyranine increased and decreased as ...
Assessing the importance of international tourism for the Turkish economy: a social accounting matrix analysis
(Elsevier Science, 2012)
The international tourism sector has grown rapidly in Turkey since the 1980s and Turkey ranks among the top ten countries in terms of tourist arrivals and receipts. Previous studies on international tourism in Turkey are ...
Nondata-aided joint channel estimation and equalization for OFDM systems in very rapidly varying mobile channels
(IEEE-INST Electrical Electronics Engineers Inc, 2012)
This paper is concerned with the challenging and timely problem of joint channel estimation and equalization for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very ...
Energy consumption and income in Chinese provinces: heterogeneous panel causality analysis
(Elsevier Science, 2012)
Recently energy production in China fell behind energy consumption. This poses important challenges for the rapidly growing Chinese economy. As a consequence the causal relationship between energy consumption and GDP is ...
The Only Thing We Have to Fear: Post 9/11 Institutionalization of In-security [Korkmamız gereken tek şey: 11 Eylül sonrasında güvensizliğin kurumsallaşması]
(Uluslararası İlişkiler Konseyi Derneği, 2012)
During the last decade billions of dollars have been spent to increase security measures in the United States. New institutions including a department for homeland security have been established new security tools have ...
Evaluating machine tool alternatives through modified TOPSIS and alpha-cut based fuzzy ANP
(Elsevier Science Bv, 2012)
The problem of machine tool selection among available alternatives has been critical issue for most companies in fast-growing markets for a long time. In the presence of many alternatives and selection criteria the problem ...
Growth kinetics of MPS-capped CdS quantum dots in self-assembled thin films
(Springer, 2012)
For this study we prepared colloidal CdS quantum dots using 3-mercaptopropyltrimethoxysilane as capping agent. Colloidal CdS quantum dots were directly deposited on glass substrates by a spin-coating process. Coated ...
An interactive memetic algorithm for production and manufacturing problems modelled as a multi-objective travelling salesman problem
(Taylor & Francis Ltd, 2012)
In this paper a preference-based interactive memetic random-key genetic algorithm (PIMRKGA) is developed and used to find (weakly) Pareto optimal solutions to manufacturing and production problems that can be modelled as ...
Bayesian compressive sensing for ultra-wideband channel models
(IEEE, 2012)
Considering the sparse structure of ultra-wideband (UWB) channels compressive sensing (CS) is suitable for UWB channel estimation. Among various implementations of CS the inclusion of Bayesian framework has shown potential ...
Power and rate adaptation for MQAM/OFDM systems under fast fading channels
(IEEE, 2012)
In this paper the effect of power and rate adaptation on the spectral efficiency of orthogonal frequency division multiplexing (OFDM) systems using M-ary quadrature amplitude modulation (MQAM) is investigated in the presence ...
