Research ArticleOpen accessEvery word in the titleHigh-Speed for Data Transmission in GSM Networks Based on Cognitive RadioAl Smadi Takialddin, Kalid Al Smadi, Orayb O. AL-SmadiThis paper mainly studies data transmission DT rate in the modern communication systems. Increasing the need to improve the sensitivity of the control systems to detect low signals weak capacity density in view of the increasing communications systems new radio that use the capacity is decreasing and the scope of the taking of spaciousness and frequencies are on the rise. … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 3 Feb 2017 · 9,083 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCognitive Mechanism of Metaphorization in Zoological TermsZifa Kakbaevna Temirgazina, Uldanai Maksutovna Bakhtikireeva, Vladimir Pavlovich Sinyachkin, Marzhan Kasymovna AkoshevaTerminology of any science, as a result of verbalized scientific expertise, is formed in conjunction with the ordinary consciousness of native speakers. Metaphor in a particular scientific zoological discourse in the Russian and Kazakh languages has not become the object of researchers' attention yet. The comparison of the results of the cognitive mechanism of analogy in the zoological discourse in … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 13 Dec 2016 · 7,538 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCognitively Inspired Algorithm for Imprecise NavigationMelissa Shahrom, Zalilah Abd AzizThis paper presents an algorithm, namely the private navigation algorithm. The aim of this algorithm is to bridge the gap between high quality navigation services and low quality of location information or imprecise data. Generally, the imprecision is due to the poor positioning technology and the algorithms use to protect location privacy. The benefits of the algorithm are at least … …Journal of Computer Science, Vol. 12, Issue 6 · 14 Jul 2016 · 7,097 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSecondary User Sensing Time Optimization in Sensing-Transmission Scheduling for Dynamic Spectrum Access in Cognitive RadioInderdeep Kaur Aulakh, Renu VigThe constraint of limited frequency spectrum for wireless communication is very daunting. The radio spectrum licensed to permanent users is wasted at times when not used continuously. Cognitive radio technology involves a change in regulation of radio spectrum. In cognitive radio networks a secondary user network is designed for efficiently using gaps in spectrum and not causing at the same … …Journal of Computer Science, Vol. 11, Issue 8 · 5 Nov 2015 · 7,343 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRealizing the Impact of Cognitive Dissonance in Predicting Consumer BehaviourAkhilesh Chandra Pandey, Mohit JamwalConsumer psychology has always been the centre of concern for the marketers from the old time and understanding the underlying aspects leads to effective decision making. The present study elicits the concept of post purchase cognitive dissonance in the consumers and embraces its implications in studying the consumer behaviour. A survey was conducted and well framed questionnaire was constructed covering … …Journal of Social Sciences, Vol. 12, Issue 1 · 1 Nov 2015 · 9,134 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRadiation-Induced Cognitive Dysfunction After Different Schemes of Fractionated Whole Brain IrradiationZorkina Yana Alexandrovna, Zubkov Eugene Andreevich, Yusubalieva Gaukhar Maratovna et al.Radiation-induced cognitive dysfunction is a serious complication of radiation therapy. In humans, numerous cases of radiation damage have been recorded after irradiation for therapeutic purposes. The degree of cognitive dysfunctions and its dependence on biological effective doses should be tested in animal preclinical models to minimize radiation side effects. Fractionated whole brain irradiation was performed according to the following schemes: … …Neuroscience International, Vol. 5, Issue 2 · 14 Jan 2015 · 7,256 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHE IMPACT OF COGNITIVE TRUST AND E-WOM ON PURCHASE INTENTION IN C2C E-COMMERCE SITEIka Alfina, Joni Ero, Achmad Nizar Hidayanto, Muhammad Rifki ShihabIn the last few years, the number of Internet users in Indonesia was growing rapidly as many people started to use e-commerce sites. Utilization of C2C e-commerce in particular has a risk that may reduce people interest in online shopping. Of the many factors that may influence online shopping intention, trust becomes the key. This study built a model to … …Journal of Computer Science, Vol. 10, Issue 12 · 27 Dec 2014 · 10,306 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCOGNITIVE AGENTS BASED SECURITY SCHEME TO HANDLE ROUTING LOOPS IN WIRELESS NETWORKSR. Kumar, G. KousalyaRouters in wireless networks are often prone to variety of attacks like a man in the middle, distributed denial of service, smurf, ping of death, routing loops, counting to infinity. Among all these attacks routing loop is the most common one and it have a harmful effect on network performance. In this study, we have proposed a novel cognitive agents … …Journal of Computer Science, Vol. 10, Issue 9 · 19 Apr 2014 · 6,717 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSecond-Order Statistical Approach for Digital Modulation Scheme Classification in Cognitive Radio Using Support Vector Machine and K-Nearest Neighbor ClassifierS. Ravi, R. KannanCognitive radio systems require detection of different signals for communication. In this study, an approach for multiclass signal classification based on second-order statistical feature is proposed. The proposed system is designed to recognize three different digital modulation schemes such as PAM, 32QAM and 64QAM. The signal classification is achieved by extracting the 2nd order cumulants of the real and imaginary … …Journal of Computer Science, Vol. 9, Issue 2 · 11 Apr 2013 · 6,732 accessesView PDFCite
