Research ArticleOpen accessAll words, across the recordStudents’ Voices about Learning with TechnologyRuth Geer, Trudy-Ann SweeneyProblem statement: This study argues for the inclusion of student voice as a valid means of identifying 21st century pedagogical approaches to learning. Today’s students are increasingly living and thriving in a digital world and have a new “digital vernacular” which leads to differences in the way students think about learning. Approach: In Australia many students are already immersed in … …Journal of Social Sciences, Vol. 8, Issue 2 · 26 Mar 2012 · 11,679 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBluetooth Wireless Monitoring, Managing and Control for Inter Vehicle in Vehicular Ad-Hoc NetworksHelia Mamdouhi, Sabira Khatun, Javad ZarrinProblem statement: The car users expect more and more accessories available in their cars, but the accessories available needed manage by driver manually and not properly manage by smart system. All these accessories are able to control by user manually using different and standalone controllers. Besides, the controller itself uses RF technology which is not existed in mobile devices. So … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 8,978 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTheoretical and Simulation Approaches for Studying Compensation Strategies of Nonlinear Effects Digital Lightwave Links Using DWDM TechnologyJ. Bel Hadj TaharNowadays, techniques for education are based on the combination of theoretical formulas, experimental measurement and simulation approaches. Theoretical analysis, experimental and simulation approaches based educations allow developing simple and non expensive tools for the aim of studying complex problems in optical network communication. Theoretical formulas, used to describe the non linear effects on digital lightwave links, may by simplified with … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,700 accessesView PDFCite
