Research ArticleOpen accessIn the abstractOptical Investigation and Electronic Polarizability of Nd3+ Doped Soda-Lime-Silicate GlassesP. Chimalawong, J. Kaewkhao, P. LimsuwanProblem statement: This study researched on different physical and optical properties of Nd3+ doped soda-lime-silicate glass. The glasses containing Nd3+ in (65-x)SiO2: 25Na2O: 10CaO: xNd2O3 (where x = 0.0-5.0 mol%) had been prepared by melt-quenching method. The density and molar volume increase with increasing of Nd2O3 concentration due to increasing of Non Bridging Oxygen (NBOs) in glass matrix. The optical … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,149 accessesView PDFCite

Research ArticleOpen accessIn the abstractCooperative Sensing in Cognitive Radio Networks-Avoid Non-Perfect Reporting ChannelRania A. Mokhtar, Sabira Khatun, B. M. Ali, A. RamliProblem statement: Cognitive radio is a candidate technology for more efficient spectrum utilization systems based on opportunistic spectrum sharing. However, a common assumption regarding cognitive radios is that they are unlicensed spectrum users that should defer to (avoid interfering with) existing primary sources. Therefore effective sensing of primary users was a major focus of current research. Cooperative spectrum sensing had … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,734 accessesView PDFCite
