Research ArticleOpen accessEvery word in the titleAn Efficient Course Resolution Multiple-Receiver Approach for Reception of Slow Fading Signals in Digital Wireless Communication SystemsAshraf Mamdouh Aziz, Senior Member, IEEE et al.Multiple-receiver digital wireless communication systems employ several receivers and a digital central receiver with data fusion to reduce the effect of multipath fading problems. The multiple receiver observations are processed at individual receivers and sent to a digital central receiver. The digital central receiver fuses all the individual receiver data to form global data on which symbol was transmitted. In … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 7 Sep 2015 · 6,514 accessesView PDFCite
EditorialOpen accessEvery word in the titleRECENT TRENDS AND CHALLENGES OF ENERGY EFFICIENT AND SUSTAINABLE BUILDINGSChiara BedonAccording to several studies (e.g., the Intergovernmental Panel on Climate Change (IPCC, 2014), the US Energy Information Administration (US EIA, 2014), warming of the climate system is unequivocal and mainly derives from greenhouse gas emissions due to human activities. Global Carbon Dioxide (CO2) emissions from fossil fuels, for example, are estimated to be 29% higher in 2035 than they were … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 11 Sep 2014 · 8,503 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMETADATA DRIVEN EFFICIENT KEY GENERATION AND DISTRIBUTION IN CLOUD SECURITYR. Anitha, Saswati MukherjeeWith rapid development of cloud computing to a greater extent IT industries outsource their sensitive data at cloud data storage location. To keep the stored data confidential against untrusted cloud service providers, a natural way is to store only encrypted data in the cloud severs and providing an efficient access control mechanism using a competent cipher key-Cmxn, which is becoming … …Journal of Computer Science, Vol. 10, Issue 10 · 12 May 2014 · 6,629 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEXTENDED-RANDOMIZED, EFFICIENT, DISTRIBUTED: A DYNAMIC DETECTION OF CLONE ATTACKS IN STATIC WIRELESS SENSOR NETWORKSC. Geetha, M. RamakrishnanA wireless sensor network is a collection of nodes organized in to a cooperative network. Each node consists of processing capability, multiple types of memory, a power source and actuators and sensors. This wireless sensor network is established in hostile and harsh environments like civil and military applications. This network is prone to various attacks. One of the major attack … …Journal of Computer Science, Vol. 10, Issue 10 · 6 May 2014 · 6,747 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEFFICIENT RANKED AND SECURE FILE RETRIEVAL IN CLOUD COMPUTINGJ. Jospin Jeya, E. KannanCloud computing facilitates extremely scalable services that can be consumed over internet. An important aspect of the cloud services is that user data are stored remotely in unknown machines in which users do not posses or manage. Since the data’s are stored remotely, we have to keep in mind that sensitive cloud data have to be encrypted before they are … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 3 Apr 2014 · 6,856 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA NOVEL ROBUST AND EFFICIENT TOOL FOR DETECTING HETEROSCEDASTICITYWei Xiong, Maozai TianOne of the greatest values of Quantile Regression (QR) is that it provides a good procedure in the sense that QR could be much more efficient and sometimes arbitrarily more efficient in recovering the mean function than the Least Squares (LS) even when without moment conditions. However, heteroscedasticity definitely causes conditional variances of parametric or nonparametric estimates of mean functions … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 21 Mar 2014 · 6,662 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAREA EFFICIENT DISTRIBUTED ARITHMETIC DISCRETE COSINE TRANSFORM USING MODIFIED WALLACE TREE MULTIPLIERR. P. Meenaakshi Sundari, R. Anita, V. VenkateshwaranIn this study by using the modified Wallace tree multiplier, an error compensated adder tree is constructed in order to round off truncation errors and to obtain high through put discrete cosine transform design. Peak Signal to Noise Ratio (PSNR) is met efficiently since modified Wallace Tree method is an efficient, hardware implementable digital circuit that multiplies two integers resulting … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 19 Dec 2013 · 7,335 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConditioned Slicing for Efficient Multiway Decision Graphs Model-CheckerSaad ElmansoriIntegrating formal verification techniques into the hardware design process provides the means to rigorously prove critical properties. However, most automatic verification techniques, such as model checking, are only effectively applicable to designs of limited sizes due to the state explosion problem. The Multiway Decision Graphs (MDG) method is an efficient method to define hardware designs into more abstract environments; however, … …Journal of Computer Science, Vol. 9, Issue 3 · 23 Apr 2013 · 6,374 accessesView PDFCite
