Research ArticleOpen accessIn the abstractA Novel Image Component Transmission Approach to Improve Image Quality and Energy Efficiency in Wireless Sensor NetworksWei Wang, Dongming Peng, Honggang Wang, Hamid SharifDue to resource constraints, digital image transmissions are a significant challenge for image sensor based Wireless Sensor Networks (WSN). In this paper, we propose a novel robust and energy-efficient scheme, called Image Component Transmission (ICT) in WSN by providing various levels of reliability during image transmissions. Different components in the embedded wavelet image bit stream are considered and essential components … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Scale to Measure SuperstitionMd. Mahfuzul Huque, Ataharul Huq ChowdhuryThe purpose of the study was to construct a scale to measure superstition in a rural setting. A total of 31 statements or items expressing superstition were collected through reviewing relevant literature, consultation with extension experts, social scientists, progressive farmers and local leaders Statements were carefully examined and edited as per the criteria of Edwards[1]. The statements were employed to … …Journal of Social Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 8,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistributed Clusterhead Architecture for Mobile Ad Hoc NetworksEmad Qaddoura, Wesam AlMobaideen, Ahmad OmariMobile Ad Hoc Network (MANET) consists of dynamic topology as nodes in the network are mobile, and connected via wireless links. The nodes are grouped in clusters for the purpose of routing. Nodes within the cluster communicate directly. However, nodes communicate outside the cluster through a centralized node that is called a clusterhead. An elected clusterhead is assigned for communication … …Journal of Computer Science, Vol. 2, Issue 7 · 31 Jul 2006 · 6,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractSingle-Electron Transistor (SET) Process and Device Simulation Using SYSNOPSYS TCAD ToolsUda Hashim, Amiza RasmiSimulation of semiconductor device fabrication and operation is important to the design and manufacture of integrated circuits because it provides insights into complex phenomena that cannot obtained through experimentation or simple analytic models. Process and device simulation is commonly using for the design of new very large scale integration (VLSI) devices and processes. Simulation programs serves as exploratory tools in … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 7,418 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Comparative Study of RSA Based Digital Signature AlgorithmsRamzi A. Haraty, A. N. El-Kassar, Bilal ShibaroA digital signature is a mechanism designed to allow secure communication through an insecure medium and can be traced in many applications where privacy is required. A digital signature is an electronic signature that can be used to authenticate the identity of the sender of a message or the signer of a document and possibly to ensure that the original … …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 7,432 accessesView PDFCite
Research ArticleOpen accessIn the abstractDFT Based Electrophilicity Index and QSAR study of Phenols as Anti Leukaemia AgentFarhan A. Pasha, Hemant K. Srivastava, Yakoob Beg, Pashupati P. singhDensity Functional reactivity indices based QSAR study of 49 phenol derivatives is presented in this paper. Two different models to describe the anti leukaemia activity of phenols have been made. First QSAR model includes molecular properties like molecular weight (Mw), hardness (η), chemical potential (μ), total energy, and electrophilicity index (ω). Various regression models have been made and regression quality … …American Journal of Immunology, Vol. 2, Issue 1 · 31 Mar 2006 · 7,587 accessesView PDFCite
