For the conception of this system, we stated with the assumption that the content of distance teaching is not just to put online the content used for classroom teaching. In addition to the classical … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,761 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 · 7,593 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Biology of p21Waf1/Cip1 - Review PaperRenald A. Blundellp21WAF1/Cip1 belongs to the Cip/Kip family of cyclin kinase inhibitors (CKI) (p21Waf1/Cip1, p27Kip1, p57Kip1). p21Waf1/Cip1 was first described as a potent and universal inhibitor of cyclin-dependent kinases (Cdks). Two forms of functionally active p21 has been localized and described: a nuclear and a cytoplasmic forms. In this paper the structures of p21 has been described and as well as it … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 1 · 31 Mar 2006 · 7,018 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Development of Sensor Based Traffic Light SystemA. Albagul, M. Hrairi, Wahyudi, M. F. HidayathullahThe main object of this study was to design and implement a suitable algorithm and its simulation for an intelligent traffic signal simulator. The system developed is able to sense the presence or absence of vehicles within certain range by setting the appropriate duration for the traffic signals to react accordingly. By employing mathematical functions to calculate the appropriate timing … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 6 Mar 2006 · 8,868 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Recipe Based Service Composition in Ubiquitous Smart SpacesJunaid A. Chowdary, Seung-Kyu Park, Suk-Kyo HongWe present a recipe based service composition scheme in smart spaces. We discuss real time problems of highly synchronized and user customizable processes with the help of an example. On-the-fly Quality of Service (QoS) shows up as a major issue in such environment. Furthermore the QoS of a dynamically composed service depends upon the aggregate QoS of its developing components. … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractJBOOM: Java Based Object Oriented Model of Software Configuration ManagementBhavya Mehta, S. K. MuttooMost of the present Software Configuration Management systems deal with version and configurations in the form of files and directories, the need today is to have a Software Configuration Management system that handles versions and configurations directly in terms of functions (program module). A major objective of this research is the use of Java in the Software Configuration Management systems. … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,892 accessesView PDFCite
Research ArticleOpen accessIn the abstractStability of Non-Neutral and Neutral Dynamic Switched Systems Subject to Internal DelaysM. De la Sen, J. L. Malaina, A. Gallego, J. C. SotoThis study deals with the quadratic stability and linear state-feedback and output-feedback stabilization of switched delayed linear dynamic systems with, in general, a finite number of non commensurate constant internal point delays. The results are obtained based on Lyapunov’s stability analysis via appropriate Krasovsky-Lyapunov’s functionals and the related stability study is performed to obtain both delay independent and delay dependent … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,723 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlow of Dividends under a Constant Force of InterestJuma Kasozi, Jostein PaulsenThis study addresses the issue of maximization of dividends of an insurer whose portfolio is exposed to insurance risk. The insurance risk arises from the classical surplus process commonly known as the Cramér-Lundberg model in the insurance literature. To enhance his financial base, the insurer invests in a risk free asset whose price dynamics are governed by a constant force … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,388 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalyzing Concept Maps as an Assessment (Evaluation) Tool in Teaching MathematicsAhmet S. OzdemirIn this research concept mapping has been used as a testing instrument. In our country's education system, the relationship between the scores which are given to concept maps and the scores which are given to traditional written exams and multiple choice examinations in teaching mathematics, has been analyzed. Especially the examinations about functions, numbers, exponent numbers, rooted numbers and absolute … …Journal of Social Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,407 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroduction to the Besov Spaces and Triebel-Lizorkin Spaces for Hermite and Laguerre expansions and some applicationsA. Iris, P. LopezWe introduced new definitions of Besov spaces and Triebel-Lizorkin spaces associated with multidimensional Hermite expansions and multidimensional Laguerre expansions. We showed that the set of p-integrable functions is a Triebel-Lizorkin space with respect to the Gaussian measure and similarly, with respect to the probabilistic Gamma measure. Also, we showed that the Gaussian Sobolev spaces and Laguerre Sobolev spaces are Triebel-Lizorkin … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 7,588 accessesView PDFCite
