Research ArticleOpen accessIn the abstractA Review on Factors Impinges Computer Usage in EducationNaresh Kumar, Raduan Che Rose, Jeffrey Lawrence D’SilvaThe growing body of literature associated with educational computer use had examined numerous variables and interrelationships in order to gain a better understanding of computer beliefs and use of computers within education. Teachers' computer acceptance is an important factor to the successful use of computers in education. Thus it is significant to draw attention to the factors affecting teachers' computer … …Journal of Social Sciences, Vol. 4, Issue 2 · 30 Jun 2008 · 8,226 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeterministic Parallel Sorting Algorithm for 2-D Mesh of Connected ComputersHamed Al Rjoub, Arwa Zabian, Ahmad OdatSorting is one of the most important operations in database systems and its efficiency can influences drastically the overall system performance. To accelerate the performance of database systems, parallelism is applied to the execution of the data administration operations. We propose a new deterministic Parallel Sorting Algorithm (DPSA) that improves the performance of Quick sort in sorting an array of … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractVulnerability Assessment of Power System Using Radial Basis Function Neural Network and a New Feature Extraction MethodAhmed M.A. Haidar, Azah Mohamed, Aini HussainVulnerability assessment in power systems is important so as to determine how vulnerable a power system in case of any unforeseen catastrophic events.

Research ArticleOpen accessIn the abstractThe Design of ADAT: A Tool for Assessing Automata-Based AssignmentsZarina Shukur, Nurul Fatihah MohamedThis study describes the design of an automatic assessment system for assessing an automata-based assignment. Automata concept is taught in several undergraduate computing courses such as Theory of Computation, Automata and Formal Languages and Compilers. We take two elements into consideration when assessing the student's answers; static element and dynamic element. The static element involves the number of states (initial … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 7,013 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Complexity Paradigm: Implications for Information Systems and their Strategic PlanningIndranil MukherjeeThe complexity framework was employed to analyse Information Systems and the strategic planning process associated with them. We provided an overview of the theories of complexity and their significance. The salient features of strategic planning for information systems were discussed and the need for a new paradigm, viz. complexity was pointed out. The concept of Class of a Complex System … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 7,989 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Method of Deductive Logical Inference ProofsMaher A. Nabulsi, Ayman M. AbdallaA method of proof is presented and used in proving theorems in logic and set theory. Many commonly used methods of proof are rigid and not easy to apply in proving different theorems. This study deductively draws conclusions from rules of logical inference and then, it generalizes the deduction methods to be applied to logic and set theory. Then, it … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,479 accessesView PDFCite
Research ArticleOpen accessIn the abstractTraditional Aquaculture Practice at East Calcutta Wetland: The Safety AssessmentS. Raychaudhuri, M. Mishra, S. Salodkar et al.The current study is on East Calcutta Wetland (ECW) which is a model for multi-use resource recovery system with activities like pisciculture and agriculture. The entire city's soluble waste is disposed into the raw sewage canals which finally drains into the shallow, flat bottom fish ponds called Bheri. These sewage fed fisheries act simultaneously for the purification process like removal … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 9,442 accessesView PDFCite

Azizul Moqsud, Shigenori Hayashi, Yan Jun Du, Daisuke SuetsuguIn order to explore the thermal properties of the Ariake Sea mud and to find out the affecting factors which affect these values, a portable thermal properties analyzer was used. Thermal conductivity, thermal resistivity, thermal diffusivity and volumetric heat capacity of the mud samples collected from both the tidal flat and inside the deep sea were measured in the laboratory. … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 6,969 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Solar Radiation in High Energy Intensive of the World by PV SystemU. Ali RahomaSolar energy can be converted directly into electricity by means of solar cells. Solar cells currently cost around $3.50 per watt for crystalline cells and $2 per watt for thin-film wafers, which are less efficient but can be integrated into building materials. Industry analysts note that between 2000 and 2005, each doubling of cumulative production resulted in a price drop … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 9,685 accessesView PDFCite
