Research ArticleOpen accessIn the abstractImproving the Accuracy of Effort Estimation through Fuzzy Set Representation of SizeCh. Satyananda Reddy, KVSVN RajuProblem statement: The precision and reliability of the effort estimation is very important for the competitiveness of software companies. The uncertainty at the input level of the Constructive Cost Model (COCOMO) yields uncertainty at the output, which leads to gross estimation error in the effort estimation. Fuzzy logic-based cost estimation models are more appropriate when vague and imprecise information was … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,085 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparison the Proposed Probabilistic-Based Time-History and the Traditional PSHA ApproachA. NicknamThe main objective of this article is to demonstrate the ability of our technique in estimating the probabilistic-based time-history to be used in dynamic analysis of structures. The result of using our technique is compared with that of traditional approach proposed by Cornell (Cornell, 1968), in the form of response spectrum through a case study. Good agreement of the two … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 6,945 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExtension Mechanisms to Support Sustainable Agriculture in Iran ContextMohammad Sadegh AllahyariSustainable agriculture, as a managerial philosophy has risen to meet environmental, economic and social complications. Agricultural extension as a source of information plays an important role for the achievement of sustainable forms of agriculture. In fact, conventional extension system cannot accomplish sustainability in agriculture. The objective of the study was to identify the most appropriate mechanism to support dimensions and … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,738 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Storage Time and Temperature on Serum AnalytesAbdoljalal MarjaniInformation on the measured concentration of serum analytes during storage of serum samples is often incomplete and sometimes contradictory. The 10 analytes have not studied in this area in healthy subjects. The aim of present study was designed to determine the effect of storage time and temperature on the laboratory results of 10 analytes in sera from apparently healthy adult … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 8,870 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPerformance of Unequal Error Protection Using Maximum A- posteriori Probability Algorithm and Modified MAP in Additive White Gaussian Noise and Fading ChannelT. Gnanasekaran, K. DuraiswamyProblem statement: In this study we propose a method to improve the performance of Maximum A-Posteriori Probability Algorithm, which is used in turbo decoder. Previously the performance of turbo decoder is improved by means of scaling the channel reliability value. Approach: A modification in MAP algorithm proposed in this study, which achieves further improvement in forward error correction by means … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,686 accessesView PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the abstractUse of the Chi-square Test to Determine Significance of Cumulative Antibiogram DataRocco J. Perla, James CarifioAn important function of a hospital’s Infectious Disease and Pharmacy programs is to review and compare the most recent antibiogram with that of the previous year to determine if significant changes in antibiotic susceptibility results are noted and to communicate this information and its consequences to the medical staff. However, there are currently no formal analytical (decision-making) models in use … …American Journal of Infectious Diseases, Vol. 1, Issue 4 · 31 Dec 2005 · 7,279 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Efficient Approach to Hide Compressed Voice Data in Arabic Text using Kashida and "La"Sabeeka M. Al-Oun, Jehad Q. Odeh AlnihoudIn this research, we propose a new approach to increase the capacity and enhance the reliability of hiding voice data in Arabic text. Using Kashida to hide bits in Arabic text is one of the most promising approaches in steganography. Unfortunately, ignoring the original Kashida in the cover text may affect the results significantly and produce inaccurate results in the … …Journal of Computer Science, Vol. 13, Issue 3 · 28 Mar 2017 · 7,788 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDevelopment and Early Score Validation of the Malaysian Educator’s Information Technology Attitude Scale (MEITAS)Wong Su LuanThe purpose of this study was to develop and provide initial validation evidence for an instrument to measure educators’ attitudes toward IT. Data were collected from 817 participants comprising both pre and in-service teachers in four phases. Two separate factor analyses were conducted for the pre-service teacher data and in-service teacher data. Principle component analysis, with varimax rotation, suggested three … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,204 accessesView PDF Cite
