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 · 7,405 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Total Productivity PCA Model for Assessment and Improvement of Electrical Manufacturing SystemsAli Azadeh, Farid GhaderiThis study presents a framework for assessment of electrical manufacturing systems based on a total machine productivity approach and multivariate analysis. Furthermore, the total model is developed by Principle Component Analysis (PCA) and validated and verified by Numerical Taxonomy (NT) and non-parametric correlation methods, namely, Spearman correlation experiment and Kendall Tau. To achieve the objectives of this study, a comprehensive … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,270 accessesView PDFCite
Research ArticleOpen accessIn the abstractAsynchronous NoC Router DesignSami Badrouchi, Abdelkrim Zitouni, Kholdoun Torki, Rached TourkiThe Quality of Service Network on Chip (QNoC) is the most perferment solution that provides low latency transfers and power efficient System on Chip (SoC) interconnect. This study presents an asynchronous NoC router, for use in 2-D mesh-connected networks. It comprises multiple interconnected input and output ports and dynamic arbitration mechanisms that resolve any output port conflicts based on the … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 7,414 accessesView PDFCite
Research ArticleOpen accessIn the abstractEdge Defection Prediction by Using Wavelet CompressionYas A.K. AlsultannyDigital image have been expanding in usage. The importance of image compression algorithms have been increased, to produce smaller file size with a lower computational requirement. The wavelet transform offers a natural decomposition of images at multiple resolutions, since the wavelet transform can decompose images into various multiresolution subbands, where the correlation exists. A novel technique for image compression by … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 7,287 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Flow in Agriculture: BangladeshM. S. Alam, M. R. Alam, K. K. IslamIn this paper, a qualitative energy flow analysis in Bangladesh agriculture has been made for a period from 1980-81 to 2000-01 to evaluate the impact of energy input to produce output. Human and animal muscle power and machinery energy for tillage operation, electricity and diesel energy for irrigation, fertilizer and pesticides energy for growth and protection are taken into account. … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 11,587 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Stability of a Certain Class of Linear Time-Varying SystemsM. De la SenThis study firstly considers the exponential stability of unforced linear systems of slowly time-varying dynamics. Possible switchings of the system structure to unstable dynamics during certain finite time intervals are admitted. The maintenance of global exponential stability does not necessarily require at most a finite number of switchings in the dynamics while infinitely many switches can also lead to stability. … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrade-GDP Nexus in Iran: An Application of the Autoregressive Distributed Lag (ARDL) ModelMosayeb Pahlavani, Ed Wilson, Andrew C. WorthingtonThis study employed annual time series data (1960-2003) and unit root tests with multiple breaks to determine the most likely times of structural breaks in major factors impacting on the trade-GDP nexus in Iran We found, inter alia, that the endogenously determined structural breaks coincided with important events in the Iranian economy, including the 1979 Islamic revolution and the outbreak … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 8,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociation of Oral Contraceptives and Abnormal Pap SmearSayedmohsen Sayednozadi, Mohammadreza Hassany, Mohammad Arash RamezaniTo assess the hypothesis that combined Oral Contraceptive (OCs) increase the risk of cervical neoplasia, we conducted a multicenter Case-Control study in Mashhad, the capital of Khorasan province. Seventy-eight women with moderate to severe dysplasia at Pap smear as case group and one hundred fifty nine women with normal Pap smear were selected as the control group for evaluation. The … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreased Production of Nitric Oxide Contributes to Renal Oxidative Stress in Endotoxemic RatBahar Tunçtan, Belma Korkmaz, Hatice Yıldırım et al.Overproduction of reactive oxygen and nitrogen species leads to oxidative stress and decreased total antioxidant capacity, which is responsible for high mortality from several diseases such as endotoxic shock. Nitric oxide (NO) produced by inducible NO synthase (iNOS) during endotoxemia is the major cause of vascular hyporeactivity, hypotension and multiple organ failure. In this study, we investigated whether increased production … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 8,638 accessesView PDFCite
Research ArticleOpen accessIn the abstractInduction of Caspase-dependant Apoptosis by Enterovirus 70 in Human Lens Epithelial SRA01/04 CellsDequan Chen, Chris Duggan, Donald E. Texada et al.Enterovirus 70 (EV70), an etiological agent of acute hemorrhagic conjunctivitis (AHC), induces apoptosis in human Chang’s conjunctival (HCC) cells. EV70 is also able to infect and replicate in some other human cells such as human lens epithelial SRA01/04 cells and U937 cells. EV70 infection was found to induce apoptosis in SRA01/04 cells. During EV70-induced apoptosis of SRA01/04 cells, the expression … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 6,636 accessesView PDFCite
