Research ArticleOpen accessIn the abstractIn vitro Antibacterial and Antifungal Activities of Nopalea cochenillifera Pad ExtractsR. Gomez-Flores, P. Tamez-Guerra, R. Tamez-Guerra et al.Effectiveness of botanical treatments has been recognized by many, but scientific validation on the beneficial use of plants is scarce. Nopalea pads are probably native to Mexico or Central America and are used for human consumption and for medicinal purposes. In this study, in vitro antibacterial and antifungal activities of fresh and dried Nopalea cochenillifera (NC) were investigated. MICs of … …American Journal of Infectious Diseases, Vol. 2, Issue 1 · 31 Mar 2006 · 7,744 accessesView PDFCite
Research ArticleOpen accessIn the abstractSplitting Technique Initialization in Local PCAAlok Sharma, Kuldip K. Paliwal, Godfrey C. OnwuboluThe local Principal Component Analysis (PCA) reduces linearly redundant components that may present in higher dimensional space. It deploys an initial guess technique which can be utilized when the distribution of a given multivariate data is known to the user. The problem in initialization arises when the distribution is not known. This study explores a technique that can be easily … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractParsimonious Var Models For Air Pollution Dynamic AnalysisFontanella lara, Granturco mariagraziaWe discuss a framework to obtain temporal predictions for an evolving spatial field regularly sampled in time at arbitrary spatial locations. Difficulties caused by large data sets and the modelling of complicated spatio-temporal interactions limit the effectiveness of traditional space-time statistical models. In this study, we propose the use of a flexible approach to deal with large and small time-scale … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractE-Learning under WebCTZ. A. Al-Khanjari, N. S. Kutti, H. A. RamadhanWith the introduction of Web-Based Instruction (WBI) the traditional classroom-based higher education could be made more effective form of instruction. But the studies have shown the negative results[1]. On the other hand the distance education has derived the direct benefit of WBI through extending classroom instruction in online to reach every remote student. However researchers have identified reasons for the … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Evaluation of Anti-Stripping Additives Mixing in Road Surface Pavement MaterialsTienfuan Kerh, Yu-Min Wang, Yulern LinMost road surfaces in Taiwan are paved with asphalt concrete but the phenomena of rutting, cracking and stripping of the pavement are frequently occurring due to the effects of traffic flow, thermal variation and water erosion caused by rain. In this study, a series of experiments were performed to examine the effectiveness of anti-stripping fillers, which include; rock flour, rock … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,911 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 abstractA Neural Network for Generating Adaptive LessonsHassina Seridi-Bouchelaghem, Toufik Sari, Mokhtar SellamiTraditional sequencing technology developed in the field of intelligent tutoring systems have not find an immediate place in large-scale Web-based education. This study investigates the use of computational intelligence for adaptive lesson generation in a distance learning environment over the Web. An approach for adaptive pedagogical hypermedia document generation is proposed and implemented in a prototype called KnowledgeClass. This approach … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 7,269 accessesView PDFCite
Research ArticleOpen accessIn the abstractFormation of Optimal Messages Path Delivery Within a Virtual Channel TechnologyH. Al-Bdour, K. KaabnehThis research study deals with the process of reduction and optimization of data transmission delays in mobile Internet networks during mobile subscriber transmission (SsS) to various coverage areas. The methods for information transmission in IP-networks and networks based on virtual channel technology are investigated. Throughout this research, special attention is given to the analysis of existing methods for channel reconfiguration … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,535 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Geo-Information Technology in the Study of Soil and Nutrients Loss by Water Erosion for three Different Land CoverMushtak T. Jabbar, C. A.I. Chong-Fa, Wang Tian-Wei, Shi Zhi-HuaThis research integrated the Revised Universal Soil Loss Equation (RUSLE) and the soil statistical analysis with RS and GIS techniques to quantify soil and nutrient loss risk. The Letianxi watershed, located in the southwest part of Hubei Province of China was taken as a case. A system was established for rating soil erodibility, slope length/gradient, rainfall erosivity and conservation practices. … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,790 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study for Allocating Resources in Research and Development Programs by Integrated Subjective and Objective Decision MethodChun-Chu LiuA decision model is developed to help managers select the most appropriate sequences of plans for product Research and Development (R and D) projects that have strict constraints on budget, time, and resources. In recent years, many organizations have changed from a discipline orientation to a focus on integrated programs and related outcomes. For decision-maker of these high-profile R and … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,268 accessesView PDFCite
