Research ArticleOpen accessIn the abstractAn Examination of Teaching Behaviors and Learning Activities in Physical Education Class Settings Taught by Three Different Levels of TeachersHoward Z. Zeng, Raymond W. Leung, Michael HipscherProblem statement: To be an accredited teacher education program, physical education teacher education (PETE) programs must fulfill the national standards established by the National Association for Sport and Physical Education (NASPE). In order to meet the standards, a PETE program needs to have the cooperation of the following three levels of instructors: Specialist Teachers (STs), Inservice Teachers (ITs) and Preservice … …Journal of Social Sciences, Vol. 6, Issue 1 · 31 Mar 2010 · 8,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractMachine Translation of Noun Phrases from Arabic to English Using Transfer-Based ApproachOmar Shirko, Nazlia Omar, Haslina Arshad, Mohammed AlbaredProblem statement: Any Arabic to English Machine Translation (MT) system should be capable of dealing with word order which Arabic exhibits. This poses a significant challenge to MT due to the vast number of ways to express the same sentence in Arabic. The ordering features are very important and should be carefully applied to ensure the generation of sentence in … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 8,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Comparison between Unconfined and Confined Condition of Foamed Concrete Under Uni-Axial Compressive LoadMohd Zairul Affindy Abdul Rahman, Ahmad Mujahid Ahmad Zaidi, Ismail Abdul RahmanProblem statement: Foamed concrete has become most commercial material in construction industry. People in industries were come out with the new mix design of foamed concrete to meet the specification and the requirements needed. Approach: This is because foamed concrete has the possibility as alternative of lightweight concrete for producing intermediate strength capabilities with excellent thermal insulation, freeze-thaw resistance, high-impact … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,637 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Pb(II) on Spent Leaves of Green and Black TeaAntonio Zuorro, Roberto LavecchiaProblem statement: In recent years much attention has been focused on the use of biomass residues as low-cost adsorbents for the removal of heavy metal ions from contaminated waters. Spent tea leaves, an abundantly available material that is currently disposed of as a solid waste, are potentially suitable for such applications. Approach: To provide some information on the adsorption properties … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 9,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Free Educational Java Framework for Graph AlgorithmsGianluca Costa, Claudia D’Ambrosio, Silvano MartelloProblem statement: In the teaching of graph theory algorithms it is important that students can experiment them on numerical instances in order to fully understand their logical meaning and to learn how they can be implemented. Approach: We developed an open source Java framework to help students in their approach to the study of graph algorithms. The framework was implemented … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,397 accessesView PDFCite
