Research ArticleOpen accessIn the abstractVedas and the Development of Arithmetic and AlgebraGurudeo Anand TularamProblem statement: Algebra developed in three stages: rhetorical or prose algebra, syncopated or abbreviated algebra and symbolic algebra-known as “school algebra”. School algebra developed rather early in India and the literature now suggests that the first civilization to develop symbolic algebra was the Vedic Indians. Approach: Philosophical ideas of the time influenced the development of the decimal system and arithmetic … …Journal of Mathematics and Statistics, Vol. 6, Issue 4 · 31 Dec 2010 · 8,263 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarthquake Resistant Design of Reinforced Soil Structures Using Pseudo Static MethodB. Munwar Basha, G.L. Sivakumar BabuProblem statement: This study presented a method to evaluate the internal stability of reinforced soil structures against tension and pullout modes of failure using pseudo-static method for earthquake conditions. Approach: Using limit equilibrium method and assuming the failure surface to be logarithmic spiral, analysis was conducted to maintain internal stability against both tensile and pullout failure of the reinforcements. For … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,572 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Reliability and Productivity of an Aluminum Extruder by Implementation of Direct Torque Control TechnologyMazouz A. SalahatProblem statement: The linear motor drive is widely used in driving an extrusion puller in an aluminum extrusion industry. The main disadvantage of this drive is manual and step-wise torque control. This research was done to replace the linear motor drive by AC drive with direct torque control technology. Approach: Mathematical calculations were carried to select an AC drive which … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,267 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 2-Dimensional Model for the Transmission Dynamics of Schistosomiasis in the Human-Snail HostsG. Besigye-BafakiThe modes of transmission of schistosomiasis are considered. The transmission model is developed with an aim of establishing possible endemic equilibria within the community. Analysis of the model reveals that if the recovery rate β of human infectives and the death rate of snails δ are increased and if at the same time the contact rate κ of the human … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 6,506 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon Destructive Tests of Structural Bonds by Guided Ultrasonic Waves: Effect of a Surface Pretreatment or a Localized DefectValentina Vlasie, Martine RousseauThe aim of this study was to propose a non destructive method to test the mechanical quality of a bond aluminium/epoxy/aluminium. Thus, for each aluminium/epoxy interface, an intermediate interface modelling between a simple geometrical interface and an interphase (3D material medium), i.e. a 2D material medium. In order to describe the surface stresses, we introduce the surface free energy (the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,883 accessesView PDFCite

Case ReportOpen accessIn the abstractUsing Lean Six Sigma to Increase Efficiency of a Grain Receipt Process of a Brazilian Agroindustry CooperativeSeiti Moraes Sakumoto, Daiane Maria De Genaro Chiroli, Ana Caroline DzulinskiDue to the competitiveness of companies to increase market share, they have been more and more interested in topics related to cost reduction, process efficiency, new customers and continuous improvement. Considering this scenario, this study conducted analyses and implemented improvements using the Lean Six Sigma (LSS) methodology in a grain receipt process of a Brazilian agroindustrial cooperative to increase its … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 17 Jun 2019 · 7,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid, Hybrid Flexible and Fully Online Learning through Students' EyesDolapo Adeniji-Neill, Courtney Lee Weida, Anne MungaiHybrid and fully online studies and classrooms are no longer fringe elements of learning or knowledge acquisition; they have become integral part of learning in the 21st century. Like all modes and styles of learning, they depend on continuous research for best practices in order to remain relevant in terms of effectiveness and growth. This study is a collaboration between … …Journal of Social Sciences, Vol. 14, Issue 1 · 28 Sep 2018 · 8,273 accessesView PDFCite
Research ArticleOpen accessIn the abstractPresentation of the Mechanism in the CrossFlorian Ion Tiberiu Petrescu, Taher M. Abu-Lebdeh, Antonio ApicellaThe cross-machine has frequent uses in mechanical assemblies, automation, robotics and mechanisms with various uses. In the present paper we want to present this type of mechanism with its main, geometric, cinematic, strengths and propose its study in its possible use as an internal combustion engine. In this novelty, the mechanism will have two types of operation, one when operated … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 26 May 2018 · 8,064 accessesView PDFCite
Case ReportOpen accessIn the abstractProblematizing Fragmentation of Environment Governance in Cambodia -Revisiting Weber’s ‘Objectivity’-Taizo YokoyamaThis theoretical study problematizes fragmented policies and governances of environment in Cambodia, drawing on some case studies of decentralization policy. The analysis through extensive literature review ascribes the cause of fragmentation to international aid dependence, which allows scientists to intervene in developing governance reform and policy-making process under the name of Technical-Assistance. The nature of social science will be examined … …Journal of Social Sciences, Vol. 13, Issue 4 · 30 Nov 2017 · 7,798 accessesView PDFCite
