Research ArticleOpen accessIn the abstractA New Approach of Almost Periodic Lumped Elements Circuits by an Iterative Method Using Auxiliary SourcesMohamed Karim Azizi, Lassaad Latrach, Nathalie Raveu et al.Nowadays, met materials with lumped or distributed elements are emerging and it is necessary to develop new techniques based on the following principles. The approach should be global and have to be formulated according to the existing classic formulations. In fact, the Wave Concept Iterative Process (WCIP) is systematically used in such application. On the other hand, the periodic medium … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 5 Oct 2013 · 6,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplying a Just-in-Time Integrated Supply Chain Model with Inventory and Waste Reduction ConsiderationsLi-Hsing Ho, Wei-Feng KaoJust-In-Time (JIT) has been playing an important role in supply chain environments. Countless firms have been applying JIT in production to gain and maintain a competitive advantage. This study introduces an innovative model which integrates inventory and quality assurance in a JIT supply chain. This approach assumes that manufacturing will produce some defective items and those products will not influence … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 4 Jul 2013 · 6,994 accessesView PDFCite
Research ArticleOpen accessIn the abstractTwist Springback Measurement of Autonomous Underwater Vehicle Propeller Blade Based on Profile DeviationAhmad Baharuddin Abdullah, Mohd Sapuan Salit, Zahurin Samad et al.Geometrical defects that are attributable to springback are among the major defects induced by the sheet metal forming process. Such defects are critical for sections with varying thickness, such as Autonomous Underwater Vehicle (AUV) propeller blades. In this study, the springback in the twist-bending of an AA6061 propeller blade was quantified by comparing the targeted and manufactured profiles obtained using … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 31 May 2013 · 7,383 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon Functional Requirement Traceability Automation-an Mobile Multimedia ApproachM. Rajaram, J. SelvakumarRequirements Engineering (RE) is the area of software engineering that deals with the discovery and specification of the objectives for the system under development and the environment in which it is used including the human activities it supports. Requirement Elicitation is process of gathering requirements from stakeholders. Incorporating RE to identify non Functional Requirements (NFR) in early stages of design … …Journal of Computer Science, Vol. 8, Issue 11 · 7 Sep 2012 · 6,930 accessesView PDFCite
Research ArticleOpen accessIn the abstractDEVELOPMENT OF INSPECTION SYSTEM FOR CORROSION CRACK IN R.C. FOR SECOND TUNNEL LINING BY USING KNOWLEDGE-BASED SYSTEMYousif Abdulwahid Mansoor, ZhiQiang ZhangDuring the last two or three decades, incidence of failure of reinforced concrete structures has been seen widely for many reasons, such as increasing service loads and/or durability problems and the economic losses due to such failures are costly. Nowadays, the size and the form of repair and rehabilitation market are too large since there has been an increased emphasis … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 27 Aug 2012 · 7,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of UGT1A9 Genetic Polymorphisms between Chinese Han and Tibetan PopulationsWei Yan, Jian Cui, Yuewen Wang et al.Although various polymorphisms have been identified in the UGT1A9 gene in the main sorts of ethnic groups in the world, no investigations have been focused on the Chinese Tibetan populations and the comparison between Chinese Tibetan and Han populations to date. This study was designed to systematically compare genetic differences between the two populations. We investigated the functional regions of … …Current Research in Medicine, Vol. 3, Issue 2 · 23 Aug 2012 · 7,647 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstablishing an Adaptive Production-Procurement System with Markov Chain Approach Associated with 3C TheoryChun-Ta LinProblem statement: In this study, we classify the imperfect situations that the unreliability of production and the defective products might be incurred from production process into eight independently recurrent categories. Approach: With the property of recurrence of Markov chain, the limiting probability of each imperfect production category can be calculated through the transition probabilities matrix generated from these imperfect production … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,357 accessesView PDFCite
Research ArticleOpen accessIn the abstractDie Radius Affecting Sheet Metal Extrusion Quality for Fine Blanking ProcessChatkaew Suriyapha, Suthep Yiemchaiyaphum, Bopit BubphachotProblem statement: Sheet metal extrusion is a process in which the punch penetrates one surface of the sheet metal material to cause it to extrude and flow toward the outlet of the die. Therefore, the process can invent different thickness of sheet metal work piece. From these advantages on the sheet metal extrusion, nowadays, it is generally used in many … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrity Classification Algorithm of Images obtained from Impact Damaged Composite StructuresMahmoud Z. IskandaraniProblem statement: Many NDT systems used for damage detection in composites are difficult to apply to complex geometric structures, also, they are time-consuming. As a solution to the problems associated with NDT applications, an intelligent analysis system that supports a portable testing environment, which allowed various types of inputs and provided sufficient data regarding level of damage in a tested … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,972 accessesView PDFCite
