Research ArticleOpen accessIn the author namesTowards A Dynamic Object-Oriented Design Metric Plug-in FrameworkC. H. Loh, S. P. LeeProblem Statement: The evolution of software is made difficult by the need to integrate new features with all previously implemented features in software applications. Approach: present study introduced a general-purpose, platform-independent object-oriented design metric plug-in framework called jmetric intended to help building scalable, extendable object-oriented design metric plug-ins. jmetric seeks to address problem by providing the plug-in developer a structured … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,917 accessesView PDFCite
Research ArticleOpen accessIn the author namesPhysiochemical Properties of Sago Starch Modified by Acid Treatment in AlcoholP.H. Yiu, S.L. Loh, A. Rajan et al.Sago starch is usually chemically modified to overcome and improve the unstable properties of native sago starch during processing. In this study, sago starch was treated in hydrochloric acid in the presence of methanol, ethanol and 2-propanol at 450C for 1 hour. Granule size, granular structure and solubility of the modified starch were investigated. Results showed that recovery yields of … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 8,912 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Study of Residual Oils Recovered from Spent Bleaching Earth: Their Characteristics and ApplicationsLoh Soh Kheang, Cheng Sit Foon, Choo Yuen May, Ma Ah NganThis study described the extraction of residual oils of spent bleaching earth (SBE) from palm oil refining industry, the properties and applications of residual oils obtained there from. Residual oils of SBE (acid-activated, WAC and neutral, NC) were recovered via solvent and supercritical-fluid (SC-CO2) extraction. The yields of residual oils recovered from WAC were higher than those from NC using … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 9,235 accessesView PDFCite
Research ArticleOpen accessIn the author namesAn Efficient Resource Provisioning Technique in Inter-Cloud using Peer-to-Peer ApproachManbir Kaur, Kiranbir Kaur, Lohit KapoorResource discovery is the process of computing systems; it supports resource management and scheduling of applications. It searches for the apposite variety of resource that satisfies the user's requirements. Resource discovery in computing system is perplexing because of conventional centralized approaches and resilient availability of resources. This scenario becomes more complex in inter-clouds owing to the dynamism and heterogeneity of … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 24 May 2017 · 7,458 accessesView PDFCite
Research ArticleOpen accessIn the author namesCALCITONIN GENE-RELATED PEPTIDE IN SERUM AFTER SPONTANEOUS SUBARACHNOID HEMORRHAGEKarl-Michael Schebesch, Elisabeth Bruendl Andreas Hochreiter, Judith Scheitzach et al.Endogenous Calcitonin Gene-Related Peptide (CGRP) stored in perivascular nerve fibers around the cerebral arteries mediates vasodilation and regulates cerebral blood flow under physiological conditions. Increased levels of CGRP have been continually reported in patients with migraine, but the role of CGRP in the pathophysiology of Subarachnoid Hemorrhage (SAH) has not yet been sufficiently evaluated. Over 10 days, serum was prospectively … …Neuroscience International, Vol. 5, Issue 1 · 28 Jun 2014 · 7,594 accessesView PDFCite
Research ArticleOpen accessIn the author namesIntegrating Renewable and Nonrenewable Energies in Power Plant PlanningHabib H. Al-Ali, Yousef Saif, Ali Elkamel, Ali LohiProblem statement: Electricity can be generated from different type of technologies such as fossil and non-fossil power plants. Among these technologies, coal-fired power plants have been a major route for electricity generation. Recently, environmental constraints were imposed over the coal power plant operations in order to reduce their emissions. Besides, renewable energy power plants such as hydroelectric, wind, solar and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,811 accessesView PDFCite
Research ArticleOpen accessIn the author namesIntermittent Aeration in Biological Treatment of WastewaterH. Doan, A. LohiProblem statement: E-coating process is widely used to provide a protective coating layer on metal parts in the automotive and metal finishing industry. The wastewater from the coating process contains organic compounds that are used in the cleaning, pretreatment and coating steps. Organic pollutants can be removed biologically. In the aerobic biological treatment, water aeration accounts for a significant portion … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,139 accessesView PDFCite
Research ArticleOpen accessIn the author namesCrack Growth in Concrete Gravity Dams Based on Discrete Crack MethodA.R. Lohrasbi, R. AttarnejadSeepage is the most parameter in water management safety and in stable agricultural. This seepage is passed through the cracks that are present to some degree in hydraulic structures. They may exist as basic defects in the constituent materials or may be induced in construction or during service life. To avoid such failure in concrete dams, safety would be an … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,082 accessesView PDFCite
Research ArticleOpen accessIn the author namesWater Hammer Analysis by Characteristic MethodA.R. Lohrasbi, R. AttarnejadRapid changes in the velocity of fluid in closed conduits generate large pressure, which are transmitted through the system with the speed of sound. When the fluid medium is a liquid the pressure surges and related phenomena are described as water hammer. Water hammer is caused by normal operation of the system, such as valve opening or closure, pump starts … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 8,705 accessesView PDFCite
Research ArticleOpen accessIn the author namesOptimal Production Planning of Electricity from Coal-Fired Power Plant Networks under Environmental ConsiderationsHabib H. Al-Ali, Yousef Saif, Ali Elkamel, Ali LohiIn this study, electricity production from a network of coal power plants and under environmental constraints is considered. Several pollutants are incorporated into the decision planning process including nitrogen oxides (NOx), sulfur oxides (SOx) and mercury (Hg). A Nonconvex Mixed Integer Nonlinear Programming (MINLP) model was first developed to assist in the evaluation process. An exact linearization of the nonconvex … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Mar 2008 · 7,074 accessesView PDFCite
