Research ArticleOpen accessIn the abstractThe Coordinated Scheduling Support System of Production and DeliveryMing-Feng Yang, Yi LinProblem statement: Traditional scheduling models which only address the sequence of jobs to be processed at the production stage under some criteria are no longer suitable and should be extended to cope with the distribution stage after production. In a rapidly changing environment, competition among enterprises has a tendency to turn towards competing between supply chain systems instead of competing … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 6,798 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Information Overload on Brazilian E-ConsumersRafael Lucian, Salomão Alencar de FariasProblem statement: E-commerce is a reality; Companies must consider this media as an important trade channel without distances between products and consumers. A key issue of e-commerce is how companies are disclosing information to its customers. This study aims to measure if there is relationship between the information overload in the virtual environment and the response of satisfaction and confusion … …American Journal of Economics and Business Administration, Vol. 1, Issue 1 · 31 Mar 2009 · 7,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiodiesel Fuel Production from Algae as Renewable EnergyA.B.M. Sharif Hossain, Aishah Salleh, Amru Nasrulhaq Boyce et al.Biodiesel is biodegradable, less CO2 and NOx emissions. Continuous use of petroleum sourced fuels is now widely recognized as unsustainable because of depleting supplies and the contribution of these fuels to the accumulation of carbon dioxide in the environment. Renewable, carbon neutral, transport fuels are necessary for environmental and economic sustainability. Algae have emerged as one of the most promising … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 32,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractInclusion Identification by Inverse Application of Boundary Element Method, Genetic Algorithm and Conjugate Gradient MethodMahmud Khodadad, Mohsen Dashti ArdakaniCharacterization of the interior of an inhomogeneous body using displacement measurements obtained by conducting a simple tension test was investigated. A homogeneous elastic solid body is assumed to have another solid body with arbitrary shape hidden inside it. The shape and physical properties of this inclusion were unknown. The Boundary Element Method (BEM) coupled with a mete heuristic Genetic Algorithm … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 6,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation Of Polymeric Compound Cross Section SpringsMayas Al-Mahasne, Tareq A. Abu ShreehahThis paper presents an experimental investigation of the characteristic of the compound cross section springs on models made from polymeric materials (organic glass). Two constructive variants of the compound spring sections were specified with the help of criteria of similarity. The criterion of similarity of natural and model springs was determined by the simulation method at particular spring deflection. The … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 6,755 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification, Characterization and Quantification of Elastomeric/Plastomeric Waste for Sustainable Waste MinimizationKajal Yadav, Sangita, A. ChandraThe present study focuses on the importance of characterization of waste/post consumer polymers. In recent years sophisticated instrumental techniques played an important role in identification and characterization of polymers. Advances in computer techniques have been combined with analytical instruments to give analytical speed, resolution and minimal sample requirements unimagined a few years ago. The present study deals with the development … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,056 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPhysical and Geometrical Effects on the Vibratory Pattern of a Pipe Carrying Fluid FlowDahmane Mouloud, Samir Zahaf, Mawhoub Soubih et al.In this research, the first natural frequencies and critical velocities of a fluid flow-conveying pipe are obtained with finite element method. By discretizing the structure wall and fluid flow, starting from beam type with two degrees of freedom per node. We determine the equation of motion from the fluid-structure coupling using Lagrange energy principle. Parameters frequencies and critical velocity of … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 22 Oct 2020 · 11,396 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIsolation and Physical Characterization of Hydrophobin-Like Proteins (HLP) from Aerial Conidia of Metarhizium Anisopliae Var. AnisopliaeD. S.B. Kiong, Choon Fah J. Bong, P. J.H. KingThe aim of this study was to isolate and physically characterized Hyrophobin-Like Proteins (HLP) from the aerial conidia of two local isolates of Metarhizium anisopliae var. anisopliae, namely, TA and LR2. The protein samples were isolated based on their insolubility in hot Sodium Dodecyl Sulfate (SDS). The SDS-insoluble proteins were then purified in cold 98% formic acid and performic acid. … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 2 · 29 Jan 2015 · 7,776 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSIMULTANEOUS OPTIMISATION OF DRYING PARAMETERS OF CERAMIC BODIESSalah Mahmoudi, Ezzeddine Srasra, Fouad ZargouniThis study deals with the mineralogical, physico-chemical and geotechnical analyses of representative Aptian clays in the north-east of Tunisia. X-ray diffraction reveals a predominance of illite (50-60 wt.%) associated to kaolinite and interstratified illite/smectite. The accessory minerals detected in raw materials are quartz, calcite and Na-feldspar. The average amounts of silica, alumina and alkalis are 52, 20 and 3.5 wt.%, … …Current Research in Geoscience, Vol. 4, Issue 1 · 1 Jul 2014 · 6,991 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordApplying the Holistic Approach to the Physical Sciences and Engineering SystemsJoseph Z. Ben-AsherThe holistic approach is applied to several examples from the field of physics, engineering and systems engineering and its benefits are demonstrated. In all examples a holistic picture is used and studied while ignoring the various details of the discussed problems. Optimal control and optimal estimation approachs are used in the engineering examples. The results show that the holistic approach … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 6,912 accessesView PDFCite
