Research ArticleOpen accessIn the abstractMachining Performance Study on Metal Matrix Composites-A Response Surface Methodology ApproachA. Srinivasan, R. M. Arunachalam, S. Ramesh, J. S. SenthilkumaarProblem statement: Metal Matrix Composites (MMC) have become a leading material among composite materials and in particular, particle reinforced aluminum MMCs have received considerable attention due to their excellent engineering properties. These materials are known as the difficult-to-machine materials because of the hardness and abrasive nature of reinforcement element-like Alumina (Al2O3). Approach: In this study, an attempt has been made … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 15 Feb 2012 · 8,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Egyptian Smectitic Clay Deposits by Methylene Blue AdsorptionSalwa D. Abayazeed, Essam El-HinnawiProblem statement: The characterization of smectitic clays has been traditionally made using physical and chemical methods which are time-consuming and require costly equipment. Adsorption of methylene blue by these clays has been introduced as a quick and cheap method for the estimation of cation exchange capacity and surface area. Therefore, the aim of the present study was to test the … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 11 Oct 2011 · 7,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach to Head positioning using Fixed Center Interpolation Net with Weight Elimination AlgorithmMahmoud Zaki IskandaraniA reliable algorithm for head movements inside a vehicle is designed. The proposed algorithm allowed the adjustment of basic functions such as indicators, mirrors and reverse lights based on the driver final head position. The algorithm system mapped a predefined coordinates for driver’s head that resulted in a computable geometry via a sensory system which is fed to the vehicle … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,309 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Dynamics Studies of Human β-GlucuronidaseIbrahim Ali Noorbatcha, Ayesha Masrur Khan, Hamzah Mohd SallehProblem statement: The enzyme β-glucuronidase is being used as a reporter molecule in the area of genetic engineering, as a component of prodrug therapy in cancer treatment and in the scouring process of cotton fabrics. However, a detailed understanding of the factors responsible for the stability and the activity of this enzyme is still not available. Molecular Dynamics (MD) simulations … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,619 accessesView PDFCite
Research ArticleOpen accessIn the abstractNoise Control Using Coconut Coir Fiber Sound Absorber with Porous Layer Backing and Perforated PanelRozli Zulkifli, Zulkarnain, Mohd Jailani Mohd NorProblem statement: Noise control was one of the major requirements to improve the living environment. One of the methods to do that is provided by sound absorber. Commonly, multi-layer sound absorbers are applied to absorb broadband noise that was composed of perforated plates, air space and porous material. However, multi-layers sound absorbers effectiveness depends on their construction. This study was … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 14,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Time Variation on the Wear Sliding Behavior of CompositesWafaa M. Salih, Sanaa M. Salih, Myada M. SalihComposites materials are widely used in all industries all over the world, replacing many other engineering materials. Reasons for such popularity are many, among such, are their physical and mechanical properties in addition to the simplicity of their manufacturing processes. Machine elements that are made of polymeric materials are usually exposed to different causes of failure such as wear. The … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 6,984 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent Estimation of Compressive Strength of the Pavement Layers Stabilized by the Combination of Bitumen Emulsion and CementMehrdad Aryafar, Abdoul R. Ghotbi, Mehdi Aryafar, Amin AvaeiThe Application of the different types of additive materials such as lime, cement bitumen and the combination of them are considered as a main issue by the relating experts. In order to promote the bearing capacity of road, these materials, individually, or with the attendance of other materials add to sub base layers. During the recent years, road builders have … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Pile- Soil Interaction Subjected to Lateral Loads in Layered SoilsA. Avaei, Abdoul R. Ghotbi, M. AryafarTo stabilize infrastructures such as tall buildings, bridges, etc., piles are used to resist lateral loads created from earth pressure, wind, waves and earthquake extensively. Pile design requires understanding of how the load is transferred from a pile to surrounding soil and vice versa. Pile properties, soil stress-strain behavior and pile-soil interaction play important roles in pile-response subjected to lateral … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,342 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 · 6,915 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Optimization of a Porous Ti6Al4V Bone Construct Using Additive ManufacturingJeffrey Wilk, Glenn Sanders, Shelby Marks et al.Patient specific implants are becoming viable treatment options in some orthopaedic applications through advances in additive manufacturing and 3D printing techniques. One potential application is for treatment of segmental bone defects, particularly in patients suffering from bone cancer. Current treatment options are: Amputation, megaprosthesis, or allografts. These treatments are often highly invasive, may require a partial/full joint replacement and are … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 2 Jan 2017 · 7,818 accessesView PDFCite
