Research ArticleOpen accessIn the abstractBase Course Modification through Stabilization using Cement and BitumenS. M. Marandi, P. SafapourThe main objectives of this research was to analyze the use of combined cement and bitumen emulsion in base course stabilization in details and examine its replacement with conventional pavement in regions with low quality materials and limited construction period. To conduct the objectives, the research divided into three phases. Phase I involved the optimization of cement and bitumen emulsion. … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractFracture and springback on Double Bulge Tube Hydro-FormingF. Djavanroodi, M. GheisaryThis research aims to establish a basic understanding of Double Bulge Tube Hydro-Form processing of stainless steel deep drawn cups. The method is briefly reviewed by carrying out experimental tests and Finite element analysis. By measuring bulge height in both formed curves by Coordinate measuring machine (CMM) and thickness variation specimen by Ulterasonic thickness measurment device (UTM), it has been … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecentralized Controller Design for Static Synchronous Compensator Using Robust Quantitative Feedback Theory MethodSeyed Abbas Taher, Reza Hematti, Ali Abdolalipour, Majid NematiThe Static Synchronous Compensator (STATCOM) provides shunt compensation in similar way to the Static VAR Compensator (SVC) but utilizes a voltage source converter rather than capacitors and reactor. In practice systems use simple Proportional-Integral (PI) controllers for control of STATCOM. However, since the PI control parameters were usually tuned based on classical or trial-and-error approaches, they were incapable of obtaining … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Different Control Strategies in GA-Based Optimized UPFC Controller in Electric Power SystemsSeyed Abbas Taher, Reza Hematti, Majid NematiThis study presents a study of the application of a Unified Power Flow Controller (UPFC) to control power transmission, generator terminals voltage and better damping of Low Frequency Oscillation (LFO) in Single-Machine Infinite-Bus (SMIB) power system. The UPFC integrates properties of both shunt and series compensations and can effectively alter power system parameters in a way that increases power transfer … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,599 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransportation EngineeringRelly Victoria V. Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion T. PetrescuThe shipments were absolutely necessary at all times, but still have polluted and damaged the environment. The technique of transport or the engineering of transport is the application of the principles of technology and scientific findings to the planning, design check, operation and plan management for any mode of transport, in order to ensure that the conditions of safety, efficiency, … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 20 Jul 2017 · 8,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Nano Silica on the Compressive Strength of Harden Cement Paste at Different Stages of HydrationJustin Montgomery, Taher M. Abu-Lebdeh, Sameer A. Hamoush, Miguel PicornellThis study investigated the compressive strength of hardened cement paste and the formation of Calcium Silicate Hydrate (C-S-H) with the addition of nano silica (SiO2). Compressive strength testing was performed using MTS and Forney testing machines to determine stress-strain curves and compressive strength of the materials. The hydration process and formation of C-S-H and Calcium Hydroxide (CH) was examined using … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 8,333 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Evaluation of Tractors and Tillage Implements Instrumentation SystemS. A. Al-Suhaibani, A. A. Al-Janobi, Y. N. Al-MajhadiProblem statement: Field machines contribute a major portion of the total cost of crop production. Proper selection and matching of farm machinery is essential in order to reduce the cost of crop production. Performance data for tractors and implements are, therefore, essential for farm machinery operators and manufacturers alike. The aim of this study was to develop and evaluate an … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,304 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 · 14,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgressive Resistance Training on Elderly HIV+ Patients: Does it Work?Paula Maria Loiola De Souza, Wilson Jacob Filho, José Maria Santarém et al.Elderly people present significant alterations on body composition and physical fitness, compromising their quality of life. Chronic diseases, including HIV/AIDS, worsen this situation by increasing aging effects on body composition and muscle strength. Resistance exercises are prescribed by major health organizations for improving fitness and promoting a shift towards a healthier and more independent aging. In addition, recovering strength and … …American Journal of Infectious Diseases, Vol. 4, Issue 4 · 31 Dec 2008 · 6,740 accessesView PDFCite
