Research ArticleOpen accessIn the keywordsUse of Recycled Aggregate and Fly Ash in Concrete PavementMyle Nguyen James, Wonchang Choi, Taher Abu-LebdehProblem statement: Recycled materials aggregate from the demolished concrete structures and fly ash from burning coal shows the possible application as structural and non structural components in concrete structures. This research aims to evaluate the feasibility of using concrete containing recycled concrete aggregate and fly ash in concrete pavement. Approach: Two water cement ratio (0.45 and 0.55) the compressive strength, … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 12 Jul 2011 · 9,309 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUtilization of Bone Adhesive to Produce Particleboards from Stems of Cotton Plant at the Pressing Temperature of 140°CKomi Kadja, Magolmeena Banna, Kokou Esso Atcholi, Komla SandaProblem statement: To value agricultural residues, a study was carried out to investigate mechanical and physical properties of particleboards produced from stems of cotton (Gossypium hirsutum L.) by using bone adhesive. Approach: In order to obtain particleboards with minimum physical and mechanical properties as required in the conventional standards for general purpose particleboards, the optimum pressure temperature and the optimum … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,270 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFreezing and Thawing Durability of Very High Strength ConcreteSameer Hamoush, Miguel Picornell-Darder, Taher Abu-Lebdeh, Ahmed MohamedProblem statement: The newly developed Very High Strength Concrete (VHSC), having compressive strengths of 29 ksi and flexural strengths of 6 ksi, represents a breakthrough in concrete technology. Study to further enhance the properties of this new concrete is continuing. Approach: The objective of this study is to investigate the effect of exposing Very High Strength Concrete (VHSC) specimens to … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 28 Jan 2011 · 8,817 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluences of Short Discrete Fibers in High Strength Concrete with Very Coarse SandMahyuddin Ramli, Kwan Wai HoeProblem statement: High Strength Concrete (HSC) normally content high cementitous amount and low water binder ratio. However, these would cause substantial volume changes to the concrete and therefore affected the strength development. In addition, the brittleness of HSC was increased when silica fume used as partial cement replacement to achieve high strength. Approach: This study discussed the effects of incorporated … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,812 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLow Power Phase Locked Loop Frequency Synthesizer for 2.4 GHz Band ZigbeeNesreen Mahmoud Hammam Ismail, Masuri OthmanProblem statement: Wireless communication systems are required for many applications. There are different standards for these systems. IEEE 802.15.4 defines the communication system standard for zigbee. This study discussed designing one of the blocks of zigbee transceiver which is the Phase Locked Loop (PLL). A major target for any communication systems is saving battery power, especially for zigbee as it … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,057 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPrediction of Permanent Deformation of Pavement's Unbounded Layers Based on Cyclic Triaxial TestsB. ŽlenderThis research presents an analytical model for determining permanent deformation of pavement's sub-grade and unbound granular base and sub-base material due to cyclic traffic loading. The model is given for interpreting results of repeated load triaxial tests. It considers long term elastoplastic behavior and resilient behavior of sub-grade and unbound granular material. Permanent deformations are expressed as a function of … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,123 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIdentification, 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 accessIn the keywordsPrediction in Complex Dimension Using Kolmogorov's Set of AxiomsAbdo Abou Jaoude, Khaled El-Tawil, Seifedine KadryProblem statement: The five basic axioms of Kolmogorov define the probability in the real set of numbers and do not take into consideration the imaginary part which takes place in the complex set of numbers, a problem that we are facing in many engineering systems. Approach: Evaluate the complex probabilities by considering supplementary new imaginary dimensions to the event occurring … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 8,519 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIdentification of Shear Band using Elastic Shear Wave PropagationT. Nachiengtai, W. Chim-Oye, S. Teachavorasinskun, W. Sa-NgiamviboolLocalization in soil under high stress level is usually investigated using some indirect measures, e.g., X-ray diffraction method. In the present study, the propagation velocity of shear wave was used to detect localization in sandy soil. Firstly, the general expression to exhibit the stress and density dependencies characteristics under consolidation and triaxial testing conditions of the tested soil was proposed. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 6,794 accessesView PDFCite
