Research ArticleOpen accessIn the abstractBehavior of Lightweight Coarse Aggregate RC Beams with Circular OpeningAdel A. Al-AzzawiThis pressent research investigates the mechanical properties of Waste Rubber Fibers Lightweight Coarse Aggregate Concrete (WRFLWAC) mixture. Also, the shear behaviors of 12 RC beams contain opening are investigated. The main study parameters are: The opening location, the waste rubber fiber ratio and the shear reinforcement. Deflection values and cracks are registered at each load step; also the cracking or … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 1 Apr 2017 · 7,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultiaxial Fatigue Strength to Notched specimens made of 40CrMoV13.9Abedin Gagani, Raffaella Aversa, Relly Victoria V. Petrescu et al.Fatigue is a process (succession of mechanisms) which under the action of time-varying strains or deformations modifies the local properties of a material. These can lead to the formation of cracks and eventual rupture of the structure. Fatigue is in particular characterized by an extent of variation in stress which may be well below the yield strength of the material. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 31 Dec 2016 · 8,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecent Results on the Brittle Fracture of Terfenol-D Specimens under Magnetic FieldMarco Colussi, Kotaro Mori, Fumio NaritaThe following investigation has the purpose of describing, both experimentally and numerically, the fracture behavior of a giant magnetostrictive alloy commercially known as Terfenol-D. Single-edge precracked specimens have been analyzed via three-point bending tests, measuring fracture loads in the presence and absence of a magnetic field at various loading rates. The Strain Energy Density (SED), averaged in a finite control … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 28 Dec 2016 · 7,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of RSA Exponential Key Growth on the Multi-Core Computational ResourceMohamad A. Mohamed, Ammar Y. Tuama, Mokhairi Makhtar et al.Cryptography has been widely used as a mean to secure message communication. A cryptosystem is made up of a publicly available algorithm and a secretly kept key. The algorithm is responsible for transforming the original message into something unintelligible. The result of losing the key or cracked algorithm can be catastrophic, where all secret communications will be known to adversaries. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 25 Nov 2016 · 7,827 accessesView PDFCite
Research ArticleOpen accessIn the abstractWelded Connections of Wind Turbine Towers under Fatigue Loading: Finite Element Analysis and Comparative StudyNafsika Stavridou, Evangelos Efthymiou, Charalampos C. BaniotopoulosIncreased contemporary energy needs have led to multiple investments on wind power plants and structural improvements are considered necessary for the construction of taller, more robust and more economical structures. Tubular steel wind turbine towers that are the prevailing structural configuration, demand welding of circular subparts to construct the tower structure. These circumferential welds between tower subparts and between the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 18 Aug 2015 · 8,894 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Effects of Application of Silica Fume to Reduce Asphalt Oxidative AgingNader Abutalib, Elham H. Fini, Sassan Aflaki, Taher M. Abu-LebdehThis paper investigates the feasibility of using silica fume to enhance the rheological properties of asphalt binder. It has been widely reported that asphalt binder oxidation is one of the phenomena that reduces the service life of asphalt pavement by negatively impacting its rheological properties. This in turn can lead to a more brittle pavement which is more prone to … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 8,485 accessesView PDFCite
Research ArticleOpen accessIn the abstractAN INNOVATIVE MORPHOLOGICAL APPROACH FOR NOISE REMOVAL CUM EDGE DETECTION FOR DIGITIZED PAINTINGSS. P. Karuppiah, S. K. SrivatsaThe older paintings suffer from breaks in the substrate, the paint, or the varnish. When we digitized these paintings, they can be modified using mathematical algorithms and cracks are eliminated so as to maintain the quality. The field of computer vision is concerned with extracting features and information from images in order to make analysis of images easier, so that … …Journal of Computer Science, Vol. 10, Issue 8 · 19 Jun 2014 · 6,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHORIA EHANCEMENT OF NUCLEAR REACTOR SAFETYBarbara Szpunar, Jerzy SzpunarThe recent nuclear accident in Fukushima demonstrates that a nuclear mishap should be viewed using interdisciplinary tools. For example, the urania fuel melts not only because of enhanced neutron flux but also because its thermal conductivity degrades when it oxidizes. Here we present the application of first principles calculations to evaluate the structural, mechanical and thermal properties of traditional urania … …Physics International, Vol. 4, Issue 2 · 20 Dec 2013 · 7,632 accessesView PDFCite
Research ArticleOpen accessIn the abstractStochastic Prognostic Paradigm for Petrochemical Pipelines Subject to FatigueAbdo Abou Jaoude, Khaled El-TawilThe most important aim for industrialists is the prevention and the evaluation of their products state since non-predicted failure is very expensive in some cases. This can be done mainly by the evaluation of the &#34Remaining Useful Lifetime&#34 (RUL) by the means of prognostic approaches compensating the inconveniences of classical maintenance strategies. A proposed analytic prognostic methodology based on damage … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 15 Apr 2013 · 7,557 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuails Response to Aqueous Extract of Bush Marigold (Aspilia africana) LeafE. A. Agiang, O. O.K. Oko, G. E. Essien, Juan Eduardo Suarez RivadeneiraProblem statement: The effects of inclusion of aqueous extract of Bush marigold (Aspilia africana) leaf in quail diet were investigated. One hundred and fifty Japanese quail chicks were used in the study. Approach: In the 14-weeks feeding experiment, the birds were assigned to five treatments of; 0, 2.5, 5.0, 7.5 and 10% inclusion of aqueous extract of Bush marigold leaf. … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 4 · 24 Jan 2012 · 9,582 accessesView PDFCite
