Review ArticleOpen accessIn the abstractExploitation of Battery Energy Storage in Load Frequency Control -A Literature SurveyAhmed Zurfi, Jing ZhangDeregulation of the electricity market and the continued attempts by the international community to reduce the effects of global climate change have resulted in a rapid increase in the usage of different renewable forms of energy such as the wind and solar energy. The availability of such renewables is highly sporadic in nature. Consequently, their integration into the power system … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 17 Dec 2016 · 8,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractVerification of Anchoring in Foundations of Wind Turbine TowersNafsika Stavridou, Evangelos Efthymiou, Charalampos C. BaniotopoulosTubular steel towers are the most common supporting structure of wind converters. The towers’ foundation covers an important part of the initial cost and its configuration depends heavily on the type of subsoil. Onshore structures are founded on spread footing foundations or pile foundations with the first being the commonest. In these spread footing foundations, the tower is either embedded … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 23 Nov 2015 · 8,394 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Evaluation of the Raking Energy in Damping System of Steel Stud Partition WallsSalah Amer, Sameer Hamoush, Taher M. Abu-LebdehNonstructural partition walls are usually specified based on the best practice without any structural design calculations. However, given the likely severe earthquake damage to nonstructural components and the substantial cost of repair to such components, it is imperative that we develop an understanding of the seismic response of the nonstructural partition walls when subjected to earthquake loading conditions. The main … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Nov 2015 · 7,640 accessesView PDFCite
Research ArticleOpen accessIn the abstractCross-Section Optimization of Sandwich-Type Cylindrical Wind Turbine TowersStylianos M. Vernardos, Charis J. GantesAs wind energy is aggressively expanding within the alternative sources' part of modern world's energy pie, the need of addressing various obstacles that limit further wind utilization becomes all the more urgent. From a structural engineering point of view, surmounting the tower-base diameter limitation, dictated by the current transportation capabilities, is one of the industry's primary issues. The concept presented … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 7 Aug 2015 · 7,993 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of Closed Loop LCL-T Resonant DC-to-DC Converter Using Low Cost Embedded ControllerM. Annamalai, M. Vijaya KumarThe aim of this study is to simulate and implement open loop and closed loop controlled DC-DC converter for stand-alone wind energy system. Wind turbines, however, are not always very efficient in the wind speeds that are most common to a region. Typically, wind energy systems are designed to be highly efficient in high wind speed and have a cut-off … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 4 · 6 Feb 2013 · 7,589 accessesView PDFCite
Research ArticleOpen accessIn the abstractSalinity, Temperature and Turbidity Structure in the Suva Lagoon, FijiAwnesh Singh, Than AungThe city of Suva is home to nearly a quarter of the population of the Fiji thereby placing a lot of anthropogenic pressure on its lagoon. The Suva lagoon (comprising of Suva Harbour and Laucala Bay) has been subject to substantial sediment inputs generated by erosion and human activities. Freshwater input into the lagoon comes predominantly from the Rewa River, … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 8,992 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 · 7,339 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Performance of EPS Footing for Lightweight Farm Structure on Peat SoilMohammad Abdullah, Bujang B.K. Huat, Rezuwan Kamaruddin et al.The objective of this research project was to find a potential replacement for the conventional pile foundation principally for peat soil. It is fundamentally meant for lightweight and impermanent agricultural farm structures. Preceding the design and development of the foundation the physical characteristics of the in-situ peat such as; peat depth, soil consolidation, soil compressibility, water table, liquid limit, soil … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatus of Air Quality with Potential Linkage to the Metrological Conditions in Three Major Cities of PakistanNaima Hamid, Muhammad Junaid, Syeda Maria Ali et al.Environmental pollution being fatal for all living organisms is growing adversely due to excessive industrialization and urbanization. Vehicular emissions have aggravated the situation and pose detrimental effects on human health. In this study, the trend of ambient air quality was analyzed in the three metropolitan cities of Pakistan, including Karachi, Lahore and Islamabad for a period of three years (2008-2010). … …American Journal of Environmental Sciences, Vol. 15, Issue 2 · 11 Mar 2019 · 8,854 accessesView PDFCite
Review ArticleOpen accessIn the abstractEducational Challenges in Computer-based Finite Element Analysis and Design of StructuresVagelis Plevris, Gro MarkesetComputer simulations and computational methods, such as the Finite Element Analysis (FEA) have become essential methodologies in science and engineering during the last decades, in a wide variety of academic fields. Six decades after the invention of the digital computer, advanced FE simulations are used to enhance and leapfrog theoretical and experimental progress, at different levels of complexity. Particularly in … …Journal of Computer Science, Vol. 14, Issue 10 · 26 Oct 2018 · 8,625 accessesView PDFCite
