Research ArticleOpen accessIn the abstractPreliminary Design of a Power Transmission Shaft under Fatigue Loading Using ASME CodeStephen K. ArmahPower transmission shafting is a vital element of all rotating machinery. A complete shaft design involves many iterative phases and fundamental to this is the determination of preliminary dimensions of the shaft. This paper presents a comprehensive fatigue analysis approach of determining the initial dimensions of a power transmission shaft under fatigue loading based on American Society of Mechanical Engineers … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 7 Feb 2018 · 15,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeorge (Gogu) ConstantinescuRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.George (Gogu) Constantinescu (October 4, 1891 - December 11, 1965) was a Romanian scientist and engineer, often considered to be one of the most important Romanian engineers. He was responsible for creating a new field of mechanics, called "sonicity," which describes the transmission of energy through vibrations in fluid or solid bodies. He applied the new theory to numerous inventions: … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 5 Dec 2017 · 8,571 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison of Three-Phase Shunt Active Power Filter AlgorithmsMoleykutty George, Kartik Prasad BasuThe usage of parallel converters is ever increasing. However, the voltage and current harmonics, zero-sequence and negative- sequence components of voltage and current and reactive power present in parallel converters give an alarming signal to power system and power electronic engineers. This research discusses performance of three-phase shunt active power filter (APF) system using three different control techniques namely synchronous … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Detection and Classification Algorithm for Power Quality Disturbances using WaveletsC. Sharmeela, M. R. Mohan, G. Uma, J. BaskaranThis study presents a novel method to detect and classify power quality disturbances using wavelets. The proposed algorithm uses different wavelets each for a particular class of disturbance. The method uses wavelet filter banks in an effective way and does multiple filtering to detect the disturbances. A qualitative comparison of results shows the advantages and drawbacks of each wavelet when … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 6,632 accessesView PDFCite
Research ArticleOpen accessIn the abstractWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,546 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHydroelectric Power Generation from Reservoirs in Savannah River BasinTravis Michael Yates, Abdul Aziz KhanHydropower is generated from three reservoirs in the United States Army Corps of Engineers's Savannah District. These reservoirs include J. Strom Thurmond, Richard B. Russell, and Hartwell. Currently, a contract in place specifies that a certain amount of energy must be provided to the region. Analysis of 25 years of operational data has shown that a 90% reliable yield is … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 28 Feb 2024 · 5,090 accessesView PDFCite
