Research ArticleOpen accessPhrase in the titleHeat Transfer Enhancement of Small Scale Heat Sinks Using Vibrating Pin FinSuabsakul Gururatana, Xianchang LiHeat sinks are widely adopted in electronics cooling together with different technologies to enhance the cooling process. For the small electronics application, the small scale pin fins heat sinks are extensively used to dissipate heat in electronics devices. Due to the limit of space in the small devices, it is impossible to increase heat transfer area. In order to improve … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 6,867 accessesView PDFCite
Research ArticleOpen accessIn the abstractParticle Swarm and Neural Network Approach for Fault Clearing of Multilevel InvertersR. M.S. Parvathi, M. SivakumarThis study presents a machine learning technique for fault diagnostics in induction motor drives. A normal model and an extensive range of faulted models for the inverter-motor combination were developed and implemented using a generic commercial simulation tool to generate voltages and current signals at a broad range of operating points selected by a Particle Swarm Optimization (PSO) based machine … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 8 Jun 2013 · 6,486 accessesView PDFCite

Research ArticleOpen accessIn the abstractMicroelectrical Mechanical Systems Switch for Designing Multi-Band AntennaA.H.M. Zahirul Alam, Md. Rafiqul Islam, Sheroz Khan, Muhammad Mahbubur RashidProblem statement: In this study Microelectrical Mechanical System (MEMS) switches were proposed to design a reconfigurable/multi-band antenna to replaced PIN diode switches or semiconductor switches due to lower insertion losses, good isolation, much lower intermodulation distortion, and lower power consumption. The antenna is able to operate at very high frequencies. Approach: A reconfigurable antenna that is capable to operate at … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 6,687 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOn Prediction of Depreciation Time of Fossil Fuel in MalaysiaNora Muda, Tey Jin PinProblem statement: The fossil fuels play a crucial role in the world energy markets. Demand for fossil fuels become increasingly high and worrisome, because of fossil fuels will be significantly reduced and ultimately exhausted. This study was conducted to predict the depreciation time of fossil fuels in Malaysia and estimate the time remaining before the fossil fuels will finish. Approach: … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 10 Feb 2012 · 8,594 accessesView PDFCite
