Research ArticleOpen accessIn the abstractElectromagnetic Interference Mitigation for Inverter fed AC DrivesC. Karthikeyan, K. DuraiswamyProblem statement: In switched mode PWM inverter EMI noise occurs during high (dv/dt) transient period. This EMI noise is mitigated using Active Common mode EMI filter in front of the source. Approach: This study proposes a new active common mode Electromagnetic Interference (EMI) filter for switched mode PWM Inverter applications. The proposed filter is based on current sensing and compensation … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 12 Sep 2011 · 7,309 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtension and Prerequisite: An Algorithm to Enable Relations Between Responses in Chatbot TechnologyAbbas Saliimi Lokman, Jasni Mohamad ZainProblem statement: Artificial intelligence chatbot is a technology that makes interactions between man and machines using natural language possible. From literature, we found out that in general, chatbot are functions like a typical search engine. Although chatbot just produced only one output instead of multiple outputs/results, the basic process flow is the same where each time an input is entered, … …Journal of Computer Science, Vol. 6, Issue 10 · 24 Aug 2010 · 16,993 accessesView PDFCite
Research ArticleOpen accessIn the abstractIterative Channel Estimation Algorithm in Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing SystemsMona Nasseri, Hamidreza BakhshiProblem statement: The objective of this study is improving channel estimation accuracy in MIMO-OFDM system because channel state information is required for signal detection at receiver and its accuracy affects the overall performance of system and it is essential to improve the channel estimation for more reliable communications. MIMO-OFDM system was chosen in this study because it has been widely … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 8,297 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Carbon Steel Pipe Protection Based on Radial Basis Function Neural NetworkSami Abulnoun AjeelProblem statement: The cost due to corrosion Damage have estimated to be 3-4% of their gross national product which significantly Countries problem around the world. Approach: In this study, a novel carbon steel pipe protection based on RBFNN was proposed. The RBFNN used to predict the minimum current density required in impressed current cathodic protection to protect low carbon steel … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 7,140 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling the Effect of P-N Junction Depth on the Output of Planer and Rectangular Textured Solar CellsF. Jahanshah, K. Sopian, S. H. Zaidi et al.Problem statement: High cost of the solar cells is one of the important limitations in extensively using of the photovoltaic panels. Thin monocrystalline silicon solar cell could be reduce the cost but lost the absorption efficiency. Surface texturing help to enhance absorption. Using of advance texturing by diffraction grating was suggested for high absorption. It is necessary to investigate the … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 8,219 accessesView PDFCite
Research ArticleOpen accessIn the abstractControl Strategy for Discontinuous Conduction Mode Boost Rectifier with Low Total Harmonic Distortion and Improved Dynamic ResponseH.S. AthabDue to its simplicity, the discontinuous conduction mode boost rectifier is potentially the least expensive active line-harmonics reducing circuit. Problem statement: The line current however, shows considerable distortion when the peak input voltage is close to the output voltage, As a result, the input power factor is poor. This study proposes a simple, low-cost method to reduce the line harmonics. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,418 accessesView PDFCite
Research ArticleOpen accessIn the abstractSource Couple Logic (SCL): Theory and Physical DesignMohamed Azaga, Masuri OthmanThis study describes and presents the analysis for the Source-Coupled Logic (SCL) inverter as will as the effect of submicron layout parasitics. The SCL inverter circuit model and its operation is defined. The analysis for the SCL is carried from the point of view of input/output voltage characteristics and the effect of noise margin. The inverter gate delay model is … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,466 accessesView PDFCite
Research ArticleOpen accessIn the abstractFast Power Loss Computation and Shunt Capacitor Insertion Using Fuzzy Logic TechniqueWagah F. Mohammad, Nabil Tawalbeh, Kasim M. Al-AubidyFast power loss computation was implemented using supervisory control and data acquisition system (SCADA) with personal computer. Logic Control Array (LCA) and EPROM circuits were used to implement SCADA system to facilitate the required measurements to obtain the daily load profile for residential and commercial customers. LCA, EPROM and PC were used to simplify the electronic circuits, reduce the cost … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 7,391 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrocontroller Based Power SupplyTanvir Singh Mundra, Er. Satwinder Singh Sachdeva, K.S. KahlonThese days, majority of electronic devices work on DC power source, so there was a requirement of a reliable and customized power supply. Generally, the requirements are not too varied, but still they require every time a new hardware designing. The idea presented here is to build a microcontroller controlled power supply[1] that is flexible enough to meet different customer … …Journal of Computer Science, Vol. 2, Issue 8 · 31 Aug 2006 · 6,781 accessesView PDFCite
