Research ArticleOpen accessIn the abstractComparative Study of Changing Drainage Basin System with Tectonic Forms, Case Study: Lut Block, IranEbrahim MoghimiThe study area locates in the east of Iran and it is morphologic block (unit). Problem statement: Sharp contrasts in the appearances of landscapes such as drainage basins with litology (kind of rock), tectonic regime, folding and climatic effect had been inspired geomorphologies in the past and now to devise schemes to explain those contrasts. These contrasts also remained and … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,274 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Neuro-Fuzzy Inference System-Particle Swarm Optimization Based Stability Maintenance of Power System NetworksR. Latha, J. KanakarajDuring faulty condition voltage instability is one of the major crisis in power system networks. This study proposes a hybrid learning algorithm to improve the stability performance of a power system with Distributed Generations (DGs). Here the distribution system stability is maintained with reduced power loss using an Adaptive Neuro-Fuzzy Inference Systems (ANFIS) and Particle Swarm Optimization (PSO) techniques. In … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 6,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Faulty Solar Panel Detecting and Mapping Method Using aDrone with RGB and Thermal Cameras in Solar Power PlantSoobin Jeon, Dongmahn SeoA solar panel generates electricity power using the sun's rays. It isusually located on a rooftop or open field without shadow. This solar panelis hard to be tested by nonprofessionals. Therefore, we propose a detectingsystem for a faulty solar panel using a drone with an RGB camera and athermal camera. The drone is applied for collecting aerial videos. The RGBcamera … …Journal of Computer Science, Vol. 21, Issue 5 · 21 May 2025 · 4,599 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetri Nets and Ladder Logic for Fully-Automating and Programmable Logic Control of Semi-Automatic Machines and SystemsMahmoud A. Barghash, Osama M. Abuzeid, Anas N. Al-Rabadi, Ahmad M. JaradatProblem statement: Automating semi-automatic dynamic machines and complex systems, where some functionalities are already automated but the machine doesn’t run fully in automatic mode, represents another challenge to automating dynamic and manual complex systems. This study deals with a special case of this general problem, where the system’s semi-automatic and automatic functionalities run separately in a sequence with either automatic … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,245 accessesView PDFCite
Research ArticleOpen accessIn the abstractNecessary Geomorphologic Information For Roads Safety, With Emphasize Soleghan Road In West Of Tehran, IranEbrahim MoghimiThis paper review some of the aspects of necessary disciplines of geomorphology and roads, with emphasize Soleghan road. For building this road didn’t consider geomorphology process carefully. so the safety rang of the road is low and with consider to increasing traffic, the rang of danger is high. Specific subjects are related to the description of slops phenomena, including rock … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,555 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatic Synchronous Series Compensator Controller based on Fuzzy Logic Control for Power System StabilizationPrechanon KumkratugProblem statement: Modern power system consists of the complicated network of transmission lines and carries heavy demand. Thus they cause in the stability problem. Approach: Static Synchronous Series Compensator (SSSC) is a power electronic based device that has the capability of controlling the power flow through a line. The series voltage injection model of SSSC is modeled into power flow … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 7 Sep 2011 · 7,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransient Stability Assessment of a Power System Using Probabilistic Neural NetworkNoor Izzri Abdul Wahab, Azah MohamedThis study presents transient stability assessment of electrical power system using Probabilistic Neural Network (PNN) and principle component analysis. Transient stability of a power system is first determined based on the generator relative rotor angles obtained from time domain simulation outputs. Simulations were carried out on the IEEE 9-bus test system considering three phase faults on the system. The data … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,029 accessesView PDFCite
Research ArticleOpen accessIn the abstractSTATCOM Stabilizer based on Fuzzy Logic Control for Damping Power OscillationPrechanon KumkratugProblem statement: In power systems, there exists a continuous challenge to improve dynamic performance of power system. Approach: Static Synchronous Compensator (STATCOM) is a power electronic based device that has the capability of controlling the power flow through a line. This study applies the Static Synchronous Compensator (STATCOM) to control the power flow during dynamic period. To verify the effect … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 8 Sep 2011 · 7,444 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review of Covering Arrays and Their Application to Software TestingBestoun S. Ahmed, Kamal Z. ZamliProblem statement: As a complex logic system, software may suffer from different source of faults. Those faults can be avoided by applying different testing processes. It appears recently that the interaction among the system factors represents a common source of faults. Software function properly, all input factors and their interactions of the software need to be tested i.e., exhaustive testing. … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 8,713 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 · 6,787 accessesView PDFCite
