Research ArticleOpen accessIn the abstractOptimization of Electric Power Distribution Using Hybrid Simulated Annealing ApproachWalid Ahmed, Alaa F. ShetaThe key goal of electric power distribution companies is to provide a high quality of service with a low cost of operation. The growing customer needs requires a re-distribution of the Power over various nodes of the Distributed Generation (DG) facilitates. The re-distribution might cause over load on various parts of the networks which if not correctly optimized might increase … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,606 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstablishment and Evaluation of the Vegetative Community in A Surface Flow Constructed Wetland Treating Industrial Park ContaminantsC.C. Galbrand, A.M. Snow, A.E. Ghaly, R. CôtéA surface flow constructed wetland, designed to curve in a kidney shape in order to increase the length to width ratio to 5:1 was used to treat runoff from an industrial park. A natural wetland system located approximately 200 m downstream of the constructed wetland was selected to act as the vegetative community model for the constructed wetland. The selected … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractStress and Job Satisfaction among Air Force Military PilotsKhodabakhsh Ahmadi, Kolivand AlirezaStress induces impairment of performance is a relatively common issue in pilots of military aviation. The present study aimed at gathering preliminary data on the relationship between stress and job satisfaction among military pilots, so determine to what extent military pilots suffering from job satisfaction. This study was cross- sectional in design and used survey methodology. The survey was offered … …Journal of Social Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 10,957 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolicy-Based Security for Wireless Components in High Assurance Computer SystemsLuay A. Wahsheh, Jim Alves-FossTo enable the growth of wireless networks in high assurance computer systems, it is essential to establish a security engineering methodology that provides system security managers with a procedural engineering process to develop computer security policies. Our research demonstrates how wireless communication technology is deployed using the Multiple Independent Levels of Security (MILS) architecture for high assurance computer system design … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 7,329 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroducing Radio-Opaque Radio-Lucent Graduated Root Canal Length Indicating Cones (GRCLIC) in EndodonticsMohammad Rashid Shahidi BonjarRadio Opaque-Radiolucent Graduated Root-Canal Length Indicating Cone (GRCLIC) is a new innovative device being introduced for the first time in endodontics literature. GRCLIC can present more accurate measurement of the root canal length in conventional radiographs in endodontic and root canal treatment. Like many other dental and medical specialties, endodontics has evolved and changed over the years. The changes that … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,095 accessesView PDFCite
Research ArticleOpen accessIn the abstractANN Based DSPIC Controller for Reactive Power CompensationR.A. Jayabarathi, N.B. DevarajanIn India with a power shortage of about 10% of installed capacity, the transmission and distribution losses are relatively high. One of the reasons for the large loss is the excessive reactive loads on the primary distribution feeder. With the right amount of reactive power compensation, as system load varies, line losses can be considerably reduced. The application of Artificial … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractAgent-Based Design for E-learning EnvironmentKhadidja Harbouche, Mahieddine DjoudiWe presented an agent-based e-learning environment. Our aim was to allow many users to interact collectively and intelligently with the environment. In this cooperation model, human users and artificial agents carry out tasks in the learners’ service. We define the internal structure of our kernel supposed to work within Internet/Intranet settings. Design was structured in three parts: individual learning space, … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,951 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputer Aided Transient Stability AnalysisNihad M. Al-Rawi, Afaneen Anwar, Ahmed M. Abdul-MajeedA program for handling and improving the transient stability of the Iraqi Super Grid electrical network was developed. The idea was demonstrated by applying it to the outages of the main generating units. The methodology was built upon a state of increasing power transfer through the healthy portion of network during disturbances. There were three parts concerned; the first part … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 6,943 accessesView PDFCite
Research ArticleOpen accessIn the abstractData Mining: A Preprocessing EngineLuai A. Shalabi, Zyad Shaaban, Basel KasasbehThis study is emphasized on different types of normalization. Each of which was tested against the ID3 methodology using the HSV data set. Number of leaf nodes, accuracy and tree growing time are three factors that were taken into account. Comparisons between different learning methods were accomplished as they were applied to each normalization method. A new matrix was designed … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 34,390 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Single-Phase Rectifier with Improved Power Factor and Low THD using Boost Converter TechniqueIsmail Daut, Rosnazri Ali, Soib TaibThe method of using Boost type of converter was proposed for a 300W single-phase rectifier in this paper. By designing the necessary techniques and methodology, the overall Power Factor (PF) and Total Harmonic Distortion would be improved to the expectation. The cause of having low PF and high THD for a diode-capacitor type of rectifiers is related to non-linearity of … …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 7,127 accessesView PDFCite
