Research ArticleOpen accessIn the keywordsPerformance 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 PDF Cite

Research ArticleOpen accessIn the abstractDirect Sequence and Frequency Hopping Signals Classification Based on Co-Occurrence Matrix and Clustering TechniquesHaidy S. Fouad, Hend A. Elsayed, Shawkat K. GirgisSpread Spectrum techniques (SS) were first developed for military applications, but currently, they have commercial applications. SS provides secure communication and allows multiple accesses for same radio spectrum. So, most Wireless Local Area Network (WLAN) systems use it, as do Cognitive Radios (CR), space systems and Global Positioning Systems (GPS). Direct Sequence Spread Spectrum (DSSS) and frequency hopped spread spectrum … …Journal of Computer Science, Vol. 15, Issue 1 · 10 Jan 2019 · 8,203 accessesView PDF Cite

InvestigationOpen accessIn the abstractAn Investigation into Labouchère’s Betting System to Improve Odds of Favorable Outcomes to Generate a Positive Externality EmpiricallyJake Billings, Sebastian Del BarcoThe Labouchère gambling system is hypothesized to increase the probability of winning a predetermined arbitrary profit in a gambling system such as a coin flip or a roulette game in which both payouts and odds are 1:1. However, use of the system increases the downside monetary risk in the event of a streak of multiple losses. To begin, a player … …Journal of Mathematics and Statistics, Vol. 13, Issue 3 · 26 Aug 2017 · 7,833 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUnique Representation of Positive Integers as a Sum of Distinct Tribonacci NumbersSalim Badidja, Abdelmadjid BoudaoudLet (Tm)m≥1 be the tribonacci sequence. We show that every integer N ≥ 1 can be written as a sum of the terms αm Tm, where m runs over the set of strictly positive integers and αm (m ≥ 1) are either 1 or 0. The previous representation of N is unique if each time that we have αm = … …Journal of Mathematics and Statistics, Vol. 13, Issue 1 · 16 Mar 2017 · 8,596 accessesView PDF Cite

Research ArticleOpen accessIn the abstractZero Geometry, Zero Space Time, The Seeds of The Final TheoryKambiz-AfrasiabiProblem statement: Lack of understanding And scientific formulation of zero geometry and zero space-time and the truth about initiation conditions would continue to keep us all in dark and we would continue to create more theories defining our observations about the known universe which could Indeed be part of our illusionary perception of reality And as long as they continue … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 10 Oct 2011 · 7,846 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Porcine Mitochondrial Transcription Factor a Gene: Molecular Characterization, Radiation Hybrid Mapping and Genetic Diversity among 12 Pig BreedsTanja Kunej, Xiao-Lin Wu, Jennifer J. Michal et al.Problem statement: Mitochondrial transcription factor A (TFAM) is a nucleus-encoded protein that is a key activator of mitochondrial transcription as well as a major participant in mitochondrial genome replication. Genomic characterization of the porcine TFAM gene is, therefore, necessary to determine its involvement in regulation of fat depots and meat quality traits in pigs. Approach: Genomic DNA sequence was determined … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 6,870 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProtection for an Immediate Split Structure of Tree-Based EPON Architecture-Ideal Condition AnalysisMohammad Syuhaimi Ab-Rahman, Siti Asma Che Aziz, Kasmiran JumariProblem statement: Ethernet Passive Optical Network (EPON) was proposed to overcome the bandwidth bottleneck at the Access Networks due to its simplicity, cost effective and wide spread deployment. A failure in access networks can cause serious problems, because access network transmit aggregated high speed traffic from hundreds of subscribers. Protection and restoration mechanisms have been applied in backbone networks, but … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,276 accessesView PDF Cite
