Research ArticleOpen accessIn the abstractImprovement of Transient Stability of Power System Using Solid State Circuit BreakerKalai Murugan Amirthalingam, Raja Prabu RamachandranThe aim of this study is to use a solid state circuit breaker for the improvement of transient stability margin. Long distance AC transmission is often subject to stability problems, which limits the transmission capability. Interconnected power systems suffer from weakly damped swings between synchronous generator and sub systems. The development of modern power system has lead to an increasing … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 7 Jun 2013 · 7,005 accessesView PDFCite

AroraProblem statement: Bioinformatics in the present day microbiological research is an inevitable subject area that encompasses biological resources and high end computational skills to unravel the coded and encrypted information within the life. We have produced a brief account of the developments and tasks in the subject and upcoming challenges in the subject. The area has seen tremendous developmental pattern … …Current Research in Bioinformatics, Vol. 1, Issue 1 · 23 Jan 2012 · 14,793 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Decentralized Spectral Resource Allocation for Orthogonal Frequency Division Multiple Access Downlink of Femto Networks Via Adaptive Gradient Vector Step Size ApproachLamia Benmesbah, Bingo Wing-Kuen Ling, Vikram Chandrasekhar et al.Problem statement: For the Orthogonal Frequency Division Multiple Access (OFDMA) downlink of a femto network, the resource allocation scheme would aim to maximize the Area Spectral Efficiency (ASE) subject to constraints on the radio resources per transmission interval accessible by each femtocell. Approach: An optimal resource allocation scheme for completely decentralized femtocell deployments leads to a nonlinear optimization problem because … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 14 Jan 2012 · 7,637 accessesView PDFCite
Research ArticleOpen accessIn the abstractContemporary Sculptures: Decoding the Body of Aesthetic Knowledge Suitable for Public ParksAdool Booncham, Songkoon Chantachon, Sastra Lao-AkkaProblem statement: The contemporary sculptures are constructions in public parks for people to use and appreciate. These are new things which Thai society has just known. The knowledge and understanding of the matter as mentioned are still in the limited circle. However, there is a lack of research study to seek the body of aesthetic knowledge suitable for constructing sculptures … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 11 Oct 2011 · 6,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Debarking and Insecticidal Treatments Using Cypermethrin on Fresh Logs of Indonesian Pine, Pinus merkusii, on Attack by Ambrosia Beetle, Xyleborus sp.Paimin Sukartana, Mohammad Muslich, Ginuk SumarniProblem statement: Indonesian pine logs (Pinus merkusii Yungh. et de Vr.) are vulnerable to attack by ambrosia beetle Xyleborus sp. Fresh cut logs kept for months in logging area are subject to heavily attack by the beetles. Approach: An experiment was conducted to evaluate effectiveness of debarking and insecticidal treatments using cypermethrin on fresh logs of the wood species on … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 27 Sep 2011 · 7,916 accessesView PDFCite
Research ArticleOpen accessIn the abstractClassifying Single Trail Electroencephalogram Using Gaussian Smoothened Fast Hartley Transform for Brain Computer Interface during Motor ImageryV. B. Deepa, P. Thangaraj, S. ChitraProblem statement: Brain-Computer Interface (BCI) is a emerging research area which translates the brain signals for any motor related actions into computer understandable signals by capturing the signal, processing the signal and classifying the motor imagery. This area of work finds various applications in neuroprosthetics. Mental activity leads to changes of electrophysiological signals like the Electroencephalogram (EEG) or Electrocorticogram (ECoG). … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,658 accessesView PDFCite
Research ArticleOpen accessIn the abstractRadiometric Correction of Multitemporal Satellite ImagerySeema Gore Biday, Udhav BhosleProblem statement: Repeated observation of a given area over time yields potential for many forms of change detection analysis. These repeated observations are confounded in terms of radiometric consistency due to changes in sensor calibration over time, differences in illumination, observation angles and variation in atmospheric effects. Also major problem with satellite images is that regions below clouds are not … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 8,393 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust Decentralized Load Frequency Control Using Multi Variable QFT Method in Deregulated Power SystemsSeyed Abbas Taher, Reza HemattiThe Load Frequency Control problem has been a major subject in electrical power system design/operation and is becoming more significant recently with increasing size, changing structure and complexity in interconnected power systems. In practice LFC systems use simple proportional-integral controllers. However, since the PI control parameters are usually tuned based on classical or trial-and-error approaches, they are incapable of obtaining … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards a Theory and View of Teaching Compressed and Abbreviated Research Methodology and Statistics CoursesJames Carifio, Lisa EriksonOne of the highly questionable effects of educational reform and other curriculum reshaping factors at both the high school, post-secondary and graduate levels has been the shift to teaching compressed, pared-down or abbreviated courses in still needed or required subject-matter that became de-emphasized in the current educational reformation. Research methodology, particularly the highly quantitative and experimental kind and statistics, are … …Journal of Social Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,760 accessesView PDFCite
Research ArticleOpen accessIn the abstractMan Invades Nature: Tracing the Dynamics and Trends of Anthropogenic Stressors Within a Coastal Wetland EnvironmentEmmanuel Yeboah Okyere, Kofi Adu-Boahen, Bismark MensahCoastal areas contain some of the most valuable resources on earth that are constantly under threat due to human development. Notable among these resources are wetlands, a delicate but beneficial asset to coastal dwellers. This study studied the growth of Winneba City into the Muni Lagoon catchment as well as its associated effects on the Ramsar Site.
