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
Research ArticleOpen accessIn the abstractComparative Study on Sustainable Agriculture Knowledge among Malaysian Contract FarmersAzmariana Azman, Jeffrey Lawrence D’Silva, Bahaman Abu Samah et al.Problem statement: Modern farming methods like contract farming must emphasize on the need to practice sustainable agriculture so that it will lead towards the development of the agriculture sector. To do so, knowledge is paramount as this will enable the implementation of good agriculture practices. What is the current level of knowledge of contract farmers with regards to sustainable agriculture? … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 2 Mar 2012 · 8,082 accessesView PDFCite
Research ArticleOpen accessIn the abstractImage Compression Algorithms Using Intensity Based Adaptive Quantization CodingSaad Al-Azawi, Said Boussakta, Alex YakovlevProblem statement: Low complexity image compression algorithms are necessary for modern portable devices such as mobile phones, wireless sensor networks and high constraint power consumption devices. In such applications low bit rate along with an acceptable image quality are an essential requirements. Approach: This study proposes low and moderate complexity algorithms for colour image compression. Two algorithms will be presented; … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 18 Jan 2012 · 8,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Test for Two-Sample Repeated Measures Designs: Effect of High-Dimensional DataBoonyarit Choopradit, Samruam ChongcharoenProblem statement: High-dimensional repeated measures data are increasingly encountered in various areas of modern science since classical multivariate statistics, e.g,. Hotelling’s T2, are not well defined in the case of high-dimensional data. Approach: In this study, the test statistics with no specific form of covariance matrix for analyzing high-dimensional two-sample repeated measures designs with common equal covariance are proposed. The … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 28 Oct 2011 · 7,328 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Application of Local Wisdom for Production of Condiment Isan' Food Ingredient into CommercialNitchapanrawee PhengpholProblem statement: The problem of the research derives from a lack of study and understanding about the production of condiment Isan food and ingredients being introduced into commercial, even though Isan food is popular among consumers widespread both inside and outside the country. The government introduced a policy to expand trade to create an export value of Isan products. The … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 10 Oct 2011 · 7,217 accessesView PDFCite
