Research ArticleOpen accessIn the abstractGreenhouse Gas Mitigation Strategies for Container Shipping IndustryLin Shimin, Wong Yiik DiewWith the onset of the first ever Greenhouse Gas (GHG) regulation for ships by the International Maritime Organisation (IMO) in 2011, the container shipping industry requires the combined use of technical and operational emissions reduction measures to improve the environmental performance of its vessels. Studies show that most existing measures are cost effective with a range of emissions reduction potential. … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 4 · 14 Feb 2013 · 8,006 accessesView PDF Cite

Research ArticleOpen accessIn the abstractVoltage Stability of Short Transmission Line Equipped with a Thyristor Controlled Series CapacitorPrechanon KumkratugIt is becoming increasingly important to fully utilize the existing transmission system assets due to environmental legislation, rights-of-way issues, costs of construction and deregulation policies that introduced in recent years. The Thyristor Controlled Series Capacitor (TCSC) has been proposed for the better control power flow and dynamic performance. The exact short transmission line model consists of the resistance and reactance. … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 8 Nov 2012 · 6,698 accessesView PDF Cite
