Research ArticleOpen accessIn the abstractEmbedded Computer Based Active Vibration Control System for Vibration Reduction of Flexible StructuresVenkata Ratnam Tatavolu, Seetha Ramaiah PanchumarthyResearch on Active Vibration Control System (AVCS) is being carried out to reduce structural vibrations caused by unwanted vibrations in many application areas such as in space, aircraft structures, satellites, automobiles and civil structures (bridges), particularly at low frequencies. The unwanted vibration may cause damage to the structure or degradation to the structure’s performance. The AVCS comprises physical plant, a … …Journal of Computer Science, Vol. 9, Issue 7 · 15 Jun 2013 · 6,550 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhycoremediation and the Potential of Sustainable Algal Biofuel Production using WastewaterAdel A. Fathi, Mohamed M. Azooz, Mohamed A. Al-FredanWastewater remediation by microalgae is an eco-friendly process with no secondary pollution as long as the biomass produced is reused and allows efficient nutrient recycling. This study was undertaken to evaluate the remediation of wastewater by the green alga Chlorella vulgaris and the potential of these alga (biomass) to produce sustainable biofuel. The results shows that the cultivation of green … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 27 Feb 2013 · 7,536 accessesView PDFCite
