Research ArticleOpen accessIn the abstractSIMULTANEOUS OPTIMISATION OF DRYING PARAMETERS OF CERAMIC BODIESSalah Mahmoudi, Ezzeddine Srasra, Fouad ZargouniThis study deals with the mineralogical, physico-chemical and geotechnical analyses of representative Aptian clays in the north-east of Tunisia. X-ray diffraction reveals a predominance of illite (50-60 wt.%) associated to kaolinite and interstratified illite/smectite. The accessory minerals detected in raw materials are quartz, calcite and Na-feldspar. The average amounts of silica, alumina and alkalis are 52, 20 and 3.5 wt.%, … …Current Research in Geoscience, Vol. 4, Issue 1 · 1 Jul 2014 · 6,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementation of a Novel Control Strategy Using Fuzzy Logic Controller to Shunt Active Filter for Line Harmonic ReductionN. Senthilnathan, T. ManigandanProblem statement: Now days, power quality has been given attention due to the intensive use of power electronic equipments in all types of industries such as steel, paper, textile industries and so on. These power electronic devices induce harmonic distortion into the supply lines which gives rise to many undesirable effects. Approach: This study presents a new method for harmonic … …Journal of Computer Science, Vol. 8, Issue 5 · 29 Feb 2012 · 7,087 accessesView PDFCite
Research ArticleOpen accessIn the abstractCompositional Analysis on Ancient Bricks from Candi Sungai Mas (Site 32/34), Bujang Valley, KedahZuliskandar Ramli, Nik Hassan Shuhaimi Nik Abd. Rahman, Adnan Jusoh, Mohd. Zobir HusseinProblem statement: The significance of Kampung Sungai Mas as an importance archaeology site in Lembah Bujang was revealed in the year 1979 when a cannel was built along Kampung Sungai Mas area. During the construction study of this cannel, thousands of ceramic pieces from India, Middle East, China, Southeast Asia and Europe was discovered, pieces of glasses from Middle East … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 12 Dec 2011 · 9,839 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Abnormal Modes of Hoisting DC Electric Drive SystemKosmas ZdrozisProblem statement: Host number of publications in which special attention was given to the behavior of the hoisting drives in abnormal modes was found. The effect of the failure of the main power supply on the electrical and mechanical parts of the hoisting drive when the motor is operating in the regenerative braking mode was not enough studied. Approach: In … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,241 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Grain Size on Selected Physico-Chemical Properties of ClayOsumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Mixture of the right proportion of expanding and non-expanding clays to improve plasticity (moldability) of clays used in the pot industry of Malaysia is yet to be well investigated. In addition, little is known about the choice of the right clay size to eliminate or reduce the content of undesirable compounds such as Fe2O3, Al2O3 to improve the … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Model of 4-Quadrant DC Electric Drive with 6-Pulse Dual ConverterKosmas ZdrozisMathematical model simulating the operation of DC electric drive hoisting mechanism has been developed. The study illustrates the capabilities of the developed model for investigation both normal and abnormal modes of operation of the converter and the supplying voltage. Large attention was given to the thyristor converter and its firing system so that fast-proceed micro-processes occurring in the converter can … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,001 accessesView PDFCite
