In this work we study the effect of some electrical prosperities on synthetic rubber reinforced with carbon black diluted in heptanes with concentrations from 0.2% gm/mole to 2.0% gm/ mole in temperatures range (100, 150, 200, 250, 300) C associated with amount weight of black carbon 5wt% added to the diluted rubber. The results of electrical properties measurement of Buna rubber reinforced wit...

In this paper, utilization of clustering algorithms for data fusion in decision level is proposed. The results of automatic isolated word recognition, which are derived from speech spectrograph and Linear Predictive Coding (LPC) analysis, are combined with each other by using fuzzy clustering algorithms, especially fuzzy k-means and fuzzy vector quantization. Experimental results show that the ...

Three strains of facultatively anaerobic thermotolerant and moderately halophilic bacteria were isolated from two Jordanian hot spring locations. The novel Bacillus strains were short rods, Gram-positive, motile and spore formers. The strains were capable of anaerobic (but not aerobic) growth at 63C, moderately halophilic, able to grow at NaCl concentration range of 12 15 % and at temperatures ...
