P121R25 is a Tn5-induced mutant of the effective Rhizobium leguminosarum bv. phaseoli strain P121R that is unable to use glutamate as the sole carbon and nitrogen source and is defective in symbiotic nitrogen fixation. Enzymatic analysis showed that three enzymes implicated in glutamate metabolism (glutamate dehydrogenase, 2-oxoglutarate dehydrogenase, and(More)
In this paper; we show how grid computing can further speedup Dynamic Time Warping (DTW) algorithm. More specifically, we present experimental results of the data distribution of the Arabic printed cursive OCR based on the Dynamic Time Warping (DTW) algorithm over the Scientific Research Tunisian Grid (SRTG). In fact, the Arabic printed cursive OCR based on(More)
This work consists on achieve an automatic correction system for Arabic continuous speech. This system will be combined by an ASR system for disabled people. For this work, we built a lexicon of 4.000.000 Arabic words through which decides if a word is correct or not. A corpus of Arabic texts is also required to provide a standard summarizing the appearance(More)
With data intensive applications it can be interesting to resort to a distributed storage to reach scalability and avoid data-intensive problems. Storing data permanently on computing nodes can be an interesting approach especially with the frequent use and the large volume of this data. Moreover, processing large data is a computing intensive task which(More)
Volunteer computing or volunteer grid computing constitute a very promising infrastructure which provides enough computing and storage powers without any prior cost or investment. Indeed, such infrastructures are the result of the federation of several, geographically dispersed, computers or/and LAN computers over the Internet. Berkeley Open Infrastructure(More)
