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)
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)
Speech, as the most important means of communication between human beings, underwent several scientific studies, but until now there remains much to do with this phenomenon. After more than 60 years of research, the representation of speech has not exceeded the representation of the content (standard MPEG7). This paper presents a step towards a standard(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(More)
—Distributed computing is the method of splitting a large problem into smaller pieces and allocating the workload among many computers. These individual computers process their portions of the problem, and the results are combined together to form a solution for the original problem. At present, Distributed computing systems can be broadly classified into(More)
