A Publication of The Science and Information Organization A Publication of The Science and Information Organization (IJACSA) International Journal of Advanced Computer Science and Applications, Vol. 2, No. 5, 2011 IJACSA Editorial From the Desk of Managing Editor… It is a pleasure to present our readers with the May 2011 Issue of International Journal of Advanced Computer Science and Applications (IJACSA). With monthly feature peer-reviewed articles and technical contributions, the Journal's content is dynamic, innovative, thought- provoking and directly beneficial to the readers in their work. The number of submissions have increased dramatically over the last issues. Our ability to accommodate this growth is due in large part to the terrific work of our Editorial Board. Some of the papers have an introductory character, some of them access highly desired extensions for a particular method, and some of them even introduce completely new approaches to computer science research in a very efficient manner. This diversity was strongly desired and should contribute to evoke a picture of this field at large. As a consequence only 29% of the received articles have been finally accepted for publication. With respect to all the contributions, we are happy to have assembled researchers whose names are linked to the particular manuscript they are discussing. Therefore, this issue may not just be used by the reader to get an introduction to the methods but also to the people behind that have been pivotal in the promotion of the respective research. By having in mind such future issues, we hope to establish a regular outlet for contributions and new findings in the field of Computer science and applications. Therefore, IJACSA in general, could serve as a reliable resource for everybody loosely or tightly attached to this field of science. And if only a single young researcher is inspired by this issue to contribute in the future to solve some of the problems sketched here or contribute to exiting methodologies and research work, the effort of all the contributors will be rewarded. In that sense we would like to thank all the authors and reviewers that contributed to this issue for their efforts and their collaboration in this project. We hope to continue exploring the always diverse and often astonishing fields in Advanced Computer Science and Applications. Thank You for Sharing Wisdom!
