Over the last twenty years, the open source community has provided more and more software on which the world’s High Performance Computing (HPC) systems depend for performance and productivity. The community has invested millions of dollars and years of effort to build key components. But although

The Common Component Architecture (CCA) provides a means for software developers to manage the complexity of large-scale scientific simulations and to move toward a plug-and-play environment for high-performance computing. In the scientific computing context, component models also promote

in the domain of reaction kinetics, combustion and atmospheric chemistry from School of Chemistry. With his enthusiasm, he has provided very useful input to the case study of this work. Many thanks to other chemists from School of Chemistry for their help on the case study. Especially, thanks to Dr Kevin Hughes

We are glad and proud that we have been able to hold the International Conference on Contemporary Issues in Computer and Information Science for the third successive year, with your delightful presence; the conference which, besides special attention to the scientific progress in this subject, is aimed at bringing better interaction between different areas of computer science and everyday life, and acknowledges this fraternity a must for the progress of the society. By this approach, the CICIS Conference pays direct attention to several applicatory aspects of computer science and information. The third conference is held with concentration on Graph and Geometrical Algorithms, Intelligent Systems, Bioinformatics, IT and the society, in addition to all computer areas. What makes us more glorious is the coincidence of this conference with the 20th anniversary of the creation of Institute for Advanced Studies in Basic Sciences where outstanding scientific achievements is carried out in a friendly environment which would never have happened without God assistance and notable effort of the directors, teachers, researchers and students. Number of 277 received papers indicates kind feedback and makes us more determined.
