This trend continues in the new millennium. Therefore, many challenges arise. To meet these challenges and to realize the resulting potentials, new approaches and solutions have to be developed. There- fore, research activities are becoming more and more important. This book represents an international platform for scientists to show their advances in research and development and the resulting applications of their work as well as and opportunity to contribute to international scientifi c discussion. The book Advances in Computer Science and Engineering constitutes the revised selec- tion of 23 chapters wri en by scientists and researchers from all over the world. The chapters are organized in four sections: Applied Computing Techniques, Innovations in Mechanical Engineering, Electrical Engineering and Applications and Advances in Applied Modeling. The fi rst section Applied Computing Techniques presents new fi ndings in technical approaches, programming and the transfer of computing techniques to other fi elds of research. The second and the third section; Innovations in Mechanical Engineering and Electrical Engineering and Applications; show the development, the application and the analysis of selected topics in the fi eld of mechanical and electrical engineer- ing. The fourth section, Advances in Applied Modeling, demonstrates the develop- ment and application of models in the areas of logistics, human-factor engineering and problem solutions. This book could be put together due to the dedication of many people. I would like to thank the authors of this book for presenting their work in a form of interesting, well wri en chapters, as well as the InTech publishing team and Prof. Lovrecic for their great organizational and technical work.
