Alexandru Patriciu McMaster University CANADA Topic: Parallel Algorithms for Needle Insertions in Soft Tissues using NVIDIA CUDA Abstract: Alexandru Patriciu is an Assistant Professor with the Department of Electrical and Computer Engineering, at McMaster University. His research interests lie in the areas of medical robotics, robotic assisted deformable objects manipulation, and parallel algorithms for surgical simulations. His keynote speech will address the issue of designing parallel algorithms for needle insertions in soft tissues using NVIDIA CUDA parallel architecture. Rafael Bidarra Delft University of Technology THE NETHERLANDS Topic: How'd You Like Your World Today? Abstract: Rafael Bidarra is an Associate Professor of Computer Science at Delft University of Technology, where he leads the Game Technology Research Lab at the Computer Graphics and Visualization Group. In this keynote, he will address the current game development challenge of coping with the huge amount of content in increasingly large game worlds. Much research has been seeking solutions for automating the content generation process. Procedural methods presently offer very promising results, but are still far from application in mainstream game development practice due to a number of shortcomings. He will discuss some of their drawbacks, and how they can be overcome, and introduce declarative modeling of virtual worlds, an approach aimed at enabling non technical professionals to build virtual worlds as they please. A variety of research results will be illustrated with recent examples. International CAD Conference and Exhibition, Final Program CAD 12 Volume 9 4 of 113

10th Annual CAD Conference June 17 20, 2013 Bergamo, Italy It is a pleasure to announce that the 10th anniversary International CAD Conference and Exhibition is planned to be held in Bergamo, Lombardy Region, Italy, June 17 20, 2013. Lombardy Region lies in the north of the country, sharing a border with Switzerland. Stretching from the Alps to the lowlands of the Po Valley, it is home to a wide range of landscapes, including the breath taking mountain chain, the charm of the great lakes, such as Garda Lake, Como Lake and Maggiore Lake. Beside Milan, the Region includes historical and industrial cities, such Bergamo, Brescia and others, where history, art and culture are harmoniously combined with innovation, technology, fashion, entertainment and a contemporary outlook. Contributions from all aspects of CAD are expected including Modeling, Analysis, High Performance Graphics, Data Management, Knowledge Engineering, Collaborative Design, Reverse Engineering, and Prototyping. Applications can be in Architecture, Bio Medicine, Civil Engineering, Fashion Industry, Industrial Design, Sustainable Energy Design, etc. Watch the website www.cadconferences.com for updates and further information.
