Invited Speakers

• Thomas Jakobsen, Head of R&D, IO Interactive.
  
  
  
  
• John Perram, Professor from The Maersk Mc-Kinney Moller Institute for Production Technology, University of Southern Denmark.
  
  

  John will report on aspects of teaching analytical mechanics at the Maersk Institute in connection with the masters' program in computer systems engineering, including the use of Mathematica and interactive learning material to model, simulate and visualise low dimensional mechanical systems. The talk is illustrated with a case study in the form of a structured project in which students study the stability of an inverted pendulum hinged to a movable cart (commonly called broomstick balancing) using the techniques of constraint mechanics. Check out John's current course AM14(dynamical systems and chaos) page.

• Jeppe Johansen, Senior Research Scientist from Wind Energy Dept., Riso National Laboratory.
  
  

  Use of Computational Fluid Dynamics in Wind Turbine Design. Jeppe Johansen is working with Computational Fluid Dynamics (CFD) applied to wind mill rotors The primary goal is to develop a tool, which can make wind mills even more effective. This is done by solving the general (Navier-Stokes) equations it is possible to get a detailed description of the flow and thereby get a better understanding of the complex phenomena.

  
  
  
• Knud Henriksen, Assoiciate Professor from Copenhagen University of Computer Science.
  
  

  Scripted Bodies and Spline Driven Animation Knud Henriksen is going to give a talk about a new method developed at DIKU for computing a kinematic meaningfull trajectory based on a key frame animation. The method makes it possible to combine animated objects with physical based simulated objects. The method is also usefull for planning robot motion and computing inverse dynamics.

  
  
  
• Michael Damsgaard, Assoiciate Professor from Aalborg University, Institute of Mechanical Engineering, The Anybody Project.
  
  

  The AnyBody project is a biomechanical research project. The human body or the body of other creatures is modeled as a rigid body system and the inverse dynamic problem of finding the muscle activations for a given motion is solved. The AnyBody software has facilities for numerical optimization, which can be applied in the design of body-driven artifacts or for optimization of the motion/performance of the body. Please visit the homepage of the AnyBody research project at anybody.auc.dk or our recently started commercial branch, AnyBody Technology, at anybodytech.com

  Simulation of systems with changes of state Many simulation applications involve models of systems that may change state during the simulation. It is demonstrated how normal ODE-solvers will deteriorate in performance when a discontinuous change takes place in the right hand side of the dynamic model. By analysing the properties of the solution method the performance is improved and a general strategy for passing between states is developed under mild assumptions on the type of discontinuity. The use of continuous extensions is demonstrated to give an efficient passing procedure. Examples from implementation of the strategy is presented using examples from practical applications.
