In this paper, methods and algorithms are presented for an efficient slicing process specifically designed for microstereolithography, a high-resolution rapid prototyping technology. Modifications are given for different implementation environments (FPU, Parallel Computing, directly wired processes). They use the common STIL-format as the description of the 3D objects and compute bitmapped layers for the layered manufacturing step. Specific attention was paid to the requirements for flexibility, accuracy, s

Chem. mechanisms are used in 3D air quality models as well as for modeling lab. expts. Depending on the application the required detailedness of the mechanism differs. The mechanism generation program CHEMATA (Chem. Mechanism Adaptation to Tropospheric Applications) is able to generate explicit or lumped mechanisms according to the wishes of the user. In this work CHEMATA is applied for investigating the influence of different designs of mechanisms on the simulation results in a boxmodel study.

Presents a new architecture for simulating virtual humans in complex urban environments. The approach is based on the integration of six modules. Four key modules are used in order to manage environmental data, simulate human crowds, control interactions between virtual humans and objects, and generate tasks based on a rule-based behavioral model. The communication between these modules is made through a client/server system. Finally, all low-level virtual human actions are delegated to a single motion and

We present an image-based rendering technique to represent virtual humans in real-time. Though we deal only with virtual humans, the concept can be applied to any articulated character. Our technique is termed animated impostors because it extends the notion of dynamic impostors to take into account changes in the character's appearance. We also show how impostors can be embedded into large-scale simulations/applications

The paper deals with the main problems to solve in order to simulate precisely the behavior of complex power systems with mixed elements (power components and digital regulation devices). A simulation tool developed at the Swiss Federal Institute of Technology is shortly described. Finally, an industrial application of an induction motor fed by a three-level inverter tuned with a DTC (Direct Torque Control) is presented.

Interaction between real and virtual humans covers a wide range of topics from creation and animation of virtual actors to computer vision techniques for data acquisition from real world. We discuss the design and implementation of an augmented reality system which allows investigation of different real/virtual interaction aspects. As an example we present an application to create real time interactive drama with real and virtual actors

Analysis of the deflection of a circular membrane under differential pressure (bulge test) is a well-known method of determining the elastic properties of thin films. However, analytical models always suffer from simplifying hypotheses. In this study we present a new approach, based on numerical modeling, to interpret pressure-deflection curves. By adjusting Young’s modulus and Poisson’s ratio in the simulation program, it is possible to reproduce the experimental curves faithfully. The method was successfu

The present paper describes a stator flux oriented control strategy using state space controllers. The optimal determination of different controllers'parameters (suitable placement of poles, continuous adapation of coefficients to the operating point of the drive) leads to an independent control of the stator flux and the torque in different operating conditions, and consequently to good dynamic performances of the drive. The effectiveness of the proposed system is verified by computer simulation. The contr

Collision detection tests between objects dominate run time simulation of rigid body animation. Traditionally hierarchical bounding box tests are used to minimize collision detection time. But the bounding boxes do not take shapes of the objects into account which results in a large number of collision detection tests. We propose an adaptive spatial subdivision of the object space based on octree structure to rectify this problem. We also present a technique for efficiently updating this structure periodica

We have examined the role of the nonlinear elastic properties of the arterial wall on the human aortic input impedance obtained at different heart rates and different pressure and flow wave shapes. Pressure and flow were taken from a computer model that provides realistic simulations of the nonlinear distributed systemic arterial tree. Different wave shapes of ascending aorta pressure and flow and different heart rates were used to derive input impedance moduli and phase angles via Fourier analysis. The res

Summary form only given. This paper discusses the problem of control and autonomy of synthetic actors. It first describes an animation approach where synthetic vision is used for navigation by a synthetic actor. The vision is the only channel of information between the actor and its environment and offers a universal approach to pass the necessary information from the environment to an actor in the problems of path searching, obstacle avoidance, and internal knowledge representation with learning and forget
