Automated Motion LoD with Rigid Constraints

Daniel Thalmann, Junghyun Ahn

Motion LoD (Level of Detail) is a preprocessing technique that generates multiple details of captured motion by eliminating joints. This LoD technique is applied to movie, game or VR environments for the purpose of improving speed of crowd animation. So fa ...

X-ray structure of a pentameric ligand-gated ion channel in an apparently open conformation

Pentameric ligand-gated ion channels from the Cys-loop family mediate fast chemo-electrical transduction, but the mechanisms of ion permeation and gating of these membrane proteins remain elusive. Here we present the X-ray structure at 2.9 A resolution of ...

Ultrasonic monolithic piezoelectric multi DOF actuators for mobile microrobots

Jean-Marc Breguet, Walter Driesen, Tomas Cimprich

We propose a new type of “hybrid” ultrasonic driving principle for our monolithic piezoelectric actuators, which consist of simple electrode patterning on a PZT ceramic substrate The operating principle of the proposed USM is based on the conversion of ell ...

Vehicle for rugged terrain

Roland Siegwart, Michel Lauria

The invention concerns a vehicle whereof the rigid body (1, 2, 4) comprises the front element (20) forming the rear element of a deformable articulated quadrilateral (17, 18, 19, 20). The element (17) is mounted in the extension of the arm (15) linked to t ...

Kinematic control of the mass properties of redundant articulated bodies

Ronan Boulic

In this paper we show how the mass properties of an articulated body, such as its center of mass and its moments of inertia, may be manipulated like any conventional end effector, with well-known iterative, numerical techniques. Within our interactive simu ...

Anatomic modeling of deformable human bodies

Daniel Thalmann

We propose a method to simulate human bodies based on anatomy concepts. We believe that the closer our model is to reality, the better our results will be. Using this approach, we are developing our human representation. Our model is divided into three lay ...

Anisotropy in the ab-plane optical properties of Bi2Sr2CaCu2O8 single-domain crystals

Giorgio Margaritondo, Helmuth Berger

The ab-plane optical properties of the high-temperature superconductor Bi2Sr2CaCu2O8 are anisotropic in both the normal and the superconducting state. Consistent with the orthorhombic structure, the principal axes lie along the a and b crystallographic axe ...

Three-Dimensional Motion Estimation of Objects for Video Coding

Luciano Sbaiz

Three-dimensional (3-D) motion estimation is applied to the problem of motion compensation for video coding. We suppose that the video sequence consists of the perspective projections of a collection of rigid bodies which undergo a rototranslational motion ...

A Pyramid Approach to Subpixel Registration Based on Intensity

Michaël Unser, Philippe Thévenaz

We present an automatic sub-pixel registration algorithm that minimizes the mean square difference of intensities between a reference and a test data set, which can be either tri-dimensional (3-D) volumes or bi-dimensional (2-D) images. It uses spline proc ...

Vertical instability in TCV: Comparison of experimental and theoretical growth rates

Jean-Marc Moret, Ivo Furno, Jonathan Bryan Lister

Growth rates of the axisymmetric mode in vertically elongated plasmas in the Tokamak a Configuration Variable (TCV) are measured and compared with numerically calculated growth rates for the reconstructed equilibria. This comparison is made over a range of ...
