A MPEG-4 virtual human animation engine for interactive web based applications

This paper presents a novel, MPEG-4 compliant animation engine (body player). It has been designed to synthesize virtual human full-body animations in interactive multimedia applications for the web. We believe that a full-body player can provide a more ex ...

Capacities in metric spaces

Marc Troyanov

We discuss the potential theory related to variational capacity and the Sobolev capacity on metric measure spaces. We prove our results within the axiomatic framework. ...

Estimating equilibrium properties from non-Hamiltonian dynamics

Ursula Röthlisberger

We derived an expression that enables the accurate estn. of equil. properties using non-Hamiltonian dynamics. The major advantage of our scheme is that a time av. over a single non-Hamiltonian trajectory can be employed instead of an ensemble av. Hence, it ...

A Unifying Approach and Interface for Spline-Based Snakes

Michaël Unser, Thierry Blu, Mathews Jacob

In this paper, we present different solutions for improving spline-based snakes. First, we demonstrate their minimum curvature interpolation property, and use it as an argument to get rid of the explicit smoothness constraint. We also propose a new externa ...

Optimal control of nonmodal disturbances in boundary layers

Peter Corbett

"The optimal control of infinitesimal flow disturbances experiencing the largest transient gain over a fixed time span, commonly termed ""optimal perturbations,"" is undertaken using a variational technique in two- and three-dimensional boundary layer flow ...

Electrochemical oxidation of benzoic acid on boron doped diamond electrodes

Christos Comninellis, Pierre-Alain Michaud

The oxidn. of benzoic acid has been performed on boron doped diamond electrodes supported on silicon substrate. The voltammetric behavior has shown that during the oxidn. of benzoic acid at 2.7V (RHE), a polymeric film is formed on the electrode surface th ...

A wireless electrochemiluminescence detector applied to direct and indirect detection for electrophoresis on a microfabricated glass device

A novel electrochemiluminescence (ECL) detector is presented in this article. The detector is applied for micellar electrokinetic chromatographic separation of dichlorotris(2,2′-bipyridyl)ruthenium(II) hydrate [Ru(bpy)] and dichlorotris(1,10-phenanthroline ...

Statics and dynamics of the magnetic soliton lattice in the high-field phase of CuGeO3

Henrik Moodysson Rønnow, Mechthild Enderle

Driven by antiferromagnetic quantum fluctuations on a deformable lattice, spin-Peierls systems dimerize magnetically and structurally at low temperatures. In this dimer phase all excitations with non-zero magnetization have a finite energy. The energy gain ...

Stimulated polariton scattering in semiconductor microcavities: New physics and potential applications

Raphaël Butté

Stimulated polariton scattering in semiconductor microcavities is reported. The phenomena arise from the bosonic character of the coupled exciton-photon modes of the system. The ability to manipulate and control the polariton dispersions in microcavities i ...

Aspects of aqueous ruthenium(II) chemistry

André Merbach, Gabor Laurenczy, Pascal Grundler

Since the first facile synthesis of Ru(H2O)(6)(2) was published at the beginning of the eighties, several Ru-II aqueous inorganic and organometallic complexes were described, showing the increasing interest in this kind of compound due to potential ...
