Reinforcement Learning for Imitating Constrained Reaching Movements

Aude Billard, Sylvain Calinon, Micha Hersch

The goal of developing algorithms for programming robots by demonstration is to create an easy way of programming robots that can be accomplished by everyone. When a demonstrator teaches a task to a robot, he/she shows some ways of fulfilling the task, but ...

ELM-wall interaction on JET and ITER

Richard Pitts

Significant interaction of ELM filaments with the vessel wall is now observed on JET by several diagnostics. To interpret the experimental data, a model of ELM-filament evolution was developed, with the radial velocity taken from experiment and the decay o ...

Tool Path Generation and Post-Processor Issues in Five-Axis High Speed Machining of Hydro Turbine Blades

François Avellan, Christophe Tournier

This paper deals with 5-axis milling of hydraulic blades. The issue developed is essentially linked to problems due to the transition from 3 to 5 axes. A specific attention is done to the Inverse Kinematics Transformation (IKT) which can be source of incoh ...

Lagrangian Stochastic Modeling of Heavy Particle Trajectories in Atmospheric Turbulence

Jan Overney

Particle transport in atmospheric boundary layer turbulence is simulated using Lagrangian Stochastic Models (LSM) coupled with a Large Eddy Simulation (LES) model of atmospheric boundary layer flow. The aim of this work is to improve the accuracy of transp ...

Automatic Tracking of Individual Fluorescence Particles: Application to the Study of Chromosome Dynamics

Michaël Unser, Daniel Sage

We present a new, robust, computational procedure for tracking fluorescent markers in time-lapse microscopy. The algorithm is optimized for finding the time-trajectory of single particles in very noisy dynamic (two- or three-dimensional) image sequences. I ...

Motion Level-of-Detail: A Simplification Method on Crowd Scene

Junghyun Ahn

Recent technological improvement in character animation has increased the number of characters that can appear in a virtual scene. Besides, skeletal and mesh structures are expected to be more complex in the future. Therefore, simulating massive characters ...

Human walking along a curved path. I. Body trajectory, segment orientation and the effect of vision

Grégoire Courtine

Task‐related characteristics of gait and segment orientation during natural locomotion along a curved path have been described in order to gain insight into the neural organization of walking. The locomotor task implied continuous deviation from straight‐a ...

On Factorizing Spectral Dynamics for Robust Speech Recognition

Hervé Bourlard, Hemant Misra, Vivek Tyagi

In this paper, we introduce new dynamic speech features based on the modulation spectrum. These features, termed Mel-cepstrum Modulation Spectrum (MCMS), map the time trajectories of the spectral dynamics into a series of slow and fast moving orthogonal co ...

Myocardial Motion Analysis and Visualization from Echocardiograms

Michaël Unser, Michael Sühling, Muthuvel Arigovindan

We present a new framework to estimate and visualize heart motion from echocardiograms. For velocity estimation, we have developed a novel multiresolution optical flow algorithm. In order to account for typical heart motions like contraction/expansion and ...
