Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Gauge Transformations, Twisted Poisson Brackets and Hamiltonization of Nonholonomic Systems

In this paper we study the problem of Hamiltonization of nonholonomic systems from a geometric point of view. We use gauge transformations by 2-forms (in the sense of evera and Weinstein in Progr Theoret Phys Suppl 144:145 154 2001) to construct different ...

Ambient space formulations and statistical mechanics of holonomically constrained Langevin systems

John Maddocks

The most classic approach to the dynamics of an n-dimensional mechanical system constrained by d independent holonomic constraints is to pick explicitly a new set of (n - d) curvilinear coordinatesparametrizingthe manifold of configurations satisfying the ...

Motion Synergies for Real-Time Postural Control in Virtual Environments

Daniel Raunhardt

Virtual prototyping has become an important part during the product development process. The common way to let a user interact with the virtual prototype is the use of a three dimensional virtual mannequin that is controlled by the user. These human figure ...

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 ...

A Hamilton-Jacobi Formulation for Cooperative Control of Multi-Agent Systems

Denis Gillet, Sylvain Rudaz, Hajir Roozbehani

Coordination of autonomous non-point agents is studied in this work. Interactions between vehicles together with their internal dynamics have been modeled as a continuous, unconstrained differential game. In particular, collision prediction is shown to be ...

Refactoring OCL Annotated UML Class Diagrams

Slavisa Markovic

Refactoring of UML class diagrams is an emerging research topic and heavily inspired by refactoring of program code written in objectoriented implementation languages. Current class diagram refactoring techniques concentrate on the diagrammatic part but ne ...

Measurement-based optimization of batch processes with terminal constraint

Carsten Welz

This thesis deals with dynamic optimization of batch processes, i.e. processes that are characterized by a finite time of operation and the frequent repetition of batches. The objective is to maximize the quantity of the desired product at final time while ...

Interactive identification of the center of mass reachable space for an articulated manipulator

Ronan Boulic

We propose an efficient kinematic position control for the center of mass of an articulated arm. The algorithm integrates the context of multiple joints reaching their limit value together with a singular configuration on the remaining joint space. We demo ...
