Tessellation and lmprovement of Simplicial Meshes using Neural Networks
Modern mesh generation addresses the development of robust algorithms that construct a discrete representation of the geometry into polytopal elements conforming to divergent properties: (i) fidelity to complex geometrical features, (ii) support for high s ...
EPFL2021Reactive Navigation in Crowds for Non-holonomic Robots with Convex Bounding Shape
Aude Billard, Diego Felipe Paez Granados, David Julian Gonon
This paper describes a novel method for non-holonomic robots of convex shape to avoid imminent collisions with moving obstacles. The method's purpose is to assist navigation in crowds by correcting steering from the robot's path planner or driver. We evalu ...
2021How to teach neural networks to mesh: Application on 2-D simplicial contours
François Avellan, Pascal Clausen, Alexis Papagiannopoulos
A machine learning meshing scheme for the generation of 2-D simplicial meshes is proposed based on the predictions of neural networks. The data extracted from meshed contours are utilized to train neural networks which are used to approximate the number of ...
2021A projected super-penalty method for the C1-coupling of multi-patch isogeometric Kirchhoff plates
Annalisa Buffa, Luca Coradello
This work focuses on the development of a super-penalty strategy based on the L2-projection of suitable coupling terms to achieve C1-continuity between non-conforming multi-patch isogeometric Kirchhoff plates. In particular, the choice of penalty parameter ...
2021A Coarse-mesh Methodology for the Analysis of One and Two-phase Nuclear Reactor Thermal-hydraulics in a Multi-physics Context
The analysis of nuclear reactors for performance and safety assessment benefits from the use of computational tools. In this context, this work aims at the development and application of a thermal-hydraulics methodology and related software that respond to ...
EPFL2021Virtual Capacitor Concept for Effective Real-Time MMC Simulations
Drazen Dujic, Stefan Milovanovic, Min Luo
In this paper, the real-time simulation model of the modular multilevel converter was split into several independent parts through the use of the virtual capacitor concept. As a result, the number of state-space matrices the real-time solver needs to take ...
2021A Validation Roadmap of Multi-Physics Simulators of the Resonator of MW-Class CW Gyrotrons for Fusion Applications
Stefano Alberti, Francisco Sanchez, Konstantinos Avramidis
For a few years the multi-physics modelling of the resonance cavity (resonator) of MW-class continuous-wave gyrotrons, to be employed for electron cyclotron heating and current drive in magnetic confinement fusion machines, has gained increasing interest. ...
MDPI2021Multi-View Triangulation: Systematic Comparison and an Improved Method
Triangulation is an important task in the 3D reconstruction of computer vision. It seems simple to find the position of a point in 3D space when its 2D perspective projections in multi-view images are given and the corresponding camera projection matrices ...
2020Pedestrian Intention Prediction: A Multi-task Perspective
Alexandre Massoud Alahi, Saeed Saadatnejad
In order to be globally deployed, autonomous cars must guarantee the safety of pedestrians. This is the reason why forecasting pedestrians' intentions sufficiently in advance is one of the most critical and challenging tasks for autonomous vehicles. This w ...
2020GarNet++: Improving Fast and Accurate Static 3D Cloth Draping by Curvature Loss
Pascal Fua, Mathieu Salzmann, Victor Constantin, Shaifali Parashar, Erhan Gündogdu
In this paper, we tackle the problem of static 3D cloth draping on virtual human bodies. We introduce a two-stream deep network model that produces a visually plausible draping of a template cloth on virtual 3D bodies by extracting features from both the b ...
