On the prediction of the induced damage by the start-up sequence of Francis turbines: On operational resilience framework
Mario Paolone, Christophe Nicolet, Elena Vagnoni, Martin Seydoux
The number of transient operations in hydraulic machinery connected to power grid, notably start-ups and shut-downs, has observed a substantial increase in recent decades, primarily driven by the global shift toward intermittent renewable energy sources. S ...
2024A unified framework for walking and running of bipedal robots
Ludovic Righetti, Elham Daneshmand
In this paper, we propose a novel framework capable of generating various walking and running gaits for bipedal robots. The main goal is to relax the fixed center of mass (CoM) height assumption of the linear inverted pendulum model (LIPM) and generate a w ...
IEEE2021A Low-Parametric Rhombic Microstructure Family for Irregular Lattices
New fabrication technologies have significantly decreased the cost of fabrication of shapes with highly complex geometric structure. One important application of complex fine-scale geometric structures is to create variable effective elastic material prope ...
ASSOC COMPUTING MACHINERY2020On compact representations of Voronoi cells of lattices
Matthias Schymura, Christoph Hunkenschröder
In a seminal work, Micciancio and Voulgaris (SIAM J Comput 42(3):1364-1391, 2013) described a deterministic single-exponential time algorithm for the closest vector problem (CVP) on lattices. It is based on the computation of the Voronoi cell of the given ...
SPRINGER HEIDELBERG2020A finite element framework based on bivariate simplex splines on triangle configurations
Recently, triangle configuration based bivariate simplex splines (referred to as TCB-spline) have been introduced to the geometric computing community. TCB-splines retain many attractive theoretic properties of classical B-splines, such as partition of uni ...

In a seminal work, Micciancio & Voulgaris (2010) described a deterministic single-exponential time algorithm for the Closest Vector Problem (CVP) on lattices. It is based on the computation of the Voronoi cell of the given lattice and thus may need exponen ...
SPRINGER INTERNATIONAL PUBLISHING AG2018Data-driven spatio-temporal discretization for pedestrian flow characterization
Michel Bierlaire, Marija Nikolic
We propose a novel approach to pedestrian flow characterization. The definitions of density, flow and velocity existing in the literature are extended through a data-driven spatio-temporal discretization framework. The framework is based on three-dimension ...

2016Modeling of percolation of globular-equiaxed grains in Al-Cu alloys
Michel Rappaz, Jean-Luc Desbiolles, Christophe Mondoux
A new mesoscopic model able to describe percolation of globular-equiaxed grains, highly relevant for hot tearing formation in castings, has been developed. This model is inspired from the granular model of Sistaninia et al. [1-5] that considers polyhedral ...
Iop Publishing Ltd2015Dynamic crack propagation in a heterogeneous ceramic microstructure, insights from a cohesive model
Seyedeh Mohadeseh Taheri Mousavi
Silicon nitride is a widely used industrial ceramic, specifically for dynamic loading applications because of its special mechanical and material properties. The investigation of the underlying mechanisms which lead to these properties is experimentally ch ...
