Global existence for perturbations of the 2D stochastic Navier-Stokes equations with space-time white noise
We prove global in time well-posedness for perturbations of the 2D stochastic Navier-Stokes equations partial derivative( t)u + u center dot del u = Delta u - del p + sigma + xi, u(0, center dot ) = u(0),div (u) = 0, driven by additive space-time white noi ...
London2024Analysis of a Class of Multilevel Markov Chain Monte Carlo Algorithms Based on Independent Metropolis–Hastings
Fabio Nobile, Juan Pablo Madrigal Cianci
In this work, we present, analyze, and implement a class of multilevel Markov chain Monte Carlo(ML-MCMC) algorithms based on independent Metropolis--Hastings proposals for Bayesian inverse problems. In this context, the likelihood function involves solving ...
2023Identifying invariant solutions of wall-bounded three-dimensional shear flows using robust adjoint-based variational techniques
Tobias Schneider, Omid Ashtari
Invariant solutions of the Navier-Stokes equations play an important role in the spatiotemporally chaotic dynamics of turbulent shear flows. Despite the significance of these solutions, their identification remains a computational challenge, rendering many ...
Cambridge2023Dual-Arm Control for Coordinated Fast Grabbing and Tossing of an Object
Aude Billard, Michael Bosongo Bombile
Picking up objects to toss them on a conveyor belt are activities generated on a daily basis in the industry. These tasks are still done largely by humans. This paper proposes a unified motion generator for a bimanual robotic systems that enables two 7 deg ...
2022Unfreezing Social Navigation: Dynamical Systems based Compliance for Contact Control in Robot Navigation
Aude Billard, Vaibhav Gupta, Diego Felipe Paez Granados
Large efforts have focused on ensuring that the controllers for mobile service robots follow proxemics and other social rules to ensure both safe and socially acceptable distance to pedestrians. Nonetheless, involuntary contact may be unavoidable when the ...
IEEE2022Force Adaptation in Contact Tasks with Dynamical Systems
Aude Billard, Mahdi Khoramshahi, Walid Amanhoud
In many tasks such as finishing operations, achieving accurate force tracking is essential. However, uncertainties in the robot dynamics and the environment limit the force tracking accuracy. Learning a compensation model for these uncertainties to reduce ...
