Experimental observation of topological transition in linear and nonlinear parametric oscillators
Romain Christophe Rémy Fleury, Benjamin Apffel
Parametric oscillators are examples of externally driven systems that can exhibit two stable states with opposite phase depending on the initial conditions. In this work, we propose to study what happens when the external forcing is perturbed by a continuo ...
2024Geometric Learning: Leveraging differential geometry for learning and control
In this thesis, we concentrate on advancing high-level behavioral control policies for robotic systems within the framework of Dynamical Systems (DS). Throughout the course of this research, a unifying thread weaving through diverse fields emerges, and tha ...
EPFL2024A Versatile Approach to Stabilize Liquid-Liquid Interfaces using Surfactant Self-Assembly
Stabilizing liquid-liquid interfaces, whether between miscible or immiscible liquids, is crucial for a wide range of applications, including energy storage, microreactors, and biomimetic structures. In this study, a versatile approach for stabilizing the w ...
Wiley-V C H Verlag Gmbh2024Social-Transmotion: Promptable Human Trajectory Prediction
Alexandre Massoud Alahi, Yang Gao, Kaouther Messaoud Ben Amor, Saeed Saadatnejad
Accurate human trajectory prediction is crucial for applications such as autonomous vehicles, robotics, and surveillance systems. Yet, existing models often fail to fully leverage the non-verbal social cues human subconsciously communicate when navigating ...
2024Long live(d) CsPbBr3 superlattices: colloidal atomic layer deposition for structural stability
Raffaella Buonsanti, Philippe Benjamin Green, Alexander Nicolas Chen, Victoria Lapointe
Superlattice formation afforded by metal halide perovskite nanocrystals has been a phenomenon of interest due to the high structural order induced in these self-assemblies, an order that is influenced by the surface chemistry and particle morphology of the ...
Cambridge2024System for predicting a prognosis of the neuropsychological and/or neuropsychiatric status in a subject
The present invention relates to systems and methods for predicting a prognosis of the neuropsychological and/or neuropsychiatric status in a subject based on reports of Minor Hallucination (MH) events in combination with electrophysiological data of the s ...
2024Optimality principles for the analysis of biological processes across scales: From enzyme kinetics to microbiome dynamics
Microorganisms are essential for life on Earth, performing key roles in numerous biological processes. Their influence extends across a wide spectrum, from human health and ecological balance to advancements in biotechnology and industrial applications. Th ...
EPFL2024Roughness Evolution Induced by Third-Body Wear
Jean-François Molinari, Antonio Joaquin Garcia Suarez, Tobias Brink
Surface roughness is a key factor when it comes to friction and wear, as well as to other physical properties. These phenomena are controlled by mechanisms acting at small scales, in which the topography of apparently flat surfaces is revealed. Roughness i ...
New York2024Less Conservatism, Stronger Robustness: Iterative Robust Gain-Scheduled Path Following Control of Autonomous Bus With Unstructured and Changing Dynamics
Denis Gillet, Man Shi, Jianwei Li
Path-following control is a critical technology for autonomous vehicles. However, time-varying parameters, parametric uncertainties, external disturbances, and complicated environments significantly challenge autonomous driving. We propose an iterative rob ...
Ieee-Inst Electrical Electronics Engineers Inc2024Violation-aware contextual Bayesian optimization for controller performance optimization with unmodeled constraints
Colin Neil Jones, Bratislav Svetozarevic, Wenjie Xu
We study the problem of performance optimization of closed -loop control systems with unmodeled dynamics. Bayesian optimization (BO) has been demonstrated to be effective for improving closed -loop performance by automatically tuning controller gains or re ...
