Optimizing Dynamic Aperture Studies with Active Learning
Davide Di Croce, Tatiana Pieloni, Ekaterina Krymova, Massimo Giovannozzi
Dynamic aperture is an important concept for the study of non-linear beam dynamics in circular accelerators. It describes the extent of the phase-space region where a particle's motion remains bounded over a given number of turns. Understanding the feature ...
2024Measurement in the Age of Information
Marilyne Andersen, Forrest Simon Webler
Information is the resolution of uncertainty and manifests itself as patterns. Although complex, most observable phenomena are not random and instead are associated with deterministic, chaotic systems. The underlying patterns and symmetries expressed from ...
2022Neural Energy Casimir Control for Port-Hamiltonian Systems
Giancarlo Ferrari Trecate, Muhammad Zakwan, Liang Xu
The energy Casimir method is an effective controller design approach to stabilize port-Hamiltonian systems at a desired equilibrium. However, its application relies on the availability of suitable Casimir and Lyapunov functions, whose computation are gener ...
2022Design of a Flexure Based Low Frequency Foucault Pendulum
Simon Nessim Henein, Ilan Vardi, Patrick Robert Flückiger
The Foucault pendulum is a well-known mechanism used to demonstrate the rotation of the Earth. It consists in a pendulum launched on linear orbits and, following Mach’s Principle, this line of oscillation will remain fixed with respect to absolute space bu ...
2020Foucault pendulum properties of spherical oscillators
Simon Nessim Henein, Ilan Vardi, Patrick Robert Flückiger
In 1851 Léon Foucault created a sensation with his pendulum providing a direct demonstration of the turning of the Earth. This simple device consists of a pendulum which is launched in a purely planar orbit. Following Mach's principle of inertia, the mass ...
euspen2020Local Vulnerabilities and Global Robustness of Coupled Dynamical Systems on Complex Networks
Coupled dynamical systems are omnipresent in everyday life. In general, interactions between
individual elements composing the system are captured by complex networks. The latter
greatly impact the way coupled systems are functioning and evolving in time. ...
EPFL2020Sliding Mode Control in Ziegler’s Pendulum With Tracking Force: Novel Modeling Considerations
Mehran Khaghani, Ehsan Sarshari
Ziegler's pendulum is an appropriate model of a nonconservative dynamic system. By considering gravity effect, new equations of motion are extracted from Newton's motion laws. The instability of equilibriums is determined by linear stability analysis. Chao ...
