A Noise-Resistant Mixed-Discrete Particle Swarm Optimization Algorithm for the Automatic Design of Robotic Controllers
Alcherio Martinoli, Cyrill Silvan Baumann
The automatic design of well-performing robotic controllers is still an unsolved problem due to the inherently large parameter space and noisy, often hard-to-define performance metrics, especially when sequential tasks need to be accomplished. Distal contr ...
2022A Novel Method for Detecting Unidentified Falling Object Loss Patterns in the LHC
Frédéric Blanc, Davide Di Croce, Tatiana Pieloni, Jorg Wenninger, Loïc Thomas Davies Coyle
Understanding and mitigating particle losses in the Large Hadron Collider (LHC) is essential for both machine safety and efficient operation. Abnormal loss distributions are tell- tale signs of abnormal beam behaviour or incorrect machine configuration. By ...
Journals of Accelerator Conferences Website (JACoW) 2022Leibniz en Créateur. Un regard matériel sur sa machine à calculer
Simon François Dumas Primbault
Between 1671 and 1716, the German mathematician Gottfried Wilhelm Leibniz attempted to design a reckoning machine. Working closely with the Parisian clockmaker Monsieur Ollivier, Leibniz eventually failed at producing a working prototype. After the redisco ...
2022Torque Computation With the Isogeometric Mortar Method for the Simulation of Electric Machines
Bernard Kapidani, Rafael Vazquez Hernandez
In this work, isogeometric mortaring is used for the simulation of a six-pole permanent magnet synchronous machine. Isogeometric mortaring is especially well suited for the efficient computation of rotating electric machines, as it allows for an exact geom ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022A Time Encoding Approach to Training Spiking Neural Networks
While Spiking Neural Networks (SNNs) have been gaining in popularity, it seems that the algorithms used to train them are not powerful enough to solve the same tasks as those tackled by classical Artificial Neural Networks (ANNs).In this paper, we provide ...
IEEE2022Efficiency Optimisation of Slotless Magnetic Bearing Machines
Yves Perriard, Douglas Martins Araujo, Leopoldo Rossini, Guzmán Borque Gallego
Efficiency is one of the key performance indexes in the design of electric motors. When considering fully active magnetic bearing machines, this aspect gain further relevance due to the necessity of actively controlling all the remaining degrees of freedom ...
2021La phénoménotechnique questionnée par la médiation. L'exemple du showroom du Larsim.
The purpose of this article is to present a space of mediation developed by the astrophysicist Vincent Minier and the philosopher Vincent Bontems at the Commissariat à l’Énergie atomique et aux Énergies renouvelables. This room, called “showroom”, promotes ...
Presses universitaires du Midi2020System Support for Efficient Replication in Distributed Systems
Current online applications, such as search engines, social networks, or file sharing services, execute across a distributed network of machines. They provide non-stop services to their users despite failures in the underlying network. To achieve such a hi ...
EPFL2019Using the new VPMADD instructions for the new post quantum key encapsulation mechanism SIKE
This paper demonstrates the use of new processor instructions VPMADD, intended to appear in the coming generation of Intel processors (codename "Cannon Lake"), in order to accelerate the newly proposed key encapsulation mechanism (KEM) named SIKE. SIKE is ...
IEEE COMPUTER SOC2019Multi-channel Time Encoding for Improved Reconstruction of Bandlimited Signals
Martin Vetterli, Adam James Scholefield, Karen Adam
Traditional sampling involves encoding a signal through (time, value)-pairs. In contrast, time encoding machines (TEMs) characterize a signal by recording time points which depend on the integral of the signal over time. We study multi-channel TEMs where c ...
