Simple biset functors and double Burnside ring

Let G be a finite group and let k be a field. Our purpose is to investigate the simple modules for the double Burnside ring kB(G,G). It turns out that they are evaluations at G of simple biset functors. For a fixed finite group H, we introduce a suitable b ...

Force and Torque Analytical Models of a Reaction Sphere Actuator Based on Spherical Harmonic Rotation and Decomposition

Yves Perriard, Leopoldo Rossini

This paper presents an analytical model for the force and torque developed by a reaction sphere actuator for satellite attitude control. The reaction sphere is an innovative momentum exchange device consisting of a magnetic bearings spherical rotor that ca ...

Inkjet Printed Conductive Polymer Electrodes for AC Electroosmosis

Nico de Rooij, Danick Briand, Jérôme Courbat, Luca Ribetto

Standalone integrated microfuidic systems require pumping elements. Electro-osmosis (EO) is an e"ective method of actuating liquids [1,2]. ACEO exploits much lower potentials and, by using alternating fields, overcomes the issues of electrolysis and gas ge ...

L'équation de rappel

Olivier Kneuss

In this thesis we are interested in the following problem : given two differential k–forms g and f, most of the time they will be assumed closed, on what conditions can we pullback g to f by a map φ ? In other words we ask when it is possible to solve the ...

Blob current structures in TORPEX plasmas: experimental measurements and numerical simulations

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Nicola Vianello, Davoud Iraji, Diane Virginie Marie Lançon

In the simple magnetized torus TORPEX, field-aligned blobs originate from ideal interchange waves and propagate radially outward due to del B and curvature induced drifts. Time-resolved two-dimensional measurements of the field-aligned current density J(pa ...

Compressive Sensing under Matrix Uncertainties: An Approximate Message Passing Approach

Volkan Cevher

In this work, we consider a general form of noisy compressive sensing (CS) when there is uncertainty in the measurement matrix as well as in the measurements. Matrix uncertainty is motivated by practical cases in which there are imperfections or unknown ca ...

The derivatives of the SEDS optimization cost function and constraints with respect to the learning parameters

Aude Billard, Seyed Mohammad Khansari Zadeh

This technical report provides supplementary information for the optimization problems defined for Stable Estimator of Dynamical Systems (SEDS). Reading of this report is not necessary for researchers who only want to use SEDS learning algorithm. The repor ...

Origami - geometry of folded plate structures

Yves Weinand, Hans Ulrich Buri

This research proposes new methods to generate rapidly complex folded plate structures that can be built with cross laminated timber panels. Composition and dimensions of these panels as well as the possibility to mill them by Computer Numerically Controll ...

Universal Bounds And Semiclassical Estimates For Eigenvalues Of Abstract Schrodinger Operators

Joachim Stubbe

We prove trace inequalities for a self-adjoint operator on an abstract Hilbert space, which extend those known previously for Laplacians and Schrodinger operators, freeing them from restrictive assumptions on the nature of the spectrum and allowing operato ...

Novel Library of Logic Gates with Ambipolar CNTFETs: Opportunities for Multi-Level Logic Synthesis

Giovanni De Micheli, Mohamed Haykel Ben Jamaa

This paper exploits the unique in-ﬁeld controllability of the device polarity of ambipolar carbon nanotube ﬁeld effect transistors (CNTFETs) to design a technology library with higher expressive power than conventional CMOS libraries. Based on generalized ...
