Correspondence functors and duality
A correspondence functor is a functor from the category of finite sets and correspondences to the category of k-modules, where k is a commutative ring. By means of a suitably defined duality, new correspondence functors are constructed, having remarkable p ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2023A convex set of robust D—stabilizing controllers using Cauchy's argument principle
Alireza Karimi, Philippe Louis Schuchert
A new approach is presented to obtain a convex set of robust D—stabilizing fixed structure controllers, relying on Cauchy's argument principle. A convex set of D—stabilizing controllers around an initial D—stabilizing controller for a multi-model set is re ...
Elsevier2022Annihilation Filter Approach For Estimating Graph Dynamics From Diffusion Processes
Pascal Frossard, Arun Venkitaraman
We propose an approach for estimating graph diffusion processes using annihilation filters from a finite set of observations of the diffusion process made at regular intervals. Our approach is based on the key observation that a graph diffusion process can ...
IEEE2022Positive moments for scattering amplitudes
Riccardo Rattazzi, Francesco Riva, Brando Bellazzini, Marc Riembau Saperas
We find the complete set of conditions satisfied by the forward 2 -> 2 scattering amplitude in unitary and causal theories. These are based on an infinite set of energy dependent quantities (the arcs) which are dispersively expressed as moments of a positi ...
AMER PHYSICAL SOC2021Localization of Electromagnetic Interference Sources Using a Time-Reversal Cavity
Marcos Rubinstein, Mohammad Azadifar, Amirhossein Mostajabi, Hamidreza Karami
In this article, we propose and implement a novel technique to locate electromagnetic interference (EMI) sources using the concept of time-reversal (TR) cavity. We show in an intuitive manner that reflections from the surfaces of a cavity can emulate an in ...
