Simultaneous occurrence of sliding and crossing limit cycles in piecewise linear planar vector fields [PDF]

open access: yes, 2019
In the present study we consider planar piecewise linear vector fields with two zones separated by the straight line $x=0$. Our goal is to study the existence of simultaneous crossing and sliding limit cycles for such a class of vector fields.

Chebyshev centers in normed spaces

open access: yesJournal of Approximation Theory, 1984
Let E be a normed linear space, F a bounded subset, Y a closed subset of E. A nonnegative real number \(r_ Y(F)\) is called the relative Chebyshev radius of F with respect to Y if \(r_ Y(F)\) is the infimum of all numbers \(r>0\) for which there exists a \(y\in Y\) such that F is contained in the closed ball B(y,r) with center y and radius r.

Discrete Fourier Analysis and Chebyshev Polynomials with $G_2$ Group [PDF]

open access: yes, 2012
The discrete Fourier analysis on the $30^{\degree}$-$60^{\degree}$-$90^{\degree}$ triangle is deduced from the corresponding results on the regular hexagon by considering functions invariant under the group $G_2$, which leads to the definition of four ...

Integrating geometries of ReLU feedforward neural networks

open access: yesFrontiers in Big Data, 2023
This paper investigates the integration of multiple geometries present within a ReLU-based neural network. A ReLU neural network determines a piecewise affine linear continuous map, M, from an input space ℝm to an output space ℝn.

A Minimax Unbiased Estimation Fusion in Distributed Multisensor Localization and Tracking

open access: yesInternational Journal of Distributed Sensor Networks, 2012
A minimax estimation fusion in distributed multisensor systems is proposed, which aims to minimize the worst-case squared estimation error when the cross-covariances between local sensors are unknown and the normalized estimation errors of local sensors ...
