Asymptotic behaviour of zeros of bieberbach polynomials [PDF]

open access: yes, 1990
Let Ω be a simply-connected domain in the complex plane and let πn denote the nth-degree Bieberbach polynomial approximation to the conformal map f of Ω onto a disc.

Modulation techniques for data superposition on amplitude-modulated signals [PDF]

open access: yes, 1983
Double-sideband amplitude-modulation is widely used because of its simplicity in transmission and reception, but in a number of applications the inclusion of a data channel has become an additional requirement.

On the zeros of the Macdonald functions [PDF]

open access: yesOpuscula Mathematica, 2019
We are concerned with the zeros of the Macdonald functions or the modified Bessel functions of the second kind with real index. By using the explicit expressions for the algebraic equations satisfied by the zeros, we describe the behavior of the zeros ...

On computing the zeros of periodic systems [PDF]

open access: yes, 2002
We present an effcient and numerically reliable approach to compute the zeros of a periodic system. The zeros are defined in terms of the transfer-function matrix corresponding to an equivalent lifted statespace representation as constant system.

Conditions for Undershoot Responses in Circular Path-Following Vehicle Control with the Rotational and Expansionary Coordinate Transformation

open access: yesNihon Kikai Gakkai ronbunshu, 2022
This paper discusses the conditions for the undershoot responses in a circular path-following vehicle control. As a method to follow the circular path, it is known to combine the rotational and expansionary coordinate transformation to the vehicle ...

On zeros of an entire function coinciding with exponential typequasi-polynomials, associated with a regular third-order differential operator on an interval

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2021
In this paper, we consider the question on study of zeros of an entire function of one class, which coincides with quasi-polynomials of exponential type.

On invariant zeros of linear systems of PDEs [PDF]

open access: yes, 2006
In this paper we provide a behavioral framework in which to describe and extend the concept of linear dynamics introduced by Fliess, from the one dimensional (1D) to the multidimensional (nD) framework.We provide an alternative description of the ...

Differential Equations Arising from the Generating Function of the (r, β)-Bell Polynomials and Distribution of Zeros of Equations

open access: yesMathematics, 2019
In this paper, we study differential equations arising from the generating function of the ( r , β ) -Bell polynomials. We give explicit identities for the ( r , β ) -Bell polynomials. Finally, we find the zeros of the ( r , &#
