On the Expediency and Possibilities of Approximating a Pure Delay Link

open access: yesИнформатика и автоматизация, 2022
When solving problems of controlling an object with delay, it is often necessary to approximate a pure delay link with a minimum phase link in order to ensure the possibility of using analytical methods for regulator design.

Method Of Obtaining Approximate Formulas [PDF]

open access: yes, 2018
The two-parameter method of approximating the sum of a power series in terms of its first three terms of the expansion, which allows one to obtain analytic approximations of various functions, decomposes into a Maclaurin series.

Function Approximation through Fuzzy Systems Using Taylor Series Expansion-Based Rules: Interpretability and Parameter Tuning [PDF]

open access: yes, 2004
In this paper we present a new approach for the problem of approximating a function from a training set of I/O points using fuzzy logic and fuzzy systems. Such approach, as we will see, will provide us a number of advantages comparing to other more-limited systems.

Uniqueness, Born Approximation, and Numerical Methods for Diffuse Optical Tomography

open access: yesJournal of Applied Mathematics, 2013
Diffuse optical tomogrpahy (DOT) is to find optical coefficients of tissue using near infrared light. DOT as an inverse problem is described and the studies about unique determination of optical coefficients are summarized. If a priori information of the

Interaction of protons with nuclei in the Born approximation (II) [PDF]

open access: yesЯдерна фізика та енергетика
In the framework of the Born approximation, comparison of the previously used approaches, in which analytical expressions for the scattering amplitudes of particles by nuclei were obtained using the expansion of the potential into the series up to the ...

Propagation conditions of an eccentric crack in a semi-circular disk loaded in I+II mixed mode [PDF]

open access: yesMATEC Web of Conferences, 2020
Multi-parameter fracture mechanics concept is applied to investigate crack propagation conditions during a three-point bending (3PB) test performed on an asymmetrical semi-circular disk under I+II mixedmode loading.

Asymptotic enumeration of magic series [PDF]

open access: yes, 2013
A magic series is a set of natural numbers that, by virtue of its size, sum, and maximum value, could fill a row of a normal magic square. In this paper, we derive an exact two-dimensional integral representation for the number of magic series of order N.

Host movement, transmission hot spots, and vector-borne disease dynamics on spatial networks

open access: yesInfectious Disease Modelling, 2022
We examine how spatial heterogeneity combines with mobility network structure to influence vector-borne disease dynamics. Specifically, we consider a Ross-Macdonald-type disease model on n spatial locations that are coupled by host movement on a strongly

Prognostic Impact of Treatment Modalities, Including Targeted Compartmental Radio‐Immunotherapy, in a Cohort of Neuroblastoma Patients With CNS Metastases at Relapse

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neuroblastoma (NB) with central nervous system (CNS) metastases is rare at diagnosis, but occurs more often during relapse/progression. Patients with CNS metastases face a dismal prognosis, with no standardized curative treatment available.

Diophantine Approximation and Continued Fraction Expansions of Algebraic Power Series in Positive Characteristic

open access: yesJournal of Number Theory, 1997
The author finds the continued fraction expansion of some algebraic functions in characteristic \(p\). This allows him to deduce diophantine approximation properties of these algebraic functions. He recovers some interesting examples of \textit{M. W. Buck} and \textit{D. P. Robbins} [J.
