Semilocal smoothihg S-splines [PDF]

open access: yesКомпьютерные исследования и моделирование, 2010
Semilocal smoothing splines or S-splines from class C p are considered. These splines consist of polynomials of a degree n, first p + 1 coefficients of each polynomial are determined by values of the previous polynomial and p its derivatives at the point

Bounds for the sums of zeros of solutions of $u^{(m)}=P(z)u$ where $P$ is a polynomial

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
The main purpose of this paper is to consider the differential equation $u^{(m)}=P(z)u$ $(m\geq 2)$ where $P$ is a polynomial with in general complex coefficients. Let $z_{k}(u),$ $k=1,2,\ldots$ be the zeros of a nonzero solution $u$ to that equation. We

New Polynomial Bounds for Jordan’s and Kober’s Inequalities Based on the Interpolation and Approximation Method

open access: yesMathematics, 2019
In this paper, new refinements and improvements of Jordan’s and Kober’s inequalities are presented. We give new polynomial bounds for the s i n c ( x ) and cos ( x ) functions based on the interpolation and approximation ...

Polynomial, Neural Network, and Spline Wavelet Models for Continuous Wavelet Transform of Signals

open access: yesSensors, 2021
In this paper a modified wavelet synthesis algorithm for continuous wavelet transform is proposed, allowing one to obtain a guaranteed approximation of the maternal wavelet to the sample of the analyzed signal (overlap match) and, at the same time, a ...

Proposal New S-box for AES Algorithm Depend on A.I Bee Colony [PDF]

open access: yesEngineering and Technology Journal, 2015
The AES algorithm, also called the Rijndael algorithm, is a symmetric block cipher, where the data are encrypted/ decrypted in blocks of 128 bits. Each data block is modified by several rounds of processing, where each round involves four steps.
