Matrix of Polynomials Model based Polynomial Dictionary Learning Method for Acoustic Impulse Response Modeling [PDF]
, 2017 We study the problem of dictionary learning for signals that can be represented as polynomials or polynomial matrices, such as convolutive signals with time delays or acoustic impulse responses.

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

Polynomial Relations between Polynomial Roots
Journal of Algebra, 1995 Let \(f\) be a separable polynomial of degree \(n\) over a field \(K\) and let \(G\) be the Galois group of its splitting field. It has been shown by \textit{C. J. Smyth} [J. Number Theory 23, 243-254 (1986; Zbl 0586.12001)]\ that if \(G= S_n\) and the characteristic of \(K\) either is zero or exceeds \(n\), then there are no non-trivial additive ...

A Penrose polynomial for embedded graphs [PDF]
, 2011 We extend the Penrose polynomial, originally defined only for plane graphs, to graphs embedded in arbitrary surfaces. Considering this Penrose polynomial of embedded graphs leads to new identities and relations for the Penrose polynomial which can not be

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