On the Connection Coefficients of the Chebyshev-Boubaker Polynomials [PDF]

open access: yesThe Scientific World Journal, 2013
The Chebyshev-Boubaker polynomials are the orthogonal polynomials whose coefficient arrays are defined by ordinary Riordan arrays. Examples include the Chebyshev polynomials of the second kind and the Boubaker polynomials.

Connection coefficients of Shannon wavelets

open access: yesMathematical Modelling and Analysis, 2006
In this paper the differential properties of Shannon wavelets are investigated. The connection coefficients of Shannon wavelets are explicitly computed with a finite formula up to any order.

Integer composition, connection Appell constants and Bell polynomials [PDF]

open access: yesJournal of Numerical Analysis and Approximation Theory, 2021
We introduce an explicit form of the connection coefficients for Appell polynomial sequences via Toeplitz-Hessenberg matrix determinants. Generalizing, we give an explicit form of the connection coefficients for arbitrary   polynomial sequences and ...

Explicit generating series for connection coefficients [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
This paper is devoted to the explicit computation of generating series for the connection coefficients of two commutative subalgebras of the group algebra of the symmetric group, the class algebra and the double coset algebra. As shown by Hanlon, Stanley

On the Exact Evaluation of Integrals of Wavelets

open access: yesMathematics, 2023
Wavelet expansions are a powerful tool for constructing adaptive approximations. For this reason, they find applications in a variety of fields, from signal processing to approximation theory.

Long Cycle Factorizations: Bijective Computation in the General Case [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
This paper is devoted to the computation of the number of ordered factorizations of a long cycle in the symmetric group where the number of factors is arbitrary and the cycle structure of the factors is given. Jackson (1988) derived the first closed form

Bijective evaluation of the connection coefficients of the double coset algebra [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
This paper is devoted to the evaluation of the generating series of the connection coefficients of the double cosets of the hyperoctahedral group. Hanlon, Stanley, Stembridge (1992) showed that this series, indexed by a partition $ν$, gives the spectral ...

Numerical identification of position-dependent friction coefficients from measured displacement data in a bolt-nut connection

open access: yesResults in Engineering, 2023
Friction is a complex system affected by microscopical effects and multidisciplinary phenomena. Coulomb's simple friction model with a constant friction coefficient cannot account for all these tribological effects.

Modified localization coefficients for cluster processes identification: a comparative analysis (case study: the Russian rye sector) [PDF]

open access: yesE3S Web of Conferences, 2020
The paper presents the results of the identification of agrarian clusters. Research is done in connection with the rye sector of Russia taken as a case study. The localization coefficients were calculated from the gross yield of winter rye grain.

Sinc-Fractional Operator on Shannon Wavelet Space

open access: yesFrontiers in Physics, 2018
In this paper the sinc-fractional derivative is extended to the Hilbert space based on Shannon wavelets. Some new fractional operators based on wavelets are defined.
