Different adaptive modified riesz mean filter for high-density salt-and-pepper noise removal in grayscale images [PDF]
, 2021 This paper proposes a new filter, Different Adaptive Modified Riesz Mean Filter (DAMRmF), for high-density salt-and-pepper noise (SPN) removal. DAMRmF operationalizes a pixel weight function and adaptivity condition of Adaptive Median Filter (AMF).

Variation in the Oxidative State of Collared Flycatcher (<i>Ficedula albicollis</i>) Nestlings and Its Association With Their Plumage Coloration. [PDF]
Ecol EvolPlumage coloration is widely recognized as an important component in intraspecific communication. Our aim was to examine the variation of oxidative parameters and their associations with the coloration of two different nestling plumage traits in collared flycatchers (Ficedula albicollis).

On the domain of Riesz mean in the space Ls
Filomat, 2017 Let 0 < s < ?. In this study, we introduce the double sequence space Rqt(Ls) as the domain of four dimensional Riesz mean Rqt in the space Ls of absolutely s-summable double sequences. Furthermore, we show that Rqt(Ls) is a Banach space and a barrelled space for 1 ? s < 1 and is not a barrelled space for 0 < s < 1.

Fractional Schrödinger Equation in the Presence of the Linear Potential
Mathematics, 2016 In this paper, we consider the time-dependent Schrödinger equation: i ∂ ψ ( x , t ) ∂ t = 1 2 ( − Δ ) α 2 ψ ( x , t ) + V ( x ) ψ ( x , t ) , x ∈ R , t > 0 with the Riesz space-fractional derivative of order ...

Riesz means on homogeneous trees [PDF]
Concrete Operators, 2021 Abstract Let 𝕋 be a homogeneous tree. We prove that if f ∈ Lp (𝕋), 1 ≤ p ≤ 2, then the Riesz means Sz R (f) converge to f everywhere as R → ∞, whenever Re z > 0.

Hierarchical Riesz bases for Hs(Omega), 1 < s < 5/2 [PDF]
, 2005 On arbitrary polygonal domains $Omega subset RR^2$, we construct $C^1$ hierarchical Riesz bases for Sobolev spaces $H^s(Omega)$. In contrast to an earlier construction by Dahmen, Oswald, and Shi (1994), our bases will be of Lagrange instead of Hermite ...

A maximal Riesz-Kantorovich theorem with applications to markets with an arbitrary commodity set
Математичні СтудіїBy analyzing proofs of the classical Riesz-Kantorovich theorem, the Mazón-Segura de León theorem on abstract Uryson operators and the Pliev-Ramdane theorem on C-bounded orthogonally additive operators on Riesz spaces, we find the most general (to our ...

Carleson Measures and Logvinenko-Sereda sets on compact manifolds [PDF]
, 2013 Given a compact Riemannian manifold $M$ of dimension $m \geq 2$, we study the space of functions of $L^2(M)$generated by eigenfunctions of eigenvalues less than $L \geq 1$ associated to the Laplace-Beltrami operator on $M$.
