Resolution Enhancement by Prediction of the High-Frequency Image Based on the Laplacian Pyramid
EURASIP Journal on Advances in Signal Processing, 2006 According to recent advances in digital image processing techniques, interest in high-quality images has been increased. This paper presents a resolution enhancement (RE) algorithm based on the pyramid structure, in which Laplacian histogram matching is

Eigenvalue problems with p-Laplacian operators
Electronic Journal of Differential Equations, 2014 In this article, we study eigenvalue problems with the p-Laplacian operator: $$ -(|y'|^{p-2}y')'= (p-1)(\lambda\rho(x)-q(x))|y|^{p-2}y \quad \text{on } (0,\pi_{p}), $$ where p>1 and $\pi_{p}\equiv 2\pi/(p\sin(\pi/p))$.

Hypergraph p-Laplacians and Scale Spaces
Journal of Mathematical Imaging and VisionAbstractThe aim of this paper is to revisit the definition of differential operators on hypergraphs, which are a natural extension of graphs in systems based on interactions beyond pairs. In particular, we focus on the definition of Laplacian and p-Laplace operators for oriented and unoriented hypergraphs, their basic properties, variational structure,

International Journal of Robust and Nonlinear Control, EarlyView., 2023 Abstract We propose a hierarchical energy management scheme for aggregating Distributed Energy Resources (DERs) for grid flexibility services. To prevent a direct participation of numerous prosumers in the wholesale electricity market, aggregators, as self‐interest agents in our scheme, incentivize prosumers to provide flexibility. We firstly model the

Uniqueness and stability of solutions without the boundary condition
Boundary Value Problems, 2019 A parabolic equation related to the p-Laplacian is considered. If the equation is degenerate on the boundary, then demonstrating the regularity on the boundary is difficult, the trace on the boundary cannot be defined, in general.

Chemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.In CH2X2 (X=Cl, Br, and I) molecules, the magnitude of σ‐hole on the X atom decreases from CH2I2 to CH2Cl2 . Three different types of interactions i. e., C−X⋅⋅⋅O halogen bond, and C−H⋅⋅⋅O and O−H⋅⋅⋅X hydrogen bond, are possible in [CH3OH−CH2X2] complexes.
