Hermite–Hadamard integral inequalities for log–convex interval–valued functions on co–ordinates [PDF]

open access: yes, 2022
In this paper, we give the notion of interval-valued log–convex functions on the co-ordinates on the rectangle from the plane. We establish Hermite-Hadamard and related inequalities for these classes of functions.

ADMM‐EM Method for L1‐Norm Regularized Weighted Least Squares PET Reconstruction

open access: yesComputational and Mathematical Methods in Medicine, Volume 2016, Issue 1, 2016., 2016
The L1‐norm regularization is usually used in positron emission tomography (PET) reconstruction to suppress noise artifacts while preserving edges. The alternating direction method of multipliers (ADMM) is proven to be effective for solving this problem.
