Proper efficiency and duality for a new class of nonconvex multitime multiobjective variational problems [PDF]
, 2014 In this paper, a new class of generalized of nonconvex multitime multiobjective variational problems is considered. We prove the sufficient optimality conditions for efficiency and proper efficiency in the considered multitime multiobjective variational ...

Infant Mental Health Journal: Infancy and Early Childhood, Volume 42, Issue 1, Page 21-34, January/February 2021., 2021 ABSTRACT Parental reflective functioning (PRF) is an important predictor of infant attachment, and interventions that target parent–infant/toddler dyads who are experiencing significant problems have the potential to improve PRF. A range of dyadic interventions have been developed over the past two decades, some of which explicitly target PRF as part ...

An Efficient Nonconvex Regularization Method for Wavelet Frame Based Compressed Sensing Recovery
Journal of Computations & Modelling, 2021 In this paper, we propose a variation model which takes advantage of the wavelet tight frame and nonconvex shrinkage penalties for compressed sensing recovery.

A Nonlocal Model for Reconstructing Images Corrupted by Cauchy Noise
Moroccan Journal of Pure and Applied Analysis, 2023 The aim of this paper is to present the mathematical and numerical study of a nonlocal nonlinear model based on the variable exponent p(x)-Laplacian for removing Cauchy noise, which is a type of impulsive and non-Gaussian degradation.

Using Tropical Optimization Techniques to Evaluate Alternatives via Pairwise Comparisons [PDF]
International Conference on Scientific Computing, 2015 We propose a new approach to solve the problem of rating alterna-tives based on their pairwise comparison. The problem is formulatedin terms of tropical algebra, and then reduced to the approximationof pairwise comparison matrices by reciprocal matrices ...

SOLVING HIGHER-ORDER INTEGRO DIFFERENTIAL EQUATIONS BY VIM AND MHPM
, 2020 In this paper, the Variational Iteration Method (VIM) and Modified Homotopy Perturbation Method (MHPM) are applied to solve boundary value problems for higher-order Volterra integro-differential equations.

Higher Order Variational Integrators: a polynomial approach [PDF]
, 2013 We reconsider the variational derivation of symplectic partitioned Runge-Kutta schemes. Such type of variational integrators are of great importance since they integrate mechanical systems with high order accuracy while preserving the structural ...
