Mathematics, 2022 The main aim of this article is to propose a general framework for the theoretical analysis of discrete schemes used to solve multi-dimensional parabolic problems with fractional power elliptic operators. This analysis is split into three parts.

On the fully discrete approximations of the MGT two-temperatures thermoelastic problem
Archives of Mechanics, 2022 We consider a one-dimensional two-temperatures thermoelastic model. The corresponding variational problem leads to a coupled system which is written in terms of the mechanical velocity, the temperature speed and the inductive temperature.

Approximate Discrete Reconstruction Algorithm [PDF]
Fundamenta Informaticae, 2013 Discrete tomography deals with tomographic reconstruction of greyscale images for which the set of possible grey levels is discrete and small. Here, we develop a discrete approximate reconstruction algorithm. Our algorithm computes an image that has only grey values belonging to a given finite set.

Optimal Control of Differential Inclusions, II: Sweeping
Известия Иркутского государственного университета: Серия "Математика", 2020 This paper is devoted to optimal control of dynamical systems governed by differential inclusions with discontinuous velocity mappings. This framework mostly concerns a new class of optimal control problems described by various versions of the socalled ...

Optimal Control of Differential Inclusions, I: Lipschitzian case
Известия Иркутского государственного университета: Серия "Математика", 2019 We develop the method of discrete approximations to study optimal control problems for differential inclusions by using advanced tools of variational analysis and generalized differentiation.

A continuous-time mathematical model and discrete approximations for the aggregation of β-Amyloid
Journal of Biological Dynamics, 2021 Alzheimer's disease is a degenerative disorder characterized by the loss of synapses and neurons from the brain, as well as the accumulation of amyloid-based neuritic plaques.

Low-Complexity Loeffler DCT Approximations for Image and Video Coding
Journal of Low Power Electronics and Applications, 2018 This paper introduced a matrix parametrization method based on the Loeffler discrete cosine transform (DCT) algorithm. As a result, a new class of 8-point DCT approximations was proposed, capable of unifying the mathematical formalism of several 8-point ...

Approximate Bayesian Computation for Discrete Spaces [PDF]
Entropy, 2021 Many real-life processes are black-box problems, i.e., the internal workings are inaccessible or a closed-form mathematical expression of the likelihood function cannot be defined. For continuous random variables, likelihood-free inference problems can be solved via Approximate Bayesian Computation (ABC).

Comparison of bulk properties of wet granular materials using different capillary force approximations [PDF]
EPJ Web of ConferencesWe perform Discrete Element Method simulations of wet granular matter in a split-bottom shear cell. To calculate the capillary forces from the liquid bridges between the grains, we used three different approximations.
