A semidiscrete scheme for evolution equations with memory
Discrete & Continuous Dynamical Systems - A, 2019 We introduce a new mathematical framework for the time discretization of evolution equations with memory. As a model, we focus on an abstract version of the equation partial derivative(t)u(t) - integral(infinity)(0) g(s)Delta u(t - s) ds = 0 with Dirichlet boundary conditions, modeling hereditary heat conduction with Gurtin-Pipkin thermal law.

Fitted Tension Spline Scheme for a Singularly Perturbed Parabolic Problem With Time Delay
Journal of Applied Mathematics, Volume 2024, Issue 1, 2024.A fitted tension spline numerical scheme for a singularly perturbed parabolic problem (SPPP) with time delay is proposed. The presence of a small parameter ε as a multiple of the diffusion term leads to the suddenly changing behaviors of the solution in the boundary layer region.

Advances in Mathematical Physics, Volume 2024, Issue 1, 2024.In this paper, a numerical scheme for a time‐dependent singularly perturbed parabolic convection–diffusion problem with boundary turning points is presented. The problem exhibits a left boundary layer in the spatial domain. We use the Crank–Nicolson method for temporal discretization and a nonstandard finite difference approach for spatial ...

Semi-Discretization of a Euler-Bernoulli Beam and Its Application to Motion Planning
IEEE AccessWe consider a Euler-Bernoulli beam with sliding cantilever boundary conditions at both ends. The control input to the beam is the force acting on one of the cantilevers.

Semidiscrete optimal transport with unknown costs
, 2023 Semidiscrete optimal transport is a challenging generalization of the classical transportation problem in linear programming. The goal is to design a joint distribution for two random variables (one continuous, one discrete) with fixed marginals, in a way that minimizes expected cost.

Parallel processors and nonlinear structural dynamics algorithms and software [PDF]
An explicit-explicit subcycling procedure for the finite element analysis of structural dynamics is developed. This procedure has relaxed the usual constraint of requiring integer time step ratios for adjacent nodal groups.

Image Processing in the Semidiscrete Group of Rototranslations [PDF]
, 2015 It is well-known, since [12], that cells in the primary visual cortex V1 do much more than merely signaling position in the visual field: most cortical cells signal the local orientation of a contrast edge or bar – they are tuned to a particular local orientation.

Integrability of the derivative of solutions to a singular one-dimensional parabolic problem
, 2017 We study integrability of the derivative of solutions to a singular one-dimensional parabolic equation with initial data in $W^{1,1}$. In order to avoid additional difficulties we consider only the periodic boundary conditions.
