Boundary problem for the singular heat equation
Karpatsʹkì Matematičnì Publìkacìï, 2017 The scheme for solving of a mixed problem with general boundary conditions is proposed for a heat equation \[a(x)\frac{\partial T}{\partial \tau}= \frac{\partial}{\partial x} \left(\lambda(x)\frac{\partial T}{\partial x}\right)\] with coefficient $a(x ...

Vibration of a Flexible Hanging Chain with a Mass on the End in a Nonstationary Regime of the Motion Mechanism in Hoisting Machines [PDF]
Journal of Applied and Computational MechanicsThe article is focused on the vibrations of a heavy chain with a mass on the end when the hoisting machines are in a nonstationary regime of motion, assuming that motor or brake torque is a linear function of the speed of the motion mechanism.

Automatic Gait Recognition via Fourier Descriptors of Deformable Objects
, 2003 We describe a new method for Automatic Gait Recognition based around the use of Fourier descriptors that model the periodic deformation of human gait. Fourier descriptors have been used successfully in the past to model the boundary of static or moving ...

Second boundary-value problem for the generalized Aller–Lykov equation
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019 The equations that describe a new type of wave motion arise in the course of mathematical modeling for continuous media with memory. This refers to differential equations of fractional order, which form the basis for most mathematical models describing a

Two-dimensional local Fourier image reconstruction via domain decomposition Fourier continuation method. [PDF]
PLoS ONE, 2019 The MRI image is obtained in the spatial domain from the given Fourier coefficients in the frequency domain. It is costly to obtain the high resolution image because it requires higher frequency Fourier data while the lower frequency Fourier data is less

New method for renormalon subtraction using Fourier transform
Physics Letters B, 2021 To improve accuracy in calculating QCD effects, we propose a method for renormalon subtraction in the context of the operator-product expansion. The method enables subtracting renormalons of various powers in ΛQCD efficiently and simultaneously from ...

A Fourier pseudospectral method for some computational aeroacoustics problems
, 2006 A Fourier pseudospectral time-domain method is applied to wave propagation problems pertinent to computational aeroacoustics. The original algorithm of the Fourier pseudospectral time-domain method works for periodical problems without the interaction ...
