A free boundary model for transport-induced neurite growth

European Journal of Applied Mathematics
We introduce a free boundary model to study the effect of vesicle transport onto neurite growth. It consists of systems of drift-diffusion equations describing the evolution of the density of antero- and retrograde vesicles in each neurite coupled to ...

DETERMINATION OF THE EFFECTIVE PERMITTIVITY OF A HETEROGENEOUS MATERIAL

Electrical engineering & Electromechanics, 2020
Purpose. To develop a two-dimensional numerical-field model for determining the effective permittivity of a multicomponent material represented by a system of homogeneous volumes with known physical characteristics. Methodology. The model is based on the

Solución numérica de las ecuaciones de Navier-Stokes incompresibles por el método de los volúmenes finitos

Revista Ion, 2013
The main goal of this paper is the numerical solution of the Navier-Stokes equations for an incompressible flow. A numerical approach with a finite volume discretization technique and using the method of fractional stepsare presented to solver the ...

Efficient Methods to Calculate Partial Sphere Surface Areas for a Higher Resolution Finite Volume Method for Diffusion-Reaction Systems in Biological Modeling

Mathematical and Computational Applications, 2019
Computational models for multicellular biological systems, in both in vitro and in vivo environments, require solving systems of differential equations to incorporate molecular transport and their reactions such as release, uptake, or decay. Examples can

Multiscale Finite Volume Method For Finite-Volume-Based Poromechanics Simulations

Proceedings, 2018
We propose a multiscale finite volume method (MSFV) for simulation of coupled flow-deformation in heterogeneous porous media under elastic deformation (i.e., poroelastic model). The fine-scale fully resolved system of equations is obtained based on a conservative finite-volume method in which the displacement and pore pressure unknowns are located in a

Numerical Analysis of an Impact of Planned Location of Sewage Discharge on Natura 2000 Areas – The Dead Vistula Region Case Study

Polish Maritime Research, 2019
This article presents results of an analysis of impact of a designed discharge of contaminated water into the Dead Vistula (Wisła Martwa) in the region of the Isthmus (Przesmyk) with the aim of determination of a possible effect of the pollution onto ...

Analysis of finite volumes and integral transform solutions for thermally developing non-Newtonian fluid flow

Vetor, 2010
The current work provides a comparison between two different methodologies for solving convection-diffusion problems: the Generalized Integral Transform Technique (GITT) and the Finite Volumes Method (FVM).

Study of natural ventilation in a Gothic multi-tunnel greenhouse designed to produce rose (Rosa spp.) in the high-Andean tropic

Ornamental Horticulture, 2019
In tropical regions the production of ornamentals is developed exclusively in naturally ventilated plastic greenhouses, which sometimes leads to inappropriate microclimates with high temperatures and humidity that limit the productive development of ...
