Mathematical Modeling of Hot-Air Drying of Osmo-dehydrated Nectarines
(De Gruyter, 2015-08)
The influence of osmotic pretreatment on nectarines with solutions of glucose syrup and sorbitol and subsequent dehydration at different temperatures (60°C, 70°C, or 80°C) was evaluated. The kinetics of moisture loss during ...
Modelling Diffusion Effects in Fertility Transition
Mathematical models bind theory to precise formulations, and by doing so accentuate logical inconsistences in theories and facilitate their testing. In this article we explore the implications of simple mathematical models ...
Kinetics of water diffusion in corn grain during the alkaline cooking at different temperatures and calcium hydroxide concentration
(J.L. Fernández-Muñoz, 2013-01-16)
Osmotic dehydration of apples in sugar/salt solutions: Concentration profiles and effective diffusion coefficients
(Elsevier B.V., 2010-10-01)
Apples (Fuji variety) were treated in aqueous sucrose (50% w/w) and salt (NaCl, 10% w/w) solutions for 2, 4 and 8 h (27 degrees C). Concentration profiles were determined as a function of the distance, considering the ...
On certain new exact solutions of a diffusive predator-prey system
We construct exact solutions for a system of two coupled nonlinear partial differential equations describing the spatio-temporal dynamics of a predator-prey system where the prey per capita growth rate is subject to the ...
A theoretical model of the diffusion process to spherical and isotropic fruits
(Timeland Publication, 2014-03)
Many models are using now in order to can study of the table green olives diffusion process. Different models had been consistent in order to determinate the magnitude order of the diffusion coefficient effectiveness; we ...
Detecção de bordas em imagens digitais através de um processo de difusão anisotrópica não linear
The edges detection model by a non-linear anisotropic diffusion, consists in a mathematical model of smoothing based in Partial Differential Equation (PDE), alternative to the conventional low-pass filters. The smoothing ...
