Applied Machine Learning Algorithms for Courtyards Thermal Patterns Accurate Prediction

Mathematics, 2021
Currently, there is a lack of accurate simulation tools for the thermal performance modeling of courtyards due to their intricate thermodynamics. Machine Learning (ML) models have previously been used to predict and evaluate the structural performance of

On the existence of solutions for a parabolic‐elliptic chemotaxis model with flux limitation and logistic source

Mathematical Methods in the Applied Sciences, Volume 46, Issue 8, Page 9252-9267, 30 May 2023., 2023
In this article, we study the existence of solutions of a parabolic‐elliptic system of partial differential equations describing the behaviour of a biological species “ u$$ u $$” and a chemical stimulus “ v$$ v $$” in a bounded and regular domain Ω$$ \Omega $$ of ℝN$$ {\mathbb{R}}^N $$.

Assessment of self-adapting local projection-based solvers for laminar and turbulent industrial flows

Journal of Mathematics in Industry, 2018
In this work, we study the performance of some local projection-based solvers in the Large Eddy Simulation (LES) of laminar and turbulent flows governed by the incompressible Navier–Stokes Equations (NSE).
