Publicación A FIRST-ORDER TIME CONSTANT ESTIMATION FOR NONLINEAR DIFFUSION PROBLEMS(TAYLOR & FRANCIS INC, 2014-06-03) Simon, Laurent; Ospina, Juan; Universidad EAFIT. Departamento de Ciencias; Lógica y ComputaciónA Laplace transform-based procedure was proposed to calculate the effective time constant for a class of nonlinear diffusion problems. The governing mathematical representation was first estimated with a linear model by omitting the nonlinear term. The solution to this problem was later introduced into the original equation, which was solved with Laplace transforms, resulting in a first-order approximation of the real system's behavior. A time constant was calculated using frequency-domain expressions. Two case studies were considered to illustrate the methodology. As the rate of heat supplied to a rod is raised, the speed at which the temperature reached an equilibrium value decreased. Increasing the maximum velocity in reaction-diffusion transport by a factor of three lowered the time constant by only 1.7%. The applications of this method range from biosensor dynamics to process control. © 2014 Copyright Taylor and Francis Group, LLC.Publicación Development of an Energy Management Strategy for an electrically powered solar vesselDevelopment of an Energy Management Strategy for an electrically powered solar vessel(Universidad EAFIT, 2023) Mendoza Giraldo, Felipe; Mejía Gutiérrez, Ricardo; “ENERGETICA 2030" Research Program; The World Bank; Ministry of Science, Technology andInnovation (Minciencias)Ítem Evaluación de una red neuronal para la solución de ecuaciones diferenciales(Universidad EAFIT, 2023) Machado-Loaiza, José Manuel; Guarín-Zapata, NicolásPublicación Influence of pulse-type inputs on parameter estimation and chemical control assessment in a dengue deterministic model(Universidad EAFIT, 2019) Cataño López, Alexandra; Vélez Sánchez, Carlos Mario; Rojas Díaz, DanielÍtem Solving a Classical Optimization Problem Using GAMS Optimizer Package: Economic Dispatch Problem Implementation(Universidad EAFIT, 2017-11-07) Montoya Giraldo, Oscar Danilo, Mag.; Universidad Tecnológica de PereiraPublicación Towards a holistic framework to model epidemics in presence of uncertainty : formulation of mathematical models and estimation of confidence intervals(Universidad EAFIT, 2021) Rojas Díaz, Daniel; Vélez Sánchez, Carlos Mario; Puerta Yepes, María Eugenia; Cadavid Moreno, Carlos Alberto; Universidad EAFIT
