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.Ítem 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 PereiraÍtem 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
