Vesicle motion during sustained exocytosis in chromaffin cells: numerical model based on amperometric measurements
(2015)
"Chromaffin cells release catecholamines by exocytosis, a process that includes vesicle docking, priming and fusion. Although all these steps have been intensively studied, some aspects of their mechanisms, particularly ...
Multiscroll attractors by switching systems
(2010)
"In this paper, we present a class of three-dimensional dynamical systems having multiscrolls which we call unstable dissipative systems (UDSs). The UDSs are dissipative in one of its components but unstable in the other ...
Pattern formation by two precipitated species during solvent evaporation
(2008)
"We investigate the pattern formation produced by precipitated species during solvent evaporation through the numerical solution of a set of partial differential equations that account for the mechanisms of evaporation, ...
Applying graph theory to arterial vascular tree of the kidney
(2009)
"The renal vascular development occurs through vasculogenesis and/or angiogenesis. Particularly, there are two types of vascular angiogenesis: sprouting and splitting. We show the graphs can generate binary tree structures ...
Supresión experimental de caos mediante control nominal H∞
(2002)
"La contribución del trabajo aborda la implementación del sistema de control sintetizado vía H∞ nominal en un circuito electrónico que representa el sistema caótico del tipo Malasoma."
Convertidor elevador: mapa unidimensional y dinámica no lineal
(2005)
"En esta contribución se realiza el desarrollo de un mapa discreto en el tiempo del convertidor elevador controlado en modo corriente pico a partir de sus formas de onda. Se presentan criterios de existencia de puntos ...
Robust sliding mode‐based extremum‐seeking controller for reaction systems via uncertainty estimation approach
(John Wiley & Sons, 2017-01)
"This paper deals with the design of a robust sliding mode‐based extremum‐seeking controller aimed at the online optimization of a class of uncertain reaction systems. The design methodology is based on an input–output ...
On the dynamic behaviour of a class of bioreactor with non-conventional yield coefficient formSobre el comportamiento dinámico de un tipo de biorreactor con un coeficiente de rendimiento no convencional
(2015-04)
"The goal of this work is to analyze by numerical bifurcation the dynamical behavior of a class of continuous bioreactor used to hydrolyze cellulose using Cellulomonas cellulans, talcing into account the effect of mo deling ...
Dynamic nonlinear feedback control applied to improve butanol production by Clostridium acetobutylicum
(2017-12)
"The goal of this work is to present a closed-loop operational strategy in order to improve the butanol production in an anaerobic continuous bioreactor for the called Acetone-Butanol-Ethanol (ABE) process. The proposed ...
Nonlinear and robust control strategy based on chemotherapy to minimize the HIV concentration in blood plasma
(2016)
"A nonlinear PI-type control strategy is designed in order to minimize the HIV concentration in blood plasma, via medical drug injection, under the framework of bounded uncertain input disturbances. For control design it ...
