Regulador de voltaje basado en un convertidor SEPIC con una celda de inductores conmutados
(2018-07)"Los convertidores de corriente directa a corriente directa han sido típicamente usados para elevar o disminuir el voltaje; sin embargo, en algunas aplicaciones existe la necesidad de mantener un voltaje regulado a partir ... -
Self-tuning insulin adjustment algorithm for type 1 diabetic patients based on multi-doses regime
(Hindawi, 2005)"A self-tuning algorithm is presented for on-line insulin dosage adjustment in type 1 diabetic patients (chronic stage). The algorithm suggested does not need information of the patient insulin–glucose dynamics (model-free). ... -
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 ... -
Estudio de mapeos caóticos discretos y su aplicación en criptografía
(2015-01)"La seguridad de la información digital cada vez tiene más auge, debido al creciente uso de dispositivos móviles, además del incremento de operaciones realizadas a través de internet. Esto representa un gran reto ya que ... -
An analytical study of the logarithmic mean temperature difference
(2005)"La media logarítmica de diferencia de temperaturas (LMTD, por sus siglas en inglés) ha causado inconveniencias en diversas aplicaciones tales como ciertos programas de simulación de procesos. Su forma indeterminada es una ... -
On Brusselator and Oregonator as chemical reaction networks: a graph approach
(2009)"This paper shows graph similarities between Brusselator and Oregonator reaction mechanisms, using the jacobian matrix in convex coordinates as an adjacency matrix which defines a weighted directed pseudograph. A linear ... -
Synchronization of chaotic systems with different order
(2002-03)"The chaotic synchronization of third-order systems and second-order driven oscillator is studied in this paper. Such a problem is related to synchronization of strictly different chaotic systems. We show that dynamical ... -
An upper limit for slow-earthquake zones: self-oscillatory behavior through the Hopf bifurcation mechanism from a spring-block model under lubricated surfaces
(2017)"The complex oscillatory behavior of a spring-block model is analyzed via the Hopf bifurcation mechanism. The mathematical spring-block model includes Dieterich Ruina's friction law and Stribeck's effect. The existence of ... -
Estructura-evolución de un modelo de sistema dinámico de terremotos: análisis de correlaciones ocultas de largo alcance
(2015)"Este trabajo se apoya en el análisis-comparación de las series de tiempo generadas por un modelo dinámico de terremotos el cual se presenta como un sistema no lineal de tercer orden que acopla leyes de fricción y ... -
Lie algebra on synchronization of different systems: a generalized function for Hodgkin-Huxley neurons
(2007)"In this contribution two results are taken: (1) The synchronization of noiseless Hodgkin- Huxley (HH) neurons is possible from robust feedback based on Lie algebra approaches and (2) the fact that, from Lie algebra of ... -
Sincronización generalizada entre sistemas Rössler y Lorenz con dinámica Interna
(2010)"Se investiga la sincronización generalizada (SG) entre los osciladores caóticos Rössler y Lorenz en una configuración maestro-esclavo. Para lograr la sincronización se diseña un controlador escalar por retroalimentación ... -
Grahp and automata in arterial vascular tree of the kidney
(2010-05)"The renal vascular development is not known and occurs through two mechanisms that sometimes overlap: vasculogenesis and angiogenesis. Here we only consider growth through angiogenesis, i.e., the arterial vascular tree ... -
A Lie-based approach to the general framework of chaotic synchronization
(2003)"Diverese phenomena have been reported on the synchornization of chaotic systems. Therefore, the generalized framework of the chaotic synchronization is an actual scienti¯c debate. Here, a Lie-based geometrical approach ... -
Modification of Mikhailov stability criterion for fractional commensurate order systems
(2018-03)"In this paper we present the modification of the Mikhailov stability criterion for linear fractional commensurate order systems. The modification consists in determining the appropriate measure for the total argument ... -
A standard microcontroller based Discrete-Time PI for controlling the motion of a DC-Gearmotor
(2005-05)"This paper shows how the INTEL© D8751 H microcontroller can be used to control the motion of a DC-Gearmotor. One advantage of this design is that does not require external memory RAM/EPROM to perform the control of the ... -

Conditions for synchronization and chaos in networks of β-cells
(2009)"The insulin producing and releasing pancreatic β-cells play a key role in glucose homeostasis. The proper function of these cells is characterized by a spiking-bursting activity in their membrane potential. It is known ... -
Feedback induction of limit cycle in a bioreactor: controlling towards scale-down
(2004)"The feedback stabilization of periodic orbits (induction of limit cycle) via PI-like control is proposed as plausible tool for scale-down studies. An isothermal continuous stirred tank bioreactor (CSTB), with nonideal ... -
