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 ...
Glucose regulation in type 1 diabetic patients by a multi-doses regimen
(2005)
"In this paper several multi-doses control regimens are suggested for type 1 diabetic patients. The suggested regimes are proposed based on different insulin formulations. The insulin doses are assumed to be infused by a ...
Fixed reference frame phase-locked loop (FRF-PLL) for unbalanced line voltage conditions
(2008-10)
"The present invention relates to a system to implement a phase-locked loop (PLL) which is able to provide an estimation of the angular frequency, and both the positive and negative sequences of the fundamental component ...
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). ...
Una aproximación algebraica de observabilidad para un sistema de diabetes mínimo
(2008)
"La observabilidad de estados mediante la disponibilidad de un conjunto de entradas y salidas es un tema que, en concepto, es relativamente simple y como es sabido, para sistemas lineales está satisfactoriamente estudiado. ...
A dynamic parameter estimator to control chaos with distinct feedback schemes
(2009)
"A dynamic strategy is proposed to estimate parameters of chaotic systems. The dynamic estimator of parameters can be used with diverse control functions; for example, those based on: (i) Lie algebra, (ii) backstepping, ...
On the transitions between dynamical behaviors for small-world and scale-free networks
(2008)
"The effect of network topology on the transition between dynamical behaviors is investigated for two networks: the small-world and scale-free models. In our analysis, we consider a network of identical dynamical systems ...
Oportunidades para modelar y controlar enfermedades que afecta al ganado bovino en México
(2008)
"El ganado bovino en México padece de enfermedades infecciosas tales como la tuberculosis o brucelosis. Estas enfermedades disminuyen la población bovina y la producción de leche hasta en un 30% provocando pérdidas millonarias ...
Stabilization of a class of biomedical systems via stability preservation
(2008)
"We present a method for stabilization of a class of nonlinear systems. The notion of stability preservation is exploited to prove that a transformation allows to find a stabilizer. The nonlinear systems have uncontrollable ...
An analytical study of the logarithmic mean temperature differenceEstudio analítico de la media logarítmica de diferencia de temperaturas
(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 ...
