Monitoring lipase/esterase activity by stopped flow in a sequential injection analysis system using p-nitrophenyl butyrate
(MDPI, 2015)"Lipases and esterases are biocatalysts used at the laboratory and industrial level. To obtain the maximum yield in a bioprocess, it is important to measure key variables, such as enzymatic activity. The conventional method ... -
Attractors generated from switching unstable dissipative systems
(2012)"In this paper, we present a class of 3-D unstable dissipative systems, which are stable in two components but unstable in the other one. This class of systems is motivated by whirls, comprised of switching subsystems, ... -
Stability analysis of proportional-integral AQM controllers supporting TCP flows
(2007)"Este artículo se centra en la estabilidad asintótica de controladores AQM del tipo proporcional–integral suportando flujos TCP . Se proporcionan condiciones necesarias y suficientes para la estabilidad asintótica de la ... -
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, ... -
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. ... -
Virtual estimator for piecewise linear systems based on observability analysis
(MDPI, 2013)"This article proposes a virtual sensor for piecewise linear systems based on observability analysis that is in function of a commutation law related with the system's outpu. This virtual sensor is also known as a state ... -
Análisis de una familia de osciladores con múltiples enroscados
(2012)""En este trabajo se analizan series de tiempo con dinámica caótica provenientes de un sistema de comunicación. El análisis se realiza con la transformada ondoleta ortogonal, la cual nos proporciona información sobre la ... -
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 ... -
Magnetism of small Cr clusters: interplay between structure, magnetic order, and electron correlations
(2010)"The magnetic properties of small Cr-N clusters (N <= 6) are investigated in the framework of density-functional theory. The interplay between electron correlations, cluster structure, and magnetic order is quantified by ... -
Electronic and magnetic properties of Co and Ni impurities in Cu wires: first-principles investigation of local moment formation in one dimension
(2010)"The local moment formation in one-dimensional (1D) systems is investigated in the framework of a generalized gradient approximation to density-functional theory (DFT). The electronic and magnetic properties of Co and Ni ... -
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, ... -

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 ... -
A different three-port DC/DC converter for standalone PV system
(Hindawi, 2014)"A three-port converter suitable for standalone applications is proposed in this paper. Each port is used for specific input or output, and its functions depend on the port; they are the renewable source, the battery set, ... -
Maximum power point tracking based on sliding mode control
(Hindawi, 2015)"Solar panels, which have become a good choice, are used to generate and supply electricity in commercial and residential applications. This generated power starts with the solar cells, which have a complex relationship ... -
Stability of gain scheduling control for aircraft with highly nonlinear behavior
(Hindawi, 2014)"The main goal of this work is to study the stability properties of an aircraft with nonlinear behavior, controlled using a gain scheduled approach. An output feedback is proposed which is able to guarantee asymptotical ... -
Robust switched predictive braking control for rollover prevention in wheeled vehicles
(Hindawi, 2014)"The aim of this paper is to propose a differential braking rollover mitigation strategy for wheeled vehicles. The strategy makes use of a polytopic (piecewise linear) description of the vehicle and includes translational ...
