Proteomic analysis of non-toxic Jatropha curcas byproduct cake: fractionation and identification of the major components
(Elsevier, 2018-01)"Jatropha curcas non-toxic genotypes have been reported in Mexico and the press-cake, after oil extraction, represents a potential of new source of protein for food and feed uses. However, the characterization of the ... -
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 ... -

(2003)"Se lleva a cabo la estabilización de un reactor catalítico para la alquilación de hidrocarburos a pesar de cinética incierta mediante la robustificación de un controlador obtenido a partir de técnicas de control geométrico. ... -
Supresión de caos en una subclase CK-equivalente bajo control óptimo
(2003)"En este trabajo se presenta la supresión de caos por medio de una retroalimentación dinámica basada en control óptimo lineal para un subclase de sistemas dinámicos de tercer orden. Así, se compara un controlador clásico ... -
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 ... -
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 ... -
Insights on structure and function of a late embryogenesis abundant protein from Amaranthus cruentus: an intrinsically disordered protein involved in protection against desiccation, oxidant conditions, and osmotic stress
(Frontiers Media S.A., 2017-05)"Late embryogenesis abundant (LEA) proteins are part of a large protein family that protect other proteins from aggregation due to desiccation or osmotic stresses. Recently, the Amaranthus cruentus seed proteome was ... -
Niederhauser's model for epilepsy and wavelet methods
(2006-06)"Wavelets and wavelet transforms (WT) could be a very useful tool to analyze electroencephalogram (EEG) signals. To illustrate the WT method we make use of a simple electric circuit model introduced by Niederhauser [1], ... -
On friction effects as a mechanism to induce complex dynamical behavior in earthquakes
(2012)"In this paper we analyze a nonlinear dynamical system that describes the kinetic mechanism between tectonic plates on the crust´s earth undergoing stick slip movement. The analysis includes friction effects and an empirical ... -
Make a PI controller on an 8-bit micro
(2006-01)"This article shows you how to implement a classical PI (proportional-integral) controller on a simple 8-bit microcontroller. To implement the PI controller, we developed specific libraries that make it possible for the ... -
Self-image effects in diffraction and dispersion
(2006-06)"Talbot's self-imaging effect occurrs in near-field diffraction. In the rational paraxial approximation, the Talbot images are formed at distances z=p/q, where p and q are coprimes, and are superpositions of q equally ... -
Unveiling uncertain forces in second-order driven oscillators via internal model: a discrete-time feedback
(Hindawi, 2000-02)"Unveil uncertain forces acting into (or onto) systems is a very interesting and old problem. Indeed, a lot effort has been devoted to develop procedures which results in the understanding of the uncertain forces and its ... -
High tolerance to high-light conditions for the protected species Ariocarpus kotschoubeyanus (Cactaceae)
(2017-07)"We determined the seasonal ecophysiological performance under perennial plants and under high solar radiation for adult individuals from the "living rock" cactus Ariocarpus kotschoubeyanus, which occurs equally under nurse ... -
Mapas escalares de un convertidor elevador en modo corriente
(2003)"En esta contribución se analiza una clase de mapa escalar obtenido a partir de las formas de onda del convertidor elevador controlado en modo corriente pico sin rampa estabilizadora. Se establecen condiciones necesarias ... -
Comparing performance on chaos control via adaptive output-feedback
(2006)"Performance of four controllers is experimentally compared and evaluated in context of chaos suppression. Four output-feedback controllers are used in experi- ments for comparison. First three schemes utilize an adaptive ... -
Generation of multi-scroll attractors without equilibria via piecewise linear systems
(2017-05)"In this paper, we present a new class of dynamical system without equilibria which possesses a multiscroll attractor. It is a piecewise-linear system which is simple, stable, displays chaotic behavior and serves as a model ... -
A note on optimization of chaos suppression via robust asymptotic feedback: accounting control cost
(2000)"This paper deals with the chaos suppression for oscillators in canonical form. The underlying idea is to optimize the robust chaos supression by accounting the control cost. The robust chaos supression is attained by the ... -
