Memoria: Seminario regional sobre el mejoramiento de la calidad del café
(Instituto Interamericano de Cooperación para la Agricultura (IICA), 1994-11)
El documento destaca conceptos de calidad en café, desde la producción y cosecha. El control de calidad comienza en el campo, utilizando suelos y climas apropiados, nutrientes, control de plagas, uso de variedades con alto ...

On the control of the F-region drift velocity by the E-region electric field: experimental evidence
(Elsevier, 1969)
Experimental evidence is presented which shows a good correlation between velocity variations of 1. (1) the vertical motions of the F-region electrons in the equatorial ionosphere, and 2. (2) the horizontal motions of ...
Switching controllers based on neural networks estimates of stability regions and controller performance
(Springer, 1998)
This paper presents new results on switching control using neural networks. Given a set of candidate controllers, a pair of neural networks is trained to identify the stability region and estimate the closed-loop performance ...
An example of epsilon- Insensitizing controls for the heat equation with no intersecting observation and control regions.
(2004)
This article is devoted to the ɛ-insensitizing controllability of the heat equation with disjoint control and observation regions. In the 1-D case and for symmetric regions a positive answer is obtained.
