Evaluación del tamaño de partícula de manganitas de calcio dopadas con europio, sintetizadas por el método de combustión
(2008)
En este trabajo se estudió la síntesis de manganitas de calcio dopadas con europio, mediante el método de combustión, utilizando urea como agente reductor. Se varió la cantidad de combustible (urea) a fin de investigar la ...
ON THE SUB-OPTIMAL FEEDBACK CONTROL LAW SYNTHESIS OF UNDERACTUATED SYSTEMS
(2009)
In this paper, a complete solution on the suboptimal feedback control law synthesis for underactuated systems, based on the general optimization framework of the Dynamic Programming Theory is introduced. Control method ...

A multi-agent system to construct production orders by employing an expert system and a neural network
(2009)
The authors describe the implementation of a multi-agent system, whose goal is to enhance production planning i.e. to improve the construction of production orders. This task has been carried out traditionally by the module ...
Thermal model for a microhot plate used in a MEM gas sensor
(2008)
A thermal analytical model for a MEM gas sensor is presented and compared with an electrical circuit equivalent model. The objective is to study the temperature performance of the microhot plate configured within a MEM ...
JAPIEST: An integral intelligent system for the diagnosis and control of tomatoes diseases and pests in hydroponic greenhouses
(2008)
Automated Hydroponic Greenhouses represent novel food production systems which include modules for supervising the cultivated soil, packaging plans, as well as prevention, diagnosis and control of pests and diseases. In ...
Toward a generalized sub-optimal control method of underactuated systems
(2011)
In this paper, some experimental results and a performance analysis of a general control methodology for swinging up and stabilizing underactuated two-link robots are presented. The analyzed methodology is based on Euler ...
Propiedades sensoras de películas delgadas de SnO2 en una atmósfera de propano
(2009)
Las propiedades de sensado de las películas delgadas de oxido de estaño (SnO2) sin impurificar en una atmosfera de propano (C3H8) como función de la tempratura de depósito y del espesor de la película han sido estudiadas ...
Analysis of the potential upon the floating gate of an FGMOSFET used as a gas sensor
(2008)
Gas sensor structures using metal oxides as sensing layers are widely used, but commonly the resistance variation of these layers is used to correlate this parameter with gas concentration. Here, we show that the sensitivity ...
