Control no lineal por modos deslizantes de una columna de destilación binaria por Acosta Solano, Rubén Omar

“…Se implementó un controlador Proporcional-Integral (PI), un control basado en la técnica de linealización por retroalimentación (FLC) y el control continuo por modos deslizantes (CSMC), se encontró que este ´ultimo presenta una convergencia más rápida hacia el set-point y un menor sobre tiro.…”

Análisis geomecánico utilizando el método RMR, de un macizo rocoso ubicado en el km 40 de la carretera Linares – Iturbide. por Garza Pérez, Magdaleny

“…The RMR (ROCK MASS RATING) method proposed by Bieniawski in the 80's will be used as a parameter to classify the quality of the rock mass from a geological engineer point of view, so with complementary data to establish the parameters of the rocky mass for the purpose of slope stability, determining the degree of risk and generating necessary measures to deal with possible damages that could be generated. …”

Thermomechanical Performance of fr-4 Laminates in the Manufacturing Process of Printed Circuit Boards. por Rodríguez Vázquez, Carlos Alfonso

“…In 2006 the Restriction of Hazardous Substances (RoHS) prohibited the use of lead (Pb) in solder paste, which has a melting temperature around 180oC, whereas lead-free solder pastes have a melting point around 230oC, 30oC-40oC higher than Pb solder paste, this has generated PCB thermo mechanical problems due to the temperature increase at which the material is exposed. …”

Artificial neural network modeling of phenol adsorption onto barley husks activated carbon in an airlift reactor por Loredo Cancino, Margarita

“…Purpose and method of the study: The production of activated carbon from barley husks (BH) by chemical activation with zinc chloride was optimized by using a 23 factorial design with replicates at the central point, followed by a central composite design with two responses (the yield and iodine number) and three factors (the activation temperature, activation time, and impregnation ratio). …”
