    Lot production size problem and simulation of urban transport por Morales Marroquín, Miguel Lorenzo

    Publicado 2015
    “…Molds must be mounted on machines with their corresponding installation setup times. The key point of our methodology is to solve the single period lot-sizing decisions for the finished products together with the piece-mold and the mold-machine assignments, relaxing the constraint that a single mold may not be used in two machines at the same time. …”

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

    Publicado 2016
    “…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. …”

    Diferencias de género en las actitudes hacia las matemáticas = Gender differences in attitudes toward mathematics por De la Torre Gamboa, Martha Patricia, Ramírez Martínez, Martín

    Publicado 2018
    “…Abstract The results of previous research do not allow us to generalize the existence of gender differences in attitudes toward mathematics, however they coincide in the majority in pointing out that men have a greater extrinsic motivation, that they show greater confidence in their future achievements in the area of mathematics, less anxiety about mathematics and attribution of success to external causes. …”
