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. …”

A Study of the Corrosion Behavior of AHSS Complex-Phase CP 780 Employing an Electrochemical Noise Technique Analyzed by Different Methods por Lara Banda, María del Refugio, Almeraya Calderón, Facundo, Jáquez Muñoz, Jesús Manuel, Nieves Mendoza, Demetrio, Baltazar Zamora, Miguel Ángel, Olguín Coca, Javier, Estupiñan López, Francisco H., Cabral Miramontes, José Ángel, Santiago Hurtado, Griselda, Gaona Tiburcio, Citlalli

“…AHSSs are coated by conversion methods such as phosphate to increase epoxy coating adherence and corrosion resistance. The main point of this research is to characterize an AHSS complex-phase (CP) 780 in blank, with a phosphate coating and an E-coat organic coating using electrochemical noise, employing time-domain, frequency-domain, time–frequency-domain, and chaotic system methods to determine the type and corrosion kinetics of each system. …”

Expectativas de los estudiantes de primer ingreso en la Maestria en Contaduría: Caso FACPYA (Expectations of first year students in the master of accounting: Case FACPYA) por Hernández Campos, Alfonso, Tamez Garza, Silverio, Leal Martínez, José Luis, Garza Coronado, Jessica Lizzet

“…The results indicate, among other things, that the two main areas of interest for future work to students are the Finance and Taxation, and that their interest is directed to work in the private sector in a corporate or large firm, practically leaving out the public sector. Experton points out that the learning process is easier to students through laboratory practical situations followed by lectures given by the professor, and videos of case studies. …”

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. …”

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

“…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. …”
