Mathematical formulations and optimization algorithms for solving rich vehicle routing problems. por Palomo Martínez, Pamela Jocelyn

“…The problem is modeled as a multi-product split delivery capacitated team orienteering problem with incomplete services, and soft time windows. The problem is modeled through a mixed integer linear programming formulation and approximated by means of a multi-start Adaptive Large Neighborhood Search (ALNS) metaheuristic. …”

Evaluación de la calidad del agua de tres ríos de la subcuenca del “Río Limón” en el estado de Nuevo León por Ríos Saucedo, Julio César

“…However none chamical constituent exceeded set standards but concentrations of several constituents (pH, CE, Ca2+, Mg2+ Na1 + CO3 - HCO3 Cl- , SO42-) varied according to time, river and location. The time source of variation was explained by increased discharge which appeared to control the concentration of several chemical constituents by dilution. …”

Reliability of X7R Multilayer Ceramic Capacitors During High Accelerated Life Testing (HALT) por Hernández López, Ana María, Aguilar Garib, Juan Antonio, Guillemet Fritsch, Sophie, Nava Quintero, Román Jabir, Dufour, Pascal, Tenailleau, Christophe, Durand, Bernard, Valdez Nava, Zarel

“…Abstract: Multilayer ceramic capacitors (MLCC) are essential components for determining the reliability of electronic components in terms of time to failure. It is known that the reliability of MLCCs depends on their composition, processing, and operating conditions. …”

Comparative Method Between Eddy Current and Optical Microscopy in the Determination of Thickness of 6063 Aluminum Alloy Anodization por Cabral Miramontes, José Ángel, Gaona Tiburcio, Citlalli, Lara Banda, María del Refugio, Almeraya Calderón, Facundo

“…This study compares the Eddy current technique and optical microscopy for measuring the anodized layer thickness in a 6063 aluminum alloy with the aim of establishing an efficient and accurate methodology capable of delivering optimal results in a time-efficient manner. Optical microscopy was used as the reference method, with five measurements taken in different fields for each specimen. …”
