Bearing fault diagnosis in spindles using vibration and acoustic emission
In modern automated manufacturing processes, machinery has become more flexible and automatic but also more susceptible to conditions in different parts like spindles. The main conditions affecting them are focused in the ...
Disminución de consumo de diesél en generadores eléctricos para equipo de telefonía celular, aplicando un sistema de energía solar
El uso eficiente de los combustibles ha sido un reto durante años, esto ha llevado a diferentes organizaciones a tomar medidas y estudiar las posibilidades para disminuir su uso o incluso intentar prescindir de ellos al ...
Métodos heurísticos para el problema de asignación de trabajadores y balanceo de líneas de ensamblaje
Some types of distribution in assembly lines of manufacturing process begin as an assembly balancing problem of a certain type. In this work we propose two different algorithms based on two different methods to find a ...
Relationship between physical and acoustical parameters for road surface characterization
An acoustic system for automated road surface conditions detection from acoustic signals of surface interaction is introduced. The aim of this work is to obtain different characteristics of the roadway surface by which the ...

Modifications on physical, chemical, functional and nutraceutical properties in soft blue maize (Zea mays L.) after parboiling treatment and its impact on resistance to Prostephanus truncatus
Mexico is the center of origin and diversification of maize (Zea mays L.). However, in this country, efforts have been focused on obtaining white corn over other varieties, such as pigmented ones. Although, pigmented ...
Time-frequency method for bearing fault diagnosis
Spindle bearings are some of the most critical and vulnerable components in rotating machines. Friction, load forces and vibrations actuating over bearings can produce wear, fatigue and impending cracks on these which may ...
