Analysis and Reuse of the Fine Waste of a Residual Solid Treatment Plant of a Concrete Company to Prepare a Mortar with Hydraulic Cement

Autor: J Lozano-Navarro, T Sánchez-Medrano Ma., J R Hernandez-García, Y Aranda-Jiménez

Publikováno v: Civil Engineering and Architecture. 9:1938-1954

The purpose of the investigation is the use of a residual material through its recovery in a concrete mixer located in the town of Ixtaczoquitlan, Ver., Mexico, to make a recycled hydraulic mortar of f´c 70 kg/cm2 for masonry works, providing sustai

Proceso de descarga de un silo como una línea continua de ruido

Autor: V. Barroso, A. Lopez-Villa, A. Medina, J. R. Hernandez Juarez

Publikováno v: Suplemento de la Revista Mexicana de Física. 1:34-37

Durante el proceso de descarga de un material granular desde un silo, pueden surgir fenómenos de resonancia como la emisión de ondas acústicas. Esta contribución acústica es debida a la fricción entre los granos y la pared del silo acoplada con

Clustering approach applied on an artificial neural network model to predict PM10 in mega cities of Mexico

Autor: Arturo Valdés-Manzanilla, Sergio Ramos-Herrera, J. R. Hernandez-Barajas, Elizabeth Magaña-Villegas, José R. Laines-Canepa, Carlos González-Figueredo, R. G. Bautista-Margulis, Jesús M. Carrera-Velueta

Publikováno v: International Journal of Sustainable Development and Planning. 11:566-577

A cluster-based artificial neural network model called CLASO (Classification-Assemblage-Association) has been proposed to predict the maximum of the 24-h moving average of PM10 concentration on the next day in the three largest metropolitan areas of

A comprehensive estimation of kinetic parameters in lumped catalytic cracking reaction models

Autor: Ma.G. Félix-Flores, J. R. Hernandez-Barajas, Richart Vázquez-Román

Publikováno v: Fuel. 88:169-178

This work presents a comprehensive approach to estimate kinetic parameters when the involved reactions contain lumped chemical species. This approach is based on representing rate constants with a continuous probability distribution function. In part

Multiplicity of steady states in FCC units: effect of operating conditions

Autor: Richart Vázquez-Román, Daniel Salazar-Sotelo, J. R. Hernandez-Barajas

Publikováno v: Fuel. 85:849-859

The FCC dynamics has been studied to determine the effect of operating conditions on multiplicity of steady states. The proposed model is capable to analyze several dynamic features to characterize the FCC process. Three combustion modes are analyzed
