    Hypothesis test for changes in variance using a statistic based in P-values in a time series of normal independent observations. por Armendáriz Hernández, Samuel Uriel

    Publicado 2015
    “…A regression approach was used to simplify the quantile evaluation and extrapolation. The power of the test was simulated using Monte Carlo simulation, and the results were compared with the Chen test (1997) to prove its efficiency. …”

    Effect of the Microstructures Formed in Cements Modified by Limestone Agave Bagasse Ash, Fly Ash, Geothermal Nano-SiO2 Waste and Silica Fume on Chloride Ion Penetration Resistance por Puente Ornelas, Rodrigo, Chávez Guerrero, Leonardo, Fajardo San Miguel, Gerardo, Rodríguez, E. A., Trujillo Álvarez, Alejandro, Rivas Lozano, Hugo E., Delgadillo Guerra, Herlinda María

    Publicado 2016
    “…The chlorine ion penetration ratio had also low values giving an ion penetration resistance around 57 % less. These results revealed that geothermal nano-SiO2 waste (GNW) and limestone of agave bagasse ash (ABA) could be considered as a potentially suitable material for making pastes, mortars and concrete for industrial applications, which will contribute positively to the reduction of the CO2 emissions into the atmosphere, as well as decrease the environmental impact generated at the disposal zones.…”
