Research on flame retardant effects of different inert gases based on adiabatic oxidation experiment

open access: yesMeikuang Anquan, 2021
To grasp the difference of different inert gas flame retardancy in different oxidation stages of coal, in this paper, an adiabatic oxidation device is used, and non-adsorbable helium is used as the reference gas to design inert (N2、CO2) flame retardant ...

Polluants Time-Series Prediction Using the Gamma Classifier [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2011
In this work we predict time series of air pollution data taken in Mexico City and the Valley of Mexico, by using the Gamma Classifier which is a novel intelligent associative mathematical model, coupled with an emergent coding technique.

Influence of carbon dioxide content in the biogas to nitrogen oxides emissions [PDF]

open access: yesHemijska Industrija, 2010
Fuels derived from biomass are an alternative solution for the fossil fuel shortage. Usually this kind of fuels is called low calorific value fuels, due to the large proportion of inert components in their composition.
