Paper Title :: Fractional Taylor Series Based on Jumarie Type of Modified Riemann-Liouville Derivatives
Author Name :: Chii-Huei Yu
Country :: China
Page Number :: 01-06
In this paper, based on the Jumarie type of modified Riemann-Liouville (R-L) fractional derivatives, we use a new multiplication, fractional Taylor series method and chain rule for fractional derivatives to find the fractional Taylor series expansions of some fractional functions.These results we obtained are the generalizations of Taylor series expansions of several classical functions.
Key Words: Jumarie type of R-L derivatives,new multiplication,fractional Taylor series, chain rule

Paper Title :: Analysis of Sulfur Dioxide Concentrations in México City, trend 2010 - 2020
Author Name :: M. Sc. Zenteno Jiménez José Roberto
Country :: Mexico
Page Number :: 07-15
The study comprises an analysis of data from 2010 to 2020, it was proposed to obtain the best or best probability distribution functions that model SO2 concentrations in México City, using the following pdf, T location scale distribution function, extreme value distribution function and exponential distribution function, to obtain the estimators the method of maximum likelihood and moments was used and aided by the Matlab program, for valuation of the forecast model, RMSE, MSE, coefficient of determination, approximation of prediction and approximation index, in turn an analysis is made to observe its trend with an analysis of variance, the daily concentration data is downloaded from the official monitoring page and corroborating with the official air page of México City.
Key Words: Sulfur Dioxide, Probability Distributions, Adjustment Indicators, Analysis of Variance.
