Real-time data of PM2.5 and PM10 concentrations in summer of 2013 released from Taiyuan Environmental Monitoring Center were collected. The regular pattern of their distribution and temporal (monthly, daily and hourly) variations were analyzed. The results showed that daily concentrations of PM10 ranged between 32 - 276 μg/m3 and those of PM2.5 ranged between 17 - 136 μg/m3. Similar diurnal variations of PM2.5 and PM10 concentrations with single-valley pattern were observed. Daily maximum concentrations of both PM2.5 and PM10 appeared in June. PM2.5/PM10 ratios varied between 0.46 - 0.55, and significant linear correlation (correlation coefficient of 0.81) between PM2.5 and PM10 was found.

    Measures of divergence or discrepancy are used either to measure mutual information concerning two variables or to construct model selection criteria. In this paper we focus on divergence measures that are based on a class of measures known as Csiszár's divergence measures. In particular, we...

    Data processing requires a robust linear fit identification method. In this paper, we introduce a non-parametric robust linear fit identification method for time series. The method uses an indicator 2/n to identify linear fit, where n is number of terms in a series. The ratio Rmax of amax...

    Abstract. In this paper, a linear model selection procedure based on M-estimation is proposed, which includes many classical model selection criteria as its special cases. It is shown that the proposed criterion is strongly consistent under certain mild conditions, for instance without assuming...

    The integrated system of geosystem assessment and disturbed geosystem recovery is suggested. It includes expert conclusions, geo-environmental monitoring results and generalization of the multivariate data in the form of criterion groups. The integral indicator of disturbed Geosystem stability...

    This paper presents a review about the theory of regression analysis based on Jørgensen's dispersion models, which extends the classical theory of generalized linear models (GLMs). Dispersion models provide a rich class of parametric models useful to conduct regression analysis of non-normal...

    The calculation of the distribution of a linear combination of order statistics from random variables that are uniformly distributed is considered. A simple recursion to compute this distribution is presented that, unlike previous methods, is numerically stable and efficient. As such, this...

    Let A = An(E, τ) be the n-dimensional Sklyanin algebra associated with a smooth elliptic curve E and point τ ∈ E. This paper classifies linear modules over A. We show that d-linear modules are in bijection with those d-planes in P(A1*) which are either secant to E or are singular...
