Spectral analysis of the time series for average annual values globally averaged surface temperature anomaly shows presence harmonics lunar nodal cycle with a period 18.6 years,whichcan be used to predict theseries. Three models theseries were considered: autoregression AR(p), combined model – integrated moving ARIMA(p,d,q) and artificial neural network. It is shown that ARIMA(4,1,4) gives best...

This paper reports a study to interpret the surface temperature based on time series and fuzzy measures. We demonstrated method identify uncertainty around data concerning summer monsoon in India. The random variables were standardized, Dempster-Shafer Theory was used generate common goals. Two criteria, represented as numbers, for this purpose. constructed three polynomials illustrate function...

background road traffic accidents and their related deaths have become a major concern, particularly in developing countries. iran has adopted a series of policies and interventions to control the high number of accidents occurring over the past few years. in this study we used a time series model to understand the trend of accidents, and ascertain the viability of applying arima models on data...

sulfur dioxide has two important sources in the atmosphere and this is why most of scientists believe in a geographic split in the globe. power plants, major emitter of so2, are located in north hemisphere such as in russia, china, canada and the usa. in south hemisphere, phytoplankton produces a massive amount of dimethyl sulfide (dms) and dimethyl disulfide (dmds). then these types of reduced...
