Air pollution data are large-scale datasets that can be analyzed in low scales by clustering to recognize the pattern of and have simpler more comprehensible interpretations. So, this study aims cluster days year 2017 according hourly O3 PM10 amounts collected from four stations Tabriz using spatiotemporal mixture model–based (STMC). Besides, with temporal dimension (TMC) without considering di...

weather data generators (wgs) have been developed for an extension of time series of such weather variables as rainfall, temperature and relative humidity to provide better understanding of systems affected by climatic factors. different algorithms have been applied in these generators, broadly divided into parametric & non-parametric ones. in this study, the performance of non-parametric gener...

recently, the s receiver function method has been successfully developed to identify upper mantle interfaces. s receiver functions have the advantage of being free of s-wave multiple reflections and can be more suitable than p receiver function for studying mantle lithosphere. however, because of specific ray geometry of the s-to-p converted waves, the s receiver function method has some techni...

Background: Forecasting of air pollutants has become a popular topic of environmental research today. For this purpose, the artificial neural network (AAN) technique is widely used as a reliable method for forecasting air pollutants in urban areas. On the other hand, the evolutionary polynomial regression (EPR) model has recently been used as a forecasting tool in some environmental issues. In ...

Objective of this study is to determine whether there are significant changes in maximum temperature trends between the current (1981-2010) and future (2011-2099) periods. To this end, statistical downscaling is used to project future changes in the maximum temperatures according to A2 and B2 scenarios of HADCM3 in the 7 selected stations of Iran. The possibilities of an accelerating trend are ...

OBJECTIVES Quarantine measure for prevention of epidemic disease and further evaluations of their efficiency are possible only by elaborating analyses of imported cases. The purpose of this study was to analyze descriptive epidemiological characteristics of pandemic influenza A (H1N1) cases imported to Korea. METHODS We collected two sets of data. The first set, comprised daily reported cases...

Digital tuning systems are fast replacing the conventional mechanical systems in AM/FM and television receivers. The desirability of the digital approach is mainly due to the following features: Y Precise tuning of station frequencies Y Exact digital frequency display Y Keyboard entry of desired frequency Y Virtually unlimited station memory Y Up/down scanning through the band Y Station ‘‘searc...
