in this research, temporal and spatial behavior of siberian high (sh) was studied at the level of 1000 h.pa. this study has been done using daily data of geo potential height at 12 gmt in ncep/ncar database with spatial resolution of 2.5ã—2.5 degree in a 55 years period including 20089 days from january, 1st, 1951(dey, 11th, 1329) to december, 31st,2005(dey, 10th,1384). at first, the mean geo p...

abstractprecipitation could be regarded as a complex and a very vital element in the earth atmosphere and its spatial-temporal changes can control iran's climate. in the current research, in order to model the spatial-temporal changes of annual precipitation, the data taking from 50 synoptic stations, have been analyzed during the years 1966-2005, with a suitable distribution. the most dat...

Video data from experiments on the dynamics of two-dimensional flames are analyzed. The Karhunen-Lo6ve (KL) analysis is used to identify the dominant spatial structures and their temporal evolution for several dynamical regimes of the flames. A data analysis procedure to extract and process the boundaries of flame cells is described. It is shown how certain spatial structures are associated wit...

Music psychologists have established that some forms of musical activity improve intellectual performance, spatial–temporal reasoning and other skills advantageous for learning. In this research, the potential of active music-making for improving pupils’ achievement in spatial– temporal reasoning was investigated. As spatial–temporal skills are considered to be high-level mathematical abilities...

Due to technical limitations, it is impossible to have high resolution in both spatial and temporal dimensions for current NDVI datasets. Therefore, several methods are developed to produce high resolution (spatial and temporal) NDVI time-series datasets, which face some limitations including high computation loads and unreasonable assumptions. In this study, an unmixing-based method, NDVI Line...
