dust storms are known as hazardous problems in western part of iran. iraq is one of the main sources for dust storm arriving to the western part of iran. the radial basis function network model (rbfn) has been used to assess wind erosion hazards in the source area of dust storms over several western iranian cities. normalized difference salinity index (ndsi) was used to determine the changes in...

Abstract The southeastern Amazon has recently been shown to be a net carbon source, which is partly caused by drying conditions. Drying depends on number of factors, one the land cover at locations where moisture originated as evaporation. Here we assess for first time origins that precipitates in source region, using output from Lagrangian atmospheric tracking model. We relate vegetation produ...

Estimating the directions-of-arrival (DOAs) of propagating plane waves is a problem of interest in a variety of applications including radar, mobile communications, sonar, and seismology. The widely studied uniform linear array (ULA) can only provide estimates of source bearings relative to the array axis. A planar. array is required if estimates of source azimuth and elevation are required (2D...
