چکیده
aerosol impact on people health, social and economic activities, land and water ecosystems and meteorological parameter. the gocart scheme was evaluated for simulating pm10 in this study. gocart was run into wrf model as a host model. reanalysis data from fnl for every 6 hour was used for initial conditions. one domain and two nests were used to cover region from west africa till east asia, iran and khuzestan province. primary results shown that the model overestimate surface moisture and the results was weak for simulating pm10 ,so we modified surface moisture using welting point of soil texture in desert region for summer. in addition, erodibility index was defined using surface moisture and threshold wind velocity and coefficient of this index modified using tir and day pm10 data at 1387. results of modified model were compared with observed data in environmental station in ahwaz for one week from 25, 3,1388 till 31,3,1388. statistical analyses shown that, gocart has a good capability for simulating pm10.

A hybrid scheme for simulating epitaxial growth
This article continues the development of a hybrid scheme for simulating epitaxial growth that combines the Burton– Cabrera–Frank (BCF) model with kinetic Monte-Carlo (KMC) simulation. This is the first implementation of the scheme for ‘‘2+1’’ dimensional growth. Other improvements over an earlier version include the use of a more conventional KMC model and some refinement in the handling of th...

متن کاملScale-separation scheme for simulating superfluid turbulence: Kelvin-wave cascade.
A Kolmogorov-type cascade of Kelvin waves-the distortion waves on vortex lines-plays a key part in the relaxation of superfluid turbulence at low temperatures. We propose an efficient numeric scheme for simulating the Kelvin-wave cascade on a single vortex line. This idea is likely to be generalizable for a full-scale simulation of different regimes of superfluid turbulence. With the new scheme...

The remote sensing community has long been active in developing, evaluating, and comparing different classification algorithms using a variety of remotely sensed imagery. As an integral component of image classification, accuracy assessment is usually conducted to evaluate the agreement between the classified map and the corresponding reference data. However, current accuracy assessment practic...
