In this paper, some meshless methods based on the local Newton basis functions are used to solve some time dependent partial differential equations. For stability reasons, used variably scaled radial kernels for constructing Newton basis functions. In continuation, with considering presented basis functions as trial functions, approximated solution functions in the event of spatial variable wit...

Artificial recharge can be an effective method to raise the groundwater table and to resolve the groundwater crisis in Sefid dasht plain. The most important step to successful accomplishment of artificial recharge is locating suitable areas for artificial recharge. Hence this research carried out with purpose of determining suitable areas for artificial recharge in Sefid dasht plain. Slope, sur...

Two simple algorithms to generate gamma random numbers are proposed in this article. Both algorithms use the ratio-of-uniforms method and are based on logarithmic transformations of the gamma random variable. One algorithm applies to all positive shape parameter value without limitation. It has good performance compared with other existing algorithms for both shape parameter values greater than...
