‎In this paper we establish a new numerical method for solving a class of stochastic partial differential equations (SPDEs) based on B-splines wavelets‎. ‎The method combines implicit collocation with the multi-scale method‎. Using the multi-scale method‎, ‎SPDEs can be solved on a given subdomain with more accuracy and lower computational cost than the rest of the domain‎. ‎The stability and c...

microspore culture was applied to induce embryogenesis in roses (rosa hybrida) cv. hav1. important factors affecting viability of isolated microspores and formation of multi-cellular structures including isolation media (nln, ab, b) and induction media were studied. the most responsive developmental stage of microspores (late unicellular) was determined using dapi staining. the least infection ...

In this article, a multi objective model is presented to select and allocate the order to suppliers in uncertainty condition and in a multi source, multi customer and multiproduct case in a multi period state at two levels of supply chain. Objective functions considered in this study as the measures to evaluate suppliers are cost including purchase, transportation and ordering costs, timely del...
