graphene sheet including single vacancy, double vacancy and stone-wales with armchair and zigzag structure was simulated using molecular dynamics simulation. the effect of defects on shear’s modulus, shear strength and fracture  strain was investigated. results showed that these shear properties reduce when the degrees of all kinds of defects increase. the dangling bond in sv and dv defected gr...

to evaluate the effects of the current situation and future development on source groundwater whether quantitative or qualitative point of view, simulation computer resources, a powerful tool in the optimal utilization of source is considered. year recent several model of math and computer simulation of hydraulic behavior of underground water resources focus is located. like making mathematical...

systems perspective' should help the overcoming of artificial subject barriers such as this. The work of Blunt, Duquet and Luckie was concerned with the extent of the resources needed, and the response time, of an information retrieval service, and appears to be especially useful in determining the extent to which response time is affected by the competition by queries for resources. Hertz et a...
