The expeditious expansion in the use of inexhaustible recurrent energy resources like Wind turbines and PV cells, in the distribution network has evaluated the need for having rigorous and adequate method of dealing uncertainties correlated with these technologies. In this project the unsymmetrical two point estimate method (US2PEM) is used to approach uncertainties of renewable energy resource...

A large number of multiscale finite-volume methods have been developed over the past decade to compute conservative approximations to multiphase flow problems in heterogeneous porous media. In particular, several iterative and algebraic multiscale frameworks that seek to reduce the fine-scale residual towards machine precision have been presented. Common for all such methods is that they rely o...

A brief background to the development of the rock engineering design process is given, showing that since the development of the science of mathematics, deterministic methods have been used to perform various calculations. The variability of rock properties and support characteristics have always been known. However, they were not explicitly used in design but compensated for by the use of a sa...
