In this study, a multi-grid sampling multi-scale (MGSMS) method is proposed by coupling with finite element (FEM), extended (XFEM) and molecular dynamics (MD) methods. Crack studied comprehensively from microscopic initiations to macroscopic propagation MGSMS method. order establish the relationship between model, FEM used transmit displacement boundary conditions atomic model XFEM feedback cra...

| In this paper, we present new statistical sampling techniques for performing power estimation at the circuit level. These techniques rst transform the power estimation problem to a survey sampling problem, then apply stratiied random sampling to improve the eeciency of sampling. The stratiication is based on a low-cost predic-tor, such as zero delay power estimates. We also propose a two-stag...

• The local imbalance is more crucial than the global one in multi-label data. based measure assesses hardness of MLSOL and MLUL tackle class issue via imbalance. Suitable application situations our two methods are identified, respectively. Class an inherent characteristic data that hinders most learning methods. One efficient flexible strategy to deal with this problem employ sampling techniqu...
