The element-free Galerkin method is a method which... uses nodal points, but where the use of a connectivity is absent. Displacements and stresses in the material domain are approximated by means of a connectivity-free technique known as moving least squares approximation. This technique requires, besides the nodal data, a set of weight functions and a set of basic functions. Since the growth of crack surfaces can be reflected without changing a connectivity of nodes, it is possible to simulate crack propagation without remeshing.  4, record 3, English, - element%2Dfree%20Galerkin%20method

The method of enhanced microwave scattering is based on the measurement of the signal, which is Back Scattered(BS) in the Upper Hybrid Resonance(UHR) vicinity. At first this technique was applied to small-scale oscillations and waves investigations in quiet plasma of linear laboratory devices. But now this method is introduced for a study of plasma small-scale turbulence and wave propagation in the tokamak plasma.  2, record 4, English, - upper%20hybrid%20resonance
