In this paper we define gradation of RS-compactness and S*-closed spaces in L-topological spaces.We generalize the degrizations of RS-compactness and S*-closedness to the L-topological space and give the positions of them under weak forms of L-continuity. 2010 AMS Classification: 54A40, 06D72

The new strategy for non-uniform initial FE mesh generation is presented in this paper. The main focus is set to a priori procedures that define the sizing function independent on the mesh generation algorithm. The sizing function used by the mesh generation algorithm is established by control sphere and control space concepts and fully controls mesh gradation in the complex 2D problem domains.

A constant head permeability test of the coarse-grained soil an earth-rockfill dam was carried out and gradation tested determined based on continuous equation. Based results, empirical formula coefficient considering influence established. The can be used to assess with respect area under curve. applicability verified results from other studies. It found that suitable for soil. This paper prov...

construction of porous barriers to collect flood flows and gradual release of water, later, is one of the effective techniques for flood control. in this study, by carrying out a set of experiments in a flume with the width of 0.6, depth of 0.8, and length of 14 m, the effects of gradation of stones and downstream slope on the stability of such structures has been investigated. moreover, the in...

In this paper we present a theoretical analysis to understand sparse filtering, a recent and effective algorithm for unsupervised learning. The aim of this research is not to show whether or how well sparse filtering works, but to understand why and when sparse filtering does work. We provide a thorough theoretical analysis of sparse filtering and its properties, and further offer an experiment...
