commercial detergents, in spite of their various names and marks, are used to remove foreign matter (dirt) from substrate. following removal of dirt from the surface, it is necessary to prevent redeposition, so the detergent must have supending power. in this experimental work, a simple method has been developed to evaluate the cleaning power of commercial detergents. the method, showing the ch...

We study the problem of change point localization in dynamic networks models. assume that we observe a sequence independent adjacency matrices same size, each corresponding to realization an unknown inhomogeneous Bernoulli model. The underlying distribution are piecewise constant, and may over subset time points, called points. concerned with recovering number positions In our model setting, al...

This study aims to analyze the groundwater flow changes caused by rainfall and its influence on slope stability. Taking in Dingjiafen, Chuxiong, Yunnan, China as area, monitored data of drew upon calculation module ArcGIS predict change water level fluctuation soil. In this way, visual simulation distribution was realized; seepage slope’s stability also analyzed. The results indicate that: (1) ...
