The use of small blocks with model-building results for overall structural model splicing can unify fault understanding, effectively integrate existing block results, and form a unified continuous model. This article focuses on the models two in central western parts certain area, studies method at sedimentary unit level to lay foundation precise tapping potential edge.

Hyperspectral images are characterized by hundreds of spectral bands and rich information. However, there exists a large amount information redundancy among adjacent bands. In this study, spatial–spectral combination method for hyperspectral band selection (SSCBS) is proposed to reduce redundancy. First, the image automatically divided into subspaces. Seven algorithms classified as four types e...

in this paper, we propose a new method for fuzzy numbers. in this method, we assume that ai= (ai1, ai2, ai3, ai4) is to be a fuzzy number. so, the convex combination of ai1 and ai2 and also the convex combination of ai3 and ai4 are obtained separately. then, mic and mis that are to be the convex combinations and the standard deviation respectively we acquire them from these components. finally,...
