In this talk, we investigate the fractalization phenomena for the multi-component systems of the dispersive evolution equations on a bounded interval subject to the periodic boundary conditions. The e...
日前,2018级博士研究生夏宇轩在国际学术期刊《分形》发表题为《一种基于多孔介质孔径分布的分形维数新计算方法》的论文,入选Mathematics学科领域高被引论文。在该论文中,夏宇轩提出了一种基于分形毛细管假设的计算多孔介质孔隙空间和迂曲度分形维数的新方法。
近日,中国地质大学地空学院蔡建超教授团队在国际著名地学期刊Journal of Hydrology上发表了储层岩石复杂微观结构定量表征及渗透率建模领域的研究成果:“Fractal dimension, lacunarity and succolarity analyses on CT images of reservoir rocks for permeability prediction”。该文...
近日,国际地球物理Nature Index期刊《Journal of Geophysical Research: Solid Earth》刊出了中国地质大学关于多孔介质二维和三维之间输运机理方面的最新研究成果:基于分形几何的二维截面分析确定毛细管压力曲线:多孔介质的二维和三维孔隙结构之间的桥梁(Capillary Pressure Curve Determination Based on a 2-...
近日,国际传热传质领域顶级期刊《International Journal of Heat and Mass Transfer》在线刊发了中国地质大学地空学院蔡建超教授团队的最新研究成果---A fractal model of effective thermal conductivity for porous media with various liquid saturation。论文第一作者...
近日,能源领域的重要国际期刊《Fuel》在线刊发了中国地质大学地空学院蔡建超教授团队的研究成果- Kozeny-Carman constant of porous media: Insights from fractal-capillary imbibition theory。论文第一作者为地空学院2015级博士研究生韦伟,通讯作者为地空学院蔡建超教授。
It is a complicated process to analyze the cause of geological hazard. Through the analysis function of GIS software, 250 landslides were randomly selected from 395 landslide hazards in the study area...
The paper presents a novel hydraulic fracturing model for the characterization and simulation of the complex fracture network in shale gas reservoirs. We go beyond the existing method that uses planar...
Estimates of the fractal dimension of hypocentral distributions require evaluating the range of independent variables in which fractal parameters exhibit a power law. Systematic and accidental errors ...
The Grundy number of an impartial game G is the size of the unique Nim heap equal to G. We introduce a new variant of Nim,Restricted Nim, which restricts the number of stones a player may remove from ...
The radioisotope pollution shows two types of patterns: dry and wet deposits for nuclear power plant accidents. Two surface pollution patterns were analysed by fractal. In Fukushima nuclear power pl...
We present a new approach to the theory of k-forms on self-similar fractals. We work out the details for two examples, the standard Sierpinski gasket and the 3-dimensional Sierpinski gasket, but the m...
A gray-level image texture descriptors based on fractal dimension estimation is proposed in this work. The proposed method estimates the fractal dimension using probability (Voss) method. The descript...
Experiments have revealed that the Fresnel drag effect is not present in RF coaxial cables, contrary to a previous report. This enables a very sensitive, robust and compact detector, that is 1st order...
We consider the optimal covering of fractal sets in a two-dimensional space using ellipses which become increasingly anisotropic as their size is reduced. If the semi-minor axis is \epsilon and the se...
