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...
Fractal dimension confidence interval estimation of epicentral distributions
correlation dimension confidence interval seismicity
2015/9/30
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 ...
