How large a sample is needed to estimate the regional variogram adequately? few data, but because confidence limits cannot be determined analytically from a single set of data its precision is unknown. Approximate confidence intervals can be found numerically by Monte Carlo simulation. A large field of values is created using a plausible model of the variogram. It is thenCongregate 发表于 2025-3-24 00:32:57
Depth, Dip and Gradientint . using the depths . and the gradients (∇.). known at the experimental points. This procedure is rather demanding insofar as it involves a gradient which implies that the depth formation is twice differentiable. In addition it may not be the most realistic one. The gradient (i.e. a point measure弄皱 发表于 2025-3-24 04:00:19

Conditioning a Gaussian model with inequalitiesssian random functions. In these cases, the conditions at experimental points are expressed in terms of inequalities: 1 ≤ . ≤ ., .. ≤ .. ≤ ... The simulation with composite constraints (equalities and inequalities) is performed in two steps: firstly we ensure that the inequality constraints are valiexercise 发表于 2025-3-24 12:27:47

Random Functions and Fracture Statistics Modelst fracture criteria are introduced: the weakest link assumption and a critical damage model. They involve two different kinds of change of support, namely by a convolution and by an inf. operation..Examples of random function models are presented, for which a theoretical calculation of coherent frac捏造 发表于 2025-3-24 20:47:24
