... between actual value and their values is less than 15%. Apparent density is dependent on scale, but the Mauldon's estimators are independent of scale despite the variation in fracture length. For all joint sets, the difference of apparent areal intensity by samplings windows and circular estimator is less...

... treatment of the crack orientation data presented by a stereographic projection together with the detailed data of fracture size and aperture. It is possible to estimate the crack tensor components using mathematical expectation of crack parameters treated as random variables. 1. Introduction...

... estimation by Palmström (1996) and the P 32 estimation by Dershowitz (1985). The first one considers the total number of discontinuities in a certain volume weighed by the joint persistence whilst the second method consider the joint area computed by a statistical analysis of the traces under the hypothesis...
