This paper describes methods for second-order stereology of spatial fibre systems. For stationary and isotropic fibre processes it gives practicable estimators of the K-function and the pair correlation function, which are based on planar sections. The second-order methods are applied in transmission electron microscopy analysis of blood capillaries in the(More)
Description of relations between spatial variability of microstructure and mechanical strength of alumina ceramics. assessment of the point-centred quarter method of plotless sampling in some New Zealand forests. 27 Acknowledgements We thank Chris Jonker for processing the heather image of Figure 1 at CWI as part of his honours thesis at the University of(More)
This paper proposes an approximative method for maximum likelihood estimation of parameters of Neyman-Scott and similar point processes. It is based on the point pattern resulting from forming all difference points of pairs of points in the window of observation. The intensity function of this constructed point process can be expressed in terms of(More)
This paper reports on spatial-statistical analyses for simulated random packings of spheres with random diameters. The simulation methods are the force-biased algorithm and the Jodrey-Tory sedimentation algorithm. The sphere diameters are taken as constant or following a bimodal or lognormal distribution. Standard characteristics of spatial statistics are(More)
The texture of binary spatial structures can be characterized by second-order methods of spatial statistics. The pair correlation function, which describes the structure in terms of spatial correlation as a function of distance, is of central importance in this context. Conventionally, the pair correlation function of stationary and isotropic random sets is(More)
