Counting Figures in Planar Random Configurations [PDF]
, 1985 Random configurations are considered that are generated by a Poisson process of figures in the plane, and a recent result is used to derive formulae for the estimation of the number of figures, and their mean area and perimeter.

OPTIMAL RANDOM SAMPLING DESIGNS IN RANDOM FIELD SAMPLING [PDF]
A Horvitz-Thompson predictor is proposed for spatial sampling when the characteristic of interest is modeled as a random field. Optimal sampling designs are deduced under this context. Fixed and variable sample size are considered.

Random Field Models and near Well Reservoir Characterization [PDF]
, 2004 In Part 1 T-distributed random fields (TRF) are adressed. The main contribution of this paper is the introduction of a new, analytically tractable, heavy-tailed continuous random field model, namely the TRF model. In Gunning (2002) a related random field

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective High‐resolution MRI enables detailed assessment of intracranial vessel wall pathology in moyamoya vasculopathy. We aimed to classify adult moyamoya vasculopathy etiologies using high‐resolution MRI and to examine subtype‐specific associations between high‐resolution MRI features and ischemic infarction.

Geometric characterization of locally corroded surfaces in steel bridge girders
Frontiers in Built EnvironmentThe aging of steel bridge girders is often compounded by corrosion at girder ends due to leaking deck joints. With 6.8% of U.S. bridges in poor condition, there is an urgent need for accurate yet efficient methods to assess the residual load-bearing ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined. We

A Hardware Generator of Multi-point Distributed Random Numbers for Monte Carlo Simulation [PDF]
Monte Carlo simulation of weak approximations of stochastic differential equations constitutes an intensive computational task. In applications such as finance, for instance, to achieve "real time" execution, as often required, one needs highly efficient
