This article discusses recent experiences with the Numeral Unit Spread Assessment Pedigree (NUSAP) system for multidimensional uncertainty assessment, based on four case studies that vary in complexity. We show that the NUSAP method is applicable not only to relatively simple calculation schemes but also to complex models in a meaningful way and that NUSAP is useful to assess not only parameter...

Given a Poisson potential field (or its derivatives) on a plane in free space, the entire ambiguity domain (i.e., the set of all source distributions that could generate the field) is easily reconstructed in the Fourier domain. The resulting models show a range of variability far larger than normally expected. In essence, potential fields in free space only contain enough information to determi...

Anisotropy in shales is becoming an important issue in exploration and reservoir geophysics. In this study, the crystallographic preferred orientation of clay platelets that contributes to elastic anisotropy was determined quantitatively by hard monochromatic X-ray synchrotron diffraction in two different shales from drillholes off the coast of Nigeria. To analyze complicated diffraction images...

Fractal patterns offer one way to represent the rough complexity of the natural world. Whilst they dominate many of our visual experiences in nature, little large-scale perceptual research has been done to explore how we respond aesthetically to these patterns. Previous research (Taylor et al., 2011) suggests that the fractal patterns with mid-range fractal dimensions (FDs) have universal aesth...

Goat Paddock in northern Western Australia is a *5 km-diameter impact crater of Eocene age excavated in gently dipping Proterozoic sandstones. Roughly radial gorges formed by post-impact erosion provide cross-sectional views of the wall and rim zone. The predominant structural theme is one of synclinal rim folding with broad zones in which bedrock strata were deformed by impact to steep, vertic...

A 2D finite-differences time-domain full-wave code is used to simulate the measurements of plasma filaments with fixed frequency O-mode reflectometry. The plasma is modeled by a linear slab plasma plus a Gaussian perturbation propagating in a direction that can vary from poloidal to radial. The plasma background density gradient is chosen in agreement with the steep edge transport barrier of H-...

We conducted a retrospective study of 36 cases of ameloblastoma from the files of Mittaphap Hospital in Vientiane Capital, Laos. Clinical findings showed an average patient age of 31.0 ± 3.8 years, with a slight male preponderance. Radiographically, all of the lesions showed multicystic radiotranslucency. Twenty-four patients underwent tumor resection and 12 underwent tumor enucleation. Of thos...
