TL;DR: It is shown that this truncated gaussian method ensures consistency for the model in terms of the indicators variograms and cross variograms, and also how the method can deal with a complex 3D non stationarity.
Abstract: The truncated gaussian method [6] [8] has been widely used in the past in order to simulate indicators. In this paper we investigate the potential and limitations of this method, from a geostatistical point of view and also from a practical one. First we present the method in detail including the hypotheses behind it. In particular we show that this method ensures consistency for the model in terms of the indicators variograms and cross variograms. Examples of the types of variograms that can and cannot be fitted using this method are presented. Then we discuss how to take into account vertical non stationarity for the indicators, as this seems to be the usual case (due to sequential evolutions in a sedimentary unit). This point will be illustrated via several examples. We then explain how the method can deal with a complex 3D non stationarity, and discuss the practical problems of using it in this case.

TL;DR: A generalisation of distance-based and lexicographical-based approaches is proposed, allowing the extension of morphological operators to colour images for any colour representation and for any metric distance to a reference colour.

TL;DR: In this article, the Least Squares Support Vector Machine (LSSVM) algorithm is employed to present several numerical models for calculation/estimation of the clathrate hydrate dissociation conditions of methane, carbon dioxide, nitrogen, and hydrogen in the presence of three most-widely used water “soluble” organic promoters including tetrahydrofuran (THF), 1,4-dioxane, and acetone.

TL;DR: In this article, micro-macrosegregation calculations have been performed for a rectangular cavity containing either a Pb-48 wt pct Sn alloy or a Sn-5 wtpct Pb alloy, and the numerical results calculated with a finite volume method and a finite element method were compared with experimental results obtained by Hebditch and Hunt.
Abstract: Micro-macrosegregation calculations have been performed for a rectangular cavity containing either a Pb-48 wt pct Sn alloy or a Sn-5 wt pct Pb alloy. The numerical results calculated with a finite volume method (FVM) and a finite element method (FEM) are compared with experimental results previously obtained by Hebditch and Hunt. The two methods are based on the same average conservation equations governing heat and mass transfer and the same assumptions: lever rule, equal and constant density of the solid and liquid phases (except in the buoyancy term), permeability of the mushy zone given by the Carman-Kozeny relation, and no transport of the solid phase. Although the same parameters are used in both calculations, small differences are observed as a result of the different formulations. In particular, the instabilities appearing in the mushy zone (channels) of the Sn-5 wt pct Pb alloy are more pronounced with the FVM formulation as compared with FEM, whereas the opposite trend is observed for the Pb-48 wt pct Sn alloy. Nevertheless, the final segregation maps at the end of solidification compare fairly well with the experimental findings.
