Spectral Spatial Variation [PDF]
AbstractAutomatic carcinoma detection from hyper/multi spectral images is of essential importance due to the fact that these images cannot be presented directly to the clinician. However, standard approaches for carcinoma detection use hundreds or even thousands of features.

Spatial variations of fundamental constants [PDF]
We show that observational limits on the possible time variation of constants of Nature are significantly affected by allowing for both space and time variation. Bekenstein's generalisation of Maxwell's equations to allow for cosmological variation of $alpha$ is investigated in a universe containing spherically symmetric inhomogeneities.

L’autocorrélation spatiale et les données de santé : une étude préliminaire [PDF]
L'analyse de l'autocorrélation spatiale cherche à mesurer jusqu'à quel point la variation dans un ensemble de données réparties dans l'espace est due aux relations decontiguïté.

Spatial variation in attributable risks [PDF]
The attributable risk (AR) measures the contribution of a particular risk factor to a disease, and allows estimation of disease rates specific to that risk. While previous studies consider variability in ARs over demographic categories, this paper considers the extent of spatial variability in ARs estimated from multilevel data with confounders both at

Systems approach towards surface water distribution in Kruger National Park, South Africa
There was concerted effort, especially between the 1960s and 1990s, to increase the distribution of surface water in Kruger National Park (KNP). As a consequence, most of the park was within easy walking distance of a permanent water source for large ...

Variational principlesvs. Spatial homogeneity
In this paper the homogeneity ansatz is imposed at the level of Einstein's equations and/or at the level of the action. The commutativity of these operations, as far as the resulting equations are concerned, is reinvestigated. The main result obtained is that, when the restrictions imposed by the isometry group are supplemented by the restrictions on ...
