Geoaesthetics is the project of making aesthetic sense of nature through geological phenomena. The aesthetic appreciation of nature has recently become urgent because of the serious influence of the natural environment on human beings. The author’s geoaesthetical research is categorized into three problems: art in geology or geology in the arts as the close relationship between art and geology,...

The modeling of hydrocarbon reservoirs and of aquifer-aquitard systems can be separated into two activities: geological modeling and fluid flow modeling. The geological model focuses on the geometry and the dimensions of the subsurface layers and faults, and on its rock types. The fluid flow model focuses on quantities like pressure, flux and dissipation, which are related to each other by rock...

fOR the Past 24 yeaRs, BIOlOgIsts haVe studied lichens in the Great Lakes national park units in considerable detail (see map), including floras and chemical element surveys, for biodiversity and air quality assessments. They have studied lichens because they are sentinel species indicating ecosystem health, and because they are excellent biomonitoring and bioindicator species of air quality. T...

In the past 10 years an abundance of new models aimed at finding a better or even the ultimate solution for the structure and evolution of the Mediterranean Tethys have been published. These models are based on new geophysical (mainly paleomagnetic) results, refined stratigraphic and facies data, and sometimes even on detailed geochemical analyses. They were constructed with the help of paleaog...

Injection of CO2 in geological reservoirs or deep aquifers is nowadays studied to regulate the global warming by limiting the amount of greenhouse gases emitted by human activity into the atmosphere. CO2 is captured from exhaust gas in power plants or industrial units and then stored in underground geological reservoirs. The experience available in the oil industry concerning CO2 injection clea...

This study proposes a segmentation procedure based on multivariate texture to extract spatial objects from an image scene. Object uncertainty is quantified to identify transitions zones of objects with indeterminate boundaries. The Local Binary Pattern (LBP) operator, modelling texture, is integrated into a hierarchical splitting segmentation to identify homogeneous texture regions in an image....

Molecular estimates of evolutionary timescales have an important role in a range of biological studies. Such estimates can be made using methods based on molecular clocks, including models that are able to account for rate variation across lineages. All clock models share a dependence on calibrations, which enable estimates to be given in absolute time units. There are many available methods fo...

At 2600 km diameter, the South Pole-Aitken (SPA) basin is the largest on the Moon and has profoundly influenced lunar crustal configuration and subsequent evolution [1-4]. SPA is significant for two principal reasons: 1) its immense size suggests that it has excavated most or all of the lunar crust at its target site, thus giving us a window into the very deep lunar interior; 2) because it is t...
