Abstract: The present invention is a method for exploiting a sedimentary basin using an updated stratigraphic model based on updating a stratigraphic model according to measurements performed in a basin. The method comprises steps of i) determining at least a first spatial distribution of the values of an attribute representative of the basin stratigraphy, and applying a classification method for converting this first spatial distribution to a first classified image; ii) performing a stratigraphic simulation with first parameter values of the simulation, deducing therefrom a second spatial distribution of the values of the attribute and applying the same classification method identically to determine a second classified image; iii) determining a distribution of local dissimilarities between the first and second classified images, and modifying the values of at least one of the stratigraphic simulation parameters to minimize an objective function formed from at least the local dissimilarity distribution; and iv) updating the stratigraphic model by performing at least one stratigraphic simulation with the modified simulation parameter values.

Abstract: The present invention relates to a crosslinkable electrolyte formulation comprising at least: —a lithium salt or a mixture of lithium salts—a hydrocarbon molecule comprising two thiol functions—an unsaturated hydrocarbon molecule comprising two C═C double bonds—a crosslinking agent, said crosslinking agent being a molecule carrying at least three C═C double bonds; in which the [C═C double bond]/[thiols] molar ratio is of between 1 and 1.1. The invention also relates to a process for the preparation of a crosslinked solid electrolyte by means of said formulation, and also to the use of said crosslinked solid electrolyte as solid electrolyte of an all-solid-state Li-ion battery or as component of the positive (posolyte or catholyte) or negative (negolyte or anolyte) electrode of an electrochemical system.

Abstract: The present invention is a method for determining the position of a source emitting at least one of a gaseous compound and particles in a geographical area, comprising measuring the gaseous compound concentration, the wind direction and speed for different predefined consecutive geographical positions to deviate by at most 45° from an instantaneous or average wind direction. At least one pair of a consecutive minimum and maximum of the curve is subsequently determined, and the position of the emission source is determined from the positions of the mobile measurement system corresponding to the maxima of the pairs, the time gaps between the maximum and minimum of the pairs, and average wind speeds and directions between the minimum and maximum of the pairs.
