  • Thermosphere-ionosphere model updating for low-earth orbits
    Patent number: 12511457
    Abstract: A computer-implemented method for determining an orbital effect on a low-Earth orbiting object includes, forming an ensemble of thermosphere-ionosphere state models to represent thermosphere-ionosphere state model uncertainty, assimilating measured thermosphere-ionosphere data into a select thermosphere-ionosphere state model of the ensemble in accordance with a Kalman gain derived from statistics of the ensemble, computing drag on the low-Earth orbiting object from elements of the assimilated select model of thermosphere-ionosphere state models and randomizing elements of the assimilated select thermosphere-ionosphere model in accordance with statistics of the ensemble to generate a new ensemble of thermosphere-ionosphere state models. A system is arranged to perform the method. A computer program product is arranged to cause one or more computers to perform the method.

  • Method and device for verifying the author of a short message
    Patent number: 11640501
    Abstract: A method for verifying whether a queried text of less than 500 characters has been compiled by an author, comprising the following steps: multivariate statistical analysis of the queried text, for example, PCA or PCoA, in order to generate a matrix of coordinates in a space with N dimensions; hierarchical clustering of the points of this space that can be represented by a dendrogram; verification of the author of the queried text on the basis of this clustering.

  • METHOD AND DEVICE FOR DETECTING STYLE WITHIN ONE OR MORE SYMBOL SEQUENCES
    Publication number: 20190050388
    Abstract: The invention relates to a method making it possible to detect style breaks within one or more symbol sequences (20). Said method includes the following steps: automatically slicing at least one so-called “symbol sequence” (2) into a plurality of windows (20A, 20B, . . .
