Abstract: The invention notably relates to a computer-implemented method for selecting an appropriate decision by constraining options assessed with a model. The method comprises selecting a model capable of receiving inputs and providing output in response to an input; training a model with a set of data representing similar events; generating options that represent hypothetical events; computing target values by applying the trained model on the generated options; computing index for indexing the generated options and target values associated with the trained model; querying the said index for obtaining a selection of a set of options, the selection being performed according to a specific constraint; returning, as a result of the query, a subset of the set of the generated options, the subset being ranked according to the target values associated with each option.

Abstract: The invention notably relates to a computer-implemented method for querying a database. The database comprises 3D modeled objects that each represent a mechanical part. The database further comprises, for each 3D modeled object, a respective morphology signature. The method comprising: providing a query that includes a morphology criterion; returning, as results of the query, respective 3D modeled objects of the database, a respective 3D modeled object being returned based on an extent to which the respective 3D modeled object has a morphology signature that respects the morphology criterion. Such a method improves the field of searching mechanical parts in a database.

Abstract: A computer-implemented method for designing, with a CAD system, a 3D modeled object representing a mechanical part. The method includes displaying a B-rep having faces and edges and representing at least a part of the mechanical part, selecting, by graphical user interaction, at least one face of the B-rep, and, automatically by the CAD system, recognizing a set of faces including the at least one face and representing a bump. The recognizing includes determining a first set of faces representing a depression and a second set of faces representing a protrusion, and selecting, among the first set of faces and the second set of faces, a set of faces having a shortest boundary curve perimeter and being different from both the selected at least one face and the B-rep. The first set of faces and the second set of faces both comprise the at least one face.

Abstract: A method includes simulating a process, with computer-based software, to produce virtual data about the process; identifying process parameters for a real-world version of the process; providing a real-world sensor to sense a parameter associated with the real-world version of the process; receiving sensor readings from the real-world sensor while the real-world version is being performed; and training a machine-learning software model to predict a behavior of the real-world sensor based on the virtual data about the process, the process parameters, and the sensor readings.

Abstract: The disclosure notably relates to a computer-implemented method for 3D reconstruction. The method comprises providing a 3D point cloud representing a real object. The method also comprises fitting the 3D point cloud with parametric surfaces. The method also comprises defining a partition of the parametric surfaces into oriented facets which respect intersections between the parametric surfaces. The method also comprises determining, among the oriented facets of the partition, a set of facets that represents a skin of the real object. The determining comprises minimizing an energy. The energy includes a data term and a constraint term. The data term increasingly penalizes discarding facets, as a level of fit between a discarded facet and the 3D point cloud increases. The constraint term penalizes formation of non-skin geometry by kept facets. Such a method provides an improved solution for 3D reconstruction.

Abstract: The invention notably relates to a computer-implemented method, performed by a server storing an index of a search engine, for sending, to a client, the URLs of pages of a Web corpus that relates to a theme. The method comprises receiving, from the client, a structured query that corresponds to the theme, the structured query consisting of a disjunction of at least one keyword; determining in the index the group that consists of the URLs of all pages that match the query; and sending to the client the URLs of the group as a stream.Such a method improves the building of a thematic Web corpus.

Abstract: The disclosure notably relates to a computer-implemented method for designing a three-dimensional (3D) finite element mesh of a 3D part that comprises a lattice structure. The method includes superposing a regular tiling of cells with the solid representation of a 3D part, partitioning the cells into two groups, a first group of cells, each in contact with the solid representation of the 3D part, and a second group of cells, none in contact with the solid representation. The method also includes finite element meshing a boundary of the solid representation, extracting a boundary finite element mesh of the first group of cells, computing a Boolean union of the finite element mesh and the extracted boundary finite element mesh, finite element meshing a volume of the computed Boolean union and merging the finite element meshes of meshed volume of computed Boolean union and the cells of the second group of cells.

Abstract: The disclosure notably relates to a computer-implemented method for designing, with a CAD system, a 3D modeled object representing a mechanical part. The method includes obtaining a B-rep representing the mechanical part. The B-Rep has faces and edges. The method further includes obtaining a first set of faces and a feature type. The feature type is either a depression feature type or a protrusion feature type. The method further comprises, automatically by the CAD system, recognizing a second set of faces within the first set of faces. The second set of faces represents a feature of the provided feature type. This constitutes an improved method for designing a mechanical part.

Abstract: A computer implemented method for designing a 3D modeled object that represents a mechanical part. The method comprises selecting a group of faces of the B-Rep, defining a trajectory for each respective face of the group of faces, computing, for each face of the group of faces, a respective swept volume, the swept volume corresponding to the volume swept by the respective face with respect to the trajectory, assigning a material removal label or a material adding label to each swept volume, according to the position of the swept volume at the respective face with respect to the interior of the 3D modeled object, and updating the B-Rep with a material removal volume and then a material adding volume. The method improves the design of a 3D modeled object.
