摘要： A computer-implemented method for designing a 3D modeled object of a physical prototype of a product. The 3D modeled object includes a wireframe based on at least one character line. The method includes computing a segmentation of an obtained mesh, therefore obtaining at least two regions from the obtained mesh and at least one boundary polyline between the at least two regions. Then the method comprises transforming each of the at least one boundary polyline in at least one character line. The method further comprises computing a network of the at least one character line, the network of the at least one character line forming the wireframe of the 3D modeled object.

摘要： The invention relates to a method and a system for computer-assisted maintenance of a device to be maintained, comprising a storage in a first system, which storage is implemented progressively when in use an operating system comprising the device to be maintained, of operational data associated with the said operating system. For a maintenance processing method, which is to be implemented by the second system (8) by applying a processing algorithm (38) to a set of operational data, the maintenance system uses a homomorphic or partially homomorphic cryptosystem (28) to obtain a modified maintenance processing algorithm (40) which makes it possible to obtain an item of predictive or corrective maintenance information in encrypted form, from a set of protected operational data comprising a first subset of encrypted operational data ((D1)H) by a means of a cryptosystem encryption method (28), and a second subset of plain data (D2) from the said set of operational data.

摘要： A geomechanically integrated model of stimulated rock volume (SRV) of subsurface formations in an area of interest for hydrocarbon production is formed. The methodology for forming the model takes into account geomechanical effects of interest and potential significance which occur over different dimensional scales. The methodology incorporates into the model fault perturbations which are present at a regional or seismic scale of from hundreds to thousands of meters, as well as layer stress occurring at a much smaller hydraulic fracture simulation scale of fractions of meters or meters. The methodology accommodates the differing representations of the subsurface grids used in previous models to represent these different geomechanical effects. Complex grid meshing and computer processing are avoided, improving computer operation and saving computer processing time.

摘要： Systems and methods for deriving material coefficient values from physical measurements of physical objects are described. These physical measurements can provide material test data. In one embodiment of a method described herein, the material test data can be used to calculate a first subset of material coefficients for use in one or more material models from material test data; the method can define a set of optimization parameters and define a set of relationships between a second subset of the material coefficients and the set of optimization parameters such that values of the material coefficients in the second subset of material coefficients can be calculated from the set of optimization parameters, wherein the first subset and the second subset include all of the material coefficients in the one or more material models and the set of optimization parameters have fewer parameters than a total number of coefficients in the first subset and the second subset; then the method can calculate optimum values of the optimization parameters to yield an optimum fit of the one or more models to the material test data, the optimum fit based on optimum material coefficients calculated from the calculated optimum values of the optimization parameters.

摘要： A method may be used to correct a condition present in a patient. The method may include obtaining a first bone model of a first bone of one or more bones of the patient's foot and using at least the first bone model to generate a cutting guide model. The cutting guide model may define a first bone engagement surface shaped to match a first contour on the first bone, and a first guide feature that, with the first bone engagement surface overlying the first contour, is positioned to guide resection of the one or more bones as part of a surgical osteotomy for correcting the condition. The surgical procedure may be selected from a first group consisting of a bunion correction osteotomy, an Evans calcaneal osteotomy, and a medializing calcaneal osteotomy. The first bone may be selected from a second group consisting of a metatarsus, a cuneiform, and a calcaneus.

摘要： A computer system controls access to data. A request is received from an entity to access data comprising a primary data object corresponding to a physical item. One or more secondary data objects included in the primary data object are identified, wherein the one or more secondary data objects correspond to physical components of the physical item. Access requirements for the primary data object and the one or more secondary data objects are determined. In response to determining that the access requirements are satisfied by the entity, the entity is granted access to the data comprising the primary data object and the one or more secondary data objects. Embodiments of the present invention further include a method and program product for controlling access to data in substantially the same manner described above.
