Abstract: A computer-implemented method for determining characteristics of a patient that influence a progression of a disease of the patient. The method includes, while training a neural network with a provided dataset, for each transition of the multi-state model, and for each characteristic, determining a respective quantification of an impact of the characteristic on the results of the neural network. The method includes, for each transition, identifying a list of characteristics of the set of characteristics, and, for each given characteristic of the identified list, determining a relationship between the given characteristic and probabilities of transition. The method includes providing the identified lists and the determined relationships that influence the progression of the disease of the patient. Such a method forms an improved solution for determining patient's characteristics that influence patient disease progression.

Abstract: A computer-implemented method for designing a 3D model, which includes providing an initial 3D model in a 3D scene including at least one extruded section, being defined by a set of parameters, receiving a user sketch on the plane perpendicular to the sight of view direction, at each iteration: modifying at least one of said parameters, thereby obtaining a modified 3D model, performing a perspective projection, on a plane perpendicular to the sight of view direction, of the modified 3D mode, thereby obtaining a 2D visible wireframe including the visible inner and outer edges of the modified 3D model, computing an energy including a first term which penalizes an inconsistency between the modified and the initial 3D model, and a second term which penalizes a mismatch between the 2D visible wireframe and the user sketch, said parameters being modified to minimize said energy, and outputting the modified 3D model.

Abstract: A computer-implemented method for determining a machine-learning function configured for taking an input 3D scene and for outputting one or more camera viewpoints each for generating a respective 2D rendering of the 3D scene. The method includes obtaining a library having 3D scenes. The method includes, based on the library, forming a first dataset for training a first neural network configured for outputting a camera position and forming a second dataset for training a second neural network configured for outputting a camera orientation. The method includes training the first neural network based on the first dataset and training the second neural network based on the second dataset. Each camera viewpoint outputted by the machine-learning function includes a camera position and a camera orientation. Such a method forms an improved solution for outputting one or more camera viewpoints of a 3D scene.

Abstract: Disclosed are techniques for scalar solvers in flow simulations that include simulating using a scalar lattice velocity set in a computing system, movement of scalar particles representing a scalar quantity in a volume of fluid, with the scalar particles carried by flow particles of the volume of fluid, and with the movement of the scalar particles causing collisions among the scalar particles; and evaluating, a non-equilibrium post-collide scalar distribution function of a specified order that is representative of the scalar collision.

Abstract: A computer-implemented method automates generation of a representative volume elements (RVE) unit fuel cell model. A finite element model (FEM) of a unit cell of a proton exchange membrane fuel cell (PEMFC) is received. Input identifying a unit region with a discretization of the FE unit cell is received. A mesh rule corresponding to the unit region is received. An RVE unit region corresponding to the FE unit region is generated based on the FE unit region and the mesh rule.

Abstract: A computer-implemented method for designing a manufacturing product having one or more mechanical functionalities. The method includes obtaining a first instance of a CAD model and a mesh representing a target boundary shape of the manufacturing product and determining a second instance of the CAD model. The CAD model includes a feature tree having a plurality of continuous CAD parameters, and a set of one or more parameterization constraints which specifies the one or more mechanical functionalities. The first instance includes a first value and the second instance includes a second value for each continuous CAD parameter, respectively. The determining of the second instance consists of computing the second values by modifying at least part of the first values to minimize a shape dissimilarity metric between a boundary shape represented by the first instance of the CAD model and the target boundary shape.

Abstract: A distributed database processing system for a database composed of data records organized into tables which processes unique index atoms consistently and concurrently. Each attempt to insert a new key value into such a unique index atom in any given node is routed to a unique index atom chairman for processing. The chairman determines whether the request will be granted. If the request is not granted, the requesting unique index atom continues to try to submit the insert. If the request is granted, the requesting unique index atom modifies the content thereof and broadcasts a replicated given unique index atom all other nodes that contain the replicated unique index atom.

Abstract: A positioning of a digitally modeled 3D object is assisted in a particular method which also includes obtaining a first digitally modeled 3D object having a 3D position in a 3D scene, rendering a projection of said first digitally modeled 3D object on a screen according to a first axis and a first viewpoint, and while modifying, upon user action, the 3D position of the first digitally modeled 3D object along the first axis, automatically scaling the first 3D object in order to keep constant the projection of the moved object on the screen.
