Abstract: In current systems, only one consumer can personalize a product using a single session or at a single device (e.g., a computer, mobile device). In an embodiment, a method includes providing, at a user device via a network, a user interface displaying a three-dimensional (3D) model of a consumer product selected by a user. The method further includes customizing the 3D model of the consumer product based on selections and manipulations of the consumer product received at the provided user interface from at least two users. The method further includes, responsive to finalization of the customized 3D model by one of the users, submitting the customized 3D model for 3D printing. In this manner, multiple people can collaborate to create a single 3D printed product.

Abstract: Embodiments of the present invention simulate a real-world system by first generating a time dependent system of equations that represents the real-world system where the time dependent system of equations has a defined constraint. Next, the constraint is de-coupled from the time-dependent system of equations using a matrix representing an approximation of physics of the real-world system, the de-coupling generating a first system of equations representing the constraint and a second system of equations representing physics of the real-world system. In turn, the generated first and second systems of equations are solved and the real-world system is automatically simulated by generating a simulation using results from solving the first and second systems of equations.

Abstract: A computer-implemented method of computer vision in a scene that includes one or more transparent objects and/or one or more reflecting objects comprises obtaining a plurality of images of the scene, each image corresponding to a respective acquisition of a physical signal, the plurality of images including at least two images corresponding to different physical signals; and generating a segmented image of the scene based on the plurality of images. This improves the field of computer vision.

Abstract: A method comprising: simulating, in a lattice velocity set, movement of particles in a volume of fluid, with the movement causing collision among the particles; based on the simulated movement, determining relative particle velocity of a particle at a particular location within the volume, with the relative particle velocity being a difference between (i) an absolute velocity of the particle at the particular location within the volume and measured under zero flow of the volume, and (ii) a mean velocity of one or more of the particles at the particular location within the volume; and determining, based on the relative particle velocity, a non-equilibrium post-collide distribution function of a specified order that is representative of the collision.

Abstract: A method, system, and computer program product for correcting the contrast levels of a medical image of a vascular system is described. One of the methods includes identifying a global reference contrast level. The method includes for each image location which represents a location within the vascular system, determining a corrected contrast level by multiplying the original contrast level of that location by the ratio of the global reference contrast level divided by a local reference contrast level.

Abstract: Computer-aided design (CAD) models, and associated methods and systems, including topological and geometrical entities, graphical annotation information, and data structures storing non-native format semantic annotation information. Associated application programming interfaces (APIs) can include routines to return non-native format semantic annotation information stored in data structures associated with a native format CAD model. The APIs can include routines to identify whether annotations include data structures storing non-native format semantic annotation information, and to identify the types of the annotations. Graphical annotations can serve graphical display needs, while the semantic meanings from non-native CAD formats can be stored in placeholder data structures and, thus, be preserved. Manufacturing software applications can consume and act upon the semantic data via an API, thus, achieving automation benefits.

Abstract: Methods and systems display a computer-aided design (CAD) model with finish material specificity. An example embodiment begins by defining a CAD model in memory where the CAD model represents a real world physical object and the CAD model comprises a plurality of parts. Next, the example embodiment obtains spreadsheet data that relates material finishes with item numbers, and then, reformats the obtained spreadsheet data into a structured database. In turn, indications associating the parts or model elements of the CAD model with the item numbers are received and the CAD model is automatically displayed with the parts having the material finishes based on the structured database and the received indications of item numbers associated with the parts of the CAD model.

Abstract: The invention notably relates to a computer-implemented method of design of an industrial product wherein constraints between geometries of the industrial product are modeled with a graph of constraints comprising nodes and edges, a node representing a geometry and an edge representing a constraint between two geometries. The method comprising the steps of selecting at least one geometry of the product; computing a depth value of each node of the graph from a node representing the at least one selected geometry; identifying antagonistic constraint(s) in the graph, an antagonistic constraint being represented by an oriented edge wherein the depth value of the start node is larger to the depth value of the end node; reversing the identified antagonistic constraint(s); modifying the at least one selected geometry.

Abstract: Embodiments of the present invention relieve the burden on a product designer to setup simulations to validate a product design. These embodiments are directed to computer methods and systems for inverting a simulation process to validate a product design. The methods and systems configure a simulator with analysis methods. The methods and systems then provide product design parameters (operating environment conditions and design targets) that define scenarios likely experienced by a product in terms familiar to the product designer. The methods and systems, via the simulator, automatically determine simulations for validating the product design based on the provided product design parameters. To do so, the methods and systems map each of the design parameters to one or more analysis types, which are used by the simulator to select a sequence of analysis methods to define the simulations. The methods and systems execute the simulations to validate the product design.

Abstract: Techniques for simulating fluid flow on a computer that involve a stable entropy solver are described. The techniques include simulating activity of a fluid across a mesh, the activity of the fluid being simulated so as to model movement of particles across the mesh, storing, in a computer accessible memory, a set of state vectors for each mesh location in the mesh, each of the state vectors comprising a plurality of entries that correspond to particular momentum states of possible momentum states at a corresponding mesh location, simulating a time evolution of entropy of the flow by collecting incoming set of distributions from neighboring mesh locations for the collision operation, calculating by the computer scalar values in each location, determining outgoing distributions as a product of the collision operation and addition of a heat source, and modifying the flow by the computer performing for a time interval, an advection of the particles to subsequent mesh locations.
