Abstract: Techniques are provided for the transfer of data (e.g. electromagnetic losses and temperature for an electro-thermal simulation) between domains (e.g. 2D regions, 3D regions) with dissimilar topologies, e.g. to represent a physical object. Meshes from 2D and 3D regions of respective simulation models involved in the data transfer are projected onto and through one another. For profile preserving (e.g., temperature, convection coefficients, mesh displacements, etc.) and conservative (e.g., force, mass, or thermal energy, etc.) data transfers, shape functions and area/volume fractions are used in mapping weight generation, respectively. These weights are later used to generate field values on the mesh of the target simulation model, using data from the mesh of the source simulation model. Related apparatus, systems, techniques and articles are also described.

Abstract: The techniques disclosed herein help designers find interesting designs for small electrical, mechanical, and/or hydraulic mechanisms by exhaustively enumerating the design space given a library of components and a maximum number of components allowed per design. Some embodiments work by creating a design space grammar of designs, solving the equations associated with parts of the grammar, and putting the solutions into equivalence classes. This dramatically reduces the number of designs that have to be evaluated to see if they satisfy the design criteria. The result is often a small number of base designs that show the range of possible solutions to the design problem.

Abstract: Design parameters for PDC drill bit are correlated to instances of backward whirl, where backward whirl is detected along a lateral axis in the frequency domain during downhole drilling. Two regimes of backward whirl are described and detected—cutting-induced backward whirl and friction-induced backward whirl—where each regime has different characteristic frequencies, detection methods, and mitigation guidelines. Design parameters are quantified by gauge fullness, drilling efficiency (DE), and whirl index (WI). Design guidelines to mitigate backward whirl are generated by correlating design parameter quantifiers and instances of backward whirl, including both cutting-induced backward whirl and friction-induced backward whirl. Potential drill bit designs are then validated against the generated guidelines in order to mitigate backward whirl in future drilling runs.

Abstract: Global fluence estimators may be calculated on accelerators and processors for neutron and photon Monte Carlo transport. Monte Carlo random walk simulation may be performed on the processors and the calculation of a Volumetric-Ray-Casting (VRC) estimator may be offloaded to the accelerators. The VRC estimator may modify an expected-value estimator to extend a pseudo-particle ray along the direction of the emitted particle from source and collision event through not only the event volume, but also through all volumes that describe the problem geometry. Additionally, many pseudo-particle rays may be sampled per event, rather than just a single pseudo-particle ray per event, in order to provide more complete angular coverage.
