  • Patent number: 10272337
    Abstract: The present invention causes a computer to function as a virtual space generating unit, a game screen displaying unit and a fluid displaying unit. A fluid displaying unit displays pseudo three-dimensional representation of fluid in virtual space on a game screen. And the fluid displaying includes a billboard setting unit and a two-dimensional simulation unit. A billboard setting unit sets a billboard which has a plain object and which rotates around a predetermined center point in the plain object so that the plain object faces the virtual camera in the virtual space. A two-dimensional simulation unit executes a two-dimensional simulation and displays a simulation result on the plain object.

  • Patent number: 10258303
    Abstract: The invention relates to an apparatus for determining a fractional flow reserve (FFR) value of the coronary artery system of a living being (3). A fractional flow reserve value determination unit (13) determines the FFR value by using an FFR value determination algorithm that is adapted to determine the FFR value based on a boundary condition and a provided representation of the coronary artery system, wherein the boundary condition is specific for the living being and determined by a boundary condition determination unit (12). Since the boundary condition determination unit determines a boundary condition, which is specific for the living being, and since the fractional flow reserve value determination unit not only uses the provided representation of the coronary artery system, but also the living being specific boundary condition for determining the FFR value, the accuracy of the FFR value, which is non-invasively determined, can be improved.

  • Patent number: 10241968
    Abstract: A method and system for simulating patient-specific cardiac electrophysiology including the effect of the electrical conduction system of the heart is disclosed. A patient-specific anatomical heart model is generated from cardiac image data of a patient. The electrical conduction system of the heart of the patient is modeled by determining electrical diffusivity values of cardiac tissue based on a distance of the cardiac tissue from the endocardium. A distance field from the endocardium surface is calculated with sub-grid accuracy using a nested-level set approach. Cardiac electrophysiology for the patient is simulated using a cardiac electrophysiology model with the electrical diffusivity values determined to model the Purkinje network of the patient.

  • Patent number: 10120836
    Abstract: Embodiments relate to gathering materials on an ocean surface. Initially, an initial distribution of material is determined based on observational sources, and the material is represented by particles in a numerical ocean model. Trajectories for the numerical ocean model are determined based on modeled surface currents data, and velocity gradients are computed along a corresponding trajectory of the trajectories for each of the particles based on the initial distribution. At this stage, deformation tensors are computed for each of the particles based on the velocity gradients, and a dilation map for the particles is generated based on a time step tensor of the plurality of deformation tensors for each of the particles. Collection of the material is monitored based on the dilation map.

  • Patent number: 10002456
    Abstract: Aspects described herein may provide improved water surface approximation by correcting a polygonal mesh (such as a projected grid mesh) at pixel and/or sub-pixel levels through application of a novel ray-casting method based on a modified version of Newton's method for finding roots. The ray-casting method may refine an initial condition determined based on the polygonal mesh and may iteratively develop a more accurate approximation of the water surface as described further herein. This improved approximation method may be suitable for both low-end and high-end GPUs. Due to lower computational complexity, the method may be utilized by low-end GPUs to improve quality while maintaining performance. The method may also be further enhanced with more advanced features such as low-cost multisampling anti-aliasing on higher-end GPUs to provide superior visualization of water surfaces and take full advantage of the additional processing power of such systems.
