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: 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.

Abstract: Embodiments provide methods and systems for modeling mechanical features of a structural dynamic system. A method according to an embodiment provides, in computer memory, a finite element model representing a structural dynamic system. Next, in a processor coupled to the computer memory, a system of equations with a first term representing a linear combination of a mass, a stiffness, and a damping of the finite element model and a second term representing modal damping is solved. According to such an embodiment, the system of equations is solved using the Sherman-Morrison-Woodbury formula or a preconditioned iterative method. In turn, an improved 3D model of a real world object based on the finite element model is formed utilizing results of the solved system of equations with the finite element model and modal damping to model mechanical features of the represented structural dynamic system.

Abstract: Embodiments of the present invention provide an augmented reality by defining a model representing a real-world system. After defining the model, a plurality of model simulations are performed using the defined model which produce predicted field data that is stored in memory. In turn, data from one or more sensors in the real-world system is received and the defined model is calibrated using the received field data relative to the stored predicted field data. Then, an augmented reality of the real-world system is provided using the calibrated model.

Abstract: A computer-implemented method is provided for simulating a modal frequency response of a real-world object. The computer-implemented method includes dividing a plurality of excitation frequencies into a plurality of excitation frequency subsets, calculating modal frequency responses for at least a portion of the excitation frequencies in a given excitation frequency subset, and generating a simulation of the real-world object based at least in part on the modal frequency responses.

Abstract: In the proposed approach cluster elements (bins) are made available as a keypad in the form of a cluster map. The user directly selects the cluster element (bin) with a mouse, touch or actual keypad. For each of the associated attributes, a cluster map is available that orders the attributes from high-to-low by color or shade intensity. When a cluster element is selected in one cluster map, that same cluster element is also highlighted in other cluster maps. For each of the cluster maps, a value axis is available which shows the value of the parameter for the selected cluster element. In the case of numerical values, the high/low attribute pattern across the cluster maps is easily visible. The selected data objects in the cluster map are displayed in a separate widget.
Abstract translation: 在所提出的方法中，集群元素（箱）可以以集群映射的形式作为键盘提供。 用户使用鼠标，触摸或实际键盘直接选择群集元素（bin）。 对于每个相关属性，可以使用通过颜色或阴影强度从高到低排列属性的集群映射。 当在一个集群映射中选择了一个集群元素时，同一个集群元素也会在其他集群映射中突出显示。 对于每个集群映射，值轴可用，显示所选集群元素的参数值。 在数值的情况下，集群映射中的高/低属性模式很容易看到。 集群映射中选定的数据对象将显示在单独的窗口小部件中。
