    摘要： Radiation treatment planning and administration can include a Monte Carlo computer simulation tool to simulate photo-generated electrons in tissue. In the simulation, electrons that have left tissue voxels and entered air voxels can be evaluated to identify electrons that are circling along a spiraling trajectory in the air voxels. After at least one full spiraling circumference or other specified distance has been traversed using a detailed electron transport model, a simpler linear ballistic motion model can be instituted. This speeds simulation while accurately accounting for spiraling electrons that re-enter tissue voxels.

    摘要： A method and a non-transitory computer readable medium thereof for thermal analysis modeling are provided. The method includes establishing an electrothermal network π model on the basis of electronic modules of an electronic system to define a heat source, propagation paths and a common base of the electronic system. Observation points in the electronic system are defined, in which each observation point is located at an isothermal surface enclosing a volume surrounding a reference point, and where the reference point is the heat source or one observation point. A heat conduction temperature difference and a heat convection temperature difference are calculated according to a power density function, a thermal conductivity coefficient and a distance vector between the reference point and each observation point. A temperature distribution is established according to the heat conduction and the heat convection temperature difference and a defined temperature of the common base.

    摘要： In a method for simulating a physical property of a component model in the form of a computer accessible construction model of a technical structure, a mesh of a component model is automatically generated. The component model is first described by a fine mesh of finite elements, and, based on the fine mesh, the natural oscillation behavior of the component model is determined. Based on the natural oscillation behavior, at least one area of the component model is determined, whose finite elements are less deformed than those of another area of the component model. The determined area of the component model is then described by a coarser mesh of finite elements.

    摘要： A method to predict heat transfer coefficients for metal castings during quenching and/or cooling is provided. First, an initial set of HTC data are obtained from the computational fluid dynamics (CFD) simulation based on the metal casting geometry, initial metal casting temperature (distribution), quench bed/tunnel dimensions and set-up, and a given or baseline (standard) quenching condition including, but not limited to, air and/or gas flow velocity, air and/or gas flow direction relative to the work piece, air and/or gas temperature, air and/or gas humidity, etc. The initial HTC values for the entire surface of the work piece calculated from CFD can then be optimized by multiplying scale factors to minimize the error between the predicted temperature-time profiles and the experimental measurements for the given or standard/baseline quench condition. When the HTC values are optimized for a standard/baseline quench condition, a set of semi-empirical equations (or weight functions) can be used to quickly modify the standard/baseline HTC data for different quenching conditions (i.e., variations of quenching conditions from the baseline) without performing complete heat transferring and optimization calculations. A system and article of manufacture are also provided.

    摘要： A method of presenting a visual representation of a probable impact of a weather phenomenon to a location includes obtaining an impact function for the location by combining a weather function corresponding to a characteristic of the weather phenomenon with a damage function associated with the same characteristic. A graphic representation of an interest at the location is obtained. A visual representation of a probable impact of the weather phenomenon on the interest by modifying the graphic representation of the interest, where the modification is based on a predicted impact to the interest determined using the impact function.
