Abstract: A method and mechanism for implementing a general purpose scripting language that supports parallel execution is described. In one approach, parallel execution is provided in a seamless and high-level approach rather than requiring or expecting a user to have low-level programming expertise with parallel processing languages/functions.

Abstract: In a non-destructive method for determining the internal structure of a heat conducting body, such as a cooling structure of a turbine blade, a flow medium is passed through the internal structure and the resultant thermal image on an external surface of the body is registered using a pixelised thermal image detector. Heat transfer coefficients and wall thicknesses of the internal structure are determined by means of a 1-,2-, or 3-dimensional inverse method that includes the numerical modelling of the surface temperatures using initial values for heat transfer coefficients and wall thicknesses and an optimization of the values using an iteration method. In a special variant of the method, the spatial geometry of the internal structure of the body is determined by means of the same inverse method and a geometry model that is optimised by iteration. No prior knowledge of the internal geometry is required.

The method also includes computing a path through the graph between the start point and the destination point.

Abstract: A method and engineering system by which relationships are automatically identifiable between CAD objects of different CAD models, where use of a transformation rule which maps points of the envelope geometry of a first CAD object of a first CAD model onto points in a second CAD model is used such that the points involved in the transformation rule each relate to the same modeled raw component. The transformation rule is applied to at least two CAD objects of the first CAD model. If the transformed points in the second CAD model are surrounded by a common-envelope geometry, this spatial relationship is interpreted as a grouping relationship. A hierarchical data structure is then formed automatically within the engineering system, taking account of the already recognized grouping relationship, and allowing synchronous data keeping.

Abstract: A Discrete Event System model created or provided in a time domain modeling and simulation environment and/or an event domain modeling and simulation environment may be divided into multiple independent regions, e.g. “subgraphs”, to achieve interleaved execution of the components from different domains. The subgraphs are automatically identified by the modeling and simulation environment during the compilation. Each subgraph consists of one or more interconnected event-driven components. Each subgraph is associated with an event calendar that controls the execution of the associated subgraph. Such multiple event calendar design enables multi-domain simulation, where event-driven components modeled by an event domain modeling environment and time-driven components modeled by a time domain modeling environment are simulated in an integrated fashion.
