Abstract: A method and system for analyzing performance of a turbine. The turbine optimizer allows a user to evaluate the current performance of their turbine with its current configuration and the future performance of their turbine with a modified configuration. The turbine optimizer determines the current performance characteristic of the turbine based on the current configuration information. Upon receiving from a user a request to display the future performance characteristics, the turbine optimizer calculates the performance characteristics for that turbine if various modifications are made to its configuration. The turbine optimizer may provide a graph that illustrates the current performance characteristics and future performance characteristics with those modifications. The turbine optimizer may also calculate various financial estimates based on the current operating characteristics or future operating characteristics of the turbine.

The modifier function modifies a system memory on the specified computing device that stores the heterogeneous program.

Abstract: An efficient parallel event simulation method is implemented by simulating blocks of M edge events, where M is approximately equal to e logeN, and N being the number of interconnected processing elements. Following a simulation iteration, each processing element shares information with adjacent processing elements that relates to events that the processing elements simulated which may affect the simulation of events at the neighbor processing elements. When the communication reveals that the information that is shared by a neighbor processing elements is different from the information that the processing element assumed, then the arriving information is kept and the simulation process is repeated. In executing the repeated simulations of a block, the same random variable values are employed. When all of the processing elements find that the arriving shared information is the same as the information already known to the receiving processing element, simulation of the block ends.

Abstract: A method and system for creating a simulation authoring environment. Specifically, the present invention discloses a method and system for creating a simulation application that simulates a real-life interaction with a network device. In one embodiment, a real command-line interface with the device is monitored at a server computer. The interface, including the line-commands and their outputs are captured. The line-commands for the particular communication sequence are summarized and grouped into steps. Also, the line-commands can be edited. New line-commands can also be introduced into the communication sequence. Additionally, the server computer re-executes the communication sequence in order to determine all the valid permutations associated with the communication sequence.

Abstract: A mill roll analysis system is described that includes a user interface module, a structural analysis engine, and an analysis control script. The user interface module receives mill roll design data from a remote user via a computer network. The analysis control script automatically directs the structural analysis engine to define and evaluate an appropriate analytical model for the mill roll design based on the mill roll design data. The mill roll analysis system presents an intuitive web-based interface for capturing the mill roll design data, and may present predefined mill roll applications and mill roll types for selection for the user. As a result, the remote user need not be familiar with the underlying analytical modeling techniques, which may be highly-complex by nature. Consequently, a user may utilize the system to evaluate and improve mill roll design in order to achieve increased product performance.

Abstract: An open system for multiple discrete, geographically disperse simulation engines to communicate with each other across a distributed electronic network, such as the Internet, comprises a portal accessible to the simulation engines over the network. Local portions of the simulation may be run separately by each simulation engine, and the output data files are stored on and managed by the portal. A co-simulating engine may request an output data file stored by the portal and use that data as input for its downstream portion of the simulation. In this fashion, multiple geographically disperse simulation engines can test bench their designs in an open, network centric simulation environment.

Abstract: The invention relates to the simulation of the deformation of materials, notably of soft body tissues. An apparatus comprises a memory (MEM, NT) storing data as to the position of an object, recorded at the vertices of a grid pattern, and data for force to be exerted on the object. A computer (?P, MT) evaluates new positions of the vertices, as a function of a force exerted globally and mechanical parameters of the material. According to the invention, this computer comprises a module for calculating, for each mesh, a deviation between the current length of an edge and its previous length, and the force data at each vertex of the mesh. Another module calculates, for each vertex, new positional data relating to this vertex as a function of the forces exerted thereon and its previous position.

Abstract: The present invention provides a meshing method, called grafting, that lifts the prior art constraint on abutting surfaces, including surfaces that are linking, source/target, or other types of surfaces of the trunk volume. The grafting method locally modifies the structured mesh of the linking surfaces allowing the mesh to conform to additional surface features. Thus, the grafting method can provide a transition between multiple sweep directions extending sweeping algorithms to 2¾-D solids. The method is also suitable for use with non-sweepable volumes; the method provides a transition between meshes generated by methods other than sweeping as well.

The delay reduction process recursively reduces the delay of critical fanins of a selected. Furthermore, in one embodiment, the fanins of the selected node are sorted according to their slack values.

Abstract: The present invention is directed to methods for reliability simulations in aged circuits whose operation has been degraded through hot-carrier or other effects by allowing design rules on degradation to be included in the netlist. Once the hot-carrier circuit simulation is launched, the rules are checked and the reliability design rule violations are reported. The process can be performed on either the layout or schematic window. The design rule criteria can be any device parameter and can be expressed in absolute or relative terms. The criteria can be based on device type, model card name, instance geometry, or temperature. Additionally, values can be set prior to beginning the simulation.
