  • Patent number: 8271237
    Abstract: Improved 8-node hexahedral elements configured for reducing shear locking in finite element method are disclosed. According to one aspect, aspect-ratio based scale factors are introduced to modify partial derivatives of the isoparametric shape function of the hexahedral element with respect to isoparametric dimensions, respectively. The modified derivatives are used for calculating the Jacobian matrix thereby the rate-of-strain. The scale factor is configured such that no changes for a perfect cubic solid element (i.e., element having aspect ratio of 1 (one) in all three spatial dimensions), while significant changes for element having poor aspect ratio. In other words, elements with poor aspect ratio are mapped to a perfect cubic element using the aspect-ratio based scale factors. According to anther aspect, off-diagonal components in the local Jacobian matrix are directly modified by cancelling terms related to spurious shear deformation modes.

  • Patent number: 8265914
    Abstract: A system, method and memory medium for injecting positional information into a geological data set for improved modeling of surfaces in a geological formation. The method involves: (1) displaying a cross section of the formation through a selected subset of wells, where the displayed cross section includes well picks for the selected wells; (2) opening a gap in an unconformity of the displayed cross section, where the gap is opened at one or more wells that intersect the unconformity, where the gap represents non-deposition and/or material that is missing from the formation due to erosion; (3) receiving user input specifying positions of tops within the gap; and (4) closing the gap, where closing the gap includes calculating positions of restored tops based on the positions of the tops specified within the gap, where the positions of the restored tops are usable to model one or more surfaces in the formation.

  • Patent number: 8239174
    Abstract: In a design support apparatus, a storage unit stores location data of an assembly including a first member long and flexible and a second member connected to the first member and having a larger cross-sectional shape than that of the first member within a product, and respective positions of installed objects. A geometric center calculation unit virtually extends straight lines from a point on a route along which the first member passes, radially in directions normal to a tangential direction of the route, virtually positions points where the straight lines come into contact with the installed objects, and calculates a geometric center from the positioned points. A route change unit changes the route such that the first member passes the calculated geometric center. A verification unit verifies whether or not the assembly interferes with any of the installed objects during passage of the first member along the changed route.

  • Patent number: 8195443
    Abstract: A user interface to a network simulator facilitates the use of application layer parameters and application layer logic. The user interface is configured to allow the user to define the input in a graphic form, or a text/programming form, or a combination of both. Preferably, the user interface provides common graphic forms for both inputting the data to the simulator as well as for displaying the resultant data from the simulator, thereby easing the progression from the analysis of output from one simulation to the generation of new input for a subsequent simulation.

  • Patent number: 8180609
    Abstract: The computer-implementable method allows for the fast creation of a multi-unit interval data signal suitable for simulation. The created signal represents the output of an otherwise ideal Discrete Time Filter (DTF) circuit, and the quick creation of the signal merely requires a designer to input the number of taps and their weights without the need of laying out or considering the circuitry of the DTF. A matrix is created based on a given data stream, and the number of taps and weights, which matrix is processed to create the multi-unit-interval data signal. Noise and jitter can be added to the created signal such that it now realistically reflects non-idealities common to actual systems. The signal can then be simulated using standard computer-based simulation techniques.

  • Patent number: 8108184
    Abstract: Described are software tools and techniques for use in power system operations and control, enabling direct non-iterative solution and estimation of the state of a power system. Knowledge of the state of a power system is essential for secure, reliable and efficient operation of the system. Power system measurement data including the phasor data, as well as power system parameter and topology data are utilized. A set of redundant nonlinear equations, quadratic or third-order in form is formulated. The nonlinear equations are then solved directly for the state of the power grid. The methodology is non-iterative and offers a direct solution that does not depend on initial guess values or convergence of iterations, thus offering a more robust tool for energy management systems and power systems operation and control.
