Abstract: A method and apparatus is disclosed whereby a point on an ear impression model to be labeled is selected and a shape context is determined for that point. This shape context is then compared to average shape contexts for different regions on a reference ear impression model, also referred to herein as an ear impression shape atlas. A cost function is used to determine the minimum cost between the shape context for the selected point and one of the average shape contexts. Once the minimized cost is determined, the region label corresponding to the average shape context having a minimized cost is assigned to that point. In this way, points on the surface of an ear impression are classified and labeled as being located in regions corresponding to the regions on the ear impression shape atlas.

Abstract: Space frames consist of combination of one or more basic modules to function as a decorative feature or a building element in architectural design. There are certain aesthetic criteria to meet on the design of a basic space frame module; space frame module, geometric regularity, and dimension regularity for all the angles and lengths between edges. Designers exercise their own creativity to develop space frame modules base on these criteria. The present invention relates to a hybrid algorithm based on evolutionary algorithm for graph encoding scheme (EAGES) and genetic algorithm (GA) to evolve the design automatically in relative small number of generations. The hybrid algorithm is a tool to architects and designers to rapidly produce aesthetically pleasing designs with the resources available to them.

Abstract: A method of creating and using a hardware independent communication interface block for block diagram environments is disclosed. The communication interface block includes user-selectable parameters controlling how a system being modeled by a block diagram communicates with image and data acquisition devices and control instruments or other electronic device interfaced with an external system. Based on the user selected parameters, the communication interface block calls an appropriate constructor to create an instrument object or acquisition device object which is used to enable communication with the control instrument or acquisition device respectively. The instrument object/acquisition device object calls a software driver appropriate for the hardware interface of the control instrument/acquisition device. The use of a common interface block provides scalability and ease of use to the block diagram environment when interacting with control instruments and acquisition devices.

Abstract: Disclosed is a method and system for modeling invariant relationships between flow intensity measurements in a distributed system. In the method, a measurement is randomly selected from a plurality of flow intensity measurements. The method searched for relationships between the randomly selected measurement and each remaining one of the plurality of flow intensity measurements, and each of the flow intensity measurements having a relationship with the randomly selected measurement is grouped into a cluster with the randomly selected measurement. The method than determines relationships between all of the flow intensity measurements in the cluster. This method is repeated with the remaining flow intensity measurements until all of the flow intensity measurements are grouped into a cluster.

Abstract: The present invention improves in one aspect the accuracy, efficiency, and robustness of fixed-step solvers when simulating a physical system that does not change in energy at the critical event. The present invention uses the energy of the error as the figure of merit in finding the first state of the system under the new constraints. The present invention enables a fixed-step solver to be more robust even when the critical event falls between two time samples. The present invention may also be applied to variable-step solvers. Moreover, the present invention may also be used to simulate a physical system when the energy changes at the critical event in the physical system.

Abstract: A hybrid evolutionary algorithm (“HEA”) technique is described for automatically calculating well and drainage locations in a field. The technique includes planning a set of wells on a static reservoir model using an automated well planner tool that designs realistic wells that satisfy drilling and construction constraints. A subset of these locations is then selected based on dynamic flow simulation using a cost function that maximizes recovery or economic benefit. In particular, a large population of candidate targets, drain holes and trajectories is initially created using fast calculation analysis tools of cost and value, and as the workflow proceeds, the population size is reduced in each successive operation, thereby facilitating use of increasingly sophisticated calculation analysis tools for economic valuation of the reservoir while reducing overall time required to obtain the result. In the final operation, only a small number of full reservoir simulations are required for the most promising FDPs.

Abstract: A first generation portion divides an object to be analyzed into a plurality of finite elements to generate element division data. A first calculation portion defines and calculates a plurality of meshes dividing the object to be analyzed into units larger than the finite elements. A second generation portion assumes that a friction layer which has a thickness of “0” and a friction coefficient between a conductive material and a composite material of a predetermined value less than 1 exists at the interface between the conductive material and the composite material, and the second generation portion generates mesh data. A second calculation portion uses various solvers to calculate the physical amounts produced in the object to be analyzed on the basis of the mesh data and outputs the analysis result. In other words, the second calculation portion performs a simulation of the behavior of the object to be analyzed.

Abstract: A method for gradually modifying a geological model representative of an underground reservoir to respect fixed average proportions of lithologic facies. A group of facies is selected and a subgroup of associated facies are selected. A transformation parameter is defined by the ratio between the average proportions of the facies of the association and the selection. Within the context of historical matching, a difference between measured dynamic data values and values calculated by a flow simulator from the geological model is measured. An optimization algorithm is used to obtain therefrom a new value for the transformation parameter that minimizes the difference and the transformation is applied to the lithologic facies of the selection. The modification can be applied to the entire model or to a given zone.

Abstract: A method and system for designing bottom hole assembly configuration. The system and method include modeling the bottom hole assembly by dividing complicated BHA configurations into independent modules and segments. Modules are bounded by two stabilizers where segments are bounded by bottom hole assembly components. A recursive process is used to derive solutions for each of the segments and modules. Only two unknowns (and two non-linear equations) are left when the recursive process reaches to the bit. The two unknowns are then solved by iteration.

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.

A method and system to compute a preconditioner for a coefficient matrix A that is compatible with the linear system of equations that provides basis function support over at least two mesh elements. Coupling of the preconditioner between partitions of a portioned mesh representation is only through basis functions at the partition boundaries.
