  • Publication number: 20150095006
    Abstract: A simulation engine performs a mass-conserving Eulerian fluid simulation by manipulating the distribution of density between nodes associated with the fluid simulation. The simulation engine traces a velocity field upstream to identify the source of mass that currently resides at a given node. The simulation engine then adjusts (i) the density contributions to that source from adjacent nodes and (ii) the density contributions provided by that source to the given node. In doing so, the simulation engine maintains conservation of mass at a local level between nodes within a given neighborhood. As a result, mass is conserved at a global level. One advantage of the disclosed technique is that a fluid interface associated with the fluid simulation may appear physically realistic, because numerical errors typically caused by violations of conservation of mass may be eliminated.

  • Patent number: 8983817
    Abstract: A method for dynamic load balancing of a mesh, wherein the mesh is partitioned to find a solution using a plurality of processors, and wherein the partitions have become unbalanced. The present method allows large portions of the mesh to continue to progress towards a solution by only repartitioning a small percentage of the overall mesh. This is done by stripping cells along the partition interfaces using a marching method to form a free-cell region, repartitioning the free-cell region, and joining the repartitioned portions of the free-cell region with the remaining cells in a manner that will increase the efficiency of the solver.

    Abstract: In some aspects, a one-dimensional proppant transport flow model represents flow of a proppant-fluid mixture in a subterranean region. The one-dimensional proppant transport flow model includes a proppant momentum conservation model that balances axial proppant momentum in an axial flow direction of the proppant-fluid mixture against dynamic changes in transverse proppant momentum. In some instances, the proppant momentum conservation model can vary the axial proppant momentum, for example, to account for interphase momentum transfer between the proppant and the fluid.

  • Patent number: 8972231
    Abstract: A reservoir prediction system is disclosed that uses a kernel-based ensemble Kalman filter (EnKF) capable of representing non-Gaussian random fields characterized by multi-point geostatistics. The EnKF uses only the covariance and cross-covariance between the random fields (to be updated) and observations, thereby only preserving two-point statistics. The kernel-based EnKF allows the creation of nonlinear generalizations of linear algorithms that can be exclusively written in terms of dot products. By deriving the EnKF in a high-dimensional feature space implicitly defined using kernels, both the Kalman gain and update equations are nonlinearized, thus providing a completely general nonlinear set of EnKF equations, the nonlinearity being controlled by the kernel. By choosing high order polynomial kernels, multi-point statistics and therefore geological realism of the updated random fields can be preserved.

    Abstract: A flood modeling system defines virtual cells of a geographic region. Some of the cells, referred to as ā€œchannel cells,ā€ represent areas within a channel for a moving body of water, such as a stream or river. Other cells, referred to as ā€œland cells,ā€ represent areas external to the channels within the geographic region. The flow of water through the geographic region is modeled as a virtual flow of water through the channel cells and the land cells. For each time step, the system calculates the amount of water that virtually flows out of one cell into adjacent cells. The water estimated to virtually flow above ground represents flood water, and the estimates of such water can be used to generate an inundation map or initiate flood warnings.

  • Patent number: 8868383
    Abstract: There is provided a consumption energy calculating device which simulates power consumption of a heating and cooling appliance operated by a customer living in a house. A first receiver and a second receiver receive a demand response signal and an external environmental factor parameter. A pain level model shows a relationship between an indoor air temperature and a pain level. A first calculator calculates, when the appliance is not in operation, the indoor air temperature of a next sample time. A second calculator calculates, when the appliance is in operation, determines the indoor air temperature of the next sample time. A working sequence generator determines whether the appliance is or not to be operated during the next sample time. The power consumption determination unit determines power consumption consumed by the appliance before the next sample time and outputs data showing the power consumption.

  • Patent number: 8849630
    Abstract: Techniques for monitoring and predicting environmental operating conditions in a data center are provided. In one aspect, a method for real-time, three-dimensional analysis of environmental operating conditions in a data center includes the following steps. High spatial resolution three-dimensional measurements of one or more environmental variables in the data center made at a time t1 are obtained. Real-time measurements of the environmental variables in the data center made at a time t2, wherein t2 is later in time than t1, are obtained. The high spatial resolution three-dimensional measurements are combined with the real-time measurements to derive a model for the environmental variables in the data center at the time t2. The model is used to predict three-dimensional distributions of the environmental variables in the data center at the time t2. A base model can be created and used to derive the model for the data center at the time t2.

  • Patent number: 8849628
    Abstract: The software application is used to rank language translations and a method to implement those ranked language translations. The language translations are for textual or vocal phrases that a user wants to convert from its original language to a preferred language. The software application will refer to a variety of translation sources in order to create a set of applicable translations for a textual or vocal phrase. The software application will then rank each applicable translation with an accuracy score, which is weighed by three factors: the commonalities between the set of translation sources, a user input process, and a linguistic mapping process. Some methods to implement the ranked language translations include using accelerometer data from a electronic communication device to operate the software application, integrating a moderator into a conversation process, using subtitles in speech bubbles for a video chat, and using location data to communicate with different contacts.

Three relations that can be precomputed are exploited: (1) the relation between temperature and salinity throughout a water column, (2) the relation between temperature/salinity and geopotential, and (3) the relation between geopotential and velocity. The relations are stored in a form that allows efficient application through a cross-correlation matrix.
