  • Publication number: 20240071577
    Abstract: Methods, computer systems, and apparatus, including computer programs encoded on computer storage media, for predicting an exchange-correlation energy of an atomic system. The system obtains respective electron-orbital features of the atomic system at each of a plurality of grid points; generates, for each of the plurality of grid points, a respective input feature vector for the electron-orbital features at the grid point; and processes the respective input feature vectors for the plurality of grid points using a neural network to generate a predicted exchange-correlation energy of the atomic system.

  • Patent number: 10808528
    Abstract: An example method for analyzing drilling fluid used in a drilling operation within a subterranean formation may include receiving a drilling fluid sample from a flow of drilling fluid at a surface of the subterranean formation. A chemical composition of the drilling fluid sample may be determined using a mass spectrometer. A formation characteristic of the subterranean formation may be determined using the determined chemical composition. Determining the chemical composition of the drilling fluid sample may include determining the chemical composition of at least one of extracted gas from the drilling fluid sample and a liquid portion of the drilling fluid sample.

  • Patent number: 7711235
    Abstract: In one embodiment a fiber tray include an arrangement of retaining slots configured to receive retaining clips in a variety of different orientations and sizes. Retaining clips may have standardized sizes to correspond with the arrangement of retaining slots and to secure a variety of components to the fiber tray in different locations and orientations. Fiber management means may be provided to guide fiber optic cable from the components in a variety of orientations and locations. The fiber tray may be configured to move between a stowed position within a node housing in which the mounting surface of the tray faces downward and an access position in which the tray faces upward. The tray may be transparent to allow a technician to view the fiber arrangement without moving the tray from the stowed position.

  • Patent number: 7564455
    Abstract: A system and process that incorporates hardware and software as elements to be combined with procedures and processes to obtain, format, store, combine, control, display, record, and visualize dynamic scenarios by interacting with accurate, realistic models and actual events within, on, and above a three-dimensional surface to be observed or modeled. The present invention software and process is capable of displaying extremely high resolution terrain models and imagery in real time over the entire surface of the planet, as well as a large number of moving entities and their associated graphical models. These features, combined with a network application programming interface (API), make the present invention suitable for flight simulation out-the-window displays, command and control scenarios, and mission review or rehearsal.
