  • Patent number: 10984156
    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 fluid momentum conservation model and a proppant bed momentum conservation model that account for viscoelastic effects of the proppant-fluid mixture. The one-dimensional proppant transport flow model may also include a proppant momentum conservation model. In some cases the one-dimensional proppant transport flow model may account for any of settling and resuspension of a proppant bed and interphase momentum transfer between the proppant, proppant bed, and the fluid.

  • Publication number: 20200374281
    Abstract: A network service, program product and method that manages secure web application delivery. A service is disclosed that includes an interface configured to receive a request for a secure web application from a plug-in integrated into a web browser on a client computing device, wherein the request further includes a user credential token. Also included is a token processor that evaluates the user credential token and determines an associated customer domain server provided by a back-end service and a transport service that establishes a secure channel with the customer domain server, and forwards the request to the associated customer domain server and receives back a text-based data package. Once generated, the text-based data package is forwarded to the plug-in in response to the request.

  • Patent number: 10846463
    Abstract: Aspects of the disclosure relate to processing systems using improved techniques for determining a location of a DOM element. A computing platform may generate, based on a markup language template, a DOM element tree and/or an XPath expression corresponding to a DOM element to be located. Using the DOM element tree (or XPath expression), the computing platform may generate an element selector set corresponding to the DOM element. Using the element selector set, the computing platform may determine a first DOM element result corresponding to multiple elements. Using the DOM element tree, and after determining that the first DOM element result corresponds to multiple elements, the computing platform may generate an updated element selector set corresponding to a parent element and the DOM element. Using the updated element selector set, the computing platform may determine a second DOM element result using the updated element selector set.

  • Patent number: 10790081
    Abstract: Three-phase interleaved LLC and CLLC resonant converters, with integrated magnetics, are described. In various examples, the primary sides of the phases in the converters rely upon a half-bridge configuration and include resonant networks coupled to each other in delta-connected or common Y-node configurations. The secondary sides of the phases can rely upon a full-bridge configurations and are coupled in parallel. In one example, the transformers of the phases in the converters are integrated into one magnetic core. By changing the interleaving structure between the primary and secondary windings in the transformers, resonant inductors of the phases can also be integrated into the same magnetic core. A multi-layer PCB can be used as the windings for the integrated magnetics.

  • Publication number: 20190220182
    Abstract: Described embodiments provide systems and methods for controlling loading of web content with scrolling. A scroll manager of a web browser may determine a ratio of a first dimension of a portion of a webpage visible within a viewport of the web browser to a second dimension of an entirety of the webpage. Prior or to loading any other portion of the webpage, the scroll manager may set a scroll thumb dimension within a scroll bar of the web browser based on the ratio. The scroll manager may receive an interaction on the scroll bar of the web browser to arrive at a position within the webpage relative to the second dimension to be displayed within the viewport. Responsive to the interaction, the scroll manager may select a requested portion of the webpage corresponding to the first dimension about the position to render in the viewport.

  • Patent number: 9416631
    Abstract: In some aspects, a one-dimensional flow model is generated. The one-dimensional flow model can represent flow of a first fluid and a second fluid in a flow path in a well system environment. The one-dimensional flow model comprises an effective diffusion coefficient model for a composite fluid volume comprising the first and second fluids. The effective diffusion coefficient model calculates an effective diffusion coefficient for the composite fluid volume based on a difference between the respective densities and viscosities of the first fluid and the second fluid.
