Patent number: 10984156Abstract: 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.Type: GrantFiled: August 7, 2015Date of Patent: April 20, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Hongfei Wu, Srinath Madasu, Avi Lin

Patent number: 10846463Abstract: 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.Type: GrantFiled: August 29, 2018Date of Patent: November 24, 2020Assignee: Citrix Systems, Inc.Inventors: Hongfei Wu, Yuanyuan Zhang

Patent number: 10790081Abstract: 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.Type: GrantFiled: January 21, 2019Date of Patent: September 29, 2020Assignee: Virginia Tech Intellectual Properties, Inc.Inventors: Chao Fei, Bin Li, Fred C.

Publication number: 20190220182Abstract: 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.Type: ApplicationFiled: January 16, 2018Publication date: July 18, 2019Inventors: Hongfei Wu, Yuanyuan Zhang
