Abstract: A method for lifting a subway shield tunnel by polymer grouting includes steps of: detecting settlement of the shield tunnel, and determining a settlement location, a settlement range and a settlement amount; drilling a row of isolation barrier holes on both sides of a settlement repair area, and injecting quick-setting slurry so that two isolation barriers are formed; drilling grouting channel holes from ground, and then drilling horizontal grouting holes below the settlement; connecting grouting pipes to geotextile bags, and feeding the geotextile bags into each of the grouting holes in turn; using a polymer grouting system to inject polymer slurry into the geotextile bags, wherein the polymer slurry then expands to lift up a soil layer above and jack up a tunnel structure; and after lifting, filling and sealing the grouting channel holes. The method is efficient and convenient without the need for maintenance.

Abstract: A computer-implemented method for performing a document search action includes receiving a search request identifying a sample document. A plurality of terms occurring within the sample document is identified. Each term is scored based on a global term frequency of that term within a collection of documents. Each term is then weight based on proximity, within the sample document, of that term to at least one of the other terms of the first plurality of terms. A document search query is created to include a proximity-limiting clause restricting results to include documents that have a highest-weighted term of the first plurality of terms within a threshold distance of another term of the first plurality of terms. The document search query is performed, thereby resulting in identification of a first resulting document.

Abstract: An offshore floating-type wind power combined semi-submersible platform foundation has at least three stand columns that form an enclosure having a polygonal structure. The adjacent stand columns are connected by an upper support and a lower support. Each stand column is composed of an upper column body and a lower column body that are arranged coaxially. An upper portion of the upper column body is provided with a support block, the upper support rests on the support block. A lower portion of the upper column body is provided with a lower support connecting portion that is connected to the lower support. With the structural form of the offshore floating-type wind power combined semi-submersible platform foundation, the requirements for a manufacturing site and a combination site are greatly reduced, providing the possibility of large-scale offsite construction.

Abstract: Techniques have been developed to facilitate the capture of performances on handheld or other portable computing devices and, in some cases, the pitch-correction and mixing of such vocal performances with backing tracks for audible rendering on such devices. Captivating visual animations and/or facilities for listener comment and ranking are provided in association with an audible rendering of a performance, e.g., a vocal performance captured and pitch-corrected at another similarly configured mobile device and mixed with backing instrumentals and/or vocals. Geocoding of captured vocal performances and/or listener feedback may facilitate animations or display artifacts in ways that are suggestive of a performance or endorsement emanating from a particular geographic locale on a user manipulable globe. In this way, implementations of the described functionality can transform otherwise mundane mobile devices into social instruments that foster a unique sense of global connectivity and community.

Abstract: A CT apparatus in which the x-ray source is coupled to a source robotic arm and the detector is coupled to a detector robotic arm. A motion correction module utilizes a locally linear embedding motion correction algorithm to estimate the geometry-describing parameters associated with the positions of the source and detector and the angle of the detector. These estimates are used to reconstruct the image data and produce corrected images with fewer errors resulting from patient movement, misalignments, and coordination issues in the system.
