Abstract: A wiper dart can be used in an oil and gas operation. The wiper dart can have at least two different outer diameters. A first outer diameter can be less than a second outer diameter and used to wipe the insides of tool joints of a tubing string. The second outer diameter can be used to wipe the insides of pipe sections of the tubing string that have a larger inner diameter than the tool joints. The single, bi-diameter wiper cup can be used in lieu of two or more current, conical-shaped wiper cups to accomplish the same functionality. The wiper cup can be generally bell shaped and have a variety of first and second outer diameters.

Abstract: An access service is positioned between a set of container groups and a SQL database service. Upon receipt, at the access service, of a REST request from any container group indicating that a SQL transaction should be started, an entry is created in a staging database, separate from the SQL database service, to track the SQL transaction. Multiple connections are allowed to be established from the container groups to the access service over which other REST requests from any container group are sent. The other REST requests include details of SQL operations to be performed as part of the SQL transaction. The details are cached in the staging database. Upon receiving a REST request from any container group indicating that the SQL transaction should be committed, a single connection is established between the access service and SQL database service to commit the transaction, including the details, as an atomic transaction.

Abstract: Methods and systems are described herein for a component allocation system for temporarily allocating components via resource tokens. The component allocation system may receive a request for components that match a set of user-defined criteria. The component allocation system can determine, based on the set of user-defined criteria, components that satisfy the set of user-defined criteria. Responsive to receiving a user selection of a first and second component from the determined components, the system may input component data for each of the first and second components into a machine learning model, where the machine learning model is trained to determine whether two components are interchangeable. Responsive to obtaining the indication that the first and second component are interchangeable, the system may generate a resource token indicating temporary transfer of the first and second component to a user.

Abstract: Logic may provide a hierarchical label structure for a document with a predicted set of hierarchical labels. Logic may provide a historical label performance database comprising performance data associated with each assignee in a complete set of assignees for each label in a complete set of the hierarchical labels. Logic may generate a first vector for the hierarchical label structure for the document. Logic may generate a second vector for the assignees in an identified set of assignees, comprising each hierarchical label in the predicted set of hierarchical labels for the document, the identified set comprising one or more of the assignees in the complete set of assignees. Logic may perform a similarity search to identify a predicted assignee from the identified set of assignees and logic may predict a selected assignee of the identified set of assignees to associate with the document via the similarity search.

Abstract: The present disclosure describes an artificial intelligence approach to digital content recommendation where the recommendation mechanics differ based on the amount of information available. In one aspect, a user is identified as an above-threshold user who has consumed at least a threshold number of digital artifacts or a below-threshold user who has consumed fewer digital artifacts and different recommendation engines are used for above-threshold users and below-threshold users. In another aspect, users are bifurcated into low-data users and high-data users. For high-data users, digital artifacts are directly selected, and for low-data users, digital artifacts are indirectly selected by first selecting a digital artifact property criteria and then selecting digital artifacts that satisfy the selected digital artifact property criteria.

Abstract: An electronic wall map design and printing system enables a user to select or specify the size, coverage area and detail level of a wall map and to customize the wall map based on the user's needs via a fully automated electronic interface. For ease of viewing during the creation of the wall map, the design and printing system displays the wall map being designed on the electronic user interface at a first detail level or resolution that is less than the level of detail or resolution used to print the wall map. However, the user may use the electronic interface to view portions of the wall map on the user interface at the same level of detail to be actually printed on the wall map to thereby enable the user to assure that the level of detail to be printed on the wall map is adequate for the user's purposes without making the wall map, as printed, hard to read. Once the user has designed the wall map by selecting the size, coverage area, and other customizable features such as titles, specialized icons, etc.
