  • Publication number: 20200211035
    Abstract: Disclosed are methods and systems for generating cure actions for improving a level of user engagement of a network. In some aspects, a method includes identifying network interaction relationships among a plurality of accounts of a computer network based on communication flows among the accounts, and tracking a level of engagement health of each of the accounts based on the interaction relationships over time. For each of the accounts, a determination is made as to whether the tracked level of engagement health meets a threshold requirement. For an account having a level of engagement health not meeting the threshold requirement, a cure action is selected based on one or more rules relating the tracked level of engagement health of the account to one or more predefined criteria. The cure action is then applied to the account.

  • Publication number: 20190334759
    Abstract: Disclosed in some examples are technical solutions to the existing technical problems in computer-implemented identification of anomalous events for distributed unstructured data existing in current supervised and unsupervised approaches. The anomaly detection system may use one or more unsupervised approaches that factor in small data sets using a volume-based time-invariant model. In some examples, in addition, a cross-category proportionality based model may also be utilized.

  • Patent number: 9856702
    Abstract: A cutting element for a cutting tool. The cutting element may be at least partially made from a composite material including a carbide material, a binder material, and a plurality of diamond particles. The carbide material may be from 55 wt % to 97 wt % of a total weight of the composite material. The binder material may be from 3 wt % to 20 wt % of the total weight of the composite material. The plurality of diamond particles may be from 0.1% to 25% of the total weight of the composite material. The carbide material and the binder material may be combined and sintered together prior to being combined with the plurality of diamond particles, such that the carbide material and the binder material form a plurality of pellets having an average cross-sectional length from 10 ?m to 250 ?m.

  • Patent number: 9499888
    Abstract: Carbide pellets including relatively small amounts of metallic binder are produced by steps of pressing, comminuting, shaping and sintering. The carbide pellets may be used as wear resistant hard facing materials that are applied to various types of tools. The carbide pellets provide improved mechanical properties such as hardness and abrasiveness while maintaining required levels of toughness and strength.

  • Publication number: 20150167394
    Abstract: A downhole tool includes a tool body and at least one blade coupled to the tool body. Cutting elements are coupled to a forward surface of the blade, and each cutting element may include a flank face and a trailing face to collectively define the width of the cutting element. A cutting edge is formed at the intersection of the flank face and a front face of the cutting element. The trailing and flank faces of adjacent cutting elements may be inclined relative to each other to define a flank angle that may be between greater than 0° and 15°. Adjacent cutting elements may have a gap therebetween, even when there is contact between the adjacent cutting elements.
