Abstract: A mechanical clutch allows for transfer of torque downhole that may avoid the need for a hydraulic electrical coil-driven piston. In one or more examples, an anti-rotation guide for a downhole clutch includes a guide track and a follower moveable along the guide track for guiding relative movement between an upper armature and a lower armature. The guide track includes an axially-extending portion terminating in a circumferential loop. The axially extending portion guides the upper armature into axial engagement with the lower armature in response to rotation of the input shaft. The circumferential loop thereafter allows rotation of the upper and lower armatures together in response to further rotation of the input shaft.

Display instructions for displaying the visual representation on a client device of the user may be provided to the client device.

Abstract: Systems, methods, and apparatuses for automatically detecting and authorizing recurring transactions are described. Transaction data comprising transaction details for an incoming charge associated with a merchant may be received. Based on the merchant being included in a blocked merchants list, determining that authorization of incoming charges for preauthorized recurring transactions associated with the merchant are blocked. Based on a machine learning model and the transaction data, a probability that the incoming charge for the merchant is a preauthorized recurring transaction may be determined. The machine learning model may be configured to identify preauthorized recurring transactions based on the transaction data. Furthermore, based on the probability not exceeding a threshold probability, the authorization of the incoming charge may be prevented from being blocked.

Abstract: Research work in the literature on imputation of mobility data for missing records of a subject's location trajectory has been specifically revolved around usage of historical data. Thus, performances drop when missing records or imputation mobility data for unknown subject with very little or no historical data has to be predicted. A method and system for training an ensemble classifier for imputation of mobility data of unknown subject based on cohort of the unknown subject is disclosed. The method and system disclosed herein exploits the knowledge that semantic trajectories of different individuals has considerable similarity when individuals belong to the same cohort. This concept is used by the method to predict the behavior of all the individuals in a cohort using ensemble classifier, also referred to as imputation model, trained on the semantic location data of a fraction of total individuals in the cohort with a certain accuracy.
