Abstract: Techniques are disclosed relating to automatically altering a displayed user interface for an event. A server computer system may cause, via a conferencing service, display of a user interface for an event having a group of users accessing the conferencing service via a plurality of user devices, the displayed interface including an indication of a video feed of a user in the group of users that is currently active. The system may store, in a database, data for the event, including content of audio and video feeds of users in the event. The system may analyze a set of characteristics included in the content of the audio and video feeds. The system may alter, while the indication of the video feed of the user is being displayed, aspects of the displayed user interface other than the indication, where the altering is performed based on the analyzing.

Abstract: Techniques are disclosed for automatically executing scripts for event in response to user activity within the event. A server executing a video conferencing service, receives meeting scheduling information and a set of user-specified scripting information from a user requesting to generate an event. In response to receiving a request from user device to access the event, the server causes display of an event interface to the device, the displayed interface including indications of sub-groups of a group of users accessing the conferencing service via a plurality of user devices and an indication of a video feed of a user in the group of users that is currently active. In response to one or more triggers corresponding to the event, one or more scripts are executed for the event, where executing the one or more scripts includes altering the displayed interface.

Abstract: Technologies are generally described for holding an impeller of a pump assembly in place axially with an impeller locking collar by loading the collar against a ring element. In a centrifugal pump assembly, one side of the shaft has a larger diameter for the impeller to abut against. The other side of the shaft may be fitted with an impeller locking collar comprising two portions that can be threaded together and hold the impeller in place by tightening against a ring element such as a split ring or spiral lock. Anti-rotation to avoid loosening of the impeller locking collar may be achieved by providing counter threads against a shaft rotation. Secondary anti-rotation may be provided by one or more set screws in the impeller locking collar.

Abstract: Methods, systems, and devices for automated feature selection and model generation are described. A device (e.g., a server, user device, database, etc.) may perform model generation for an underlying dataset and a specified outcome variable. The device may determine relevance measurements (e.g., stump R-squared values) for a set of identified features of the dataset and can reduce the set of features based on these relevance measurements (e.g., according to a double-box procedure). Using this reduced set of features, the device may perform a least absolute shrinkage and selection operator (LASSO) regression procedure to sort the features. The device may then determine a set of nested linear models—where each successive model of the set includes an additional feature of the sorted features—and may select a “best” linear model for model generation based on this set of models and a model quality criterion (e.g., an Akaike information criterion (AIC)).

Abstract: Rotating equipment includes driver equipment, driven equipment and a rotating shaft coupling. The driver equipment includes a driver support connected to a stationary driver shaft, and also includes a driver arranged on the driver support with a driving shaft to rotate and provide a rotational torque. The driven equipment includes a driven unit support connected to a stationary driven unit shaft, and also includes a driven unit arranged on the driven unit support with a driven shaft to respond to the rotational torque and rotate. The rotating shaft coupling couples the driving shaft to the driven shaft and applies the rotational torque from the driving shaft to the driven shaft. The stationary driver shaft couples to the stationary driven unit shaft to provide a static torque load to counteract the rotational torque applied from the driving shaft to the driven shaft during operation.

Abstract: Technologies are described for devices and methods for adjusting a position of impellers within a bowl assembly. The devices may comprise an adjuster at the second end of a spacer coupling. The adjuster may include an adjuster sleeve. The adjuster sleeve may be a cylindrical sleeve. The adjuster sleeve may be threaded on an internal side.

The adjuster sleeve may threadedly mate and engage with an externally threaded first end of the driven shaft when the adjuster sleeve is rotated. The rotation of the adjuster sleeve may adjust a position of the driven shaft with respect to the driven hub and may thereby adjust a position of an impeller attached to a second end of the driven shaft with respect to a stationary bowl.

Abstract: A binary outcome of an activity is predicted based on samples of the activity. The activity is characterized by features that can take on any of a set of mutually exclusive levels. An initial candidate pool of terms is selected. The terms are feature levels or combinations of feature levels. The candidate terms are used to create two ordered pools of terms, one including terms that are positively predictive and another including terms that are negatively predictive. The terms in each pool are ordered by strength of predictiveness and diversity of predictiveness relative to terms higher in the order. A final set of terms is selected by combining terms from these two pools.
