Abstract: The present disclosure relates to systems for identifying instances of natural language input, determining intent classifications associated with instances of natural language input, and generating responses based on the determined intent classifications. In particular, the disclosed systems intelligently identify and group instances of natural language input based on characteristics of the user input. Additionally, the disclosed systems determine intent classifications for the instances of natural language input based message queuing in order to delay responses to the user input in ways that increase accuracy of the responses, while retaining a conversational aspect of the ongoing chat. Moreover, in one or more embodiments, the disclosed systems generate responses utilizing natural language.

Abstract: Request-driven file pulling from unsynchronized directories is described. Rather than maintaining entire files, a service provider merely maintains file tags which describe the files in unsynchronized directories of devices associated with a user and communicates the file tags to the devices. The file tags enable indications of the files to be presented so that selected files can be pulled from the unsynchronized directories. Based on user selections made at a first of the devices to pull files from a second of the devices, requests are communicated from the first device to the service provider for the selected files. Responsive to a request, the service provider communicates an indication to the second device to copy the selected file from the second device's unsynchronized directory to a synchronized directory. Responsive to this, the service provider obtains the file from the synchronized directory and delivers the file to the first device.

Abstract: A device for the placement of material on a surface includes a housing, a motor coupled to the housing, and a driving component coupled to the housing and powered by the motor. The device further includes at least one guide chute defining a guide channel with the driving component. The device further includes a layup roller coupled to the housing adjacent the guide channel. The layup roller includes a roller surface and the guide channel is configured to discharge a quantity of material to the roller surface. The layup roller is configured to deposit the material onto the surface.

Abstract: A method includes automatically creating one or more test schedules for a well test of one or more wells in an oil or gas production environment. The method also includes automatically creating one or more test frames for use in generation of the well test. The method further includes, following execution of the test frame, automatically validating one or more test records generated during the one or more test frames. In addition, the method includes automatically creating the well test for determining one or more well characteristics.

Abstract: Methods for forming ceramic matrix composite (CMC) components are provided. In one exemplary embodiment, a method comprises automatically laying up CMC plies. Laying up plies includes transferring a CMC ply to a layup tool; applying heat to the CMC ply; and stacking the CMC ply with at least one other CMC ply. In various embodiments, CMC plies may be laid up using an automated machine. In some embodiments, a CMC ply may be transferred to a layup tool using an automated machine and the CMC ply may be stacked with at least one other CMC ply using the automated machine.

Abstract: A method for shaping a ceramic matrix composite (CMC) sheet having a first surface and a second surface is presented. The method includes receiving an input signal representative of a predetermined shape and a type of the CMC sheet. Further, the method includes selecting a laser beam based on the received input signal. Also, the method includes projecting the selected laser beam on the CMC sheet to shape the CMC sheet into the predetermined shape.

Abstract: A data storage system has a plurality of hosts that request writes of data to a relatively high-performance storage device (RHPSD) such as NVRAM, which may be one of a plurality of RHPSDs in a plurality of storage nodes. A storage management system receives the write requests and writes received data to the RHPSD. According to an allocation policy, the storage management system indicates to at least one of the hosts that it should limit its use of RHPSD and it then discards data upon indication from that host to do so. Before being discarded from the RHPSD, the data may be written to a persistent storage device.

Abstract: An indication is received that a data object is to be deleted, wherein the data object comprises data stored in a segment within a container. It is determined no currently alive data object references any segment within the container. The container is placed in a delete-ready but not yet reclaimable state.

Abstract: In one embodiment, in response to a request received from a client for retrieving a data object stored in a storage system, a root key is obtained from the request. The data object is represented by metadata in a hierarchical structure having a plurality of levels. Each level includes a plurality of nodes and each node being one of a root node, a leaf node and an intermediate node. The hierarchical structure of metadata associated with the data object is traversed in a top-down approach to decrypt each of a plurality of nodes in the hierarchical structure using a key provided from its parent node, starting from the root node to the leaf nodes, including decrypting the root node using the root key. Decrypted data associated with the plurality of nodes is transmitted to the client.
