Abstract: Operator actions and/or other commands or requests are secured via an authentication path from an action originator to a communications/control module or any other industrial element/controller. In implementations, an industrial control system includes an action authenticator configured to sign an action request generated by the action originator. The destination communications/control module or any other industrial element/controller is configured to receive the signed action request, verify the authenticity of the signed action request, and perform a requested action when the authenticity of the signed action request is verified.

Abstract: A mechanism for thermal testing is described. A test vehicle includes a heating element, a thermal sensor and a processor. The processor is configured to control the heating element to output an amount of the energy per unit time. Temperature readings are received using the thermal sensor. A thermal property associated with a thermal mass is determined based at least in part the amount of the energy output and the received temperature readings.

Abstract: An online system receives video data items from users and encodes the video data items using various codecs. To account for different computational resources used for encoding using different codecs, the online system ranks combinations of video data items by ratios of encoding video data items with different codecs to computational costs of encoding different video data items with different codecs. The benefit of encoding a video data item with a codec is based on a compression efficiency of the codec and a predicted aggregate amount of the video data item displayed to various users of the online system. Encoding video data items with codecs based on the determined ratios allows the online system to optimize a duration of video data having at least a threshold video quality to users.

Abstract: A different combination of multiple portions of a content item is selected for display to each of multiple sets of users of an online messaging application. The different combination of portions of the content item is sent for display to the corresponding set of users within a user interface of the online messaging application in association with information identifying a set of message threads in which each user is participating. A request to view the entire content of the content item is then received from a subset of each of the sets of users and a performance metric associated with each combination of portions of the content item is tracked based on the received request. Based on the performance metric, a performance of each portion of the content item is evaluated and used to select an optimal combination of the portions of the content item.

Abstract: A ticket exchange server is configured to distribute tickets to an event based on predicted attendance. The ticket exchange server accesses a set of training data describing statistics of and attendance during a historical event for a plurality of historical events. Using the training data, the ticket exchange server trains a machine-learned model, which is configured to predict a likelihood of a seat at a stadium being vacant during an event based on real-time statistics. During an event at the stadium, the ticket exchange server detects a vacant seat associated with a first ticket of a first user. The ticket exchange server determines a value of a second ticket for the vacant seat at least in part by applying the machine-learned model to real-time statistics of the event and distributes the second ticket to a second user.

Abstract: In one embodiment, a method for tensor data distribution using a direct-memory access agent includes generating, by a first controller, source addresses indicating locations in a source memory where portions of a source tensor are stored. A second controller may generate destination addresses indicating locations in a destination memory where portions of a destination tensor are to be stored. The direct-memory access agent receives a source address generated by the first controller and a destination address generated by the second controller and determines a burst size. The direct-memory access agent may issue a read request comprising the source address and the burst size to read tensor data from the source memory and may store the tensor data into an alignment buffer. The direct-memory access agent then issues a write request comprising the destination address and the burst size to write data from the alignment buffer into the destination memory.

Abstract: When a user creates a new video exchange session via an online system, the user specifies an activity for the video exchange session. The activity may specify a name for the video exchange session, as well as other thematic content (e.g., visual effects, backgrounds) displayed via the video exchange session. The online system trains a machine learned model that predicts a likelihood that other users will accept an invitation to join the video exchange session if a certain activity is specified for the video exchange session. The online system may then use these likelihoods to rank and sort the activities for the user or to highlight activities with threshold likelihoods.
