Abstract: Innovations in adaptive encoding of screen content based on motion type are described. For example, a video encoder system receives a current picture of a video sequence. The video encoder system determines a current motion type for the video sequence and, based at least in part on the current motion type, sets one or more encoding parameters. Then, the video encoder system encodes the current picture according to the encoding parameter(s). The innovations can be used in real-time encoding scenarios when encoding screen content for a screen sharing application, desktop conferencing application, or other application. In some cases, the innovations allow a video encoder system to adapt compression to different characteristics of screen content at different times within the same video sequence.

Abstract: A well cementing method is described for improving cementing quality by controlling the hydration heat of cement slurry. By controlling the degree and/or rate of hydration heat release from cement slurry, the method improves the hydration heat release during formation of cement with curing of cement slurry, improves the binding quality between the cement and the interfaces, and in turn improves the cementing quality at the open hole section and/or the overlap section. The cementing method improves cementing quality of oil and gas wells and reduces the risk of annular pressure.

Abstract: Some embodiments provide a method of identifying packet latency in a software defined datacenter (SDDC) that includes a network and multiple host computers executing multiple machines. At a first host computer, the method identifies and stores (i) multiple time values associated with several packet processing operations performed on a particular packet sent by a first machine executing on the first host computer, and (ii) a time value associated with packet transmission through the SDDC network from the first host computer to a second host computer that is a destination of the particular packet. The method provides the stored time values to a set of one or more controllers to process to identify multiple latencies experienced by multiple packets processed in the SDDC.

Abstract: A control method is in use of an interleaved power converter with first and second power stages for generating an output power source. A compensation is generated in response to a feedback signal and a reference voltage, and the feedback signal represents the output power source. The output power of the first power stage is controlled to supply to the output power source in response to the compensation signal. The operation status of the second power stage is switched in response to the compensation signal and the feedback signal, and is prevented from being switched when the feedback signal is beyond a stable range covering the reference voltage.

Abstract: The subject technology provides a video conferencing application in which a live incoming or outgoing video stream can be supplemented with supplemental content, such as stickers, animations, etc., from within the video conferencing application. In this manner, a user participating in a video conferencing session with a remote user can add stickers, animations, and/or adaptive content to an outgoing video stream being captured by the device of the user, or to an incoming video stream from the device of the remote user, without having to locally cache/store a video clip before editing, and without having to leave the video conferencing session (or the video conferencing application) to access a video editing application.

Abstract: A method, a computer program product, and a computer system compare images for content consistency. The method includes receiving a first image including a first document and a second image including a second document. The method includes performing a visual classification analysis on the first image and the second image. The visual classification analysis generates an overlap of the first image with the second image. The method includes determining whether a region of the overlap is indicative of a content inconsistency. As a result of the region of the overlap being indicative of a content inconsistency, the method includes performing a character recognition analysis on a first area of the first image and a second area of the second image corresponding to the region of the overlap to verify the content inconsistency.

Abstract: This disclosure includes back pattern counter measures for solid state drives. Embodiments described herein include setting and applying read threshold offsets according to flags set based on an amount of data stored within a memory block (e.g., an “openness” of the block). The flag is implemented during read commands to account for shifts in voltage distribution of open blocks. A value of the flag may be chosen based on a number of word lines included in the block that store data. The read threshold offsets may further be based on at least one of the set flag or an age of a respective NAND cell.

Abstract: Concepts of using optimization-based policy in reinforcement learning (RL) are described. In one example, a method can include implementing an RL agent in a subsystem of the sequential decision-making system.

The method can also include learning a policy that is defined by the optimization module based on the parameter value and a predicted future state of the subsystem that is predicted by the prediction module based on the reward. The policy can include a suggested action to be performed by the subsystem to achieve a goal. The method can also include implementing the policy to perform the suggested action.
