Abstract: An electronic device is provided, including a display panel and a processor. The display panel is configured to display image data and includes a backlight module, and the processor is electrically connected to the display panel. The processor averages current values of the backlight module corresponding to the image data in a first time period, to generate an average current value, and compares the average current value with a current threshold. When the average current value is greater than the current threshold, the processor generates an adjusted maximum current value, and correspondingly reduces current values of the backlight module in a second time period according to the adjusted maximum current value, to reduce a temperature of the electronic device. A temperature adjustment method of an electronic device is also provided.

Abstract: A computer-implemented system and related method address malfunctioning peers in a blockchain, the method comprising receiving endorsement results from peers in the blockchain, where the endorsement results are for one or more transactions in the blockchain. The endorsement results include successful and failed endorsements. The method further comprises distributing the successful and failed endorsements to two or more endorsement collectors, determining which peers are successful endorsement peers (SEPs) that provided successful endorsements, and which peers are failed endorsement peers (FEPs) that provided failed endorsements. A reputation score is calculated for each peer based on endorsement information from the endorsement collectors. The reputation score is then sent to at least one of a client and a system administrator. This reputation score is then used to determine peer selection in a subsequent transaction.

Abstract: Techniques include generating a log sequence for new logs that have been received, searching a log sequence database for the log sequence having been generated, and determining that the log sequence is anomalous in response to not finding an identical log sequence in the log sequence database. In response to the log sequence not being found in the log sequence database, the log sequence is compared to a graph of historical log sequences to find a closest sequence path to one or more historical log sequences. An anomaly of the log sequence is diagnosed based on an occurrence at which the log sequence deviates from the closest sequence path of the one or more historical log sequences.
