摘要： A casino table poker game where all cards are dealt face-up and the dealer plays a hand. Players each place an ante wager and are initially dealt a partial face-up poker hand and the dealer is dealt a complete face-up poker hand. If the dealer's poker hand meets or exceeds a kick out threshold, the dealer folds her poker hand. The kick out threshold can vary based on the number of players in the game. Then, from lowest to highest rank of partial face-up poker hands, players can fold or pay an additional wager to receive additional cards to complete their face-up poker hand. The pot is awarded to the dealer or player with the best poker hand according to a predetermined set of poker game rules.

摘要： In methods and systems that may facilitate detecting abnormal operation in a process plant, values of a process variable are analyzed to determine whether they significantly deviate from expected values. If there is a significant deviation, an indicator may be generated. Analyzing the process variable may include, for example, utilizing a plurality of thresholds determined based on statistics of the process variable. Analyzing the process variable may also include, for example, determining whether a first number of values of the process variable are in a first region, and whether a second number of values are in a second region.

摘要： A system and method for detecting abnormal operation of a hydrocracker includes a model to model the hydrocracker. The model may be configurable to include one or more regression models corresponding to different operating regions of the portion of the hydrocracker. The system and method may also determine if a monitored temperature difference variable deviates significantly from the temperature difference variable predicted by the model. If there is a significant deviation, this may indicate an abnormal operation.
