Abstract: A display device includes a blocking dam. The blocking dam includes an insulation layer group. A groove is provided at one side of the insulation layer group away from the substrate. After the liquid organic encapsulation material flows from the display area to the highest point of the blocking dam, the excess liquid organic encapsulation material may directly fall into the groove, avoiding the excess liquid organic encapsulation material from flowing across the blocking dam to the outside of the encapsulation area, causing that the orthographic projection of the edge of the organic encapsulation layer, away from the display area, on the substrate is located within the orthographic projection of the blocking dam on the substrate. The display panel includes only one blocking dam, and the width of the area, where the blocking dam is provided, of the non-display area decreases, thereby reducing the width of the entire non-display area.

Abstract: Using production data and a production flow record based on the production data, a deep neural network (DNN) is trained to model a proxy flow simulation of a reservoir. The proxy flow simulation of the reservoir is performed, using an ensemble Kalman filter (EnKF), based on the trained DNN. The EnKF assimilates new data through updating a current ensemble to obtain history matching by minimizing a difference between a predicted production output from the proxy flow simulation and measured production data from a field. Using the updated current ensemble, a second proxy flow simulation of the reservoir is performed based on the trained DNN. The assimilating and the performing are repeated while new data is available for assimilating. Predicted behavior of the reservoir is determined based on the proxy flow simulation of the reservoir. An indication of the predicted behavior is provided to facilitate production of fluids from the reservoir.

Abstract: Based on a perception of an external environment of an autonomous vehicle, a driving style is recognized according to driving characteristic parameters indicating a driving aggressiveness degree and a mode shift preference, in response to a complexity of an individual driving behavior cognition. After the driving style is recognized, in accordance with group behavior characteristics of the motion bodies in the environment, a time-varying complex dynamical network is established based on a complex network with the motion bodies as nodes and roads as constraints, to serve as a complex environment model of the autonomous vehicle. Finally, the nodes in the complex environment model are parametrically represented to realize the node difference cognition of the complex environment. The nodes in the complex environment model are hierarchized by using an agglomerative algorithm to realize the hierarchical cognition of the complex environment.
