A vehicle includes a first motor generator that generates electric power using power of an engine, a battery, and a second motor generator that is connected to drive wheels and is driven by electric power supplied from the battery and the first motor generator. An ECU of the vehicle drives the first motor generator as an electric motor with a regenerative electric power, executes a braking control, in which a load of the first motor generator functions as the engine, when an SOC is equal to or more than a threshold value of a waste electric-power start, and changes the threshold of the waste electric-power start based on a running condition of the hybrid vehicle.

An embodiment of the present application provides an image processing method and device thereof, wherein the method includes the following steps: converting the foreground image corresponding to the original image into a compressed image; estimating the first extraction time required for depth feature extraction using the original image and the second extraction time required for depth feature extraction using the compressed image; according to the first extraction time and the second extraction time, it is determined to use the original image for depth feature extraction or use the compressed image for depth feature extraction. By adopting the embodiment of the present application, the calculation amount of the image depth feature extraction process can be effectively reduced, thereby improving the execution time of video object detection.

A power outage plan optimization decision method aiming at reducing power outage time and quantity comprises the following steps: reading the topology information of a distribution network, and establishing the contact relationship between distribution network components in a region to be evaluated to form a contact matrix; reading the information of each load point in the distribution network; reading power outage event information; for each type of power outage events, reading the information of maintenance teams in the region to be evaluated (including the number BN of the maintenance teams in the region to be evaluated, the ability of the maintenance teams and the daily workload of the maintenance teams), and making clear the power outage strategy in the region to be evaluated; optimizing the power outage period; optimizing the power outage order; and displaying the result. The method takes the user's power outage time, the user satisfaction and the team's ability into full consideration, and adopts simultaneous maintenance. For different power outage events, the execution time of each power outage time is optimized based on the daily load curve of an affected region. Thus, the power outage time and power outage quantity of the system are reduced effectively, reliable power supply of the system is ensured, and the customer satisfaction is improved.

An electronic device is provided to enable a user to experience quick launching of applications in the electronic device. The electronic device includes a housing, a display, an input unit, a processor, a non-volatile memory storing an application program, and a volatile memory storing instructions that allow the processor to a state change loads a first portion of the application into the volatile memory, a second state change of the electronic device loads a second portion of the application into the volatile memory, and Displays the image or text resulting from the loaded first and second parts. Since at least a part of the application is preloaded before generating the second input, only the remaining part of the application has to be loaded in order to execute the application after generating the second input.
