Abstract: An advanced nitrogen removal method using partial nitrification-denitrification coupled two-stage autotrophic denitrification. Sewage is introduced into a first pool for partial nitrification-denitrification treatment, and then introduced into a first regulating reservoir. Dissolved oxygen content in the first pool is kept at 0.4-0.6 mg/L. Water is discharged when a molar ratio of nitrite nitrogen to ammonia nitrogen in the first regulating reservoir is 1.0-1.3:1. Effluent in the regulating reservoir is introduced into a second pool for anaerobic ammonia oxidation treatment, and then introduced into a second regulating reservoir. In the second pool, pH is 7.0-7.4, a temperature is 22-28° C. Effluent in the second regulating reservoir and sulfides are introduced into a third pool for denitrification treatment. Water is discharged. In the third pool, pH is 7.5-8.0, a temperature is 28-32° C., a mass ratio of sulfur to nitrogen is 1.9-2.0:1.

Abstract: The present disclosure provides a storage control method, a storage controller, a storage device, and a storage system. The storage control method controls a storage behavior of a storage device, including: acquiring behavior information of the storage device; processing the behavior information through a deep learning algorithm to obtain a behavior parameter of the storage device; and adjusting an operation mode of the storage device according to the behavior parameter of the storage device. The present disclosure enhances the automatic adjustment operation algorithm of the storage device by means of deep self-learning to adapt to the different requirements of the complex system for the storage device, thereby achieving the storage device with the optimal read/write performance, the best reliability, and the lowest power consumption in accordance with the requirements of the system.

Abstract: The invention discloses a multi-human tracking system and method with single Kinect for supporting mobile virtual reality applications. The system can complete the real-time tracking of users occluded in different degrees with a single Kinect capture device to ensure smooth and immersive experience of players. The method utilizes the principle that the user's shadow is not occluded when the user is occluded under certain lighting conditions, and converts the calculation of the motion of the occluded user into a problem of solving the movement of the user's shadow, and can accurately detect the position of each user, rather than just predicting the user's position, thereby actually realizing tracking.
