This invention discloses a multi-agent air-to-ground network resource allocation method based on federated learning. In the air-to-ground network, the ground network constitutes high-data-rate V2I links; the air network constitutes V2U links for direct communication with ground vehicles; the V2U links share the spectrum resources of the V2I links and use hybrid spectrum access technology for transmission; a network resource allocation system model consisting of M pairs of V2I links and K pairs of V2U links is constructed; a multi-agent resource allocation method is adopted, and a deep reinforcement learning model is constructed with the goal of minimizing the total transmission delay of the V2I link channels; federated learning is used to optimize the deep reinforcement learning model; during the execution phase, the V2U links obtain their current state based on observations, and the optimal resource allocation strategy is obtained using the trained model. This invention exhibits good stability in highly dynamic air-to-ground networks.

The method includes: acquiring data to be migrated from a first database; and migrating the data to be migrated from the first database to a second database using a pre-created data migration model, wherein the data migration model is created based on database resources and application resources. This invention can efficiently utilize application resources and database resources.

The invention discloses a Yarn application process tree construction method and device and a storage medium, and relates to the technical field of Hadoop YARN resource management and monitoring. A method for constructing a Yarn application process tree comprises the steps that a monitoring program is started, and a monitor marks monitored application processes as different codes according to configuration; executing corresponding monitoring logic according to the code to obtain an application process tree construction result; the monitoring logic comprises a traditional global scanning construction mode, a single-process mode, a sub-process interface construction mode and an incremental updating mode. The method is simple in implementation mode and suitable for process monitoring and resource metering optimization of the node side of the YARN node-level resource manager, self-adaptive selection for different types of containers is achieved by introducing a multi-mode switchable monitoring framework, and resource waste and performance bottleneck caused by traditional fixed full scanning are avoided.

An intelligent sudoku game machine comprises a chessboard, a board is arranged in the chessboard, a printed circuit board (PCB) is provided with a display screen, the display screen penetrates through the chessboard to be exposed outwards, the PCB is provided with a plurality of light-permeable keys which are arranged in a matrix mode, the keys penetrate through the chessboard to be exposed outwards, and the keys are arranged on the board. A light-emitting element capable of emitting light in various colors is arranged on the PCB in the keys, a control module is further arranged on the PCB, the chess pieces and the induction recognition device are replaced by arranging the light-emitting element and the keys, the product is simple in structure and low in production cost, and the problem that the chess pieces are prone to being lost is solved.

The application relates to the field of cement, and particularly discloses an environment-friendly cement based on carbonaceous coal gangue and a manufacturing method thereof. The environment-friendly cement based on carbonaceous coal gangue raw materials comprise modified coal gangue powder 60-80 parts; cement clinker 30-40 parts; slag powder 10-20 parts; desulfurization gypsum 10-15 parts; tourmaline powder 5-10 parts; ammonium sulfate micro powder 5-10 parts; sodium carboxymethyl cellulose 3-7 parts; and the modified coal gangue powder is obtained by calcining and activating coal gangue powder and then treating the coal gangue powder with a beta-alanine aqueous solution. The environment-friendly cement disclosed by the application takes coal gangue as one of main raw materials, converts the coal gangue into environment-friendly cement with high added value through activation and enhancement treatment. This not only reduces the dependence on natural resources, but also realizes the recycling of waste resources and improves the resource utilization rate; and the cement disclosed by the application can maintain good working performance in the construction process.

This invention discloses an intelligent warehouse racking system, relating to the field of warehouse racking technology. It includes two vertically arranged uprights, with multiple horizontal plates fixed parallel to each other between the uprights. Each horizontal plate has multiple partitions fixed to its top surface, dividing the top surface of the horizontal plate into multiple storage areas for storing goods. Each horizontal plate has a mounting groove corresponding to each storage area, and a conveying component is installed below each horizontal plate at the location corresponding to each mounting groove. Each upright is fixedly mounted with a slide rail and a rack, and slide blocks are slidably mounted on the slide rails. A lifting platform is fixedly mounted on the front side of two slide blocks. This invention features a compact structure and reasonable layout. The partitioned storage method allows for rational and efficient use of all space within the racking system, reducing wasted warehouse space. The racking system automates both the storage and retrieval of goods, resulting in highly efficient operations.
