Abstract: A multi-modal communication dynamic switching and adaptive compression system and a method thereof for low-altitude intelligent network are provided. The system includes an airborne terminal and a ground terminal; the airborne terminal comprises a NVIDIA Jetson Xavier NX embedded computing platform, an airborne Raspberry Pi CM4-5G expansion board, an airborne ad hoc network radio, a flight control computer and an optical pod camera; the ground terminal comprises a ground Raspberry Pi CM4-5G expansion board and a ground ad hoc network radio; the multi-modal communication dynamic switching and adaptive compression system and the method thereof for low-altitude intelligent network provided by the invention take advantage of the advantages of longer transmission distance, no dependence on ground infrastructure and flexible deployment of the ad hoc network radio, and use it as a supplementary communication means of 5G public network, so as to ensure the real-time online of UAV.

Abstract: A system and method for allocating a recurring resource is described. The system receives a request to allocate the recurring resource of an application to computing devices associated with one or more users. The system identifies a cadence of the recurring resource and a range based on the cadence. A period is determines based on the cadence and the range. The system accesses user resource data of the application for each period and iteratively computes a resource availability score for the period based on the corresponding user resource data. The system determines that the resource availability score of an instance of the period is less than a threshold value and allocates the recurring resource to instances of the period where the corresponding resource availability score exceeds the threshold value.

Abstract: Systems and methods include determination of a first logical page number of a first database page to be persisted, identification of a first blockmap page associated with the first logical page number, determination, from the first blockmap page, of a block number associated with the first logical page number, determination that the block number is an object key, determination, in response to the determination, that the block number is an object key, determination of a first object key to associate with the first logical page number, and writing of the first database page to the object store using the first object key.

Abstract: Disclosed are a sign-in method and system. The method includes: obtaining, by using a location-based service (LBS) of a mobile terminal, geographical information of a current location of a person who signs in; binding the geographical information of the current location with identity information of the person who signs in and time information, using the geographical information of the current location, the identity information of the person who signs in, and the time information as sign-in information, and sending the sign-in information to a sign-in server; verifying, by the sign-in server, the sent sign-in information; and recording the sign-in information if the verification succeeds. The present disclosure not only can save costs of labor, material, and money, but also can enable several people to sign in simultaneously, thereby greatly improving sign-in efficiency.
