Abstract: A solution is disclosed for memory management of serverless databases that includes: based at least on detecting a trigger event, determining whether memory is to be reclaimed; based at least on determining that memory is to be reclaimed, determining an amount of memory to be reclaimed; identifying memory to be reclaimed; and reclaiming the identified memory. Disclosed solutions are flexible, enabling customization of the aggressiveness and manner of memory reclamation. This permits users to specify a tailored balance point between performance and cost, for arrangements that bill users based on resource usage (e.g., memory consumed by a serverless database). In some examples, users specify a ramp-down parameter that is used to determine how much memory can be evicted in a particular reclamation event, time intervals (or another criteria) for triggering a reclamation event, and a definition for whether a cache is active.

For example, information for different users may be mapped to different Polar code sub-channels. In some aspects, the mapping may be unbalanced in that different information is mapped to different sub-channels according to the quality (e.g., in terms of error probability) of the sub-channels and a criterion associated with the information. For example, control information for users that are experiencing the worst channel quality (e.g., in a wireless communication channel) may be mapped to the Polar code sub-channels that have the best quality.

Abstract: A method for relieving vaulted expansion of a cement-stabilized base layer through precut seams. The method firstly establishes an RBFN model according to a large number of observation results of a vaulted expansion amount of the cement-stabilized base layer under different conditions (such as temperature and a stress release structure) in Xinjiang and similar regions; and on such a basis, the vaulted expansion amount of the cement-stabilized base layer to be designed is predicted. When the vaulted expansion amount is greater than a control requirement, the RBFN model is configured to design a reasonable width and a reasonable interval of the precut wide expansion seams to ensure that the vaulted expansion amount of the cement-stabilized base layer is less than a control value. Based on the design of the RBFN model, the present invention provides a corresponding construction method for the precut wide expansion seams.
