Abstract: A vaporization system and control method are provided. Liquid cryogen is provided to first ambient air vaporizer (AAV) units. When an output superheated vapor temperature is less than a threshold, the liquid cryogen is provided to second AAV units. When greater than or equal to the threshold, it is determined whether the second AAV units are defrosted. When defrosted, the liquid cryogen is provided to the second AAV units. When not defrosted, it is determined whether ice has formed on the first AAV units. When not formed, it is again determined whether the superheated vapor temperature is less than the threshold. When formed, it is determined whether a current ambient condition is favorable to defrosting the second AAV units. When not favorable, the liquid cryogen is provided to the second bank of AAV units. When favorable, it is again determined whether the superheated vapor temperature is less than the threshold.

Abstract: Embodiments provide a voice interaction method and an apparatus, and relate to the field of terminal technologies. Common voice skill commands in a first application scenario may be determined based on the first application scenario and a historical voice skill usage record, and displayed in a display interface. This can implement scenario-based recommendation of voice skill commands, to cover as many application scenarios as possible. In this application, after being woken up, the voice assistant determines the first application scenario based on one or more information items. The voice assistant determines the common voice skill commands in the first application scenario based on the first application scenario and the historical voice skill usage record. The voice assistant displays the common voice skill commands in the first application scenario in the display interface.

Abstract: Embodiments allow, within database security policies, the grant of data change operation-specific privileges to particular users to be applied within particular data realms in a given table. Furthermore, according to one or more embodiments, User Privilege column-level privileges are explicitly associated with one or more data access operations such that the grant of such a column-level privilege allows the user to perform only those data access operations that are explicitly associated with the column-level privilege. Enforcement of the data security policies includes prevention of data leakage via WHERE and RETURNING INTO clauses. According to one or more embodiments, a two-phase rewrite is used to optimize enforcement of column-level privileges. During the two-phase rewrite of a given query, the privileges checked during enforcement of the User Privilege data security policies are pruned to avoid unnecessary privilege checks given the columns that are accessed in the query.
