The invention discloses a database access method and device for preventing user data leakage in a container, and the method comprises the steps: a business service sends a connection establishment request to a database service; a database side vehicle service hijack connection establishment request which has the same POD with the business service and is different from the business service in a container contai ner; the database side vehicle service analyzes a database protocol, modifies a user name and a password in the connection establishment request, and forwards the modified connection establishment request to the database service; the database service performs user name and password verification based on the modified connection establishment request, and returns a response after the verification is passed; and the database side vehicle service receives the response of the database service and forwards the response back to the business service, and the business service establishes database connection with the database service. According to the invention, the database side vehicle service is introduced between the business service and the database service, all database connection requests are intercepted, and the business service does not need to know the user name and password of the database when connecting the database, so that the leakage of certificates is avoided.

The present application belongs to the technical field of networked converter control, and discloses a networked converter control method, system, device and medium based on network side information feedback to solve the problem of subsynchronous oscillation. The method comprises: collecting voltage signals of a grid side point of common connection and voltage signals and current signals of a converter side; calculating steady-state active power and steady-state reactive power based on the voltage signals of the grid side point of common connection and line impedance parameters; calculating transient active power and transient reactive power based on the voltage signals and current signals of the converter side; introducing a composite factor to fuse the steady-state active power and the transient active power to obtain composite active and reactive power; and inputting the composite active and reactive power to a power outer loop controller of the networked converter to generate a reference signal for inner loop control. The present application improves system damping and the ability to suppress subsynchronous oscillation.

This application relates to a method, apparatus, device, and storage medium for short-time audio speaker recognition. The method includes: acquiring speech features of all speech frames in a short-time audio stream, filtering all speech features to generate an effective speech feature map; sequentially fusing the effective speech feature map with local features from different frequency bands several times to obtain local fused features for different frequency bands; performing staged global fusion based on the local fused features of each frequency band except for the low-frequency band to obtain a global fused feature; inferring a speech vector based on the global fused feature, and comparing the speech vector with a registered vector in a registered sound database to identify the speaker's identity. This method improves the accuracy of short-time audio speaker recognition without compromising the core architecture of the model, while maintaining lightweight design and deployment compatibility.

The invention provides an encryption method and device for reserving an original format of Chinese character type data and electronic equipment, and relates to the technical field of data encryption, and the method comprises the following steps: firstly, carrying out random coding on original data which is Chinese character type data including sensitive information to generate coded digits, and then carrying out symmetric encryption on the coded digits to generate coded digits; generating a coded encrypted digit; and decoding the coded encrypted digits to generate encrypted target data, and the format of the target data is the same as that of the original data. Through the method, the technical problem of keeping the original format unchanged during Chinese character type data encryption can be solved, and the technical effects of giving consideration to information security and keeping data consistency and compatibility are achieved.

This invention provides a quantum cascade laser and its fabrication method. The quantum cascade laser includes an active layer, which comprises multiple first sub-active layer units to the Mth sub-active layer units stacked sequentially in a first direction, where M is an integer greater than or equal to 2. Any mth sub-active layer unit includes W lower mth sub-active layers and W upper mth sub-active layers, with the lower mth sub-active layers and upper mth sub-active layers stacked alternately in the first direction, where m is an integer greater than or equal to 1 and less than or equal to M, and W is an integer greater than or equal to 2. Any mth sub-active layer unit with alternating stacked Q... m1 The m-th sub-active layer and Q m2 The m-th active layer contains doped ions; where Q m1 Q is an integer greater than or equal to 1 and less than W. m2 It is an integer greater than or equal to 1 and less than W; the doping concentration of the doped ion first increases and then decreases as the value of m increases.

In the present invention, a user equipment (UE) receives an UL grant that can be used while the UE is not in RRC_CONNECTED state. If the UE receives a message indicating to leave RRC_CONNECTED state, the UE starts a time alignment timer (I-TAT) when the UE leaves RRC_CONNECTED state. The UE transmits UL data using the UL grant if the UL data becomes available for transmission when the UE is not in RRC_CONNECTED state and if the I-TAT is running.
