Abstract: The present disclosure provides a communicating method for vehicle users, a communicating system for vehicle users, and a computer-readable storage medium. The communicating method includes following steps: establishing a communicating area with respect to the vehicle, and defining a coordinate range of the communicating area; connecting at least one user terminal, and acquiring a personal coordinate from each of the user terminals; and responding to the personal coordinates of user terminals being located in the coordinate range of the communicating area at the same time, to establish information correlation for each user terminal located in the communicating area.

Abstract: Embodiments of the present disclosure provide a method, a device and a computer program product for managing data replication. According to example implementations of the present disclosure, a replication policy model associated with data replication of a source device can be obtained, which is determined based on historical status information of the source device and a historical replication policy corresponding to the historical status information; current status information of the source device is determined, wherein the current status information indicates status information associated with pending data replication of the source device; and a target replication policy is determined based on the replication policy model and the current status information, which indicates a replication policy to be applied for performing the pending data replication.

Abstract: Embodiments of the present disclosure provide methods, apparatus, and computer storage media for application error diagnosis. The method of application error diagnosis may include obtaining information related to an error in an application, generating a code of the information related to the error in the application, determining a similarity between the code and at least one predetermined code, wherein the at least one predetermined code is being associated with a known software bug. The method further includes determining at least one software bug related to the error in the application by comparing the similarity with a predetermined threshold.

Abstract: An audio communication system, an audio transmitter and an audio receiver are described herein. In one aspect, the audio transmitter includes: An analog to digital converter configured to convert an analog audio signal into a digital audio signal; a digital compressor configured to compress the dynamic range of said digital audio signal; a digital modulator configured to modulate the compressed digital audio signal into a wireless communication signal; and the analog to digital converter, the digital compressor and the digital modulator are integrated in one integrated circuit. The described devices improve the compression and expansion device linearity, resulting in better match for the compressor at the transmitter and the expandor at the receiver.
