Embodiments of the present disclosure provide a method, apparatus, device and storage medium for data processing. If a kernel module sends a data calling request to a userspace process, first modification time information and second modification time information of data corresponding to the data calling request are obtained by the userspace process. The first and second modification time information are used to indicate modification time information of the data in the kernel module and in a file service end, respectively. The first and second modification time information are compared by the userspace process. If the first and second modification time information are inconsistent, a verification invalidation result is returned to the kernel module. The data in the kernel module is invalidated by the kernel module according to the verification invalidation result. The data in the file service is synchronized by the userspace process to the kernel module.

Method, apparatus, device and storage medium for data processing

A data processing method applied to an electronic device is provided. The data processing method includes: establishing, by a first transceiver of a first electronic device; a first wireless connection with a second electronic device; positioning the second electronic device based on the first wireless connection, so as to obtain position information of the second electronic device; adjusting a transmission parameter of a second transceiver of the first electronic device to transmit a second wireless signal, so that the second transceiver transmits the second wireless signal to the second electronic device in a predetermined way; and establishing a second wireless connection with the second electronic device by the first electronic device based on the second wireless signal, a type of the second wireless connection being different from that of the first wireless connection.

Establishing wireless connections with multi-radio device

An apparatus and method for quick imaging and inspection of a moving target. The apparatus comprises a passage, a scanning and imaging device (), a first position sensor (), a second position sensor (), and a control unit (). The control unit () powers on an electron induction accelerator in the scanning and imaging device () to make the electron induction accelerator enter a standby state when the control unit () receives from the first position sensor () a detection signal indicating that a moving target () enters the passage, and controls a beam emitting time point and a beam emitting mode of the electron induction accelerator to correspondingly inspect different parts of the moving target () when the second position sensor () detects that different sections pass through a radiation scanning area. The driver and passengers do not need to get off when a traveling vehicle is inspected, the apparatus controls the accelerator to emit ray beams with corresponding energy to perform scanning when the moving target passes through the scanning area, flexible scanning is realized, and inspection time is reduced.

Apparatus and method for inspecting moving target

The present disclosure provides a control method and an electronic device. The electronic device comprises a first body, a second body and a sensor unit. The first body has a first communication unit, the second body has a second communication unit, the first body and the second body communicate with each other through the first and second communication units. A relative position between the first body and the second body is changeable. The method comprises: detecting a positional relation between the first body and the second body, determining a distance parameter between the first and second communication units based on the positional relation, and adjusting power of each of the first and second communication units based on the distance parameter between the first and second communication units.

Control method and electronic device

Embodiments of the present invention provide a domain name system as well as an information processing method and apparatus of the domain name system. The information processing method includes: receiving a domain name system query request sent by a recursive server, where the domain name system query request includes identifier information of a terminal device that sends the query request; resolving the received domain name system query request to obtain the identifier information of the terminal device; and exercising query control according to the identifier information of the terminal device. In the domain name system as well as the information processing method and apparatus of the domain name system, the domain name system query request carries the identifier information of the terminal device that sends the query request, and therefore, effective control is exercised on the information query actions of the terminal device in the domain name system.

The present invention provides a method and apparatus for generating index as well as a search method and a search apparatus. Index entry comprises at least a search item identifier corresponding to a search item, one or a plurality of index items generated from one or plural pieces of search information, and an accumulator for the search information. The accumulator is generated by accumulating the search information, or accumulating ciphertext of information containing the search information, or accumulating data mapped from information containing the search information. At the time of searching, the index items and the accumulator are provided to a searcher. The searcher extracts search information from the index items and checks whether the extracted search information is complete by using the accumulator. In one embodiment, the accumulator is incorporated in an encrypted inverted index.
