A filter element for coupling adsorption and regeneration of volatile organic compounds and a purification device are provided. The filter element includes a filter element body, a photocatalytic mechanism and adsorption-filtration body(s). The adsorption-filtration body(s) may be of a hollow columnar structure where the photocatalytic mechanism is located. VOCs are quickly adsorbed by the adsorption-filtration body(s), then thermal desorption regeneration is performed on the adsorption-filtration body(s) during a time interval of stopping discharging of the exhaust gas, and a photocatalysis technology is used to cyclically purify the thermally desorbed VOCs, which achieves the synergy of high-density and purification in the two technologies. Furthermore, it takes full advantages of high adsorption, filtration and purification efficiency, low photolysis catalysis costs, and easy operation and maintenance of the on-site regeneration.

Embodiments of the present disclosure relate to a method and apparatus for recognizing a table, a device, and a medium. An embodiment of the method can include: detecting a table on a target picture, to obtain a candidate table recognition result; extracting a merging feature of the candidate table recognition result, and determining a to-be-merged row in the candidate table recognition result based on the merging feature; extracting a direction feature of the to-be-merged row, and determining a merging direction of the to-be-merged row based on the direction feature; and adjusting the candidate table recognition result based on the to-be-merged row and the merging direction of the to-be-merged row, to obtain a target table recognition result.

Method and apparatus for recognizing table, device, medium

A method, apparatus, electronic device, storage medium and program product of code management are provided. In response to a request for building an executable file, corresponding developed code is obtained from a code library. The developed code is compiled into intermediate code to determine security of the intermediate code. In response to determining that the intermediate code is secure, an executable file is generated based on the intermediate code.

Method, apparatus for managing recommendation policy

In some embodiments, a method includes: obtaining position information of a wireless hotspot where the user locates, based on hotspot scanning information of wireless hotspots already scanned by the user; acquiring one or more candidate Points of Interest (POIs) close to the wireless hotspot based on the position information; based on characteristic information corresponding to the wireless hotspot and respective candidate POIs, ranking all candidate POIs to determine an POI matching the wireless hotspot, wherein the characteristic information comprises access characteristic information. In some embodiments, the following advantages may be realized: the POI matching the wireless hotspot is obtained based on relevant data that the user scans the wireless hotspot to predict the POI actually accessed by the user without a procedure of manually collecting the data or user feedback, thereby improving the efficiency.

Method and apparatus for matching wireless hotspot with POI

A method and apparatus are for determining a location of a new point of interest by determining demand information of a user based on retrieval data of the user. The retrieval data includes at least point of interest data, and the demand information includes at least a demand occurrence position. Supply information, including at least a supply region of existing points of interest are obtained based on the retrieval data. The demand information of the user is matched with the supply information of the existing points of interest to obtain the unsatisfied demand information of the user. The location of the new point of interest is determined based on the unsatisfied demand information of the user. The demand information for determining the location of a new point of interest is more accurate and comprehensive, and accuracy and reliability of the site selection of a new point of interest are improved.

Method and apparatus for determining a location of a point of interest

A method, computer program product and computer system is provided. A processor receives a read request for a data entry from a client device, where the read request includes a first identifier. A processor retrieves a second identifier from a first storage device, where the second identifier is associated with the data entry as stored in the first storage device. Responsive to the first identifier and the second identifier not matching, a processor updates the data entry of the first storage device with a corresponding data entry from a second storage device.

Data consistency maintenance for sequential requests

A data processing method, data query method in a database, and corresponding device. A data processing, wherein a query request for data records includes information indicating a source and destination IP address, the source IP address including N sections, the destination IP address including M sections, both M and N being positive integers, the method including: determining an index encoding manner for the database, wherein the index is an one-dimensional index including N+M sections, the encoding manner specifying a variation sequence of various sections for the index, at least one of the source IP address and the destination address indicated by the information contained in the possible query request including at least one section having a wildcard character, wherein according to the index, for any possible query requests, successive data records can be obtained as a query result; according to the encoding manner, establishing the index for the data records.
