Abstract: Disclosed is a hybrid refrigeration full fresh air-conditioning unit, which achieves multistage cooling by means of the combination of a surface cooler cooling system, a refrigerant air-conditioning system and a direct expansion type air-conditioning system. The unit has an outdoor side mainly for cool water supply to a cooler (115) and conducting heat dissipation on a condenser (212) and an indoor side mainly for conducting multistage treatment of air entering a room. The indoor side and the outdoor side are connected to form a whole and are isolated via a panel. The refrigerant air-conditioning system cooperates with one or two of the other systems. Each system can independently operate or simultaneously operate together so that temperature and humidity control for all-weather can be provided, and their operation can be conducted in the most economical and environmental friendly manner under different temperature and humidity condition.

Abstract: In the method and system for knowledge extraction of this invention, knowledge extraction is realized through acquiring an initial sentence group including one or more sentences, and then comparing the length of the initial sentence group with an expected length to determine the initial sentence group to be expanded according to the comparison result. Since the sentence groups are formed by consecutive sentences, it may be guaranteed that the sentence groups themselves have good coherence in logic, so that the final sentence groups obtained through expanding the initial sentence groups have good coherence in logic correspondingly. Thus, this invention may override the drawback of lacking logical coherence in extracted knowledge information in the prior art.

Abstract: The disclosed computer-implemented method for updating applications may include (1) identifying each version of an application, (2) determining possible upgrade paths to upgrade the application from an initial version of the application to a desired version of the application by, for each version of the application (a) creating a connection between the version and each subsequent version to which the version can be upgraded and (b) weighting each connection with a success rate that indicates the probability that the version will be successfully upgraded to the subsequent version, and (3) identifying, from among the possible upgrade paths, an optimal upgrade path for upgrading the application from the initial version to the desired version based on an analysis of both the combined weight and the combined length of the connections within each possible upgrade path. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A measurement initiation method for inter-frequency/inter-system cell reselection and UE thereof are described. A signal quality value of a current serving cell is obtained for many times, and a signal quality value smaller than or equal to a threshold of measurement initiation of a neighbouring inter-frequency/inter-system cell is stored storing until L signal quality values are obtained; a mean signal quality value is obtained by calculation according to the obtained L signal quality values, and when the mean signal quality value is greater than a signal quality reference threshold, UE initiates the measurement of the neighbouring inter-frequency/inter-system cell. By using the method and UE, the problem that UE frequently initiates measurement of a neighbouring inter-frequency/inter-system cell even when UE does not move or moves a little can be solved, the power of the UE can be saved, and the radiation produced by the UE on a mobile user can be reduced.

Abstract: A method for managing deduplication reference data may include (1) identifying multiple of data containers configured to store a plurality of deduplicated data segments that are referenced by multiple data objects within a deduplicated data system, (2) maintaining multiple reference databases including (i) a first reference database corresponding to a first subset of the data containers and (ii) a second reference database corresponding to a second subset of the data containers, the second subset differing from the first subset, (3) determining that a data object references at least one segment within a first data container within the first subset but does not reference any data segment within a second data container within the second subset and (4) updating the first reference database with information specifying that the data object references at least one data segment within at least one data container within the first subset of data containers.

Abstract: A method of authenticating an online read right of a digital content includes: receiving an online read first request from a terminal, the first request including first user information, obtaining first right information corresponding to the first user information, generating a first right model, obtaining first certificate information corresponding to the first right model, generating a second request including the first right model and the first certificate information, and authenticating the first certificate information and M function rights in the first right model.

Abstract: The present invention relates to the technical field of computer application, and more particularly to a method for allowing user access, a client, a server, and a system, for solving the problem that when a user accesses a server, it cannot be determined whether the user is allowed to continue accessing the server. The method comprises: a server receiving a type identifier and/or server identifier and user identity information sent from a client, for each application accessed by a login user, the client generating a type identifier and/or server identifier corresponding to the application; the server determining the number of type identifiers and/or server identifiers received for the user according to the user identity information, and determining whether to allow access of the user. The method can solve the problem that when a user accesses a server, it is determined whether the user is allowed to continue accessing the server.

Abstract: The present disclosure provides for implementing a two-level fingerprint caching scheme for a client cache and a server cache. The client cache hit ratio can be improved by pre-populating the client cache with fingerprints that are relevant to the client. Relevant fingerprints include fingerprints used during a recent time period (e.g., fingerprints of segments that are included in the last full backup image and any following incremental backup images created for the client after the last full backup image), and thus are referred to as fingerprints with good temporal locality. Relevant fingerprints also include fingerprints associated with a storage container that has good spatial locality, and thus are referred to as fingerprints with good spatial locality. A pre-set threshold established for the client cache (e.g., threshold Tc) is used to determine whether a storage container (and thus fingerprints associated with the storage container) has good spatial locality.
