Academic resource recommendation service system and method

The invention provides an academic resource recommendation service system and method. The method comprises the following steps: crawling academic resources on an internet by using an LDA (Latent Dirichlet Allocation)-based focused crawler, classifying the academic resources according to preset A types by using an LDA-based text classification model, and storing the academic resources in a local academic resource database, wherein the system further comprises an academic resource model, a resource quality value calculation module and a user interest module; implanting a tracking software module at a user terminal, combining interesting subjects and historical browsing behavior data of the user, respectively modeling the academic resource model and the user interest module by virtue of four dimensions such as the academic resource type, subject theme distribution, key word distribution and LDA latent theme distribution, calculating the similarity between the academic resource model and the user interest preference module, combining the resource quality value to calculate the recommendation degree, and finally perform academic resource Top-N recommendation for the user according to the recommendation degree. According to the method disclosed by the invention, personalized accurate recommendation of the academic resources is performed according to the identity, interest and browsing behaviors of users, and the working efficiency of scientific research personnel is improved.

Permeable in-situ leaching uranium mining leaching process for hydrochloric acid modified sand layer

ActiveCN106930738AStable controlImprove the ability of pumping and injecting fluidFluid removalPregnant leach solutionResource quality
The invention belongs to the technical field of in-situ leaching uranium mining and particularly relates to a permeable in-situ leaching uranium mining leaching process for a hydrochloric acid modified sand layer. The purpose is to solve the technical problem that traditional mining processes of sulfuric acid in-situ leaching and alkaline in-situ leaching cannot meet mining requirements under the condition of decreasing of the uranium resource quality. In practical use, the leaching process is stable in control and compact in joining, liquid extracting and injecting capacity is improved, oxidation of uranium minerals is accelerated and achieved, uranium-containing leachate is obtained, and the condition of production concentration treatment in later period can be met. In the leaching mining process at a Shihongtan 1# mining area, by adopting the leaching process, the liquid injecting capacity is increased from 108 m<3> / h to 132 m<3> / h; oxygen is dissolved effectively and injected into the ore-containing sand layer, the oxygen content in the leachate is 18 mg / l, the average peak value of the uranium concentration of the leachate is 27.8 mg / l, and the uranium concentration peak value of a single well is 64 mg / l; and accordingly the effects that the uranium resource of the mining area is exploited, and the recovery rate of the uranium resource of the mining area reaches 76.5% are achieved.

Cognitive system frequency spectrum sharing method on basis of space signal processing

InactiveCN102547741AImprove communication performanceMake up for the lack of resource selectionNetwork planningCognitive userSpatial correlation
The invention discloses a cognitive system frequency spectrum sharing method on the basis of space signal processing, which can be used for a cognitive radio system. The cognitive system frequency spectrum sharing method specifically comprises the following process that: firstly, transceiving ends of the cognitive system respectively acquire required channel information and construct different matrixes to carry out spacial related degree calculation of the transceiving ends after preprocessing the channel information; then according to the spacial related degrees calculated at the transceiving ends, a CBS (cognitive base station) combines the transmission gain to calculate an airspace resource quality factor; and finally, the CBS completes combined selection of an authorize channel and a characteristic mode according to an airspace resource quality factor calculating result, and after the result is notified to a cognitive user, the transceiving ends carry out combined signal processing, so that the simultaneous and same-frequency coexistence of the cognitive system and an authorization system is realized. The method disclosed by the invention has the advantages that all the transceiving ends participate in making a decision and the combined selection of the authorize channel and the characteristic mode is considered. The method has a more reasonable design. The cognitive communication performance is obviously improved.
