    Abstract: The present invention discloses an embedded urban design scene emulation method and system. The method includes the following steps: constructing a status quo urban three-dimensional model scene according to collected oblique photography data; loading a three-dimensional model of urban design to a scene, and extracting geometric attributes for generation of buildings; unifying a space coordinate system of models and scenes, and automatically determining a space matching degree by taking buildings as a basic unit, and marking matched buildings with Y and mismatched buildings with N for distinction; for a region with the buildings marked with N, performing a local flattening operation in a three-dimensional model scene of oblique photography to flatten stereo data; for a region with the buildings marked with Y, performing real-time space editing in the three-dimensional model of urban design to hide the marked buildings; and opening two sets of processed space data to implement mosaic display. The present invention can conveniently embed a three-dimensional model of urban design into a status quo three-dimensional model of oblique photography for scene emulation, and provides technical and method supports for digital presentation and management of urban design achievements.

    Abstract: The present invention discloses an automatic urban land identification system integrating business big data with building forms, including a data acquiring and inputting module, a database construction module, a machine learning training module, an automatic identification module, and a data outputting module. The system automatically identifies an urban land by extracting a data distribution feature of an urban business site and a multi-dimensional form feature of an urban spatial three-dimensional entity. The present invention can be used for the determining of land usage of an urban plot in the field of urban planning and design, to achieve efficient and automatic refined identification of land usages of cities of different scales based on an artificial intelligence system, providing an efficient and convenient surveying and mapping approach and reference for surveying and mapping of the current urban construction land, and effectively saving time costs of manual surveying and mapping.

    Abstract: The present invention discloses an identification method of content metadata for cyber content sharing and governance (an MDCCSG identification method for short) and an application method of MDCCSG identifiers. The identification method is proposed to meet the requirements of big content data sharing and governance in a big data and pan-media environment, and is suitable for generating uniform identifiers for various types of content resources. The corresponding application method of MDCCSG identifiers can effectively support high-efficiency sharing and governance of big content data. The MDCCSG identification method includes three parts: a uniform description framework of content metadata, a uniform specification method for content metadata, and definition of core MDCCSG identifier elements. The identification method not only can describe rich semantic information of contents in details, but also has built-in capabilities of content trust authentication and security guarantee. Various content sharing and governance applications can be developed based on the MDCCSG identifiers, and many important functions for big content data can be effectively supported, including efficient aggregation and distribution, personalized active service, semantics-based deep analysis, authentication and registration, source tracing and responsibility investigation according to laws and the like.

    Abstract: The present invention provides a method and apparatus for dewatering a biological solid material employing both microwave irradiation and solvent extraction. The method comprises microwave irradiation pretreatment, solvent extraction dewatering, solid-liquid separation, and solvent recovery. Through microwave irradiation of an aqueous biological solid material, gaps in the solid material are increased, and the biological material is fractured, thus releasing more bound water in the solid material. Subsequently, the microwave-irradiated biological solid material is brought into full contact with an organic solvent, allowing the solvent to absorb and extract moisture from the solid, thus removing moisture from the solid. The aqueous solvent is then subjected to evaporation under reduced pressure or gasification under reduced pressure in a separation apparatus so as to separate the moisture and the solvent. The solvent is then compressed, condensed and recovered for recycling. Also provided is a device for implementing the dewatering method.
