    Abstract: Provided is a sensory quality evaluation method for tobacco and tobacco products using an electronic nose instrument. The electronic nose instrument includes a gas sensor array module, an automatic smoke sampling system, a computer control and data analysis system, and an automatic ignition device. These components are integrated in a test box to make the instrument be structure miniaturization and work automation. The large tobacco data is established, in which the relationship between the responses of gas sensor array and the brand labels and sensory quality index scores by testing a large number of standard cigarette samples. A cascade type of modular neural networks is proposed with revised activation function and new decision-making and quantification rules to simulate the smoking and evaluating process of the professional panel.

  • Patent number: 10736943
    Abstract: A method was developed to prepare silk fibroin microspheres using lipid vesicles as templates to efficiently load therapeutic agents in active form for controlled release. The lipids are subsequently removed through the use of a dehydration agent, such as methanol or sodium chloride, resulting in ?-sheet structure dominant silk microsphere structures having about 2 ?m in diameter. The therapeutic agent can be entrapped in the silk microspheres and used in pharmaceutical formulations for controlled-release treatments.

  • Publication number: 20200234170
    Abstract: A method for classifying eco-geological environment types based on coal resource exploitation solves the problem in the prior art of a lack of combined consideration of different geological and ecological environments on the surface in a to-be-mined area before coal mining. Based on surveys of ecological, hydrological, and geological information of the area, and by means of a Fuzzy Delphi Analytic Hierarchy Process (FDAHP) and weighted fuzzy C-means clustering, the present invention determines different eco-geological environment types. According to the existing ecological, hydrological, and geological information, the present invention can rapidly and effectively classify the different eco-geological environment types, and further determine eco-geological features and their sensitivity to coal resource exploitation.

  • Patent number: 10527542
    Abstract: The present invention relates to a method of calculating a Topography Adjusted Vegetation Index (TAVI) based on a band ratio model and a solar altitude angle. The method includes the following steps: obtaining the apparent reflectance data of a remote sensing image through image preprocessing, analyzing the quality of the image and numerical distribution, calculating a Shadow Vegetation Index (SVI), and constructing a TAVI combinational algorithm: TAVI = B ir B r + f ?
