  • Publication number: 20210150103
    Abstract: The disclosure discloses a system and method for predicting a vibration of a bicycle when being rode on a road. The method first uses a pressure film to obtain a contact interface between a road and a bicycle tire, and then, based on the contact interface, a unit bearing area (Bu) and an average stress peak distance (Spa) are calculated. Next, taking the above parameters as variables, a predicted vibration value (Pv) is calculated based on calculation formulas provided by the present disclosure. Finally, the predicted vibration value Pv is compared with a comfort-level threshold perceived by a cyclist of the present disclosure, which can quickly and effectively grade and predict a comfort level when riding a bicycle on a section of an asphalt road.

  • Publication number: 20210144418
    Abstract: The present disclosure provides method and apparatus for providing video recommendation. At least one reference factor for the video recommendation may be determined, wherein the at least one reference factor indicates preferred importance of visual information and/or audio information in at least one video to be recommended. A ranking score of each candidate video in a candidate video set may be determined based at least on the at least one reference factor. At least one recommended video may be selected from the candidate video set based at least on ranking scores of candidate videos in the candidate video set. The at least one recommended video may be provided to a user through a terminal device.

  • Patent number: 10988561
    Abstract: A method for industrial production of a butadiene-isoprene copolymer rubber having a trans-1,4-structure (TBIR) and an apparatus for implementing the method. The production method includes: pumping a predetermined amount of a butadiene and an isoprene into a polymerization reactor, and performing bulk polymerization in the presence of a catalyst to obtain TBIR; performing extrusion, devolatilization, granulation and drying on the produced TBIR, and then packaging the produced TBIR; and separating unreacted monomers by a recovery and separation device followed by separately refining the unreacted monomers, and then returning the unreacted monomers to a batching device or a storage tank. The production apparatus has a recovery and refining unit, a polymerization unit, a post-treatment unit and a utility unit. By the production apparatus and the production method industrial production of TBIR by bulk polymerization is realized.

  • Publication number: 20210010904
    Abstract: The present disclosure provides a method and an apparatus for evaluating a degree of injury of a rider's head colliding with a pavement and a test method for testing the apparatus. An impact acceleration of a head model falling from a certain height and hitting the pavement is obtained through a self-made test apparatus, a TBS value is calculated after processing the obtained impact acceleration, and a possibility of the degree of the injury to the rider's head colliding on a test pavement after falling is obtained by inquiring a look-up table of possibility of injury degree of the head of the rider corresponding to the TBS provided by the present disclosure, for evaluating safety hazard when falling on the pavement.

  • Patent number: 10793779
    Abstract: The present disclosure provides a method for separating soluble organic matter in petroleum coke, including: drying the petroleum coke to obtain pretreated petroleum coke; extracting the pretreated petroleum coke sequentially with petroleum ether, carbon disulfide, ethanol, acetone-carbon disulfide mixture and tetrahydrofuran to obtain an extract and the treated petroleum coke, wherein the extract includes soluble organic matter. The method provided by the present disclosure employs extractants with different polarities, i.e., petroleum ether, carbon disulfide, ethanol, acetone-carbon disulfide mixture and tetrahydrofuran, to extract petroleum coke sequentially, so as to detect the composition of the soluble organic matter in petroleum coke at the molecular level, realizing the separation of soluble organic matter in petroleum coke at the macro molecular level, as well as the determination of molecular structure of soluble organic matter in petroleum coke by modern detection processes.

  • Patent number: 10710906
    Abstract: The present disclosure relates to wastewater treatment, and more particularly to a method for treatment of petrochemical spent caustic wastewater. The method includes the following steps: a) adjusting the pH of petrochemical spent caustic wastewater to 7 to 12, standing, removing the organic layer, and obtaining the pretreated wastewater; b) activating a plasma reactor loaded with resin photocatalyst, passing the pretreated wastewater into the plasma reactor for treatment in the presence of oxygen, and obtaining the treated wastewater. The method provided by the present disclosure can effectively improve the COD removal rate of petrochemical spent wastewater, and the whole treatment process is carried out under normal temperature and normal pressure, with a simple process and the ability to realize continuous operation. The experimental results show that the COD removal rate of petrochemical spent caustic wastewater using the method provided by the present disclosure is above 98%.

  • Patent number: 10674930
    Abstract: Single-unit EEG sensors contain multiple closely spaced dry electrodes that can hook onto skin and associated electronic circuitry such as amplifiers, A/D convertors, wireless transmitters, and a power source such as a battery. The electrodes can be separated by about 20 mm or less, and the associated circuitry can be situated within a volume defined by the multiple electrodes. The single-unit sensors hook onto the skin using a tooth surface so that a rotation of the sensor secures and electrically connects the sensor to the skin.
