  • Patent number: 12270791
    Abstract: A method, a system and a device for determining interlaminar shear strength of a composite laminated plate are provided. The method includes following steps: constructing a force-displacement curve of a composite laminated plate specimen based on strain data, corresponding to different displacements of the indenter, of the composite laminated plate specimen; determining a dominant strain based on plane strain nephograms; reading any defect in the plane strain nephogram corresponding to one displacement as a current defect, and determining a test force acting on the whole composite laminated plate specimen corresponding to the reference displacement of the indenter as a critical strain value; determining a product of the critical strain value and shear modulus under the dominant strain as the shear strength between adjacent single layers to be tested.

  • Publication number: 20250110255
    Abstract: A method of determining meteorological information, an electronic device and a storage medium are provided, which relate to a field of artificial intelligence technology, and in particular to fields of deep learning and large models. The method includes performing a feature extraction on meteorological raster data of a target region within a target time period to obtain a meteorological feature vector; inputting to-be-processed meteorological data of the target region within the target time period into a large language model to obtain a text summary including a meteorological information determination manner; performing an information enhancement processing on the meteorological feature vector by using the text summary to obtain an information enhancement result; and performing a self-attention processing on the information enhancement result to obtain a meteorological information determination result output for the to-be-processed meteorological data.

  • Patent number: 10962371
    Abstract: A method for vehicle tracking and localization includes receiving, by a controller, odometry data from a sensor of the first vehicle; geospatial data from a Global Positioning System (GPS) device of the first vehicle; inertial data from an inertial measurement unit (IMU) of the first vehicle; estimating an estimated-current location of the first vehicle and an estimated-current trajectory of the first vehicle using the odometry data from the sensor, the geospatial data from the GPS device, and the inertial data from the IMU of the first vehicle; inputting the inertial data into a Bayesian Network to determine a predicted location of the first vehicle and a predicted trajectory of the first vehicle, and updating the Bayesian Network using the estimated-current location and the estimated-current trajectory of the first vehicle using the odometry data and the geospatial data.

  • Patent number: 9284535
    Abstract: A method for producing laccase by liquid fermentation of Lentinus edodes comprises the following steps of: (1) inoculating strains of Lentinus edodes into the PD liquid fermentation medium to perform activation culture and obtain a seed liquid; (2) inoculating the seed solution into a liquid fermentation medium to perform liquid fermentation culture, then adding an expansin solution to perform further culture, separating the supernatant to obtain a ferment solution; (3) extracting laccase from the ferment solution. A plant expansin and an optimized fermentation method are applied for producing laccase by liquid fermentation of Lentinus edodes, which increases the liquid fermentation output of laccase of Lentinus edodes remarkably, by more than 3 times in comparing with traditional fermentation production methods.
