  • Publication number: 20230058520
    Abstract: A traffic flow forecasting method based on Deep graph Gaussian processes includes: S1, with respect to the dynamics existing in a spatial dependency, using an attention kernel function to describe a dynamic dependency among vertices on a topological graph, and using the attention kernel function as a covariance function in an Aggregation Gaussian process to extract dynamic spatial features; S2, obtaining a Temporal convolutional Gaussian process from weights at different times and a convolution function that obeys the Gaussian processes, and obtaining temporal features in traffic data by combining the Aggregation Gaussian process; S3, constructing a Deep graph Gaussian process method integrating a Gaussian process and a depth structure from the Aggregation Gaussian process, the Temporal convolutional Gaussian process and a Gaussian process with a linear kernel function, inputting a data sample to be forecasted into the Deep graph Gaussian process method to obtain a forecasted result.

  • Publication number: 20080258858
    Abstract: A non-burnable varistor, comprises a base slice having two opposite surfaces, a first elicit pole electrically connected to one surface of the said base slice, a second elicit pole electrically connected to the other surface of the said base slice. Outside each of the said two opposite surfaces of the base slice a low-melting-point metal conductor layer is respectively situated, which is melted at the temperature of 155˜450° C., and the two layers are not electrically connected by any good conductor. When the non-burnable varistor base is struck and burned through to form an arc, the low-melting-point metal are melted and go into the arc in the form of gas or liquid, to depress the resistance of the arc nearly to a short estate. So the arc current can be cut off by the over-loading security mechanism as over-current protective fuses or breakers, before the coat of the non-burnable varistor caught on fire, to prevent the occurrence of fire accident.
