Abstract: A method for judging aging degree of insulation of a cable T-connector based on a dynamic heat source is provided. Specifically, a temperature rise verification test platform of the cable T-connector is constructed, and heating of a cable core is simulated by using a controllable heat source. Influence of different thermal conductivity of an insulation layer on internal and external temperature responses of the cable T-connector is studied, and the temperature rise test platform is constructed to simulate the temperature response of the outer skin of the cable T-connector under the same temperature change of the internal heat source and compare the temperature response of the outer skin of the cable T-connector in different states through experiments, so as to obtain the corresponding relationship between aging degree and heat transfer capacity.

Abstract: An elastic terminal includes a cylindrical body with two ends having conductive contact portions abutted against a mated conductive terminal; and the cylindrical body is of a meshy cylinder structure enclosed by a braided layer braided regularly by conductive filaments, and has an elastic stretching deformation ability in an axial direction by means of a braided structure. The elastic terminal can elastically stretch and deform in the axial direction to achieve an elastic contact to another conductive terminal. A current transmission path is short, there is less surrounding air medium, and high-speed transmission can be achieved. During production of the cylindrical body, the conductive filaments can be braided regularly to form the braided layer by means of a braiding device, and the braided layer with a considerable length can be cut and welded to achieve batch and low-cost production of the terminals.

Abstract: Embodiments in accordance with this disclosure provide a system and method for predicting an attention level of a viewer corresponding to one or more portions of a media item. The method can include receiving a media item, segmenting the media item into one or more segments, each segment corresponding to a portion of the media item, identifying one or more characteristics associated with each segment of the one or more segments, providing the segmented media item and identified characteristics to a machine-learning model that has been trained using empirical data from identified user gaze locations on training media items, and generating a heat map that predicts the attention level of the viewer corresponding to the one or more segments of the digital media item based on the segmented media item, identified characteristics, and the empirical data.

Abstract: A microseismic interference positioning method and system based on a time-shift correlation coefficient, an electronic device and a storage medium are provided. The method includes: constructing a DTW time-shift correlation coefficient by using a DTW algorithm; multiplying the constructed time-shift correlation coefficient by an imaging operator; stacking all time-shift correlated gathers at a same grid point to obtain an imaging result for a single grid point; and stacking imaging results of all grid points to obtain a final imaging map characterizing a location of a microseismic source. A position with a maximum imaging value is the location of the microseismic source, thereby positioning the microseismic source. The method can solve a problem of reduced imaging resolution of cross-correlation imaging operators caused by wave propagation effects and noise, and improves the positioning performance under the influence of noise contamination.
