Abstract: The disclosure relates to method and apparatus for operating image data. The method includes: reading matrix data from the image data based on a matrix size, M rows and N columns, of an image operator (220); calculating column data in the matrix data with a single calculation instruction corresponding to the image operator, to obtain an intermediate calculation result (240); multiplexing and rearranging the intermediate calculation result into N rows of cached data (260); calculating matrix elements of a target column in the N rows of cached data with the single calculation instruction, to obtain a calculation result of the matrix data under the single calculation instruction (280); and outputting the calculation result as an image processing result of the matrix data by the image operator (300).

Abstract: A method for assessing sliding electrical contact performance of an electric locomotive pantograph-catenary system includes determining a current manifestation of a catenary-following ability of a pantograph to a catenary of the pantograph-catenary system, wherein the current manifestation is one or more of a pressure difference, a time delay, and a curve difference; and performing comparison between a fluctuating pressure curve related to a fluctuating pressure of the catenary and a catenary-following pressure curve related to a catenary-following pressure of the pantograph over time under the current manifestation, and rating the catenary-following ability of the pantograph under the current manifestation according to a result of the comparison. By implementing the method, precise assessment of the sliding electrical contact performance can be achieved.

Abstract: Electronic device includes: first interface configured to connect to first device; second interface configured to connect to second device; processing module, which is connected to the stated first interface and second interface and is capable of determining the data transmission mode of the first interface based on the connection status of the first interface and the first device. If the first interface is in a first data transmission mode, the stated processing module is also configured to adjust the second interface to be in a second data transmission mode. The difference between the stated first date transmission mode and the stated second data transmission mode is that the data transmission direction is different.

Abstract: The present disclosure relates to a yield prediction method for a fractured horizontal well based on simulated special mechanisms of shale gas.
