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.

Abstract: Provided in the present disclosure are a method and apparatus for enhancing an RLC AM under exceeding maximum retransmissions and dual-no conditions. The method includes: when the number of retransmissions of the first message that has not been received by a receiving end reaches a preset threshold value, reconstructing the first message into a short message, and sending the short message to the receiving end; and when a polling timer expires and a dual-no condition is met, sending, to the receiving end, a second message having the minimum message SN in a set of messages for which positive acknowledgments of the receiving end have not been received. The dual-no condition is that no message in the sending buffer and the retransmission buffer can be sent at the current moment, and a new message cannot be sent due to no space in a sending window.

Abstract: A heel cup applied in a shoe is provided. The heel cup includes an inner surface and an outer surface. Each of the inner surface and the outer surface is a curved surface.
