Auger drilling tool is widely used Chair in mining, exploration and security and other fields, is an important part of mine equipment, aiming at the best cutting speed and conveying speed of drill tool mismatch.In this paper, a new type of separated drill tool structure is proposed to realize the independent control of the bit cutting speed and the
To protect the information of video stream, many selective video encryption schemes have been proposed based on the H.265/HEVC video.However, most of the existing algorithms are not robust, thus failing to decrypt under packet loss.To further improve the robustness capability of video protection, a robust selective encryption scheme is proposed in
We propose that self-affirmation may endow people more psychological resources to buffer against the negative influence of rejecting unfair offers in the classic ultimatum game (UG) and further lead to a stronger tendency to reject those offers.We test this possibility by conducting an event-related potential (ERP) study about the UG, with the ERP
Abstract The petrol truck routing problem is an important part of the petrol supply chain.This study focuses on determining routes for distributing petrol products from a depot to petrol stations with the objective of Hand Print Kit minimizing the total travel cost and the fixed cost required to use the trucks.We propose a mathematical model that c
We proposed a novel framework of multiphase segmentation based on stochastic theory and phase transition theory.Our main contribution lies in the Pins introduction of a constructed function so that its composition with phase function forms membership functions.In this way, it saves memory space and also avoids the general simplex constraint problem
