Bulk mineral ores are susceptible to liquefaction when being shipped in ocean bulk carriers. The liquefaction may occur suddenly and cause a dangerous list or even capsize of the vessel. In order to evaluate the liquefaction potential of the mineral ores during ocean shipping, this paper established a liquefaction risk assessment model for mineral ores through Analytical Hierarchy Process (AHP). An evaluation index system of liquefaction risk was constructed into an orderly hierarchical structure. Three crucial factors including vibration acceleration, moisture content and fine particles, were pairwise compared during the process. The order of the priority weight for the factors was moisture content (0.5834) > vibration acceleration (0.333) > fine particles content (0.0833). The risk value and value range of each factor were assigned on a five-point scale. Consequently, the overall value of the liquefaction risk was computed and the corresponding likelihood of liquefaction occurrence was assessed and validated. The liquefaction risk assessment model of bulk mineral ores was reasonable, which could provide useful information to avoid liquefaction of bulk mineral ores.

The hysteresis pendulum is that two or more pendulum balls are connected in series at the midpoint of the motor rotation axis, rotated under the action of the motor, and when they are stable, each pendulum ball moves in a uniform circumference in its own horizontal plane. The latter pendulum ball lags the former pendulum ball by π phases. The main factors that affect the stable motion of hysteretic pendulum are the mass of pendulum ball and cycloid length. Therefore, the study on the stability of hysteretic pendulum is a complex nonlinear problem. Firstly, mathematical modeling and analysis are carried out on the hysteretic pendulum, and then the control variable method is applied to study the influence of pendulum mass and cycloid length on the stability of the two pendulum balls. The experimental results are in good agreement with theoretical derivation, which provides a way of thinking for studying the motion law of multi-ball hysteretic pendulum.

Based on the new perspective of customer location and distribution demand of regional logistics distribution center, this paper integrates the similarity of customer attributes to optimize the matching of vehicle and customer information, and effectively avoids the unreasonable distribution of the number of vehicles and the frequency of delivery. At the same time, when the influence of vehicle speed, load weight and node distance on vehicle energy consumption are considered, a distribution time model with soft time window constraints is established, and the ant colony algorithm for node reversed processing is designed to solve the problem. The results show that the proposed method can reasonably plan the distribution of vehicles and achieve path optimization.

The rocket tank needs to be sprayed with adiabatic coating. However, due to the particularity of tank spraying conditions, robot path planning is difficult. To improve the above problem, this paper constructs the overall scheme of the spraying robot system by using an interactive motion sensor at the end of the robot. According to the characteristics of the motion control system guided by the sensor, the basic control model of the robot system is built based on admittance control, and the control performance of the parameters of the controller is analyzed. The parameters of admittance controller are selected. The spraying task segment of the robot is characterized by cosine similarity and the running speed of the robot. Based on the fuzzy control method, a modified admittance control model with variable admittance parameter configuration is constructed. The experimental results show that the modified control model can improve the response characteristics of the robot under variable working conditions.

Due to the effect of atmospheric light scattering, the quality of images taken under haze weather conditions will be seriously degraded. These characteristics affect the judgment and extraction of image features and reduce the application value of images. Image dehazing is therefore a necessary step in many computer vision tasks. In this paper, an end-to-end image dehazing algorithm Dehaze-GAN based on Cycle-GAN is proposed. In order to ensure that the structure of the images before and after dehazing is basically the same, the algorithm adds structure consistency loss on the basis of Cycle-GAN. The input of Dehaze-GAN is a hazy image and the output is a clean image. Dehaze-GAN is trained by a large number of hazy images and their corresponding clean images. The experimental results show that Dehaze-GAN is superior to other dehazing algorithms in both PSNR and SSIM dehazing performance indicators.

Micro-grid is one of the most effective ways to utilize renewable energy. It is of great significance to study how to realize the energy management of micro-grid and optimize the utilization of energy. Micro-grid is a system unit composed of distributed power generation, energy storage device, energy conversion device, load, control and protection device, etc. It is an autonomous system that can realize self-control, protection and management. Most of the power sources in the micro-grid are distributed power sources, such as wind turbine, photovoltaic power generation, micro gas turbine, fuel cell, super-capacitor, flywheel battery and other energy storage devices. Connecting them to the user end has the characteristics of low cost, low voltage and low pollution, and is the mainstream development direction of the current power system. This paper introduces the composition and control technology of micro-grid, as well as the energy management and simulation of optical storage micro-grid in island and grid-connected mode. In this paper, two modes of island and grid connection are simulated by Simulink. The results show that the optical storage micro-grid system with switching mechanism can effectively improve the utilization rate of photovoltaic power, realize the efficient integration and utilization of distributed power supply, and carry out load side operation management autonomously by switching switch.

As a basic identification technology, pedestrian detection provides technical support for many areas such as security monitoring and autonomous driving, and has a wide range of application scenarios. Based on the Single Shot MultiBox Detector (SSD) target detection algorithm, this paper trains a pedestrian detection system based on the SSD target detection framework with a self-built occlusion pedestrian dataset for the specific target of occlusion pedestrians. The test set and the re-annotated INRIA test set were used to compare the HOG+SVM based pedestrian detection system and the trained SSD model in OpenCV. The experimental results show that the detection effect of the SSD model is significantly better than the traditional pedestrian detection system based on HOG+SVM. The features learned by the deep convolutional neural network are more robust.

The nonlinear Lü-like system is reduced the uncertain conditions in the practical application process. In this paper, we take a new generalized Lü-like system, analyze the stability of the equilibrium point by the Routh-Hurwitz criterion, adopt Hopf bifurcation theory and combine with the time lag factors in the system to analyzes the time-delay Lü-like system. Through the judgment of the stability index, the time-delay parameters of the bifurcation are determined, and the type of Hopf bifurcation in the system is received. The feedback method controls the bifurcation parameters of the system. Combined with the linear state feedback method theory, the range of control coefficients in the system is proved when the bifurcation parameters of the system reach the control target. The results demonstrate that the overall stability of the generalized L ü-like system is improved when the time-delay parameters are introduced. The system has a relatively stable limit cycle, and the amplitude of the overall limit cycle is more stable.
