The electromagnetic gas volume control actuator of reciprocating compressor is a device that using electromagnetic driving force to control the opening and closing of the inlet valve. In order to solve the problems of ordinary pulse voltage control method, such as the contradiction between high frequency fast response and low seating speed, poor anti-disturbance performance and so on, an adaptive integral sliding mode control based on backstepping method was proposed. Firstly, a nonlinear model that considering disturbance was established for the electromagnetic gas volume control actuator. Secondly, the high-order system of electromagnetic gas volume control actuator was decomposed into two serial low-order subsystems by using the backstepping design idea. On this basis, a composite control method was designed, which combined the characteristics of sliding mode control, adaptive control and integral control. Finally, through the AMESim-Simulink joint simulation platform, the control method was analyzed and compared from different aspects with the traditional PID control method and the sliding mode control method. The experimental results show that the average tracking errors of the electromagnetic gas volume control actuator in the ejection and withdrawal processes are respectively 9. 6% and 10. 8%, the average seating speeds are respectively 0. 32 mm/s and 0. 98 mm/s. The maximum displacement offset caused by the external disturbance is 1. 3%. It shows that the adaptive integral backstepping sliding mode control method can ensure the fast convergence of the tracking error, improve the displacement tracking accuracy, effectively reduce the seating impact of the electromagnetic gas volume control actuator, and have strong robustness to external disturbances.

Icing has posed the significant impact on the aerodynamic performance and power output in wind turbines, particularly on the airfoil at the blade tip position. Therefore, it is particularly important to evaluate the performance of wind turbines before and after icing for real operating. According to the conditions of GW87/1500 wind turbine, this study aims to analyze the icing behavior of the blade tip airfoils and the aerodynamic performance using computational fluid dynamics. The objects were also adopted as the commonly-used DU-96W-180, DU-95W-180, and S810 airfoils at the blade tips of the wind turbine. Three kinds of operating conditions were set as the light, medium and heavy icing. The results show that there were the similar icing mass, thickness and limit of DU95-W-180 and DU96-W-180 airfoils. The smaller icing mass and thickness were found on the S810 airfoils, which was concentrated mainly on the lower surface of the airfoils; Under the light icing conditions, the angles of attack corresponding to the maximum lift-to-drag ratios of the three airfoils were the same as those under the uniced condition, which were about 7°. The angles of attack were advanced from 13° to about 11°, corresponding to the peak lift coefficients of the DU96-W-180 and DU95-W-180 airfoils. While the aerodynamic performance of the S810 airfoil was deteriorated more significantly, where the angle of attack was advanced from 13° to about 9° corresponding to the peak lift coefficient; Under the moderate icing conditions, the angles of attack were still about 7° corresponding to the maximum lift-todrag ratios of DU95-W-180 and DU96-W-180 airfoils, while those of S810 airfoils were advanced to around 5°. The peak lift coefficients were advanced from 13° to 9° corresponding to the peak lift coefficients of the DU96-W-180 and DU95-W-180 airfoils, while those of the S810 airfoils were advanced from 13° to 5°. Moreover, the lift and drag coefficients varied even more drastically. The aerodynamic performance of the three airfoils decreased more significantly under heavy icing conditions. The pressure distribution and surface flow pattern of the blade tip airfoils were measured under different icing conditions. There was the destroyed distribution of surface pressure on the three icing airfoils. The pressure coefficient at the leading edge of the airfoils was oscillated to reduce the lift, indicating the decreasing difference of pressure. There was the great variation in the flow distribution on the airfoil surface before and after icing of the three blade tip airfoils at 5° angle of attack. There was the increase in the separation vortices between the leading and trailing edge position of the DU95-W-180, DU96-W-180, and S810, when the icing condition was ranged from the light to the heavy. The flow separation was aggravated at the boundary layer of the airfoil surface. The better aerodynamic performance of DU96-W-180 airfoil was achieved before and after icing. The finding can be applied to optimize the airfoils of wind turbine blades in cold regions, in order to improve the energy utilization efficiency of wind turbines. [ABSTRACT FROM AUTHOR]

The Tang Dynasty, as one of the most prosperous eras in ancient China in terms of economy and culture, had distinctive and vibrant clothing patterns and color designs. These designs encapsulate the essence and cultural representation of Tang Dynasty attire, providing valuable creative inspiration and reference for contemporary fashion design. Currently, research on the color of clothing patterns of the Tang Dynasty mainly involves traditional subjective qualitative analysis and a small amount of quantitative color analysis. Quantitative analysis is primarily focused on analyzing and applying color samples of clothing patterns that have faded, been damaged, or polluted, which can lead to inaccuracies and biases in color analysis due to the deteriorated samples. Therefore, there is a need for image restoration and color restoration of the existing Tang Dynasty clothing patterns. At present, image restoration algorithms are mainly divided into traditional image restoration algorithms and deep learning image restoration algorithms. Among them, deep learning image restoration algorithms rely on the processing of a large amount of data and resources. Considering the scarcity of preserved images of Tang Dynasty clothing patterns, deep learning algorithms are not suitable. Therefore, the traditional image restoration algorithm FMM (fast marching method), which is technologically mature, is chosen. This algorithm does not depend on large-scale data computation and can quickly and accurately restore damaged areas. At the same time, due to its characteristic of repairing from the boundary inward, it can better cope with the main narrow and long damaged areas in the disease of Tang Dynasty clothing patterns while maintaining structural integrity and high clarity. Therefore, this algorithm is selected for the restoration of preserved images of Tang Dynasty clothing patterns. To more accurately clarify the color preferences and matching rules of Tang Dynasty clothing patterns, this study takes the preserved images of Tang Dynasty clothing cultural relics as the research object and proposes a method for the color restoration and reuse of Tang Dynasty clothing patterns based on the FMM image restoration algorithm and network analysis. This method first uses a color segmentation algorithm to classify and segment the image in the Lab space, and then repairs and restores the damaged and faded areas based on the FMM algorithm. Secondly, the K-means clustering algorithm is used to perform color clustering calculations on the restored image to obtain the secondary node degree and adjacency relationships of the image colors, thereby clarifying the explicit color and matching knowledge of Tang Dynasty clothing patterns. Then, the efficiency matrix algorithm is introduced to weight the implicit color matching logic in Tang Dynasty clothing patterns, and the influence matrix between color nodes is established by using expert evaluation and the Likert scale. Finally, the efficiency matrix algorithm is used to construct a color model of Tang Dynasty clothing patterns. Ultimately, scarves are used as a creative carrier for design to explore the feasibility of expanding the color matching of Tang Dynasty clothing patterns to contemporary fashion design. Through comparative experiments between traditional image restoration methods and deep learning restoration methods, as well as comparative analysis of objective evaluation indicators such as PSNR and SSIM, this method shows superiority in color restoration accuracy and image quality. This method can not only effectively analyze the color information of Tang Dynasty clothing patterns, but also assist designers in accurately using its color matching for design, providing a new solution for the protection, inheritance, and innovative development of the color of Tang Dynasty clothing patterns. Although this study has proposed a method for the color restoration and reuse of Tang Dynasty clothing patterns, there are several issues that require ongoing refinement and exploration. First, it is necessary to further optimize the image restoration algorithm to improve the restoration capability for images with few samples but more severe and complex instances of damage. Secondly, it is necessary to combine artificial intelligence technology to achieve automation and intelligence of color restoration and reuse. Finally, it is necessary to strengthen interdisciplinary cooperation, integrate knowledge from various fields such as design, digital protection of cultural heritage, and computer graphics to form a more comprehensive research system. This will further promote the deep integration of traditional culture with modern design and provide more accurate references for the study of the color of Tang Dynasty clothing patterns.

Liquefaction of coral soil sites is one of the typical earthquake disaster phenomena in port projects, coastal facilities, and islands. Coral soil has the characteristics of wide gradation, high fine particle content, and easy breakage. The sand pluviation method is an important modeling method for studying saturated site models and unit test liquefaction. In view of the delamination problem that occurs when the sand pluviation method is used to prepare coral soil foundation models, the independently developed large-scale sand pluviation device, high-speed camera and PFC3D discrete element numerical simulation are used. By simulation, the effects of fine particle content, flow rate, drop distance and moving speed of sand outlet on layered phenomena were analyzed. The generation mechanism of the layered phenomena was revealed, and corresponding control methods were established. The test results show that compared to the drop distance and the moving speed of the sand outlet, the fine particle content and flow rate are the main factors affecting layered phenomena. As the fine particle content increases, the layered phenomena gradually weakens. As the flow rate increases, the layered phenomena gradually becomes obvious. When the drop distance and the moving speed of the sand outlet reach a certain range, the layered phenomena will no longer increase, and the changes were not obvious. High-speed camera analysis shows that the separation of coarse and fine particles occurs when the coarse and fine particles move at the sand outlet, and there is an obvious separation boundary. The results show that the layered phenomena is caused by gravity, air drag force, and the lateral movement of the sand outlet. The PFC3D discrete element was used to simulate the process of sand pluviation molding. The simulation results were highly consistent with the results of photos taken by high-speed cameras, which proved the feasibility of the PFC3D numerical simulation method. Finally, combined with influencing factors such as flow rate, falling distance, and sand outlet moving speed, a method that can effectively control the layered phenomena of sand pluviation is proposed to provide guidance for the preparation of large-scale wide-gradation coral soil models.

The experiment aimed to optimize the fermentation conditions for the high-yielding surfactin-producing strain Bacillus subtilis BYA-KC-4 and to screen for the best conditions for surfactin production. The experiment determined the levels of factors affecting surfactin production through single-factor tests. The Box-Behnken central composite design was used to further optimize the fermentation condition parameters. The results showed that under the optimal fermentation conditions, namely a temperature of 33 ℃, an initial pH value of 6.8, an inoculum volume of 4.8%, and a rotation speed of 201 r/min, the yield of surfactin reached 560.25 mg/L. Compared with the 425.36 mg/L before optimization, it increased by 1.32 times. The study indicates that the experiment can provide a reference for surfactin production by Bacillus subtilis BYA-KC-4 and for industrial production. [ABSTRACT FROM AUTHOR]

Non-contact voltage measurement is of great significance for intelligent and digital transmission lines of new power systems and real-time characterization of line health. At present, there are problems in non-contact voltage measurement, such as poor determination of measurement point position, low calculation accuracy and great influence by environmental noise, which seriously restricts the engineering application of non-contact voltage measurement methods. A measurement point optimization and voltage inversion calculation method for transmission line sensors combining genetic algorithm and particle swarm algorithm was proposed. Firstly, in order to reduce the influence of electromagnetic interference on non-contact measurement, according to the principle of electric field coupling measurement, the number of observation matrix conditions was taken as the fitness function, and the observation point of the electric field sensor was optimized. Secondly, taking the difference between the offline electric field strength theory and the measured value as the objective function, the genetic particle swarm algorithm was used to calculate the inversion voltage. Finally, the test was carried out under the three-phase test platform built. The results show that under the application of 10% electromagnetic noise, the voltage measurement error is less than 5%, and the environmental noise interference of the voltage inverse calculation result is reduced by 12. 9% .
