Abstract.Through the vacuum preloading test with three different arrangements and the in-situ curing treatment at different depths, the treatment effect reached the expectation, indicating that both the vacuum preloading method and the in-situ curing method can achieve good reinforcement effect. Among them, the local curing method has remarkable effect on treating waste engineering mud, and its bearing capacity is far beyond expectation, which can be used as the foundation of high-grade highway. After the test, it is found that the real air filtration test area can also improve the treatment effect by … Read more →

Abstract.Based on the lower accuracy of classic DV-Hop localization algorithm, this thesis puts forward an improved DV-Hop localization algorithm. In the second phase of the improved algorithm, through selectively modifying the shortest path table, the hop distance error of a hop anchor node is reduced by using the neighbour node overlapping estimation, and the average hop distance is calculated with the two poles of whole network and local network. Meanwhile, the hop count distribution from nodes to corresponding anchor nodes within the communication range of nodes is used to modify the hop distance … Read more →

Abstract.Based on the shortcomings of the current detection methods for wind power blades, an electromagnetic excitation biaxial fatigue loading system is designed. The loading method mainly adopts the principle of electromagnetic actuators. The loading part is mainly composed of electromagnet cores and coils. The blades exert electromagnetic force to achieve blade vibration. The dual-axis loading can be more in line with the actual working conditions of the blade. Electromagnetic loading mechanisms are installed in the two directions of the blade's waving and swaying respectively, and the … Read more →

Abstract.With the advancement of manufacturing processes, imaging sensors have become more and more sophisticated, the amount of image data generated is increasing, and application scenarios and functional algorithms have become more and more complex. The traditional serial processing method can no longer meet the real-time requirements of image processing. The use of hardware to accelerate image algorithms has become a basic trend in image acquisition and processing systems. Xilinx’s Zynq7000 series chip integrates a dual-core A9 series ARM processor (PS) and an A7 series FPGA (PL). The industry … Read more →

Abstract.Because stock prices are affected by a variety of factors, their market value may deviate from its intrinsic value in the short term. From a value investment perspective, stock value remains an important reference factor in long-term investment. This article takes the listed company Golden Seed Wine as an example, and takes the company's 2018-2020 annual report data to calculate the company's relative investment value through the price-to-earnings ratio, price-to-book ratio and dividend discount model, giving investors a certain investment reference.

Abstract.In order to strengthen the moral education work in colleges and universities, this paper takes the software testing course as an example to construct the ideological and political teaching mode of the first-class courses in ordinary colleges and universities. This paper organically combines teaching content with ideological and political elements, and proposes a student-centered teaching model and evaluation system reform. It has gradually formed a comprehensive training model of in-class and extra-curricular, pre-class and after-class, promoting learning through competition, and improving the … Read more →

Abstract.The stability of the river bank directly affects the integrity of the physical structure of the river, which in turn affects the ecological security of the river, and it also affects the safety of the people on both sides of the river. Construction near the banks of the Yangling section of the Weihe River Basin may cause disturbances to the stability near the riverbanks, and the stability of the riverbanks is also an important indicator of river water ecological security. Therefore, in view of the riverbank stability in the Yangling section of the Weihe River Basin, the bank stability of the … Read more →

Abstract.Today, when the new crown epidemic has become normal, college teaching must be ready for online teaching at any time, so how to ensure the quality of online teaching is a problem we must think about.In early 2020, in response to the COVID-19 outbreak, classes in the new semester were largely replaced by online teaching to ensure continued learning.Teachers are actively exploring effective online teaching methods to provide a good learning atmosphere for students at home to ensure that students have a good learning effect at home.This paper proposes an online teaching model based on active … Read more →

Abstract.With the increasing popularity of smart devices, the need for people to use mobile devices to surf the internet is growing. In order to meet the needs of users, major operators have launched 5G network, but only relying on mobile network can not meet the needs of users to surf the internet anytime and anywhere. In this case, the wireless router can provide users with a convenient and stable network environment. However, traditional home and private routers simply allow and provide wireless networking to certain groups of people. In order to break through the limitations of scope and usage … Read more →
