Abstract.Industrial Internet security incidents occur frequently, and the amount of industrial data is increasing exponentially. Efficient and correct detection of attacks is critical to industrial Internet security. The method is based on the concept of cloud-edge collaboration to detect malicious behaviors. Firstly, the data is normalized and preprocessed to reduce the differences caused by different feature scales, then the deep neural network(DNN) is used to extract the features of massive data, and finally the softmax function is used for classification. In order to verify the effectiveness of the … Read more →

Abstract.In order to study the influence of water content on the failure and deformation characteristics of sandstone, the indoor compression test and numerical simulation of sandstone under different conditions were carried out. The results show that with the increase of water content, the peak strain increases and the peak strength decreases. With the increase of water content, the transverse and longitudinal strains of rock samples gradually increase. This conclusion can provide reference for the safe construction of underground engineering in water-rich areas. Read more →

Abstract.Based on the viewpoint that the rock and soil are not homogeneous materials, the spatial variability of its mechanical parameters should be considered, and the influence of the spatial variability of the elastic modulus of the rock mass on the roadway deformation should be considered. Taking a coal mine roadway as the background, the spatial variability of elastic modulus of rock mass is characterized by means of random field theory. The random field data is simulated by Matlab software and the random field is discretized. The random field data is imported into each grid in the Abaqus model … Read more →

Abstract.With the development of global industry development, environmental pollution has become increasingly prominent, among which heavy metal ions are highly toxic, easily soluble in water and soil, and not easy to deal with. Long-term exposure to Cr (VI), Cu (II), Pb (II) and other heavy metal ions will cause a series of diseases. Therefore, how to remove heavy metal ions from soil has become one of the research hotspots in recent years. Read more →

Abstract.Soil salinization is one of the most important issues threatening agricultural production, food security and sustainability in arid and semi-arid regions worldwide. The improvement and comprehensive utilization of saline alkali soil is of great significance for cultivating healthy soil, ensuring global food security and mitigating climate change. This paper summarized the research progress of saline alkali soil improvement technology, and described briefly the causes of saline-alkali land. Moreover, the physical, chemical and biological methods of saline-alkali land improvement were analyzed. … Read more →

Abstract.Customized passenger transport has become one of the important travel tools in recent years because it can meet the diversified travel needs of passengers. Chongqing Pleasant Line company opened customized passenger transport as the research object. The relationship between latent variables and travel behavior intention was analyzed. The structural equation model was constructed based on the TPB and TAM models, and 402 valid data were collected. The empirical analysis was carried out using SPSS software, which provided an important basis for satisfying passengers' travel behavior intention. Read more →

Abstract.Based on the research theory and existing research methods of the horizontal bearing capacity of pile foundation in soft ground, this paper describes the current situation of the theory used to study the horizontal bearing capacity of pile foundation in soft ground at home and abroad, and then describes the current situation of the CPTU test method, DPP-BOTDA technology and numerical simulation methods applied to pile foundation monitoring, These research methods are proposed to provide some guidance for the follow-up research of similar projects.

Abstract.Evaluation is an important part in the process of English teaching. A scientific assessment method can improve teaching efficiency. The traditional test-oriented assessment tends to reduce students’ interest and motivation in English learning. As a form of formative assessment, portfolio assessment focuses on students’ learning process rather than learning results, which can play an unique role in students’ interest, attitude and ability in English writing. In order to promote a more scientific assessment system and know more about the current situation of the application in portfolio … Read more →

Abstract.The pier is the supporting structure of the bridge, and its role is pivotal, and we must pay attention to the related problems of the pier. Therefore, this paper discusses the local erosion mechanism of bridge piers, summarizes the influencing factors of erosion, and finally sorts out the ideal protection measures for bridge piers, which basically solves the problem of local erosion of bridge piers that bridges deal with at present.

Abstract.Myopia has become one of the important problems that affect the vision health of adolescents and children. In order to prevent myopia, various myopia prevention and monitoring systems have emerged in recent years. This paper aims to research and design a sensor-based monitoring system for myopia prevention. The system includes multiple functional modules such as vision detection, eye monitoring, visual training and data management, which can monitor and analyze the user's vision status in real time, and provide personalized myopia prevention programs and visual training plans. In the process … Read more →

Abstract.In the new era of socialism with Chinese characteristics, professional courses and ideological and political courses should develop in the same direction and synergy.How to effectively integrate ideological and political elements into professional courses and build a large pattern of all-round education is a new topic for professional teachers to cultivate people by virtue. In teaching design of "fluid transmission and distribution network" course, based on the Guiding Outline of Ideological and Political Construction of Higher Education Courses issued by the Ministry of Education, the … Read more →

Abstract.In the field of second language acquisition, Hulstijin (2001) believes that vocabulary incidental acquisition usually refers to the fact that when learners perform meaningful second-language language use or learning activities, such as reading articles, watching movies, or listening to music, their attention is not focused on vocabulary learning, but inadvertently acquires part of the knowledge about vocabulary, which is a kind of vocabulary cognitive activity that occurs incidentally when attention is focused on other activities. This vocabulary learning is a byproduct of second language … Read more →

Abstract.Old buildings because of long service life or natural damage, easy to appear durability, bearing capacity, stability decline, in order to ensure the safe use of building structure must take reinforcement measures. Increasing section method, carbon fiber cloth outsourcing, pasting steel plate method, planting reinforcement method and so on are commonly used reinforced concrete building structure reinforcement technology, but each technology is not the same application conditions and application effect. In this paper, the reinforcement and renovation project of a frame structure industrial plant … Read more →
