“…In the process of the rise, slow progress, and explosive development of intelligent manufacturing, different scholars have made different definitions of intelligent manufacturing based on the background at that time. One of the main reasons for the development of manufacturing informatization is that informatization can improve the competitiveness of the manufacturing industry [23].…”

Smart city construction is the inevitable product of scientific development and transformation of life by building digital cities, building the Internet of Things, and making city management systems simple and intelligent through cloud computing. Smart city is a new generation information technology. Make full use of the advanced form of urban informatization based on the next generation innovation of knowledge society in all walks of life in the city. Cloud computing is a new network application concept. The core concept of cloud computing is to take the Internet as the center, and provide fast and secure cloud computing services and data storage on the website, so that everyone who uses the Internet can use the huge computing resources and data center on the network. The role of smart city engineering infrastructure is to build the infrastructure of this platform, so that smart cities can operate effectively, such as deformation test of ferroelectric materials, particle suitability analysis of ferroelectric materials, etc., This research is oriented to the intelligent manufacturing of new infrastructures in smart cities and analyzes the performance of ferroelectric materials in construction, aiming to better grasp the performance of ferroelectric materials and provide constructive suggestions for smart manufacturing in smart cities. The article first understands and states the related concepts, related construction requirements, development status and problems that need to be solved for smart city smart manufacturing by consulting relevant materials; then, it discusses the ferroelectric materials involved in the construction, analyzes the data of piezoelectric properties, etc., which will help to give more clear guidance on the process of tooling design; finally, the application link of ferroelectric materials is tested, and the deformation of ferroelectric materials and this premise are discussed on the problem of intelligent manufacturing efficiency and intelligent manufacturing efficiency. The experimental results show that the maximum value in the group of smart manufacturing benefits is 559.37; the maximum value between groups is 172.35. For efficiency of smart manufacturing, the maximum value between groups reaches 187.07; the maximum value in groups is 286.35. Whether it is a significant analysis of smart manufacturing benefits or smart manufacturing efficiency, the experimental results are quite impressive.

In order to further solve the problems existing in the process of land resource management of relevant departments of land and resource management, realize the information management of land resources, and promote the efficient utilization of land resources and scientific information management, this paper proposes a land resource management system based on Internet of things technology. With the help of resource allocation and management algorithm based on the needs of Internet of things users and land resource management requirements, this paper constructs a land resource management system based on Web and mobile network platform. The system development takes Java as the background programming language, constructs the database based on Oracle 9i, and uses GIS/GPS and other electronic map functions to realize the accurate display and resource sharing of land resource information. In the system test, 60, 120, 240, and 360 concurrent users are simulated to access the system at the same time. The connection success rates of the corresponding system are 97.2%, 97.5%, 98.3%, and 96.6%, respectively, which fully verifies the good performance of the system; it can be widely used in land resource information management.

“…However, many cities in high-income countries stimulate dispersion of households away from the city centres, emphasize more environmentally friendly and efficient modes of transportation, and restrict the access to city centres creating low and ultralow emission zones [ 43 ]. These aspects make the association between air pollutants and mobility vary among cities in low- and middle- compared to high income countries [ 44 ]. We used HDI adj to group cities and compensate for such variables, allowing for a better analysis of associations between mobility and air pollution.…”

Changes in air pollution due to COVID-19 lockdowns in 2020: Limited effect on NO₂, PM_2.5, and PM₁₀annual means compared to the new WHO Air Quality Guidelines

et al. 2022

Background Lockdowns have been fundamental to decreasing disease transmission during the COVID-19 pandemic even after vaccines were available. We aimed to evaluate and compare changes in air quality during the first year of the pandemic in different cities around the world, investigate how these changes correlate with changes in mobility, and analyse how lockdowns affected air pollutants’ annual means. Methods We compared the concentrations of NO 2 , PM 2.5 , and PM 10 in 42 cities around the world in the first months of the pandemic in 2020 to data from 2016-2019 and correlated them with changes in mobility using Human Development Indexes (HDIs). Cities with the highest decreases in air pollutants during this period were evaluated for the whole year 2020. We calculated the annual means for these cities and compared them to the new World Health Organization (WHO) Air Quality Guidelines. A Student’s t - test (95% confidence interval) was used to evaluate significant changes. Results Highest decreases in NO 2 , PM 2.5 , and PM 10 were between -50 and -70%. Cities evaluated for the whole year 2020 generally showed a recovery in air pollution levels after the initial months of the pandemic, except for London. These changes positively correlated with year-long mobility indexes for NO 2 and PM 2.5 for some cities. The highest reductions in air pollutants’ annual means were from -20 to -35%. In general, decreases were higher for NO 2 , compared to PM 2.5 and PM 10 . All analysed cities showed annual means incompliant with the new WHO Air Quality Guidelines for NO 2 of 10 μg/m 3 , with values 1.7 and 4.3 times higher. For PM 2.5 , all cities showed values 1.3 to 7.6 times higher than the WHO Guidelines of 5 μg/m 3 , except for New Delhi, with a value 18 times higher. For PM 10 , only New York complied with the new guidelines of 15 μg/m 3 and all the other cities were 1.1 to 4.2 times higher, except for New Delhi, which was 11 times higher. Conclusions These data show that even during a pandemic that highly affected mobility and economic activities and decreased air pollution around the world, complying with the new WHO Guidelines will demand a global strategical effort in the way we generate energy, move in and around the cities, and manufacture products.
