Lubrication State Recognition Based on Energy Characteristics of Friction Vibration with EEMD and SVM by Hai-jie Yu, Hai-jun Wei, Jing-ming Li, Da‐ping Zhou, Li‐dui Wei, Hong Liu

“…The experimental results show that the frequency band energy characteristics of friction vibration signals are different under different lubrication states. Based on this, a lubrication state recognition method with ensemble empirical mode decomposition (EEMD) and support vector machine (SVM) was proposed. …”

Modeling the Spatial Correlations among Energy Consumption, Economic Growth, and the Ecological Environment by Feng Zhao, Yi Sun, Jie Zhang, Pingping Sun

“…The results show that (1) there are spatial correlations among energy consumption, economic growth, and the ecological environment in China’s provinces, and there are obviously different agglomeration areas in spatial distribution; (2) energy consumption, economic growth, and the ecological environment level show different growth trends, and the differences between different provinces in provincial units are shrinking; and (3) regarding energy consumption, the spatial impact of economic growth on the ecological environment is obvious, and there are obvious “path dependence” characteristics in the spatial distribution and positive correlations. …”

Assessing the COVID-19 Lockdown Impact on Global Air Quality: A Transportation Perspective by Meina Zheng, Feng Liu, Meichang Wang

“…Using daily air pollution data between 1 January and 31 December 2020, covering 596 major cities in 77 countries, we analyzed the data with a generalized difference-in-differences approach. The results show that lockdown restrictions reduced global concentrations of NO₂ by 21~35%, PM₁₀ by 14~26%, PM_2.5 by 9~18%, CO by 6~16%, and SO₂ by 5~16%, while the O₃ concentrations increased by 15~29% under eight specific lockdown measures. …”
