Features of the Modern Protectionism of the US and the EU towards Russia by A. A. Sidorov

“…The measure will affect important positions of the Russian exports – cement, electricity, fertilizers, iron & steel and aluminum. The mechanism can be considered an attempt to make up for the EU’s lack of natural competitive advantages in mineral raw materials and to impose its vision of economic policy goals on the rest of the world.In conclusion, the author highlights features of American and European protectionism towards Russia – active employment of the role of the state in the economy factor as well as environmental factor as pretexts for introducing or tightening restrictive measures.The main ways of Russia’s response to new challenges can be the use of the WTO platform in cooperation with other countries, the search for new economic levers in relations with the partners (including application of trade defence measures), the detection of possible market distortions in the EU and the US for possible use in EAEU investigations.…”

Damage Identification in Large-Scale Structures Using Time Series Analysis and Improved Sparse Regularization by Huihui Chen, Xiaojing Yuan

“…The proposed method has been validated based on a numerical continuous rigid frame bridge and an experimental steel truss bridge. Compared to the moth-flame optimization (MFO) algorithm and traditional regularization methods, for both noise-free and noise polluted data, the iteration curves illustrate that the proposed method can achieve convergence within about 200 iterations, while the MFO algorithm is always trapped into local optima; meanwhile, the traditional regularization method needs more iterations or even cannot meet the preset tolerance. …”

Comprehensive Treatment of Curved Section Abnormal Noise for Elevated Urban Rail Transit Line by LIU Yuhang, ZHOU Changsheng, LIU jinhui, ZHOU Hualong, CHEN Sai

“…［Result & Conclusion］ The rail top coating device has little influence on the overall wheel-rail noise level, but can effectively suppress the squealing noise. Grinding steel rail has significant effect on reducing wheel-rail noise, and the short-wave corrugation in the curved section is eliminated. …”
