[null,null,null,"Sommario/riassunto","This book, published by Carl Johannes Fuchs in 1910, examines the expansion of municipal activities in Halle, Germany, and abroad. It provides a comprehensive analysis of various city-operated institutions and services such as the Sparkasse (savings bank), municipal pawnshop, slaughterhouse, theater, and utilities including gas and waterworks. The text highlights the socio-economic transformation of Halle from a university town to an industrial and commercial hub in the late 19th and early 20th centuries. The book is intended for scholars "]

[null,null,null,"Sommario/riassunto","This book focuses on the low-frequency oscillation between EMUs and traction networks in high-speed Railways. As the power source of high-speed trains, the traction network's power performance directly affects the safe and stable operation of the train. However, the low-frequency oscillation between EMUs and traction networks will fluctuate voltage or current, resulting in poor power quality, electrical device failure, and even interruption of traction power. Therefore, it is important to reveal the mechanism of low-frequency oscillation and propose suppression strategies. This book systematically shows the newest research results "]
[{"$nulls":4},"of analysis and suppression of low-frequency oscillation between EMUs and traction networks in high-speed railways, especially in the modeling methods of vehicle-grid systems and suppression strategies for low-frequency oscillation. These methods or strategies can provide important references and help for researchers, scholars, and engineers on traction power technology in high-speed railways. The main contents include the overview of low-frequency oscillation between EMUs and traction networks, the introduction of main modeling methods for vehicle-grid systems, especially single-phase rectifiers, the line-side converter control algorithms in vehicles for the suppression of low-frequency oscillation, the traction substation power compensation strategies for the suppression of low-frequency oscillation, etc."]
