This monograph covers the area of vector control of three-phase AC machines, in particular induction motors with squirrel-cage rotor (IM), permanent excited synchronous motors (PMSM) and doubly-fed induction machines (DFIM), from the viewpoint of the practical design and development. Main focus is on the application of the IM and the PMSM in electrical drive systems, where the method of the field-orientated control has been successfully established in the practice, and on the use of the grid voltage orientated controlled DFIM in the wind power plants.
After a summary of the basic...

What does it mean when a city of 180,000 people has more than 5,000 women working as prostitutes? This question frames Vu Trong Phung's 1937 classic reportage Luc Xi. In the late 1930s, Hanoi had a burgeoning commercial sex industry that involved thousands of people and hundreds of businesses. It was the center of the city's nightlife and the source of suffering, violence, exploitation, and a venereal disease epidemic. For Phung, a popular writer and intellectual, it also raised disturbing questions about the state of Vietnamese society and culture and whether his country really was...
