Ultrasonic Processes and Machines: Dynamics, Control and Applications

V. K. Astashev, V. I. Babitsky, «Ultrasonic Processes and Machines: Dynamics, Control and Applications»
Springer Berlin Heidelberg | ISBN: 3642091245 | 2009 | PDF | 344 pages | 8.61 MB

“

This work presents the foundations of dynamic and control for ultrasonic processing systems.This book considers ultrasonic systems as special vibratory machines that function by exploiting nonlinear dynamic processes. Recommendations are given for designing and tuning ultrasonic machines. The ultrasonic machines analysed are predominantly concerned with the processing of solids. Applications include: ultrasonic erosion, ultrasonic hardening, ultrasonic welding, ultrasonically assisted plastic deformation, ultrasonically assisted turning, and ultrasonically assisted drilling.

Ultrahigh-Speed Optical Transmission Technology

“

Ultrahigh-speed optical transmission technology is a key technology for increasing the communication capacity. In optical fibre networks, the number of wavelength channels and the bit rate per wavelength channel, i.e. the TDM (Time Division Multiplexing) bit rate, determine the transmission capacity. Currently, TDM bit rates of more than 40 Gbit/s require optical signal processing (Optical Time Division Multiplexing, OTDM). OTDM bit rates of up to 1.2 Tbit/s have already been reported. The devices developed for ultrahigh-speed optical transmission are not limited to communication applications only. They are key devices for high-speed optical signal processing, i.e. monitoring, measurement and control, and will thus give a wide technological basis for innovative science and technology. All these aspects of ultrahigh-speed optical transmission technology are described in detail in this book.
