Ultrasound

Ultrasound

Surhone, Lambert M. / Timpledon, Miriam T. / Marseken, Susan F.
Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Although this limit varies from person to person, it is approximately 20 kilohertz (20, 000 hertz) in healthy, young adults and thus, 20 kHz serves as a useful lower limit in describing ultrasound. The production of ultrasound is used in many different fields, typically ...

Rail Transport Modelling Scales

Rail Transport Modelling Scales

Surhone, Lambert M. / Timpledon, Miriam T. / Marseken, Susan F.
Rail transport modelling utilises a variety of scales (ratio between the real world and the model) to ensure scale models look correct when placed next to each other. Model railway scales are standardized worldwide by many organizations and hobbyist groups. Some of the scales are recognized globally, while others are less widespread and, in many cases, virtually unknown outside their ...
