Abstract: When an extended structure is excited at frequencies above the resonance of its lowest modes, spatial variations in the mean square response occur since the mode shapes are functions of the ...

Abstract: The interaction of structures and sound fields frequently involves many degrees of freedom of each participant in a complicated interaction process. In one way or another, statistical or ...

Abstract: Cepstral Analysis is an example of nonlinear filtering that has been applied to extracting the properties of transmission path and source characteristics in acoustics. To see why this is so, ...

Abstract: Dynamic excitations in machines and structures may lead to a form of wear caused by the phenomenon of fretting, which may cause premature mechanical or structural failure. Fretting-wear has ...

Abstract: The use of vibration signals produced by the operation of a machine to control its operations and detect developing faults is appealing because of the ruggedness of vibration sensors and their ...
