Method of modifying the frequency response of a wooden article

, 2011
Disclosed is a method for modifying the frequency response of a wooden article by exciting the article with acoustic energy. Frequency response is the measure of a system\u27s spectrum response at the output due to a signal of varying frequency (but ...

Uncertainty propagation in locally damped dynamic systems

, 2012
In the field of stochastic structural dynamics, perturbation methods are widely used to estimate the response statistics of uncertain systems. When large built up systems are to be modelled in the mid-frequency range,perturbation methods are often ...

Assessment of transformer winding displacement faults by frequency response analysis

, 2010
According to the statistics of transformer accidents from 1995 to 1998, nearly 50% of the accidents were caused by short circuit, and the number is still increasing.
