Unmeasured disturbances in chemical processes are often not stationary and frequently have a time-correlated, continuous-time (CT), stochastic behavior. The common way of addressing this type of disturbance is to treat it discretely as a noise component of the output. Not only can this treatment lead to inaccuracy caused by a discrete approximation of CT noise, but it requires a constant sampli...

The paper describes methodology of experimental diagnostics examining the influence of small home appliances in operation resulting in the injection of impulse noise into local communication lines. The most important result of practical experiments is a data bank of disturbing impulses that will serve for defining of impulse noise model. Keywords–impulse noise; communication lines; local loop; ...

In this paper, two Piezo-Based Rotating Inertial Actuators (PBRIAs) are considered for the suppression of the structure-borne noise radiated from rotating machinery. As add-on devices, they can be directly mounted on a rotational shaft, in order to intervene as early as possible in the transfer path between disturbance and the noise radiating surfaces. generate the appropriate actuation signals...
