Effects of vibrations,n buildings or may disturb the normal operation of machinery. Studies in this field refer to persons, buildings and machinery. Persons are the most sensitive to vibrations. Safe limits and vibration severity criteria are presented in the following.

Instrumentation for vibration measurement, (Fig. 5.2 b). These spectra describe how the input signal is altered when passing through the instrumentation system: the frequency components falling within the flat passband of the system remain unaltered, the others being attenuated and shifted in phase.

Providing Non-stop Service for Message-Passing Based Parallel Applications with RADICnterval. Fault tolerance and preventive maintenance are key issues in order to enlarge the MTTI (Mean Time To Interrupt). In this paper we present how RADIC, a architecture for fault tolerance, provides different protection levels able to avoid system interruptions and allows the performance of prev
