The effectiveness of the gyroscopic effect for controlling structural vibrations
(Taylor & Francis Ltd, 2021-07)
It is well known that seismic and wind induced vibration is an important issue in structural performance. To mitigate the problem of structural vibrations, many methodologies have been proposed and implemented. In this ...
Blood-pressure–waveform monitoring without interruptions due to changes in arterial compliance: The use of the vibrational and volume-clamp methods
(Elsevier, 2021-11)
The arterial–blood-pressure (ABP) waveform can be monitored by the volume-clamp method. The photoplethysmography (PPG) signal is measured and clamped at maximum arterial compliance (PPGcmax) by controlling the external ...
Separation of Frequency Coexisting Vibration Signals in Wind Turbines Gearboxes
(Universidade Federal de Santa Maria. Programa de Pós-Graduação em Engenharia Elétrica, 2018-10-21)
In this paper, a method for separation of vibration signals coexisting in the same frequency bin and coming from different mechanicals pieces is presented. A blind source separation method for vibration signals in gearboxes ...
Analytical, numerical and experimental studies on the Semi-Active Friction Tendon
(Elsevier, 2017-09)
For controlling vibrations, a Semi-Active Friction Tendon (SAFT), which consists of a semi-active friction damper and an auxiliary spring that are linked to the structure by a cable, is studied experimentally, numerically ...
Optimum viscoelastic absorbers for cubic nonlinear systems
(Sage Publications Ltd, 2014-07)
Dynamic vibration absorbers are efficient devices used in vibration and noise control of several mechanical systems. In recent years, some studies about these control devices comprising systems with nonlinear characteristics ...
Electronic coherences and vibrational wave-packets in single molecules studied with femtosecond phase-controlled spectroscopy
(Royal Society of Chemistry, 2011-01)
Employing femtosecond pulse-shaping techniques we investigate ultrafast, coherent and incoherent dynamics in single molecules at room temperature. In first experiments single molecules are excited into their purely electronic ...
