AMBIENT VIBRATIONAL ANALYSIS OF AURELIANA COLUMN
, 2014 The results of ambient vibration survey of Aureliana Column in Rome are shown. The objective of this analysis was the characterization of the dynamic behavior of the monument and the comparison with the results obtained with similar studies about 30 years ago, but with older instruments and data analysis methods.

The Hanging Column as a Dynamic Vibration Absorber
International Journal of Structural Stability and Dynamics, 2018 A simple mass–spring system with an attached hanging column is investigated. The problem is formulated and the frequencies obtained with an efficient initial value method. Under forced vibration, the amplitude of the mass may be greatly reduced by adding a hanging column.

In vivo measurements of spinal column vibrations.
The Journal of Bone & Joint Surgery, 1984Recent epidemiological studies have indicated high risk factors for persons exposed to vibrations. We measured the in vivo responses of the lumbar vertebrae and sacrum of five volunteers who were subjected to pure sinusoidal vertical vibrations in the seated position.

Column miniextractors with a vibrating nozzle
Theoretical Foundations of Chemical Engineering, 2010Vibrating minicolumns with low and high-frequency drives are suggested for the laboratory investigation of extraction processes. It has been experimentally determined that these apparatuses of up to 1 m in height and 20–50 ml in volume, depending on the physicochemical properties of fluid systems, can provide an efficiency of mass exchange ...

Studies of columns of beads under external vibrations
Physical Review E, 1994As a toy model for dissipative granular materials, we investigate a one-dimensional column of beads undergoing external vibrations. The analysis is both experimental and numerical. We display the crossover from a condensed to a fluidized state of the column; the parameters are the agitation, the number of beads, and the momentum restitution coefficient.
