Integrated compaction control based on the motion behavior of a deep vibrator
, 2021Deep vibro compaction (vibroflotation) is a widely-used ground improvement technique in granular soils. During the compaction process, the vibrator body is in constant interaction with the compacted soil.

Modeling of energy transfer and parameter effects on it of a vibrator-ground system
Advances in Structural Engineering, 2020The amount of energy transferred to the ground truly represents the performance of the seismic vibrator. So, it is crucial to investigate the transfer of energy in the vibrator-ground system and how parameters affect it.

Coupled Eulerian Lagrangian based numerical modelling of vibro-compaction with model vibrator
, 2020The use of field experience and empirical relations for the design of a vibro-compaction encourages the development of the understanding of vibratory compaction for granular material. Field measurements are difficult to conduct in homogeneous loose sands,

Modeling of nonlinear interaction and its effects on the dynamics of a vibrator-ground system
Soil Dynamics and Earthquake Engineering, 2020The nonlinear interaction between a vibrator and the ground is one of the main sources of signal distortion in land exploration. So, it is crucial to describe this nonlinear interaction and study how it affects the outgoing wave radiated by the vibrator.

The Journal of Chemical Physics, 1970
The vibrational relaxation of a system of anharmonic oscillators with high initial vibrational energy into a low-temperature heat bath was studied. It was assumed that the vibration–vibration quasisteady population distribution was instantly established, and during the longer time scale the level population distribution was controlled by a continuous ...

Vibrational anharmonicity and multilevel vibrational dephasing from vibrational echo beats
The Journal of Chemical Physics, 1997Vibrational echo experiments were performed on the IR active CO stretching modes (∼2000 cm−1) of rhodium dicarbonylacetylacetonate [Rh(CO)2acac] and tungsten hexacarbonyl [W(CO)6] in dibutylphthalate and a mutant of myoglobin-CO (H64V-CO) in glycerol–water using ps IR pulses from a free electron laser.

A novel adaptive control algorithm for the rejection of harmonics in a standard vibrator
Journal of Vibration and Control, 2020Because of the nonlinear factors in the standard vibrators, the output waveform of the vibrators is usually distorted, especially in the low-frequency band.
