Control of relative vibration between flexible appendages using passive and semi-active isolation
(Elsevier, 2017-12)
Relative vibration between two flexible subsystems can be detrimental to the performance of many engineering applications, such as optics-based instruments, machine tools, or adjacent industrial structures sharing piping. ...
Vibration radiation from buried plastic water pipes: An experimental investigation at the ground surface
(2012-01-01)
'Mapping the Underworld' is a research initiative that is seeking to address the consequences arising from an inability to consistently locate the buried utility service infrastructure without resorting to extensive ...
Recent Advances in Shock Vibration Isolation: An Overview and Future Possibilities
(2019-01-01)
Mechanical shock is a common problem that is present in many situations, such as ground motion, blast, explosions, crash, and impact. The development of passive, active, or adaptive control and isolation strategies for ...
Aplicação de métodos estatísticos multivariados na avaliação de vibrações sísmicas
(2016-03-01)
The present paper analyses multivariate statistical methods applied to evaluate blasting seismic vibration in quarries. Principal components analysis and multigroups discriminate analysis were used. Blast pattern and ...
Digital signal processing for self-vibration monitoring in grinding: A new approach based on the time-frequency analysis of vibration signals
(2019-10-01)
The occurrence of chatter can generate parts outside the dimensional and geometric tolerances or even cause irreversible damage, such as changes to the hardness and surface roughness of the ground part. The objective of ...

Radiation thermo-chemical models of protoplanetary discs IV. Modelling CO ro-vibrational emission from Herbig Ae discs
(EDP Sciences, 2013)
Context. The carbon monoxide (CO) ro-vibrational emission from discs around Herbig Ae stars and T Tauri stars with strong ultraviolet
emissions suggests that fluorescence pumping from the ground X1Σ+ to the electronic A1Π ...
Molecular vibrational constants and chemical bonding in five-membered heteratomic compounds
(1985)
By means of the force field and mean amplitudes of vibration of furan, thiophene, selenophene and tellurophene molecules, we have concluded that the ground-state aromaticity order in the series is thiophene > tellurophene ...
Optimal laser control of molecular photoassociation along with vibrational stabilization
(Elsevier B.V., 2011-01-07)
This work explores the optimization of laser pulses for the control of photoassociation and vibrational stabilization. Simulations are presented within a model system for the electronic ground-state collision of O + H. The ...
