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. ...
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 ...
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 ...
Image analysis to obtain the vibration amplitude and the residence time distribution of a vibro-fluidized dryer
(Inst Chemical EngineersRugbyInglaterra, 2004)
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 ...
Detection of buried pipes using a shear wave ground surface vibration technique
(2012-12-01)
A major UK initiative, entitled 'Mapping the Underworld', is seeking to address the serious social, environmental and economic consequences arising from an inability to locate the buried utility service infrastructure ...
The Role of Proprioception in the Sagittal Setting of Anticipatory Postural Adjustments During Gait Initiation
(2015-12-01)
Purpose. Previous studies have studied the role of proprioception on the setting of anticipatory postural adjustments (APA) during gait initiation. However, these studies did not investigate the role of proprioception in ...
Point vibration measurements for the detection of shallow-buried objects
(2012-09-04)
A major UK initiative, entitled 'Mapping the Underworld', is seeking to address the serious social, environmental and economic consequences arising from an inability to locate accurately and comprehensively the buried ...
Vibrational effects on SrTiO3 Ti 1s absorption spectra studied using first-principles methods
(Iop Publishing, 2008-12)
We analyze the vibrational effects on the Ti 1s excited states in cubic SrTiO3 and related pre-edge x-ray absorption fine structure using first-principles methods. Ground-state, total-energy and electron-core hole ...
Statistical methods applied to the analysis of blasting vibrations in a diabase quarry in the city of Campinas, (SP) Brazil
(Int Soc Explosives Engineers, 2002-01-01)
Statistical methods of multiple regression analysis, trend surface analysis and principal components analysis were applied to seismographic data recorded during production blasting at a diabase quarry in the urban area of ...
