Ground Plane Motion Parameter Estimation for Non-circular Paths [PDF]
Procedings of the British Machine Vision Conference 1992, 1992 A method of motion parameter estimation for AGV’s is developed based on a new trajectory constraint algorithm. It is assumed that the vehicle will follow a circular path over the vision sampling interval. The algorithm has been found to be more effective and consistent than least squares estimators when the motion obeys the trajectory constraint ...

Machine learning based ground motion site amplification prediction
Frontiers in Earth Science, 2023 Site condition impact on seismic ground motion has been a complex but important subject in earthquake hazard analysis. Traditional studies on site amplification effect are either based on site response via wave propagation simulation or regression ...

Correlation between macroseismic intensities and seismic ground motion parameters
Annals of Geophysics, 1997 We propose correlation relations between the macrosesimic intensity felt in Italy and displacement, velocity, acceleration, design ground acceleration obtained from synthetic seismograms modelling the ground motion generated by past seismicity.

Energies, 2022 After the Fukushima nuclear accident in Japan, whether the structural safety of the nuclear power plant (NPP) can be guaranteed under an earthquake has been of wide concern. Automatic seismic trip systems (ASTS) have been deployed in NPPs.

Estimates of Running Ground Reaction Force Parameters from Motion Analysis [PDF]
Journal of Applied Biomechanics, 2017 We compared running mechanics parameters determined from ground reaction force (GRF) measurements with estimated forces obtained from double differentiation of kinematic (K) data from motion analysis in a broad spectrum of running speeds (1.94–5.56 m⋅s–1).
