In this study, a finite element model of a tissue-mimicking, viscoelastic phantom with a stiffer cylindrical inclusion subjected to an acoustic radiation force (ARF) is presented, and the resulting shear waves through the heterogeneous media are simulated, ...
Unanchored steel tanks subjected to strong ground motion may experience rocking motion if the moment generated by the inertial mass of the content stored is greater than the resisting moment provided by the weight of the tank and its content. Rocking of th ...
Take-off and landing manoeuvres are critical for MAVs because GPS-based autopilots usually do not perceive distance to the ground or other potential obstacles. In addition, attitude estimates based on inertial sensors are often perturbed by the strong acce ...
The analysis of strong and weak motion recordings in existing structures is critical for understanding both the damaging process during earthquakes and their structural behavior. The time-frequency representation is one of the existing methods to get infor ...
AB: The accurate prediction of near-source strong-ground motions in future earthquakes is a major challenge for seismologists and earthquake engineers. Such a prediction is however difficult, partly because ground motions are highly variable while the reas ...
When an unanchored tank is subjected to strong motion, the impulsive mass of the contained liquid generates a moment which if strong enough could cause partial uplifting of the base plate. As the tank undergoes uplifting, the shell-base welded connection i ...
Seismic wave propagation in granular soils can induce large strain amplitudes in case of strong earthquakes. Seismic motions are irregular in frequency content and in amplitude, and have three different components in orthogonal directions. In this context, ...
Deriaz O, Najafi B, Ballabeni P, Crettenand A, Gobelet C, Aminian K, Rizzoli R, Gremion G. Proximal tibia volumetric bone mineral density is correlated to the magnitude of local acceleration in male long-distance runners. J Appl Physiol 108: 852-857, 2010. ...
The blade tip vortex of a full-scale MBB Bo 105 Helicopter is investigated experimentally under simulated hover flight conditions in ground effect by means of stereoscopic Particle Image Velocimetry. Based on the three-component velocity field of azimuthal ...
This paper summarizes collapse performance measures and the probabilistic basis for their development to assist in understanding of collapse behaviour of buildings and implementation of performance objectives in design and evaluation of buildings for colla ...
