Two-dimensional lattice particle models have been used to simulate dynamic thrust faulting and its effects on near-fault ground motions. The lattice particle modeling approach has been demonstrated as an efficient way to model the dynamic rupture phenomena observed from a foam rubber experiment on dipping faults. We constructed a 42 dipping fault model to simulate near-fault ground motions unde...

The significance of stochasticity in the characteristics of the surface layers of a site to the resulting spatial variation of seismic ground motions and the seismic ground strains is investigated. For this purpose, an analytical site-specific model is developed. The model approximates the site topography by a horizontally extended layer with random characteristics overlying a half-space (bedro...

The unique atmospheric conditions present at sites such as Dome C on the Antarctic plateau are very favorable for high spatial resolution astronomy. At Dome C, the majority of the optical turbulence is confined to a 30 to 40 m thick stable boundary layer that results from the strong temperature inversion created by the heat exchange between the air and the ice-covered ground. To fully realize t...

The effects o f new Tubulicid R (a commerical cavity cleanser which contains 0,2 per cent disodium EOT A) on smear layer removal from ground and cavity dentine surfaces with and without mechanical agitation were de­ termined. None o f the surfaces displayed smear layer re­ moved scores greater than one. Although mechanical agi­ tation appeared to improve the smear layer removed properties o f n...

The onset of anomalous resistance in a layer on auroral field lines is shown to be accompanied by the excitation of an Alfvénic impulse (AI). The generated AI marks the transition of the global magnetosphere-ionosphere instability into an explosive phase with positive feedback. The spatial structure of this impulse both in space and on the ground has been described analytically and numerically ...

Abstract Ground Penetrating Radar (GPR) is one of a new instrument in the field survey that has emerge along with advancement world technology. The non-destructive technique (NDT) was introduced GPR able to be used assessing condition pavement structure and condition. This data can assess underground features thus detect any anomalies buried such as cable pipe. current very destructive cost lot...

Each PCB in the system should have at least one complete layer dedicated to the ground plane. Ideally, a double-sided board should have one side dedicated to ground and the other side for interconnections. In practice, this is not possible, since some of the ground plane will certainly have to be removed to allow for signal and power crossovers and vias. Nevertheless, as much area as possible s...

The interaction of a helicopter rotor with the ground in hover flight is addressed numerically using hybrid Eulerian–Lagrangian CFD model. When takes off or lands, its wake interferes ground. This interaction, depending on height-to-rotor diameter ratio, causes altering loading and performance as compared to unconstrained case gives rise development complex outwash flow field surrounding helico...
