amplitudes of seismic waves decrease with distance according to anelastic properties of the earth and geometrical spreading. the attenuation of ground-motion amplitudes in the frequency domain is an important problem in engineering seismology. it is of particular practical interest in the regions such as zagros (iran). the zagros fold- thrust belt, as a part of alpine- himalayan orogenic belt i...

ABSTRACT We explore nonlinear site effects in the new Japanese ground-motion dataset compiled by Bahrampouri et al. (2020). Following approach of Seyhan and Stewart (2014), we evaluate decrease soil amplification according to increasing corresponding ground motion on surface rock (VS30=760 m/s). To better predict associated with each record, take into account between-event variability motion, i...

In this work, rising of a single bubble in a quiescent liquid under microgravity condition was simulated. The related unsteady incompressible full Navier-Stokes equations were solved using a conventional finite difference method with a structured staggered grid. The interface was tracked explicitly by connected marker points via hybrid front capturing and tracking method. One field approximatio...

The ability to perform different tasks by a serial manipulator mounted on legged robots, increases the capabilities of the robot. The position/force control problem of such a robot in the stance phase with point contacts on the ground is investigated here. A target plane with known stiffness is specified in the workspace. Active joints of the legs and serial manipulator are used to exert the de...

The city of Ohrid is one the oldest settlements in western Balkans, exceptionally rich with archeological, architectural, and cultural sites, which must be protected from damage during future earthquakes by proper retrofitting strengthening old structures. To provide a sound basis for work, this paper, we describe amplitudes strong ground motion range probabilities being exceeded. We use Unifor...
