Computer graphics animation often lacks interaction between rigid object and granular material. In this paper, we propose a method for the deformation of the ground surface that consists of granular material when it penetrated by a rigid body object in motion. Meanwhile, the motion of the rigid object is also affected due to the collision with the ground surface. Our simulation model concerns: ...

due to the tilt of the platform carrying the synthetic aperture radar(sar), the image formation algorithms(like rda) can not yield to good quality images from the ground. therefore, it is convenient to use a two-step approach for motion compensation in image formation algorithms. in this paper, using an approximated linear model for the motion error and the impact of range compression step of r...

The widespread application of the hybrid empirical method (HEM) has made it a viable approach for developing ground motion prediction equations in regions where there are few strong motion recordings but there are ample weak motion data from small-magnitude earthquakes. The HEM uses empirical estimates of ground motion in one region (the host region) to provide estimates of ground motion in ano...

Dynamic contrast-enhanced MRI of the breast (DCE-MRI) is widely used for detection and quantification purposes of breast cancer. The particular acquisition procedure of DCE-MRI over time leads to motion artifacts which distort analysis results. In this work we examine two criteria for a segmentation approach to separate areas affected by motion artifacts from properly perfused regions. By appli...

the near field ground motions have a high amplitude pulse like at the beginning of the seismogram which are significantly influenced by the rupture mechanism and direction of rupture propagation. this type of ground motion cause higher demands for engineering structures and its response spectrum is dramatically different than far field spectra. tabriz is one of the ancient cities in azerbaijan ...

worldwide networks of seismic recording instruments mostly record only translational ground motion in two or three orthogonal directions. rotational component of earthquake is not commonly recorded. several theories are available to estimate a torsional component from recorded translational components of ground motion. in this paper detailed investigations are made to study the relative perform...

-The acceleration record of an earthquake ground motion is a nonstationary process with both amplitude and frequency content varying in time. The paper presents a general procedure for the analysis and simulation of strong earthquake ground motions based on parametric ARMA models to be used in computing structural response. Some computational results obtained in the analysis and simulation of g...

This paper investigates the strategies used during the human sit to stand movement. The analysis was carried out by means of the 3D videographic examination methods and a posturographic platform. The joint trajectories corresponding to the motion were reconstructed using the Humanoid Motion Analysis and Simulation (HuMAnS) toolbox developed at INRIA-Grenoble. The reliability of the dynamic mode...
