VTI (8) dm

he citation in Figure 1 is not from a recent visitor in Rome, but from the Roman author Martial some 2000 years ago. Anybody who has seen Roman roads that still exist or the streets of old Pompeii can easily imagine the noise created by the wagons rolling down these uneven streets. This sound is the ancient form of tire/road noise. Today’s tire/road noise is a matter of concern. In fact, it is ...

Traffic Generation for the Vti Driving Simulator

Driving simulators are often used in a type of experiments where the result may depend on traffic conditions. One example is the evaluation of cellular phones and how they affect driving behavior. It is clear that the ability to use phones during driving depends on the amount of traffic, and that realistic experiments in driving simulators therefore must include surrounding traffic. This paper ...

Elastic wave-mode separation for VTI media

Elastic wave propagation in anisotropic media is well represented by elastic wave equations. Modeling based on elastic wave equations characterizes both kinematics and dynamics correctly. However, because P and S modes are both propagated using elastic wave equations, there is a need to separate P and S modes to obtain clean elastic images. The separation of wave modes to P and S from isotropic...
