The numerical scheme is based on finite difference method. This program is also providing several boundary conditions. More particularly the Neumann, Dirichlet and Mur boundary conditions.

R. China. Full-waveform velocity inversion based on the acoustic wave equation in the time domain is investigated in this paper. The inversion is the iterative minimization of the misfit between ...

Fix collisions not being removed when a collider is parented to a rigidbody while in collision with it. Fix collisions not being added when the parent was removed while intersecting a (previously) ...

Calculate the mechanical advantage of the pulley system. Velocity ratio (VR) is the ratio of the distance moved by the effort to the distance moved by the load. In a pulley system, it is often ...

Calculate the overall gear ratio of the compound gear train. Calculate the transmission speed of the output gear. \(\text {velocity ratio} = \frac{\text{speed of driver gear}}{\text{speed of ...

Conceptually fine layering causes the so-called VTI (vertical transverse isotropy) anisotropy with a vertical symmetry and the effect is parametrized by the horizontal and vertical velocity ratio. It ...

2 Research Institute of the Hospital 12 de Octubre (“i+12”), Madrid, Spain Although there is no consensus as to whether exercise is beneficial during pregnancy, most studies report it poses no risk to ...

By comparing the results of our assessment to a hypothetical norm, we can quantify the language delay of the speaker with autism. Our assessment, the Stimulus Control Ratio Equation (SCoRE), is a ...
