Abstract: Most conventional blood flow estimation methods measure only the axial component of the blood velocity vector. In this study, we developed a new method for two-dimensional (2-D) velocity ...

Abstract: Doppler frequency only reveals the radial component of a target's velocity. In order to actually measure the true velocity vector of an object, at least two targets originating from the same ...

Any vector can be expressed as a sum of a number of other vectors. The vectors which are summed are called the components of the original vector. When you want to add and subtract two dimensional ...

The ability of primates to sense the direction and speed (together, the velocity) of moving objects depends on an elaborate sequence of computations that have been investigated in psychological, ...

V(:,:,:)=(u0/k)*log((Z(:,:,:)-d)/z0).*sin(ekman*(Z(:,:,:))); %x component of wind velocity U(:,:,:)=(u0/k)*log((Z(:,:,:)-d)/z0).*cos(ekman*(Z(:,:,:))); %y component ...
