If the angles around the on-axis angle have a similarly smooth response, then it isn’t as critical that the speaker is listened to with ears at the same level. Diagonal view of a waterfall plot ...

Now, the dot product of N and (0,0,1) should be the cosine of the angle between the two vectors. Formulas for both the dot and cross product of 3d vectors are easily found.

CASTER. Understanding steering axis inclination makes it easier to understand caster, since they both have somewhat the same effect. Caster is the angle formed by a line through the ball joint ...

Angle alpha is the difference between the center of the limbus and the visual axis (Figure 1). Figure 1. Patient with high angle alpha (LSDist = angle alpha, 0.75 mm).

If you want to listen to satellites, you have to be able to track them as they pass over the sky. When I first started tracking amateur satellites, computing the satellite’s location in the s… ...

The ebb and flow of seasonal change is linked to the angle of the planet’s rotational axis, and over geologic time, a wandering axis could affect climate on a global scale, said Surendra ...

Over the last 60 years - Optical Surfaces has established itself as a world leading producer of high precision off-axis parabolic mirrors. Benefiting from a highly skilled team of engineers and ...

A highly directional speaker is one where the sound emission is contained in a narrow beam. It projects sound outward in a very narrow angle, so anyone who is not near the on-axis angle for the ...
