Both the tilt angle from the vertical and the azimuth angle of each antenna are fixed when the system is set up.
32.
This makes the pole want to lean slightly toward track center and stabilize at track center where the tilt angle is exactly vertical.
33.
For the special case of circular polarization, the axial ratio equals 1 ( or 0 dB ) and the tilt angle is undefined.
34.
Later Rosalind Franklin and Raymond Gosling have carried out their own geometrical reasoning and presented an approximative equation for the fiber tilt angle ?.
35.
In a protein sample with a well-defined orientation, the tilt angle of the probe can be quantitatively determined, in real space and real time.
36.
This, together with full-span leading edge and trailing edge flaps which were programmed with wing tilt angle, ensured that the wing was never stalled.
37.
This made the tilting of heavy cameras considerably easier and if correctly mounted a camera could be left at any tilt angle without lock off.
38.
A variant on this design is the use of arrays, whose tilt angle can be adjusted twice or four times annually to optimise seasonal output.
39.
When the tilt angle is low, less sunlight hits the high latitudes of the Northern Hemisphere in summer, less ice melts and ice sheets expand.
40.
When the train rounded a bend, the centrifugal forces caused the car body to swing out like a pendulum, reaching the proper tilt angle naturally.
