The model of induction motor is considered in the fixed reference frame concerned with the stator.
This allows verification that the NEP values computed from the fixed reference station are representative of the whole Scheldt plume.
As suggested by Kasaj et al. [ 11], the cementoenamel junction or restoration margin was used as the fixed reference point.
The compass provides a fixed reference point to mark the start of each rotation.
The numbers of possible scales we analyzed are given by n = 59 and k = 4, 6, and 11; 59 was used rather than 60 because the octave is assumed as a component interval of all scales, and 4, 6 and 11 were used rather than 5, 7, and 12 because we treated the first note as a fixed reference point (i.e. a tonic).
Furthermore, the calculation of S b, r for all placements of the same read in a fixed reference tree can be done efficiently, because calculating the change between S b, r and S b', r where b and b' are adjacent branches of T, requires only a limited calculation involving local branch lengths [ 19, 20].
Even psychologists, who are more comfortable with survey data, say that the lack of a fixed reference point creates problems.
MEMS sensors are suitable for multipoint simultaneous measurements of an in-service steel bridge, because they do not require a fixed reference point and can be attached by magnets on the painted surface of the bridge.
Because the Earth's orbit, and hence the ecliptic, moves very little, it is a relatively fixed reference with respect to the stars.
The implications were undeniable: the idea of ether as a fixed reference frame through which light must propagate was coming undone.
