Caption: Figure 9: RMSE versus angular separation
with the fixed SNR 10 dB and number of snapshots 500 for coherent sources.
Simulation results reveal that the proposed QSWL GSC has the better performance in small angular separation
and the robustness to DOA mismatch.
We observe that, for scenario of single source or large angular separation
, the accuracy of sSSR-SS and sSSR-AC is similar to that of [l.sub.1]-SVD and MUSIC, while for scenario of small angular separation
, the accuracy of our methods is slightly lower than that of [l.sub.1]-SVD, yet much higher than that of MUSIC.
Due to the equal angular separation
of each segment, the motor shaft is presented with minimal variation in torque load with respect to its angular position.
In 2008 the angular separation
is closer to 42 arcminutes, and it will be after 2060 before the separation is under 30 arcminutes (0.5[degrees]).
The maximum angular separation
between Venus and the Sun (as seen from Earth) is obtainable by direct observation at the relevant time of year:
But on the 24th the planet reaches greatest elongation (largest angular separation
) from the Sun and sets about 1 1/2 hours after sundown.
8 Venus at greatest morning elongation (maximum angular separation
from the sun in the sky)--see Mars article.
Intensity differences will be minimal only when the angular separation
of the arms is small or when a source is located along the axis bisecting the array.
This increased distance indicates a change in their angular separation
as viewed from the earth.
(4) We conclude that by performing the user scheduling scheme via 3D angular separation
, a significant system sum rate gain can be achieved, which ensures the promising future of 3D space utilization in interference management.
Meanwhile, the term "greatest elongation" is itself ambiguous, as this might mean either the greatest difference in right ascension or the greatest angular separation
. For Venus the time difference between the two can be up to 15 hours.
Missing from the sequence is the moon Ganymede, one of the four Galilean moons that was outside Hubble's field of view and too far from Jupiter in angular separation
to be considered part of this conjunction.
