The variation in tilt, as represented by the pitch and roll of the codend, decreased significantly with towing speed, whereas the turbulence rate increased with the rate of variation in tilt.
This is because the variation of tilt angle changes the amount of solar radiation reaching the collector surface.
Open image in new window Figure 6 Methanol flow rate variation with tilt angles under 500 W/m 2 average solar intensity.
At 23.0 million years ago, eccentricity dropped to low levels and variations in tilt nearly disappeared.
We report the first classification results for daily variations of tilt angles (normal and trigonometric ones) in sunspot groups (SG) and active (AR) regions in the cycle 23.
Although the orbits at MEA and FPS have some minor deviations from a straight line, and variations of tilt direction within a few degrees are conceivable, the comprehensive tilt motions are well represented by the linear tilt vectors shown in Fig. 4.
More specifically, variations in tilt, illumination and signal quality pose a significant challenge.
Also constraints on the rate of variation of the tilt corrections are taken into account.
(b) Temporal variation of the tilt (bottom), its velocity (middle), and its acceleration (top).
Yet, due to the variation in pelvic tilt and the variation between patients this may also be a challenge in clinical studies.
