In some sense, the sine curve tracking the rise and fall of the angel cycle tends to follow behind the sine curve tracking the rise and fall of the broader business cycle.
Computations involving the motion of the interface are relatively fast as compared to "phase field" algorithms but, unlike many "curve tracking" methods, it is easy to detect and make topological changes.
To exemplify the possible use of such wind schedules in the design of control laws, model-based controllers are formulated in this paper that are capable of performing power curve tracking throughout all wind speeds, in contrast with commonly adopted approaches that use switching controllers to cover the various operating regimes of the machine.
The model-implied mortality curve tracks empirical mortality very closely when the denominators for the crude rates are not too small.
With a lead of six-tenths of a second after a first run of 46.65 seconds, Hays guided his sled down the 16-curve track without any problems, finishing in 46.61 seconds, the fastest run of the day.
His vision is still clear today: a dazzling array of ironwork and glass, crafted in the form of glazed canopies that radiate out from the gently curving track and wide platforms.
Broken and aged, Galileo sits toying with the brachistochrone apparatus, a curving track that allowed him to discover that the quickest path between two points may not be the shortest, or most obvious route.
Mr. Calatrava's first major commission, in 1982, was the Stadelhofen Railway Station in Zurich, a complex task that involved working in a hilly, built-up area alongside some 300 yards of curving track.
Both sets of (green, gray) curves track each other for times after 2100 LST.
As one would expect, there is some fluctuation in the curves, which decreases with increasing P, but for P ≥ 100 the curves track each other fairly closely.
