Sentence examples for ellipsoid from inspiring English sources

In the shape of an ellipsoid about the size of three refrigerators, it can swim in any direction and is unlikely to snag on obstacles.

Eighteenth-century architects created a fad for whispering galleries such as in the U.S. Capital and in St . Pauls Cathedral in London—in which a whisper at one focus of an ellipsoid (an ellipse rotated about one axis) can be heard at the other focus, but nowhere else.

If two axes are equal, say a = b, and different from the third, c, then the ellipsoid is an ellipsoid of revolution, or spheroid (see the figure), the figure formed by revolving an ellipse about one of its axes.

This surface is called an ellipsoid if a, b, and c are positive.

Results show that the geoid is irregular; in places its surface is up to 100 metres higher than the ideal reference ellipsoid and elsewhere it is as much as 100 metres below it.

The ellipsoid joint also has two types of movement but allows opposition movement only to a small degree.

This model can, thereafter, be used to match any subsequent image, or part thereof.EBGM considers the head as a union of two ellipsoids: one whose main axis is vertical, and runs from forehead to chin; the other whose main axis is horizontal, and runs from tip of the nose to the back of the cranium.

It contains solutions to a number of geometric problems, shows that stable figures for a homogeneous rotating fluid mass are the ellipsoids of revolution, and gives for the first time the correct theory for distinguishing between maxima and minima in general (see calculus of variations), pointing out the importance of the distinction in the theory of the multiple points of curves.

Rapid rotation of some stars flattens their shapes into ellipsoids.

In similar manner, Archimedes worked out the volumes and centres of gravity of spherical segments and segments of the solids of revolution of conic sections paraboloids (see the figures of an and a ), ellipsoids (see the figure), and hyperboloids.

By the time she left Dusseldorf, in 1977, to travel to America on a study grant, she had begun making large-scale sculptures ("ellipsoids" and "hyperbolos") in lacquered wood.
