21. Early fiber simulations employed particles which were rigid rods or prolate spheroids, whose equations of motion have analytical solutions. 22. "' Prolate spheroidal coordinates "'are a three-dimensional principal axes are equal in length. 23. 14 . " This article concentrates on the problem on an ellipsoid of revolution ( both oblate and prolate ). 24. These time constants can differ significantly when the axial ratio \ rho deviates significantly from 1, especially for prolate spheroids. 25. The DPSS ( discrete prolate spheroidal sequence ) or Slepian window is used to maximize the energy concentration in the main lobe. 26. In the prolate settlement there are several outbuilding and a renaissance bastion with a gate, into which the original driveway issues. 27. ;Prolate : This is an icosahedron elongated along the fivefold axis and is a common arrangement of the heads of bacteriophages. 28. Occasionally, after 11 or 12 hours of watching prolate spheroids bounce and soar, a game might even decide a national champ. 29. Its top section is a prolate spheroid, which exudes a blue glow and is approximately three times the size of an egg. 30. The ball used in rugby union, usually referred to as a rugby ball, is a prolate spheroid essentially elliptical in profile.
