Steiner point = bc / (b2 − c2) : ca / (c2 − a2) : ab / (a2 − b2) = the nonvertex point of intersection of the circumcircle with the Steiner ellipse.
The Bald Eagle was a common symbol used in this style, with the ellipse a frequent architectural motif.
The Ellipse was thus further developed in collaboration with Thales as a modular platform for civilian and military missions with different equipment systems including day and night vision, rocket launching, and on-board communication systems.
The park contains several structures like the Field of Mars (Campos de Marte) — also known as The Ellipse (La Elipse), for its shape — where every September 19, the military parade takes place.
HL7 CDA (Clinical Document Architecture) also has a subset of mechanisms similar to (and intended to be compatible with) DICOM for referencing image-related spatial coordinates as observations; it allows for a circle, ellipse, polyline or point to be defined as integer pixel-relative coordinates referencing an external multi-media image object, which may be of a consumer rather than medical image format (e.g., a GIF, PNG or JPEG).
A limited edition of Ellipse-Nelvana's The Adventures of Tintin TV cartoon series was released as its HMV exclusive in Europe by Anchor Bay Entertainment.
Tissot’s indicatrix (Tissot indicatrix, Tissot’s ellipse, Tissot ellipse, ellipse of distortion) is a mathematical contrivance presented by French mathematician Nicolas Auguste Tissot in 1859 and 1871 in order to characterize distortions due to map projection.
In geometry, an unduloid, or onduloid, is a surface with constant nonzero mean curvature obtained as a surface of revolution of an elliptic catenary: that is, by rolling an ellipse along a fixed line, tracing the focus, and revolving the resulting curve around the line.
