An ellipse is a type of conic section: if a cone is cut with a plane which does not intersect the cone's base, the intersection of the cone and plane is an ellipse.
The shape of an ellipse is usually expressed by a number called the eccentricity of the ellipse, conventionally denoted e (not to be confused with the mathematical constant e).
The semi-latus rectum of an ellipse, usually denoted l (lowercase L), is the distance from a focus of the ellipse to the ellipse itself, measured along a line perpendicular to the major axis.

A sphere can also be defined as the surface formed by rotating a circle about its diameter.
If the circle is replaced by an ellipse, the shape becomes a spheroid.
For any natural number n, an n-sphere is the set of points in (n+1)-dimensional Euclidean space which are at distance r from a fixed point of that space, where r is, as before, a positive real number.

World line of the orbit of the Earth depicted in two spatial dimensions X and Y (the plane of the Earth orbit) and a time dimension, usually put as the vertical axis.
Note that the orbit of the Earth is an ellipse in space, but its worldline is a helix in spacetime.
In physics, spacetime is a model that combines 3-D space and 1-D time into a single construct called the space-time continuum (the 4th dimension).

Every star, therefore, describes an apparent orbit, which, if the line joining the sun and the star be perpendicular to the plane Abcd, will be exactly similar to that of the earth, i.e.
As the star decreases in latitude, this circle will be viewed more and more obliquely, becoming a flatter and flatter ellipse until, with A is zero latitude, it degenerates into a straight line (fig.

In physics, an orbit is the path that an object makes, around another object, whilst under the influence of a source of centripetal force, such as gravity.
A closed orbit has the shape of an ellipse (or in the limiting case, a circle).
The point where the orbiting body is closest to Earth is the perigee, called periapsis (less properly, "perifocus" or "pericentron") when the orbit is around a body other than Earth.

Most disambiguation is done by the generic ambiguity resolver, in generic_amb.h.
There are a few other ad-hoc disambiguation strategies here and there, such as for deciding between statements and declarations, and resolving uses of implicit int (when KandR support is enabled).
First, instantiation of template class declarations is required in order to disambiguate the AST, since a template class member can be either a type or a variable name, and that affects how a use of that name is parsed.

Interestingly, the result shows that a disambiguator may operate beneath the performance of a baseline algorithm, and still be useful for retrieval.
In addition, the improved disambiguation algorithm appears to be less sensitive to changes in the stoplist, and could be made to run faster than the previous system.

 Alternate Object Oriented Programming View
The key to the tension in the circle-ellipse ``dilemma'' is that an ellipse object can be mutated so that it becomes a circle, yet its type remains ellipse because the static type system cannot express the idea that an object's type can change over its lifetime while its identity remains constant.
The other is to allow mutation, but detect the case when an ellipse's properties indicate that it's really a circle and dynamically change its type to circle, taking care to add, delete and recompute any necessary properties to handle the representation change properly.
Encapsulation also gets in the way; obviously if we are going to handle the dynamic conversion of an ellipse to a circle, we have to know how to convert the properties of one to the other, and this means that the method for doing this will be quite "chummy" with both types.

If the baseline is taken parallel to the shorter of an ellipse's two diameters, a tall dome results, giving a sense of upward reach.

 13.4.1 Explicit interface member implementations (C# Language Specification)
This is particularly useful when a class or struct implements an internal interface that is of no interest to a consumer of that class or struct.
Explicit interface member implementations allow disambiguation of interface members with the same signature.
For an explicit interface member implementation to be valid, the class or struct must name an interface in its base class list that contains a member whose fully qualified name, type, and parameter types exactly match those of the explicit interface member implementation.
