spherical cap

The blue section of the illustration is also a spherical cap.

In geometry, a spherical cap is a portion of a sphere cut off by a plane.

Hence for a unit sphere the solid angle of the spherical cap is given as:

Its shape is that of a spherical cap, approximately twenty percent of the volume of what would have been the entire sphere."

Packing and Covering of Congruent Spherical Caps on a Sphere.

It can be thought of as a spherical cap with the top truncated, and so it corresponds to a spherical frustum.

Before again issuing from it, this spiral runs into a small cone with a concave base, that is turned downward in the shape of a spherical cap.

The small fraction of this volume where the intercellular bridge intersects the spherical caps was subtracted from the furrow cortex volume.

For the sphere, the problem is to construct all the circles (the boundaries of spherical caps) that are tangent to three given circles on the sphere.

It follows that the deleted neighborhood basis of given by the punctured spherical caps corresponds to the complements of closed planar disks .

The widespread species Itajahya galericulata has a roughly spherical cap of several overlapping spongy tissue layers with gleba sandwiched in-between.

It can be described as the union of a spherical cap and the cone formed by the center of the sphere and the base of the cap.

It has a structure that makes use of a special time in precast concrete decorated with grooves in the shape of spherical cap, who carry an unusually large and high arch.

One way to analyze the motion, once the hot gas has cleared the ground sufficiently, is as a 'spherical cap bubble', as this gives agreement between the rate of rise and observed diameter.

If the plane passes through the center of the sphere, so that the height of the cap is equal to the radius of the sphere, the spherical cap is called a hemisphere.

A sessile drop whose largest dimension is smaller than the capillary length, for example, will take the shape of spherical cap, which is the solution to the Young-Laplace equation with gravity completely absent.

Here the heat from below sought an exit, working at the th'in spherical cap of ice, seeping upward, finding an opening here, a weakness there, and at last breaking onto the surface in short-lived victory.

The fulcrum of almost all wobble boards is a semi-sphere or smaller spherical cap (or a shape that is approximately such) whose flat side is attached to the center of the board's underside.

For instance, the first chamber of Bactroceras resembles that of other Ordovician orthocerids, such as Archigeisonoceras and Hedstroemoceras: it is about 10 mm in diameter, and is short, forming a spherical cap.

The portion of the furrow cortex flanking the intercellular bridge, which extend upwards to the flexion point of the curvature of the main cell body, was modeled as a difference of inner and outer spherical caps.

To do this, we modeled the cell in three shapes: a sphere at early anaphase, a cylinder with two spherical caps at late anaphase, and a dumbbell with spherical cap domains connected by a cylindrical intercellular bridge.

"The spherical cap of the small cone is of platinum, so as not to melt by the action of the cylinder and blow-pipe, for the latter are placed upon the bottom of the iron tank in the midst of the helicoidal spiral, and the extremity of their flame will slightly touch the cap in question.

Over 2200 years ago Archimedes proved, without the use of calculus, that the surface area of a spherical cap was always equal to the area of a circle whose radius was equal to the distance from the rim of the spherical cap to the point where the cap's axis of symmetry intersects the cap.
