To reflect this change, the Chief of Naval Operations changed the name of Corry Field to Naval Technical Training Center Corry Station In 1973, NTTC Cory Station was among the first Navy technical schools to be accredited by the Southern Association of Colleges and Schools which certified that students could receive college-level credit for ...
Sigsbee Park, also known as Dredgers Key, is an island about half a mile (800 m) north of Key West island in the lower Florida Keys; administratively it is within the City of Key West, Florida, United States. [1] It is connected to the island of Key West by Sigsbee Road. The island and causeway are part of the Key West Naval Air Station. It is ...
A hexameter line can be divided into six feet (Greek ἕξ hex = "six"). In strict dactylic hexameter, each foot would be a dactyl (a long and two short syllables, i.e. – u u), but classical meter allows for the substitution of a spondee (two long syllables, i.e. – –) in place of a dactyl in most positions. Specifically, the first four ...
Note: This page uses common physics notation for spherical coordinates, in which is the angle between the z axis and the radius vector connecting the origin to the point in question, while is the angle between the projection of the radius vector onto the x-y plane and the x axis. Several other definitions are in use, and so care must be taken ...
A vector field V defined on an open set S is called a gradient field or a conservative field if there exists a real-valued function (a scalar field) f on S such that = = (,,, …,). The associated flow is called the gradient flow , and is used in the method of gradient descent .
It is a well-known result [3] that such vector fields are isomorphic to , the tangent space at identity. In fact, if we let act on itself via right-multiplication, the corresponding fundamental vector fields are precisely the left-invariant vector fields.
This idea generalizes to arbitrary smooth maps. Suppose that X is a vector field on M, i.e., a section of TM. Then, yields, in the above sense, the pushforward φ ∗ X, which is a vector field along φ, i.e., a section of φ ∗ TN over M. Any vector field Y on N defines a pullback section φ ∗ Y of φ ∗ TN with (φ ∗ Y) x = Y φ(x). A ...
A lamellar vector field is a special case given by vector fields with zero curl. The adjective "lamellar" derives from the noun "lamella", which means a thin layer. The lamellae to which "lamellar vector field" refers are the surfaces of constant potential, or in the complex case, the surfaces orthogonal to the vector field. [1]
