Spherical domain
Laplace's equation imposes that the Laplacian of a scalar field f is zero. (Here the scalar field is understood to be complex, i.e. to correspond to a (smooth) function .) In spherical coordinates this is: Consider the problem of finding solutions of the form f(r, θ, φ) = R(r) Y(θ, φ). By separation of variables, two differential equations result by imposing Laplace'… WebAdversarial domain adaptation has been an effective approach for learning domain-invariant features by adversarial training. In this paper, we propose a novel adversarial domain adaptation approach defined in the spherical feature space, in which we define spherical classifier for label prediction and spherical domain discriminator for discriminating …

WebThe spherical coordinate system is a three-dimensional system that is used to describe a sphere or a spheroid. By using a spherical coordinate system, it becomes much easier to work with points on a spherical surface. For example, the cartesian equation of a sphere is given by x 2 + y 2 + z 2 = c 2.

Spherical coordinates are useful in analyzing systems that have some degree of symmetry about a point, such as volume integrals inside a sphere, the potential energy field surrounding a concentrated mass or charge, or global weather simulation in a planet's atmosphere. See more In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle … See more To define a spherical coordinate system, one must choose two orthogonal directions, the zenith and the azimuth reference, and an origin point in space. These choices determine a reference plane that contains the origin and is perpendicular to the … See more As the spherical coordinate system is only one of many three-dimensional coordinate systems, there exist equations for converting … See more The following equations (Iyanaga 1977) assume that the colatitude θ is the inclination from the z (polar) axis (ambiguous since x, y, and z are mutually normal), as in the … See more Just as the two-dimensional Cartesian coordinate system is useful on the plane, a two-dimensional spherical coordinate system is useful on the surface of a sphere. In this system, the sphere is taken as a unit sphere, so the radius is unity and can generally be … See more It is also possible to deal with ellipsoids in Cartesian coordinates by using a modified version of the spherical coordinates.
