SMSIR: Spherical Measure Based Spherical Image Representation
IEEE Transactions on Image Processing, 2021This paper presents a spherical measure based spherical image representation(SMSIR) and sphere-based resampling methods for generating our representation. On this basis, a spherical wavelet transform is also proposed. We first propose a formal recursive definition of the spherical triangle elements of SMSIR and a dyadic index scheme.

Spherical Orthotomic and Spherical Antiothotomic
Acta Mathematica Sinica, English Series, 2007Wird ein fester Punkt \(P\) an allen Tangenten \(t\) einer Raumkurve \(c\) des dreidimensionalen Euklidischen Raumes gespiegelt, so erhält man die so genannte orthotome Kurve \(c^*\) von \(P\) bezüglich \(c\). Umgekehrt heißt die Kurve \(c\) die antiorthotome Kurve von \(c^*\) bezüglich \(P\).

A historical perspective of the development of spherical nucleic acid (SNA) conjugates and other three-dimensional nucleic acid nanostructures is provided. This Perspective details the synthetic methods for preparing them, followed by a discussion of their unique properties and theoretical and experimental models for understanding them.

Sphericities of non-spherical objects
Particuology, 2012Abstract Sphericity, as one of the most important shape parameter for non-spherical objects, is extensively applied in evaluating the porosity or packing density of particles. In this paper, the sphericities of common non-spherical objects are deduced and investigated. Maximum sphericities and optimum shapes of these objects are presented as well.

SummarySpheres, or more usually spherical surfaces, are important in electron backscatter diffraction. Both electron backscatter patterns (EBSPs) and pole figure texture data are more accurately represented on the spherical surface, S2; and unit quaternions, which are the optimal method for orientation calculations, exist on the surface of the ...

Tensor spherical harmonics and tensor spherical splines
manuscripta geodaetica, 1994In this paper, we deal with the problem of spherical interpolation of discretely given data of tensorial type. To this end, spherical tensor fields are investigated and a decomposition formula is described. Tensor spherical harmonics are introduced as eigenfunctions of a tensorial analogon to the Beltrami operator and discussed in detail.

This paper reports the creation of a tandem liquid crystal cell arrangement capable of simulating the performance of a spherical lens. Electrical modulation of the index of refraction creates focusing behavior. The modulation is induced by a set of electrodes whose individual voltages are arranged to provide a cylindrical exit wave front for a uniform ...

Sender's “Spherical” Philosophy
PMLA/Publications of the Modern Language Association of America, 1954Ramón sender, perhaps the most gifted of living Spanish novelists, has been, since 1946, an American citizen. Since 1947 he has been Professor of Spanish at the University of New Mexico. Nine of his fourteen published novels have been translated into English, and have appeared in both American and British editions.
