Conical Singular Points and Vector Fields
Vestnik St. Petersburg University, Mathematics, 2020 In this article, several examples of mechanical systems which configuration spaces are smooth manifolds with a unique singular point are considered. Configuration spaces are the following: two smooth curves with a common point (or tangent) on the two-dimensional torus, four smooth curves on the four-dimensional torus with a common point, twodimensional

Singular spectrum analysis for effective feature extraction in hyperspectral imaging [PDF]
, 2014 As a very recent technique for time series analysis, Singular Spectrum Analysis (SSA) has been applied in many diverse areas, where an original 1D signal can be decomposed into a sum of components including varying trends, oscillations and noise ...

FUSION AND THE NEVEU-SCHWARZ SINGULAR VECTORS [PDF]
International Journal of Modern Physics A, 1994 Bauer, di Francesco, Itzykson and Zuber recently proposed an algorithm to construct all singular vectors of the Virasoro algebra. It is based on the decoupling of (already known) singular fields in the fusion process. We show the extension of their algorithm to the Neveu-Schwarz superalgebra.

SINGULAR VECTORS OF THE TOPOLOGICAL CONFORMAL ALGEBRA [PDF]
International Journal of Modern Physics A, 1996 A general construction is found for “topological” singular vectors of the twisted N=2 superconformal algebra. It demonstrates many parallels with the known construction for affine sℓ(2) singular vectors due to Malikov–Feigin–Fuchs, but is formulated independently of the latter.

DIGITAL WATERMARKING IN THE SINGULAR VECTOR DOMAIN [PDF]
International Journal of Image and Graphics, 2008 Many current watermarking algorithms insert data in the spatial or transform domains like the discrete cosine, the discrete Fourier, and the discrete wavelet transforms. In this paper, we present a data-hiding algorithm that exploits the singular value decomposition (SVD) representation of the data.

Singular vectors for the WN algebras [PDF]
Journal of Mathematical Physics, 2018 In this paper, we use free field realisations of the A-type principal, or Casimir, WN algebras to derive explicit formulae for singular vectors in Fock modules. These singular vectors are constructed by applying screening operators to Fock module highest weight vectors. The action of the screening operators is then explicitly evaluated in terms of Jack
