Harmonic Analysis of Radon Filtrations for Sn and GLn(q)
(2014)
We present a unified approach to the study of Radon transforms
related to symmetric groups and to general linear groups GLn(q),
regarded as q−analogues of the former. In both cases, we define a
sequence of generalized ...
On spherical invariance
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 2011)
In 1964 Pommerenke introduced the notion of linear invariant family for locally injective analytic functions defined in the unit disk of the complex plane. Following Ma and Minda (who extended this notion to spherical ...
Subdifferential characterization of probability functions under Gaussian distribution
(Springer Verlag, 2019)
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature and Mathematical Optimization Society. Probability functions figure prominently in optimization problems of engineering. They may be nonsmooth even if all input ...
Reconstructing anatomy from electro physiological data
(Elsevier, 2017)
Here we show how it is possible to make estimates of brain structure based on MEG data. We do this by reconstructing functional estimates onto distorted cortical manifolds parameterised in terms of their spherical harmonics. ...
Solutions of some boundary value problems for a new class of elastic bodies. Comparison with predictions of the classical theory of linearized elasticity: Part II. A problem with spherical symmetry
(Springer, 2015)
In Part II of the paper, we study the response of a spherical annular region of the same strain limiting elastic body considered in Part I, wherein the linearized strain is a nonlinear function of the stress. We study the ...
Aerodynamic coefficients of irregular non-spherical particles at intermediate Reynolds numbers
(Elsevier, 2022-03)
In industrial processes such as those related with paper industry, coal or biomass combustion, particles can take
irregular non-spherical shapes. However, in related numerical computations the assumption of spherical ...
Ga1- xInxAsySb1- y/GaSb spherical quantum dot in a magnetic field
(2012-12)
Quaternary semiconductor alloys type-I are appropriated materials for heterostructure devices because they provide a natural form to tune the magnitude of the band gap so that it can operate in the mid-infrared (mid-IR) ...
General exact solution for homogeneous time-dependent self-gravitating perfect fluids
(1990)
A procedure to obtain the general exact solution of Einstein equations for a self-gravitating spherically symmetric static perfect fluid obeying an arbitrary equation of state is applied to time-dependent Kantowski-Sachs ...
General exact solution for homogeneous time-dependent self-gravitating perfect fluids
(1980)
A procedure to obtain the general exact solution of Einstein equations for a self-gravitating spherically symmetric static perfect fluid obeying an arbitrary equation of state is applied to time-dependent Kantowski-Sachs ...
Evaluation of localization precision by proposed quasi-spherical nested microphone array in combination with multiresolution adaptive steered response power
(Slovak Univ. Technology, 2020)
Multiple sound source localization in noisy and reverberant conditions is one of the important challenges in the speech signal processing. The aim of this article is three-dimensional sound source localization in undesirable ...
