Heisenberg groups and their automorphisms over algebras with central involution
Robert W. Johnson
Heisenberg groups over algebras with central involution and their automorphism groups are constructed. The complex quaternion group algebra over a prime field is used as an example…
AMGKQ: An Efficient Implementation of Adaptive Multivariate Gauss-Kronrod Quadrature for Simultaneous Integrands in Octave/MATLAB
Robert W. Johnson
The algorithm AMGKQ for adaptive multivariate Gauss-Kronrod quadrature over hyper-rectangular regions of arbitrary dimensionality is proposed and implemented in Octave/MATLAB. It c…
Remarks on the derivation and evaluation of the Stacey-Sigmar model for tokamak equilibrium
Robert W. Johnson
The Stacey-Sigmar model for tokamak equilibrium as presented in the literature relies heavily on the neoclassical theory of the electrostatic field. Its neglect of Gauss's law is i…
Applications of the Beta Distribution Part 1: Transformation Group Approach
Robert W. Johnson
A transformation group approach to the prior for the parameters of the beta distribution is suggested which accounts for finite sets of data by imposing a limit to the range of par…
Some Notes on the Use of the Windowed Fourier Transform for Spectral Analysis of Discretely Sampled Data
Robert W. Johnson
The properties of the Gabor and Morlet transforms are examined with respect to the Fourier analysis of discretely sampled data. Forward and inverse transform pairs based on a fixed…
Prediction of particle type from measurements of particle location: A physicist's approach to Bayesian classification
Robert W. Johnson
The Bayesian approach to the prediction of particle type given measurements of particle location is explored, using a parametric model whose prior is based on the transformation gr…
