• #### Approximation and Visualization of Sets Defined by Iterated Function Systems ﻿

(University of Regina, 1991-03)
An iterated function system (IFS) is defined to be a set of contractive affine transformations. When iterated, these transformations define a closed set, called the attractor of an IFS, which has fractal characteristics. ...
• #### Rendering Methods for Iterated Function Systems ﻿

(North-Holland, 1991-12)
This paper describes rendering methods for iterated function systems (IFS’s). The rendering process consists of the generation of a field of data using an IFS and its visualization by means of computer graphics. Two groups ...
• #### The Escape Buffer: Efficient Computation of Escape Time for Linear Fractals ﻿

(Canadian Human Computer Communications Society, 1995-05-17)
The study of linear fractals has gained a great deal from the study of quadratic fractals, despite important differences. Methods for classifying points in the complement of a fractal shape were originally developed for ...
• #### Post-magmatic alteration in eudialyte from the North Qoroq centre, South Greenland ﻿

(Mineralogical Society of Great Britian, 1997-02)
The North Qoroq centre comprises a series of nested nepheline syenite intrusions and forms part of the midlate Proterozoic Gardar province of South Greenland. Within the centre fractionation has produced varied rock types ...

• #### A note on the fixed-point iteration for the matrix equations $X\pm A^*X^{-1}A=I$ ﻿

(Elsevier, 2008)
The fixed-point iteration is a simple method for finding the maximal Hermitian positive definite solutions of the matrix equations $X\pm A^*X^{-1}A=I$ (the plus/minus equations). The convergence of this method ...
• #### Detecting and solving hyperbolic quadratic eigenvalue problems ﻿

(SIAM, 2009)
Hyperbolic quadratic matrix polynomials $Q(\lambda) = \lambda^2 A + \lambda B + C$ are an important class of Hermitian matrix polynomials with real eigenvalues, among which the overdamped quadratics are those with ...
• #### Convergence Analysis of the Doubling Algorithm for Several Nonlinear Matrix Equations in the Critical Case ﻿

(SIAM, 2009)
In this paper, we review two types of doubling algorithm and some techniques for analyzing them. We then use the techniques to study the doubling algorithm for three different nonlinear matrix equations in the critical ...
• #### An Improved Arc Algorithm for Detecting Definite Hermitian Pairs ﻿

(SIAM, 2009)
• #### Simultaneous Tracking and Activity Recognition with Relational Dynamic Bayesian Networks ﻿

(Department of Computer Science, University of Regina, 2011-03-30)
Taking into account relationships between interacting objects can improve the understanding of the dynamic model governing their behaviors. Moreover, maintaining a belief about the ongoing activity while tracking allows ...
