Research
 Richard's Stuff
 My blog, mostly about my work on audio reproduction and acoustics.

 Preprint of a paper presented at the 143rd Convention of the Audio Engineering Society, New York, Oct. 2017.
 R. Taylor, K. Manke and D.B. (Don) Keele, Jr. Constant Directivity CircularArc Line Arrays of Dipole Elements
 Preprint of a paper presented at the 143rd Convention of the Audio Engineering Society, New York, Oct. 2017.

 Preprint of a paper presented at the 143rd Convention of the Audio Engineering Society, New York, Oct. 2017.
 Delaying Room Reflections: Constraints on Room Size and
Loudspeaker Placement
 A draft of some work on the geometry of sound reflections in rooms.
 S.R. Taylor and S.A. Campbell. Approximating Chaotic Saddles for Delay Differential Equations. 2007.
 Preprint of some recent work on numerical analysis of transient chaos in DDEs, published in Phys. Rev. E.
 Probabilistic Properties of Delay Differential Equations. 2004.
 Full text of my PhD thesis.
 Chaotic transport through the solar system
 Slides from a talk I gave a few times in 2006. Also my first experiment with Prosper.
 Consonance and Dissonance
 Slides from a talk I gave on mathematics and music in 2010.
 Calculus of Variations
 Slides from a talk I gave in 2007.
 Tablix
 Implementation of a genetic algorithm for scheduling optimization. I've contributed some code to this project and used it to optimize the course schedule at Okanagan College and the job rotations in the laboratory at Royal Inland Hospital.
 R Project for Statistical Computing
 "R" is a highlevel scripting language for numerical and graphical work, somewhat like Octave or Matlab. It's free and open source. All the images shown here were made with the help of R.
Software
 rtplugins
 A collection of LADSPA plugins for active loudspeaker crossover and eq.
Images
 Miscellaneous Images

 My research often leads to interesting images. Some of these are my takes on wellknown examples; some are my originals. Click the thumbnails for details and (mostly inadequate) explanations.
 Basins of attraction for a magnetic pendulum
 Some nice images of basins of attraction for a 3D pendulum suspended over magnets.
 Strange attractor for a periodically forced pendulum
 A classic. More fractal images and psychedelic animations.
 Newton's Method
 Fractals show up when Newton's method is used to find complex roots of a polynomial. Another classic.
 Basins of attraction for delay differential equations
 I've found transient chaos and fractal basins in some delay differential equations. Pretty pictures.
