 This special Section of the ANZIAM Journal (Electronic Supplement) contains the refereed papers from the 2020 Mathematics and Statistics in Industry Study Group (MISG 2020) held at the University of Newcastle from 28 January -- 1 February 2020. The MISG is a special interest meeting of ANZIAM, the Australia and New Zealand Industrial and Applied Mathematics (ANZIAM) division of the Australian Mathematics Society. The MISG meetings take place annually and provide a forum where projects proposed by industry can be worked on intensively, by high profile scientists in the fields of Applied Mathematics, Statistics and Operations Research, from Australia, New Zealand and the world beyond, along with representatives from the industries proposing the projects.
 The writing of these papers was coordinated by the project moderators in consultation with the coauthors and company representatives. The manuscripts were submitted to the editors, Associate Professor Mike Meylan, Professor Ngamta Thamwattana and Professor Tony Roberts, and were subsequently refereed by two expert referees. On the advice of the referees, manuscripts were accepted for publication, subject to the recommended revisions, and formally approved by the editorial committee.
 At MISG 2020, six projects were presented from diverse industries, with 78 delegates participating.

Preface to the proceedings

This Special Part of the ANZIAM Journal (supplement) contains the refereed papers from the tenth Biennial Computation Techniques and Applications Conference (CTAC2001) held at the University of Queensland, Brisbane, during 16-18 July 2001. The CTAC series of conferences is held under the auspices of the Computational Mathematics Group of the Australian and New Zealand Industrial and Applied Mathematics (ANZIAM) division of the Australian Mathematics Society. They provide a forum for scientists, engineers, and mathematicians interested in the development of computational techniques and their application to problems of practical importance. Previous conferences in the CTAC series have been held at University of Sydney (1983), University of Melbourne (1985), University of Sydney (1987), Griffith University, Brisbane (1989), University of Adelaide (1991), Australian National University, Canberra (1993), Swinburne University of Technology, Melbourne (1995), University of Adelaide (1997), Australian National University, Canberra (1999). There were about 100 participants at the conference, five of whom gave keynote addresses as part of the general program for CTAC2001-these speakers and the titles of their presentations were: Real Time Optimisation and Nonlinear Model Predictive Control for Large DAE Models Prof Hans-Georg Bock, Interdisciplinary Center for Scientific Computing (IWR), Heidelberg, Germany; Some Computational Problems Arising in Continuous Time Finance Prof Carl Chiarella, School of Finance and Economics, University of Technology, Sydney, Australia; Matrix Decomposition Algorithms in Finite Element Methods for Poisson's Equation Prof Graeme Fairweather, Mathematical and Computer Sciences, Colorado School of Mines, Golden, USA. Computational Problems in Landscape Design for Conservation Prof Hugh Possingham, Departments of Zoology and Mathematics, University of Queensland, Brisbane, Australia; Iterative Methods for Nonsymmetric Ill-posed Problems Prof Lothar Reichel, Kent State University, Ohio, USA; In addition to these invited presentations, 74 contributed papers were presented at the conference. Of these, 48 were submitted for consideration for the CTAC2001 Proceedings, and 43 were accepted for publication after each was peer-reviewed by at least two referees and the papers revised to the satisfaction of the referees. Following the convention established in previous CTAC proceedings, the papers appearing here have not been grouped by topic; the abstracts of the five invited speakers are included, followed by the contributed papers in alphabetical order of the first author. As with previous CTAC Proceedings, the papers cover a wide variety of topics with the usual CTAC emphasis on both industrial applications and numerical techniques. A new feature is the marked number of presentations in the areas of financial mathematics and computational biology. The editors thank the referees for their time and assistance with the refereeing process, and the ANZIAM Journal of the (supplement) for agreeing to publish the proceedings as a journal special issue. Also, the editors would like to especially acknowledge the hard work of the Organising Committee and in addition, Jerard Barry, Markus Hegland and Yvette Zuidema.
