title: Compression-based template matching

authors: Inglis, Stuart J.

subjects: Machine learning

abstract: Textual image compression is a method of both lossy and lossless image compression that is particularly effective for images containing repeated sub-images, notably pages of text (Mohiuddin et al., 1984; Witten et al., 1992). The process comprises three main steps:
• Extracting all the characters from an image;
• Building a library that contains one representative for each character class;
• Compressing the image with respect to the library.

title: Feasibility study of green hydrogen to decarbonise New Zealand’s industries

authors: Walmsley, Michael R.W.

subjects: green hydrogen

abstract: Adopting renewable feedstocks is a transformative approach to diminish the reliance on fossil feedstocks such as natural gas and coal in the chemical industry. This research evaluates the potential for Aotearoa-New Zealand, particularly in the North Island, to harness green hydrogen production as a substitute for fossil fuels across industries. The study's scope encompasses examining renewable energy technologies, their capacity factors based on location, types of electrolysers, the conversion process, and the sizing of hydrogen storage reservoirs. An analysis of the levelized cost of hydrogen (LCOH) throughout the value chain in various scenarios has been conducted for the years 2020 to 2040 while considering the country’s resource constraints. The issue is addressed through an optimization-based framework characterized by a multi-period, mixed-integer linear programming (MILP) model. The outcomes demonstrate the capability of integrating all these components within the mathematical framework to yield optimal solutions for transitioning towards a sustainable hydrogen economy.

title: Speaking the unspoken: Racism, sport and Māori

authors: Hippolite, Holly Raima

subjects: New Zealand

abstract: In this paper, we consider the silence that surrounds issues of racism in New Zealand sport. We argue that the intersection of two key ideologies – New Zealand’s purported history of good race relations, and the positive contribution that sport is believed to make to racial equality – contribute to a culture of silence in which it is difficult to talk about, let alone discuss constructively, Māori experiences of racism. Our aim is to put the issue on the agenda through engagement with ten experienced Māori sport participants, coaches and administrators whose experiences demonstrate the existence of, and pain caused by, cultural and institutional racism in New Zealand sport. In this aim, we do not seek to hide behind a veil of neutrality or objectivity. Rather, following a kaupapa Māori research approach, our interest is in bringing to light the voices, frustrations and concerns of Māori sportspeople in order to contribute to a much-needed conversation.
