Implications for the Conservation of Deep-Water Corals in the Face of Multiple Stressors: A Case Study from the New Zealand Region
The waters around New Zealand are a global hotspot of biodiversity for deep-water corals; approximately one sixth of the known deep-water coral species of the world have been recorded in the region. Deep-water corals are ... -
Current issues and potential solutions for the electrospinning of major polysaccharides and proteins: A review
(Elsevier BV, 2023-09)Biopolymers, especially polysaccharides and proteins, are the promising green replacement for petroleum based polymers. Due to their innate properties, they are effectively used in biomedical applications, especially tissue ... -
Post-disaster functional recovery of the built environment: A systematic review and directions for future research
(Elsevier, 2023-09-01)Life safety has been a primary design requirement in codes and standards for the built environment. However, over the past several years, better building performance goals that consider acceptable recovery times and continued ... -
teex: A toolbox for the evaluation of explanations
(Elsevier BV, 2023-10-28)We present teex, a Python toolbox for the evaluation of explanations. teex focuses on the evaluation of local explanations of the predictions of machine learning models by comparing them to ground-truth explanations. It ... -
A survey on compositional algorithms for verification and synthesis in supervisory control
(Springer Science and Business Media LLC, 2023-08-21)This survey gives an overview of the current research on compositional algorithms for verification and synthesis of modular systems modelled as interacting finite-state machines. Compositional algorithms operate by repeatedly ... -
Attribution of 2022 early-spring heatwave in India and Pakistan to climate change: lessons in assessing vulnerability and preparedness in reducing impacts
(IOP Publishing, 2023)In March 2022, large parts over the north Indian plains including the breadbasket region, and southern Pakistan began experiencing prolonged heat, which continued into May. The event was exacerbated due to prevailing dry ... -
Minimum drain setback distances to protect New Zealand wetlands: tool development
(2023-07-01)This report documents the development of a Wetland Drain Setback Tool (WDST) for New Zealand freshwater wetlands. The purpose of this tool is to assess the potential effects of historical and new drains on wetland ecosystems ... -
Machine Learning for PAC1D and SESE
(U.S. Air Force Research Laboratory, 2023-04-03)This document outlines various machine learning approaches that were taken in an effort to surrogate numerical models Python Ablation Code 1-Dimension (PAC1D) and Scalable Effects Simulation Environment (SESE), with the ... -
Using faecal DNA metabarcoding to determine the diet of the long-tailed bat, Chalinolobus tuberculatus
(Informa UK Limited, 2023-01-01)Dietary analysis of nocturnal aerial insectivores such as bats is not possible by direct visual observation of predation, therefore diet is traditionally determined by analysing dietary remains in scats. Analysing DNA in ... -
Geotechnical properties of liquefied pumiceous layers in lakes
(Australian Geomechanics Society, 2022-04-29)Earthquake failures in volcanic-ash soils are relatively common, considering their physical nature and the fact that such deposits tend to occur in areas with high seismicity in which the volcanism, responsible for their ... -
Effect of Mn on the Properties of Powder Metallurgy Ti-2.5Al-xMn Alloys.
(MDPI, 2023-07-10)Titanium alloys are the ideal material for a wide range of structural applications, but their high cost compared to other metals hinders their adoption. Powder metallurgy and cheap alloying elements can be used to create ... -
Evaluating the properties, fate and individual-to-ecosystem level impacts of contrasting microplastics in freshwaters
(The Swedish Environmental Protection Agency, 2023-06)Microplastic particles (MPs) are fragments, fibres and other shapes derived from plastic polymers in the size range of 1–5 000 μm. Concern about the environmental impacts of MPs and their implications for human wellbeing ... -
Interactive system modelling for the Internet of Things
(ACM, 2023)The rapid growth in the number of Internet of Things (IoT) systems and their increasing use in safety-critical domains has led to the need for an evolution of development methods. Model-Driven Development (MDD) approaches ... -
Mobility and emplacement of an ancient, large-volume pyroclastic flow, Ongatiti Ignimbrite, North Island, New Zealand
(Elsevier, 2023-07-28)Pyroclastic flows are the most devastating phenomena of explosive volcanic eruptions. These hazardous fast-moving, hot, concentrated density currents are able to travel several tens of kilometers radially away from their ... -
Promoting social and environmental justice to support Indigenous partnerships in urban ecosystem restoration
(WILEY, 2020-11-27)Urban ecological restoration typically employs western science approaches to restore degraded ecosystems. As yet, few restoration groups acknowledge the history of these degraded urban sites, despite connections, past and ... -
Making positive use of the fibrillation of lyocell fibres in composite materials
(Elsevier B.V., 2023-07-01)The present study investigates the influence of surface fibrillation of lyocell fibres on the adhesion and resulting properties of short fibre-reinforced polypropylene (PP) and polylactide (PLA) composites. Fibrillation ... -
The role of climate change in extreme rainfall associated with Cyclone Gabrielle over Aotearoa New Zealand’s East Coast
(Grantham Institute., 2023-03-14)Aotearoa is a country with good channels for communicating forecasts of extreme rainfall. Significant warning was able to be given for Cyclone Gabrielle of expected heavy rainfall and the potential for rapidly rising rivers, ... -
Experimental characterization of the fracture properties of pultruded GFRP structural elements
(Elsevier BV, 2023)Pultruded Fiber Reinforced Polymers (FRPs) are a class of novel composite materials with remarkable strength (comparable or even greater to that of steel) and resistance to environmental effects. However, the strongly ... -
Biodiversity enhances the multitrophic control of arthropod herbivory
(AMER ASSOC ADVANCEMENT SCIENCE, 2020-11-01)Arthropod herbivores cause substantial economic costs that drive an increasing need to develop environmentally sustainable approaches to herbivore control. Increasing plant diversity is expected to limit herbivory by ... -
Consistent predator-prey biomass scaling in complex food webs
(Springer Nature, 2022-08-25)The ratio of predator-to-prey biomass is a key element of trophic structure that is typically investigated from a food chain perspective, ignoring channels of energy transfer (e.g. omnivory) that may govern community ...
