Hidden features: Experiments with feature transfer for fine-grained multi-class and one-class image categorization
(IEEE, 2018)Can we apply out-of-the box feature transfer using pre-trained convolutional neural networks in fine-grained multiclass image categorization tasks? What is the effect of (a) domainspecific fine-tuning and (b) a special-purpose ... -
Lake Rotokakahi water quality modelling
(Environmental Research Institute, Faculty of Science and Engineering, The University of Waikato, 2014)Lake Rotokakahi is an iwi-owned lake, administered by the Lake Rotokakahi Board of Control. The lake has a surface area of 4.4 km2, a mean depth of 17.5 m, and a catchment of 19.7 km2 of which most is in exotic forest ... -
Is engineering for me? Do girls have enough information to decide?
(2018)Increasing the diversity in engineering starts with increasing the proportion of the specific cohort choosing to study engineering. The proportion of women doing engineering is low. Common barriers to increasing the ... -
Development of a mental health recovery module for the WHOQOL
(Springer Science and Business Media LLC, 2019)Purpose The WHOQOL tools are widely used, multi-faceted, patient-rated, quality of life (QoL) measures, developed by the World Health Organization. The WHOQOL questionnaires are used to assess generic quality of life ... -
Signal processing approaches for Jitter extraction in time-of-flight range imaging cameras
(IEEE, 2018)The precision and accuracy of time-of-flight full-field range cameras are important for many applications, however there are a number of noise sources that degrade both precision and accuracy. Many of the noise sources ... -
Tree encroachment may lead to functionally-significant changes in peatland testate amoeba communities
(Elsevier, 2016)Climate change is likely to cause increased tree recruitment on open peatlands but we currently have little idea what consequences this vegetation change may have below-ground. Here we use transects across forested to open ... -
Waveguide joint design and validation for use in acoustic vector-corrected network analysers
(2019)The Vector-corrected Network Analyser (VNA) has been an indispensable tool for many decades in the field of RF and microwave engineering where the availability of calibrated and traceable results is taken for granted. ... -
How topography-dependent are topographic effects? Complementary numerical modeling of centrifuge experiments
(Elsevier, 2019-01-01)Topographic effects, the modification of seismic shaking by irregular topographies compared to flat ground, have been extensively studied. Very few studies, however, have investigated the effects of the stratigraphy and ... -
Local and distant Pacific climate signals in cave hydrochemistry: Waipuna cave, New Zealand
(2018)In this study, the preliminary results of monitoring at Waipuna cave, New Zealand, are introduced to support the development of speleothem paleoclimate archives of long-term variability in the El Niño-Southern Oscillation ... -
Regulation of phosphorus bioavailability by iron nanoparticles in a monomictic lake
(Nature Publishing Group, 2018)Dissolved reactive phosphorous (DRP) in lake systems is conventionally considered to predominate over other dissolved P species, however, this view neglects an important set of interactions that occurs between P and reactive ... -
A modest addendum to the english sediment core meta-database
(2017)Compilations of previous studies provide researchers with a source of valuable secondary data for re-analysis, an access route to identify relevant literature and an opportunity to systematically evaluate the research which ... -
Large leaves in warm, moist environments confer an advantage in seedling light interception efficiency.
(2019)Leaf size varies conspicuously along environmental gradients. Small leaves help plants cope with drought and frost, because of the effect of leaf size on boundary layer conductance; it is less clear what advantage large ... -
Cadmium mobilisation by dissolved organic matter in contaminated soils amended with compost and peat
(2019)Some organic matter (OM) soil amendments derived from biowaste have been shown to reduce plant uptake of Cd, which presents them as an attractive option for mitigating potential health risks on some contaminated soils. ... -
Towards a quantitative proxy of cave dripwater hydrology
(2018)Speleothems capture a wide range of geochemical signals related to hydroclimate variability. However, the quantification of climatic parameters (e.g. rainfall, temperature) using traditional proxies is hampered by the ... -
Holocene carbon accumulation in the peatlands of northern Scotland
(International Mire Conservation Group and International Peatland Society, 2019)The response of peatland carbon accumulation to climate can be complex, with internal feedbacks and processes that can dampen or amplify responses to external forcing. Records of carbon accumulation from peat cores provide ... -
35,000 years of hydrological variability in northern New Zealand from speleothem magnetism
(2018)Speleothem magnetism is the study of the origin and geo-enviromagnetic significance of magnetic minerals in speleothems. Allogenic magnetic particles are transported to speleothem sites from soils and sediments by hydrological ... -
Twenty-three unsolved problems in hydrology (UPH)–a community perspective
(Taylor & Francis Group, 2019)This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation ... -
[Dicyclohexyl(sulfanylidene)-λ⁵-phosphanyl]methanol
(MDPI AG, 2019)The title compound, [dicyclohexyl(sulfanylidene)-λ⁵-phosphanyl]methanol, Cy₂P(=S)CH₂OH (1), was obtained from the reaction between [Cy₂P(CH₂OH)₂]Cl with one molar equivalent of NaOH and an excess of elemental sulfur ... -
Staying safe on a surf beach: What are rip currents?
(Frontiers Media SA, 2019)Everyone enjoys visiting the beach and playing or swimming in the water, but sometimes, waves breaking on beaches can create strong, narrow currents that can pull you out of your depth and into deeper water, where you may ... -
