Colour classification of 1486 lakes across a wide range of optical water types
(MDPI AG, 2018)Remote sensing by satellite-borne sensors presents a significant opportunity to enhance the spatio-temporal coverage of environmental monitoring programmes for lakes, but the estimation of classic water quality attributes ... -
Synthesis and characterisation of organo-platinum(II) complexes of the N,O-donor ligands hippuric acid (N-benzoylglycine) and N-phenylanthranilic acid
(Elsevier, 2016)Reaction of [PtCl₂(cod)] (cod = cyclo-octa-1,5-diene) with either hippuric acid [PhC(O)NHCH₂COOH] or N-phenylanthranilic acid (ortho-PhNHC₆H₄COOH) in refluxing dichloromethane in the presence of silver(I) oxide gave the ... -
Microbial biogeography of 925 geothermal springs in New Zealand
(Nature Publishing Group, 2018)Geothermal springs are model ecosystems to investigate microbial biogeography as they represent discrete, relatively homogenous habitats, are distributed across multiple geographical scales, span broad geochemical gradients, ... -
Difference in details: transfer learning case study of "cryptic" plants and moths
(2018)Can we classify species of very similar looking organisms quickly and accurately using only out of the box feature transfer? What if we only have small number of images? This experimental paper is part of on-going project ... -
Effect of contextual information on object tracking
(IEEE, 2017)Local object information, such as the appearance and motion features of the object, are useful for object tracking in videos provided the object is not occluded by other elements in the scene. During occlusion, however, ... -
Corrections to Compact Nonlinear Model of an Implantable Electrode Array for Spinal Cord Stimulation
(Institute of Electrical and Electronics Engineers, 2018)Reference [1] describes the construction of a model of the electrode-electrolyte interface and the surrounding electrolyte for a platinum-electrode array used in Spinal Cord Stimulation (SCS) applications. In that paper, ... -
Biophysical modeling of neural plasticity induced by transcranial magnetic stimulation
(Elsevier, 2018)Transcranial magnetic stimulation (TMS) is a widely used noninvasive brain stimulation method capable of inducing plastic reorganisation of cortical circuits in humans. Changes in neural activity following TMS are often ... -
Quaternary research in New Zealand and relationship to the International Union for Quaternary Research (INQUA). Annual Report for the Catalyst Fund: Influence 2017 (with Appendix).
(School of Science, University of Waikato, Hamilton., 2018)It is anticipated that this report has been discussed in some form with the national committee or organisation identified above and provides the wider view of this network. I have discussed the report with some of the ... -
Location of Te Wahitapu Stream and other possible streams in 1877
(2009)Review of evidence to establish, with as much confidence as possible, the path of the Te Wahitapu Stream at Matapouri in 1877. The review also examines if other streams may have been present on or in the vicinity of Te ... -
Classifying Transverse Motion in Time-of-Flight Range Imaging
(OSA Publishing, 2018)Classification of step motion in time-of-flight imaging using the stochastic oscillator and autocorrelation is proposed. Machine learning algorithms correctly identify the step location in 65–75% of trials, with apparent ... -
Wave-frequency flows within a near-bed vegetation canopy
(Elsevier Ltd., 2017)We study water flows and wave dissipation within near-bed pneumatophore canopies at the wave-exposed fringe of a mangrove forest on Cù Lao Dung Island, in the Mekong Delta. To evaluate canopy drag, the three-dimensional ... -
A strategy for the correction of effects of jitter in AMCW lidar images
(IEEE, 2013)Full-field range imaging cameras, which are an example of amplitude modulated continuous wave (AMCW) lidar, are subject to multiple error sources. In this paper we consider the possibility that a global jitter and/or drift ... -
Niche partitioning of intertidal seagrasses: evidence of the influence of substrate temperature
(WILEY, 2018)• The influence of soil temperature on rhizome depths of four intertidal seagrass species was investigated in central Queensland, Australia. We postulated that certain intertidal seagrass species are soil temperature‐sensitive ... -
Additive manufacturing of Ti-6Al-4V with added boron: Microstructure and hardness modification
(Trans Tech Publications, 2018)Titanium alloy composites with titanium boride (TiB) discontinuous reinforcement have shown improved performance in terms of strength, stiffness, and hardness. Producing this composite through selective laser melting (SLM) ... -
The effect of heat treatments on microstructure and mechanical properties of as-extruded Ti-6Al-4V alloy rod from blended elemental powders
(Trans Tech Publications, 2018)In this study, Ti-6Al-4V bars were first prepared by extrusion of powder compacts from blended powder mixtures in the beta phase region, then the as-extruded bars were heat-treated following four different conditions: beta ... -
On microstructural evolution and mechanical properties of Ti-5Al-5V-5Mo-3Cr alloy synthesised from elemental powder mixtures
(Elsevier, 2018)In this paper, we explored to prepare a multi-compositional titanium alloy, Ti-5Al-5V-5Mo-3Cr (Ti-5553), by powder compact extrusion from elemental powder mixtures, and investigate the microstructure variation during the ... -
Effect of minor titanium addition on copper/diamond composites prepared by hot forging
(Springer Verlag, 2018)Copper/diamond composites have great potential to lead the next generation of advanced heat sink materials for use in high-power electronic devices and high-density integrated circuits because of their potential excellent ... -
Producing High-Quality Titanium Alloy by a Cost-Effective Route Combining Fast Heating and Hot Processing
(Springer, 2018)Powder metallurgy is a very attractive method for producing titanium alloys, which can be near-net-shape formed and have freedom in composition selection. However, applications are still limited due to product affordability. ... -
Evaluation of reactive induction sintering as a manufacturing route for blended elemental Ti-5Al-2.5Fe alloy
(Elsevier, 2018)This work focuses on gaining a better understanding of the feasibility of using reactive induction sintering to obtain the alloy Ti-5Al-2.5Fe using Ti, Al and Fe powders (i.e. via a blended elemental approach). For this, ... -
Effect of microwave sintering parameters on the physical and mechanical properties of pure Ti and blended elemental Ti alloys
