title: Playing videos in an augmented reality setting on an Android mobile platform

authors: Li, Shuzu

abstract: Augmented Reality (AR) is typically used to superimpose pictures, texts or 3D models on a camera view of the surrounding reality. In this thesis, we use the video in an AR environment as a rich way to present information. This thesis explored the feasibility of playing elements of videos via Augmented Reality on an Android mobile phone platform. Our prototype, VideoAR, is introduced in this thesis. VideoAR presents the capability to manipulate videos in AR such as playing, shaping and background sub- tracting. It has been developed based on the Persona and Scenario method, and evaluated via observation and measurement methods. Overall, we were successful in overlaying elements of videos with camera views in an AR-like fashion. However, we identified a number of factors that can affect the quality of video playing in AR such as distance, angle, light, cover, texture, colour and shape. The observed results encour- age the use of video in AR type environments on end-user mobile phones for industries like tourism, film, academia and architecture.

title: Transport and retention of benthic marine invertebrates in the Southern Tauranga Basin

authors: Monahan, Bradley John

subjects: Dispersal

abstract: Dispersal is the process in which individuals are transferred between populations, and is essential for population sustainability and longevity. In estuarine soft sediment communities, dispersal often occurs as the interaction between the individual and tidal flows. Many coastal benthic marine invertebrate populations have been considered open because of the dispersal potential of a pelagic larval phase, with populations maintained by an external supply of recruits. However, for estuarine populations, recent evidence has suggested that populations may be more closed because of local hydrodynamic conditions causing larval retention within the source estuary. In this thesis, field observations and numerical simulations were used to investigate the effect of estuary morphology on the transport and retention of benthic invertebrate larvae in Tauranga Harbour, a large (218 km2), shallow (mean depth = 2.8 m) meso-tidal estuary. Previous studies indicate that residence times extracted from hydrodynamic modelling vary throughout the harbour, due to residual circulation patterns caused by complex channel morphology. Field observations indicate increased abundance and differing community composition of invertebrate larvae in the upper harbour compared to the lower. Tidal circulation is asymmetrical, with transport through a seaward channel during flood tides, and in a landward channel during ebb, suggesting that larval retention in the upper harbour may provide a source of larvae for the lower harbour. Larval transport pathways were evaluated by a coupled hydrodynamic-transport model and confirmed those observed in the field. Modelled larvae, released under different stages of spring-neap tidal cycle in the upper harbour, were retained for up to 16 d whereas retention for larvae released in other harbour locations was much more variable and depended on the timing of release and direction of initial transport. Results of this study highlight the impact of complex channel morphology (particularly at a scale of 10s to 100s of meters) on the large scale circulation and subsequent transport and retention of benthic invertebrate larvae. Understanding these influences on the transportation of benthic invertebrate larvae and the identification of retentive regions, will aid future population management or conservation efforts

title: Legal responses to mental health: Is therapeutic jurisprudence the answer – the experience in New Zealand

authors: Toki, Valmaine

abstract: The orthodox understanding of ‘ethics’ encompasses a system of moral principles that define good and bad behavior. When applied to mental health, various jurisdictions, including New Zealand, have codified these principles together with the obligations on health service providers to meet these codified principles and standards. Underpinning this relationship is one of mutual trust where the physician has a responsibility, for example, to secure informed consent prior to any treatment. The existence of this therapeutic relationship can be applied when an offender who presents with a mental illness is subject to the criminal justice system.
