title: Implementing an event-driven service-oriented architecture in TIP

authors: Rinck, Michael

subjects: computer science

abstract: Many mobile devices have a density of services, many of which are context or location-aware. To function, many of these services have to collaborate with other services, which may be located in many different places and networks. There is often more then on service suitable for the task at hand. To decide which service to use, quality of service measurements like the accuracy or reliability of a service need to be known. Users do not want third parties to have statistics on how and where they used services. Therefore the collaboration needs to be anonymous. This project implements a model of event-based context-aware service collaboration on a publish/subscribe basis. We compare different implementation designs, with focus on anonymity and quality of service of the services.

title: Coordinating knowledge to improve optical music recognition

authors: McPherson, John

abstract: Optical Music Recognition (OMR) is the process of automatically processing and understanding an image of a music score. This process involves various distinct phases to transform the image into primitive shapes, musical objects, and ultimately into a syntactic model representing the music's semantics. In general, OMR systems have performed these tasks in a linear sequence, so that the output of one component is the input to the next. However, this means that processing errors that occur in one of the tasks propagate through the system, and often when the error is eventually detected it is too late to reconsider the decisions leading to the incorrect classification or information. 
This thesis describes how OMR can be improved by modifying the recognition process from a sequence of linear tasks to a collection of modules that coordinate the information extracted from the data. Methods for_ data representation and controlling the system's flow of execution are investigated, and a practical implementation of such a system is described. This system has a message-passing design for providing contextual information from one module to another, such as suggesting possible classifications for an object. These messages are used to aid decision-making and to correct faulty decisions. This helps the system to adapt to a particular score while processing the image, increasing accuracy. 
This system is designed to aid in the research and evaluation of algorithms to achieve the above aims; therefore it is straightforward to modify various aspects of the system's behaviour, such as adding support for different music symbols. Examining the implemented system's behaviour clearly shows that this coordinated approach can correct many errors and can even identify some objects by only using syntactic information, based on the surrounding objects.

title: Exploring the experiences of young Māori mothers

authors: Shepherd, Cindy-Joe Theresa Aroha

subjects: Young Māori mothers

abstract: This thesis explores the lived experiences of three young Māori mothers (aged 16 
years old) in Aotearoa, New Zealand, focusing on their strengths, challenges, and resilience. 
By employing a Kaupapa Māori methodological framework, the research aims to reframe 
narratives about young Māori mothers towards a strengths-based perspective, advocating for 
protection and nurturing Māori whakapapa. Using qualitative methods, the study explores the 
pūrākau (stories) of three young Māori mothers attending a teen parent unit in Waikato. 
The study highlights how, by living within both individualistic and collective realms, 
these young mothers actively challenge stigma, assert their worth, and develop unique 
underlying strengths. The findings, structured around emergent themes from their collective 
experiences, reveal a dichotomy: these young mothers must navigate the individualistic 
pressures and high expectations of motherhood while also drawing strength from collective 
responsibilities upheld within their whānau and supportive community services. Despite 
facing significant societal stigma and systemic barriers, the mothers demonstrate immense 
strength. Their resilience is grounded in whānau connections, proactive self-care, and 
engagement with taiao, wairua, and tino rangatiratanga—processes that also support 
intergenerational healing. 
This research underscores the importance of culturally responsive support systems 
that honour Indigenous knowledge and collective well-being. It offers insights for reorienting 
policy and practice to empower young Māori mothers, recognising their tino rangatiratanga 
and transformative agency by embracing their multifaceted realities.
