title: An architecture for secure provisioning and usage of IOT services

authors: Mustafa, Rashid

abstract: The growth in the internet of things plays a central role in the future internet having a common platform for a complex network of computers, wired and wireless sensors, actuators and radio frequency identification devices.  Our simplified view of this complex network is of a ‘network that provides various services’; let’s call it the internet of services. There is though a lack of a platform that can bring together the services offered by the internet of things/internet of services and the future user of these services. In this thesis, an architecture has been proposed for providing secure services to connected users. We propose a layered architecture that has an application layer, a service layer and a sensing-network layer to accommodate the requirements of the internet of services in a timely and effective manner. 
In this architecture, the end to end data communication security of the internet of services has been taken into consideration. A web security interface has been introduced, which provides security for user credentials. This interface is introduced in the application layer to protect and ensure data communication security using a single sign on. We have proposed a node to node communication security solution after considering the vulnerabilities and threats around connecting a future integrated service. We have designed and evaluated our architecture by performing a range of experiments. These experiments were conducted using database connection round trip time, total execution code round trip time and average query round trip time to compare the services that were designed on different programming platforms.

title: Keratin and S100 calcium-binding proteins are major constituents of the bovine teat canal lining

authors: Smolenski, Grant A.

abstract: The bovine teat canal provides the first-line of defence against pathogenic bacteria infecting the mammary gland, yet the protein composition and host-defence functionality of the teat canal lining (TCL) are not well characterised. In this study, TCL collected from six healthy lactating dairy cows was subjected to two-dimensional electrophoresis (2-DE) and mass spectrometry. The abundance and location of selected identified proteins were determined by western blotting and fluorescence immunohistochemistry. The variability of abundance among individual cows was also investigated. Two dominant clusters of proteins were detected in the TCL, comprising members of the keratin and S100 families of proteins. The S100 proteins were localised to the teat canal keratinocytes and were particularly predominant in the cornified outermost layer of the teat canal epithelium. Significant between-animal variation in the abundance of the S100 proteins in the TCL was demonstrated. Four of the six identified S100 proteins have been reported to have antimicrobial activity, suggesting that the TCL has additional functionality beyond being a physical barrier to invading microorganisms. These findings provide new insights into understanding host-defence of the teat canal and resistance of cows to mastitis.

title: Case roles / relations and discourse relations: A Maori language-based perspective

authors: Whaanga, Hēmi

subjects: case grammar

abstract: The overall aim of this research project is to explore case roles/ relations and discourse relations (referred to in this thesis as 'intra-propositional relations' and 'interpropositional relations' respectively) from the perspective of the Maori language. 
The thesis begins with an outline of the scope of the research and the approaches and methods used (Chapter 1). This is followed by a critical review of selected literature on case roles/ relations (intra-propositional relations) (see Chapter 2) and discourse relations (inter-propositional relations) (see Chapter 3) where it is noted that some of the relational theories and models appear to lack descriptive and/or explanatory adequacy. 
In Chapter 4, two models (an intra-propositional relational model and an interpropositional relational model) are developed on the basis of the critical review in Chapters 2 and 3, and these models are applied to a written corpus of Maori language texts, the primary aim being to track the ways in which intra-propositional and interpropositional relations are signalled in Maori. 
In Chapter 5, l supplement the corpus-based findings reported in Chapter 4 by reexamining the findings of two earlier studies from the perspective of the models introduced in Chapter 4. One of these earlier studies, reported in the early 1980s, is concerned with the distribution of prepositions in Maori in relation to case roles/ relations (intra-propositional relations); the other, produced much more recently (in 2001) is concerned with the signalling in Maori of a selection of what are referred to in that Work as 'semantico-pragmatic relations' (inter-propositional relations). 
Chapter 6 provides an overview of the research and a summary of the findings, together with an indication of its limitations, possible areas of application, and suggestions for future research.
