title: Design of a processor to support the teaching of computer systems

authors: Pearson, Murray W.

subjects: computer science

abstract: Teaching computer systems, including computer architecture, assembly language programming and operating system implementation, is a challenging occupation. At the University of Waikato this is made doubly true because we require all computer science and information systems students study this material at second year. The challenges of teaching difficult material to a wide range of students have driven us to find ways of making the material more accessible. The corner stone of our strategy for delivering this material is the design and implementation of a custom CPU that meets the needs of teaching. This paper describes our motivation and these needs. We present the CPU and board design and describe the implementation of the CPU in an FPGA. The paper also includes some reflections on the use of a real CPU rather than a simulation environment. We conclude with a discussion of how the CPU can be used for advanced classes in computer architecture and a description of the current status of the project.

title: The potential of harakeke fibre as reinforcement in polymer matrix composites including modelling of long harakeke fibre composite strength

authors: Le, Tan Minh

abstract: Mechanical properties of aligned long harakeke fibre reinforced epoxy with different fibre contents were evaluated. Addition of fibre was found to enhance tensile properties of epoxy; tensile strength and Young's modulus increased with increasing content of harakeke fibre up to 223 MPa at a fibre content of 55 wt% and 17 GPa at a fibre content of 63 wt%, respectively. The flexural strength and flexural modulus increased to a maximum of 223 MPa and 14 GPa, respectively, as the fibre content increased up to 49 wt% with no further increase with increased fibre content. The Rule of Mixtures based model for estimating tensile strength of aligned long fibre composites was also developed assuming composite failure occurred as a consequence of the fracture of the lowest failure strain fibres taking account porosity of composites. The model was shown to have good accuracy for predicting the strength of aligned long natural fibre composites.

title: Defence not defiance: The shaping of New Zealand’s volunteer force

authors: Clayton, Garry James

subjects: New Zealand Army history

abstract: In the latter half of the nineteenth century and the first decade of the twentieth New Zealand's land defences were primarily the responsibility of its Volunteer Force. This Force over a period of fifty-two years evolved from ill-considered vigilante bands to a well organised and disciplined Army. This thesis examines the evolution of this Volunteer Army in chronological sequence concentrating on the factors which shaped and developed it.
The preface provides a brief outline of this study on New Zealand's Volunteer Force. The thesis then presents the history of the Force in eight chapters. These chapters are in four basic divisions. The first section, of three chapters. examines the origins of the Force, its role in the New Zealand Wars and its subsequent development in the period of tenuous peace during the 1870's . The second section, comprising of two chapters only, examines the transformation of the Volunteers from a military body which primarily looked inward. into a Force which concentrated on protecting the nation's main ports. The third section , also comprising two chapters , then views the development of this coastal protection Force into a Colonial Army, able and willing to provide for the nation's own security as well as expeditionary units to· serve with the British Imperial Forces ·. The last Section, of one Chapter only, concentrates on the demise of Volunteering and the moves to compulsory military training. The conclusion then draws together the analytical threads of the thesis. 
As the thesis is extensive in its coverage of time, it is only possible to outline the very nature of Volunteering. It will be for Regimental Historians to show the uniqueness of each of the 658 different units that comprised the New Zealand Volunteer Force over its fifty-two years of existence. What this broad survey does do, however, is provide a unique window for the examination of the development of an embryonic Colonial Army in the context of a developing nation.
