title: Instrumentation of environment lab filter columns, settling tanks and flocculators

authors: Luo, Weiyang

subjects: Water

abstract: This project was focused on the installation of three water purification systems in the environmental lab of the University of Waikato. Each system consists of a flocculator, a settling tank(clarifier) and a filtration column. The settling tanks were different from each other, one conventional, one laminar and one hopper-bottom clarifier.
The systems were then to be linked with instrumentation to measure and control the purification process in Arduino. The instrumentation included 
•	One flowmeter
•	Two pH meters
•	Two Turbidity sensors
•	One zeta potential meter
Turbidity meters at the inlet to the coagulation and flocculation system, after the coagulation and flocculation, after the clarifiers and after the filters.
The instrumentation was also required to log their reading so students could collect and analyse the data.
The instruments required for the project were purchased with a budget. Prior to the purchase, a list of all items to be purchased was made with comparison on the specification as well as the price. 
A P&ID diagram was made showing the schematic relations between instruments and the equipment.
Once installation of the system was complete, calibration of the sensors were conducted before the runs of the system, whereupon data was collected and analysed.

title: Capturing Situational Context in an Augmented Memory System

authors: Alallah, Jehan Shoie

abstract: Bookmarking a moment is a new approach being introduced to capture past experience and insert information into an augmented memory system. This idea is inspired from the concept of the bookmark in web browsers. Semi-automatic bookmarking different moments when time is limited and revisiting these moments before inserting them into an augmented memory system will help people to remember their past experience. An exploratory study was conducted to discover and shape the design requirements for a system called CatchIt. It aims to understand end-users’ needs to capture their personal experience, which is an important and complex issue in the case of capture and access of personal experiences. CatchIt is a system to bookmark the significant moments during the day before enriching them, and entering them into the augmented memory system called Digital Parrot. The conceptual design of CatchIt will be the main aim of this study. The primary requirements were derived from the scenarios and analysis of the findings of five different study stages were designed to inspect these: unobserved field visit, shadowing, using indictors, Wizard of Oz and using technology. Thirty participants were involved in field visit, survey and follows up interview. Each stage had different tasks to be performed and the findings of each stage contributed to understanding different parts of user needs and system design requirements. The results of this study indicated the system should automatically record the context information, especially the time and location since they were typically neglected by the participants. Different information such as textual and visual information should be manually recorded based on the users’ setting or situations. A single button is a promising input mechanism to bookmark a moment and it should be fast and effort- less. The result showed no clear correlation between learning style and type of the information that had been captured. Also, we found that there might be a correlation between passive capture and false memories. All these findings were used to provide a foundation for further work to implement the bookmark system and evaluate this approach. Some issues raised in this study need further research. The work will contribute to a greater understanding of human memory and selective capture.

title: New Zealand army chaplains at war : 2 NZEF 1939 - 1945

authors: Glen, Frank

abstract: This thesis investigates the motivations to engage in, and the pastoral and sacramental work of, the 1939-45 World War Two chaplains of the Second New Zealand Expeditionary Force, and it explores the theological framework, and theology in which such chaplaincy was carried out. It concludes by noting significant factors and issues of concern to chaplains and their churches in respect of the transition from war to peace.

Historical models of military chaplaincy are found in Constantine’s Roman Empire of 312-337CE, the Christian Crusades of 1096-1291, and the later British Empire. Features of these models provide a tool for understanding and interpreting many aspects of the work and role of the military chaplains of this study. The impact of Christian pacifism is considered, as it is one of the influences which came to bear upon the decision of some clergy who enlisted as chaplains.

Chaplains were recruited from eight denominations and they demonstrated a common pastoral concern for all who were engaged in the various theatres of war. Through the introduction of the concept of ecumenical unit chaplaincy, the battalion became the padre’s parish where he conducted worship, exercised pastoral skills, read the liturgies and preached the Gospel. This became the corner-stone of an ecumenical chaplaincy which developed throughout the war years. Despite the exigencies of war a Bible Class network, church parades - both voluntary and compulsory - and a wide range of religious activities contributed to a spiritual programme which met the needs of a largely nominal Christian 2NZEF.

There emerged from the experience of worship within the 2NZEF a pragmatic ecumenical approach to many aspects of chaplaincy, including in particular the practice, at least for Protestants, of inter-communion. Roman Catholic practice and theological understanding of the Eucharist was enriched by a particular New Zealand contribution. The isolation of the Pacific theatre, coupled with the maturing of the Chaplain’s Department through the Middle East experiences, resulted in a heightening of ecumenical development within the 3rd Division chaplaincy.

The chaplain’s skills in pastoral matters were required to maintain morale, cope with death, wounding and captivity. They are defined first from a military perspective and then examined from a biblical viewpoint. It is primarily in reference to chaplains’ skills associated with the battlefield context, although other situations are included, that issues of pastoral ministry are identified and discussed. The Maori chaplains’ task is discussed in reference to the tohunga of pre-Christian times. Unlike their Pakeha (European) associates. Maori chaplains had access to individuals of influence within New Zealand Maori politics, a factor which was of particular significance.

Almost all chaplains had a belief in the natural justice of World War Two and this thesis will suggest they believed that not to have embarked upon war would have led to infinitely more serious problems for both civilization and the Christian Church. Throughout the war years there was an identified and distinct implicit theological framework which underwrote their attitudes and actions. Their opinions, theological framework and ideology, regarding the war arose both from the ministerial duties they performed and their battlefield experience of war itself.

The model of New Zealand chaplaincy is defined and compared with the classical models noted at the beginning of the thesis. At the end of the war, the 2NZEF Chaplains’ Department held a series of Leadership Schools. These Schools, involving laymen of all denominations. addressed a series of transitional religious and social issues, the outcomes of which were to develop over the decades following WW2. The concluding chapter summarizes a Theology of Chaplaincy which has developed from the foregoing study.
