title: PIWeCS: enhancing human/machine agency in an interactive composition system

authors: Whalley, Ian

abstract: This paper focuses on the infrastructure and aesthetic approach used in PIWeCS: a Public Space Interactive Web-based Composition System. The concern was to increase the sense of dialogue between human and machine agency in an interactive work by adapting Paine's (2002) notion of a conversational model of interaction as a ‘complex system’. The machine implementation of PIWeCS is achieved through integrating intelligent agent programming with MAX/MSP. Human input is through a web infrastructure. The conversation is initiated and continued by participants through arrangements and composition based on short performed samples of traditional New Zealand Maori instruments. The system allows the extension of a composition through the electroacoustic manipulation of the source material.

title: An examination of genres and text-types in written Māori discourse: Analysis and pedagogic implications

authors: Houia-Roberts, Ngaere

abstract: The overall aim of this research project is to determine what genres and text-types are most commonly required of students at upper secondary and tertiary levels in Māori-medium educational settings (Chapter 4), and to further determine, in relation to the analysis of authentic texts written by educated users of the language who have a high level of proficiency, how such genres and text-types are typically structured (Chapters 5 and 6). It is intended that this information should provide teachers and students with a solid foundation for the development of the skills required to create written texts in Māori that are structured in ways that are as close as possible to authentic discourses written by educated and highly proficient users of the language (Chapter 7). The thesis begins by providing some background to the research and outlining the primary aims, research questions and research methods (Chapter 1). This is followed by a critical review of some general landmark publications in the area of genre and text-type (Chapter 2).More pedagogically-centred, process-oriented approaches to genre and text-type are then critically reviewed in the context of the design of the model which underpins the analyses conducted in the following chapters.

title: High power linear AC Electronic Load for testing UPS Systems

authors: Jinadasa, Muthunacharige Damayanthi Chandani Srimathi Kumari

subjects: Electronic load

abstract: Concept of a series bipolar transistor array for AC power control is already developed. However non-linearity issues, high power capability with load sharing at high voltages and digital control with better transient performance were not adequately adopted in early-developed stages.

This thesis is a description of the design approach of digitally controllable linear 230V/50 Hz AC line voltage capable electronic load with predictable characteristics based on spice simulation. The BJT array used in this project provides high power dissipation capability and uniform voltage and power distribution across the individual transistors. A set of optoisolators are used to have electrical isolation between power stage and digital control circuits. A Zilog Z8Encore! 64K series development kit is used in controlling the circuit.
