title: Evolving concurrent Petri net models of epistasis

authors: Mayo, Michael

subjects: computer science

abstract: A genetic algorithm is used to learn a non-deterministic Petri netbased model of non-linear gene interactions, or statistical epistasis. Petri nets are computational models of concurrent processes. However, often certain global assumptions (e.g. transition priorities) are required in order to convert a non-deterministic Petri net into a simpler deterministic model for easier analysis and evaluation. We show, by converting a Petri net into a set of state trees, that it is possible to both retain Petri net non-determinism (i.e. allowing local interactions only, thereby making the model more realistic), whilst also learning useful Petri nets with practical applications. Our Petri nets produce predictions of genetic disease risk assessments derived from clinical data that match with over 92% accuracy.

title: Development of a building integrated photovoltaic/thermal solar energy cogeneration system

authors: Anderson, Timothy Nicholas

subjects: photovoltaic

abstract: Using renewable energy sources for onsite cogeneration from structural building elements is a relatively new concept and is gaining considerable interest. In this study the design, development, manufacturing and testing of a novel building integrated photovoltaic/thermal (BIPVT) solar energy cogeneration system is discussed.
Adhesives (ADH), resistance seam welding (RSW) and autoclaving (ATC) were identified as the most appropriate for fabricating BIPVT roofing panels. Of these manufacturing methods ADH was found to be most suitable for low volume production systems due to its low capital cost. A prototype panel, fabricated using ADH methods, exhibited good thermal performance. It was also shown that BIPVT performance could be theoretically predicted using a onedimensional heat transfer model and showed excellent agreement with experimental data. The model was used to suggest further design improvements. Finally, a transient simulation of the BIPVT was performed in TRNSYS and is used to illustrate the benefits of the system.

title: Māori and bicultural positions: Professional development programme for Resource Teachers Learning and Behaviour

authors: Glynn, Ted

subjects: Maori

abstract: The Ministry of Education has introduced a new and far-reaching policy initiative,
Special Education 2000. One component of this policy is the provision of
professional development for approximately 700 Resource Teachers [Learning and
Behaviour (RTLB)]. These resource teachers will help schools to meet the needs
of students experiencing mild to moderate learning and behavioural difficulties.
An important aim of the professional development programme is to prepare RTLB
to improve the quality of support to teachers of Māori students in conventional and
Māori medium classes. The programme consists of four courses, one introducing
key concepts, one focussed on class-wide interventions, one focussed on school
and community, and the fourth being a professional practice folio. This paper
describes the Māori and bicultural content of the first two courses within the RTLB
programme. It assesses the extent to which the programme addresses critical
questions (Bishop, 1994; Bishop, 1996) relating to the ownership and control of
Māori content included in the first two courses.
