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: Efficient data stream classification via probabilistic adaptive windows

authors: Bifet, Albert

subjects: computer science

abstract: In the context of a data stream, a classifier must be able to learn from a theoretically-infinite stream of examples using limited time and memory, while being able to predict at any point. Many methods deal with this problem by basing their model on a window of examples. We introduce a probabilistic adaptive window (PAW) for data-stream learning, which improves this windowing technique with a mechanism to include older examples as well as the most recent ones, thus maintaining information on past concept drifts while being able to adapt quickly to new ones. We exemplify PAW with lazy learning methods in two variations: one to handle concept drift explicitly, and the other to add classifier diversity using an ensemble. Along with the standard measures of accuracy and time and memory use, we compare classifiers against state-of-the-art classifiers from the data-stream literature.

title: Using the curriculum guidelines for the teaching and learning of te reo Māori in Years 1 - 13 of New Zealand schools to create lessons for young learners

authors: Diane, Johnson

subjects: New Zealand

abstract: In 2009, The New Zealand Ministry of Education published curriculum guidelines for te reo Māori in Years 1 - 13 of English-medium New Zealand schools, that is, from age 5 upwards. These guidelines recommend a communicative approach to the teaching and learning of te reo Māori. In this article, we discuss communicative approaches and provide examples of ways in which teachers can design communicative language lessons that are appropriate for very young learners, lessons that are not only fun but also effective in developing genuine communicative competence in te reo Māori.
