The purpose of this study is to provide further empirical evidence for the Australian case. It differs from previous studies in a number of respects. For example, the process by which expectations are generated differs from the processes adopted in previous studies. It also has two additional aims which differentiate it from earlier studies. First, it considers the validity of aggregating the demands for certain monetary assets into a single demand for money function. Most of the studies mentioned above deal with a single monetary aggregate; Lewis and Wallace consider only the demand for savings deposits. This study reports separate equations explaining the demand for notes and coin and current (cheque) deposits. These assets have been chosen because they possess the common characteristic that they can be converted into cash on demand. Secondly, an aspect of the Australian banking system which has been ignored in previous studies is examined in this paper. Australian trading banks lend on the overdraft system and at any point in time there is a substantial amount available to borrowers in the unused portions of their overdraft accounts. It has frequently been argued that the value of this store of liquidity should be included in measures of the money supply. This proposition is tested by the equations reported in this paper.

Professor James Henry ('Jim') Michael 1920-2001 was elected to the Australian Academy of Science in 1973. Born in Port Augusta, Jim saw active service during the Second World War. Returning to Adelaide, he completed a PhD in pure mathematics and began a distinguished career as an international expert in mathematical analysis. As well as being a mathematician, Jim was a keen golfer and shooter. Jim is remembered as a quiet, gentle man of few words but great integrity. A devoted family man, he is survived by his wife Pat, his daughter Mary Jane, his son Philip and his two grandchildren Ian and Tim Michael. [ABSTRACT FROM AUTHOR]

Locata Corporation's positioning technology 'Locata' is a terrestrial-based RF-ranging technology that provides high accuracy position solutions using a network (LocataNet) of time synchronised pseudolite-like transceivers (LocataLites). This technology provides centimetre level accurate position solutions for static positioning using carrier phase measurement data which provides an advantage over other technology for monitoring structural movement in many applications. The Locata network can be deployed in such a configuration around a structure that optimal network geometry could be ensured despite site constraints. This paper describes the first deformation trial using Locata technology carried out at Tumut Pond Dam, in the state of New South Wales, Australia. This trial was run for 22 hours and yielded millimetre-level precision for horizontal positions, and centimetre-level vertical precision for all observed epochs. The accuracy of the coordinate solutions was at the few millimetre level with standard deviations of 2.5 mm, 2.1 mm and 18 mm for the east, north and height components respectively. The position solutions were generated by an iterative least squares estimation process of Locata carrier phase observations per epoch. Then mean of sixty seconds coordinate solutions was used as input for a Kalman filter. Standard deformation detection methods were applied. No significant displacement was observed during this trial.

This viewpoint paper presents the writer's opinion that while the use of problem solving as the core method for learning mathematics is valid and reasonable in secondary schools (where students generally possess the necessary prior skills and strategies) there are many obstacles to applying the same method in primary schools, particularly in the early years. In addition to acquiring a conceptual understanding of number, young learners - and older students with learning difficulties - need to develop automaticity in recalling basic number facts and in applying computational procedures. To do this they require both active experience with number relationships and direct teaching with guided and independent practice. There is no hard evidence that most students achieve adequate mastery of basic numeracy skills simply by engaging in exploratory problem solving. Drawing on the relevant literature the writer identifies and analyses the potential difficulties associated with using such an approach as a main method for teaching primary mathematics.

This paper describes the mathematical formulation and modelling issues of a computational fluid dynamics (CFD) model of a 375 MW utility furnace. This tangentially-fired furnace is fuelled by high moisture content brown coal from coal mines at Latrobe Valley in Victoria, Australia. The influences of different turbulence models, particle dispersion, and radiation models on the CFD prediction are investigated. Two turbulence models, standard k-ε model and Shear-Stress Transport (SST) model, provide similar predictions that are in good agreement with the plant data. The effect of particle dispersion on the prediction is found to be insignificant for this high-volatile brown coal. The predicted wall incident radiation flux based on two radiation models, namely, discrete transfer (DT) model and P-1 model are compared against power plant measurements. The comparison reveals that the DT model provides good prediction of the radiation profiles, while the P-1 model considerably underpredicts the wall incident radiation flux. [ABSTRACT FROM AUTHOR]
