Modelling the stability and efficiency of ring spinning. This research will benefit the animal fibre industry, particularly the multi-billion dollar wool industry. Low spinning efficiency adds a significant cost to the conversion of animal fibres into textile products, which reduces the competitive position of these natural fibres. The proposed research will lead to improvement in the efficiency of ring spinning. It has been estimated that a 1% improvement in spinning efficiency will add about $ ....Modelling the stability and efficiency of ring spinning.

Low spinning efficiency adds a significant cost to the conversion of animal fibres into textile products, which reduces the competitive position of these natural fibres. The proposed research will lead to improvement in the efficiency of ring spinning. It has been estimated that a 1% improvement in spinning efficiency will add about $16 million to the wool industry alone. Read moreRead less
Modelling and minimising energy consumption in ring spinning. Australia's 4-billion dollar natural fibre production is spun into yarns via ring spinning mainly. A major drawback of this spinning system is its high energy consumption. This project will examine, theoretically and experimentally, the key factors contributing to energy consumption in ring spinning. It will generate new knowledge on the relationship between yarn hairiness and the air drag on a rapidly rotating yarn package and on a b ....Modelling and minimising energy consumption in ring spinning. Australia's 4-billion dollar natural fibre production is spun into yarns via ring spinning mainly. A major drawback of this spinning system is its high energy consumption. This project will examine, theoretically and experimentally, the key factors contributing to energy consumption in ring spinning. It will generate new knowledge on the relationship between yarn hairiness and the air drag on a rapidly rotating yarn package and on a ballooning yarn, and predict how this air drag affects the energy consumption during package build-up in ring spinning. This will lead to ways of minimising energy consumption in this most important spinning process.Read moreRead less
Real time optimisation by extremum seeking control and learning control. Optimal control technology provides the systematic design of systems that exhibit optimal behaviour, such as maximal productivity, best efficiency, minimal cost and best quality. Real time optimisation finds the solution of the optimal control in real time, relaxing requirements on the system knowledge. The proposed research will build on Australia's well-established strength in control and optimisation, and aim to establis ....Real time optimisation by extremum seeking control and learning control.

Extremum seeking control: analysis, design and applications. Optimal control is one of the central pillars in the field of automatic control, but is prevented from use in many engineering applications due to the computational complexity and system knowledge requirements typically associated with the technique. Extremum seeking promises the performance of an optimal approach, but with the benefit of real time implementation and very relaxed requirements on the system knowledge. Through improved u ....Extremum seeking control: analysis, design and applications.

What is the spatial and environmental distribution of phylogenetic diversity in the Australian biota? Almost nothing is known about the geographic distribution of phylogenetic relationships across Australia at fine resolutions of the order of tens of kilometres. The aim of this research is to map the spatial patterns of phylogenetic diversity in the Australian biota and identify possible environmental controls over them. We will analyse five disparate groups at a spatial resolution that is ord ....What is the spatial and environmental distribution of phylogenetic diversity in the Australian biota? Almost nothing is known about the geographic distribution of phylogenetic relationships across Australia at fine resolutions of the order of tens of kilometres. The aim of this research is to map the spatial patterns of phylogenetic diversity in the Australian biota and identify possible environmental controls over them. We will analyse five disparate groups at a spatial resolution that is orders of magnitude finer than previous research, analysing their relationship with possible environmental controls using advanced spatial analysis methods. The knowledge we will generate about the spatial distribution of these relationships is essential to understand and conserve Australia's unique biodiversity.Read moreRead less
