Analysis Of A Model For The Treatment Of Wastewater By The Activated Sludge Process, Simon D. Watt, Harvinder S. Sidhu, Mark I. Nelson Jan 2006

Analysis Of A Model For The Treatment Of Wastewater By The Activated Sludge Process, Simon D. Watt, Harvinder S. Sidhu, Mark I. Nelson

Faculty of Informatics - Papers (Archive)

We investigate a model for the treatment of wastewater in the activated sludge process. This process is based on the aeration of waste water with flocculating biological growth, followed by the separation of treated waste water from biological growth. Part of this growth is then wasted, and the remainder is returned to the system. The wastewater reactor is assumed to be well mixed, so the mathematical formulation for this process can be represented by a continuously stirred tank reactor with recycle. This system is analysed by combining steady-state analysis with path-following techniques. In practice, wastewater is treated by a sequence …

Clinician optimism is an important factor in achieving treatment outcomes in psychotherapy. Currently there are no measures of mental health clinician optimism which report substantial psychometric validation. This study sought to assesses the validity and reliability of the Therapeutic Optimism Scale (TOS). 223 mental health clinicians working in a range of clinical settings were administered the TOS and convergent and discriminate validity were established. Test-retest reliability was established over a period of one month. The Therapeutic Optimism Scale was found to achieve acceptable reliability (Chronbach's alpha = .68) and yielded consistent scores over a one month period (r = .68, …


Mathematical Analysis Of Self-Heating In Compost Piles, Harvinder S. Sidhu, Mark I. Nelson, Nadeem Ansari, Xiao Dong Chen Jan 2006

Mathematical Analysis Of Self-Heating In Compost Piles, Harvinder S. Sidhu, Mark I. Nelson, Nadeem Ansari, Xiao Dong Chen

Faculty of Informatics - Papers (Archive)

We model the increase in temperature in compost piles or landfill sites due to micro-organisms undergoing exothermic reactions. The model incorporates the heat release due to biological activity within the pile and the heat release due to the oxidation of cellulosic materials. The heat release rate due to biological activity is modelled by a function which is a monotonic increasing function of temperature over a particular range and followed by a monotone decreasing function of temperature. This functionality represents the fact that micro-organisms die or become dormant at high temperatures. The heat release due to the oxidation reaction is modelled …


The Design And Analysis Of Multi-Phase Plant Breeding Experiments, A B. Smith, P Lim, Brian R. Cullis Jan 2006

The Design And Analysis Of Multi-Phase Plant Breeding Experiments, A B. Smith, P Lim, Brian R. Cullis

Faculty of Informatics - Papers (Archive)

Despite the importance of selection for quality characteristics in plant improvement programmes, literature on experimental design and statistical analysis for these traits is scarce. Most quality traits are obtained from multi-phase experiments in which plant varieties are first grown in a field trial then further processed in the laboratory. In the present paper a general mixed model approach for the analysis of multi-phase data is described, with particular emphasis on quality trait data that are often highly unbalanced and involve substantial sources of non-genetic variation and correlation. Also detailed is a new approach for experimental design that employs partial replication …


Tacit Assumptions In The Analysis Of A Creative Economy, Dr. Eduardo Pol Jan 2006

Tacit Assumptions In The Analysis Of A Creative Economy, Dr. Eduardo Pol

Faculty of Commerce - Papers (Archive)

The formal models of a creative economy revolve around these tacit assumptions: (1) all innovations are equally important for economic growth (equipollent innovation); (2) all innovations occur in one sector only (confined innovation); and (3) there are no innovatory discontinuities ( unruffled innovation).

Assessment Of Spatial Analysis Techniques For Estimating Impervious Cover, Steven Roso, Michael J. Boyd, Laurie A. Chisholm Jan 2006

Assessment Of Spatial Analysis Techniques For Estimating Impervious Cover, Steven Roso, Michael J. Boyd, Laurie A. Chisholm

Faculty of Engineering - Papers (Archive)

Impervious cover proportion is recognised as an important parameter in hydrologic modelling. Recent advances in the spatial sciences provide new capabilities for estimation of this value. This paper describes an assessment of seven estimation techniques, including human and computer based methods requiring a range of different input data and skill levels. In order to quantify the value of any gain in accuracy, the results from each method were applied to a real catchment using event based (WBNM) and continuous simulation (MUSIC) hydrologic models. The results showed that use of high resolution satellite imagery enabled the most accurate measurements of impervious …

This paper presents a new analysis algorithm to carry out profile measure- ment with low computational complexity and less noise-sensitivity. Firstly, a discrete cosine transform (DCT) based representation method is introduced to express the height distribution of the three-dimensional surface. Then, a novel shift estimation algorithm, called DCT based shift estimation (DCT-SE) is presented to reconstruct three-dimensional object surfaces by using the proposed expression and the generalized analysis model. The advantage of DCT-SE is that without loss of measurement precise it provides lower computational complexity to implement three-dimensional reconstruction from distorted fringe patterns and at the same time survives from …

Professional learning is an important process in enabling teachers to update their pedagogical knowledge and practices. The use of online technologies to support professional learning has a number of benefits in terms of flexibility and scalability. However, it is not clear how well the approach impacts on teachers’ classroom practices. This paper outlines a research study conducted on behalf of a state-based Department of Education to evaluate the transfer of professional learning from online modules about the integration of ICT to the practices of K-12 classroom teachers.


Gait Analysis Of Low-Cost Flexible-Shank Transtibial Prostheses, Winson Lee, Ming Zhang, Peggy Chan, David A. Boone Jan 2006

Gait Analysis Of Low-Cost Flexible-Shank Transtibial Prostheses, Winson Lee, Ming Zhang, Peggy Chan, David A. Boone

Faculty of Engineering and Information Sciences - Papers: Part A

The latest lower-limb prosthetic designs have been incorporated with dynamic elastic response (DER) components to enhance prosthesis flexibility, which are suggested to be beneficial to gait. Although DER prosthetic. feet are preferred by most transtibial amputees and their benefits to gait are supported by some biomechanical studies, many are still utilizing the simple conventional solid ankle cushioned heel (SACH) designs because of the lower cost. The monolimb, a transtibial prosthesis with the socket and the shank molded from a single piece of thermoplastic material, perhaps is an alternative to DER feet for providing flexibility at the shank. In addition to …


Explicit Dynamic Fem Analysis Of Multipass Vertical-Horizontal Rolling, Hai-Liang Yu, Xiang-Hua Liu, Xian-Ming Zhao, Di Wu, Y Kusaba Jan 2006

Explicit Dynamic Fem Analysis Of Multipass Vertical-Horizontal Rolling, Hai-Liang Yu, Xiang-Hua Liu, Xian-Ming Zhao, Di Wu, Y Kusaba

Faculty of Engineering and Information Sciences - Papers: Part A

Three passes of plate rolling during vertical-horizontal rolling process are simulated with explicit dynamic finite element method and updating geometric method. The equivalent strain and stress fields, and shape change at the head and tail of slab during rolling are obtained. The calculated result of the shape at the head and tail of slab is in good agreement with the measured one. The explicit dynamic finite element method and updating geometric method can be used effectively to analyze the multipass vertical-horizontal (V-H) rolling process. © 2006 Central Iron and Steel Research Institute.


Developing Familiarity With Learning Design Tools Through Subject Analysis, Christine A. Brown Jan 2006

Developing Familiarity With Learning Design Tools Through Subject Analysis, Christine A. Brown

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

The application of quality processes to tertiary teaching can result in a more team-based approach to course curriculum planning, the instructional design of individual subjects or units, the learning support associated with subject implementation and subsequent evaluation. The "art" of teaching requires more explicit communication within and across different teams that may be involved in each stage. Learning designs provide tools for design teams to map out learning environment attributes such as resources, tasks, people and interactions. Experienced teaching academics, unfamiliar with such tools, require orientation to them to achieve their communication potential. One way to introduce learning design models …

Between The Lines: An Analysis Of The Language Of Indonesian Reporting Of Military Clashes In Aceh, Philip Kitley

Faculty of Arts - Papers (Archive)

[extract] Kompas Cyber Media is the online presence of the leading Indonesian daily Kompas and it was on the small screen that I first read about the kidnapping on 29 June, 2003 of television journalist Ersa Siregar, camera operator Ferry Santoro, their driver Rahmatsyah and two female passengers, sisters Safrida and Soraya. The online version of this drawn out story of reporters hostage to the Free Aceh Movement (Gerakan Aceh Merdeka, GAM) stripped down the news stories that appeared in the broadsheet. I was struck by the more than usually limited information value of the hostage headlines and stories from …
