Overview Of Intense Beam-Driven Relativistic Backward Wave Oscillators And Their Use In High Power Microwave Effects Studies, Chaouki T. Abdallah, C.E. Pizano, G.L. Heileman, M.S. Pattichis

Electrical & Computer Engineering Faculty Publications

We propose mathematical performance measures by which the robustness, imperceptibility and information content of various watermarking methods could be measured. These measures rely in the notion of equivalence in the perceptual domain and some basic information-theoretic concepts. Based on these measures we show that the success of image watermarking heavily depend on the functional form of the human visual system perceptual mask. We also analyse the implication for robust watermarking of some commonly used perceptual masks.

Robust Non-Fragile Lq Controllers: The Static State Feedback Case, Chaouki T. Abdallah, Domenico Famularo, Peter Dorato, Wassim M. Haddad, Ali Jadbabaie

Electrical & Computer Engineering Faculty Publications

This paper describes the synthesis of non-fragile or resilient regulators for linear systems. A general framework for fragility is described using state-space methodologies, and the LQ/H2 static state-feedback problem is examined in detail. We discuss the multiplicative structured uncertainties case, and propose remedies of the fragility problem using an optimization programming framework via matrix inequalities. A special case that leads to a convex optimization framework via linear matrix inequalities (LMIs) will be considered. The benchmark problem is taken as an example to show how special controller gain variations can affect the performance of the closed-loop system.

Precision Farming Protocols. Part 2. Comparison Of Sampling Approaches For Precision Phosphorus Management, David E. Clay, Jiyul Chang, C. Gregg Carlson, Doug Malo, Sharon A. Clay, Mike Ellsbury

Agronomy, Horticulture and Plant Science Faculty Publications

Research is needed to compare the different techniques for developing site‐specific phosphorus (P) recommendations on a field‐wide basis. The objective of this study was to determine the impact different techniques for developing site‐specific P recommendation maps on yield and profitability. Enterprise analysis combined with a crop simulation model and detailed field characterization was used to estimate the value of spatial P information in a system where N was not limiting. The systems evaluated were continuous corn (Zea mays) and corn and soybean (Gfycine max) rotations where sampling and fertilizer applications were applied annually and semi‐annually, respectively. The sampling techniques tested …

Attitudes Of Lower Secondary School Students Toward Social Studies At An Independent School : A Case Study, Diane M. Hobbs

Theses : Honours

There is a dearth of research on student attitudes toward social studies, especially in Western Australian secondary schools. The purpose of this case study was twofold. Firstly it was to determine the attitudes of lower secondary school students toward social studies at one Independent high school in the Perth metropolitan area. Secondly, it was to investigate the factors that influence student attitudes toward social studies. The case study school was selected as a convenience sample. A total of 203 students from Years 8, 9, and 10 completed a questionnaire designed to determine attitudes toward social studies and to identify factors …

Derailed : The Social, Economic And Political Implications Of The Closure Of The Westrail Midland Workshops, Lyla D. Elliott

Theses : Honours

The Westrail Midland Workshops had serviced the Western Australian Government Railway fleet for 90 years when they were closed by the Court Government in 1994. As the State's largest and best equipped industrial establishment employing over 900 workers, the announcement of the closure was unexpected and controversial. The research questions asked in this thesis are: Why did the Workshops close? What were the economic and political issues involved? What attempts were made to modernise the Workshops and improve efficiency, and what were the social and economic effects on the workers? The event took place at a time of changing ethos …

The Applicability Of Stable Carbon Isotope Analysis To Measure The Water Use Efficiency Of Melaleuca Preissiana Populations On The Swan Coastal Plain, Western Australia, Hayley E. Valentine

Theses : Honours

Stable carbon isotope (δ¹³C) analysis is a tool used to understand the water use efficiency (WUE) of plants. The advantage of measuring the carbon isotope composition in plant tissue over other measures of WUE (such as the ratio of photosynthesis to transpiration) is that it provides a time-integrated, rather than an instantaneous measure of plant-water relations. The purpose of this study was to evaluate the applicability of using δ¹³C analysis in natural populations of the fringing tree Melaleuca preissiana based on short and long term sampling methods. There were three components to this study; a controlled, …

The Effect Of Leaf Movement On Algal Epiphytes In Seagrass Meadows, T. R. Reid

Theses : Honours

Artificial seagrass units were used to determine whether seagrass leaf movement influences the biomass, species richness and composition of epiphytic macroalgae on the leaves of seagrasses, and whether the influence of leaf movement is altered by the degree of exposure to water movement and to depth. The influence of leaf movement on epiphytic biomass is important from an environmental management perspective, as there is the potential for epiphytic productivity to be underestimated if leaf movement is reducing the standing crop of epiphytes on seagrass leaves. Two forms of artificial seagrass units were used in three experiments to achieve these objectives; …

Variability, Petrography And Provenance Of Basement Clasts In Core From Crp-2/2a, Victoria Land Basin, Antarctica, F Talarico, S Sandroni, Christopher R. Fielding, C Atkins

Department of Earth and Atmospheric Sciences: Faculty Publications

Distribution patterns, petrography, whole-rock and mineral chemistry, and shape and fabric data are described for the most representative basement lithologies occurring as clasts (granule to boulder grain-size class) from the 625 m deep CRP-2/2A drillcore. A major change in the distribution pattern of the clast types occurs at c. 310 mbsf, with granitoid-dominated clasts above and mainly dolerite clasts below; moreover, compositional and modal data suggest a further division into seven main detrital assemblages or petrofacies. In spite of this variability, most granitoid pebbles consist of either pink or grey biotite±hornblende monzogranites. Other less common and ubiquitous lithologies include …

Chronostratigraphy Of Crp-2/2a, Victoria Land Basin, Antarctica, G S. Wilson, S. M. Bohaty, Christopher R. Fielding, F Florindo, M J. Hannah, David M. Harwood, W C. Mcintosh, T R. Naish, A. P. Roberts, L Sagnotti, R P. Scherer, C P. Strong, K L. Verosub, G Villa, David K. Watkins, P N. Webb, K J. Woolfe

The 624.15 m glaciomarine sedimentary succession recovered in the CRP-2/2A drillcore comprises lower Oligocene (< c. 31 Ma) to lower Miocene (18.5 Ma) strata that are overlain by a thin succession of Pliocene and Pleistocene strata. The age model for the CRP-2/2A drillhole, as presented in this paper, is based on combined microfossil biostratigraphy, ⁴⁰Ar/³⁹Ar ages on volcanic material, ⁸⁷Sr/⁸⁶Sr analyses on mollusc shells, and correlation of a magnetic polarity zonation to the magnetic polarity time scale (MPTS). Between 25.92 and 109.05 metres below sea floor (mbsf), several alternative correlations to the MPTS are possible, all of which suggest that sediment accumulation rates averaged ~180 m/m.y. between unconformities, although actual sedimentation rates may have been higher. Between 109.05 and 306.65 mbsf, the age model is straightforward and average sedimentation rates were much higher …

Three-Dimensional Computer Simulation Of Liquid Drop Evaporation, Mark Korlie

Department of Mathematics Faculty Scholarship and Creative Works

We use molecular dynamics simulation to describe a method that can be used to model liquid drop evaporation. For application, the liquid is taken to be water. Using the properties of the liquid and a Lennard-Jones potential, we derive dynamical equations, which are used to describe the gross dynamical behavior of the liquid-vapor molecular system. The resulting dynamical equations are solved numerically by a time stepping, numerical method. The evaporation of the liquid to the vapor phase is described.

3-D Particle Modeling Of Gas Bubbles In A Liquid, Mark Korlie

Department of Mathematics Faculty Scholarship and Creative Works

We use a molecular aggregate approach and classical, molecular dynamics type formulas to simulate the motion of gas bubbles within a liquid. For application, the liquid is taken to be water while the gas is taken to be carbon dioxide. The resulting dynamical equations are large systems of second-order, nonlinear, ordinary differential equations which are solved by a time-stepping numerical method. The rise of the bubbles and the motion of the water near the bubbles are described and discussed.

Quality Of Service Management For Non-Guaranteed Networks, Tarek Madkour

Archived Theses and Dissertations

The increasing dominance of multimedia communication posed new requirements for the underlying systems. Multimedia data, formally called continuous media, has time constraints that impose real time limitations for their transmission. Certain levels of service, called Quality of Service (QoS), need to be considered when handling continuous media. The present work utilizes QoS concepts for networks that do not have inherent QoS support. The thesis aims at verifying the possibility of having QoS-controlled communication on non-guaranteed networks. A basic QoS architecture is designed where already existing QoS concepts are adapted to work with non-guaranteed networks. The architecture provides the facilities of …

Time Delayed Process Model Parameter Estimation: A Classification Of Techniques, Aidan O'Dwyer

Conference papers

An extensive though scattered literature exists on the estimation of the model parameters of time delayed processes. However, it is possible to identify themes that are common to many of the proposed techniques. The intention of this paper is to provide a framework against which the literature may be viewed.
