Reviews And Syntheses: 210pb-Derived Sediment And Carbon Accumulation Rates In Vegetated Coastal Ecosystems – Setting The Record Straight, Ariane Arias-Ortiz, Pere Masque´, Jordi Garcia-Orellana, Oscar Serrano, Ines Mazarrasa, Nuria Marba, Catherine E. Lovelock, Paul S. Lavery, Carlos M. Duarte

Research outputs 2014 to 2021

Vegetated coastal ecosystems, including tidal marshes, mangroves and seagrass meadows, are being increasingly assessed in terms of their potential for carbon dioxide sequestration worldwide. However, there is a paucity of studies that have effectively estimated the accumulation rates of sediment organic carbon (C_org), also termed blue carbon, beyond the mere quantification of C_org stocks. Here, we discuss the use of the ²¹⁰Pb dating technique to determine the rate of C_org accumulation in these habitats. We review the most widely used ²¹⁰Pb dating models to assess their limitations in these ecosystems, often composed of …

Metabolic And Fatigue Profiles Are Comparable Between Prepubertal Children And Well-Trained Adult Endurance Athletes, Anthony Birat, Pierre Bourdier, Enzo Piponnier, Anthony J. Blazevich, Hugo Maciejewski, Pascale Duche, Sebastien Ratel

Research outputs 2014 to 2021

The aim of this study was to determine whether prepubertal children are metabolically comparable to well-trained adult endurance athletes and if this translates into similar fatigue rates during high-intensity exercise in both populations. On two different occasions, 12 prepubertal boys (10.5 ± 1.1 y), 12 untrained men (21.2 ± 1.5 y), and 13 endurance male athletes (21.5 ± 2.7 y) completed an incremental test to determine the power output at VO_2max (PVO_2max) and a Wingate test to evaluate the maximal anaerobic power (P_max) and relative decrement in power output (i.e., the fatigue index, FI). Furthermore, …

Application Of 3d Delaunay Triangulation In Fingerprint Authentication System, Wencheng Yang, Ahmed Ibrahim, Junaid Chaudhry, Song Wang, Jiankun Hu, Craig Valli

Research outputs 2014 to 2021

Biometric security has found many applications in Internet of Things (IoT) security. Many mobile devices including smart phones have supplied fingerprint authentication function. However, the authentication performance in such restricted environment has been downgraded significantly. A number of methods based on Delaunay triangulation have been proposed for minutiae-based fingerprint matching, due to some favorable properties of the Delaunay triangulation under image distortion. However, all existing methods are based on 2D pattern, of which each unit, a Delaunay triangle, can only provide limited discrimination ability and could cause low matching performance. In this paper, we propose a 3D Delaunay triangulation based …

How Important Is Groundwater Availability And Stream Perenniality To Riparian And Floodplain Tree Growth?, Neil E. Pettit, Raymond H. Froend

Research outputs 2014 to 2021

Riparian vegetation is important for stream functioning and as a major landscape feature. For many riparian plants, shallow groundwater is an important source of water, particularly in areas where rainfall is low, either annually or seasonally, and when extended dry conditions prevail for all or part of the year. The nature of tree water relationships is highly complex. Therefore, we used multiple lines of evidence to determine the water sources used by the dominant tree species Eucalyptus camaldulensis (river red gum), growing in riparian and floodplain areas with varying depth to groundwater and stream perenniality. Dendrometer bands were used to …

An Entropy-Histogram Approach For Image Similarity And Face Recognition, Mohammed Aljanabi, Zahir Hussain, Song F. Lu

Research outputs 2014 to 2021

Image similarity and image recognition are modern and rapidly growing technologies because of their wide use in the field of digital image processing. It is possible to recognize the face image of a specific person by finding the similarity between the images of the same person face and this is what we will address in detail in this paper. In this paper, we designed two new measures for image similarity and image recognition simultaneously. The proposed measures are based mainly on a combination of information theory and joint histogram. Information theory has a high capability to predict the relationship between …

Telomere Correlations During Early Life In A Long Lived Seabird, Jacob Schmidt

Biological Sciences

Telomere dynamics in blood cells have been linked to aging in a variety of organisms. However, whether blood telomeres correlated with telomeres in other parts of the body is not well known, especially during early life when telomere loss is expected to be most rapid. We investigated this question in embryonic and juvenile Franklin’s gulls (Leucophaeus pipixcan). We measured telomere lengths in blood, heart, liver and skeletal muscle tissues at the end of embryonic (n = 31) and post-natal development (n=20). In late-stage embryos, blood telomeres were significantly positively correlated with heart and skeletal muscle, but not liver telomeres. However, …

Personality And Behavioral Syndromes Of The Big Brown Bat, Eptesicus Fuscus, Amanda Marie Boyer

Biological Sciences

As the study of animal personality has significant expanded in the last decade, a growing amount of research has focused on the impacts of sociality and group dynamics on behavioral repeatability. The research presented here focused on examining personality in a captive colony of a common bat species, the big brown bat (Eptesicus fuscus). Chapter 1 focused on calculating repeatability along common personality axes, as well as examining relationships between these axes (behavioral syndromes). High repeatabilities were observed for two behavioral axes (exploration and activity) and a significant correlation was found between these axes, confirming a common behavioral syndrome. Chapter …

Regional Sea Level Rise Along The United States Coasts, Alessandra G. Burgos

OES Theses and Dissertations

Over the past several years, there has been several studies focused on reconstructing global mean sea level (GMSL) for the 20th century, along with projecting rates out into the future. Of greater importance for mitigation and adaptation plans, however, is the rate of local or regional sea level (RSL) rise. Ocean dynamics along with changes in Earth’s gravitational field can cause RSL to deviate from the change in GMSL. During the satellite altimeter era covering the past two decades, RSL trends can be four times the global average, with much of this spatial variation due to internal climate variability. Isolating …

Unobtrusive And Extensible Archival Replay Banners Using Custom Elements, Sawood Alam, Mat Kelly, Michele C. Weigle, Michael L. Nelson

Computer Science Faculty Publications

We compare and contrast three different ways to implement an archival replay banner. We propose an implementation that utilizes Custom Elements and adds some unique behaviors, not common in existing archival replay systems, to enhance the user experience. Our approach has a minimal user interface footprint and resource overhead while still providing rich interactivity and extended on-demand provenance information about the archived resources.

Quantification Of Twist From The Central Lines Of Β-Strands, Tunazzina Islam, Michael Poteat, Jing He

Computer Science Faculty Publications

Since the discovery of right-handed twist of a β-strand, many studies have been conducted to understand the twist. Given the atomic structure of a protein, twist angles have been defined using atomic positions of the backbone. However, limited study is available to characterize twist when the atomic positions are not available, but the central lines of β-strands are. Recent studies in cryoelectron microscopy show that it is possible to predict the central lines of β-strands from a medium-resolution density map. Accurate measurement of twist angles is important in identification of β-strands from such density maps. We propose an effective method …

Efficient Randomized Algorithms For The Fixed Precision Low Rank Matrix Approximation, Wenjian Yu, Yu Gu, Yaohang Li

Computer Science Faculty Publications

Randomized algorithms for low-rank matrix approximation are investigated, with the emphasis on the fixed-precision problem and computational efficiency for handling large matrices. The algorithms are based on the so-called QB factorization, where Q is an orthonormal matrix. First, a mechanism for calculating the approximation error in the Frobenius norm is proposed, which enables efficient adaptive rank determination for a large and/or sparse matrix. It can be combined with any QB-form factorization algorithm in which B's rows are incrementally generated. Based on the blocked randQB algorithm by Martinsson and Voronin, this results in an algorithm called randQB_EI. Then, we further revise …

Computational Investigation Of Energetic Materials: Influence Of Intramolecular And Intermolecular Interactions On Sensitivity, Ashley Lauren Shoaf

Chemistry & Biochemistry Theses & Dissertations

The development of novel high energy density materials (HEDMs) with superior energetic properties depends on characterizing how and why detonation occurs. Detonation is highly energetic and a nearly instantaneous process, making experimental studies challenging; thus, computational modeling through density functional theory (DFT) and molecular dynamics (MD) can be used to propose weakened, or activated, bonds that break to initiate explosive decomposition, termed trigger bonds. Bond activation is characterized by the Wiberg bond index (WBI), a measure of interatomic electron density. Trigger bonds in HEDMs are commonly found in explosophores, functional groups that contribute to energetic potential such as X-NO_{2 …}

In Praise Of The Catenary, Fred Behroozi

Faculty Work

When a chain hangs loosely from its end points, it takes the familiar form known as the catenary. Power lines, clothes lines, and chain links are familiar examples of the catenary in everyday life. Nevertheless, the subject is conspicuously absent from current introductory physics and calculus courses.1 Even in upper-level physics and math courses, the catenary equation is usually introduced as an example of hyperbolic functions or discussed as an application of the calculus of variations. We present a new derivation of the catenary equation that is suitable for introductory physics and mathematics courses.

Fish Consciousness, David Gamez

Animal Sentience

Woodruff makes two arguments to support his claim that ray-finned fish are conscious: (1) Fish neuroanatomy has similarities with the structures in the human brain that support consciousness. (2) The complexity and flexibility of fish behaviour suggest that they are conscious. This commentary will argue that neither the neuroanatomical nor the behavioural argument can provide conclusive evidence for consciousness in fish. We should suspend judgement until we have discovered mathematical theories of consciousness that can reliably map between states of consciousness and states of the physical world.

An Investigation Of Atomic Structures Derived From X-Ray Crystallography And Cryo-Electron Microscopy Using Distal Blocks Of Side-Chains, Lin Chen, Jing He, Salim Sazzed, Rayshawn Walker

Computer Science Faculty Publications

Cryo-electron microscopy (cryo-EM) is a structure determination method for large molecular complexes. As more and more atomic structures are determined using this technique, it is becoming possible to perform statistical characterization of side-chain conformations. Two data sets were involved to characterize block lengths for each of the 18 types of amino acids. One set contains 9131 structures resolved using X-ray crystallography from density maps with better than or equal to 1.5 Å resolutions, and the other contains 237 protein structures derived from cryo-EM density maps with 2-4 Å resolutions. The results show that the normalized probability density function of block …

The Photographic Other: Paradox In The Cathexis Of Longing, Alex Cilla Bradley

Theses: Doctorates and Masters

A photographic and written examination of paradox in relation to the photograph

This research aims to illuminate the relationship between paradox and photography, elaborated via Julia Kristeva’s notion of the abject. Paradox is considered in relation to photography in terms of repeated and unresolved debates about the status of the photograph as either an ‘index of reality’ (Bate, 2004, p. 1) or as a sign. The significance of this research lies in its re-motivation of abjection in terms of paradox, not in order to resolve such debates but, rather, to illuminate the importance of such unresolved contradictions in terms of …

Within-Fire Patchiness Associated With Prescribed Burning In The Northern Jarrah Forests Of Western Australia, Zigourney Nielsen

Theses: Doctorates and Masters

There is growing understanding of the importance of landscape mosaics and heterogeneity for biodiversity outcomes in Western Australia. However, there is limited information on the patchiness (spatial configuration of unburnt and burnt patches which occur at a range of spatial scales) within the perimeter of a single prescribed burn. Of particular concern is the idea that prescribed burning operations, carried out under very restricted weather and environmental conditions, can lead to structural and floristic homogenization of the area within a burn perimeter. This may be evident as reduced post-fire vegetation patchiness. Western Australian Jarrah (Eucalyptus marginata) forests are managed to …

Theses: Doctorates and Masters

Changes to education policies and the creation of new curricula in Western Australia (WA), such as the new WA Humanities and Social Sciences (HASS) Curriculum in 2017, may place external pressure on teachers as they transition from existing to new curricula. The aim of this interpretivist study was to investigate the transition to the new WA HASS Curriculum in 2017. The experiences and perspectives of the school leaders and teachers in Pre-primary, Year One and Year Two (PP to Y2) in two Perth metropolitan independent schools was explored. The preparation undertaken by the early childhood teachers and leaders, and the …

A Study On The Impact Of A Music Looping Technology Intervention Upon Pre-Service Generalist Teachers’ Self-Efficacy To Teach Music In Primary Schools, John Nathan Heyworth

Theses: Doctorates and Masters

In Australia, in the current climate of economic rationalism in which there has been an increasing emphasis on literacy and numeracy, funding for specialised subjects like music has been reducing. As a result, generalist classroom teachers are being given more responsibility for delivering effective music education in primary schools. However, the time dedicated to training pre-service teachers in music education in tertiary institutions has diminished. Further, time constraints involved in building pre-service knowledge and skills in teaching music may impact many pre-service teachers’ beliefs about their ability to teach music.

Within these constraints, digital technology may provide a key to …

The rapid growth in global mobile phone users has resulted in an ever-increasing demand for bandwidth and enhanced quality-of-service (QoS). Several consortia comprising major international mobile operators, infrastructure manufacturers, and academic institutions are working to develop the next generation wireless communication systems fifth generation (5G) - to support high data rates and increased QoS. 5G systems are also expected to represent a greener alternative for communication systems, which is important because power consumption from the information and communication technology (ICT) sector is forecast to increase significantly by 2030. The deployment of ultra-dense heterogeneous small cell networks (SCNs) is expected to …

The Rhythmic, Harmonic And Phrasing Language Of Lennie Tristano: Analysis And Strategies For Incorporation In Modern Jazz Improvisation, Austin Salisbury

Theses : Honours

Pianist Lennie Tristano is regarded as one of the most original voices in jazz history. His uncompromising adherence to artistic ideals led to both great innovation and obscurity, limiting his impact on future generations of musicians. Until recently, his music has been largely overlooked by musicians and academics alike. Coinciding with a revival in interest in Tristano and his music by modern jazz musicians, this dissertation seeks to investigate the transferability of several aspects of Tristano’s rhythmic, harmonic and phrasing vocabulary to modern jazz improvisation. Building upon existing literature concerning his pedagogy and musical analysis, this research emphasises Tristano’s relevance …

A Survey To Investigate The Participation Of Female Jazz-Trained Instrumentalists At Waapa And In Perth’S Professional Music Scene, Talya Valenti

Theses : Honours

Traditionally, men have dominated jazz music in terms of participation and professional acknowledgement, but even in present times, female instrumentalists remain under-represented in jazz performance and education. Various studies such as Kathleen M. McKeage’s Gender and Participation in Undergraduate Jazz Ensembles: A National Survey and Erin L. Wehr’s Understanding the Experiences of Women in Jazz: A Suggested Model, have produced statistics that illustrate the low participation of female instrumentalists in jazz, and have also provided social-psychological theories to explain why these patterns continue to prevail.

As a working jazz-trained female instrumentalist myself, I have noticed the under-representation of female jazz …
