Biological Maturity And The Anthropometric, Physical And Technical Assessment Of Talent Identified U16 Australian Footballers, A Cripps, C Joyce, C Woods, L Hopper

Health Sciences Papers and Journal Articles

This study compared biological maturation, anthropometric, physical and technical skill measures between talent and non-talent identified junior Australian footballers. Players were recruited from the under 16 Western Australian Football League and classified as talent (state representation; n = 25, 15.7 ± 0.3 y) or non-talent identified (non-state representation; n = 25, 15.6 ± 0.4 y). Players completed a battery of anthropometric, physical and technical skill assessments. Maturity was estimated using years from peak height velocity calculations. Binary logistic regression was used to identify the variables demonstrating the strongest association with the main effect of ‘status’. A receiver operating characteristic curve …

The Most Important "Factor" In Producing Clubhead Speed In Golf, C Joyce

Health Sciences Papers and Journal Articles

Substantial experiential research into x-factor, and to a lesser extent crunch-factor has been undertaken with the aim of increasing clubhead speed. However, a direct comparison of the golf swing kinematics associated with each ‘factor’ has not, and possible differences when using a driver compared to an iron. Fifteen low handicap male golfers who displayed a modern swing had their golf swing kinematic data measured when hitting their own driver and five-iron, using a 10-camera motion analysis system operating at 250 Hz. Clubhead speed was collected using a validated launch monitor. No between-club differences in x-factor and crunch-factor existed. Correlation analyses …

Modelling And Simulation Of Grid Connected Lithium-Ion Battery Using Homer, Shantu Ghose, Adel El-Shahat

Electrical & Computer Engineering: Faculty Publications

In order to improve battery technology understanding the capacity fading method in batteries is very important. Battery models can be used to predict their behavior under various operating conditions. Here we proposed a simple dynamic model of lithium-ion battery with MATLAB/Simulink to observe the output characteristics of this energy storage device. Dynamic simulations are carried out, including the observation of the changes in battery terminal output voltage under different discharging/charging, temperature and cycling conditions. The simulation studies are presented for proving that the model is useful. At the end we will use this energy storage device to interconnect with HOMER. …

Bayesian Cox Proportional Hazards Model In Survival Analysis Of Hace1 Gene With Age At Onset Of Alzheimer’S Disease, Ke-Sheng Wang, Ying Liu, Shaoqing Gong, Chun Xu, Xin Xie, Liang Wang, Xingguang Luo

Health & Biomedical Sciences Faculty Publications

Alzheimer’s Disease (AD), the most common form of dementia, is a chronic neurodegenerative disease. The HECT domain and ankyrin repeat containing E3 ubiquitin protein ligase 1 (HACE1) gene is expressed in human brain and may play a role in the pathogenesis of neurodegenerative disorders. Till now, no previous study has reported the association of the HACE1 gene with the risk and Age at Onset (AAO) of AD; while few studies have checked the proportional hazards assumption in the survival analysis of AAO of AD using Cox proportional hazards model. In this study, we examined the associations of 14 Single Nucleotide …

The Poverty Simulation: Increasing Teacher Sensitivity For Students Living In Poverty, Aviva Goelman Rice, Linda Ann Mccall, Jacquelyn E. Ogden

National Youth Advocacy & Resilience Journal

Studies of children growing up in poverty describe increasingly devastating effects on many areas of development (e.g., cognitive, linguistic, socio-emotional, affective, psychomotor). Teachers need to be aware of these findings; they also need to develop empathy for their students living in poverty. One way to do this is to experience a poverty simulation wherein participants (i.e., teachers) learn what it is like to “walk in their students’ shoes.” This report describes the history of a poverty simulation in southeast Georgia. Analysis of quantitative data, collected via surveys administered before and after recent poverty simulations, revealed the following findings: increased teacher …

Taxonomy, Physiology And Biochemistry Of The Sulfur Bacteria, Lee Hutt

School of Biological and Marine Sciences Theses

Inorganic sulfur-oxidising Bacteria are present throughout the Proteobacteria and inhabit all environments of Earth. Despite these facts they are still poorly understood in terms of taxonomy, physiology, biochemistry and genetics. Using phylogenetic and chemotaxonomic analysis two species that were erroneously classified as Thiobacillus trautweinii spp. in 1921 and 1934 are in fact novel chemolithoheterotrophic species for which the names Pseudomonas trautweiniana sp. nov. and Achromobacter starkeyanus sp. nov. are proposed, respectively. These species were found to oxidise thiosulfate in a “fortuitous” manor when grown in continuous culture and increases in maximum theoretical growth yield (YMAX) and maximum specific growth rate …

Haplós: Towards Technologies For And Applications Of Somaesthetics, Diego Silang Maranan

School of Art, Design and Architecture Theses

How can vibrotactile stimuli be used to create a technology-mediated somatic learning experience? This question motivates this practice-based research, which explores how the Feldenkrais Method and cognate neuroscience research can be applied to technology design. Supported by somaesthetic philosophy, soma-based design theories, and a critical acknowledgement of the socially-inflected body, the research develops a systematic method grounded in first- and third-person accounts of embodied experience to inform the creation and evaluation of design of Haplós, a wearable, user-customisable, remote-controlled technology that plays methodically composed vibrotactile patterns on the skin in order to facilitate body awareness—the major outcome of this research …

The aim of the study is to implement a functional mechanism to evaluate and analyse changes in the Lagos Lagoon and its ecosystem, with the objectives: (i) to investigate the extent and impact of urban expansion on the Lagoon coastline and its ecosystem; (ii) to quantify changes in the spatial extent of mangroves by use of satellite images from 1984 to 2016; (iii) to investigate the spatial dynamics of the …

Modulation Of Innate Immune Cells By The Nad+ Pathway, Abbas Jawad Al-Shabany

School of Biological and Marine Sciences Theses

NAD+ has previously been shown to regulate TNF-α synthesis and TNF-α has been shown to regulate NAD+ homeostasis, thus providing a link between a pro-inflammatory response and redox status. Despite the well-established link between TNF-α and NAD+, the mechanism as to how NAD+ modulates TNF-α release is not fully understood. To achieve this, this link was investigated using THP-1 cell line-derived M1-like (pro-inflammatory) and M2-like (anti-inflammatory) macrophages using PMA and vitamin D3, respectively. NAD+ levels differed markedly between M1-like and M2-like macrophages, with M1-like having much higher basal levels. LPS increases NAD+ levels and TNF-α secretion in M1-like but not …

The Biological And Ecological Impacts Of Hypoxia On Coastal Benthic Communities, Ruth Naomi Calder-Potts

School of Biological and Marine Sciences Theses

Traditionally, hypoxia has been defined as the situation where DO levels have fallen below 2.0 mg O2 L-1, but increasing evidence suggests that this low level of DO is inadequate to describe the onset of hypoxia impacts for many organisms. Consequently, there is a need for a greater understanding of how ‘moderate’ alterations in DO levels will affect ecosystem processes and functionality, specifically through behavioural and physiological alterations at the organism and community level. This thesis reports on mesocosm experiments which were conducted to examine the effects of moderate (> 3.0 mg O2 L-1) hypoxia on firstly, a key ecosystem …

Spatial And Temporal Variability Of Sandy Beach Sediment Grain Size And Sorting, Sam Prodger

School of Biological and Marine Sciences Theses

Beach grain size plays a major role in controlling beach slope and sediment transport rates and is a crucial criterion in selecting the appropriate fill material for beach nourishment. Yet, little is known about how and why beach grain size (and sorting) varies both spatially and temporally on high-energy sandy beaches. Therefore, in this PhD research project, the presence, magnitude and predictability of any spatio-temporal sediment variability was investigated on a number of contrasting high-energy (average significant wave height = 0.8 to 3.5 m), predominantly macrotidal (MSR = 3.1 – 6.2 m), sandy (0.26 – 0.64 mm) beach sites around …

The Microbiological Safety Of Fresh Produce In Lebanon- A Holistic “Farm-To-Fork Chain” Approach To Evaluate Food Safety, Compliance Levels And Underlying Risk Factors, Dima Faour-Klingbeil

School of Biological and Marine Sciences Theses

The consumption of unsafe fresh vegetables has been linked to an increasing number of outbreaks of human infections. In Lebanon, although raw vegetables are major constituents of the national cuisine, studies on the safety of fresh produce are scant. This research employed a holistic approach to identify the different stages of the food chain that contribute to the microbiological risks on fresh produce and the spreading of hazards. A thorough analysis of the institutional and regulatory framework and the socio-political environment showed that the safety of local fresh produce in Lebanon is at risk due to largely unregulated practices and …

Field Observations Of Infragravity Wave Response To Variable Sea-Swell Wave Forcing, Kris William Inch

School of Biological and Marine Sciences Theses

Infragravity waves are low frequency (0.005-0.04 Hz) waves that can dominate the spectrum of water motions and sediment transport processes within the inner surf zone. Despite the established importance of infragravity waves in shaping our coasts and numerous studies dating back to the 1950s, several aspects of infragravity wave analysis, generation and dissipation remain poorly understood. As much of the recent infragravity research has focussed on fetch-limited coasts, less is known about the climatology of these waves on energetic coastlines subject to both swell and fetch-limited waves. It has been postulated that bed friction only plays a significant role in …

Factors Affecting Participation In Group Agri-Environment Schemes: A Case Study Of The Dartmoor Commons, Ann Willcocks

On The Relationship Between Sampling Rate And Hidden Markov Models Accuracy In Non-Intrusive Load Monitoring, Steven Lynch, Luca Longo

Conference papers

Providing domestic energy consumers with a detailed breakdown of their electricity consumption, at the appliance level, empowers the consumer to better manage that consumption and reduce their over- all electricity demand. Non-Intrusive Load Monitoring (NILM) is one method of achieving this breakdown and makes use of one sensor which measures overall combined electricity usage. As all appliances are measured in combination in NILM this consumption must be disaggregated to extract appliance level consumption. Machine learning techniques can be adopted to perform this disaggregation with various levels of accuracy, with Hidden Markov Model (HMM) derivatives ordering among the most accurate results. …

Dynamic Behavior Analysis Of Android Applications For Malware Detection, Latika Singh, Markus Hofmann

Conference papers

Android is most popular operating system for smartphones and small devices with 86.6% market share (Chau 2016). Its open source nature makes it more prone to attacks creating a need for malware analysis. Main approaches for detecting malware intents of mobile applications are based on either static analysis or dynamic analysis. In static analysis, apps are inspected for suspicious patterns of code to identify malicious segments. However, several obfuscation techniques are available to provide a guard against such analysis. The dynamic analysis on the other hand is a behavior-based detection method that involves investigating the run-time behavior of the suspicious …

Measuring Presence: Hypothetical Quantitative Framework, Krzysztof Szczurowski, Matt Smith

Conference papers

Virtual Reality Head - Mounted Display (HMD) manufacturers claim that consumer electronics can finally deliver a high degree of presence in virtual and remote environments. Certainly, current consumer-grade HMD systems offer rich and coherent mediated experiences of such environments. However, the very concept of presence is still a subject of debate, and researchers' investigation of the phenomenon of `presence' is based primarily on qualitative (i.e. questionnaire-based) assessments. Some researchers attempted to develop real-time, quantitative methods to facilitate more objective investigation of presence in mediated environments. Most such methodologies are derived from attempts to correlate presence with cardiovascular and electrodermal activity …

Design And Evaluation Of Ballast Water Management Systems Using Modified And Hybridised Axiomatic Design Principles, Lawrence Kuroshi

World Maritime University Ph.D. Dissertations

There are two major motivations to this research. The first is based on the concerns raised at the International Maritime Organisation (IMO) MEPC 67 and 68 meetings regarding the capacity of some type-approved Ballast Water Management (BWM) Systems to meet the performance standard (D-2) of the BWM Convention at-all-times and in all conditions. The second is based on the reluctance expressed by some ship- owners to install the system onboard their ships as a Lloyd's list survey suggested.

In this work, an attempt was made to address these issues and concerns using a set of criteria stipulated in Regulation D-5.2 …

A Holistic Risk-Oriented Framework For Port Infrastructure Adaption To Climate Change, Kana Nkasanga Patrick Mutumbo

World Maritime University Ph.D. Dissertations

This research is the first attempt in developing a broad-based qualitative tool for assessing climate risk in ports and building resilience. In order to demonstrate the applicability of the conceptual tool, the new Durban Dig-Out Port (DDOP) under development in the City of Durban (South Africa) is used for case study. Central to this research is the building of widespread industry recognition of the need to factor climate change into decision making at early stages of port development.

The recent significant shift toward supply chain management and customer orientation practices calls for the need to assess the effectiveness of port …

Comparing Region Level Testing Methods For Differential Dna Methylation Analysis, Arnold Albert Harder

Masters Theses

”Finding possible connections and solutions to help fight progression of diseases is a major area of research. Genomics is a primary path of research in disease research. Through the DNA sequence, possible connections to diseases have been found. However, most methods for fixing issues within a DNA sequence are still out of reach. One potential path is to investigate epigenetic modifications, such as DNA methylation. DNA methylation occurs when a methyl group attached to cytosines on the DNA sequence. Statistical methods can be used to identify sites or regions of significant differences in methylation levels between groups ( e. g. …
