Gait Entrainment In Coupled Oscillator Systems: Clarifying The Role Of Energy Optimization In Human Walking, Ryan T. Schroeder

Theses: Doctorates and Masters

Empirical evidence suggests that parameters of human gait (e.g. step frequency, step length) tend to minimize energy expenditure. However, it is unclear if individuals can adapt to dynamic environments in real time, i.e. continuously optimize energy expenditure, and to what extent. Two coupled oscillator systems were used to test the learned interactions of individuals within dynamic environments: (1) experienced farmworkers carrying oscillating loads on a flexible bamboo pole and (2) individuals walking on a treadmill while strapped to a mechatronics oscillator system providing periodic forces to the body. Reductionist trajectory optimization models predicted energy-minimizing gait interactions within the coupled oscillator …

Improving Sprint Performance In Road Cycling: The Forward Standing Sprint Position, Paul Franciscus Johannes Merkes

Theses: Doctorates and Masters

The majority of road cycling races finish with a sprint and as such sprints are a key determinant of success. Surprisingly, the scientific literature on this specific topic is scarce, with limited to few studies describing the characteristics of road cycling sprinters and the demands of road sprinting. Cyclists’ sprinting velocity, which is mostly influenced by power output and aerodynamic drag (CdA) is critical to performance outcomes. However, to date, there is very limited research specifically examining how to maximise road sprint velocity. Thus, the overall objective of the four studies outlined in this thesis was to manipulate CdA, physiology, …

Determining Ground-Level Composition And Concentration Of Particulate Matter Across Regional Areas Using The Himawari-8 Satellite, Miles Sowden

Theses: Doctorates and Masters

Speciated ground-level aerosol concentrations are required to understand and mitigate health impacts from dust storms, wildfires and other aerosol emissions. Globally, surface monitoring is limited due to cost and infrastructure demands. While remote sensing can help estimate respirable (i.e. ground level) concentrations, current observations are restricted by inadequate spatiotemporal resolution, uncertainty in aerosol type, particle size, and vertical profile. One key issue with current remote sensing datasets is that they are derived from reflectances observed by polar orbiting imagers, which means that aerosol is only derived during the daytime, and only once or twice per day.

Sub-hourly, infrared (IR), geostationary …

The Integration Of Pumped Hydro Storage Systems Into Pv Microgrids In Rural Areas, Navid Mousavi

Theses: Doctorates and Masters

Photovoltaic (PV) systems are popular in rural areas because they provide low cost and clean electricity for homes and irrigation systems. The primary challenge of PV systems is their intermittent nature. The typical solution is storing energy in batteries; however, they are expensive and possess a short lifespan. This research proposes a new type of pumped hydro storage (PHS) which can be implemented as an alternative to batteries. The components of the system are modelled to consider losses of the system accurately. The mathematic model developed in this project assists the management system to make more efficient decisions. The proposed …

Educational And Psychosocial Development Of Adolescents In Specialist Sport Programs In Low Ses Areas Of Perth, Western Australia, Eibhlish Máire Bridget O'Hara

Theses: Doctorates and Masters

Adolescents from low socio–economic (SES) backgrounds are more vulnerable, experience more physical and mental health problems, and often do not have as many positive educational outcomes as adolescents from higher SES backgrounds (Totten, 2007). Most research examining youth recreational activities, such as sport programs, demonstrate the positive influence they can have, especially for adolescents living in low SES neighbourhoods (National Research Council and Institute of Medicine, 2002). However, adolescents living in low SES neighbourhoods often have limited access to such programs (Leventhal, Dupéré, Brooks-Gunn, 2009). As such, it is important to find alternate ways for adolescents living in low SES …

Wildfire Suppression – An International Analysis Of Operations, Strategy And Firefighter Safety, Greg Peter Penney

Theses: Doctorates and Masters

Wildfire suppression remains an inherently dangerous yet increasingly frequent task for fire services throughout Australia and the world. Each year firefighters from career and volunteer agencies respond to wildfires that impact the urban interface. When such an event occurs during a period of intense fire behaviour the conditions are often incompatible with life for persons either caught in the open or those seeking refuge in a vehicle. In order to improve firefighter safety and operational effectiveness at the rural urban interface (RUI) during landscape scale wildfires, this dissertation serves to examine critical components of wildfire response, most notably wildfire suppression …

Local Binary Pattern Based Algorithms For The Discrimination And Detection Of Crops And Weeds With Similar Morphologies, Vi Nguyen Thanh Le

Theses: Doctorates and Masters

In cultivated agricultural fields, weeds are unwanted species that compete with the crop plants for nutrients, water, sunlight and soil, thus constraining their growth. Applying new real-time weed detection and spraying technologies to agriculture would enhance current farming practices, leading to higher crop yields and lower production costs. Various weed detection methods have been developed for Site-Specific Weed Management (SSWM) aimed at maximising the crop yield through efficient control of weeds. Blanket application of herbicide chemicals is currently the most popular weed eradication practice in weed management and weed invasion. However, the excessive use of herbicides has a detrimental impact …

Leveraging Genome-Enabled Growth Models To Study Shoot Growth Responses To Water Deficit In Rice, Malachy T. Campbell, Alexandre Grondin, Harkamal Walia, Gota Morota

Department of Agronomy and Horticulture: Faculty Publications

lucidating genotype-by-environment interactions and partitioning its contribution to phenotypic variation remains a challenge for plant scientists. We propose a framework that utilizes genome-wide markers to model genotype-specific shoot growth trajectories as a function of time and soil water availability. A rice diversity panel was phenotyped daily for 21 d using an automated, high-throughput image-based, phenotyping platform that enabled estimation of daily shoot biomass and soil water content. Using these data, we modeled shoot growth as a function of time and soil water content, and were able to determine the time point where an inflection in the growth trajectory occurred. We …

Governing The Patent Commons, Dirk Auer, Julian Morris

Cardozo Arts & Entertainment Law Journal

Thousands of patents underpin the technologies that power the digital economy. Coordination among firms developing and implementing these novel technologies has notably been facilitated in large part by Standards Developing Organizations (SDOs). Despite the evident benefits of standardization in general and SDOs in particular, certain aspects of these processes have come under severe scrutiny from scholars, antitrust authorities, and courts. These critics argue that the standardization space suffers from two crippling market failures, namely "patent holdup" and "royalty stacking." They thus conclude that opportunistic firms will squeeze their rivals 'profits, harming consumers and stifling innovation in the process. However, recent …
