Underwater kicking following the freestyle tumble-turnClothier, Peter . University of Ballarat. January 2004 (has links)
Swim turns are a component of competitive swimming where considerable advantage can be gained or lost. This thesis investigates underwater dolphin and flutter kicking techniques and their application to exits following the turn in freestyle swimming. Five separate investigations were conducted to examine the kinetics and kinematics of each underwater kicking technique and are presented in expanded journal manuscript form. Studies one, two and three involved the comparison of freestyle turns when using flutter and dolphin kicking wall exit techniques. The results obtained indicated that freestyle turns using flutter kicking were faster than dolphin kicking in age-group swimmers. For this group, significant and equal improvements were made to flutter and dolphin kick turn performances following six weeks of dolphin kick and dolphin kick turn training. However, no difference in turn times were observed between kicking conditions by older and more highly skilled swimmers. Study four involved a kinematical comparison of maximal underwater free-swimming dolphin and flutter kicking. Results showed dolphin kick to be a superior underwater free-swimming technique. Greater foot width, increased ankle range of movement and greater vertical displacement of the ankle and foot during kicking were shown to be highly predictive of faster underwater dolphin kicking. Investigation five compared the drag forces and kinematics between the dolphin and flutter kicking techniques while subjects were towed at velocities representing those experienced following wall turn push-off. Results favour the dolphin kick as a superior underwater technique at these higher velocities. Increased underwater dolphin kicking efficiency, as measured by decreased net towing force, was found to be associated with larger kick amplitude – rate ratios, and higher kick amplitude – streamline length ratios. / Doctor of Philosophy

Incidence and aetiological factors in the development of medial tibial stress syndromeDiacogiorgis, Dimitri . University of Ballarat. January 2005 (has links)
The aim of this 13 week prospective study was to investigate whether differences in hip, knee, ankle, subtalar, or first metatarsophalangeal joint (MPJ) range of motion and physical activity levels increase a person's likelihood of developing medial tibial stress syndrome (MTSS)." --p.2. / Master of Applied Science

Changing rural general practitioner practice : evaluating health assessment uptakeMcGrath, Alicia . University of Ballarat. January 2003 (has links)
The Enhanced Primary Care Package aimed to improve health and quality of life through enhancing primary health care for those over 75 years, Aboriginal and Torres Strait Islanders over 55 years and those with chronic conditions and multidisciplinary needs. A multi-level approach was implemented to promote the package. West Vic Division of General Practice conducted the General Practice Education Support and Community Linkages implementation program for the package in Western Victoria and focused on health assessments for those over 75 years. This research investigated what factors affected change in rural general practitioner practice through surveying general practitioners and collecting Health Insurance Commission data prior to and following the program. Patients were also interviewed to determine acceptance of health assessments and nurse involvement. The program increased awareness, but had little effect on increasing uptake, as only 53% of general practitioners began undertaking health assessments. However the general practitioners indicated an increased frequency of health assessment prescription. Health Insurance Commission data suggested an immediate increase in the use of the assessments, however the rate fluctuated and then declined. Lack of sustained uptake of the program was not associated with remuneration, as 77% of general practitioners did not regard finance as a barrier. Respondents’ major barrier was time (40% pre-education, 73% post-education). This data reflected a rural environment where general practitioners face competing priorities, time constraints, workforce shortage and long consultation lists. A notable change did however occur from practice nurse employment as the involvement of a practice nurse generally resulted in patient satisfaction with the assessment. It was apparent that a complex multifaceted and longer-term view is needed to address factors which limit rural general practitioners’ ability to change. This needs to be addressed at the Commonwealth level and not in isolation in order to produce an integrated framework to enhance and promote, rather than demand change. / Master of Applied Science

Optimal number and placement of network infrastructure in wireless networksKouhbor, Shahnaz . University of Ballarat. January 2007 (has links)
Wireless Local Area Networks (WLANs) have become a major success in telecommunications during the last few years, due to advantages such as mobility, flexibility, and easier maintenance. A device called an access point (AP) acts as a base station in WLAN for connecting a group of users to the network via radio signal. During the planning of such a network an important problem is to determine the optimal number of these devices and their placement/distribution so that coverage, capacity, and physical security are maximised at minimum cost. In this thesis we are using continuous optimisation techniques to optimise the number of APs and their distribution while cost of deployment is reduced and physical security of the network is enhanced. To find the number and placement of APs, we developed a multi-objective functions model based on path losses and power for free space environments. The two functions in the models are combined by using a balancing parameter. Since it is recognised that some of the objectives can be handled one at a time, in another approach, we followed a step-by-step procedure. We start with a novel optimisation model based on path losses for indoor environments including obstacles. Cost of deployment is saved by finding the minimum number of APs ensuring that the path loss at each test point/receiver is below the given maximum path loss. Next, the physical security of the network is enhanced by placing the APs far from places accessible to unauthorised users to reduce the risk of intrusion into the network. This is achieved in the framework of the model by introducing potential unauthorised users in unauthorised areas for whom coverage is minimised. Due to the presence of obstacles in indoor buildings, the path loss function is discontinuous. Therefore, the objective functions are very complicated and most of the existing optimisation algorithms cannot be applied to solve the problem. We use a global optimisation algorithm that is not used by other researchers to solve the same problem. To validate the accuracy of the optimisation model and performance of the numerical methods, we run tests on several indoor buildings and use wide range of WLAN parameters. The results demonstrate the quality of our model and algorithm. Based on the proposed model and algorithm, we developed a software to assist the network designers in planning wireless LANs. / Doctor of Philosophy

A locale of the cosmos : an epic of the Wimmera : exegesis and textRieth, Homer Manfred . University of Ballarat. January 2006 (has links)
"This project has, for its central component, an epic poem, 'A locale of the cosmos'. The accompanying exegesis examines epic as an ancient, but continually evolving form. It argues that, as a contemporary example of the genre and, as a sustained poetic rumination on landscape and memory, 'A locale of the cosmos' represents a significant development within the modern tradition of autobiographical epic. In broader terms, 'A locale of the cosmos' privileges the landscape and history of a region of Australia, the Wimmera region of north-western Victoria and, in doing so, explores the cumulative effects of the physical environment as a site for sustained poetic treatment. The poem is, therefore, an epic of both historical narrative and philosophical reflection, giving meaning to and interpreting ideas of space, place and locale. "Furthermore, it explores, in particular, the psychological and spiritual effects of vast horizontal distances, created by a landscape in which endless plains and immense horizons form an analogue of the wider cosmos. The poem's themes, therefore, bear not only on the prominences of the visible locale, but also explore the salients of an interior world, a landscape of the mind to which the poetry gives shape and meaning." / Doctor of Philosophy

An Investigation into the experiences of occupational stress of graduate nurses in Hong KongLee, Irene . University of Ballarat. January 2006 (has links)
"The major criticism by hospital trained clinical nurses is that university graduates are perceived as not being competent practioners as a result of limited time spent in clinical areas. This lack of clinical experience is thought to contribute to new graduates' sense of occupational stress."--leaf xii. / Doctor of Philosophy

Space : contemplating the voidsZuccolo, Michelle . University of Ballarat. January 2006 (has links)
This research project into the manipulation of spatial concepts by artists on the two-dimensional surface plane, has involved a selected study into cultural and aesthetic evolution from early civilization through to the present era. I have cast a line of inquiry into eastern, western and primitive art practices, observing the journey of chance accelerated by developments in technology. Traditionally artists utilized modes of spatial convention and techniques according to the specific cultural traditions of the time and place of their production. By contrast, contemporary artists know no such boundaries, and are able to select from a range of spatial options relevant both to current forms of expression and to a personal visual language. My own art practice has been enriched and extended, increasing my ability to challenge the notion of still life composition by reversing the traditional hierarchy of form and space through the application of a series of experiments brought about by extensive research into this spatial evolution. The research project has further assisted this development in my art practice by engaging me in a new level of understanding of the topic, informing my perceptions and increasing my ability to translate a combination of forms in space with heightened emotion and personal meaning. / Master of Arts (Visual Arts)
