- Description: Classification of objects based on inherent properties is a general problem area encountered in diverse fields of knowledge. In terms of text classification, the problem presented in this work is based on two particular criteria for documents as given below: • Informativeness of feature sets - A feature set would comprise of words in a document. Presence of words that can be used to characterize a document in a corpus (database) is the informativeness of a feature set. • Multilabelness - documents can have content dealing with diverse topics These criteria are not localized to documents only, but can be generalized to other areas as well with little adaptation. In this thesis, the classification problem that is being investigated involve datasets containing the prescence of smaller number of features associated with a larger number of classes. The acronym SFML (Shorter Featured & Multi-Labeled) has been used to denote these types of datasets. Further, SFML type datasets can be encountered in various walks of life, like Medicine, SMS Services, Text Classification to name a few. In this thesis, the performance of various existing classification algorithms were tested on SFML datasets and their results compared. Further, a new classification algorithm based on optimization is also proposed for these types of datasets. Applications to the Adverse Drug Reaction problem and phishing profiling problem have been considered here. Classification results show that the proposed algorithm performs better than existing classification algorithms as the number of features tend to decrease.

The lived experience of security and contentment for latency aged children in shared care, post-separation : a descriptive phenomenological enquiry
- Authors: Sadowski, Christina
- Date: 2012
- Type: Text , Thesis , PhD
- Full Text: false
- Description: "As a result of complex social, economic and legislative factors, the number of children in shared time arrangements (in which children spend equal, or near-equal time, with both parents post-separation) has risen steadily and incrementally in Australia and internationally. Despite the increasing numbers of children in this arrangement, conceptualisations of and discussions about shared care remain largely devoid of children's perspectives about their experiences. As a result, little is known about how children experience this way of living. This study used a descriptive phenomenological approach to explore latency aged (aged 8-12) children's lived experience of security and contentment, and their absence, in a shared care time arrangement." "Interviews were conducted with sixteen children across a diversity of living arrangements (levels of parental cooperation and conflict; self-selected and Court-ordered; day-to-day patterns) who had current or recent experience living in shared care. From this pool of interviews, the eight richest and detailed protocols were selected for descriptive phenomenological analysis. Through a process of detailed analytic exploration of these eight individual descriptions of phenomena under investigation (security and contentment in shared care; the absence of security and contentment in shared care), the core constituents of each phenomenon were discerned. From these, General Structures representing the essence, or the invariants common to all experiences under investigation, were identified. This thesis introduces a child-generated phenomenology of security and contentment, and their absence, in shared care. This phenomenology is based on the careful analysis of children's pre-reflective narrative descriptions, describing core aspects of this arrangement that contribute to their felt security and contentment, and core aspects that compromise it. Ultimately, this thesis presents the child's lived experience of feeling securely shared by parents in the context of a shared time living arrangement. "

Barley non-starch polysaccharide content and its relationship with kernel hardness and water uptake
- Authors: Gamlath, Jayantha
- Date: 2009
- Type: Text , Thesis , PhD
- Full Text: false
- Description: Harder kernels in barley are thought to be a factor affecting the modification of the endosperm during malting by restricting water and enzyme movement within the endosperm. The traditional method used in the malting industry to determine barley endosperm vitreousness is by visual assessment. Since this method is subjective, laborious and requires training, an alternative method is needed. Similarly, the causes and factors influencing kernel hardness are uncertain. The prime objectives of this study were: to identify an appropriate method to quantify kernel hardness; investigate the relationship between kernel hardness and endosperm composition; and to investigate the relationship between barley variety and environmental influences on endosperm composition in relation to the kernel hardness of malting barley.

Very low frequency - Magnetic spatial position detection range and map
- Authors: Poplawski, Jaroslaw
- Date: 2008
- Type: Text , Thesis , PhD
- Full Text: false
- Description: Automated positioning systems designed to measure three-dimensional locations of objects are of paramount importance to flexible manufacturing applications. These systems should perform in an industrial environment, withstanding obstacles of solid objects and must be immune from external influences including changes in atmospheric conditions and surrounding noise. Automated positioning systems should also be free of mechanical contact and able to perform without having to establish a line-of-sight with the measured object. In this thesis, a novel design is proposed for the spatial measurement of the six degrees of freedom industrial robots and autonomous vehicles. Not only does the proposed system comply with the above characteristics, but it is also capable of achieving better resolutions than CCD cameras, easier to implement, safer than laser devices and more accurate than ultrasound systems.[...]

Women in 'Ballarat" 1851-1871: a case study in agency
- Authors: Wickham, Dorothy
- Date: 2008
- Type: Text , Thesis , PhD
- Full Text: false
- Description: This thesis argues that European women exercised agency in mid nineteenth century Ballarat. It develops an understanding of women as active agents who engaged with, and negotiated, relationships of power. It highlights the fluidity in gendered roles, the blurred lines between the public and private domains, and the complexity of colonial life and relationships. This social and feminist history situates women within the system of patriarchal power which systematically and overtly benefited men. It reveals the complex operation of patriarchal power in which women accepted, challenged, and resisted social values and constructs. Such a consideration of the structure of power dislodges the notion of women as oppressed bodies who passively accepted universal and monolithic patriarchal values, and instead highlights diversity within gendered power structures. Drawing on public documentation, narrative, biographical, and statistical information from a diverse, extensive, and comprehensive range of archival sources, this thesis utilises a form of microhistorical methodology to detail and analyse the ways in which colonial women helped to shape society. It then draws a broader interpretation from such analysis to locate this thesis among other feminist and goldfields discourses. Through the central themes of health, birth, death, marnage, family, law, religion, temperance, philanthropy, work and public protests, this study_ identifies strands of agency exercised by Ballarat' s colonial women during the city's metamorphosis from the heady early days after the official discovery of payable gold in 1851 and the subsequent expansion of colonial settlement, to the consolidation of the City of Ballarat in 1871. Women predominantly acted as domesticating, nurturing and civilising agents, their actions deriving legitimacy from patriarchal values and endorsed by men. Women also contested, challenged, negotiated, manipulated, resisted and rejected socially accepted values, while playing out their lives within the colonial society in which they lived.

Secret suburbia : An anthology of concepts relating to house and home

- Full Text: false
- Description: The aim of this research project has been to merge components of ideas relating to House and Home that have been formed by the inherently sensitive autobiographical nature of my own experience whilst growing up in a suburban environment. Naturally, these symbols or metaphors of the mundane reveal much more than what superficial impressions allow. They invite the viewer into an inner world of dream /memory and hypothesis that hopefully invokes within the viewer a desire to reach beyond their own perceptions of the everyday, and to re-examine the source of their own identity, thereby bringing some new emphasis to their own significant journey.
