Small Unmanned Aerial Vehicles (UAVs) have seen continual growth in both research and commercial applications. Attractive features such as their small size, light weight and low cost are a strong driver of this growth. However, these factors also bring about some drawbacks. The light weight and small size means that small UAVs are far more susceptible to performance degradation from factors such as wind gusts. Due to the generally low cost, available sensors are somewhat limited in both quality and available measurements. For example, it is very unlikely that angle of attack is sensed by a small UAV. These aircraft are usually constructed by the end user, so a tangible amount of variation will exist between different aircraft of the same type. Depending on application, additional variation between flights from factors such as battery placement or additional sensors may exist. This makes the application of optimal model based control methods difficult. Research literature on the topic of small UAV control is very rich in regard to high level control, such as path planning in wind. A common assumption in such literature is the existence of a low level control method which is able to track demanded aircraft attitudes to complete a task. Design of such controllers in the presence of significant wind or modelling errors (factors collectively addressed as lumped disturbances herein) is rarely considered. Disturbance Observer Based Control (DOBC) is a means of improving the robustness of a baseline feedback control scheme in the presence of lumped disturbances. The method allows for the rejection of the influence of unmeasurable disturbances much more quickly than traditional integral control, while also enabling recovery of nominal feedback con- trol performance. The separation principle of DOBC allows for the design of a nominal feedback controller, which does not need to be robust against disturbances. A DOBC augmentation can then be applied to ensure this nominal performance is maintained even in the presence of disturbances. This method offers highly attractive properties for control design, and has seen a large rise in popularity in recent years. Current literature on this subject is very often conducted purely in simulation. Ad- ditionally, very advanced versions of DOBC control are now being researched. To make the method attractive to small UAV operators, it would be beneficial if a simple DOBC design could be used to realise the benefits of this method, as it would be more accessible and applicable by many. This thesis investigates the application of a linear state space disturbance observer to low level flight control of a small UAV, along with developments of the method needed to achieve good performance in flight testing. Had this work been conducted purely in simulation, it is likely many of the difficulties encountered would not have been addressed or discovered. This thesis presents four main contributions. An anti-windup method has been devel- oped which is able to alleviate the effect of control saturation on the disturbance observer dynamics. An observer is designed which explicitly considers actuator dynamics. This development was shown to enable faster observer estimation dynamics, yielding better disturbance rejection performance. During initial flight testing, a significant aeroelastic oscillation mode was discovered. This issue was studied in detail theoretically, with a pro- posed solution developed and applied. The solution was able to fully alleviate the effect in flight. Finally, design and development of an over-actuated DOBC method is presented. A method for design of DOBC for over actuated systems was developed and studied. The majority of results in this thesis are demonstrated with flight test data.

M.A. / Disappointments in romantic relationships can have distressing and prolonged cognitive, emotional and behavioural effects. This study explored such disappointments in the form of betrayal, rejection and the accompanying beliefs, emotions and behaviours using the Rational Emotive Behaviour Therapy theoretical framework. A theory-building positivistic case study design was implemented. Five participants completed a quantitative measure of REBT beliefs, the Shortened General Attitudes and Beliefs Scale, and participated in a semi-structured interview. The experience of a romantic betrayal or rejection elicited greater irrational than rational beliefs, and more dysfunctional than functional outcomes (emotions and behaviours) for each participant. The implications for clinical practice are discussed using the REBT theoretical framework.

M.A. (Social psychology) / The purpose of this study was to determine whether parental rejection and a characteristic attributional style contribute to childhood depression. After a review of existing literature on the relationship between depression,parental rejection and attributional style, it was hypothesized that parental rejection and attributional style would affect childhood depression, and therefore contribute to childhood depression. In order to test the hypothesis, children and their parents were tested. Out of the initial sample, 50 depressed and 50 non-depressed children as well as their parents undergone further tests. The tests used in this study were the CDI, DSRS, PPI and the KASTAN for the children, and the BDI, ASQ and the PARI for the parents. The results of this study indicated that parental rejection does contribute to childhood depression. There was, however, not much support provided by the data for the contribution of a characteristic attributional style to childhood depression. This would imply that further research in this area is necessary.

This thesis investigates the revenue management (RM) problem encountered in an airport carpark of finite capacity, where the available parking spaces should be sold optimally in advance in order to maximise the revenues on a given day. Customer demand is stochastic, where random pre-booking times and stay lengths overlap with each other, a setting that generates strong inter-dependence among consecutive days and hence leads to a complex network optimisation problem. Several mathematical models are introduced to approximate the problem; a model based on a discrete-time formulation which is solved using Monte Carlo (MC) simulations and two single-resource models, the first based on a stochastic process and the other on a deterministic one, both developed in continuous-time that lead to a partial differential equation (PDE). The optimisation for the spaces is based on the expected displacement costs which are then used in a bid-price control mechanism to optimise the value of the carpark. Numerical tests are conducted to examine the methods’ performance under the network setting. Taking into account the methods’ efficiency, the computation times and the resulting expected revenues, the stochastic PDE approach is shown to be the preferable method. Since the pricing structure among operators varies, an adjusted model based on the stochastic PDE is derived in order to facilitate the solution applicable in all settings. Further, for large carparks facing high demand levels, an alternative second-order PDE model is proposed. Finally, an attempt to incorporate more information about the network structure and the inter-dependence between consecutive days leads to a weighted PDE scheme. Given a customer staying on day T, a weighting kernel is introduced to evaluate the conditional probability of stay on a neighbouring day. Then a weighted average is applied on the expected marginal values over all neighbouring days. The weighted PDE scheme shows significant improvement in revenue for small-size carparks. The use of the weighted PDE opens the possibility for new ways to approximate network RM problems and thus motivates further research in this direction.

M.Cur. (Advanced Psychiatric Nursing Science) / I am a survivor of a multiple sexual traumas, some more brutal than others but the scar is just as deep. This happened in my teens and into my young adulthood years. During those years I perceived a great lack of support and mostly rejection from my mother, and saw the reoccurrence of these sexual traumas as a result of this. But through growth and education I have learned that my mother did the best that she could at that time, given her position and circumstances. I have also been able to acknowledge and accept my responsibilities in my past and, therefore, my future. It was a very difficult process to conquer, for both my mother and I, but it is worth it and it is possible. Today my mother is my best friend and my biggest fear is life without her. Understanding and overcoming this challenge has eased a lot of emotional pain that I had carried with me over the years and so I wished the same could happen for other women that might have perceived rejection from their mothers. To begin the journey, this research study was born. The purpose of my research study was to explore and describe the life stories of young women who have perceived rejection from their mothers, in order to formulate guidelines and recommendations that may help them to deal effectively with their situation. My research study also aims to stimulate interest among other role players within the academic field, communities and the health profession to assist with other meaningful interventions with regard to this challenge. My research study was implemented in two phases. I used a qualitative, explorative, and contextual research design in my approach. The first phase focused on the life stories of young women who have perceived rejection from their mothers. The second phase dealt with the findings gathered from the field work from which the guidelines and recommendations were formulated to assist the participants in coping with the challenge of their life stories. Eight in-depth interviews were conducted, transcribed and analysed by means of Tesch’s method of analysis. Guba’s method of trustworthiness was used together with the services of a well-experienced independent coder, to establish validity and reliability of the data. A signed voluntary consent form was obtained from the participants beforehand for participation in the research study, as well as for the conduction and recording of the interviews. Thematic analysis was used where themes and the central storyline were identified according to the life stories told in each individual interview. The limitations of my research study were also discussed. It was found that more research studies need to be conducted into this phenomenon in order to formulate other effective intervention strategies to help address the challenges that arise from the phenomenon. Recommendations for psychiatric nursing research, psychiatric nursing education, and psychiatric nursing practice were suggested. The knowledge and expertise of a language editor was also used in the research study.
