Streszczenie:

Pilot Induced Oscillations (PIO) are described as pilot-aircraft dynamic couplings which can lead to instability in an otherwise stable system. Previous and ongoing research has attempted to explain, predict, and avoid such oscillations. In contrast to other research, this effort backs away from pilot models and PIO avoidance and focuses on the characteristics of the pilot before, during, and after a PIO. Often, PIO''s can be explained by limit cycles occurring in a non-linear system where the non-linearities cause a sustained, constant amplitude oscillation. The primary instigators in such a PIO are usually a non-linear element (i.e. rate limit saturation) and a trigger event (i.e. pilot mode switching or increased pilot gain). By performing analysis in the frequency domain, determining such oscillations becomes easier. Using spectrograms and power spectral density functions, the frequency content of a signal in the pilot-aircraft system can also be investigated.

An F-14 flight test was recently performed where the hydraulic system was modified to determine the feasibility of trying to recover the aircraft (land on carrier) during such an extreme hydraulic failure. During testing, a severe PIO occurred because of the tight tracking task used during aerial refueling. While performing spectrograms and power spectral analysis, an increase in power concentration at the PIO frequency was observed.

With a linear approximation of the F-14 aircraft dynamics, a closed-loop system containing the aircraft, actuator, and pilot dynamics is developed so that limit cycle analysis can be performed. With stable limit cycle solutions found possible, a pilot-in-the-loop simulation is performed to verify the pilot model used in limit cycle analysis. Using the flight test data, limit cycle analysis, and pilot-in-the-loop simulation, a connection between variation in pilot behavior and PIO predicted by the increase in power concentration is investigated.

The resulting connection showed that an increase in pilot gain along with a transition from observing pitch attitude to pitch rate are the possible trigger events causing the PIO. The use of spectrograms as a PIO predictor is shown to be possible, provided the necessary calculations can be completed in real-time.

This thesis is intended to highlight the difficulty and different methods of training airline pilots. It can also serve as a guide for anyone who would like to become a transport pilot and he has not met flying yet. Further the thesis includes a balance sheet of the training strategy in financial terms and their own possibilities of the adept, that anyone who considers the traffic flying should think of well before starting. The thesis also includeds the return on investment, which may be crucial in any decision-making. In addition, it addresses the issue of loans and the pilot takes a look at new trends in aviation

Streszczenie:

The work of pilot is one of the most difficult activity, that why the training is difficult as well. The process of professional training includes a lot of instruments and devices. The level of training should mainly guarantee safety. Accident analysis and preconditions shows that factors such as the mistakes in flight operations, errors in piloting techniques and operation of aviation equipment determines the overall accident rate. This causes the need to improve the organization of flight training for flight crews.

The Murdoch university pilot plant is widely used throughout the instrumentation and control engineering major. This plant allows students to implement the fundamental theoretical knowledge learnt in earlier years on a real industrial plant. This miniaturized Bayer process plant, which runs cutting edge control hardware and software, is a core asset to Murdoch University and it is essential that the system be maintained to the highest of standards. This project aims to maintain the operation of the plant, while expanding the system by implementing an automation program. The implementation of this project will be contributing to previous works by a number of previous students and will finish this particular proposal. The design requirements of this project include a system that demonstrates the functionality of the plant. This program must include transit of water through the system and adequately provide an example of the functionality of the system. Secondary objectives include maintaining the plant between long periods of dormancy and this will include instrument manipulation so all sections of the plant stay active during this period. This proposal was solved by carefully designing the automation program, simulating different aspects of the system and carrying out intense testing. The automation program was successfully implemented and provided adequate operation to demonstrate the functionality of the pilot plant. This program also met the design requirements to cycle the instruments to reduce maintenance issues over the long periods of dormancy. Other accomplishments that were undertaken throughout the semester include the improvement and documentation of the system code, hardware additions, component replacement and servicing. The research undertaken over the semester has generated many other ideas that would improve the system further. These have been assessed and work has commenced on the execution of these ideas, however future work is needed to finish these goals. These include finishing the code restructuring of the entire plant, according to the generated programming standards, implementation of new hardware and the completion of the instrument servicing.

Streszczenie:

At a time of increased use and competitiveness amongst U.S. regional airlines, and the growing pilot shortage, regional air carriers and pilots alike lack proper understanding how pilot commutes by airplane affect satisfaction with life. There are numerous studies on how commuting by vehicle, bicycle, mass transit system, or walking (traditional commute) to and from work affects one’s satisfaction with life. There are no identified studies which investigate regional airline pilots’ commute by airplane and its affect on satisfaction with life.

The purpose of this study was to gain knowledge on regional airline pilot commutes, how commuting affects regional pilots’ satisfaction with life, and to explore why regional airline pilots choose to commute. This study used both qualitative and quantitative measures to accomplish this task by imploring a mixed methods exploratory sequential design. The two research questions were what is the variation in the Satisfaction With Life Scale scores between different groups of regional pilots and what aspects of pilot commuting are related to traditional commuting?

This study used previous related research and regional airline pilot qualitative interviews to build a quantitative survey to measure satisfaction with life. The survey was distributed to a large regional airline to get a representative pilot population sample response. Statistical analysis was conducted on the responses which looked for significance between different groups of regional airline pilots.

Results from a t-test indicated that there is a significant difference in Satisfaction With Life Scores for regional pilots that are able to traditionally commute to their domicile vs. regional pilots who commute by airplane to their domicile. Further t-test results indicated that there is a significant difference in satisfaction with life for airplane commute captains vs. traditional commute captains, and airplane commute captains vs. traditional commute first officers. When only airplane commute pilots were analyzed, there are significant differences in satisfaction with life for pilots that commute over 43.33 hours a month (equivalent to one hour, one way traditional commute), and a one way airplane commute of two or more legs. A Between-Groups ANOVA indicated that commuting the day before a trip begins and commuting the day after a trip ends (un-commutable trip) produces a less satisfied pilot compared to trips that are commutable at the beginning, end or both ends.

Mestrado em Microbiologia
O HPV é o vírus sexualmente transmissível mais comum em todo o mundo, tendo uma forte relação causal com o cancro do colo do útero. A infeção por HPV é a causa necessária, mas não suficiente do cancro do colo do útero, em todo o mundo. Países em desenvolvimento têm maior taxa de infeção por HPV e cancros relacionados sendo que a prevalência da infeção por HPV global varia por país, região dentro do mesmo país e subgrupo da população sendo que os genótipos de HPV podem apresentar diferentes distribuições de acordo com a região geográfica. Mulheres africanas são desproporcionalmente afetadas com HPV e têm uma maior taxa de morbidade de cancro do colo do útero. Devido à falta de conhecimento sobre o HPV, são necessários rastreios, medidas preventivas relacionadas com cancros do colo do útero, programas de tratamento, acompanhamento posterior e imunização com vacinas contra o HPV. O objetivo deste trabalho foi determinar a prevalência da infeção por HPV e caracterizar a frequência dos vários genótipos de HPV numa população de mulheres angolanas, usando a Polymerase Chain Reaction (PCR), Restriction Fragment Length Polymorphism (RFLP) e realizar uma revisão sistemática sobre a prevalência e distribuição genotípica de HPV no continente africano. Os resultados mostram que a prevalência de HPV em mulheres angolanas foi 20,9% (14/67), que foi muito baixa em comparação com outros países da África Central. Os genótipos mais prevalentes foram HPV-61 (35.7%), HPV-16 (14.3%), HPV-33, -56, -58a, -58b, -70c, -72, -84 (7,1%). Também se verificou que dentro de regiões geográficas africanas podemos esperar diferentes taxas de eficácia resultantes de uma vacinação das populações utilizando as vacinas atualmente existentes. Em conclusão, este estudo fornece as primeiras estimativas da prevalência de HPV e sua distribuição entre as mulheres angolanas, demonstra que a epidemiologia da infeção por HPV em Angola é diferente de outras regiões do mundo. Sendo que vacinação específica para cada área geográfica é necessária, para evitar doenças relacionadas com o cancro do colo do útero e outras doenças relacionadas com o HPV. Os diferentes dados observados entre nosso estudo e os estudos utilizados para comparar os resultados podem refletir a diferenças na distribuição dos tipos HPV em diferentes populações ou podem ser por causa de diferenças entre a sensibilidade dos métodos utilizados.
Worldwide HPV is the most common sexually transmitted virus that has a strong causal relationship with cervical cancer (CC). Persistent HPV infection is the necessary but non-sufficient cause of CC worldwide. Developing countries have the highest burden of HPV infection and related cancers and the prevalence of HPV infection overall varies by country, region within country, population subgroup and HPV genotypes may exhibit differing distributions according to geographic region. African women are disproportionately impacted with HPV and have a higher rate of morbidity of cervical cancer. Due to lack of knowledge about HPV, smears and cervical cancer-related preventive measures, treatment adherence and follow-up and immunization programs of HPV vaccines are needed. The aim of this work was determine the prevalence of HPV infection and characterize the frequency of multiple HPV genotypes in Angola using Polymerase Chain Reaction (PCR) and Restriction Fragment Length Polymorphism (RFLP) and to perform a systematic review on the prevalence and genotypic distribution of HPV in the African continent. The results show that HPV prevalence in Angolan women was 20.9% (14/67) which was very low compared with other countries of Central Africa. The most prevalent genotypes were HPV-61(35.7%), HPV-16(14.3%), HPV-33, 56, 58ª, 58b, 70c, 72, 84 (7.1%). It also shows that within African geographic regions we may expect different rates of efficacy resulting from a putative vaccination of populations using the currently existing vaccines. In conclusion, this study provides the first estimates of the prevalence of HPV and distribution among women from Angola and demonstrates that the epidemiology of HPV infection in Angola is different from that of other world regions. Specific area vaccinations are needed to prevent cervical cancer and the other HPV- related diseases. The observed different data between our study and the studies used to compare the results might reflect true differences in the distribution of HPV types in different populations or might be because of differences in the sensitivity of the methods used.

Contém errata
Este trabalho de investigação teve como principal objetivo identificar o perfil de âncoras de carreira dos Oficiais Pilotos Aviadores da Força Aérea Portuguesa e verificar como é que o mesmo varia em função da situação pessoal/familiar e profissional do piloto. Simultaneamente foi averiguado a existência de relações destas âncoras com a carreira em progressão horizontal. A amostra deste estudo, recolhida por conveniência, é composta por 72 indivíduos, correspondente a 38,3% da população-alvo existente. Quanto à recolha de dados, foi seguida uma metodologia quantitativamente mista, utilizando um inquérito por questionário para a obtenção destes. O instrumento utilizado baseia-se no Career Orientations Inventory, desenvolvido por Schein (1990), tendo este sido adaptado para melhor se ajustar ao contexto militar. Para o tratamento dos dados quantitativos foi utilizado o programa estatístico SPSS e realizada uma análise de conteúdo às perguntas qualitativas existentes. Foi concluído que as âncoras Estilo de Vida e Competência Técnica/Funcional são as que se encontram mais desenvolvidas, sendo a Competência de Gestão a âncora com os valores inferiores. Verificaram-se diferenças significativas consoante fatores demográficos, como a idade, o estado civil e o número de descendentes, e fatores profissionais, como a qualificação, o número de horas de voo bem como a duração do empenhamento em destacamentos nacionais e missões internacionais. Adicionalmente comprovou-se a existência de correlações com a carreira em progressão horizontal, proporcionadora de um alinhamento com o recente conceito de carreiras Proteanas. As contribuições do estudo reforçam a importância da valorização dos Recursos Humanos, identificados como o principal recurso estratégico das organizações. Deste modo, a identificação das âncoras de carreira dos seus colaboradores constitui-se como uma importante ferramenta de gestão para a aplicação de medidas mais ajustadas, tendo como intuito o alcance de melhores resultados e elevados níveis de satisfação. Finalmente, são apresentadas as limitações encontradas no decorrer do presente estudo assim como sugestões para investigações futuras.
The aim of this investigation was to identify the career anchor profile of the Portuguese Air Force military pilots and to verify how it varies, according to the pilot’s personal/family and professional situation. Simultaneously, the existence of relationships between these anchors and the horizontal career progression was ascertained. A convenience sample of 72 individuals was collected, which corresponds to about 38.3% of the existing target population. For the data collection, a mixed quantitative methodology by means of a survey was followed. The used instrument was based in the Career Orientations Inventory, developed by Schein (1990), which was adapted to better fit the military context. The statistical analysis software program SPSS was used to process all the quantitative data and a content analysis of the qualitative questions was also conducted. It was concluded that the Lifestyle and Technical/Functional Competence anchors are the most developed and General Managerial Competence showed the lowest values. There were significant differences based on demographic factors, such as age, marital status and number of descendants, as well as professional factors, such as the pilot’s qualifications, the number of flight hours and the duration of national deployments and international missions. Additionally, the existence of correlations with the horizontal progression career was verified, providing an alignment with the recent concept of Protean careers. The study’s contributions reinforce the importance of valuing Human Resources, which are identified as the main strategic resource of organizations. Therefore, the identification of the career anchors if its employees is an important management tool for the application of better adjusted measures, aiming to achieve better results and higher levels of satisfaction. Lastly, the limitations encountered during the formulation of the present study are presented, as well as some suggestions for future investigations.

This thesis responds to two distinct claims about drone (or remotely piloted aircraft) pilots. The first is the general claim that the martial virtues function as a kind of role morality for soldiers; the second, that drone pilots, based on the absence of personal risk and their distance from the battlefield, are unable to meet the demands of such a role morality. Chapter One explains what is meant by role morality, and determines whether the martial virtues do in fact function in a role morality capacity. The second chapter applies this general conception of a role morality for soldiers to military drone pilots in particular. This investigation finds that, insofar as "soldier" is in fact a role that generates a role morality, military drone pilots are as capable of meeting the demands of such a role morality as other military members. The second half of the thesis challenges the premise that drone pilots do not face personal risk. Chapter Three identifies psychological risk among drone pilots and seeks to determine how this kind of non-physical risk may affect the cultivation of the martial virtues. The fourth chapter argues that by placing military drone pilots within domestic territory, drone-capable militaries (such as the US military) have redrawn the battlespace such that it includes the drone operators, wherever they may be, and that as a result, drone pilots do in fact face some physical risk. Finally, in closing, this thesis presents a positive account of the martial virtues that enables military ethicists and strategists to bring centuries of philosophical investigation to bear on contemporary military issues

The aim of this thesis is to develop a real time PIO detection and mitigation system that consists of a detector based on short time Fourier transform(STFT) and autoregressive model(ARX) with exogenous inputs, together with an adaptive controller based mitigation system. The system not only detects the traditional PIO characteristics but also focuses on the trend of pilot behaviour by calculating the rate of change in the open loop crossover frequency. In the detection system, a sliding windowed STFT method was applied to identify the frequency and phase characteristics of the system via processing the signal of pilot input and aircraft state. An ARX model was also applied to get the rate of change of the crossover frequency. After detection, a PIO cue was shown on the primary flight display. A scheduled gain controller was coupled to provide PIO mitigation by varying stick input gain. Compensatory and tracking tests for the evaluation of this system were performed using a quasi-linear Boeing-747 aircraft model including nonlinear command gearing and actuator rate-limiting. Bandwidth and Gibson criteria were used to design PIO prone control laws for system evaluation experiments. Results from PIO tests conducted on desktop PCs were presented. These were analyzed and compared with those obtained from implementing the Real-time Oscillation Verifier module available in literature.

This report is a first practical study of micro valves for hydraulics, manufactured by Microstaq Inc. who uses, for hydraulics, new materials and new actuating technologies. The purpose is to evaluate if, in the future, there is any possibility of complementing or exchanging the classical use of electro magnetic solenoids in electro hydraulic applications with this new technology. The valves studied are of MEMS-type (Micro Electro Mechanical Systems), which are etched out of silicon and has an electro thermic actuation. During the study it showed that this new valve technology had some teething troubles. The valves had proplems managing high pressure drops, both regarding strength of materials and performance. If you let the manufacturers further develop this technology there are great potentials for using this in future hydraulic systems.

Streszczenie:

There is presently no wildfire model developed for Swedish conditions, only a fire danger rating system (FWI) has been developed for Swedish conditions. The demand for a wildfire model has not been great in the past in Sweden but the climate changes now taking place increases the risk of large and intensive wildfires in Sweden. The need for additional and better tools for sizing-up wildfires will be in great demand in the future. This pre-study is aimed at: - Presenting what has been done in the wildfire modeling field during the years and mainly the last twenty years. - Giving recommendations on the continued work with developing a Swedish wildfire model. The method that was used was literature and article survey. The study also looks into the required input data for a wildfire model and the input data available at the moment. This issue is highly crucial as the quality of the output of a wildfire model is depending upon the quality of the input data. During the study, a primitive wildfire model was constructed and refined in order to get an insight in the complexities and problems with developing an operational model. The following characterization of wildfire models was used during the study: - Statistical models: based primarily on statistics from earlier or experimental fires. They do not explicitly consider the controlling physical processes. - Semi-empirical models: based on physical laws, but enhanced with some empirical factors, often by lumping all physical mechanisms for heat transfer together. - Physical models: based on physical principles and distinguishing between physical mechanisms for heat transfer. The statistical models make no attempt to involve physical processes, as they are merely a statistical description of test fires. Thus the lack of a physical basis means that statistical models must be used carefully outside the test conditions. Semi-empirical models are often based on conservation of energy principles but do not make any difference between conduction, convection and radiation heat transfer. The semi-empirical model has low computational requirements and includes variables that are generally easy to measure in the field. So despite the issue with limited accuracy, the speed and simplicity of these models make them useful for operational use. Physical models have the advantage that they are based on known relationships and thus facilitating their scaling. Thus we can expect that physical models would provide the most accurate predictions and have the widest applicability. But the work on physical models is suffering of for example the lack of understanding of several processes, such as the characterization of the chemical processes taking place during combustion, the resulting flame characteristics and the isolation and quantification of physical processes governing heat transfer. The input data available today are generally not detailed enough for physical models. As a result, a very detailed physical model will still only give imprecise predictions. As better and more detailed input will be available, the use of physical models will be more justified. A semi-empirical model is recommended being developed in Sweden. This conclusion is based upon the following factors: - The accuracy of a semi-empirical model is generally much better than for a statistical model, also the use of a semi-empirical model is much wider than the use of a statistical model. - The amount of work required for developing a semi-empirical model will not differ much from the amount of work required for a statistical model. In both cases a number of test fires will have to be conducted to define and calibrate a number of fuel models representative of Sweden. - Presently the performance and application of physical models is not at an acceptable level (due to for example the complexity which they are to model and the computational capabilities of the PC’s of today) for operational use. The semi-empirical model for Sweden is recommended to be built upon Swedish conditions (i.e. built upon the type of vegetation found in Sweden) instead of trying to retrofit the local Swedish conditions into an existing model. This would most likely give the best output for Swedish conditions. A system for better input data - weather and fuel data – should be worked on as well. This could for example take advantage of the results of the very promising “Alarm”-project that is being conducted in western part of Sweden. Regarding the issue on better fuel data, new technology for satellite images or aerial photos and image classification techniques must be monitored as one major problem to be solved is distinguishing between the canopy fuel and the ground fuel. For more specific conclusions and reflections, please see the analysis and discussion, and conclusions sections of this report.

"Karmic Buyback: A Pilot Program", a screenplay, is the story of Oliver Harker, a water resources engineer in his early thirties, adrift in a world of lost social connections. Aside from this work, which he describes as "just a lot of redundant paperwork," his only connection to the outside world is his exuberant younger brother Van. With no father to speak of, and harboring long term resentment against his mother who ran away to Africa the day after Van's high school graduation, Oliver's defining tragic moment came three years earlier. It was then he discovered Eva, the woman he planned to marry, cheating with an old flame. Isolating himself from his few remaining friends, Oliver has become a short-tempered, unbearable grump. Meanwhile Eva, unbeknownst to Oliver, has recently died. She wakes to find herself in a strange, antiseptic afterlife where she is given the opportunity to repair some of the bad karma she accumulated in her short life, specifically in regard to Oliver. As Van begins to help him reestablish social ties, an accident which lands Oliver in the hospital finally draws their mother back across the Atlantic. Oliver must decide between Eva, in her foolish attempts to win him back as a result of the ultimately misguided Karmic Buyback Pilot Program, and the real people who love him.

The Engineering Pilot plant at Murdoch University is one of the unique process facilities that currently exists in any universities in Australia. It provides an opportunity for Instrumentation and Control engineering students studying at Murdoch University to explore various control methods and strategies to extend their range of knowledge in this area with the aid of physical instruments and software provided in the pilot plant. The purpose of this thesis project is to devise a strategy to improve the process measurements in the pilot plant through investigation of theory and implementation of Steady State Data Reconciliation and Online Dynamic Data reconciliation and to observe and testify if data reconciliation can improve process control performance with a more accurate set of measurements This project has been divided into three different stages with the first stage being, the understanding of data reconciliation, understanding of DR using existing case studies, followed by the investigation of the physical implementation and foundation work of data reconciliation in the pilot plant, and finally the testing and conclusion as to whether or not data reconciliation can improve the process measurements and consequently the control results. Results of the implementation of data reconciliation indicated the improvement of process measurements. Non-Linear Tank and Needle Tank have shown considerable measurement improvement with the implementation of data reconciliation on the measuring variables of both tanks. Flow rate in, flow rate out, and levels of both tanks were monitored and measured except the flow going into Non-linear Tank were estimated as there were no measuring device available for that particular variable. Ball Mill Tank and Cyclone Underflow Tank were also investigated with a recycle stream, steady state data reconciliation have also been implemented at this process system and helps to improve a better understanding of data reconciliation applications. Dynamic data reconciliation were also implemented at the Needle Tank in the pilot plant for case study investigation, the results obtained is of what was expected and proved that DDR can provide significant contribution in terms of improving process control performance of the process system in the future.

Streszczenie:

The development of large lightweight airframes has resulted in what used to be high frequency structural dynamics entering the low frequency range associated with an aircraft’s rigid body dynamics. This has led to the potential of adverse interactions between the aeroelastic effects and flight control, especially unwanted when incidents involving failures or extreme atmospheric disturbances occur. Moreover, the pilot’s response in such circumstances may not be reproducible in simulators and unique to the incident. The research described in this thesis describes the development of a pilot model suitable for the investigation of the effects of aeroelasticity on manual control and the study of the resulting airframe loads. After a review of the state-ofthe- art in pilot modelling an experimental approach involving desktop based pilot-in-the-loop simulation was adopted together with an optimal control based control-theoretic pilot model. The experiments allowed the investigation of manual control with a nonlinear flight control system and the derivation of parameter bounds for single-input-single-output pilot models. It was found that pilots could introduce variations of around 15 dB at the resonant frequency of the open loop pilot-vehicle-system. Sensory models suitable for the simulation of spatial disorientation effects were developed together with biomechanical models necessary to capture biodynamic feedthrough effects. A detailed derivation and method for the application of the modified optimal control pilot model, used to generate pilot control action, has also been shown in the contexts of pilot-model-in-the-loop simulations of scenarios involving an aileron failure and a gust encounter. It was found that manual control action particularly exacerbated horizontal tailplane internal loads relative to the limit loads envelope. Although comparisons with digital flight data recordings of an actual gust encounter showed a satisfactory reproduction and highlighted the adverse affects of fuselage flexibility on manual control, it also pointed towards the need for more incident data to validate such simulations.

Nowadays two main types of protection schemes widely used in protection of transmission lines are: distance protection and differential protection schemes. However, it has been noticed from industrial practice that the distance protection scheme used today generally is limited in tripping speed and selectivity. Also differential protection scheme is influenced by the time synchronization of samples in both relays installed at transmission line terminals. On the other hand, among various pilot protection schemes for protection of Extra High Voltage (EHV) / Ultra High Voltage (UHV) transmission lines, the schemes which use communication link only for exchange of local decision making about faults’ status are not affected by time synchronization. This master thesis is dealing with the issue of developing reliable and fast fault detection scheme for protection of EHV/UHV transmission lines which is a requirement in modern power systems. The protection algorithm proposed in this thesis is based on the detection and analysis of traveling waves on transmission lines at inception of the faults. This algorithm relies on directional comparison between initial arrivals of traveling waves at each end of the protected line. This will determine whether or not a fault is inside the protected zone. In addition to, based on high voltage transmission network protection requirements proper phase selection algorithm is developed to handle single- phase tripping. Finally, by simulations carried out in PSCAD environment practical design considerations for implementing the new developed protection algorithm in a numerical relay unit is investigated. The results of simulation show that the proposed pilot protection scheme solves several issues encountered by using the conventional schemes and provide reliable and high speed protection for transmission lines.

Streszczenie:

The development of large lightweight airframes has resulted in what used to be high frequency structural dynamics entering the low frequency range associated with an aircraft’s rigid body dynamics. This has led to the potential of adverse interactions between the aeroelastic effects and flight control, especially unwanted when incidents involving failures or extreme atmospheric disturbances occur. Moreover, the pilot’s response in such circumstances may not be reproducible in simulators and unique to the incident. The research described in this thesis describes the development of a pilot model suitable for the investigation of the effects of aeroelasticity on manual control and the study of the resulting airframe loads. After a review of the state-ofthe- art in pilot modelling an experimental approach involving desktop based pilot-in-the-loop simulation was adopted together with an optimal control based control-theoretic pilot model. The experiments allowed the investigation of manual control with a nonlinear flight control system and the derivation of parameter bounds for single-input-single-output pilot models. It was found that pilots could introduce variations of around 15 dB at the resonant frequency of the open loop pilot-vehicle-system. Sensory models suitable for the simulation of spatial disorientation effects were developed together with biomechanical models necessary to capture biodynamic feedthrough effects. A detailed derivation and method for the application of the modified optimal control pilot model, used to generate pilot control action, has also been shown in the contexts of pilot-model-in-the-loop simulations of scenarios involving an aileron failure and a gust encounter. It was found that manual control action particularly exacerbated horizontal tailplane internal loads relative to the limit loads envelope. Although comparisons with digital flight data recordings of an actual gust encounter showed a satisfactory reproduction and highlighted the adverse affects of fuselage flexibility on manual control, it also pointed towards the need for more incident data to validate such simulations.

PILOT, pour Polarized instrument for Long Wavelength Observation od the Tenuous interstellar medium, est une expérience d'astrophysique embarquée sous ballon stratosphérique dont l'objectif principal est la mesure de l'émission polarisée de la lumière par les poussières du milieu interstellaire. Cette expérience permettra la cartographie du champ magnétique galactique à une résolution de l'ordre de la minute d'arc à une longueur d'onde de 240 µm (1.2 THz). La détection de la polarisation est réalisée à l'aide d'un polariseur placé à 45° dans le faisceau, le décomposant en deux composantes polarisées orthogonales chacune détectées par quatre matrices de 256 bolomètres, et d'une lame demi-onde rotative. Les observations de PILOT s'inscrivent en complément des observations effectuées à l'aide du satellite Planck, avec une meilleure résolution angulaire, et en complément des observations en polarisation menées au sol avec des instruments comme NIKA2 installé sur le télescope de 30m de l'IRAM. Cette thèse se divise en trois parties, la première étant consacrée à la présentation du contexte scientifique qui entoure l'instrument ainsi qu'à la présentation de l'instrument et des deux campagnes de vol ayant eu lieu à Timmins au Canada et Alice Spring en Australie. La deuxième partie se focalise sur les performances en vol de PILOT et la troisième partie présente le pipeline mis en place pour le traitement des données ainsi que les premières cartes en polarisation obtenues

In this thesis, we develop and apply a number of theoretical models describing the dynamics of a droplet walking on a vibrating liquid bath. We first review the hierarchy of theoretical models developed to describe this system. We begin with the stroboscopic model of Oza et al. (2013), and elucidate the role of spatial wave-damping and the effect of the droplet's vertical dynamics. We then extend the boost model of Bush et al. (2014), valid in the weak-acceleration limit, demonstrating its connection to the Rayleigh oscillator model of Labousse & Perrard (2014). We extend the boost framework in order to consider droplet interactions with slowly-varying topography, and compare our model predictions with the results of an accompanying experimental study. Particular attention is given to outlining the physical limits in which the topographical effects may be captured by an effective force. We also investigate theoretically the dynamics of hydrodynamic spin lattices, and demonstrate that their collective behavior is captured by a generalized Kuramoto model, which we explicitly derive from the boost framework. Finally, motivated by the statistical signature reported in the trajectories of droplets interacting with wells by Sáenz et al. (2020), we consider the stability of the steady walking state. By considering a generalized pilot-wave framework that allows us to explore parameter regimes beyond that accessible in the laboratory, we discover states in which the walker's speed oscillates over a scale comparable to the Faraday wavelength, in addition to a regime in which walker motion is unstable and undergoes random-walk-like motion. We demonstrate how either of these two mechanisms may lead to the emergence of quantum-like statistics with the signature of the pilot wavelength from the pilot-wave dynamics. We conclude with a discussion of the implications of this work and suggest fruitful directions of future research.

The most commonly used tests for the evaluation of perceptual motor function of children in South Africa are the Southern California Sensory Integration Tests (Ayres, 1972) and Southern California Postrotary Nystagmus Test (Ayres, 1975). These particular tests were revised, changed and restandardized in 1989. For various reasons the new form, Sensory Integration and Praxis Tests (Ayres, 1989), is not feasible for use in South Africa. It has thus become imperative to develop tests in South Africa that can replace these tests. The South African Institute of Sensory Integration appointed working committees in various sectors of the country to develop a test for the South African population. The candidate decided to develop a somatosensory Test which could be used as part of a South African test of sensory integration. A test was designed and constructed, based on the model used by Ayres in the Southern California Sensory Integration Tests. This test comprises five subtests, i.e. Non-vestibular Proprioception (in the first phase of the study this subtest was named Kinesthesia), Finger Recognition, Form Recognition, Two Point Discrimination and Tactile Stimuli Placement tests. This proposed test was used in the field by seven voluntary field workers. They each recruited a sample of convenience and administered the proposed test to 58 children. A self-administered questionnaire was completed for each test administered completed to evaluate the mechanics of the test. The data obtained from the questionnaires were statistically analysed and from this the candidate could draw conclusions about changes necessary for the test. Suggested changes were implemented. These included shortening the test, changing verbal instructions, adapting some parts of test items, reorganising the score sheet and changing the instruction manual accordingly. A pilot study was conducted to determine validity and reliability of the proposed test. A representative sample (n = 114) was recruited from the Sub A population in the Durbanville and Kraaifontein area of the Northern suburbs of the Cape Town Metropolitan Area. A comparative study was done to validate the proposed test, using the Southern California Sensory Integration Tests as a gold standard. The Two Point Discrimination test was excluded from this validation study as there is no corresponding test of the SCSIT. Results were compared and levels of sensitivity and specificity were established. In general, higher levels of specificity than sensitivity were obtained. The Form Recognition test had the highest sensitivity level (60%) and in the case of the Finger Recognition test statistically significant differences were obtained between means (p = 0.006). Thirty children from the group of 114 were tested by two testers to establish the reliability coefficient. The Form Recognition test had the highest coefficient (0.83).

The Honeywell Experion Process Knowledge System (PKS) and Pilot Plant are both unique and invaluable teaching tools used in Instrumentation and Control Engineering at Murdoch University. The Pilot Plant is one of the most industry relevant practical components, which can be used to apply and develop theoretical control knowledge. Therefore it is essential to maintain and upgrade the Pilot Plant’s operability and performance. The main purpose of this thesis is to extensively analyse the current condition of the Pilot Plant, propose and organise an agenda to fix faulty components, install new components or new coding to ensure safer operations to protect users as well as equipment, and improve its working condition. To successfully achieve these goals, the project holder should have a moderate knowledge about the Pilot Plant server, Experion supervisory control system and the Pilot Plant’s C300 controller. This knowledge is usually obtained from working and practicing on the Experion Teaching System, which is the first aim to start the project. As the Experion Training system was available for 3 months the work done to this system was limited. To improve some of the tutorial exercises and the documentation prepared by previous students, a simulated Experion system using a C300 controller and a Human-Machine Interface (HMI) page for the controlled system was developed and properly documented. The simulated system can use Object Linking and Embedding for Process Control (OPC) to link to a LabVIEW program. This is a fundamental step providing another linkage between Experion and a MATLAB program through OPC in the future. The Pilot Plant Experion system has been extensively investigated in both hardware and software. By gaining an in-depth understanding of the system it was possible to identify the current problems regarding the plant and devise practical solutions for them. Numerous issues were resolved both physically and in the code. To prevent new issues from occurring, multiple interlocks have been designed, implemented and tested. Additionally the system’s code has also undergone restructuring, mainly in the form of removing redundant code. New sensors and actuators have also been installed and integrated into the system. Through the comprehensive research and development that was undertaken over the course of this thesis, it has become apparent that there is a vast range of projects and opportunities that can build upon this knowledge base and continue to improve the Murdoch University Pilot Plant and ultimately the Instrumentation and Control Engineering degree.

Human error has been a key factor in grounding- and collision incidents in the past and continues to present a challenge to the maritime industry in the present day. The feasibility of a pilot framework for Bridge Resource Management (BRM) training lies at the heart of this study, its objective being to gauge the possibility of the construction of such a model. The result is thought to open up for further research and highlight the most relevant and effective BRM tools that can be used, by the bridge team, to prevent collision and grounding. The study was carried out in two stages. Firstly, four key personnel within the shipping industry were interviewed. These respondents were tasked with prioritising what they regarded as the most effective BRM tools. Secondly, the effectiveness of these tools was tested on marine incident cases. A document analysis was carried out on six collision and grounding cases, as investigated by the Marine Accident Investigation Branch (MAIB). The majority of the respondents were in agreement regarding which three BRM tools they regarded as the most relevant and effective. The result from the interviews was repeated in the result from the document analysis. The conclusions that were drawn are that: it is possible to construct a pilot framework for BRM training and it is also possible to measure the effectiveness of the BRM tools. Additionally, suggestions for further research that arose from this thesis pertain to the study of the relationship between different BRM tools.

The Brazilian air transportation, also known as commercial air transportation, has been object of remarkable changes in the past 30 years. One of the main points of these changes results from the introduction of new technologies in the aircrafts cockpits, resumed after its automation in the expression glasscockpit . These technologies represent substantial changes on the pilot activity. The actual study focused on the research of the pilot social representation, trying to identify the probable effect of new technologies on the representation that pilots elaborate about their professional activity. It was used as a starting point for the carrying out of this project the Theory of Social Representations. To carry out this project, 216 subjects, pilots, divided in three categories by a time variable, a group was compiled by youths with less than ten years of activity; other pilots, developing the activity between 10 and 20 years and, finally, professionals with more than 20 years in activity, they participate of an empirical research. The social representation of the pilot, the professional experiences and the aviation changes perception were the axis investigated. The results allow us to suppose that general changes due to the using of new technologies are positive, that the subjects worries seem to judge other changes and that less experienced pilots offer excessive confidence to technology as safety manager.

A representação social do piloto, as práticas profissionais e a percepção das transformações na aviação foram os eixos investigados. Os resultados permitem supor que as transformações gerais por conta da tecnologia são positivas, que as preocupações dos sujeitos parecem julgar outras transformações e que os pilotos menos experientes oferecem confiança excessiva à tecnologia como gestora da segurança.

Streszczenie:

Safety in complex work environments is often an area of focus in the research community. Aviation is a multi-faceted field, but it remains one of the safest work environments in the world. For instance, despite passenger numbers increasing worldwide over many decades, the year 2013, when 3.1 billion passengers flew worldwide, is the safest year on record for aviation (Aviation Safety Network, 2017). That year resulted in only 29 fatal crashes and 265 deaths – one per 11,501,886 miles flown. Despite these impressive statistics, every disaster affects the lives of many people and attracts the attention of the general public, who demand answers. As a result, aviation has continually sought to discover new methods for increasing safety. Early in the twentieth century, when aviation was developing as an industry, accidents were decreasing steadily due to technical improvements, such as advances in aircraft structures and materials, aerodynamics, and systems. In the 1970s, as safety improvements plateaued, the link between human error and aviation accidents became increasingly apparent. This was emphasised in 1977, when 583 people were killed in a collision between two aircraft on a runway in Tenerife. The collision was found to have been the result of poor decision-making and miscommunication by pilots. In the aftermath of the crash, the Royal Dutch Airline KLM (the main protagonist) created the KLM Human Factors Programme. Recognising the part humans play in safety, the purpose of this programme is to improve communication and resource management skills among pilots. In an ongoing effort to improve safety, the aviation industry continues to develop more initiatives based on “human in the cockpit” principles, both in design and in operation. One such strategy is the Line Operations Safety Audit (LOSA). Developed in the 1990s at the University of Texas, the goal of this initiative is to audit pilots’ behaviour during normal flight operations for the purpose of improving air safety. It is a methodology whereby observers sit in aircraft flight decks and unobtrusively monitor pilots’ communications, the threats they face, the errors they make, and how they mitigate these threats and errors. In other words, it is a snapshot of pilot responses to factors impacting safety in normal flights as opposed to a line check by an examiner, where pilots display “angel behaviour” during a flight assessment. Many commercial airlines now use LOSA in their multi-crew operations in order to identify any patterns in behaviour, communication or systems that may need to be changed to improve aviation safety. Whilst commercial aviation generally has a very good safety record, single-pilot operations lag considerably behind, therefore safety in single-pilot operations needs to be further investigated. Past initiatives for improving the safety of single-pilot operations have been less than successful, so new and innovative approaches must be considered. To date, LOSA has not been used in single-pilot operations, and no studies have investigated its applicability in the single-pilot context. This thesis examines the possibility of adapting the LOSA methodology into the single pilot environment, a variation here known as LOSA:SP. The first study conducted for this thesis by the author, implemented the LOSA methodology with pilots working for an emergency services company in Australia. It was clear from the study that the threat and error conceptual framework and observational methodology that are key elements of LOSA were applicable to these single-pilot operations. The results initially supported the view that with minor modifications, the LOSA methodology may be applied to single-pilot operations. In the LOSA:SP study, when pilots were observed to talk aloud during flight, it was referred to as verbalisation. During the study, it became apparent that some pilots used verbalisation as a method for improving their cognitive performance. Further, this verbalisation actually assisted the unobtrusive observers during the LOSA:SP study because it made available to the observers the process of how the pilots’ reached certain decisons. This is significant because two-pilot crews normally discuss their reasoning and decision-making out loud to each other, but this form of verbalisation does not always occur in single-pilot flights. For verbalisation to be viable in the single-pilot environment, limitations must be considered, including safety. A further study was conducted using transcripts and data from a current research project exploring verbalisation in multi-crew operations under simulator conditions. The research aim was to examine the viability of verbalising during different workload phases of flight, such as taxi, take-off, and landing. A method consisting of both concurrent and retrospective verbalisation was used to examine a captain and first officer (second in command) over two simulated flights. The pilots were asked to verbalise during simulated scenarios, and each simulation was audio-visually recorded. Soon afterwards, the pilots were shown these recordings in a separate debriefing room and asked to comment on their performance. Special attention was paid to verbalisations made during three different degrees of workload: low, medium, and high. A total of five overall themes emerged from this study. The most significant were that pilots said that verbalisations during periods of low and medium workload assisted them with their cognitive processes, but verbalisations during periods of high workload were minimal and were perceived by pilots as interfering with their tasks. This second study suggested two findings: that safety could be compromised if pilots were forced to verbalise under periods of high workload and that retrospective verbalisation (or debriefings) were extremely helpful in gaining context supporting thoughts and actions that allowed participants to realise and learn from mistakes and good practices. To determine whether these findings were applicable to SPO, a third study, in the form of a literature review and thematic analysis of LinkedIn data and Focus Group transcripts was undertaken. This study identified that verbalisation is used by many single pilots and flight instructors as a means of enhancing cognitive ability. Yet mulit-crew operators had significantly different views, believing that verbalisation was less useful. Additionally, the literature review uncovered many other applications of verbalisation in other transport and safety conscious industries. The LinkedIn data and Focus Group correspondents also gave opinions on the viability of the LOSA methodology for single pilot operations resulting in a wide variety of discussion. In discussing these results in relation to the application of LOSA in a single-pilot environment, several considerations are suggested in this thesis. One is that the value of verbalisation depends on the situation in which it is used. Another important factor to consider is the familiarity pilots have with verbalisation and how comfortable they are verbalising. Requiring a pilot to verbalise for the purpose of a LOSA:SP may reduce pilot performance in high workload scenarios (with obvious safety consequences). This limits complete transferability of the LOSA methodology to single-pilot operations, where having access to pilot thought processes is fundamental. However, retrospective debriefing may be a useful technique for regaining some of the merits of LOSA:SP as a safety intervention. The willingness of a company to introduce a LOSA seems to suggest an increased awareness of safety, which can only be positive and many respondents found success in adaptations of the methodology to certain routes or conditions. Even without cross-talk between crews, LOSA:SP has sufficient merit for industry to be interested in replicating it.

Thesis advisor: Thomas M. Crea
Child sexual abuse is a major public health problem in the United States, but identifying risk, especially in young children with suspicion of abuse, poses many challenges. The aim of this study is to understand how clinicians judge the possible presence of sexual abuse in children where serious suspicion exists but without substantiated abuse. This study used data from randomly selected sexual abuse and trauma evaluations of preschool and school-aged children presenting to Boston Children’s Hospital (BCH) Outpatient Child Protection Program between 2000-2007 (N=100) to examine the association between child and family risk factors and level of clinician concern regarding likelihood of child sexual abuse. Multi-nomial logistic regression analysis was used to examine the relationship between child and family risk factors and level of clinician concern regarding suspicion of abuse, moderated by child’s gender and age. Results indicated that a child’s disclosure and trauma presentation were the key factors that clinicians considered within the higher level of clinician concern regarding likelihood of sexual abuse. Implications for future research and clinical practice include attention to methodology research to assist with the development and validation of assessments for evaluation of risk in complex cases of suspicion of sexual abuse that can be offered in clinical setting, without sole reliance on the child’s ability to disclose in order to access help. Additionally, it is essential that research focuses on the development of clinical models to help with clinical decision making protocols in ambiguous cases of sexual abuse with children who may not be in a position to disclose, but serious concerns have been raised, with focus on increasing their safety. The findings in this research strongly suggest that it is essential to continue to focus on assisting children who present with suspicion of sexual abuse in complex cases that do not fit neatly into our current forensic and child protective services systems. This is especially necessary with the most vulnerable children where disclosure is unlikely, but clinical evaluations can yield recommendations that maximize efforts at increasing safety, child mental health, and family cohesion, and build on strengths while simultaneously accounting for risks

Streszczenie:

In type 2 diabetes the concentration of glucose in the blood is increased, and tissues like fat and musclebecome less sensitive to insulin. These two phenomena are interrelated, but since the glucose-insulininterplay is highly complex, many aspects are still not understood. Here, a model-based approachmight help. Nevertheless, also a model-based approach has a limited impact, unless models for thesub-systems can be combined into a model for the whole-body regulation. Such a multi-level,module-based model is referred to as a hierarchical model, and this thesis is a proof-of-principle studyfor the future development of such models.

We have extended one of the best available models for the whole-body regulations, to include azoomable module for the fat tissue. The first step was to implement the whole-body model in thesoftware MathModelica, which support hierarchical modeling. Second, the originally mergedinsulin-responding module was sub-divided, so that a fat tissue was singled out. Third, a model for theinput-output profile for the fat tissue was developed by combining mechanistic knowledge withexisting and novel data from human fat cells. Finally, this detailed model was fitted to the profile of theoriginal fat model, and inserted in the whole-body model, with negligible effect on the whole-bodysimulations.

The resulting model has the ability to translate mechanistically oriented simulations on the biochemicallevel, which is the level were drugs act, to the whole-body level, which is of clinical interest. This is aquantum leap forward for modeling, and understanding, glucose homeostasis and type 2 diabetes.

Pilot spatial disorientation (SD) is a significant cause of incidents and fatal accidents in aviation. The pilot is susceptible to SD especially in low visibility when the visual system is deprived of information from outside the cockpit. This thesis presents the notion of visual flow displays as enhancement of symbology on flight displays primarily in low visibility for improved support of the pilot’s spatial orientation (SO) and control actions. In Studies I and II, synthetic visual flow of forward ego-motion was presented on displays and postural responses were used as measures of display effectiveness in determining SO. The visual flow significantly affected SO, and although the increased stimulation of the visual periphery from a width of 45° to about 105° increased the effects there was no further effect at a width of about 150° (Studies I and II). Studies I and II also showed that omitting 20°- or 30°-wide central fields of view from the visual flow either reduced or not reduced the effects. Further, although inconclusive, Study II may indicate that horizon symbology in central visual field may enhance the effects of peripheral visual flow. The appropriate integration of peripheral visual flow with the head-up display symbology of the Gripen aircraft was presented. Acceleration in a human centrifuge was used in Study III to investigate the effects of synthetic visual flow on the primarily vestibular-dependent somatogravic illusion of pitch-up. Two experiments revealed a reduced illusion with the visual flow. The results of Experiment 2 showed the visual flow scene not only reduced the illusion compared with a darkness condition but also compared with the visual scene without visual flow. Thus, similar to the main findings of Studies I and II, synthetic visual flow can significantly affect SO and supports the visually dependent SO system in an essential manner.

Deciding how to construct a training programme or a training exercise, and especially what and how training media and methods should be selected to deliver effective and efficient training is an ongoing endeavour that preoccupies training analysts and designers alike. There are many interactions and dependencies that one has to take into consideration when making decisions, about cost, safety, or interactions between various components of a training system (e.g. between various types of media; between media and methods; between media, methods and trainees) to produce the desired outcome. The focus of this PhD research is to develop an understanding of the challenges faced by decision-makers within the military fast-jet training domain in constructing the training and, further, to develop solutions that support the decision-making effort. A significant challenge faced by decision-makers in constructing training programmes, identified through this research, is the ever increasing amount of information that they need to have at their disposal to enable fully informed decision-making and the lack of methods and tools to facilitate the management and analysis of this information. This research specifically investigated the problem of media selection to construct the training and developed a series of concept solutions to support differentiation between training media, assessment of trainees previous experiences, management of TNA outputs, selection of instructional methods and understanding of the cognitive relationship between media, method and trainee. The thesis firstly introduces the problem to be addressed; the research context and research questions set to be answered. This research, sponsored by Engineering and Physical Science Research Council (EPSERC) and BAE Systems, is preceded by another BAE Systems funded research project (the Training Optimisation Case Study), which provided the background for the work presented in this thesis. Secondly, it reviews the literature relevant to the subject matter to understand the current state of knowledge in the area of: UK RAF training programmes construction and training media selection; assessment of competencies; impact of media and method on learning; development of decision making support systems; and construction and management of knowledge. The main part of the work presented in this thesis is the development of a series of support solutions to aid the decision-making process of construction of UK fast-jet pilot training. These include: TNA output Analysis (ToA) tool; Trainee Contextual Proficiency Profile (TCPP) tool; Training Media Classification Framework; models that map the cognitive relationship between media, method and trainee, and a unified Framework of Selection of Instructional Process alongside a novel approach towards training media selection. This research work was initially scoped through an exploratory study (a case study) into the domain area, followed by requirements elicitation. This part of research helped at identifying the issues within the problem area and in defining the research questions. The TCPP and ToA were verified through two case studies and presented alongside the rest of the research to the customer (BAE Systems) that gave positive feedback on the research outcomes.

The aim of this project was to evaluate the Contingencies for Learning Academic and Social Skills (CLASS) programme in four New Zealand classrooms. Four students with antisocial behaviour were nominated by their teachers to take part in an intervention that included differential attention, increased praise and rewards. Direct observations were made of compliance to teacher instructions, on-task behaviour, teacher praise and teacher instructions. Results indicated that on-task behaviour and compliance to teacher instructions increased during the intervention phase and was maintained during the follow-up. Teachers were also able to increase their rate of praise per hour during the intervention phase and their praise rate remained greater at follow-up than during the baseline phase. In the absence of pre-service and in-service behaviour management training for teachers, the CLASS programme proved to be a useful tool to assist teachers who have to work with children with high rates of antisocial behaviour.

A model for the prediction of color release from a pilot distribution system was created in 2003 by Imran. This model allows prediction of the release of color from aged cast iron and galvanized steel pipes as a function of water quality and hydraulic residence time. Color was used as a surrogate measurement for iron, which exhibited a strong linear correlation. An anomaly of this model was an absence of a term to account for pH, due to the influent water being well stabilized. A new study was completed to evaluate the effectiveness of corrosion inhibitors against traditional adjustment. Two control lines were supplied with nearly same water qualities, one at pH close to pHs and one at pH well above pHs. The resulting data showed that effluent iron values were typically greater in the line with lower pH. The non-linear color model by Imran shows good agreement when the LSI was largely positive, but underpredicted the color release from the lower LSI line. A modification to the Larson Ratio proposed by Imran was able to give a reasonable agreement to the data at lower LSI values. LSI showed no definite relation to iron release, although a visual trend of higher LSI mitigating iron release can be seen. An iron flux model was also developed on the same pilot system by Mutoti. This model was based on a steady state mass balance of iron in a pipe. The constants for the model were empirically derived from experiments at different hydraulic conditions with a constant water quality. Experiments were assumed to reach steady state at 3 pipe volumes due to the near constant effluent turbidity achieved at this point. The model proposes that the iron flux under laminar flow conditions is constant, while the iron flux is linearly related to the Reynolds Number under turbulent conditions. This model incorporates the color release models developed by Imran to calculate flux values from different water qualities. A limited number of experiments were performed in the current study using desalinated and ground water sources at Reynolds Numbers ranging from 50 to 200. The results of these limited experiments showed that the iron flux for cast iron pipe was approximately one-half of the predicted values from Mutoti. This discrepancy may be caused by the more extensive flushing of the pipes performed on the current experiments which allowed attainment of a true steady state. Model changes were proposed to distinguish between near stagnant flow and the upper laminar region, with the upper laminar region showing a slight linear increase. Predictions using the galvanized flux model were not accurate due to an inferior color release model that was developed for galvanized pipes. The model exhibits a high dependence on sulfate concentrations, but concentrations of sulfates in the current experiments were low. This led to low predicted flux values when the actual data showed otherwise. A new galvanized model was developed from a combination of data from the original and current experiments. The predicted flux values using the new model showed great improvement over the old model, but the new model database was limited and the resulting model was not able to be independently tested.

The master thesis consists of a theoretical part and a practical part. In the theoretical part jet-grouting technology is described briefly. Mechanical properties of jet-grouted piles were characterized. Various estimation methods of ultimate pile bearing capacity are described in this thesis – analytical calculation of ultimate bearing capacity for bored piles and estimation of ultimate pile bearing capacity by analysis of load-displacement curve defined by CHIN (1970; 1972). Load transfer method for piles and hyperbolic load-transfer curve are introduced. As a part of the load-trasfer method analysis, a method of estimating ultimate pile shaft friction called beta method is defined. In the practical part were evaluated several static load tests of jet-grouted piles and were constructed their load-displacemnt curves. Then reverse analysis of the results from static load tests was performed using load-transfer method. Then ultimate pile bearing capacity was estimated using analytical calculation of pile bearing capacity for bored piles and using analysis of load-displacement curve with method by CHIN (1970; 1972). By evaluation of load transfer method and beta method ultimate shaft resistence for each pile was estimated. Results and load-displacement curves were compared.

Purpose: The purpose of this pilot study was to describe situation awareness (SA) among licensed practical nurses (LPNs) working in direct patient care. Specific Aims: The specific aims for this study are 1) to examine SA scores, as measured by the Situation Awareness Global Assessment Technique (SAGAT), in LPNs working in direct patient care and compare to published data on SA in registered nurses (RNs), 2) to examine the relationship between SA scores and years of LPN experience, 3) to examine differences in SA scores by type of workplace setting and 4) to describe the relationship between levels of satisfaction with simulation, as measured by the Satisfaction with Simulation Experience Scale (SSES) and SA scores among LPNs. Framework: Situation Awareness Theory, as described by Endsley, was used as the framework for this study. Design: A cross-sectional, descriptive design using the Situation Awareness Global Assessment Technique was used to gather data from a convenience sample of LPNs. Results: LPNs (N=24) participated in the study and achieved an average SAGAT score of 72.6%. There were no differences in scores between those LPNs enrolled in an RN program and those who were not enrolled. Individual scores on the SAGAT were comparable or better than scores in a similar study of RNs. Conclusion: LPNs in this study demonstrated adequate situation awareness. Key Words: Situation awareness, licensed practical nurse, patient deterioration, clinical simulation
