Background: The inclusion of women in the armed Forces is becoming increasingly commonplace, with figures currently standing at 10.2% of the regular Forces in the United Kingdom (UK). This is set to rise with the introduction of the new Ground Close Combat (GCC) ruling which came in earlier this year (2017), allowing women to serve on the frontline with their male colleagues. However, alongside these changes, women already face stressors and exposure to combat in the Forces that potentially contribute to difficult transitions back into everyday life when leaving the military environment. The aim of this study was therefore to engage with and explore the experiences of female veterans psychological health and wellbeing as they transition from the Forces into civilian life, understanding the different processes they encounter as they transition. Methodology: Six female veterans who fit the inclusion criteria were recruited for the study. In this qualitative study, semi-structured, one-to-one, in-depth interviews were conducted and analysed in accordance with Charmaz's (2006) Constructivist Grounded Theory (CGT) guidelines. This iterative and inductive analytical process was utilised to construct an understanding of the participant's experiences and understandings of their transition. Findings: Concurrent with the CGT approach, nine theoretical categories developed from the analysis of the interviews, including role reversal, sexism and loss. These contributed to the development of a transition model, representing an interaction between the military environment, no mans land and the civilian environment. Findings indicate that experiences of transitioning faced by female veterans are complex, and involve gender-related issues. The findings also suggest that problems with mental health such as Post-Traumatic Stress Disorder are common, and are heightened by additional stressors specific to women's experience in the military and civilian environments. Discussion and Conclusion: These findings suggest that female veterans health and psychological wellbeing experiences in the military are parallel to those they experience in civilian life. Consistent with previous literature, the female veterans interviewed appear to have experienced their transitions differently to male counterparts, with additional stressors present throughout their transitions. These stressors contribute to the uncertainty of identity, stigma and a loss of military ways when transitioning back into a civilian society. Consequently, more services that are tailored to female military veterans, are proposed, in order to support the increasing number of female veterans that will present in the future. This has implications for therapeutic practice in counselling psychology, whereby a deeper understanding of the difficulties and challenges experienced by female veterans during transition into civilian life can inform therapeutic interventions and signposting to specific services tailored their needs.

A systematic approach of testing and validating transition models is developed and employed in testing of a recently developed transition model. The testing methodology uses efficient computational tools and a wide range of test cases. The computational tools include a boundary layer code, single zone Navier Stokes solver, and a multi-block Navier Stokes solver which uses MPI and is capable of handling complex geometries and moving grids. Test cases include simple flat plate experiments, cascade experiments, and unsteady wake/blade interaction experiments. The test cases are used to test the predicting capabilities of the transition model under various effects such as free stream turbulence intensity, Reynolds number variations, pressure gradient, flow separation, and unsteady wake/blade interaction. Using the above test cases and computational tools a method is developed to validate transition models. The transition model is first implemented in boundary layer code and tested for simple flat plate cases. Then the transition model is implemented in single zone Navier Stokes solver and tested for hysteresis effects for flat plate cases. Finally the transition model is implemented in multi zone Navier Stokes solver and tested for compressor and turbine cascade cases followed by unsteady wake/blade interaction experiments. Using the method developed a new correlation based transition model (Menter et al. 2004) which uses local variables is tested and validated. The new model predicted good results for high free stream turbulence and high Reynolds number cases. For low free stream turbulence and low Reynolds number cases, the results were satisfactory.

The conflict in Afghanistan which has predominated much of the first decade of the new millennium has resulted in the creation of a new generation of Canadian war veterans. This veteran culture will include Canadian military personnel who were either directly or indirectly involved in active peacekeeping duty during their careers. Some of these men and women choose retirement to pursue other interests or second careers in the civilian world. Others are facing involuntary early retirement due to permanent medical or combat-related stress factors, such as post traumatic stress disorder (PTSD). Medical release, in combination with age and socioeconomic circumstances can result in adjustment difficulties (Sweet, Stoler, Kelter, & Thurrell, 1989; Westwood, Black & McLean, 2002). A qualitative study of the experiences of ten Canadian soldiers in transition from military life to civilian education environments over a three-month period from November, 2011 to February, 2012 was carried out. The following themes emerged as major areas of discussion: transition issues, unanticipated transitions and non-events, camaraderie and the veteran identity, transferable skills, and support and resources. The transition model developed by Schlossberg and presented by Goodman, Schlossberg, and Anderson (2006) was used as a guiding theory to develop an understanding of the transition experience in reference to this new population of Canadian military veterans. Theories of cross-cultural transition were used as a framework for discussion. Recommendations for facilitating transition through education for Canadian soldiers are included. / Thesis (Master, Education) -- Queen's University, 2012-04-23 17:09:52.269

A major challenge in the design of turbomachinery components for aircraft gas turbine engines is high cycle fatigue failures due to flutter. Of particular concern is the subsonic/transonic stall flutter boundary which occurs at part speed near the stall line. At these operating conditions the incidence angle is large and the relative Mach number is high subsonic or transonic. Viscous effects dominate for high incidence angles. In order to predict the flutter phenomena, accurate calculation of the steady and unsteady aerodynamic loading on the turbomachinery airfoils is necessary. The development of unsteady aerodynamic models to predict the unsteady forces and moments acting on turbomachine airfoils is an area of fundamental research interest. Unsteady Reynolds Averaged Navier-Stokes (RANS) models have been developed to accurately account for viscous effects. For these Reynolds averaged equations turbulence models are needed for the Reynolds stress terms. A transition model is also necessary. The transition onset location is determined by a transition onset model or specified at the suction peak. Usually algebraic, one or two-equation or Reynolds stress turbulence models are used. Since the Reynolds numbers in turbomachinery are large enough to guarantee the flow is turbulent, suitable transition and turbulence models are crucial for accurate prediction of steady and unsteady separated flow. The viscous flow solution of compressor airfoils at off-design conditions is challenging due to flow separation and transition to turbulent flow within separation bubbles. Additional complexity arises when the airfoils are vibrating as is encountered in stall flutter. In this investigation calculations are made of a transonic compressor airfoil in steady flow and with the airfoils oscillating in a pitching motion about the mid-chord at 0° and 10° of chordal incidence angle, and correlated with experiments conducted in the NASA GRC Transonic Flutter Cascade. To model the influence of flow transition on the steady and unsteady aerodynamic flow characteristics, the Solomon, Walker, and Gostelow (SWG) transition model is utilized. The one-equation Spalart-Allmaras model is used to model turbulence. Different transition onset models including fixed onset are implemented and compared for the two incidence angle cases. At each incidence angle, the computational model is compared to the experimental data for the steady flow case and also for pitching oscillation at a reduced frequency of 0.4. The 10° incidence angle case has flow separation over front 40% of the airfoil chord. The operating conditions considered are an inlet Mach number of 0.5 and a Reynolds number of 0.9 Million.

The grid of the future will be more decentralized due to the significant increase in distributed generation, and microgrids. In addition, due to the proliferation of large-scale intermittent wind power, the randomness in power system state will increase to unprecedented levels. This dissertation proposes a new state transition model for power system forecasting-aided state estimation, which aims at capturing the increasing stochastic nature in the states of the grid of the future. The proposed state forecasting model is based on time-series modeling of filtered system states and it takes spatial correlation among the states into account. Once the states with high spatial correlation are identified, the time-series models are developed to capture the dependency of voltages and angles in time and among each other. The temporal correlation in power system states (i.e. voltage angles and magnitudes) is modeled by using autoregression, while the spatial correlation among the system states (i.e. voltage angles) is modeled using vector autoregression. Simulation results show significant improvement in power system state forecasting accuracy especially in presence of distributed generation and microgrids. / Ph. D.

Remote work was already an ongoing trend amongst software developers, but the sudden and unexpected occurrence of the COVID-19 pandemic made it normal due to the obligations for many people to stay and work from home.  To go from the safeness of the work office with an always-working Internet connection and colleagues around to exchange ideas with, to working from home can be a big change from one day to another. Without a good structure or adjustment from the organization, this would lead to a decrease in good work results, communication issues and difficulty for managers to keep track of what is done and by whom. To facilitate this, commonly used methods are the Agile Methodologies. Beck et al. (2001) make it significant in the 12 principles of Agile that the most efficient and effective method of conveying information is by face-to-face conversation for the best results. Investigating the work that was done face-to-face previous to the pandemic but is now done remotely from home within agile teams is therefore of much relevance today. This thesis was intended to investigate and learn how the use of agile methodologies has facilitated the sudden transition to remote work from home and affected the aspects of communication and work results within an agile development team. The study was conducted using the qualitative method with interviews consisting of seven open-response and two closed-response questions with respondents in agile teams from a software development company in Sweden. The analysis was made thematically in relation to Bridge’s Transition Model, and in relation to previous research. The study identified three themes to answer the research question based on the theoretical framework; The Change, Communication and Work Results. The results of the study show that the use of Agile Methodologies indeed has simplified the sudden transition to remote work from home, which was called The Change, as many of the agile practices already were done online previous to the pandemic. The study has also concluded that the use of Agile Methodologies has positively affected the aspects of communication and work results in an agile team, as it was found that forms of communication became more creative as they occurred more frequently while working from home, and it ultimately led to more valuable end-results. / Distansarbete var redan en pågående trend bland mjukvaruutvecklare, men den plötsliga och oväntade förekomsten av COVID-19-pandemin gjorde det normalt på grund av restriktionerna för många människor att arbeta hemifrån. Att gå från arbetskontorets säkerhet med en alltid fungerande internetuppkoppling och kollegor runt om för att diskutera idéer med, till att arbeta hemifrån kan vara en stor förändring från en dag till en annan. Utan en bra struktur eller anpassning från organisationen skulle detta leda till en minskning av goda arbetsresultat, dålig kommunikation och svårigheter för chefer att hålla reda på vad som görs och av vem. Vanliga metoder att använda för att underlätta detta är de agila metoderna. Beck et al. (2001) gör det tydligt i de 12 principerna för Agile att den mest effektiva metoden för att förmedla information i ett projekt är genom konversationer face to face, för bästa resultat. Att undersöka det arbete som innan pandemin gjordes face to face men nu görs på distans hemifrån inom agila team är därför av stor relevans idag. Denna studie var avsedd att undersöka och få kunskap om hur användningen av agila metoder har underlättat den plötsliga övergången till distansarbete hemifrån och påverkat aspekterna av kommunikation och arbetsresultat inom ett agilt utvecklingsteam. Studien genomfördes med hjälp av den kvalitativa metoden med intervjuer bestående av sju öppna frågor och två slutna svarfrågor med respondenter i agila team från ett mjukvaruutvecklingsföretag i Sverige. Analysen gjordes tematiskt i förhållande till Bridge’s Transition Model och i förhållande till tidigare forskning. Studien identifierade tre teman för att besvara forskningsfrågan utifrån det teoretiska ramverket; The Change, Communication och Work Results. Resultaten av studien visar att användningen av agila metoder har förenklat den plötsliga övergången till distansarbete hemifrån, eftersom många av de agila aktiviteterna redan gjordes online före pandemin. Studien har också dragit slutsatsen att användningen av agila metoder har påverkat aspekterna kommunikation och arbetsresultat positivt i ett agilt team, eftersom det visade sig att kommunikationsformer blev mer kreativa eftersom kommunikationen blev mer frekvent inträffande när de arbetade hemifrån, och det ledde slutligen till mer värdefulla slutresultat i projekt.
