A Horizontal Axis Wind Turbine (HAWT) experiences imbalanced loads when it operates under yaw loads. For each blade element of the aerodynamically imbalanced rotor, not only is the angle of attack unsteady, but also the corresponding incident velocity, a fact usually unfairly ignored. For the unsteady angle of attack, a pitch oscillating airfoil has been studied experimentally and numerically when 3.5×10⁴<Re<10⁵. For small wind tunnel airfoils, Particle Image Velocimetry (PIV) was utilized to determine the aerodynamic loads and the pressure field where other measurement techniques are either intrusive or very challenging. For dynamic airfoils in highly separated flow fields, i.e., deep dynamic stall phenomena, loads were calculated successfully based on the control-volume approach by exploring ways to reduce the level of uncertainties in particular for drag estimation. Consecutive high resolution PIV velocity fields revealed that increasing the reduced frequency was followed by an enriched vortex growth time and phase delay as well as a reduced number of vortices during upstroke motion. Moreover, the locations of the vortices after separation were influenced by each other. Laminar separation bubble height also showed a reducing trend as the reduced frequency increased. The nature of the vortex sheet vortices before stall were explored in two Reynolds numbers, with and without laminar separation bubbles, at low angles of attack. For all cases, a vortex sheet was the result of random vortex sheding while a longer vortex sheet was more favorable for lift augmentation. A wake study and averaged drag calculation at low angles of attack were also performed with Laser Doppler Anemometry (LDA) for Re=10⁵. For the unsteady incident velocity, longitudinal freestream oscillations have been studied numerically, since experimental study of an unsteady freestream is challenging. In this regard, the streamwise freestream velocity and pitch angle of incidence oscillated with the same frequency in a wide range of phase differences. Changing the phase difference caused variation of the results, including significantly augmented and dramatically damped dynamic stall loads, both increasing and decreasing trends for vortex growth time during phase increase and shifted location of the maximum loads. The results showed strong dependency on the velocity and acceleration of the freestream during dynamic stall and the dynamic stall characteristics differed significantly from those of the steady freestream states. The results also demonstrated consistent trends regardless of the airfoil shape and the Reynolds number while Re=10⁵ and 10⁶. The vortex study presented here not only provides information about the unsteady aerodynamic forces, but also knowledge regarding airfoil noise generation and distributed flow for downstream objects beyond wind turbine applications.

This research examined leadership in difficult situations using phenomenological and critical incident analyses of 14 interviews with respected leaders. Leadership in difficult situations was examined as a personal experience consistent with the perspective of counselling psychology. The phenomenological analysis has produced four voices. The first voice captures the participants' description of leadership as a paradox of personal and situational dynamics. The second voice forms an uncommon elucidation of the lived experience of leadership in difficult situations. The participants are seen to be striving in a resilient manner characterized by a sense of acceptance and authenticity. The third and fourth voices describe the means by which the participants are effective in difficult situations. The third voice captures the intra-personal process of resonance, personal and social awareness, personal supports, mastery of the issues, and the capacity to generate remarkable outcomes. The fourth phenomenological voice captures the participant's active engagement in connecting with people, shaping the work context and leading collaboration to develop a successful process. Five categories have been produced by the Critical Incident Technique, which examined what helps and what hinders in the experience of leadership through difficult situations. The five categories are: being experienced, principled and self-aware; having personal supports and influences; being interested and skilled in connecting with people; being both energetic and able to withdraw appropriately; finally, actively cultivating their perspective or vision. These five categories indicate the capacity of the participants for diverse means of participation in difficult situations. Results are discussed in terms of implications for research and practice.

Disruptions can cause projects to fail. Within the project management literature, approaches to managing disruptions consist of uncertainty, risk, opportunity, change, and crisis management. These approaches focus on developing strategies to manage perceived threats and also work towards predicting risk, therefore, reducing vulnerability. This vulnerability-reduction only focus is limiting because it takes the focus away from the development of a general capacity for readiness and for responding to uncertain situations. A resiliency approach enables a simultaneous focus on vulnerability reduction, readiness and response and thus ensures recovery. Given the context and discipline specific nature of the resilience concept, and the little or no attention in projects, this thesis conceptualises resilience in projects. This conceptualisation is to enable the identification of factors to consider and indicators to ensure overall project recovery, through the identification of dimensions and antecedents of resilience respectively. The aim of this study therefore, is to develop a framework to conceptualise resilience in projects. To achieve this aim, three case studies, namely; building, civil engineering and engineering construction projects were investigated. Within each case study, the critical incident technique was employed to identify disruptions and their management through direct observations of human activities, narration of critical incidents and review of documents on disruption. Following this, a comparative analysis and synthesis of the case studies was carried out and findings revealed definition, dimensions, antecedents and consequences of resilience in projects. Specifically, resilience in projects is defined as; the capability of a project to respond to, prepare for and reduce the impact of disruption caused by the drifting environment and project complexity. The dimensions of resilience are; proactivity, coping ability, flexibility and persistence. Proactivity can be defined as an anticipatory capability that the project takes to influence their endeavours whilst coping ability can be defined as the capability to manage and deal with stress caused by disruptions within the projects. Furthermore, flexibility can be defined as the capability of a project to manage disruption by allowing change but ultimately making sure that the aim is maintained and persistence is the capability to continue despite difficult situations. Several antecedents of these dimensions of resilience are identified. For proactivity these include contract, training, monitoring, contingency and experience. For coping ability these include the contract, training, contingency and experience. For flexibility these include open-mindedness, planning, continual monitoring and continual identification of ideas and for persistence these include continual monitoring, planning and negotiation. Also, the consequence of resilience in projects is recovery through response, readiness and vulnerability reduction. This conceptualisation of resilience is then synthesised into a validated framework for resilience in projects. Theoretically, this research provides definition, dimensions, antecedents and consequence for resilience in projects and a theoretical starting point for the concept of resilience in projects. The significance of this research to practice is the identification and development of a more holistic perspective of managing disruptions in projects through the identified dimensions, antecedents and consequences. These dimensions, antecedents and consequences provide clarity for the roles of project managers and team members in managing disruptions and thus, expand the eleventh knowledge area; project risk management, of the Project Management Book of Knowledge (PMBOK). In addition, the dimensions, antecedents and consequences of resilience in projects contribute to the curriculum development in project management and thus, provide factors and indicators that project managers require in managing disruptions.

The marketing plan's implementation schedule provides a roadmap for accomplishing a firm's stated marketing objectives. For over three decades researchers have investigated planning's link to firm performance. The consensus has been that they do improve performance although there is little empirical evidence to suggest how implementation of those plans is related. Environmental turbulence, new information and failed implementation cause firms to act outside of the planning framework. Improvisation is the contemporaneous creation and execution of an action. The extent to which firms act improvisationally has been studied, but to date there has been no empirical investigation that exposes the different types of post plan improvisations of strategic marketing plans that exist. This dissertation attempts to identify the different types of post plan improvisations (PPI) used in marketing. Using the Critical Incident Technique, 384 incidents of PPI were gathered from marketing planners and then used to create categories and systematically classify each incident. Four primary categories of causes of deviations, six categories of deviations and four categories of outcomes emerged from the data. The results provide a foundation for a theoretical model of the types of post plan improvisations in practice. This will allow further research into contextual differences that could help managers decide when to improvise and when to follow their plan. Further, by exposing the useful application of the CIT method in a new field, additional researchers might begin to use the technique to update and more deeply understand other marketing phenomenon. / Adviser: David M.

This thesis presents an overview of the risks emergencies caused by natural factors. It deals with their causes, potential consequences, which may endanger the health, lives and property of the citizens of the Slovak Republic, and ultimately the environment. The aim of my thesis is to analyze the potential risks for the population resulting from emergencies caused by natural effects and compare them to the risks listed with the relevant authorities. Also, the order of presentation of the results obtained suggest risk register. The acquisition of knowledge I have chosen a method of study of existing legislation, technical publications in the field of crisis management and the protection of people and documentation of state administration, the risks associated with emergencies caused by natural influences, led by the relevant authorities. The theoretical part of the work is in its initial section focuses on clarifying key concepts, namely risk, threat, impact and natural incident. In addition they also illuminates other words such as, emergency and emergency situation, essential for understanding the context of their work. Explains the importance of a specific force in relation to the induction of incidents which cause is natural, forces of nature, without human intervention. Legislation is based on the selection of existing legal norms Slovak Republic. In the following text to become a master thesis deals with a description of the geographical, hydrological and meteorological conditions alone Slovak Republic as well as natural conditions Košice and Prešov region. Draws attention to the particular circumstances of the two regions, resulting in the definition of the specific risks of emergencies caused by natural factors. So I filled the objectives specified in the thesis, I decided on the basis of geographical, hydrological and meteorological conditions in the Prešov and Košice regions described in Chapter I., process risks existing emergency caused by natural influences, which is repeated every year with different degrees of damage, and flood. The practical part has specifically describe the flood - its causes, risks and possible consequences in selected areas of Kosice and Presov region. I discuss my findings detected by the method of qualitative research conducted standardized interview with experts on civil protection. On the basis of interviews, I conclude that the hypothesis of "governmental entities in the defined area of Košice and Prešov regions have sufficient risk assessment of selected emergencies caused by natural effects" was confirmed and the authorities are trying as much as possible to eliminate the risk of flooding. Representatives of municipalities have learned from extensive flooding in 2010, when there were huge losses. Since that time there has been a reassessment of buildings in flood zones, was developed many plans and projects, consider the new risks and a greater range of the governed territory. Currently being developed flood hazard maps and flood risk maps for areas managed by the government, which significantly helps make for the best possible identification of risks from floods, mapped most vulnerable areas and thus become the basis for developing measures for flood navhodnejších only managed a territory of Košice of Prešov in Slovakia. However, the essence of eliminating the risk of flooding to the lowest possible level in Košice and Prešov regions remains, according to the representatives of the government, naustála update streams, effective communication and collaboration with administrators of watercourses and always ready state administration bodies to the very existence and the related consequences of floods .
