The increasing use of electrical technologies within on-board (aircraft, road vehicle, train and ship) power systems is resulting in complex and highly dynamic networks in which energy storage devices have an important role to play, for example to resolve the instantaneous mismatch between load demand and power availability or to provide the flexibility to optimise overall performance. In this thesis, a multi-level controller for a super-capacitor based energy storage system (ESS) is designed, simulated, emulated and validated experimentally to show its effectiveness in smoothing load and managing state-of-charge of the energy storage system. This thesis first investigates the low level control of the dual-interleaved converter, particularly at light load where seven discontinuous conduction modes (DCMs) appear. A thorough analysis of these operating modes is given and validated by simulations and experiments. Based on the analysis, an inverse-model-based feed-forward current controller is implemented, offering a low level converter control interface which serves the high level supervisory controller within the energy storage system. Two supervisory control methods have been proposed in this thesis, both producing a super-capacitor current reference for the low level controller. The first supervisory control not only manages the energy within the ESS but also shields the primary power source from rapid load transients , which has been examined through an emulated ESS in the Intelligent Electrical Power Network Evaluation Facility (IEPNEF). A more advanced supervisory controller is then proposed which in addition to the benefits of the first control, regulates the rate-of-change in power that is drawn from the primary power source in the system. The proposed second control method is implemented within a real super-capacitor energy storage system in IEPNEF, with both simulation and experimental results successfully demonstrating and validating its operation.

Thesis (MBA)--Stellenbosch University, 2012. / Global Load Control (GLC) is a three-centre network with offices in Cape Town (South Africa), Brno (Czech Republic) and Istanbul (Turkey) that provides Weight&Balance services to its parent company, Lufthansa, and other airlines. The strategic direction of GLC includes growth in terms of expanding its customer base and target market as well as diversification into other services in the field of Ground Operations. Many of the airlines are re-evaluating their business model and service offering in order to increase their profitability and competitiveness in an industry that is going through a period of transformation. Historically, the industry has seen very small profit margins, which are expected to remain under immense pressure due to difficult macroeconomic conditions and strong competition. The human capital of GLC and the knowledge that exists within the organisation were identified as strategic assets during the strategy process. The shift towards a knowledge-driven economy and the importance of the ´knowledge worker´ has been acknowledged by scholars as well as the business community. Since then, ways to manage knowledge work and the productivity of the knowledge worker have received lots of attention. However, due to the contextual and subjective dimensions of knowledge, no blueprint exists for its successful implementation. The aim of the paper was to identify the contribution of knowledge management to the managerial process of positioning Global Load Control for strategic effectiveness. The research confirmed the growing recognition of the relevance of tacit knowledge as well as the importance of social capital to the organisational knowledge and intellectual capital, respectively. Important and relevant knowledge were found to be tacit and often lying in the action itself, which makes it difficult to codify and share with other employees. Strategic effectiveness of Global Load Control ultimately was found to be the ability to continuously support the customers in increasing their competitiveness, thereby creating strong ties with GLC as a business partner. This included the ability to maintain or increase its cost effectiveness and identifying new ways for the customer to gain an advantage. The research revealed that parts of the knowledge required for achieving this lie with the customer, which implied that they had to be integrated into the organisation´s knowledge base. Knowledge creation was found to be central in utilising GLC´s human capital to increase its intellectual capital. The importance of the social dimension, both internally and externally, was shown throughout the paper and found to be the linking element. Not ignoring the role and contribution of the physical infrastructure to the process of knowledge sharing, HR practices and policies play a vital role in creating enabling conditions for knowledge sharing and building of social capital, which are prerequisites for the creation of organisational knowledge and the development of GLC´s intellectual capital. Rather than being a stand-alone process, knowledge management is to be seen as a philosophy that provides valuable insights and gives guidance to the managerial processes of an organisation. When viewed as an integral part of the business, knowledge management can greatly contribute to positioning the organisation for strategic effectiveness. However, for this to happen, the subjective, dynamic and contextual nature of knowledge has to be acknowledged and the impact of factors such as organisational culture and learning styles be researched and integrated into the knowledge management strategy. The findings in this paper apply to the organisation researched only. However, it contributed to the body of knowledge by complementing the theoretical frameworks around knowledge management and intellectual capital with practical findings. It thus supports other organisations in identifying suitable research approaches and topics in their own organisation and allows academics to refine and question current concepts and thereby continue to develop our understanding of knowledge management.

The aim of this task is to find out the present role of the middle nursing management in the human resource management and also to suggest a new plan of graduate training in the terms of adaptation process. In the end it is necessary to analyse its asset from the nurse managers{\crq} point of view. Questionnaire technique of information gleaning was used for the survey. First survey body was formed by nurse managers. There were 25 questions in the questionnaire. A part of the questionnaire was a plan of graduate training. These graduates had to be educated as state registered nurses or with university degree, either Bachelor or Master. There were 18 closed questions and 7 half-open ones. Second survey body was formed by graduates of nursing colleges and universities. There were 8 questions in the questionnaire and there were 8 answers in each question. All the answers were used for assessment of level education dependence on motivational needs. There were four hypothesis in the survey which should confirm or disconfirm the interest of nurse managers in further education, its providing by hospital managements, the dependence of motivation needs on education level (only graduates) and evaluation of adaptation process provided by nurse managers. The first hypothesis confirmed that the nurse managers are interested in further education connected with human resource management. The second hypothesis confirmed that hospital management offers the possibility of human resource education to nurse managers. The third hypothesis confirmed that motivational needs, which influence graduates´ job choice, change with the level of education. The fourth hypothesis confirmed that setting up ``The Adaptation Process for Graduate Training{\crqq} positively evaluates nurse managers. Considering positive survey results it would be suitable not only to set up the adaptation process with graduates but also to use the questionnaire of testing needs which can help the middle management to nominate graduates with certain posts. There is a great significance in it and it is very important for career and integrating in work teams. The results of the survey could be lent to hospital management as an instrument of human resource optimization.

With the same force that human activities accelerate and amplify change in the biosphere, human agency can play a critical role in influencing future trajectories. However, managing increasingly complex problems is becoming ever more challenging. Among other things, it requires a systemic thinking about the future to anticipate how intertwined drivers may respond to rapid change. This thesis addresses such challenge in the context of contemporary wildfires, which are becoming increasingly complex to manage and a growing global concern. The study adopted a novel approach (Chapter 3) to study wildfire as a complex social-ecological system. The overarching aim is to generate insights into wildfire causes, effects and feedbacks to anticipate future wildfire risk and inform management strategies that can prevent potential impacts. I combine different disciplinary lenses, multiple spatial scales of analysis and participatory methods to analyse wildfire dynamics in the Chiquitania region, located in the Department of Santa Cruz, Bolivia, at the southern edge of Amazonia. This region has a unique tropical dry forest that is susceptible to changes in climate and fire regimes, and a rapidly expanding agricultural frontier. During the recent 2010 drought, large wildfires affected this region intensifying public concern about potential 'mega-fires', particularly given predictions of more extreme seasonality in the future. The first research paper of this thesis (Chapter 4) evaluates the effects of wildfire recurrence on the forests of the Chiquitania using ecological surveys. In addition to significant biomass loss, the observed patterns in species abundance and dominance suggest that the forests respond to recurrent fires through a shift in tree species composition, with fire-tolerant species becoming more dominant. The second research paper (Chapter 5) analyses future wildfire risk in the Chiquitania region using fuzzy cognitive mapping. This conceptual modelling approach engaged different actor groups in the region to integrate their perspectives of the regional wildfire dynamics. Semi-structured interviews informed the scenario assumptions which considered failure to respond in time to wildfire risk, as well as implementation of alternative management strategies. Unexpectedly, the fire management strategy showed less trade-offs between wildfire risk reduction and production compared to the fire suppression strategy. The high vulnerability of the agricultural production to wildfire risk has implications for local communities that largely depend on agriculture for subsistence if future climatic conditions become drier. The third research chapter (Chapter 6) uses interviews and focus group discussions to analyse how different forms of knowledge and perceptions of fire relate to prevalent wildfire risk strategies in the Chiquitania. The analysis reveals that strategies are in tension between two conflicting narratives and understandings of fire. On this basis, a deliberation process is proposed with the potential to integrate opposing views into more inclusive and collective solutions to manage wildfire risk within a reflexive governance framework. The fourth research paper (Chapter 7) complements the above ground-based studies with a regional assessment of wildfire risk based on remotely sensed land cover, anthropogenic and climatic data. Maximum entropy was used as a probabilistic modelling approach to simulate future wildfire risk scenarios driven by different development trajectories, and assuming changing climatic conditions. Important determinants of wildfire risk were climate, road development, deforestation and density of human settlements. Positive feedbacks between rapid frontier expansion and drought conditions almost doubled potential biomass loss compared to estimates in the 2010 drought. Land used for agriculture and cattle ranching showed particularly high levels of wildfire risk, with serious implications for the subsistence and economy in the Chiquitania if the agricultural frontier is expanded at an accelerated rate. The combination of new findings and modelling tools developed in this thesis are relevant to inform wildfire risk management decisions in the Chiquitania. The timing is fitting as the regional government of Santa Cruz is developing a ten-year programme to address increased wildfire risk at the time of thesis submission, and the recently launched Regional Fire Platform promotes dialogue about possible solutions. More broadly, the approach to study wildfire as a social-ecological system has proven extremely useful to generate insights into different facets of a complex problem that is becoming a major concern in most of Amazonia and globally. This thesis generates important theoretical and practical contributions to the study of social-ecological systems, and provides a concrete example of how increasingly complex problems can be anticipated and managed under climate change and rapidly changing conditions with a more integrated and socially inclusive approach that can inform adaptation decisions for more sustainable futures.

This work deals with project management in chosen company. It has two parts. The first part is theoretical, which is focused to theoretical treatment of the subject. It explains what is the project, management of projects, organizations of projects, processes of project management, what is target of project, communication, control, changes and risks and more. In the practical part I focused to concrete company and project management and than I analyzed concrete project. Name of the mentioned company is OHL ŽS, a.s. It is company from Spain, which acts all over the world. In the Czech Republic has the base in Brno. This company has several divisions and every of them is focused to different professional architecture. I have chosen division of structural engineering. This division builds all kinds of buildings. It could be construction of new buildings or reconstruction. To analysis of chosen project I used various business documents, contracts with investor or suppliers, document which include billing, timetable. I especially used my experience with projects of this company, and I was part of this project. Name of this project is Reconstruction of cladding including replacement windows and insulation. During the analysis of project I found a couple major gaps. If we could avoid these gaps, we could increase profit. These graphs is especially in management. At the beginning there were appointed two temporary construction managers. They doesn't care about result project, because they knew that they will not be to the end of the project. These gaps are because there is missing motivation system. Project manager can´t affect results of employees. It doesn´t depend on performance of employees, they always has the same wages. For elimination of these gaps I proposed several suggestions for improvement. The first suggestion is modification and extension of motivation system. New motivation system include personal evaluation. This evaluation depends on performance of employee. The second part is bonus from over profit. The next suggestion is make a new working position. This position would take care about controlling and project documentation. During the building project, especially at the end is construction manager very busy. It depend of decision of construction 63 manager what kind of activity will have prefer. Project documentation and administration or controlling of building works. If they are doing everything correct and technology are respect. Suggested position would take care about invoices, real work, which is done, project documentation, controlling of budget. The third suggestion is purchase of small machinery such as chipping hammers and drills. At this time they rent all devices. Rent is higher than purchase price. The last suggestion is use credit to restoration of fleet. At this time they have obsolete fleet, because the bought all cars by cash. It is not conveniently.
