This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

Previous research has focused limited attention on how personality affects job search for university educated people in work and no studies have focused on the difference between active and passive job seekers. This survey-based study that examined university educated economists and engineers with 5-25 years of experience, showed that career ambition mediated active job search for the personality dimensions of openness, agreeableness and extraversion and also gave clear evidence that active job seekers have lower levels of job satisfaction, and higher levels of career ambition, agreeableness and extraversion, compared with passive job seekers. These findings provide a more nuanced picture of the impact of different recruitment strategies and provide a starting point for in-depth studies on passive job seekers.

Climate change is a phenomenon that know no boundaries. While focus on environment and climate change has become highly prioritized, nationalism has spread across Europe. Nationalism is by many considered to refuse action to combat climate change although some argue that nationalism could combat global climate change. Previous research on how nationalism is implemented in environment and climate politics has mainly focused on single parties. The thesis therefore aims to give a broad approach and compare how nationalism is used in environment and climate politics by analyzing 4 European parties with either ethnic or civic nationalism and different roles in their party system. With a qualitative content analysis on party programs and election manifestos the findings imply that parties use nationalism in the climate and environment discourse in a variety of ways.

AbstractOur bachelor degree thesis was carried out in collaboration with Ivar Petterssons Järnmanufaktur AB in Smålandsstenar. We were asked to replace their wedge housing, used to fasten the wires to the power lines, with a similar structure in a plastic material. The idea for this project started with Ivar Petterssons Järnmanufaktur AB having problems with the casting quality that forced them to perform expensive tests on each of the wedge houses to ensure the quality. They are currently produced in China which is also a major drawback because it requires expensive long delivery times.The method we used is Fredy Olsson's Princip- and Primärkonstuktion (1995). We have consistently been in the project on so-called "broad front", which means that you create several sketches, ideas and changes in parallel, and then evaluates all.

The aim of this study is to from a gender perspective to examine whether spa is a place for both genders or it is focused on female spa visitors only. Also to study the organisation`s point of view of gender performances within spa tourism as well as to see spa organizations views on gender distribution.To be able to answer the questions, the qualitative method was used in our research. The method is relevant to our study since we sought to gain a deeper understanding of the phenomenon. During the data collection we have used previous researchs and qualitative interviews. Overall we had conducted four interviews, one of which was the personal interview, two were made by email and one by phone call.

Title: Music teachers' practising of music - thoughts and values from a few music teachers. This study is about music teachers' valuation of practising music. The study is focused on the music that these teachers are devoted to but is not a part of their teaching in music. The papershows how the relation between music teachers and their ability to be devoted to practising music of their own choice, affects them as individuals. The study is carried out at a Swedish upper secondary school which has an educational programme that is focused on music.

This essay is an examination of the examples in Kant?s Critique of Judgement. The examples which I have focused on all converge in an idea of wildness. These examples of the beautiful are illuminated by a culture-historical perspective, where the literary and scientific travelogue genre is of great importance. Apart from being exegetic and culture historical, my method is also analytic.

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

Thesis purpose: The main purpose of this study is to empirically verify the applicability of Kozinets´ model on an interest, activity or lifestyle based online community, in order to develop an adaptive segmentation approach for segmenting online communities. Methodology: This research is deductive by nature, cross-sectional by design and undertakes a quantitative approach using self-completion questionnaire as a part of a web survey to collect the empirical data needed. Theoretical perspective: The main theories guiding our work and supporting the findings of this study include: market segmentation (descriptive and behavioural) and communities (consumer communities and online communities). Empirical data: A web survey with self-completion questionnaire used to gather empirical data from members of interest, activity or lifestyle based online communities. Conclusions: This study took the specific characteristics of online communities into more consideration than previous research and literature has done and also recognized that an adaptive segmentation approach is needed, depending on the communities of study.

Since the Maastricht Treaty the European Parliament has gained competence in the decision-making process and the Parliament is today one of two decision-making institution, next to the Ministers of Council. In this study the main focus has been to shed light over the negotiation culture within the European Parliament, which up till now has been a neglected research area. This is of great significance because the internal negotiations in the European Parliament decide the external negotiation position with the other institutions.After face-to-face interviews with MEP:s and assistants I have been able to identify certain characteristics to create an understanding of the negotiation culture in Europe's elected Parliament. The negotiations are oriented towards a problems-solving approach and the prevailing apprehension is consensus-based negotiations instead of the existence of political blocks. The committees are stronger than the European party groups, which further encourage negotiation.

The purpose of this essay is to examine the approach of the EU towards the reform efforts of Turkey and Bosnia and Herzegovina in the countries ambitions for EU memberships. The question formulation of the essay is whether there is differences in Turkey?s and Bosnia and Herzegovina?s qualifications for an EU-membership from an EU perspective. In order to better answer the question, we use two part questions. One is about the criterias and qualifications that need to be met in order to get a membership.

"Children's book is the best style means if you have something to say" is a quote by CSLewis that I focused on in this essay. As a future priest, I am aware of the problems thatexplain some of the Christian church pillars. In this essay I treat the Trinity in relation toteaching children in a future profession. Research in child and adolescent spirituality is onrampage, books with religious messages and ambitions to teach children about Christianethics and morals have been around since Sunday school introduction in Sweden. What arethe tools that can be used to explain even for scholars and theologians difficult concepts? Isit possible to meet kids on their own ground? I see an opportunity for this through theliterature, and the characters they already know outside the ecclesiastical sphere,In this bachelor thesis I have used perhaps one of the major works of children's literatureduring the 1900s, The chronicles of Narnia.

The parallel bars is used in physical therapy and is mainly used for patients who have to train walking and balance after a stroke or an operation. It consists of two long handrails with two legs on each handrail. These legs go down into two ground-plates and are locked at the wanted height with a pin. The parallel bars is an appreciated device and is used on a daily basis in many care units.The main issue with the manual parallel bars is that it is very difficult and heavy for a single person to adjust the height of it. If a larger adjustment of the height has to be done, the legs have to be adjusted one at a time otherwise the they will be locked.

The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.

In today's changing environment, an increasing number of companies are realizing thebenefits of analyzing business information and thereby stay competitive. By making use ofdecision support systems, known as Business Intelligence (BI), organizations are expected tocollect and process business data and thus get more out of their business.Nowadays it is not enough for organizations to have access to corporate data inside officewalls, they must also be able to bring the information "on the go", which has been thefoundation for the progress of mobile BI solutions. As the mobility increases and thecorporate data leaves the office, new risks arise, which is one reason as to why manycompanies hesitate at the idea of introducing mobile BI solutions.In this paper we explore two security aspects in the area of mobile BI solutions. Our researchquestion is as follows: How does security aspects affect a company's decision to acquiremobile BI solutions? The survey was conducted through interviews in cooperation with thefirm Optivasys, exclusively dedicated to the BI solution QlikView.A significant part of the theory we studied describes security as critical; however, ourresearch suggests a solution on how companies can manage the security aspects.
