The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

The motivation to conduct the study was that external project managers have become more common the last decades. At the same time trust is considered to be a key factor for efficiency and good results for the organisation. The group members? trust in the leader is built on past experiences of both the leader at a personal level, and the leaders? relationship to the task. Trust can also be built over time, when the leader earns trust from the group members.

Communication is essential for the survival of an organization. The management formulates strategies to ensure thatthe organization will get to where they want it to go. The strategy is then communicated to the co-workers through the line manager. But who is to say that the co-worker experience the message the same way as the line manager or the management for that matter? The purpose of this study is toinvestigate how the middle managers at Southern Älvsborg Hospital experience strategic internal communication andfurther how they communicate with their co-workers.Through a case study approach, the case being the communication of the hospitals research strategy, I conducted 13 interviews.I analyzed the material from the interviews using a hermeneutical approach and I used an interpretative approach to get a deeper understanding.

This study sets out to investigate the social significance and political use of three historical places, from the theoretical starting points of landscape, objects, society and rituals. The Teutoburger Forest in North Germany has had an international effect, being a german national icon during the reformation and through two world wars, Old Uppsala is a place of great importance for the creation and reproduction of Swedish national identity during several hundred years, and Eketorp ring fort on Öland in Sweden is of more regional importance. All these places have been used for social and political reasons through history. History can be used in a constructive or a destructive way. This study stresses the importance of a critical scientific tradition..

In support to a decision to be made by the Swedish central competent authority on a minimal amount of straw for conventional growing-finishing pigs, a study using 168 pigs provided 7 different amounts of straw (20, 40, 60, 80, 100, 200 or 300 grams/pig/day) was performed. The straw was provided either once or four times per day. Detailed behaviour observations were made using focal animal sampling and continuous recording for one hour between 9 and 10 am and again between 3 and 4 pm. The data analysis is presented in three ways: broken stick model, polynomial trend line and logarithmic trend line. No method was suitable on its own but the use of all the methods simultaneously was found to portray the data in the best way.No significant differences were found when comparing pens provided with straw once or four times per day.

Under b?rjan av 2000-talet utvecklades f?retagens marknadsf?ringsstrategier till att bli mer digitala. Utvecklingen skapade en ny del av n?ringslivet d?r influencerbranschen idag har v?xt sig stor. Livsstilskonsumtionen som influencers bidrar till medf?r h?llbarhetsutmaningar s?v?l socialt som ekonomiskt och ekologiskt.

The thermal response of a borehole field is often described by non?dimensional response factors called gfunctions.The g?function was firstly generated as a numerical solution based on SBM (Superposition BoreholeModel). An analytical approach, the FLS (Finite Line Source), is also accepted for generating the g?function. In thiswork the potential to numerically produce g?functions is studied for circular borehole fields using the commercialsoftware COMSOL.

At SIA TallOil's pellets factory in Latvia wood shavings and saw dust are dried with flue gases from a gas burner. TallOil wants to replace the gas with a biofuel that is available at the pellet plant. The reason for this is the unstable gas market in Europe in combination with the fact that TallOil wants to improve its profile as supplier of renewable bio fuels. In this project the technical and economical possibilities for a fuel conversion to ether bark powder, wood shavings or wood powder have been investigated. These fuels should be burned in one of the following applications: TPS BioSwirl, VTS Multifuel burner or Saxlunds bio fuel combustion plant Due to the fact that the fuel alternatives available are relatively common except for bark powder, the work has mainly been focused on bark powder.

Every year, Swedish municipalities transfer considerable amounts of profit from public housing companies to the owner municipality. Municipalities are allowed to do this, provided that the money is used to pay for certain purposes. But there are no legal repercussions if they do not comply. Not all municipalities choose to transfer profits. Based on partisan theory, this difference could be explained by the political governance of the municipality.

The purpose of this study is to examine how Viking Line, Tallink Silja and Birka Cruises work with economic and environmental sustainability, and also to see how they work with new environmental legislations. In 2015 a new environmental legislation will be introduced, by the name Sulphur directive. The Sulphur directive entails a reduction in Sulphur dioxide emissions from ships where the emissions cannot exceed 0,1 percent. There are three alternatives to achieve the new environmental legislation, the use of Marine Gas Oil, LNG or scrubbers. All three alternatives will lead to increasing costs for the shipping industry.

This report deals with activities that from a CSR perspective are considered to create a shared value for a medium-sized construction company in Sweden. The CSR definition used in the report is the European Commission?s since it reflects the valuecreating aspects of CSR, in contrast to the traditional philanthropic aspect of CSR.Companies in the building construction industry have difficulties identifying activities that create value in society and in the company. The aim with the project is to, from a CSR perspective, identify and evaluate value creating activities in a building construction company. The activities will be evaluated with respect to competitiveness and how they can be implemented into an organization.

När man går på bio eller sitter hemma i soffan och ser på film tänker man sällan på filmens egentliga innehåll och symbolik. Man ser på filmen för att slappna av eller för att tänka på något annat. Syftet med denna uppsats är att framförallt analysera de kvinnliga karaktärerna i Lord of the Rings ur ett genusperspektiv och att höja medvetandet om dessa karaktärers roll i filmerna. Framför allt kommer fokus att ligga på de tre kvinnliga gestalterna som skildras. Jag har även valt att kortfattat behandla karaktären Rosa Kattum, som kontrast till de andra kvinnorna då hon skiljer sig från dem på ett för uppsatsens syfte intressant sätt..

Det finns stor potential i byggbranschen att förbättra produktionsprocessen på en arbetsplats med hjälp av nya planerings- och modelleringsverktyg. En produktionsteknologi som är särskilt intressant att studera är det platsgjutna betongbyggandet. Här utförs många olika, men sammanhängande, moment tätt på varandra och processen styr mycket av andra processer som följer efter detta skede. Det är därför viktigt att kunna planera och kontrollera byggandet med platsgjuten betong med enkla och effektiva planeringsverktyg. En relativt ny modelleringsteknik som har stor potential att förbättra produktionsprocessen är 4D CAD.
