Orust Kretsloppsakademi is a nonprofit organisation, with a goal of annually generate the same amount of electrical energy that is consumed. Orust is an island on the west coast of Sweden, north of Gothenburg. The population of 15 000 reaches 40 000 during summer, due to the large amount of vacationer. The total electricity demand is 174 GWh a year with a maximum power need of 32 MW. This report presents an analysis for the plausibility of their plan and from a power system stability perspective, the effects on the electrical grid.The conclusion is that the restraints for development of power generation from wind, solar and wave generation, are the power systems capability to transfer power, primarily in the transformers of the grid.

The aim of this study was to gain understanding and knowledge about first line manager?s need for support in their leadership and to get more insight into how they handle and perceives their work.The research method is based on studies of relevant theories and qualitative interviews. Eight respondents were interviewed with a structured 40 question questionnaire about how they experience their work and the support they get. The study shows that there are three important categories of people that are most significant to the managers in their need of support. They are their own manager, colleagues and co-workers.The conclusion is that it is important to create conditions for leaders to have good relationships with their closest manager, colleagues and co ?workers.

The purpose of this essay is to analyse how the leadership and the structure of the organization affect the process of changes within a specific department in Lunds kommun socialdepartment, from the director of social work to the co-workers at Utredningsenheten för ungdom och familj. We aim to answer the following questions;How does the structure of organisation affect the process of change?What do the co-workers and the leaders believe is the best way to engage the co-workers in the change?How does the leaders view their own leadership in the process of change?How does the co-workers view the leadership in the process of change?How does the leadership affect the process of change?To develop an organisation and to make it a functional, change is a necessity. The leaders are they who create the change but the co-workers are they who make it happen. In the process of change, leadership and the leaders capacity to create motivation for the co-workers, is therefore a matter that is decisive to its success.This is a study based on a qualitative method, where the interview is the main source of empirical material.

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.

This thesis work is performed on VSM Group Ltd in Huskvarna that produces sewing machines under the trademarks Pfaff and Husqvarna Viking. On these sewing machines is an application that helps the user to thread the needle. The aim with the work has been to study today's applications on VSM and their competitors' sewing machines in order to since developing a new Needle-threader that divides itself from all the ones used today. The objective with the work has been an entire new concept with an operational prototype.As a base the competitor analysis was used where today's applications was studied in order to identify positive and negative aspects of these. This led to a number off ?concept families? where different variants off the same ideas were collected and evaluated.

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.

During the years 2006-2010 Gotland University conducted seminars excavations in Västergarn parish on Gotland. Inside the wall a total of six house foundations have been found and a total of 127 combs have been registered. This thesis is based on a material study of the 127 registered medieval combs. The purpose of this thesis is to analyze the combs and with their chronology illuminate in which period the society of Västergarn was active. And also to find out what the material remains can tell us about the place and its people.

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.

Denna uppsats har haft examensarbetet ?MPLS kontra traditionell IP-routing - enjämförelse av resursåtgång? av Sebastian Viking och Anton Öhlin som stöd. Derasarbete jämförde processoranvändning vid routing med, respektive utan, MPLS.Resultatet påvisade att MPLS gav högre processorbelastning gentemot traditionell IProuting,tvärtemot vad teorin för MPLS säger. På grund av uppenbara motsägelsermellan teori och praktik ämnade detta arbete skapa en hypotes som undersöks deduktivtmed målet att bekräfta dess utsaga: På grund av MPLS, respektive IP:s implementation iunderliggande hårdvaruarkitektur, kommer ingen märkbar skillnad iprocessorbelastning att uppvisas vid tester där en routers uppgift är att förmedla paket.Vi har därför återskapat deras tester för att verifiera äktheten i deras resultat. Resultetfrån våra egna tester visade ingen uppenbar olikhet mellan routingteknikerna IP medCEF, respektive MPLS.

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.
