The study was carried out as a time study of five wood chippers placed on trucks,so?called huggbilar. They are trucks with built?in wood chipper, chip bowl and crane pulling a chip trailer. The system is used for chipping wood fuel, transporting, and delivering the chips to heating plants.

The market for biofuels from the forests have had a positive development and the job initiators for this master´s thesis wanted to examine the profitability of a method for harvesting forest fuel, which was unfamiliar to them. The method was the ?long tree tops-method?, here called the LT-method. The LT-method is characterised by the fact that timber is harvested as the only roundwood assortment while the rest of the stem, which in other cases would become pulpwood, is harvested as forest fuel together with the logging residues. The method is based on the assumption that advantages in handling of the forest fuel assortment such as increased load weights for forest hauling and truck transportation, should compensate for the lower price for pulpwood when sold as forest fuel. The aim of the study was to compare the profitability of the LT-method with the GROT-method (harvest of timber, pulpwood and logging residues) and conventional logging without any harvest of forest fuel, and aslo to try to identify factors affecting the profitability of the different methods.

In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

University of VäxjöSchool of Social SciencesBachelor Thesis in Political ScienceTitle: ?Sverigedemokraternas valframgångar 2006 ? En ulv i fårakläder??Author: Emma Haraldsson and Åsa NeuschützTutor: Emil UddhammarThe aim of this study is to explain Sverigedemokraterna?s electoral success in 2006 and the essay assumes that some form of change has occurred. To study this change two hypotheses have been constructed. The first hypothesis concerns the change within Sverigedemokraterna and the second hypothesis concerns the change of the Swedish voters attitudes.Kirchheimers catch-all theory is used to explain the change in Sverigedemokraterna. The catch-all theory states that parties have to change their structure to maximise the number of votes.

Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.

This study takes place within a publicly owned art producing organization and dwells on the problems of a change process that the organization was involved in. Both leaders and staff were disappointed by the way the change process had developed. The management team explained the outcome by referring to the uniqueness of working with artists who constantly put their own personal objectives before the benefit of the whole. The aim of this study is to find a complementary explanation to the one the management team provided us with; an explanation that can help in the understanding of the dynamics of a change process. Can perhaps theories on information, communication and change processes give an alternative explanation to why the change process faltered? To investigate this, we have used a qualitative single case study.

The essay discusses the effects that changes to the office plan have on organizational culture. Information about actual change as well as expected change in organizational culture was gathered before the empirical research was initiated. The empirical research was carried out at the Customer Logistics department at Ericsson through: an interview with a manager in charge of the relocation and design of the office, a manager for the specified department and also five employees of this department. The empirical studies show that there was a significant change in organizational culture and that results were not always as expected. There was a loss in symbolic actions, which needed to be compensated for, a perceived reduction in spontaneous communication, and a mixed response of perceived change in social interaction.

Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.

Title: Change Communication within organizations ? How perceptions differ between managers and employees in an organizational changeAuthor: Emma Ender & Fanny TeschTutor: Anne-Marie MorhedPurpose: The purpose of this thesis was to study and compare different perceptions of change communication between managers and employees within two smaller organizations. We wanted to examine how the communication process within the change was carried out. We also aimed to compare the results with change communication models of Johansson & Heide (2008) and Lewin (1951), and also existing concepts, to see if our result differed from earlier research. Our key questions to answer were: How do managers communicate a change to the employees in two smaller companies? How do the managers think that the employees perceive the information about the change? How do the employees perceive the information about the change? How does change models from previous research correspond to, or differ from the change process?Method/Material: The material used in this thesis consists of a total of twelve interviews with both managers and employees at two small companies.Main results: The main results shows that communicating a change is complex, and that it is difficult to create models and theories for the phenomenon, as each change is unique.

The use of bio energy in Sweden has increased during the last few years and with every passing year, bio energy produces 3-4 TWh´s more energy than the previous year. The increase in the use of bio energy makes it an interesting prospect for forest companies to produce bio energy from the forest. Sveaskog has a fairly extensive bio energy programme, mainly in southern and middle Sweden. Their activity regarding bio energy in northern Sweden has been very restrictive or even non-existent. Because of this, during the winter of 2003-2004, Sveaskog initiated a number of degree projects with the purpose of looking at the use of bio energy in northern Sweden.

The product structure of the fuel tank installation is one of the most complex product areas at Scania. Caused by the number of parameters, which affect the fuel tank installation, a product structure is created which is very difficult to handle. Knowledge exist that the structure in a nearby future will be considerable more complex. The purpose of the study has been to understand in why this complexity exist and find ways to break the trend of a growing product structure. The goal was to achieve a more standardized fuel tank installation.A theoretical study was performed in order to bring knowledge in relevant areas both in general theory but also in documentation at Scania.

För att skydda den europeiska produktionen av bränsleetanol har EU satt upp höga tullar på importerad etanol. Vi har analyserat hur marknaderna för socker och etanol fungerar i Brasilien och EU, därefter försökt förutse vilka samhällsekonomiska effekter ett borttagande av importtullen i EU kan ha. Vi finner att etanolpriset i EU sjunker, därmed ökar efterfrågan. Bensinkonsumtionen ökar på kort sikt i både EU och Brasilien, då ett lägre etanolpris medför ett lägre pris på bensin via den inblandningskvot av etanol som finns i vanlig bensin. På längre sikt kan så kallade ?flex fuel?-bilar bli allt vanligare och bensinkonsumtionen kan avta.

The essay discusses a process of change at probationservice office. The purpose of the change was to decrease specialisation and increase flexibility of the probation officers. The change encountered several problems where the correctional supervisor was percieved to act unsurely and indecisively whilst parts of the staff constructed and implimented several courses of action to prevent the process of change..

In non-profit organizations, surplus of the organization goes back to the organization's members. We have noted that Hyresgästföreningen initiated a change in 2005 when the organization merged its local membership registries to a national registry. There are few studies explaining how non-profit organizations are using management in an organizational change. What happens with the business management at an organizational change that is similar to the change in Hyresgästföreningen? The aim of this thesis is to explore how the governance of a nonprofit organization is changing at an organizational change.
