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 purpose of this master?s thesis is to evaluate anew method for load-shedding, the voltage controlled underfrequency load-sheddingdeveloped by ABB. This report presents a comparison between conventionalunderfrequency load-shedding and this new method for load-shedding.

The EU has decided that it should be possible for consumers to get information about the origin of the electricity they buy. Therefore, there is a need to examine different systems for electricity disclosure. In this thesis two ways of disclosure have been studied:? Certificate system. A certificate system involves two parallel markets, one for trading electrical energy and one for trading certificates of origin.? Separated Markets.

This thesis is made by Carl Persson and Alejandro Saavedra for Gryaab. Gryaab is Gothenburg?s water processing plant and produces about 60 GWh biogas annually with a flow around 1150 Nm3/h. Gryaab wants to research their possibilities to become independent with electrical energy and the possibilities to enrich, upgrade biogas. The use of methane rich gases like biogas and natural gas is today low in Sweden compared to major parts of the world.

Getrag All Wheel Drive i Köping tillverkar i huvudsak transmissioner till fyrhjulsdrivna bilar.De har sett en besparingspotential om det är möjligt att sluta tillverka ett mätplan på pinjonghuvudets ovansida, detta används för att mäta in pinjongläget vid slutmonteringen av växlarna.I perioder har det uppstått kassationer på grund av slipbränningar på mätplanet men en stor del av besparingen ligger i kortade bearbetningstider. En önskan har även varit att det skall gå att få en ökad toleransvidd i monteringen för att minska antalet justeringar av monterade växlar.För att utreda om det skulle vara möjligt att ta bort mätplanet har ett antal koncept arbetats fram för att utvärderas gentemot de kriterier som måste uppfyllas.Konceptet med störst potential valdes ut med hjälp av olika jämförelsemetoder.Studien visar att det finns en möjlighet att bestämma pinjongläget genom att mäta i dubbhålet.De ändringar som måste göras är:- Ny mätstation vid inmätning av pinjonglägesshims där tjockleken påpinjonghuvudet mäts.- Ny meshingstation där pinjongen orienteras med hjälp av ett lagrat kontrollvärdeistället för att lokalisera med hjälp av mätplanet.- Ny kontrollstation för inmätning av pinjonghöjd där det måste gå att lokaliseraväxelhuset för att kompensera för lutningen på grund av att det inte går attmäta rakt under röraxelns centrumlinje.Möjligheten att helt utesluta mätmetoden bör undersökas.

The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP. The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in buildings..

ABSTRACTPurpose: The purpose of the study was threefold. Firstly, to investigate if a four week program in pain rehabilitation had any effect on how much individuals with persistent pain worked and their degree of kinesiophobia. Secondly, to study if there was a correlation between how much these individuals worked and their degree of kinesiophobia. Thirdly, to study if there was a correlation between the change in these variables.Method: 112 patients who had participated in a four week rehabilitation program took part in the study. The study had a retrospective design, which was based on a review on medical records and consisted of three minor parts.

Syftet med rapporten var att undersöka möjligheten och lönsamheten för installation av något av följande system; FVP eller VBX-modul som kan återvinna värme ur frånluften.

Rooted in Industrial Ecology (IE) theory, this report evaluates how urban agricultural concepts and techniques, can contribute to improved ecological sustainability within the inner city boundaries of Stockholm. An overarching literary study as well as an interview was carried out, resulting in a qualitative analysis followed by suggestions for practical implementations. A substantial convergence was found between the eco-restructuring objectives of IE and the principal motives for urban agriculture. Consequently, eco-restructuring objectives are found in varying degrees in the presented urban agricultural techniques. Industrial symbioses, permaculture and combinations of urban agricultural techniques are tools which are capable of corresponding adequately to the diversity of urban settings.

In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..
