Hur lokal bioenergi kan bidra till att Uppsala kommun når klimatmålet 2050

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..

Via Paris till Irak : en alternativ väg för rekonstruktionen av det postkonfliktuella samhället?

AbstractThis study examines the conclusions made by Roland Paris in his case study of fourteen major post-war reconstruction efforts following the end of the Cold War, and applies them to the current reconstruction process in post-war Iraq. Paris found a common denominator of the fourteen cases ? a belief that a rapid liberalization process, turning war-torn states into liberal market democracies, would foster sustainable peace. Paris calls this belief ?Wilsonianism? after Woodrow Wilson, who was one of the first advocates of it.

Vindkraft ? en alternativ drivkälla för tågtrafiken

Målet med detta examensarbete, utfört på uppdrag av Vectura Consulting AB, har varit att undersöka möjligheten att ansluta en vindkraftpark till järnvägens kontaktledningsnät. Möjligheten att koppla om vindkraftparken till järnvägens hjälpkraftnät, som bland annat förser växelvärmare och signalsystem med effekt, har också undersökts. Eftersom kontaktledningsnätet och hjälpkraftnätet arbetar med olika frekvenser och spänningar, 16? Hz och 15 kV respektive 50 Hz och 22 kV, måste därför en komplett krets för frekvensomvandling, spänningsomvandling och omkoppling tas fram. Projektet har begränsats till en del av Botniabanan, sträckan Örnsköldsvik-Nordmaling.I denna rapport har trafikfrekvensen på den valda sträckan på Botniabanan undersökts för att bestämma en genererad effekt till inkopplingspunkten, samt för att undersöka när det kan vara lämpligt att koppla om till hjälpkraftnätet.

ABL:s utvidgade värdeöverföringsregler då ett aktiebolag är komplementär i ett kommanditbolag : Utgångspunkt ur NJA 2014 s. 604

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.

ESDP - att vara eller inte vara -Rationella förklaringar och ledarskapets betydelse för ESDP:s födelse i Köln 1999.

At the EU summit in Cologne in 1999, a consensus was reached concerning the common foreign and security policy within the European Union. It was decided at the summit that the WEU (Western European Union) should be incorporated into the EU - whom would then be given military capability to act autonomously without the necessity of Nato involvement. This essay investigates the factors that made this agreement possible from a rational choice perspective, but also from the perspective of the power and influence on negotiations on behalf of various types of leadership present at the meeting. Many nations at the summit of Cologne where for the creation of a military force in the form of ESDP (European Security and Defence Policy) within the Union, and many where against such a decision. However a consensus was reached and that is what this essay shall try to explain.

Kampen om Din Världsbild - En Diskursanalys av Ekelunddebatten från Sydsvenska Dagbladets Kultursidor

AbstractDue to the success of the Populist Party Sverigedemokraterna in the Swedish election of 2006, the daily paper Sydsvenska Dagbladet published a number of columns written by well-known academics, writers and debaters. Their aim was to address the question of why this happened in the election and what it is in the Swedish society today that brought forward these trends. The first and the last word was given to the writer Fredrik Ekelund, and therefore the debate was named Ekelunddebatten.The debaters are fighting to present their view of the world as the only option when categorizing different societal groups and appointing themselves as group representatives. My aim is to unravel these different conceptions of the world and to do this I use the Dicourse Analysis as a method. I discuss the results with Critical Discourse Theory as a theoretical base and also from the view of the current societal discourses: the working class discourse, the multicultural discourse and the discourse of political correctness.I mainly observe four different conceptions of the world with different posing of problems.

Samhällskritik från gatan : En studie av argumentationen i hiphopmusiken utifrån ideologi

Purpose: Which type of social critique does hiphop music present and is it possible to categorize the critique?Is it possible to categorize the social critique ideologically on the basis of socialism, liberalism and conservatism?Procedure and method: A qualitative text method has been used to see which arguments the songs portray. Two different analyzes has been used. The first one was a theory based on Thomas Denk and Daniel Silanders book: Att studera demokratisering and Arvidssons book: Musik och politik hör ihop and its purpose were to categorise the critique. The second one was based on a book by Reidar Larssons: Politiska ideologier i vår tid.

Synchronous Latency Insensitive Design in FPGA

A design methodology to mitigate timing problems due to long wire delays is proposed. The timing problems are taking care of at architecture level instead of layout level in this design method so that no change is needed when the whole design goes to backend design. Hence design iterations are avoided by using this design methodology. The proposed design method is based on STARI architecture, and a novel initialization mechanism is proposed in this paper. Low frequency global clock is used to synchronize the communication and PLLs are used to provide high frequency working clocks.

Hur elever med ickesvensk etnisk bakgrund tolkar två lektioner i skolan : samt ett uttryck av maktförhållande mellan lärare och elever

This paper examines how pupils with a non-Swedish background, in a secondary school in Stockholm?s suburban, Sweden, interpret and absorb the contents of school-room classes. It also examines whether the interpretations are influenced by a power-relation between teacher and pupils. The pupil?s interpretations, including their values and perceptions as regards to the content, are central to our study.Firstly, classes on world conflicts and corporal punishment for children were observed and these observations were the foundation to this study.

Fjärrvärmesystem

This is a report written for an examination project C-level, on the subject of energy. The examination project is a product of the FVB Sweden AB (district heating bureau). It started with a meeting with Stefan Jonsson FVB Sweden AB, were he explained the content of the project, and from this a presentation of the problem was made. The problem that needed to be solved was how they could control the valves in the system to provide heating to everyone in the system. The valves are often oversized so the pump in the heating plant would have to be enormous to be able to provide enough flow to be sufficient, if everyone in the system had there valves fully opened. I came up with two solutions to the problem, one was a wireless network that could keep track of the valves and the other solution was an extra sensor that was placed on the radiator.

Resursrelaterad informationshantering i uthyrningsverksamheter : En studie av verksamhetsstödjande IT-system och identifikationsteknologier

The management of assets in organisations today can be a challenging task and optimising their usage is critical to ensure maximum profit. For rental businesses offering tangible products efficient management of movable assets are an essential part of the business strategy. The main purpose of this study is to investigate how asset management and asset information management can be carried out in rental businesses and in what ways information technology can support it. By doing a literature review combined with a case study where three rental businesses and their use of information technology were examined we could identify several important aspects regarding asset information management. The results we have found is that rental businesses with a high degree of digitization in existing asset information management systems are able to rationalize existing work processes, which in some ways changes the roles of employees.

Uigurerna - de Andra. En postkolonial studie av en muslimsk minoritet i Kina

In this thesis I have used post-colonial theory to analyze the Uyghurs, a Muslim minority group located in Xinjiang province in the Northwest of China, and their identity shaping process in relation to the dominating Han Chinese. I have analyzed the possibilities to use the power perspectives in post-colonial theory, especially Edward Said's Orientalism and the creation of the Other in a new context, where the main focus is on the Uyghurs through the eyes of Han Chinese. I have argued that Han Chinese, with colonial tendencies, have created two generalizing pictures of the Uyghurs; one romantic picture to use as an exotic tourist attraction and one threatening picture that portray Uyghurs as Islamic terrorists to win support in international politics. The thesis is a qualitative single case study with the aim of gaining a deeper understanding for the Uyghurs as well as examine possibilities of widening the analyze areas for post-colonialism. My conclusion is that the power perspectives in post-colonial theory are usable implements also for non-western contexts and in this case function as a way to understand the identity shaping process for the Uyghurs and their relation to Han Chinese..

Konst på internet idag : En retorikanalys av konstverksamma organisationers självpresentationer

This is a qualitative study about Art transformation and commodification in the digital age. The study applies a rhetoric analysis with the aim to understand how art sellers, gallery owners and entrepreneurs take part in this transformation process through their websites? presentation texts ?about us?. The analysis is related to communication theories but it is also inspired by other theories such as Gramsci?s hegemony theory and Bourdieu?s cultural critical theory.

De tre civilisationernas kontinent - En studie om Sydamerikas civilisationer i en globaliserad värld

In this thesis I analyse civilizations in South America. I construct civilizationalnarratives through the method of emplotment, to build a historic continuity, whichI subsequently connect to the theoretical framework. The theory emphasise that,when confronted with globalization and free market capitalism, civilizationsembark on different strategies to challenge the power of transnational marketforces. I find that South America is a polarised continent, and is divergingconcerning the relationship towards the USA and free trade agreements. On thesame time the issues that concern the social movements are not being reproducedin a significant matter at state level.

Kartläggning av nätförlusternas storlek inom Mälarenergis elnät

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.
