Today electronics becomes more and more complex and to keep low costs and Power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

The swedish national board of housing, Building and Planning,recommends that all stakeholders in the construction industryperform a moisture control design to make sure that the buildingachieves good moisture resistance. Since June 1, 2006 there are nospecific requirements or quantitative values for air leakage.Although the swedish national board of housing does presentrequirement that the building envelope must be sealed so that theclient?s requirements for specific energy consumption and installedelectric power for heating purposes are met. Despite this, studiesfrom SP shows that few buildings meet the client?s requirements inspecific energy, which increases the risk of occurrence ofcondensation-related moisture damage.This study aims to evaluate curtain walls connections from airsecurity and moisture safety.

The purpose of this paper is to study how people without home experience social services and how they experience their space of action when they meet social services. In order to answer these questions, a qualitative approach has been used. The empirical material consists of five interviews with people who have contact with social services because they are homeless. To support my analysis of the space of action for the persons being interviewed, I?ve used two theoretical perspectives, power analysis by Michel Foucault and Rational Choice.

Looking at the debate on nuclear power in Sweden, the issue of risk is central to understanding the difficulties in resolving differences between proponents and opponents. I sought to answer the research question: "how is the concept of risk constructed in the nuclear power debate in Sweden?" Four main aspects of risk construction were defined and investigated to identify differences between sides in the debate. Through a qualitative study of the debate and its actors I found clear differences in respect to all four aspects of risk construction. First, the perception of nuclear power as a "normal risk" is common among nuclear opponents in contrast to a largely probabilistic view among proponents.

This essay will discuss consumption as a strategy for creating one?s identity for persons with visible disabilities. Along with this, questions asked and answered are concerning how lack of inclusion in the fashion industry affects the informants? consumption of clothes and how the informants discuss identity in relation to their disability. Compulsory able-bodiness (McRuer, 2006) is a main theory that will influence both the discussion and the results.

At Rottneros pulp mill mechanical pulp is bleached with hydrogen peroxide. The changes of bleaching chemicals that are used for different grades are taken from bleaching tables; however these tables are old and need to be updated. The purpose of this thesis was to be the basis of new documentation.In this thesis three pulps where studied with the aim to find the optimal bleaching chemical changes (total NaOH/VP-quote) for each pulp. The pulps were taken from the filter before the bleaching tower and the pulps were bleached in the lab. The most important pulp property in this study was the brightness and how that was influenced by the chemical dosages.

There is a growing interest for ethical consumption, in general as well as in the clothing industry. The consumption of ethical clothes is a complex phenomenon though, where aspects such as quality, style, function, price, time assets, accessibility and ethical attitudes affect the decision making. Researches that have been executed show the diversities in development between different countries. There are fairly strong indications that the ethical clothing market is more advanced in the United Kingdom than in Sweden and therefore these two countries are objects of this research. The aim with this thesis is to describe and explain what have affected the development of the ethical clothing market in the United Kingdom compared to Sweden. For that reason a qualitative approach has mainly been used, where deep interviews with people within the ethical clothing industry have contributed to most of the empirical part. As a complement secondary data such as statistics of the two countries have been used in order to investigate our area. One useful tool, among others, to investigate the macro environment is the SLEPT model.

This report summarize a simple and efficient way to convert 2D into 3D designs. It explains the benefits of a 3D design compared with 2D, and how those benefits may be used.It will also give the reader a presentation of the company Clean Air Technologies, which for the most part constructs cleaning facilities for power plants. How to create 3D-libraries for some of those facilities will be introduced in this composition.The collaboration with Clean Air Technologies has resulted in several 3D animated movies and rendered images. This has increased the quality of the companies offer presentations, which has made it easier for the prospective customer to get an improved overall image of the power plant design..

This thesis aims to research how megacorporations are depicted in popular media by analyzing the video game Cyberpunk 2077. In this assignment I focus on how the narrative of said game discusses economic globalization, megacorporations specifically which is accomplished using a set of theories such as: exploitation, commodification and capitalist realism. The analysis is constituted using a modified version of narrative analysis in order to better suit my research field as well as presenting a clear and concise structure a reader can follow. This study concludes that Cyberpunk 2077 constructs a dystopian world with the megacorporations holding the political power where the majority is constantly oppressed by the 1% in power. Things that we find human are questioned and diminished in order to increase the profits of those in power which tends to be the megacorporations.

The interest for children´s clothing has increased in society. More and more children are born and parents are older when they have children. Education has become a natural feature in most people´s life, just as both parents often work today. The households have therefore better economy and thus greater consumption opportunities. Parents are, in greater extent, looking for personal and different clothing with focus on quality and, to some extent, exclusivity rather than just a cheap and functional garment.

This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.

The aim of this study is to create an increased understanding of shared leadership and how it takes shape in the relationship between first-line managers in human service organizations. Shared leadership is seen as a complement to the traditional one-man leadership and briefly means that two managers share the role that usually is held by a single leader. The study has a qualitative approach based on semi-structured interviews with managers in human service organizations. The interviews mention the mangers thoughts and experiences about shared leadership and gain approval in the hermeneutic science field. The study is analyzed based on symbolic interactionism where perspectives from the theoreticians Mead and Goffman are used.

In 2002 the local council of Lund, Sweden, decides to implement the UN Convention of the Rights of the Child. A number of actors, such as the state, the civil society, the political society and the bureaucracy, participate in the political process with different authority and points of departure. This thesis studies the actors´ interactions from an inside perspective by applying concepts such as political power, democracy and implementation. The methodological departure is action research from within, a local NGO, the local board of Save the Children Sweden. The results of the study indicate that governance and steering of the implementation process at the communal level is weak.

The social elite on Öland and in Möre in the south east of Sweden during the Iron Age is described on the basis of the archaelogical record, such as graves, settlements and traces of pre-Christian central places. The material is discussed to see if traces of an elite are to be found. The power configuration between Öland and Möre is also discussed.
