In this essay the renewal of the modern sacred art has been examined through the creation of three works of art from the art project ?Kyrkorummet?. The aim has been to show that renewal of the modern sacred art is best accomplished by the combination of the artist history and Bible knowledge and the open mindness of the beholder towards the new and creative, in order to communicate the gospel in modern time.The large extend of the art project demanded a selection of the art works. Therefore, three were chosen and they show the last supper and the baptism in a renewal way including both symbolism and creativity. To complete and facilitate the analyses, a theme, light and water, have been used as well as relevant theories in art history with Kandinsky as main art critic.Through the art project and it?s teaching, history in combination with present time through visits in different and modern churches, thoughts have been stimulated and the result has been new works of art that speaks of our time.

Today, literature is published in a wide variety of formats, it can be published digitally or in the more traditional paper format or as an audiobook. This thesis aims to take a closer look at fan fiction readers? reading habits and motivations for reading, as group accustomed to using different kinds of formats for their reading. It does so by analyzing fifteen responses to an online survey using only open-ended questions. The survey was posted online on fan fiction sites and could be answered anonymously.

The goal of this Bachelor project was to develop the Sundsvall42 website,whose name originates from the conference held in week 42 and during whichall the IT-companies in Sundsvall gather and hold a number of different lectures.The website has been designed to accommodate both speakers and partipicants.All partipicants and lecturers will receive a personalized page inwhich there are a number of functions which are available for use, including ablog for each workshop and a calendar. The program used to create this isLiferay and the operating system is Linux. The entire website is encoded usingLiferay and Java, but the website is not adapted for use with the smaller screensize of the Smartphone. However, because of the Responsive Design technology,the website is able to adapt to various devices such as the Ipad and Smartphonesand the website will be able to adapt to the screen sizes of these devices.As it has all been processed using open-source, everyone has the right to accessthe source code. It is also possible for anyone to make changes to the code ifsuch changes are required.

Groups that are often referred to as being dismissed in society in general is by some aspects also considered being so in political arenas. A recent compilation of existing research over structurally based objections of gaining power and positions within Swedish parliamentary politics highlight a lack of research considering whether sexual orientation could be such a discriminatory basis. Using a queer theoretical approach, and drawing on concepts such as heteronormativity and homophobia, the principal aim of this essay is to illuminate aspects of local parliamentary political areas where discrimination on the grounds of sexual orientation become relevant. In order to do so six in-depth interviews with homosexual politicians have been conducted. Finding a queer potential in certain ideological parliamentary political environments that enable homosexual politicians to be open about their sexual orientation, it still relies upon the individual to be confident enough not to interpret the political context as homophobic and heteronormative..

The relationship to professionals has proved to be a helping factor for personswith severe mental illness, but it is also a relationship characterised by anunbalanced power relation. The aim of this study was to compile and analyze theknowledge of what persons with severe mental illness themselves consider to behelping in the relationship to professionals, and to specifically analyse this from apower perspective. The analysis was conducted using Foucault?s ideas of powerand knowledge, and an empowerment perspective. The method used was anarrative review.

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

This study examines how formal mathematics can be taught in the Swedishsecondary school with its new curriculum for mathematics. The study examineswhat a teaching material in formal mathematics corresponding to the initialcontent of the course Mathematics 1c could look like, and whether formalmathematics can be taught to high school students.The survey was conducted with second year students from the science programme.The majority of these students studied the course Mathematics D.The students described themselves as not being motivated towards mathematics.The results show that the content of the curriculum can be presented withformal mathematics. This both in terms of requirements for content and studentsbeing able to comprehend this content. The curriculum also requires thatthis type of mathematics is introduced in the course Mathematics 1c.The results also show that students are open towards and want more formalmathematics in their ordinary education. They initially felt it was strangebecause they had never encountered this type of mathematics before, but somestudents found the formal mathematics to be easier than the mathematicsordinarily presented in class.The study finds no reason to postpone the meeting with the formal mathematicsto university level.

The aim of this thesis is to study how Denmark and the Danish people has been represented in the Swedish press and which images of them that appears. For this purpose I make use of discourse analysis and discourse theory. By analysing three cases were the debate about the Danish migration policy has been scrutinized in Swedish newspapers I seek to discover different ways of looking at the world. The study concentrates on the descriptions made by journalists and others who contribute to the debate in the media. The results show an image of the Danes as a people reluctant to foreigners and restrictive in their politics.

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

This study deals with some contested issues regarding prehistoric cultural development in Amazonia and the colonial impact on the native inhabitants of the area. It focuses on the relation between groups belonging the language families of Tupí and Gê, on one hand, and the different ecological zones that they inhabit, on the other. GIS mapping is used to visualise the distribution and movements of these groups in relation to ecology and the impact of European colonization. GIS is shown to be a useful methodology for analysing historical data derived from written sources and maps. The results of these analyses are discussed in the light of different theoretical perspectives.

One part of preventive conservation is controlling the lighting in the exhibitions. As a first step we have to accept the fact that the very act of displaying objects is causing them damage, and because the trend is for everything to be open to the public view all the time, the aim is to minimize light exposure of exhibits.This essay will present lighting options and relate them to the current recommendations. I have put the emphasis upon describing which methods one can use to minimize the degradation of exhibits on display by eliminating UV- and IR-radiation and reducing the visible light. The intention with this essay is to investigate the current lighting options and compare these to the recommendations on lighting exhibitions.The selections of different lighting options such as LED-, halogen- and energysaving lamps were made based on avaibility. Thereafter I did two types of investigations.
