Bojkonstruktion
The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.
En kartl?ggning av inv?ndiga f?nsterluckors utbredning och konstruktion
Interior window shutters can be found in historical buildings, but they are an uncommon occurrence in
modern buildings. In modern contemporary construction, large glass panels are often the ideal because
of increased light inflow and for architectural purposes. However, this can generate several negative
effects, such as increased energy loss, lack of privacy and high sunlight penetration. Problems that
window shutters could have accommodated historically.
This thesis identifies a lack of knowledge about interior window shutters in the Swedish building
stock.
Offer, aktör eller överlevare? : En diskursteoretisk analys av unga tjejers utsagor om att leva med sex som självskadebeteende
The purpose of this study is that through a discourse theoretical perspective, analyze young girls 'statements about living with self-injuring by sexual behavior. The aim is to locate the discourses that surround them, visualize how discursive constructions affect these young girls' identity as victims and/or actors in relation to self-injury, the sexual violence and in meetings with the professionals within the health authorities. In addition discourse theory as an analyze method, the authors also use Nils Christie's (2001) theory of the ideal victim and Ingrid Landers (2003) theoretical perspectives on normative femininity. The authors of the study show a diversity of discourses that surround the young girls. All discourses contain normative actor- and victim?s positions that young girls constantly are obliged to relate to, which partially conflict with social constructions of the idea of victim and femininity.
Maskuliniteter : Genusnormernas inverkan på individers sociala förutsättningar
The purpose of the thesis Masculinities ? Gender and its Impact on the Social conditions of individuals is to perform a critical study of how gendered norms influence the social conditions of individuals. This has been done by a problematization and the attempt to answer the question of how the hegemonical masculinity can be analyzed as a discourse, and how the structural aspects of this discourse inflict on the social conditions of masculinities.The question was divided into the analytical themes: the boarders of the discourse, the institutionalization of the discourse, the actuation of the discourse and the agents of the discourse. The theoretical frame is constituted by the theory of discourse by Michel Foucault, the theory of the hegemonical masculinity by R.W. Connell and a subversive identity theory by Judith Butler.
Bostadsbubbla i Stockholm kommun : Sann existens eller falsk spekulation?
In light of the massive property bubbles that have been bursting in the USA, Spain and Ireland during the last decade, the aim of this thesis is to clarify whether ? or to what degree - the municipality of Stockholm might experience a property bubble in the near future. The municipality of Stockholm is undergoing a housing shortage and house prices have risen during the last few years. Neoliberalism and property bubbles are used as a theoretical framework in this paper. The methodology consist of semi structured interviews, analysis of documents and statistical data from Eurostat, Valueguard and the Swedish administrative authority; Statistiska centralbyrån (SCB).

Jämförelse mellan en träbro och en betongbro : En LCA-analys med fokus på koldioxidutsläpp samt en LCC-analys
This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.
Höghus : En alternativ lösning på vår snabba stadsexpansion
Uppsala like many other Swedish cities is affected by heavy housing shortage, in terms of too few existing flats and residents within the city limits. Every semester thousands of new students are facing the same problems of finding themselves adequate accommodation. The waiting lists for flats and student-dorms are getting longer for each year, and the situation is just getting worse. Simultaneously, Uppsala?s ambition is to increase its population and expand as a Swedish metropolitan, according to the Swedish governmental environment goals. This paper investigates and analyses the possibilities of expanding a city?s population by building high-rise buildings.
Lyckliga i alla sina dagar? : Makt, kön och heterosexualitet i tre Disneyfilmer
The purpose of this thesis was to examine the ways in which the constructions of heterosexuality and gender in three Disney movies about princesses affect the power relations between men and women in the movies, and how discourses on gender and heterosexuality have changed over time. Research questions were:How do characters in the movies talk about gender and heterosexuality?How does the interplay between gender and heterosexuality affect the power relations between men and women in the movies?What are the likenesses and differences between movies from different time periods?Discourses were mapped out using a model based on Ernesto Laclau and Chantal Mouffe?s political theories. These discourses were then analyzed with a theoretical framework consisting of Yvonne Hirdman?s concept of gender system and gender contracts, Judith Butler?s view on the heterosexual matrix and an understanding of power relations based on Michel Foucault.
Modiga pojkar och hjälpsamma flickor : En diskursanalys hur manligt och kvinnligt framställs i läseböcker från 1950-talet, 1970-talet och 2000-talet
Societies are surrounded by unaware attitudes and views about what is masculine and what is feminine and this can contribute to people being raced differently. Boys and girls are shaped to think and act in different ways from an early age because of their gender. According to the curriculum in the Swedish school system, the school has an important task to prevent such perceptions young people have about sex and gender. Reading books are still a central source where students gather information in the Swedish school. Therefore, I find it interesting to examine how gender is produced in three Swedish reading books from three different periods (1950s, 1970s and 2000s) to see what similarities and differences there are between the texts and the study has been based on three questions:How are men/boys and women/girls described in the reading books based on their characteristics, interests and pursuits?How much space in the texts are represented by men/boys and by women/girls?What masculinities and femininities can be found in the texts and which ones are the most desirable?I have used a text analysis in my research to analyse the three reading books and based my theory on that gender is a social construction.
Skårby : En kultplats med lång tradition
The ancient site of Skårby, situated about twenty kilometres south of Stockholm, includes one very large cairn enclosured by a stone wall with a small cairn attached to it. Cairns are originally thought of as graves, but resent research shows that they are more likely to have been religious objects. The constructions are seated on a small hill with a view over the lake Bornsjön which used to be a bay of the lake Mälaren. This place has been the object of worship throughout the whole Bronze Age. Over the years the manifestation of the worship changed, but the place for it stayed the same..
Anonymous ansikten : En undersökningar av några svenska dagstidningars konstruktioner av hackernätverket Anonymous
This study examines how a couple of Swedish daily newspapers construct the hacker network Anonymous, with an aim to discuss its possible effects. The question was: In which ways is the network Anonymous constructed in a few Swedish newspapers? 26 articles from four chosen newspaper were analysed, but because of many similarities in content, only 10 were chosen for deep analysis. With Fairclough's model of critical discourse analysis as chosen method, constructions varying from the images of heroes to villains were found as a result. The most common construction was that of Anonymous as a threat, which was most often exaggerated compared to what actions were actually described in the texts.
Joker och forumspelspedagog : yrkestillvaro i variation
By means of text creation I approach, reflect upon and try a number of aspects of my own professional existence as a joker in forum theatre and as a forum play pedagogue.This essay is structured like the days of a week and it specifically relates three problematic situations: first, a Monday containing a case of discrimination during the performance, then, a glimpse from a Wednesday when I failed to use the time with enough consideration of our common work and, finally, a Thursday when I was professionally questioned.These three situations are described thoroughly and then they are tried by me. This is carried out partly by reasoning, partly by using for example sociological, pedagogical and above all philosophical texts in order to widen my understanding of my existence as joker and forum play pedagogue. When writing this essay I really realized the importance of taking the reactions of the spec-tators into consideration. I have had the opportunity to develop thoughts about the way in which reflection is created and thoughts about different layers of reflection. I have also pondered over the way in which I distinguish between forum play and therapy as a forum play pedagogue.
Sunda energieffektiva väggkonstruktioner för morgondagens flerbostadshus
Detta examensarbete har utförts vid högskoleingenjörsprogrammet Byggteknik och design vid Kungliga Tekniska högskolan och i samarbete med Ramböll Sverige. Syftet med denna rapport är att undersöka och analysera dagens ytterväggskonstruktioner för framtidens energieffektiva flerbostadshus. Ytterväggskonstruktionen som är en del i byggnadens klimatskal, har en viktig och betydelsefull funktion för att kunna klara av framtida byggnaders energikrav. För att en väggkonstruktion ska fungera finns det en rad andra påverkande faktorer som måste tas hänsyn till. Därför kommer examensarbetet att fokusera på ytterväggskonstruktioners byggfysikaliska egenskaper såsom lufttäthet, fukt, uppbyggnad och beständighet. För att kunna lösa uppgiften har vi varit i kontakt med åtta olika byggnadsentreprenörer i Stockholmsområdet och utfört studiebesök ute i produktionen. Det finns flera faktorer som styr valet av ytterväggskonstruktion för projektet och på grund av detta finns det en rad olika typer av ytterväggskonstruktioner som används i dagens byggande av flerbostadshus. I vår jämförelse mellan sex olika ytterväggskonstruktioner har vi analyserat byggfysikaliska egenskaper och produktionsmetoder utifrån samma grundparametrar.
Metallhantverket i Uppåkra ? en studie av ett hantverksrelaterat material
The aim for this essay is to identify and distinguish the metal casting of Uppåkra during late Iron Age by examine related material that primarily consist of finds made with a metal detector. I intend to, by analysing maps, concentrations in the detector material and probable constructions within the settlement, find patterns that can indicate a metal casting activity. The results of the essay show that a number of concentrations can be seen and that they both indicate metalworking activities and to some degree a structural specialization in the settlement. The exclusive artefacts also indicate that Uppåkra was a settlement with over-regional functions when it comes to traditions dealing with metal casting..
