This thesis conducted at the University of Uppsala investigateshow well a prefabricated building component from the manufacturerMasonite Lättelement AB can be incorporated into ahouse projected to accomplish the demanding criteria of a passivehouse. The thesis is organized as a comparison betweenthe prefabricated elements and an on-site built component fromthe passive house area of Oxtorget in Värnamo, Sweden. Theaspects investigated were air leakage, energy, moisture, economyand noise conditions.Results of the comparative analyzes shows that the prefabricatedproducts were capable of accomplishing the requirementsof passive houses and therefore this thesis should beviewed as a basis to confirm that the technology of prefabricatedbuilding components today in Sweden are mature enoughto be a significant part of the passive houses that are to be builtin the near future. The development of prefabricated technologyis of crucial significance if we are to accomplish the goalsof reduced energy consumption by the year 2020..

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Title: Facebook girls, a qualitative study of social medias and Facebooks impact on young girlsNumber of pages: 32Author: Mirja LarssonTutor: Amelie HössjerCourse: Media and Communication studies CPeriod: Autumn 2010University: Division of Media and Communication, Department of Information and Media,Uppsala UniversityPurpose/aim: To discover any possible difference between young girls and older girls in their wayof using Facebook.Material/method: Personal interviews, literature, electronic sources, Internet sources.Main results: The younger girls are not as aware as the older girls of their exposure on Facebookand the possible down-sides of their frequent Facebook-usage. Young girls in general use Facebookas a source to form their identity.Keywords: Facebook, identity, young girls, Cooley, Elza Dunkels, Altman and Taylor.

In Sweden, exercise takes a great part in people?s lives. Health and a good conditioned body go hand in hand. Many Swedes exercise in groups, with aerobics or a similar form of workout at a training facility. A regular workout lasts for about an hour and is accompanied by music.

The task for this thesis is to design a tool that is used to cut-out preforms of thermoplastic adhesive and also to make an estimate of costs for the stamping tool. The tool is used in the repair process at the MCM production line. The result of gathered information has affected how the design of the stamping tool has developed. The handling of thermoplastic adhesive in the repair process is one of the factors that influenced the design. The adhesive is sensitive for exposure to moisture. Therefore an automated feeding system of the adhesive is not recommended. The users wished for an automated stamping tool.

Studien bygger på två 24 timmars ljudinspelningar utförda från två olika städer iSverige. Syftet med undersökningen var att se om det gick att urskilja akustiskaskillnader mellan två olika städer i Sverige. Studien har tagit mycket inspiration av R.Murray Schafer arbeten inom soundscaping, samt Pijanowskij, et al., (2011) ramverkför att kunna kategorisera ljuden utifrån dess ursprung och funktion. Olikaundersökningar har genomförts med hjälp av kvalitativa intervjuer, samtfrekvensanalyser av det inspelade materialet. Båda metoderna användes tillsammansvid utvärderandet av ljudmaterialet för att se hur vida informanternas svaröverrensstämde med den frekvensanalys som genomförts.

Detta examensarbete omfattar akustiska undersökningar utav en desinficerande diskmaskin av typ Getinge 8666/8668 och har utförts på Getinge Desinfection AB i Växjö. Vi har undersökt hur man med enkla medel kan sänka ljudtrycksnivån i maskinens närhet. Mätningar har utförts på diskmaskinens torkprogram, där torkfläktarna är de mest dominerande ljudkällorna och ljudet främst är luftburet. En systematisk analysmetod bestående av införandet av successiva dämpningsåtgärder visade att de dominerande ljudvägarna går via taket, golvet samt till viss del spalter i maskinens väggar. Genom att isolera både tak, golv och spalter kunde ljudtrycksnivån sänkas med totalt hela 5,9 dB.

This study aimed to describe children?s experience of living with overweight or obesity, by using a literature-review. The study includes eleven articles, data is from children between ages 5-15 year. The result occurring were in the areas; Quality of life and self-esteem, Social company, Body concept and weight reduction and Psychological unhealth. BMI above what is recommended gives a negative influence on quality of live and self-esteem.

The highly toxic man-made substance referred to as dioxin (polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)) causes severe health damages both to humans and other organisms, with lethality as its worst. Because of the toxicity several risk assessments has been performed on dioxins trying to determine at what concentration there are no risk of exposure. Resent years of research has discovered that these substances are not only anthropogenically but also producedin natural processes, like volcanoes and forest fires. To investigate if there is a need to take these naturally formed dioxins into account in the risk assessment processes, interviews with persons at relevant institutions in Sweden has been made. Analyses of existing risk assessment methods and political documents were also made to complete the picture.

The global Positioning System (GPS) provides location and time information as long as there are unobstructed lines of sight to four or more GPS satellites. However, when this is not the case the signal may be inaccurate or sometimes even completely blocked. In these situations the Inertial Navigation System (INS) is an appropriate choice for positioning.  An INS has already been proposed in a previous thesis by Erik Andersson and the objective of this thesis is to fuse the GPS with the INS in a proper way. A part of this project is to decide the reliability of the GPS.Three methods for GPS reliability detection have been proposed. One method based on the statistical properties of each of the separate systems, and two methods based on the statistical properties of the residuals between the GPS and INS.

This essay examines the criteria for a peaceful cemetery. First there is a short history of the Swedish funeral place. After that follows the definitions of a peaceful place according to environmental psychology. From these definitions an analysis method is constructed for identifying a peaceful cemetery. The analysis method contains six criteria, shape of the entrances, existence of sound, vegetation character, the cemetery?s demarcation, the cemetery?s management and what feeling the cemetery mediates.The analysis method is put into practice on three cemeteries, Överklinten cemetery, Stockholm forest cemetery and the old cemetery in Malmö.

The aim of this paper was to describe the phenomenon of threats and violence within a Swedish penal institution. The study was thematized according to the three main research questions. These were as follows; The threats and violence prison staff have experienced in their workplace (I) how these experiences affected them in their work performances (II) and in their private life (III). By a qualitative design, in-depth interviews were carried out with four persons who are, or formerly have been, gainfully employed at a penal institution. Concepts from the theory of symbolic interactionism and a theory of human action have been used in the analysing process of this paper.
