Tvåsamhället : Om att förhålla sig till normer som skaver

This study focuses on single peoples construction of their lifes in relation to normative heterosexual coupledom. It is based on five interviews made with single women and men at the age of 24 to 51 who live by themselves. The queer theory which puts the heteronormativity in question is used as a theoretical framework. Discourse psychology functions as an analytic approach. It focuses on the use of language in the construction of reality in a world of determinant discourses.

3D-modellering i AutoCAD -att skapa en digital huskonstruktion

3D-modelling in AutoCAD This thesis is done in cooperation with LB-Hus in Bromölla, and have aimed to establish a digital AutoCAD model of one of the company?s house types and to find out what opportunities there are to do visualisations in the form of images directly from the programme. Modeling has been carried out so that the very construction of the house is included. Interiors and installations, with the exception of the ventilation system, have been left out in the model. The model has been created with solid models after a comparative study made between solid models and surface models to find out which option in this case was the easiest to handle and took up the least space.

Rocchio, Ide, Okapi och BIM : En komparativ studie av fyra metoder för relevance feedback

This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

Vad tror blivande religionslärare? En livsberättelsestudie om sex lärarstudenters syn på religion

With this thesis I have examined the views of religion among six comparative religion teacherstudents, with the perspecitve of their life stories. I have also examined what stance they want to take due to their personal beliefs in their forthcoming teaching. To achive this I have used in-depth interviews among the six soon examined teacher students, and within the interviews I have had a particularly focus on turning points of the students? life stories. Later on I have used their turning points in an analysis with the hypothesis of ?Rites des Passage? and ?Structure and Anti-Structure?.In my survey I have found a significant relationship between the students? life stories - inparticularly their backgrounds and tourning points - and their views of religion.

Underlag för solcellsproducerad el i Stockholm : Potential och klimatpåverkan

The City of Stockholm has decided to invest in renewable energy and especially in photovoltaics. The objective of this thesis is to investigate the photovoltaic potential on roof areas that the city possesses and to further investigate some buildings of the Property Management Department. The thesis also compares some existing photovoltaic plants with the solar irradiance map which shows available roof area on each building in Stockholm. The report ends with a literature study about the climate impact and greenhouse gas emissions of photovoltaic.The total available roof area suitable for photovoltaic plants is estimated to 700 000 m2, with a potential electricity production of 110 GWh per year. This corresponds to 17 % of the City of Stockholm?s yearly electricity consumption.

Utveckling av lastmodell för Uppsala fjärrvärmenät

The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.

En brännskadad kropp och vägen tillbaka : En litteratur studie ur ett patient- och närståendeperspektiv

Background: Being subjected to an extensive burn injury affects the victim´s physique, social life and its psyche. A burn injury can be determined as a trauma. Burn injuries often make the patient suffer from pain, anxiety and lack of a social life. Sister Callista Roy´s theory was used to analyze the result of the study. One of her goal is to promote the adaptive function of self-perception.

Kunskapsteori och kunskapsorganisation: En diskursanalys

This Masters thesis concerns epistemology in Knowledge Organization KO, as a field of study in Library and Information Science LIS. Using a theoretical model by Birger Hjørland and foucauldian discourse analysis as springboards, this study analyses three epistemological discourses in the practice of KO. The aim of the study is to show how these discourses are constituted and demarcated in relation to KO, as well as to examine how they fit into Hjørlands model. A brief historical outline of some epistemological trends in LIS is sketched, as well as examples of how different epistemological schools influence different parts of KO, e.g. information retrieval, indexing- and classification theory.

Modellering av reserv- och nödkraftsystem i JAS 39 Gripen

Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.

Metoder för prediktion av kardiovaskulär sjukdom med njurfunktionen

This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..

Forskning och museer : en kartläggning av fältet

Today every organization is committed to some kind of environmental scanning in order to get necessary knowledge of the world around them. The acquisition, organization and storage of information in combination with a strategic use, is today an important factor for a successful organisation in any sector of our society.In this Master thesis I have studied how an organisation such as The Confederation of Swedish Enterprise (Svenskt Näringsliv) handles its information resources. I have also looked at the flow of information within the organization. The Confederation of Swedish Enterprise is Sweden?s largest business federation representing 50 member organizations and 55 000 member companies.

Vem lägger livspusslet? : På jakt efter livspusslets innebörder i media 2009-2011

This essay studies the concept of "livspusslet", a term in swedish that directly translates as "the jigsaw puzzle of life". In recent public debate it has been used to articulate issues concerning the combination of family life and a professional career. The empirical material consists of newspaper articles from nationwide daily newspapers Dagens Nyheter and Svenska Dagbladet between 2009 and 2011. The concept of "livspusslet" relates to the debate about family values, gender equality and the public view on the issue of combining family life with a career. The widespread use of the concept indicates that the social practices surrounding the debate over family policy is shifting.

Systemutveckling och användbarhet -Att utnyttja användbarhetstester i systemutvecklingsprocessen

Den här rapporten behandlar frågeställningen om hur man kan anpassa systemutvecklingav ett informationssystem enligt livscykelmodellen till att inkludera användbarhetstester. Frågeställningen grundar sig i att god användbarhet inte är ett explicit uttryckt mål i Andersens beskrivning av livscykelmodellen. För att besvara frågeställningen har vi utvecklat och testat ett bokningssystem åt en mindre verksamhet. Utvecklingsarbetet har bedrivits enligt en egen anpassning av livscykelmodellen. Testerna har utförts enligt metoden cooperativ evaluation.

Studie av värmeflöden i befintligt bostadsbestånd : Utvärdering av energieffektiva besparingsåtgärder

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.
