Alternativa byggsystem för att minska transmissionsförlusterna på miljonprogrammets byggnader

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.

Transporter för hållbar utveckling : En optimering av utsläppsberäkningarna inom Coop

Man?s impact on the environment is something that increasingly becomes topical in today?s society. Because of this, several companies have started to take interest in the effects they?re responsible for, not least considering their image. Emissions of carbon dioxide generated from goods traffic are accountable for a large part of the total emissions of greenhouse gases in the world.

Bygga broar mellan kulturer: En studie av skönlitteratur, identitet och integrationsprocess

The aim of this Master?s thesis is to explore the meaning of literature forliterate immigrants in regards to identity and integration. The study is based onqualitative interviews with eight Swedes of various backgrounds, but with thecommon experience of an immigration process. In addition to being migrants, therespondents are also public library users who have an interest in literature and whoread literature during their leisure time. To analyze the empirical material ananalytical framework, consisting of a number of analytical concepts from Libraryand Information Science, Literature Science, and Sociology, has been used.

"I am neither a freak nor a monster" : En analys av Paradise Lost-dokumentärernas argumentation

The purpous of this master?s thesis is to explore how the swedish public library evolved between 1890-1911, before the state implemented the library reform in 1912. The material used to cunduct the study concists mainly of texts published during the time frame of the thesis in the form of books, booklets and articles from Folkbiblioteksbladet, a journal dedicated to the subject of the swedish public library.Drawing upon Habermas theory of the structural transformation of the public sphere and Bourdieus theories about taste as social distinction and symbolic capital, the thesis seeks to show how the public participated in the evolvement of the public library and which aspects of society that contributed to the public library?s establishment as an institution. The findings are also discussed in relation to previous research of the history of the Swedish public library.

Neonate mortality in fallow deer (Dama dama) in relation to bed-site selection and habitat use

The level of neonate mortality in a free ranging fallow deer (Dama dama) population at the Koberg estate in south western Sweden was investigated using radio-tracking techniques. During this study a total of 36 fawns (17 ?, 19 ?) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low, since only 1 of 8 non-surviving fawns died from predation by red fox (Vulpes vulpes). The spatial behavior of the fallow deer neonates were examined at two different levels i.e.

Att bygga ett bibliotek : En studie av funktion och rörelse i tre nyinrättade biblioteksbyggnader - Kungliga tekniska högskolans bibliotek, Sambiblioteket i Härnösand och Vitterhetsakademiens bibliotek

A large part of research about libraries and library buildings in Sweden has been focused on how the building looks not how it functions with the library. The aim with this master?s thesis is to study how a library building is functioning and how its users are experiencing it. This is studied in three libraries, Kungliga tekniska högskolans bibliotek, Sambiblioteket in Härnösand and Vitterhetsakademiens bibliotek. With the questions of how they were planed, what did the libraries want from the new building and which of these demands were realized.

Möjligheter till ökat utnyttjande av fosfor genom grödan med mineralgödselmedel

The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

En surrealistisk soppa? En komparativ studie av Stefan Hammaréns sopptrilogi och surrealismens litterära kriterier

The purpose of this essay is to establish whether the so called ?soup trilogy?, med en burk soppa (2001), konservöppnare bok (2003) and på burklös mark (2005), written by Swedish-speaking Finn Stefan Hammarén is to be considered as surrealism or not. The methods used to determinate this is close reading, a technique used for finding a text?s distinguishable traits, and comparative analysis. First of all, the criteria of surrealist literature found in André Breton?s (1896-1966) Surrealist Manifesto, and other sources, as well as the criteria for the surrealist literary technique cut-up are presented and evaluated accordingly.

?Jag är hemlös, inte lealös?: En undersökning om hemlösas informationsbehov

The aim of this Master?s thesis is to study the information needs of the homeless. The main focus is to investigate what kind of information needs that are to be found among the homeless and also how information is exchanged and shared by the group. Another aspect of our study includes the sources that are used to fulfil these information needs. The homeless use of the library, as one of these sources, is also examined.

Informationskompetensen i användarundervisningen

This master thesis investigates the user education. Christine Bruce has presented a theory of information literacy in her research which has resulted in seven different aspects of information literacy. In this study I wanted to investigate what aspects there were and what they looked like in a practical educational situation. The methods used for this study were observation and a questionnaire. I analysed the observations by using Bruces aspects of information literacy to group the observed activities into the different aspects.

Konstruktion av UPS-modul

This master thesis describes the development of an UPS module. UPS is an acronym for Uninterruptable Power Supply. The UPS module has been developed at the company AerotechTelub AB. The UPS module delivers the necessary voltage and current in case of a power interrupt. If a power interrupt occur, the computer system has one to three minutes available to store data and shut down correctly.

Modellbygge och regulatordesign av tröghetsmomentsimulator tillreferenssystem för stridsvagn 122

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

Design, anläggningsmetoder och skötseltekniker för hagmarksbestånd :

SUMMARY Establish a pasture There is many valuable nature and culture landscapes in Sweden that has developed during a long period of time, throw natural processes or human use. Unfortunately lot of these are disappearing. My thought with this work is to explore the possibility to establish new areas with similar qualities. The motive for this is that attractive countryside biotopes are well worth to use as model to enrich the urban landscape. Another thought has concerned the people that establish, build and manage landscapes and parks. They often have varied views, both coming from a difference in background and previous experiences.

Elektromagnetisk skärmning genom mekanisk omkonstruktion

This is a master degree thesis at Royal Institute of Technology (KTH) betweenÅngpanneföreningen and Programma. KTH is the examiner, Programma is the client andÅngpanneföreningen is mentor for this project.Programma has a product called TM1800 that has problems with EMC; the problem is thatthis product does only pass the CE-check with a small safety margin. This problem can besolved by reducing the radiation from the electric components in the product or by reducing offix base frame. In this degree thesis the focus is only on mechanical redesign.The main problems right now depends on the long distance between the screws, there is anisolating layer on most of the parts and the forces between the joints are too small. The mainfocus is to solve these three problems.The best solutions are when the whole base frame is more or less redesigned instead of onlyredesigning some of the connection points.

Undersökning av nätverks-RTK-meddelande tillsammans med olika GNSS-mottagare : vid nätverks-RTK-mätning i SWEPOS®-nät av fasta referensstationer

Nätverks-RTK (Real-Time Kinematic) är en metod för positionsbestämning med Global Navigation Satellite System (GNSS) i realtid. Metoden kräver att en driftledningscentral kan kommunicera med de GNSS-mottagare som använder referensstationsnätet, för att bland annat skicka ut korrigerade GNSS-data. I Sverige erbjuder SWEPOS, ett nät av fasta referensstationer, en tjänst för nätverks-RTK-mätning, som förväntas ge en mätosäkerhet på mindre än 15 mm i plan och 25 mm i höjd (över ellipsoiden) (med täckningsfaktorn k = 1 i bägge fallen). Den teknik som idag används av SWEPOS för att utföra positionsbestämning av GNSS-mottagare är Virtuell Referensstation (VRS). VRS kräver tvåvägskommunikation eftersom mottagaren skickar in sin absoluta position till nätverks-RTK-programvaran hos driftledningscentralen, var beräkningarna av korrektionsdata sker, innan de skickas tillbaka till mottagaren.
