Monteringsupplägg: examensarbete angående axelmonteringen på
Volvo CE Components
Rapporten undersöker Volvo Construction Equipment Components axelmontering för axlar till Dumper och Hjullastare. Arbetet har utförts med intervjuer, studiebesök på andra fabriker och en detaljerad studie av monteringsavdelningen och dess angränsande avdelningar vilka levererar artiklar till monteringsstationerna. Undersökningen har resulterat i ett förslag där fördelarna av en stationsbaserad montering och fördelarna med en linjemontering kombinerats. Arbetet presenteras i rapporten och i en dator animerad 3D simulering av förslaget till en ny monteringslayout. Jag anser att Volvo CE Components och montörerna på monteringsavdelningen skulle gynnas av monteringslayouten som redovisas i rapporten..
Arenabygget, ris eller ros? : en hedonisk prisstudie av kommuninvånarnas värdering av den nya arenan.
This study is an examination of the stadium fever prevailing in Sweden. It is built stadiums in Sweden as never before. The high cost of these constructions end up in the end at the Swedish taxpayers. The study examines through the hedonic pricing of real estate how local residents value the new stadiums. The result indicates that local residents put a positive value in the costly and sumptuous buildings.

Vibrationsdämpning av värmepump
Thermia Värme AB is one of the market leading manufactures of heat pumps. In order tomaintain this position, the company wants to improve the vibration characteristics of theirproducts. The aim of this thesis is to develop product design changes that lead to a reductionof vibrations in the heat pump Thermia Diplomat 8.The main cause for vibrations in the system is flow pulsation and mechanical forces inducedby the scroll compressor. Vibration is transmitted through the compressor piping and receivedby the heat exchangers, from where it is further transmitted to the connection points for theradiator and heat source circuits.A number of design changes in order to improve the vibration characteristics have beenevaluated through calculations and practical experiments. The changes have included thecompressor and heat exchanger mountings, the compressor suction and discharge line pipingand also pulsation dampening.The results of the experiments show that the vibration levels in the connections for the heatingand brine circuits can be decreased strikingly through changes in suction and discharge linepiping.

The objective of the report has been to determine the reliability of sprinkler systems in Sweden and to present suggestions on measures to increase the reliability. The main conclusion that has been drawn is that the reliability of sprinkler systems in Sweden is 92 percent according to the analysis of Swedish statistics, and that this figure finds support in statistics from other countries. Further results are that the quality of design, installation, maintenance and inspection of sprinkler has to be improved and that the Swedish incident report has to be revised..
Energivinst vid hybridisering av hydrauliskt system
Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.
Hommage till slit och släp - västerbottniska arbetarskjortor i en undersökning om mönsters påverkan på kläder
Hommage till slit och släp is a tribute and a resarchabout patterns relation to clothes. The primary goalof the project was to examine how a pattern couldchange the apperance of a garment and how thegarment?s construction and material would impactthe pattern. The formative survey was about thesparsely populated areas in the north of Sweden andhow theese areas have been treated by the swedishgovernment. The issue worked as an inspiration andmethod which I used in the patternresearch.
Glasbruksvillan och jakten p? den f?rsvunna dekoren
This thesis aims to propose a plausible design and construction of the lost gable
pediments of the Glassworks Villa in F?glavik, anno 1875. Through a
combination of building inspections, photo analysis and 3D modeling, the
researcher utilizes the combined results to digitally recreate the decoration that
once adorned the gothic revival villa's gable, to serve as basis for its actual
reconstruction. The study further highlights the use of modern technological
tools, such as 3D modeling software, to further enhance the understanding of
historical architectural elements. The researcher also emphasizes the challenges
and considerations involved in preserving and reconstructing historical
architectural details for future conservation endeavors..
Partnerskapet: trygghet eller en illusion? : En intervjustudie med lesbiska kvinnor som ingått partnerskap
I have critically examined heteronormativity as it permeates our society and questioned ?identities? as designed and constructed, leading to certain identities being seen as normal, while others are regarded as abnormal.I have had a discussion with my informants about love, monogamy, amicable and relationships. Every couple has basically isolated themselves after they became a couple and they feel secure with one another. The partnership is very important for my informants, partly because they see the partnership as a legal and economical security. However, these aspects are not crucial to the decision that they chose to marry, for the main reason is love and the desire to take the relationship one step further.
Måste Aftonbladet minnas vad en jämtländsk by heter? : En kvalitativ studie av hur jämtländska nyheter porträtteras i rikstäckande press
For years the northern parts of Sweden, Norrland (translated: North land) has been considered mystified and exotified by the southern, more urban parts of the country. The rural Norrland ? though 60 percent of Sweden ? is seldom a part of the common conversation, meaning that most of the people living in the southern parts simply have no idea what is happening in the north. The one million people living in Norrland, on the other hand, every day gets to know what happens in the south on the evening news. The question about this possible structural relation between the urban and the rural became a large matter of cultural debate in the spring of 2015, If this thesis is true, we have a problem on our hands; can the national news be considered national if half the country is misrepresented? That question is what this essay is trying to find out by analyzing two of Swedens largest national newspapers.

Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören
The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.
Diskursordning och hegemoni : Representationer av en skola
Den här artikeln utforskar, genom en mångperspektivistisk diskursanalys, tidningsartiklar, en vetenskaplig artikel, ett myndighetsbrev, bloggar och ett reportage skrivna om en specifik grundskola i Sverige, som har blivit känd för sitt lyckade utvecklingsarbete med elevernas studieresultat. Enligt denna artikel är bilden som förmedlas genom media mycket positiv tills en artikel följd av en blogg, förändrade diskursordningen på ett hegemoniskt sätt. Den här artikeln beskriver den diskursiva förändringen i relation till den social- och historiskt utbildningspolitiska kontexten, till stor del dominerad av en nyliberal ideologi, där mätning och ranking fokuseras mer än skolutveckling i form av inkludering och lärande..
Postanställdas konstruktioner av arbetsmotivation: En jämförande studie mellan postsorterare, lagledare och brevbärare
In order to broaden the understanding of work motivation the aim of the study was to compare how three different teams within the same organization constructed motivation. The three teams consisted of post sorters, team leaders and mailmen. Three focus group interviews were conducted with three men and eight women. The interviews were transcribed verbatim and thematically analysed with QSR NUD*IST. The result showed both similarities and differences in the construction of work motivation in the three teams.
Livscykelanalys av flerbostadshus ? energieffektiviseringsåtgärder för minskade koldioxidutsläpp
The importance of energy- and environmental issues has increased, and the work towards reducing carbon dioxide emissions plays a major part. The European Union has set up goals for the membership countries to work towards this to happen. The carbon dioxide emissions in Sweden have been reduced the last few years, but there is still a lot to do. About 30 per cent of Sweden?s carbon dioxide emissions generate from energy usage related to housing, this is why the housing sector is of interest to examine.
