Rengöringsmaskin av produktionslina : Rengöring av band i produktion

The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.

Shuttling Between Cultures: Expatriation in the Context of Sweden

Being a successful global business player depends on firm?s ability to mobilize its resources worldwide. For this reason getting the right people with the right skills, at the right time, at the right place is crucial and makes expatriation one of the most important issues of today?s business world agenda. In terms of expatriation; national culture provides the context for the whole process.

Valda verkligheter : En studie av svenska och engelska tidningars konstruerande av verklighet i rapporteringen kring Julian Assange

This is an analysis of how the Swedish newspapers Dagens Nyheter and Aftonbladet and the English newspapers The Independent and The Guardian reported about the sexual molestation and rape charges that were alleged against the Wikileaks founder Julian Assange in August 2010. Through a critical discourse analysis, a theme- and proposition analysis and a process analysis this paper aims to investigate how the above mentioned newspapers create reality in their articles. The purpose is to shed light upon with what means the journalists through the inherited structures of the newspaper illustrate actions and events, how they let other people get visible in the text and who is described as responsible for current events.    The results of the analysis shows that Aftonbladet uses a relatively large amount of propositions and speech cues to create an image of the reality that is almost explicitly angled. Dagens Nyheter and The Independent claims a higher degree of objectivity and through micro themes with different perspectives and few explicit statements they create a reality with plenty of room for the reader to make her own conclusions. The Guardian creates an image of the world where the Wikileaks is a great force of democracy and where actions are performed by humans as well as by objects and organizations.   .

Vindkraftverkens nedmonteringsprocess i Sverige

The first commercially produced wind turbines in Sweden are starting to reach theend of their lifetime after approximately 25 years of producing energy. The cost fordismantling the turbines, according to Ardefors et al. (2009), is calculated to be 1-2 %of the total investment of the wind turbines. The purpose of this master thesis is tomap the dismantling process of wind turbines in Sweden and try to find a sustainablesolution for the future.To make sure that a correct dismantling process takes place, and that the financialaspect is covered, a proposal for a financial guarantee is worked upon. A nationalunanimity will be created through a financial guarantee and the risk will be minimalof a third party getting afflicted.Studies of literature and interviews have been carried out.

The product is constructed by us, Patrik Svensson and Magnus Zetterqvist, for Christoffer Lindhe at Lindhextend AB. Christoffer has hired Martin Bergman at Smedjan 17 to make the design.

Konstruktion av current conveyors via makromodellering

A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

På klasskampens väg : Tidningen Gruvarbetarens inställning till strategier och mål för arbetarrörelsens fackliga och politiska kamp 1917-1925

Abstract: The aim of this study is to investigate the attitudes towards the labour movement?s strategies, goals and organisational issues in Swedish Miners? Union?s (Gruvindustriarbetareförbundet, hereafter Gruv) paper, Gruvarbetaren 1917-1925.The theoretical starting point is Engels? view on the class state. This perspective turns the question of socialism and the way to get there into an issue of working class power over the state. Another theoretical perspective is the partition of the labour movement into a trade-unionistic branch, seeing unions as financial organisations of interest, and a pro-state one, considering unions as political organisations.During the period investigated Gruvarbetaren was quite radical and advocated a firm class struggle strategy towards employers. Since these were considered unreliable, class struggle was seen as the only way to better the conditions for the working class.

Dr Jekell & Mr Hyde : En forskningsöversikt om barns upplevelser av våld i hemmet utifrån ett anknytningsteoretiskt perspektiv

Syftet med denna studie var att utifrån ett socialkonstruktionistiskt perspektiv och ett Foucault-inspirerat diskursanalytiskt ramverk visa på några av de sätt att tala om och förstå den bildterapeutiska processen som finns tillgängliga för och används av bildterapeuter. Syftet var även att beskriva hur dessa sätt att tala kan påverka bildterapeuter i det bildterapeutiska arbete de bedriver. Datainsamlingen genomfördes med semistrukturerade intervjuer med bildterapeuter. I resultatet lyftes tre distinkta sätt att tala om processen fram, som gav den tre olika innebörder. Dessa tre diskursiva konstruktioner framställde den bildterapeutiska processen som en blottläggande process, som en experimenterande process och som en reflekterande process.

Automatisering av spraytorkningsprocess

ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

Målstyrning inom den offentliga sektorn : en studie inom två sydskånska kommuner

The purpose of this investigation is to show how politicians state primary goals and how they break them down into secondary objectives within the sector of Child-and education area. This is supposed to create a general image on how the targeting process is handled within the public activity. Finally, this will lead us to what is necessary for the targeting process to work successfully within the public activity.  We have implemented a qualitative study within the two chosen municipalities. This case study is based on personal interviews that are conducted through semi structured questions.

Kalkbrottstvisten i Bunge Ducker : En ACF-analys av två kolliderande riksintressen

Abstract This thesis is based on a case study of the drawn out legal process on the question of establish a limestone quarry in Bunge Ducker in north Gotland (Sweden). The current fields are located next to areas that are protected by virtue of being EU-certified Natura 2000-areas. Despite this, the Swedish governments and courts have not agreed in witch national interest that should be prevail when decisions are made on this issue. This phenomenon are reflected in the judicial process and different court have evaluate information differently in the case. A change among governmental actors where priority is given to the importance of national interest have occur in the later part in the process.

BI M i förvaltningsskedet med avseende på konstruktion.

Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.

Gaming och informationsanvändning : En informationsvetenskaplig studie av tv-spel och gamers

The purpose of this bachelor?s thesis is to examine video games, gamers and gaming from an information science perspective. The purpose of the study is partly to study video games as a type of information system and partly to study gamers information use, information seeking and also the experience of gaming. A selection of five games have been analysed using a topology for video game analysis created by Espen Aarseth. A quantitative investigation has also been made, in the form of a web survey distributed through four Swedish online forums, the result of which was analysed using Carol Collier Kuhlthaus model of the information seeking process.

Vad vill du bli när du blir stor? : En studie om barns framtidsdrömmar ur ett genusperspektiv

The way towards an equal society, where both women and men has the same possibilities both private and in professional life, has been a long and still ongoing process. During my practical studies to become a recreation instructor I have noticed a difference between the children I have met in my workplace. What I saw was that girls and boys had a different approach towards their future, plus that the pedagogues at the school had different roles depending if they were men or women.In this study I have investigated which dreams and visions a group of after-school children has, plus how these distinguish between the genders. I have through group interviews, first three boys and then three girls, investigated how children look at their future focusing on career, spare time and familysituation. The questions have also focused on how children look at the schools pedagogues with gender as a premiss.My result shows that the children's vision on their future tends to look different between the genders.

Utveckling och konstruktion av dämpare och låssystem för vågkraftverk

The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.
