CAP KC3-12 : Design and finite element analysis

In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.

Invandrarungdomar utan sysselsättning : en studie av arbetslösa invandrarungdomars attityd gentemot sig själva och den svenska arbetsmarknaden

The purpose of this study was to increase knowledge about what the lives of the unemployed youth of immigrant background looks like, and what the views of the unemployed young people are about work and employment. The study is a qualitative study where the empirical material is based on interviews with seven unemployed immigrant youth between the ages of 19 and 25 years. A study where the central questions was to explore how the informants' living conditions and identity are affected by being unemployed. The other issues aimed at how informants background affected their ability to enter the labour market, and the job expectations the informants had about the future and the Swedish labour market. Empirin have been analyzed with regard to methodology tool based theory, as well as theoretical starting points, such as social capital, formal and informal channels, ethnicity and stigma theory.

Viltanpassad röjning längs skogsbilvägar som en foderskapande åtgärd för älgen

The moose is a keystone species in the boreal forest ecosystem, but the dense Swedish population do cause some serious problems. From a forestry perspective, their browsing on young Scot pine (Pinus sylvestris) causes extensive losses of revenue. Adjusting the cleaning along roadsides of low trafficked forest roads can favour the production of plant species preferred by the moose. This is thought to redirect the moose´s browsing to the roadsides and thereby decrease the damages on commercial forest.The aim of this study has been to present a first evaluation of the vegetation in roadsides, one year after wildlife-adapted roadside clearing has been undertaken. In the wildlifeadapted clearing operation, the roadside was widened by removal of some trees in the forest edge whereupon a complementary clearing with a conventional chain flail was conducted.

Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi

The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.

Effektivisera materialflödet med hjälp av självgående truckar

The thesis that follows is performed in collaboration with Nitator in Oskarström.The factory in Oskarström focuses on laser cutting, robotic welding and surfacetreatment of steel for the automotive industry.The project aims to streamline the flow of materials in production by automatingthe movements of the forklifts, running to and from the interlayer, and betweenworkstations.The project started with a systematic literature search. The literature searchshowed the research position around the AGV-system. Also a review of studentliterature was made, so that a suitable method for practical implementation couldbe developed and applied. Selected method uses both quantitative and qualitativeapproaches, which is analyzed by using triangulation.The work has resulted in a modified layout of the current facility in Oskarströmthat can be used for the implementation of the AGV-system. It has also resulted inthe tender documents and profitability calculation from several of AGV-suppliers..

Helgonlika politiker och maktlösa arbetslösa : En undersökning av attityder och värderingar i politikers metaforer

Syftet med denna uppsats har varit att försöka besvara frågan: Vilka attityder och värderingar kommer till uttryck i Lars Ohlys respektive Göran Hägglunds användning av metaforer i debatten om arbetslöshetspolitiken? Jag har valt att studera de metaforer som förekommer när det gäller arbetslösa, arbetslöshet och den egna politiken i frågan. Jag har också analyserat de metaforer som används när de talar om/bemöter sina motståndare och deras politik. De artefakter jag har använt i min undersökning är två tal samt en TV-sänd partiledardebatt.Min ena hypotes var att det i talarens val av metaforer döljer sig attityder och värderingar som kanske inte syns vid ett oreflekterat mottagande av talarens budskap. Efter att ha studerat de båda partiledarnas val och användning av metaforer vill jag, till viss del,  påstå att en stor del av metaforerna öppet signalerar attityder och värderingar, inte minst när de tillskriver varandra negativa sådana.

Från trafiklärare till transportlärare

Abstract (in English)The purpose of this work is to find out what the driving instructor who currently works as a transport teachers feel about today´s driving education to transport high school to how it works at driving school. I describe in the study on how to become a transport teachers and on their everyday work. Even what others have written on this topic on driver training. I also interviewed four driving instructor who currently works as a transport teacher, about what they had for opinions on this issue. The method I have used myself of where unstructured questions to get so descriptive answers to questions as possible.

Kvalitetssäkring och processtyrningav ytstruktur på lackerat objekt

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Däck-mark Interaktion hos skogsmaskiner

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Förändrad aptering av massaved från 3- till 4-meterslängder vid gallring inom Södra : en systemanalys av effekter från avverkning till levererad virkesråvara

The costs of logging and of transportation with truck are dominating the total cost of wood delivered at industry. To support the profitability for the members' forestry the processing and handling with the timber has to be as efficient as possible. Increased length of pulpwood in thinning is one conduct that can result in higher productivity and/or lower costs. The study is scaled as a system analysis with the aim to exemplify the differences between working with 3- and 4-meter as standard length of pulpwood, related to biological aspects, timber receipts, cost of logging and cost of transportation with truck. Important aspects are if the change is technically and biologically feasible and economically profitable.

Från militärområde till stadspuls : Stadsdel Norr - en (nästan) vit fläck på Östersunds stadskarta

How can former military area I5 in Östersund, Sweden, evolve into Stadsdel Norr ("The Northern Quarter") ? an attractive part of the town center? In a theoretical part of the essay the significants of well functioning towns and streets are investigated. The history of Östersund and I5 is shortly reviewed. Present recommendations concerning city design are presented along with guidelines from Vägverket (National Road Administration) for urban streets. The conclusion reached is that a fundamental structure of streets and roads, public and private spaces, is crucial for the possible future development of an area.

Utvärdering av trafiksimuleringsmodellen RuTSim

Trafiksimulering är ett användbart verktyg då olika typer av vägar ska studeras. Statens väg och transportforskningsinstitut, VTI, har under de senaste åren utvecklat en ny landsvägssimuleringsmodell, Rural Road Traffic Simulator (RuTSim) (Tapani 2005). För att en simuleringsmodell ska vara användbar måste den ge en god överrensstämmelse mot verkligheten. Syftet med detta examensarbete är därför att utvärdera RuTSim, genom att kalibrera och validera två 2+1-vägar och en vanlig landsväg med mötande trafik. Detta både för en implementerad frifordonsmodell samt befintlig modell med trafikinteraktioner.

På väg mot en fri översättning ? eller bara på drift?

Denna uppsats analyserar ?det fria? i en översättning ? alltså de kriterier som utmärker en fri översättning. Dessutom analyseras texttrogenheten utifrån ekvivalensbegreppet.I detta syfte ligger tyngdpunkten på en analys av semantiska tillägg ochutelämningar i måltexten. Dessutom studeras översättning av engelska namn, talspråk, svordomar och metaforer, samt ändring av syntaxen i måltexten. Materialetbestår av de två svenska översättningarna av Jack Kerouacs roman On the road, nämligen På drift från 1959 och På väg från 2008, som jämförs med originaltextenoch med varandra.

Kurder och Identitetsbildning : En diskursanalys av kemalismen och PKK:s manifeste

The purpose of this thesis is to investigate the democratization process in Kurdistan on the basis of consolidation democracy with focus on arenas defined by Linz and Stepan (1997), namely economic, political, legal, civil society and arenas of state bureaucracy. Furthermore, I intend to explain Kurdistan?s road toward democratization in Kurdistan from 1991 until today, with a focus on the years 2003-2012. The main results are that Kurdistan has developed conditions that support a future consolidation of democracy. However, there are weaknesses in the economic situation, rule of law and the arena of bureaucracy.
