This master thesis was performed at Scania Research & Development. The given mission was to see where the department Systems Development should focus to improve their development work. Thus the purpose was to map the product development processes in which the department works today and within them identify improvements. To fulfil the purpose a theoretical study of relevant terms, such as improvement work, product development and processes, initially was formed. The mapping method used is called "walk trough" and meant to let the people working in the processes be guides in their own process.

This is a qualitative case study about tourists and boat migrants in movement to and in place on the Canary Islands, Spain. The aim is to study how these two groups of guests are treated differently, either as guests or strangers, based on how they move, illegally or legally, where they come from and where they have rights to go. To analyze the case I use theories of how differences in ethnicity, culture and religion etc. are created and recreated in society in interactions among humans and in the politics - the politics of difference. The politics of difference creates and recreates categories of mobility such as tourists and boat migrants.

Cloud computing is a new buzzword within the IT-industry, and introduces a whole new way of working with IT. The technique delivers web based services, which results in that the user no longer needs to install an application locally on a computer. Since the application no longer needs to run on a local entity, but in a datacenter located on a service provider, the users no longer need any specific hardware more than a computer with an internet connection. Cloud computing also offers IT-infrastructure and development environments as services, these three service types is better known as cloud services. Through the usage of different types of cloud services, the need for maintenance and hardware is significantly reduced.

När Scanias maskiner som ska testa nya lastbilskomponenter eller hela lastbilar, så kallade testriggar, inte fungerar som de ska så fanns det i dagsläget en uppfattning att problemen i vissa fall dels var återkommande och dels var svåranalyserade. På grund av detta ville Scania Tekniskt Centrum (STC) införa rotorsaksanalyser av när testriggar inte fungerade som de skulle. Denna studie har undersökt vad som i dagsläget behövde förändras och vad som möjliggjorde att rotorsaksanalyser av fallerande hos testriggarna skulle fungera så bra som möjligt.En nulägesanalys gjordes. Resultaten av denna visade på att fyra roller fanns som var involverade i att åtgärda fel hos testriggarna, nämligen de som äger riggarna, de som arbetar med underhåll av riggarna, de som utvecklar riggarna och de som är ansvariga för arbetsmiljön och säkerheten hos riggarna. En process map skapades för att visa hur dessa roller i dagsläget samverkade för att bygga testriggar och åtgärda fel hos dem.Resultaten av nulägesanalysen visade på att fyra övergripande faktorer påverkade huruvida rotorsaksanalyser skulle kunna genomföras.

The present study examines the demolition of a house on Hammarkulletorget in 1996 and the discourse of Hammarkullen, Gothenburg(Sweden), drawn from the perspective of historicization [?historisering?]. I have examined how the past played role inpresentations of Hammarkullen and how the past affected the decision to demolish a house. By examining which role the neighbourhood?spast time played in the perception of the neighbourhood, the thesis aims at providing a better understanding of howthe past can influence and legitimize major changes in the urban environment.In the early 1980s the image of Hammarkullen as a victim of negative publicity is established and this reputation lives beyond thesimplistic and negative descriptions themselfs.

This master of science thesis is focusing on how the fault handling on hardware connected toa control unit on a Scania vehicle is working. To the hardware counts buttons levers, sensorsand CAN. The work has been concentrated upon how the fault handling is working and if it ispossible to find any new fault modes.The control unit that has been studied is called the Coordinator and is the core in Scanias threenetworks of control units. The Coordinators work is to transmit messages between the threenetworks and to process signals from buttons, levers and sensors. The values is then usedinternally or is sent to other control units on the CAN networks.

Detta examensarbete utfördes på uppdrag av avdelningen för insprutningsprestanda(NMCX) på Scania i Södertälje. Projektets huvudsyfte var att utveckla en provrigg för attstudera bränsleinjektorers prestanda. En ny testmetod existerar som ger noggrannaremätningar av multipla injektioner tack vare mindre oscillationer i mätmetoden som sådan.Mätmetoden ger möjligheten att utföra hål till hål?jämförelser av flödet genom hålen iinjektormunstycket.Baserat på mätmetoden omnämnd som impulsmetoden, utvecklades och tillverkades enprovrigg för flödesmätningar genom injektormunstycket. Målet med examensarbetet varmed detta att beskriva utvecklings? och konstruktionsarbetet av provriggen.

To be competitive in the corporate climate of today it is important to have effective logistic activities. A common resource within the internal logistics is forklift trucks, which are used to lift and transport material. It becomes more and more important to decide whether to buy, lease or rent the forklifts to obtain an optimal economic situation. Many companies have issues with internal pricing. It is difficult to price products and services correctly. It is common to price the overall instead of what it really costs.The purpose of the thesis is to present a model for the acquisition of forklifts for internal logistic operations, regarding financing and internal pricing, to obtain economic effectiveness and an optimal forklift fleet size. The study focused on a specific research question, and for this purpose interviews with experts were held, observations were made and a literature study was done.

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.

Syftet med denna uppsats är att bidra till en ökad förståelse för begreppet sponsringen genom att identifiera och analysera bakomliggande motiv till sponsring, faktorer som avgör val av sponsorobjekt samt om och hur sponsringen utvärderas. Studien genomfördes ur ett företagsperspektiv. Vår insamlade primärdata bygger på intervjuer med sponsoransvariga på Folksam, Svenska Spel och Scania.Metoden som tillämpades i uppsatsen bygger på Strauss & Corbins tankegångar kring grundad teori. Genom en interaktiv process av datainsamling och analys fick vi fram kategorier, relationer och olika mönster som vi förde ett resonemang kring.Resultat vi kan fastställa är att motiv och mål inte är exkluderande utan flera kan uppnås med en och samma sponsorsatsning. Varav sponsring kan beskrivas som ett verktyg med pluralistiska möjligheter.

This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.

We have been looking at three different types of agriculture in Södermanland, in the middle east of Sweden. We call the different types for Intensive, Extensive and Mix. The purpose is to get an economic defensible plan for how to run different farm sizes. We also have been looking at the working hours and how many hours the different types will give. We have a farm called Taxinge Gods as our pilot farm. Taxinge Gods grow 407 ha land and is located 60 km southwest from Stockholm.

Hur fungerar internrevisionen i aktiebolag noterade på Stockholmsbörsen för att förebygga ekonomisk brottslighet? Vilka skillnader finns mellan företag som enbart tillämpar Svensk kod för bolagsstyrning från de företag som också tillämpar Sarbanes-Oxley Act?Utifrån studiens frågeställning är huvudsyftet att beskriva hur internrevisionen motverkar ekonomisk brottslighet. Samt få en bild av internrevisionens variationer i de undersökta företagenStudien är utformad efter ett kvalitativt metod. Genom fyra intervjuer har ett empiriskt material samlats in. Det empiriska materialet tolkas senare i en analys och diskussion.

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.

The purpose of this work is to raise ideas and interest for land that is very much forgotten,unused and neglected in terms of maintenance and usability. Railroads are often seen as adirty and loud intrusion in the landscape and therefore cities turn their backs on them. Theland around railroads is not considered useful despite its often central location and scrublandis common in these areas.The starting point of this work is the restrictions and possibilities linked to the land withinthe security distance 30 meters from the railroad center. Within this security distance thereare numerous limitations and regulations due to the nature of railroad use. These limitationsare counted for in the initial chapter and lay the foundation for the rest of the work.
