Digital dynamisk geometrisäkring : En kartläggning av dagens arbetssätt
Detta examensarbete innehåller en kartläggning av Scanias arbete med digital dynamisk geometrisäkring samt ett förslag på hur arbetet kan utvecklas.Kartläggningen skapar en översiktlig bild av hur dagens arbete utförs och beskriver de ingående delmomenten. Observationer av hur arbetet utförs har gjorts och dokumenterats och samtal med berörda personer på Scania har skapat förståelse för behovet av ett bättre och mer utvecklat arbetssätt.Scania vill bli bättre på digital dynamisk geometrisäkring för att kunna minska den idag relativt stora verksamheten med fysisk provning av prototypartiklar och färdiga bilar. Ett förslag till ett nytt arbetssätt har tagits fram och förutsättningar för detta har undersökts på företaget. Förslaget bygger på ett ökat samarbete mellan grupper med olika ansvarsområden kopplade till vilka krav som ställs på lastbilen. Utöver den rent organisatoriska delen innefattar det även mer handgripliga förslag på fortsatt arbete som bland annat behöver ett underlag i form av trovärdiga simuleringsmodeller.En jämförelse mellan resultaten från dagens simulering och fysisk provning har genomförts och resultatet visar att vidare arbete med förbättring av de digitala modellerna krävs innan det nya arbetssättet kan anammas tillfullo..
Att testa kvalitet : En validerande informationsinsamlingsmetod för ökad kunskapsåterföring
This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers. First a workplace analysis at Scania R&D is carried out to see how Powertrain Control Systems work and how they test their software. Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.

Controllerns roll i utvecklingsprojekt : Fallstudie hos Volvo CE och Scania CV
In order for companies to be competitive they perform different types of development projects. Due to globalization a greater focus is added on costs, not least on costs in development projects. Project controllers are involved in development projects in order to review the financial aspects. The authors have examined the role that project controllers hold in respect of two Swedish manufacturers, Volvo CE and Scania CV. The investigation has revolved around three main issues where the authors conducted interviews with controllers that do not work in development projects and project controllers in development projects. The goal of the interviews was to gain a greater understanding of the role of project controllers, how this role will differ from those that do not work in development projects and the difficulties faced by project controllers.
Gestaltningsförslag till ny förskola på Zakrisdal
Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.
LCC-analys av FTX-system : En jämförelse av centralt- och lägenhetsplacerat
This report is the result of a thesis conducted at the consulting firm Bjerking AB andis the final part of the Bachelor Programme in Construction Engineering at Universityof Uppsala. The work aims to investigate the costs and how the choice of ventilationsystem affects building projects during a long-term period. This report covers costssuch as investment, maintenance and energy but also how they affect residents andbuilders. Building regulations for energy consumption are expected to be tougher;therefore a comparison of two different heat recovery ventilation systems(HRV-system) was made. One system is based on a centrally placed unit that coversthe whole buildings ventilation through vertical shafts.
Ledarskap som drivkraft för dagligt lärande på arbetsplatsen
Det blir allt viktigare att som organisation skaffa sig hållbara verktyg i skapandet av ett dagligt lärande i syfte att ständigt förbättra och utveckla verksamheten för att kunna stärka sin konkurrenskraft. På senare år har chefsrollen alltmer kommit att handla om att leda och coacha sina medarbetare till lärande och utveckling. Syftet med denna studie var att, med utgångspunkt i en av Scanias fem ledarskapsprinciper ?Bygg kunnande genom kontinuerligt lärande?, undersöka hur första linjens chefer på Scania stimulerar dagligt lärande på arbetsplatsen. Tio semistrukturerade djupintervjuer genomfördes.
Godshantering med Scania Interactor
This thesis is about making a support for barcode readers and RFID readers on a computermounted in heavy vehicles. The computer has several applications designed for heavyvehicles such as an order handling application. The goal was to suggest an architecture toimplement a support for the readers. The architecture should be independent of whichmanufacturer who has made the reader hardware that was connected to the computer.At first a theoretically study was made around RFID technology and standards for thetransport and supply sector. Then the architecture was developed and a demo implementationwas made.The conclusion of this thesis is to implement support for barcode readers with a wedgeapplication.
Kiviksgraven : analys av dess historia och framtid sett utifrån bevaringsfrågor
This essay focuses upon the Kivik monument and its conservation difficulties, since its discovery at 1748 until modern time. The Kivik monument is found in southeast of Scania, and dated within the Bronze Age period. The perspective of the conservation on the monument has merely been on the monuments inner cist of stone and the rock carvings on the cist-slabs. When the monument was first archaeological examined at 1931, its sizeable cairn (75 m in diameter) had almost vanished and the cist was sheltered by a casing of concrete and metal roof. Between 1932 and 1933 the monument has undergone a large-scale restoration, and this criticized restoration resulted in a low antiquarian value with the responsible authority.
Anpassningar till standardisering inom Software Configuration Management : En fallstudie om standardisering inom mjukvarukonfigurationshantering
Change is inevitable when software is built and deployed. It?s not particularly problematic to manage change if there is just one system. But in a large global IT organization, with several systems and people who develop, problems may arise. If organizations don?t control change, change will control the organization.

Förbättrad saverringsdesign för dieselmotor
Vid drift av en dieselmotor skapas kontinuerligt små mängder avlagringar som sedan kan forma ett hårt lager kallat koks. Kokset bildas vid kontakt med heta ytor och ett sådant område är toppland, längst upp på utsidan av kolven. När lagret blir tillräckligt tjockt skrapar det insidan av cylindern vilket påverkar ytan negativt samtidigt som den blir ojämn. Oljeförbrukningen ökar dessutom, då den olja som finns på insidan av cylindern trycks uppåt och därmed förbränns i förbränningsrummet. För att få bukt med problemet har Scania infört en så kallad saverring.
Modellbibliotek över kylsystemskomponenter till Simulink
Scania är en välkänd tillverkare av tunga lastfordon och bussar. De profilerar sig som det presigefyllda valet med hög teknologinivå. För att kunna leda utvecklingen av nya funktioner och motorer måste många tester av alla system i dessa fordon göras. Till detta används provceller speciellt ordnade för specifika lastbilskomponenter och många av dessa komponenter behöver en yttre kylning under drift varför flera av provcellerna har reglerade kylsystem. Vid uppgradering av kylsystem eller nybyggnation av provceller med kylsystem finns en önskan att kunna simulera och göra tester av kylsystemet innan det faktiska kylsystemet finns på plats, för att säkerställa prestandan innan någon investering görs.
Merkostnader med vinterväghållning för Grot-transporter orsakade av väglagring.
Fuel wood is currently the third largest assortment from the forest in Sweden after pulpwood and lumber. Branches and tops i.e. logging residues are one of the assortments of fuel wood which is a common by-product after harvesting nowadays. The way to utilize, disintegrate and transport the logging residues varies between northern and southern Sweden. Branches and tops are collected throughout the year at appropriate stands, but are consumed mainly wintertime.
