This thesis is closely related to the Dynamically Self-Configuring Automotive System(DySCAS) project. DySCAS is a middleware for electronics in an Automotive system. Thethesis work has been performed in cooperation with ENEA. Parts of the demonstrationplatform Self configurable High Availability and Policy based platform for Embeddedsystem (SHAPE) developed for the DySCAS project by ENEA have been used in theimplementation phase of this master thesis.The goal of this thesis was to evaluate how the Meteor MW, an offspring of the DySCASmiddleware, should handle QoS and to design a Quality of Service Manager (QoSM) for theMeteor MW that fulfilled hard real-time requirements. The thesis also had the objectiveof analysing and identifying the requirements on such a QoSM from a QoS perspective.Specifically the requirements to guarantee real-time support for applications running onthe MW.

This thesis deals with the development of a specification regarding a push-button, which will be used to control the gear-shifting function in an automobile. In addition to this the author will describe different techniques and theories that have been helpful in achieving data and results for the specification.Kongsberg Automotive AB, is located in Mullsjö, Sweden, the company supplies parts to the Automotive industry. In the research and development department, R&D, there is a group that works with development of Shift-By-Wire systems. In an automobile with a Shift-By-Wire system the communication between the gear-shifter and the gear-box occurs electronically. The mechanical link is, in most cases, taken away and replaced by the digital system.

This thesis was performed at Scania?s purchasing department of non-Automotive products inSödertälje, Sweden during spring 2007. The management of the purchasing department ofnon-Automotive products believe that their internal customers might not have fullunderstanding of what the purchasing department does. This is a problem because the internalcustomers might not use the contracts negotiated by the purchasing department or they mightnot involve the purchasing department when making purchases.The purpose of this thesis is to examine if and how the internal customers? perception deviatesfrom the purchasing department?s perception regarding the task of the purchasing department.And also to create a communication package with the purpose of increasing the internalcustomers understanding of what the purchasing department does.

Att arbeta med Lean innebär ett långsiktigt tänkande i en kultur som präglas av respekt för människan och för att ständigt minska mängden slöseri, Muda, med hjälp av ständiga förbättringar, Kaizen. Detta kan sägas vara en sammanfattning av Leanfilosofin. Med insikten om att Leanfilosofin är grundläggande för en lyckad implementering av Lean, sattes syftet med detta arbete: Att få in Lean i blodet hos personalen vid Kongsberg Automotive. En strategi utformades kring lärande för att nå en gemensam förståelse, en plattform, som ska finnas till grund för ett långsiktigt arbete med Lean. Strategin är uppbyggd efter teorin om Lean och den process man genomgår i ett lärande.

This thesis is developed by Posten Åland AB in order to simplify the work of agency staff when distributing mail in rural areas. In my thesis I have developed an application to help Automotive mail dispensers. The need for such an application exists, especially during the summer but at other times when ordinary dividend cannot run his route. With the help of a PDA and a GPS the mail dispenser should see where the next stop is and what is to be delivered thereThere already was a directory of mailboxes and the addressees and the coordinates of the mailboxes. Using this, I will implement functionality to retrieve a specific route and plot those coordinates on the map..

The disconnect between assumptions regarding computer users interactions made by software engineers and the actual interactions do, for various reasons, not always match. Gathering actual usage data from user interfaces can enable software designers to make better educated decisions. By buildning a prototype for collecting such data from a diagnosis tool for the Automotive industry this project has shown not only how to benefit from the data but also how to perform the work. The data is 1 600 sessions consisting of 26 000 individual events. From this it has shown that available tools can assist in rudimentary questions regarding usage.

This thesis is a part of the DySCAS (Dynamically Self-Configuring Automotive System)project which has the overall purpose of creating a middleware for the electronics in an Automotive environment. The thesis has been made with collaboration with ENEA AB who is a member of the DySCAS project. ENEA AB has developed a demonstration platform to test the fundamental ideas which the DySCAS project is built on.The purpose of this thesis was to design and implement a GPS application to be added to the demonstration platform. This was done by adding a GPS receiver to the original DySCAS demonstration platform and designing and implementing an application to be able to extract the information from it. The resulting application is able to present cur- rent position and absolute time to the DySCAS networks as services to be used by other applications or by the network it self.

The Automotive industry is increasingly studying lightweight solution in their designs, also rational production and low costs in materials and manufacturing methods are of great interest. This thesis consisted in the practical evaluation of anchors for sandwich panels. The object was to study loads of shearing and pull out of the plane. The experiments were carried out on panels made up of 1mm aluminium coatings and 50mm extruded polystyrene (XPS) at its core. As the fasteners used simple methods such as blind rivets, screw and glue.

Background: The literature concerning M&A has thus far concentrated on the merging companies, and on what kind of effects an acquisition has on these companies. The effects on the involved companies´ (customers and) suppliers have largely been ignored in the M & A literature. Purpose: The purpose of this paper is to describe and analyse how the suppliers relationships to the aquired company are influenced by an acquisition and how the suppliers handle the following situation. Method: The paper has been carried out in the form of a case-study and we have interviewed some suppliers to the Automotive industry. Results: The full effect on the suppliers relationships to Volvo has not been seen yet, due to the fact that only two years has passed since the acquisition and that the current products have a lifecycle of 3-5 years.

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..

In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.

This report includes both direct (liquefied petroleum gas and diesel) and indirect (water, process-water, long distance heating, waste) emissions from their company.

En vanligt förekommande laminering är polyuretanskum, som används för att ge egenskaper som mjukhet, komfort och flexibilitet till textiler. Ett användningsområde som tillverkaren och leverantören Borgstena Group Sweden AB använder polyuretan till är lastbilars väggpaneler. De vill dock ersätta den polyuretanskumlaminerade dubbeljerseytrikån som används idag med endast en ren trikåkonstruktion för att slippa problem som dellaminering och minskade töjegenskaper. Dessutom så har den kemiska sammansättningen av polyuretan som används i lamineringen visat sig vara belastande för både miljö och människor. I denna rapport klargörs varför polyuretanskum behöver ersättas och vilka möjligheter som finns i dagsläget för att göra detta.
