This thesis gives suggestions as to how to design a wooden-based wave-power buoy. The thesiswas carried out at Uppsala University in collaboration with the Division of Electricity and AppliedMechanical Engineering. The product was conceived and developed taking into consideration anumber of requirements put forward by the supervisor, Magnus Rahm. The most importantdemands were that the material used should be able to withstand pressure from the sea withoutbeing damaged and that the production costs should be low.Department of Engineering Sciences, Division of Electricity at Uppsala University was visitedseveral times to discuss issues including the various ideas with the supervisor Magnus Rahm, andwith several people in the department.The work started by studying available literature in order to get background information aboutsuitable methods available for the project and to see how similar projects were carried out. Thereason for this was to get a better understanding of this particular problem and how to solve it.After consulting the supervisor, the group decided to construct four different buoys using fourdifferent materials.

The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.

Outsourcing means to contract out work previously done within the cooperation to a supplier.This is an increasing trend today. Traditionally companies have outsourced manufacturing butwith the growing specialization they tend to outsource other activities as well.China?s economical reforms and entrance into the World Trade Organization, WTO, hasenabled international business connections. Since China offers one of the cheapest labours inthe world, many companies have an interest in starting up an activity in the country. Themany foreign investments in China have lead to an economical growth which in turn hasmade it possible for China to invest in the Chinese competence and innovative capacity.The commissioner of this master thesis, SMS, is one of the leading actors in retrieval ofamong other things mounts and stands for flat screens and projectors.

This thesis is performed as a summarizing project for the mechanical engineering education at School of Engineering in Jönköping. All knowledge necessary to complete this thesis was gathered from previous courses and education.This project was to develop a new product for the company TR Equipment AB in Tranås. The new product is going to be based on an already existing product, TR 1700. TR 1700 is a bathtub equipped with a height adjustable function. This product is used in retirement homes and in the care of disabled people.

Målsättningen med detta arbete är att ta fram en metod för att kartera och analysera den rumsliga variationen av landskapets sårbarhet för miljögifter, samt att visa hur geografiska informationssystem (GIS) kan underlätta denna rumsliga kartering och analys. Analysen utfördes inom vattenskyddsområdet Ignaberga-Hässleholm i Hässleholms kommun. Först studerades sårbarheten utifrån markens förutsättningar med hjälp av modellen DRASTIC och sedan studerades var de mest mobila bekämpningsmedlen har använts i förhållande till resultaten från DRASTIC..

The aim of this paper was to discover the functions and workings of personal networks and their advantages for self-employed sound designers and producers whose focus was upon the moving image (film, advertising, tv, etc). Investigations on how entrepreneurs develop their networks were made, as well as inquiries on how these networks are used for generating work. Another important aspect perused was whether or not the networks are dependent on specific geographical locations in order to function. A case study and comparative analysis was undertaken, based upon three qualitative interviews with entrepreneurs whose operations shared several similar characteristics. The results pointed out the importance of constantly making new contacts, and maintaining and managing current ones.

As to now, no study has been made of the mica tempered pottery found along side the asbestos tempered pottery in Norrland during the Bronze Age and Early Iron Age. Its occurrence has previously only briefly been noted in a few published works and the dating and geographical distribution of mica tempered pottery in the north of Sweden has to a large extent been unknown. This paper aims to compile the available information about this type of pottery and the locations where it has been discovered in order to date and explain the occurrence of mica tempered pottery in Norrland. It's also suggested that the occurrence of mica tempered pottery is connected to the spread of the early metalwork from the east to areas that today makes up the north of Norrland..

I Sverige genomförs varje år offentliga upphandlingar till ett värde av ca 500 miljarder kronor. Alla offentligt finansierade verksamheter måste följa lagen om offentlig upphandling och den formella upphandlingsprocess som lagen specificerar. Lagen är allmänt formulerad och anvisar en process där fokus ligger på förarbete och matematisk utvärdering.Cognitive Systems Engineering har vuxit fram utifrån insikten att effektiva processer kontinuerligt behöver använda såväl feedback och feedforward för att uppnå sina mål. Typiska tillämpningar är dynamiska, tätt kopplade processer där dessa behov är tydliga, men CSE som ramverk är generellt definierat och bör gälla även för en beslutsprocess på organisationsnivå. En CSE-analys har potential att förtydliga funktionella faktorer som tillåter upphandlare att genomföra effektiva och ändamålsenliga upphandlingar.I syftet att testa ovanstående hypotes genomfördes en fallstudie av Linköpings Universitets upphandling av företagshälsovård 2008.

This Master thesis has been carried out at Scania CV AB in Södertälje, in collaboration withKTH, The Royal Institute of Technology, Stockholm. The focus of this Master thesis isSetBased Concurrent Engineering(SBCE), with the purpose of answering the questions: what isSBCE, how does it work, and for what purposes is it applied.It was early established thatSBCE is often included as a part of Lean product development,which in its turn is often related to Toyota?s way of working. TheSBCE method includesworking with multiple solutions in parallel, eliminating weak alternatives throughout thewhole process. In opposite to a conventional product development process, where it iscommon one at an early stage tries to identify and choose the most promising alternative.Despite the appearance ofSBCE as a resource consuming method, figures from Toyotaindicates the opposite, thatSBCE is in fact a very effective way of working compared to othermore traditional methods.The process of this Master thesis was divided into three phases.

Villkoren i dagens samhälle förändras snabbt och miljön som beslutsfattare måste hantera blir allt mer komplex, detta samtidigt som tiden för att fatta beslut krymper. För att beslutsfattare ska klara detta kan de ta hjälp av verktyg. Vi har undersökt om geografiska informationssystem (GIS) är ett verktyg som effektiviserar framtagandet av ett beslutsunderlag när problemet är geografiskt relaterat. Undersökningen har genomförts som en fallstudie på fyra olika organisationer där vi jämfört processen vid skapandet av ett beslutsunderlag före och efter införandet av GIS i organisationen. Slutsatsen vi drar av vår undersökning är att geografiska informationssystem effektiviserar framtagandet av beslutsunderlag när problemet är geografiskt relaterat..

Detta examensarbete har utförts vid Duroc Engineering AB i Luleå. Duroc Engineering är Sveriges ledande företag inom laserförädling av metalliska ytor och levererar tjänster och produkter till framförallt gruv-, stål-, flyg- samt verkstadsindustrin. Rostervagnar transporterar kulor som används vid sintringen i Malmberget vid LKAB:s kulsinterverk. Genom att vagnarna passerar genom olika värmezoner sintras kulorna och vagnarna töms därefter för att hämta upp nya kulor. Detta pågår dygnet runt, året om, vilket medför stort slitage på vagnshjulen.

VSEM project and the need for a more efficient way of handling requirements andinformation are highly apparent.The overall objective of this thesis is divided into two parts:1. To identify criteria/factors leading to a successful introduction of an informationmanagement system.2. To develop an implementation process for a requirement management system ?the first step towards a PLM system in EE development at VCC.This will be done through interviews with employees, a literature review and an analysisof studies of three earlier projects within VCC.The conclusion of this study shows the great need for change in work methods fordesigners handling information and requirements. An implementation process has beenidentified with guidelines on how to handle different phases of the process.

Nano materials can today be found in a wide range of consumer products and the number of new products on the market is expected to inrease. In the shadow of hope for nano materilas potential in various applications, low awareness of its health and environmental risks is hiding. Furthermore, the knowledge about people´s risk perception of nano materials is limited. Parallel to the situation described above, the scholls meet the challenge of incrasing the scientific literacy. To achieve this goal, skills in argumentation in science studies has been emphasized and the concept of socio-scientific issues has been emerged.

BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).
