Broms- och styrsystem för möbeljalusier
This report is the result of a master thesis at the Department of Mechanical Engineering, Division of Industrial and Economical Development, at Linköping University of Technology. The project was carried out on behalf of Fanerami AB, Mjölby and includes 20 weeks of full time schedule work.Cabinets with vertical mounted roller shutters all share the same problem, namely weight balancing. A roller shutter has an equilibrium area where the sum of the different forces acting on the shutter equals zero. As the shutter leaves that area it will pick up speed as it falls towards the bottom. When the shutter hits the bottom of the cabinet there is a potential risk of getting fingers caught and in this project a solution to prevent this from happening was to be presented.In this project, three concepts have been generated with the following different purposes:?In concept 1 the risk of getting any fingers caught when the shutter closes was to be eliminated in an efficient and inexpensive way.?In concept 2 the roller shutter had to be balanced at all time providing the possibility to keep the cabinet open in any position.?The last and most challenging task was to create a remote controlled TV cabinet.
Enzymatisk modifiering av fiskolja - jämförelse mellan olika lipaser
Enzymatisk modifiering av fiskolja - jämförelse mellan olika lipaser.I detta arbete studerades tre olika lipaser som katalyserade en metanolysreaktion i fiskolja.Målet med arbetet var att finna ett specifikt lipas för produktion av en EPA/DHA fraktioner från fiskoljan i en metanolysreaktion få högt utbyte av Sn-2 monoglycerider av EPA och/eller DHA och med detta kunna möjliggöra uppkoncentrering av hälsoviktiga fettsyror jämföra reaktionen i normal och superkritisk atmosfär.Metanolysen ägde rum i normal och superkritisk atmosfär genom att oljan, enzymet och metanol blandades i respektive reaktorn.Sn-1,3 specifika lipaser var isolerade från Thermomyces lanuginosa (Lipozym TL IM från Novozymes, Danmark) och Rhizomucor miehei (Lypozym RM IM från Novozymes, Danmark ) och ospecifik lipas från Pseudamonas sp.(Amano-C från Amano Enzyme Inc. Japan). Alla enzymer var immobiliserade på jonbytare.I försöken användes ?Ledins? fiskolja som var köpt i en lokal affär. Oljan var en blandning extraherad från oceanernas olika fiskklasser.
Implementering av Virtual Design and Construction: en
fallstudie av Veidekke Entreprenad AB
Den svenska byggbranschen står i nuläget inför en stor teknisk förändring, införandet av Bygg-informationsmodeller(BIM)/Virtual Design and Construction (VDC) i stor skala. Branschens olika aktörer ser olika vinster med implementeringen som kommer påverka hela byggprocessen, från projektering till förvaltning. Denna studie fokuserar på organisation och process i projekteringsskedet och grundar sig på en fallstudie av Veidekke Entreprenad AB. Företaget har implementerat VDC i delar av organisationen och i nuläget, efter lyckade pilotprojekt, utvidgas satsningen och implementering görs i större skala. Studiens syfte är att kartlägga Veidekkes VDC-mål och strategier, för att därefter studera process och organisation i projekteringsfasen och hur de bör utvecklas för att skapa goda förutsättningar för att VDC-målen ska kunna uppfyllas.

Skarven : ? Produktutveckling av en oljedimavskiljare
This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.
Förändrad interaktion, förändrat värde? : En kvalitativ studie om värdeskapande vid mänsklig och teknisk interaktion
The progress in the field of technology is often described as massive and its development has had a great impact on the social development (Vetenskapsrådet, 2012). As a result of the digital evolution, there has been a change in the way customer and company interact (Normann, 2011). The traditional way for players to interact with each other required an interaction human to human (ibid), a mode of interaction that now can be replaced or supplemented by todays technology and often Internet-based solutions (Salomonson et al., 2013). These technological solutions, the technical interaction, are often referred to as self-service systems. These systems enables the customer to carry out the tasks previously performed by the company (Hilton and Hughes, 2013).
Kulturen och kapitalet Hur, vad och varför ett antal män läser
This thesis deals with the leisure-time reading of fourteen men with two different occupations, teachers of technology and directors of companies. The main reasons for writing the thesis are that very little is written about mens reading habits and also statistics that tell that mens reading decline regardless of educational level. The purpose has been to compare the reading and relations to literature between the two groups of men and to find out if any differences have to do with factors such as social background or age. The questions we have asked our collected data has been what, how and why the men read. We have tried not to investigate the work-related reading although we are aware of the difficulty in separating this from the leisure-time reading.
Layoutförändring på SCA Förpackningsservice Värnamo
Fabriken vid SCA Packaging Förpackningsservice i Värnamo har under en längre tid haft en layout som inte har varit ändamalsenlig till dess funktion. För att kunna möta ökad konkurrens och interna krav pa effektivisering behövdes en ny lösning för maskinuppställning och flödeshantering.1 oktober 2005 inleddes examensarbetet vid SCA i Värnamo, då det hade beslutats att en limmaskin skulle flyttas in i de redan trångbodda lokalerna. Examensarbetarna fick i uppgift att, med gängse metoder, ta fram en ny layout som dels var möjlig ur ett rent praktiskt perspektiv, och dels sa effektiv att den nya maskinen kunde installeras utan att nyanställningar skulle behövas göras.1 inledningsfasen gjordes en flödeskartläggning av produktionen vid företaget med hjälp av de produktionskort som används i tillverkningen. Denna flödesanalys låg senare till grund för hur den nya layouten utformades. Med metoden systematisk lokalplanläggning arbetades en ny maskinuppställning fram.

Ledarskapsprogram för innovation
Since the 28thof May the project to develop an internal Innovation Leadership Program (ILP)on Accenture has been running and came to an end in November the same year. The taskwas formed into a master thesis and given to two students at the Royal Institute ofTechnology in Sweden.Since the start the content and structure of the ILP has been established based on the resultsof a theoretical study, a gap analysis and an external and internal benchmarking. The theoreticalstudy focused on articles, books and lectures about innovation, creativity and pedagogy. Subjectssuch as leadership, motivation, reflection and coaching were studied as well, but in a smaller scale.The gap analysis consisted of eleven interviews with people from different career levels withinAccenture and the goal was to establish the view of innovation and creativity among the employees.The interviews also asked about the knowledge the participants had about Technology Lab in orderto get insight of how to improve their communication and cooperation with people in client projects.Internally a similar program was studied called Minority Leadership program, whom will not bedescribed further in this report, to get inspiration. The external benchmarking was conducted onStanford and was very successful.

ANVÄNDNING AV PRODUTIVITETSVERKTYG FÖR ATT NÅ UPPSATTA PROJEKTMÅL : En undersökning på ett Skanska projekt
This is a result of a diploma work in construction engineering. The purpose of this thesis is to investigate the nature of the productivity in a given project and how the Skanska productivity tools were used in this project.Interviews were held among workers and management to get some answers on what affected the work and its productivity. The result of the thesis showed that the productivity tools as propulsion analysis and ?goal cards?, were not used to a wide extent in this project. Furthermore there was almost no feedback for the one who made the calculation and the offer for the project, which might affect the results on projects negatively in the future.Within the project there was a lot of waiting time which affected the productivity.

Rum för musik på biblioteket: En fallstudie av Bibliotek 10 i Helsingfors
The aim of this master's thesis is to study how the design of the music library space affects how it is used and its role as an arena for culture. This is done in form of a case study of Library 10 in Helsinki, a public library branch that specializes in music and information technology. The backdrop to the study is the changing context for cultural activity in the information society and the role of public libraries as public space and meeting place. By analyzing the distribution of space in the library, the distribution of functions and artefacts and the spatial use of the room, I interpret the ways in which this distributional logic produces a unique place for music and culture. I discuss the music library design in a space and place perspective, utilizing theoretical tools from cultural geography and the space theories of Henri Lefebvre.
