Flexibla fixturer i bearbetande maskiner
This thesis was conducted at Linköping University and Saab Aerostructures DPS, Linköping, and focuses on the possibilities of flexible fixturing in machining applications. The thesis is part of the research project "Koofix", which is collaboration between Linköping University and a number of companies.The thesis is aimed towards small batch production which, for Saab Aerostructures DPS, means diverse part geometry and that parts are manufactured in very small numbers, sometimes just one piece. The result of this is that expensive dedicated fixtures are made for most parts. By introducing more flexible fixturing methods to this kind of production the cost of fixtures and tooling will be reduced, and make the production more efficient.New flexible fixturing methods has been presented and evaluated through the thesis, which has resulted in three different concepts. These concepts have been the result of literature screening and study of current manufacturing process at Saab Aerostructures DPS.

Att rädda det förgångna : Om Walter Benjamins historiska materialism
The present essay concerns Walter Benjamin?s thought regarding history and temporality as he articulated it in his last work that was only published posthumously: ?U?ber den Begriff der Geschichte?. The purpose is to analyze Benjamin?s construction of historical materialism and to suggest a reading of it as directed towards an opening of history. For Walter Benjamin, every moment presents itself as a possibility of radical otherness: a possibility for things to be different.
Laserinkopplingselement För XFEL Laser Heater : Från Idé Till Färdig Produkt I Designstadie
Uppsala University is involved in a large international collaborationto build the Laser heater system for the European Xray Free-electronlaser in Hamburg, Germany. In this thesis I describe a laser incouplingdevice into the vacuum chamber of this laser heater all the way fromthe specifications to a completed design.The laser heater is a very important part of the XFEL and thepart described here is a part of the vacuum system needed to couplean external laser into the electron vacuum system and align it withthe electron bunches in order to heat them. The task was started by studying the literature about the basic theory andthe design of vacuum systems. After this study and collection of ideaswith colleagues I started to prepare different concepts to solve thetask. The ideas can be put into two categories, in one case the couplingmirror is located inside the vacuum chamber and in the second caseoutside.
Exil hederskultur-ett narrativ
Drawing on a broad theoretical framework that includes theories about globalisation and honourculture, this thesis aim is to demonstrate that globalisation and honourculture, constitute a conceptual network, i.e a structural relational matrix in which concepts are embedded. Being part of conceptual network, these concepts are related to each other ontologically. The idea of conceptual network, and the thesis as a whole, draw upon what has been called ?relational perspective?This study aims to show the impact of globalisation on honourculture. The study shows the importance of narrative in the construction of discursive boundaries.
Samhällets syn på fattigdom : En jämförelse av begreppen "nödtorftig vård" och "skälig levnadsnivå"
The purpose of this bachelor's thesis in social work has been to examine whether society's perception of poverty and poor people has changed over the more than 160 years have passed since the first national Poor regulation was enacted in Sweden. With a social constructionist approach and inspired by the critical discourse analysis we have conducted two studies to find answers to what differences and similarities between the concepts of scanty care (1847) and standards of living (2002). A study based on previous research was conducted to examine how society's perception of poverty has changed and designed in a historical perspective. We also conducted a textual analysis of relevant legal texts and legislative history to show how these texts reflect the society's official view of poverty based interventions targeted to poor people.The two sub-studies show that the concepts at different times in history has been crucial for the community support poor people were entitled to. Our overall conclusion is that despite today's advanced social policy there are many obvious similarities between the concepts of scanty care and standards of living.

Motivation ur ett elevperspektiv : En studie om vilka faktorer som har betydelse för elevers motivation
AbstractThis study deals with motivation as an overall concept, from a student perspective. It encompasses factors that could directly affect students and their positive or negative motivation, concepts such as relationships, communication, expectations and interactions and their importance to my informants.The study also discusses certain theories to show the different ways of defining motivation, specifically in relation to my informants and their and my conclusions. My ambition is to establish the importance of the concepts mentioned above, as well as perspective changes to the enhancement of the performance standards of a good teacher.The purpose of this work is to describe, understand and clarify the external and internal factors that affect motivation. In order to achieve this purpose, I chose to use a method of qualitative interviews with three students, with different backgrounds, schools and conditions but with a lack of motivation as a unifying characteristic. The research questions were as follows:What factors influence students' motivation? What impact do achievement targets have in relation to the pupils? own motivation to learn?How important are teachers' expectations for the individual student's motivation?Within this study sub-concepts such as importance of expectations, relationships, and significant others are, according to my analysis, of great importance.

Anva?ndarbehov i samha?llsplanering : en fallstudie av anva?ndarcentrerade metoder
Public participation in urban planning is meant to increase democracy in the planning process. Even though all citizens have the option to participate in urban planning debates, few seize their chance to partake. This thesis describes a study on how user needs are met and prioritized in design processes concerning urban planning. The aim was to determine whether user-centered design (UCD) methods could be used as an avenue for public participation in urban planning and ultimately invite more citizens into the planning process.The thesis details a design process where a team worked to develop Farsta, a suburb of Stockholm. The design problem was the question of how Farsta could become an attractive business location.
Utveckling av nytt koncept för positioneringsslid
A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.
