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.
Design och tillverkning av en stereoanläggning med aktivt delningsfilter
This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.
Utvärdering av en Magnetic Harmonic Traction Drive
In this report a new gear concept is evaluated using the magnetic finite element method (FEM)software MagNet and Ansys as well as the mechanical FEM software Abaqus. The gear conceptis evaluated in terms of maximum torque capability, torsional stiffness, gear ratio and efficiency.ABB Corporate Research has proposed a new gear concept which should be less expensive thangearboxes used today. The new concept is called aMagnetic Harmonic Traction Drive and usesthe principles of a harmonic drive gear to achieve a high reduction ratio. The gear conceptreplaces the wave generator used in traditional harmonic drives with magnets and uses tractioninstead of gear teeth to transfer the torque. The main components in the gearbox are the magnets,the flexspline, the magnetic portion and the circular spline.

The company is recommended to decide how the producthandling between operations should be performed as guidelines for the productionteam.
Har muren fallit? En studie av policynätverk inom infrastrukturprocessen i Skåne
The creation of Region Skåne, and the transfer of the development responsibility from the national administrative country board (Länsstyrelsen) has given the state new challenges. New structures have grown between Region and State, and also between different municipalities. These can be characterized as Policy-networks, and the goal of this study is to analyze the planning process of the regional infrastructure with these theories.This is a qualitative study of the infrastructure process in Skåne, and the actors that acts within this process. It has been studied with the eyes of the theories of Governance and Policy-networks. The main method to collect material has been through interviews with different actors within the process, and very little written material has been used.
Strängluftning av vallfoder : Inverkan på ensilagets torkningförlopp, spill och smörsyratillväxt
When harvesting ley you hope to get a fast drying and a faster harvest. If there is a
system with round bales, you need to have a dry matter close to 45 %. To make this as
fast as possible, there is made a machine which pick up the grass with an pick-up. It
turn the grass over and put it behind the machine (figure 2 and 4). There are few tests
to prove the efficiency of this machine.
Kreativitet i skolan : En kvalitativ studie om och på vilka sätt gymnasielärare upplever fenomenet kreativitet realiserbart i skolan
The students participating in my development work will work with a process book for handicraft studies. In the beginning of their studies, the students need practical knowledge about the development of the profession itself, but they also need to be challenged and learn how to solve problems on their own which will help them gain a deeper knowledge of the subject. I focus on open questions to create a process with the students. This process is created when working with Solution-Focused-Education. Through ?assessment for learning? we can help the students to improve their self-assessment and understanding of the learning process.
Digital Storytelling
The purpose of this paper is to analyze and map out the cyber culture of the Internet and its all users, identity, design theories and services. How people communicate and how they build up their identities are some of the baselines. I will also discuss the important aspects of Interaction design and how this can be used in a Community for digital storytelling.
The Internet, or new media, was founded in the 60?s by some great philosophers (McLuhan, Rheingold, Lambert and more). With influence from their books I will discuss and analyze what kind of media the Internet is and how it can be seen as extensions to our senses, as McLuhan claims.
Rekryteringsprocesser : Analys och betydelsen av rekryteringsprocesser

The purpose of this thesis is to do an analysis on three recruitment companies recruitment process and show the significance of the recruitment process for hiring the right person for the right position. The information for this paper has been collected through interviews and literature which concerns this subject.
Medborgarmedverkan i planerings- och designprocessen :
The theme of this thesis is citizen participation in the planning- and design process. It turns to everyone that studies landscape architecture or work as landscape architects and I hope that it can function as a ground for discussions as well as a source for inspiration.
Rågsved is a suburb south of Stockholm. Just outside the centre of this suburb, a small industrial area called Snösätra, is located. In a few years time the leaseholds for the small industries will expire and the key question is: What will happen then? This is my general concern and it was the main cause for me to start this particular work.
How do you attend to a place that appears like blank sheet of paper? To an empty page that can be filled with an infinite number of different formulations.
Värdeskapande i samband med förvärv: - om nyckelfaktorer i en förvärvsprocess
The acquisition process as an object for research and empirical studies have increased in importance during the past decade. The purpose of this thesis is to investigate this process further. This was done by reviewing previous research covering the area of mergers and acquisitions. Seven key factors that should be considered in an acquisition process emerged; acquisition project management, planning, communication between the acquirer and the potential target, goal alignment within management, company-cultures, a trade-off between a certain speed in integrating the companies and consideration of the employees, and finally the follow-up. These factors have been shown to increase the likelihood of value creation in acquisitions.
Tradarparet
Transportbranschen kan beskrivas som samhällets blodomlopp och vi är alla beroende av dess tjänster i vårt dagliga liv. Men denna bransch står inför stora utmaningar. Konkurrensen har drivits så långt att vissa aktörer bryter mot lagar och utnyttjar lågavlönad personal. Vilka är konsekvenserna av denna situation? Och vad kan man göra för att vända på denna trend? Sebastian Brännvall har utforskat hur man kan förpacka information så att denna sticker ut och väcker intresse hos en bredare massa.

Samhällskunskap och digitalteknik : Om undervisning i tre gymnasieklasser och dessanvändning av digital teknik
Syftet med uppsatsen är att bidra till ökad förståelse om samhällskunskapsundervisningens innehåll, genomförande och utformning på gymnasiet där digital teknik används.Fokus i uppsatsen har legat på att genom observationer och intervjuer i tre klasser och med de två lärare som undervisar klasserna få inblickar i hur lärare designar undervisning och hur elevrollen kan förstås när digital teknik används i ämnet samhällskunskap. Till hjälp för att analysera resultatet har analysmodellen Learning Design Sequence och i synnerhet begreppen lärsekvenser och iscensättning använts. Det senare begreppet syftar på faktorer såsom lärarnas arbetssätt och tillgängliga resurser som präglar en lärsekvens, vilket kan vara elevernas arbete med en uppgift för att nämna ett exempel.Resultatet visar att datorer och Internet ofta i någon form ingår i lärarnas design av undervisningen. Exempelvis har lärarna genomfört genomgångar med hjälp av Powerpointpresentationer samt utformat uppgifter där elever ska använda sig av sina datorer. I elevrollen ingår bland annat att vara dator- och Internetanvändare men också av att anteckna och lyssna.
