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.

Inaktivitet har blivit ett stort problem i dagens stillasittande samhälle och stor vikt läggs på de intellektuella färdigheterna. Konditionsträningens positiva påverkan på de kognitiva funktionerna har under de senaste åren studerats och resulterat i ett flertal artiklar rörande ämnet. Den forskning som bedrivits har undersökt den kortsiktiga påverkan av kognitionen. Syftet med denna studie var att undersöka den omedelbara påverkan på de kognitiva funktionerna: resonemang, koncentration och uppmärksamhet efter högintensiv konditionsträning samt se om en ökad kondition förbättrade kognitionen hos friska unga vuxna. Syftet med undersökningen uppnåddes genom en kvantitativ single system experimental design studie där författarna gick in som deltagare.

The purpose of this thesis is to examine how key performance indicators are being used as performance management tools within the production industry. Specifically the purpose is to investigate how the KPI:s within the telecommunications industry drives reusability regarding production test systems. This thesis will also highlight today?s cost models and suggest improvements of the KPI and what new ones could be introduced. A case study at Ericsson AB has been performed.

Ett effektivt användande av ett informationssystem förbättrar informationshanteringen inom en verksamhet. För att ett informationssystem ska kunna fungera effektivt krävs att det motsvarar de krav som ställts på informationssystemet av olika intressenter.Requirements Engineering (RE) är en viktig del av systemutvecklingsprocessen för att kunna säkerställa en väl fungerande kravhantering. Use case är en teknik som kan användas som hjälpmedel i RE-processen för att identifiera och dokumentera krav.Syftet med detta examensarbete är att undersöka om use case är tillräcklig som enda teknik för att identifiera och dokumentera krav samt vilka eventuella kompletterande tekniker som används bland systemutvecklare. Resultatet av undersökningen visar att use case-tekniken inte är tillräcklig utan måste kompletteras med andra tekniker för att möjliggöra att samtliga krav kan identifieras och dokumenteras..

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

In the social sciences, geopolitical theory is used in order to analyze states actions and commitments when it comes to foreign policy. This thesis develops a new understanding of geopolitical theory. Firstly, the development and application of geopolitical theory, from its foundations in the early twentieth century to contemporary geopolitical studies is discussed. Secondly a revised understanding of the variables integrated in the concept and how it can be operationalized as an analytical tool is presented and tested empirically.The critical assessment of the research field of geopolitical theory tells us that six different geopolitical perspectives have been considered the most influential (room, strategy, power projection, identity, affiliation and governance) when it comes to analyzing state action. This model is applied as an analytical tool and thus tested on a single case.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

This thesis investigates the communicative role of scenography in the performing arts for children, with an aim to make the readers understand the ways in which a set design can be optimized so that a young audience can be able to interpret the play and its message.The art of scenography is complex and includes many elements. The research questions can therefore be grouped into three clusters: one artistic oriented (How does the scenographic process work and what is its relation to the scenic piece at large? In which ways may scenography be used to support the desiderate interpretation?), one audience oriented (Which work processes enhances the chances of creating dramatic art that is perceived as meaningful to the audience? On what premises can the semiotics of theatre be used in the performing arts for a young audience?) and last a cluster that focuses on Den magiska cirkeln (The Magic Circle) by ung scen/öst (What is told in the show and how is this portrayed in the scenography? Who is in the target group, and does the audience get the feeling of the performance as intended?).Den magiska cirkeln is used as a case study in the thesis in order to reflect the theoretical material. Methods in the case study includes performance analysis, a survey completed by 178 people in the audience and an interview with scenographer Anna Dolata. 14 performing analyzes of Swedish children?s theatre shows have been made in addition to the case study.The thesis analyses and compares two work logics; the internal logic and the external logic, and it is shown that meaningful interpretations are likelier to happen with an external logical point of view.

AbstractPurpose ? The purpose of this study is to examine the challenges that exist within thematerial handling process, to and from a department for service and maintenance at a hospital, and how the challenges can be managed to achieve a more efficient material handling process. In order to fulfill the purpose the following two questions where formulated:1.

This account deals with my degree in furniture design. The project was done in collaboration with the architect firm Byggnadskonst AB in a quest for the cafe chain "Vivels"Byggnadskonst AB?s mission was to make the interior of the cafe that Vivels is building in Larsberg Center on Lidingö. My assignment was to design chairs for the café. In the beginning I had even thought about designing a table, but as time past I focussed more and more on the chairs.

Graphic design is an integrated part of the public spaces we move through in our daily lives. This thesis explores the emotional aspects of graphic design, with a focus on environmental graphics for the public space. The goal is to find ways in which the emotional aspects of a design solution can be varied without compromising the practical aspects, i.e. affect the conveyance of information. This goal is pursued through an analysis of historical and contemporary literature as well as by design practise.

The aim of this study was to understand how evaluations are implemented and used in procured nursing homes for elderly. Our methodological approach consisted of a single-case study research. The case in this study was Växjö municipality. Three procured nursing homes for elderly were chosen in the municipality as examples of implementation and use of evaluation. The method for retrieving empirical data and the analyzing of it was based on triangulation.

New technologies and new consumer behaviors are having a large impact on mediacompanies. The biggest change is in the behavior of the younger demographic whereold platforms like television are abandoned for new online platforms. In this newworld, media companies and organizations need new tools and business models tostay competitive. One such tool is Design Thinking, a term used to describe a cognitivedesign-specific set of activities used during a design process. It has been popularizedin commercial areas and there the term is used to describe an applicable workflowused to promote the skills required to use Design Thinking.
