Varför är löven på våra träd gröna? Varför är blodet i våra vener rött? Alla dessa frågor kan besvaras genom att studera hur ljus växelverkar med atomer och molekyler. Atomer och molekyler absorberar ljus. Beroende på sammansättningen av atomer och molekyler så är det mer troligt att de absorberar ljus av vissa färger eller våglängder. Då atmosfären är uppbyggd av en viss sammansättning av molekThis thesis presents non-invasive spectroscopic studies of wood samples. Wood from both recent samples and archeological samples from the warships Vasa and Riksäpplet are studied. The samples are studied with an optical technique called GASMAS (GAs in Scattering Media Absorption Spectroscopy). The difference in absorption signals with regard to the orientation and number of annual rings in the woo

Att paketera svensk hälso- och sjukvård. Ömsesidighet, kapital, identitet och kultur i ett introduktionsprogram för utlandsutbildade läkare Utlandsutbildade läkare ( foreign-trained doctors, FTD) har blivit en allt viktigare tillgång inom svensk hälso- och sjukvård och bidrar till att minska läkarbristen. För att underlätta för FTD att komma in i hälso- och sjukvårdssystemet erbjuder Västra GötaWith a shortage of medical doctors, the functioning of the Swedish health care depends increasingly on recruitment of foreign-trained doctors (FTD). In order to facilitate the induction of FTD into the health care system, the Västra Götaland Region (VGR) in western Sweden offers a one-year induction programme, PLUS. The present research aims at examining dynamics in PLUS as an arena of meeting 

In laser wakefield acceleration (LWFA) a high intensity laser pulse is used to excite a plasma density wave with an associated electric field. This electric field can be used to accelerate electrons. However, to be accelerated the electrons first of all need to enter the plasma wave. This process is called injection. In this thesis a scheme for injecting electrons into a laser wakefield accelerato

A manual iterative process is often used in the design process of vehicle suspension systems. This thesis aim to develop a methodology for multidisciplinary optimization of vehicle suspension systems, which can be used to introduce an optimization driven process into the design process of vehicle suspension systems. A Multibody Dynamics (MBD) model of a Strut & Coil Spring suspension system w

The existence of systems has been essential in bringing order and providing benefits and security for people throughout the course of history. However there are cases wherein people have difficulties in adopting or conforming to systems. The aim of this study is to understand how systems that intend to be open encounter the paradox of excluding people in the process. The Public Transportation Age

Sammanfattning I detta examensarbete besvarar jag frågan om svenska domännamn har ett immaterialrättsligt skydd. Fråga är intressant av flera aspekter. Rättsområdet är relativt ungt och behovet av domännamn uppstod så sent som i början på 1980-talet. Det nya systemet att adressera datorer på Internet fick namnet Domain Name System (DNS). Utvecklingen och spridningen av Internet har sedan dess variSummary in English In my thesis I answer the question whether any intellectual property rights protect Swedish domain names. This question is interesting due to several aspects. The legal area is relatively young and the demand for domain names occurred as late as in the early 1980s. The new system to address computers on the Internet was named Domain Names System (DNS). The development and distri

En konkurrensklausul är en förpliktelse i konkurrensförebyggande syfte och är ofta förekommande vid företagsöverlåtelser. Vid företagsförvärv som innefattar goodwill och/eller know-how uppkommer ett behov för köparen att söka skydd mot att säljaren, med sitt försprång, efter förvärvet inte startar upp en ny konkurrerande verksamhet. Den rådande konkurrenssituationen kan vara en förutsättning för aA non-competition clause is an undertaking in competition prevention and is frequently used in a company transfers. In the case of company acquisitions that include goodwill and/or expertise, a need arises for the buyer to seek protection that the vendor, with its lead, does not start up a new, competing business after the acquisition. The current competitive situation may be a prerequisite for th

A number of different experiments on a dielectric elastomer, VHB 4910, were performed: uniaxial tensile strain tests, in situ SAXS/WAXS measurements of a sample under uniaxial tensile loading and DIC measurements of an electrically loaded circular sample with simultaneous force measurements around the circular boundary using a novel method developed in this thesis. The results are presented and an

Denna studie ämnar öka förståelsen för hur svenska universitet använder sökmotoroptimering i sitt arbete för att synliggöra information på webben. Studien ämnar även öka förståelsen för hur verksamma inom universitetsbranschen motiverar användningen av och målet med verktyget. Ett varumärkesperspektiv är allomfattande studien och härrör från en utveckling inom universitetsbranschen som genererat eThis study intends to increase the understanding of how Swedish universities use search engine optimization to create web visibility. The study also intends to increase the understanding of how employees in the university sector justify the use and aim of the tool. The research was conducted from a brand perspective, which has derived from the universities need of brand building. The data collecti

This thesis explores the data structure known as sparse voxel octree and how it can improve the performance of real-time ray tracing. While ray tracing is an excellent way of producing realistic effects in computer graphics it is also very computationally heavy. Its use in real-time applications such as games and simulators is therefore limited since the hardware must be able to render enough fram

Denna uppsats undersöker den ovillkorliga basinkomstens kostnad och finansieringsmöjligheter i dagslägets Sverige. Då utbetalningens nivå bör ligga minst vid existensminimum, fastställs hur stor denna summa kan tänkas vara, varefter förslagets totalkostnad beräknas. I uppsatsens huvuddel resoneras det sedan kring vilka av offentlig sektors utgiftsposter som kan ersättas av denna enda utbetalning,

In a society where more and more production becomes automated it demands robots that are as flexible and versatile as humans. Such flexibility demands automatic scheduling of tasks. In this thesis we approach the problem using Constraint Programming and through a case study we present a model for a dual-armed robot that is able to deal with a more flexible workload. We also introduce filters to cu

Habenulas roll vid kronisk smärta Kronisk smärta är ett stort folkhälsoproblem som drabbar ca 20 % av den Europeiska befolkningen. Trots denna höga prevalens är rådande kunskap bristfälligt och modern forskning inom fältet har inte kunnat uppvisa några speciellt åtråvärda resultat. Detta beror delvis på den stora komplexiteten inom smärtfältet, där känslor och andra kognitiva aspekter är en integ

A company is developing a new product for transporting temperature-sensitive liquids long distances. The new device will have an active cooling unit with very precise temperature regulation. This will increase the transportation time compared to conventional methods. This report will only concern the structural parts of the product, since development of the temperature control system has been done

My allotment got me thinking about what wonders nature does to man and our current stressful world we live in. How does the work environment look today and how can we arrange the office to find inspiration and an appetite for knowledge? This led me into the project ”The Working Scene”, the study of the working environments and how we can approve on the office. We are all in some way part of a glo

The main goal of this master thesis project was to take a manually controlled consumer quality quadrocopter and build the foundations which allows it to be autonomously controlled. This was achieved by introducing a exterior frame of reference through the use of a webcam coupled with image analysis algorithms. The position and rotation of the quadrocopter was identified, and several control struct

The Thesis provides an explorative insight into the topics of corporate sustainability, corporate environmental performance and corporate environmental disclosure. Broadly supported by literature review and literature references it contributes to theoretical understanding about how trust, culture, power and governance act as driving forces of corporate environmental performance, and as factors enc

One of the fundamental rights in the European Union is the Freedom of Movement of Persons. This right, that allows citizens of EU Member States to move and reside freely anywhere within the Union is not only a key factor for the European integration project, but is also of substantial economic importance. However, the actual experience of migrants moving within the European Union is not always as

This study looks at the effect international mining corporations have on local economic activity around gold mines in Burkina Faso. It also asks whether the mines have any additional effects, such as changes in poverty or inequality. The study does this by using remote sensing data, particularly nighttime lights, NDVI, and forest loss data to analyze the mine’s effect on the surrounding area. In a
