Att samhällets medborgare är välunderrättade är en grundförutsättning för att demokratin skall vara fungerande och med anledning av det spelar den nyhetsförmedlande journalistiken en viktig demokratisk roll. Idag finns information och nyheter att tillgå nästan var som helst och när som helst, via Internet i datorer och mobiltelefoner samt i radio och tidningar eftersom samtliga nyhetsmedier har gått från att vara hushållsbundna till att konsumeras utanför hushållet i allt större utsträckning. Syftet med den studien är att ta reda på vad tittaren verkligen minns direkt efter en Tv-sänd nyhetssändning och om det i huvudsak är någon särskild typ av nyhet som gemensamt fångar tittarna. Genom att använda en fokusgrupp som metod har jag kunnat se en klar tendens och dra en tydlig slutsats för ett resultat av att det är få nyheter, sett till antalet, som tittaren minns efter en nyhetssändning är det är ytterst begränsat antal detaljer och citat som kan kommas ihåg..

Studien behandlar ämnet fri programvara utifrån ett diskursanalytiskt perspektiv. Texter och tal av Richard M.Stallman, grundaren av Free Software Foundation (FSF), ligger i fokus för studien. FSF är en rörelse som har isyfte att göra och kämpa för fri programvara. Detta innebär uttryckligen en kritik mot programvara som är ofrieller proprietär. Studien visar på tre olika diskurser som är betydelsefulla för fri programvara; frihetsdiskursen,maktdiskursen och etikdiskursen.

Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.

The aim with this thesis is to investigate two different methods used to test usability on web-sites to determine the advantages and disadvantages of two methods and compare the results. The two selected methods are the think aloud method and asynchronous remote method. Re-mote usability testing has existed for more than ten years but the possibilities with this meth-od needs to be explored more.To achieve the purpose of this thesis a case study was conducted on an e-commerce site and for the online remote usability testing software was used.The results of this study show that think aloud usability testing encounter more issues with the website than the remote usability testing..

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.

The usage of Unmanned Aerial Vehicles (UAV) for several applications has in-creased during the past years. One of the possible applications are aerial imagecapturing for detection and surveillance purposes. In order to make the captur-ing process more efficient, multiple, cameraequipped UAV:s could fly in a for-mation and as a result cover a larger area. To be able to receive several imagesequences and stitch those together, resulting in a panoramavideo, a softwareapplication has been developed and tested for this purpose.All functionality are developed in the language C++ by using the software li-brary OpenCV. All implementations of different techniques and methods hasbeen done as generic as possible to be able to add functionality in the future.Common methods in computervision and object recognition such as SIFT, SURF and RANSAC have been tested..

The purpose of this paper is to examine the ancient library organisation in the Mediterranean area. The focus of the study is if they used catalogues, marked their material and their methods for shelving. During the ancient period the people used to write on clay tablets, parchment- or papyrusrolls and codex, which was significant for the organisation. The method, which I use, for the examination is based on criticism of the sources, how the modern scholars has interpreted ancient remains and texts. The study shows that the first evidence for library organisation is from Mesopotamia 2350 BC.

Det har under lång tid existerat en diskussion gällande huruvida det finns en formel för att skriva musik som tilltalar alla. I detta arbete gjordes ett försök att ta reda på om så är fallet. Detta gjordes genom att analysera tio listettor från Trackslistan och identifiera gemensamma nämnare såsom form, tempo, tonart, instrumentsättning och ackordföljd. Med hjälp av de gemensamma nämnarna skapades en idealform som borde tilltala flertalet lyssnare. En låt komponerades efter idealformen, och jämfördes i lyssningstest med andra variationer på låten för att se om försökspersonerna föredrog idealformen.

This report describes the manufacture and control of a flying platform. The report describes the basic and fundamental theories required to get the platform flying. It touches on subjects such as A/D-conversion. PWM-control and PID-control. The sensors used in the platform are a gyro and an accelerometer.

The creation of value is considered the core purpose and central process of economic exchange. Value creation is now conceptualized as shared by both producers and customers, and value is seen as fundamentally derived and determined in use, the integration and application of resources in a specific context, rather than in exchange, embedded in products and manifested as price. The field of research is abundant with publications but these do not fully further the understanding of value creation and co-creation in a way that is meaningful for theoretical development and decision making in business and marketing practise. Without a thorough understanding of the factors characterising value co-creation, the nature as well as content and locus of co-creation cannot be identified. In that case value co-creation easily becomes a concept without substance. Until now, individual publications on co-creation have focused on few or different aspects, have emphasized the process from either the customer?s or from  the firm?s vantage point, have different theoretical approaches and have ignored the complexity in interactions between actors.The purpose of this essay is to analyse how five fundamental aspects of co-creation of customer value are perceived in contemporary marketing literature. Discussing the different views on co-creation, this essay concludes that thoughthere are evident points of agreement, finding one generally valid doctrine of predestination or value co-creation is improbable.

This essay examines the European Union?s (EU) ability to play a leading role as a global actor on the world stage in international relations. Specifically, this essay studies the EU?s role of negotiator in the UN Climate Change Conference in Copenhagen in December 2009.  This essay also analyzes explanations for this role. Research is based on case studies, with conclusions drawn using an inductive approach.

Dialekter av olika slag är något som de flesta kommer i kontakt med dagligen, genom möten, via TV eller radio och även i skolan. I denna uppsats undersöks hur dialektundervisningen ser ut i skolan och hur stort utrymme momentet får. Detta görs med hjälp av en enkätundersökning som sammanlagt 34 informanter i Karlstad, Södertälje och Umeå fyllt i. Dessutom analyseras dialektavsnittets utrymme i elva läroböcker för kursen Svenska 1, för att jämföras med undervisningen.     Resultatet visar att lärarna i snitt undervisar 5,27 lektioner om dialekter, där lärarna i Södertälje uppgett minst antal lektioner. Vidare visar undersökningen att flera faktorer påverkar hur stort utrymme momentet får, bland annat hur pass intresserade eleverna är av dialekter.

The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.
