This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.

The aim of the thesis is to highlight external factors to explain why the EMU was created. The external factor considered here is the monetary policy of the United States, which often conflicted with European interests. The statistical data in the thesis, as well as previous research, show that even though the EU economically in many ways had become an equal partner of the US during the second half of the 20th century, the union still faced US influence and dependence.The results of the thesis can be explained with neorealist theories on power measured as an actor's distribution of capabilities and balancing of power. An actor that is equipped with the world's leading currency is more independent from others. Other actors, on the other hand, become increasingly dependent on the major currency and the policy of its owner.

Since 1983 all Swedish companies are legally obliged to allow themselves to be audited. Recently the question of whether small companies should be subject to this or not has frequently been discussed. Many find it superfluous and think it ought to be abolished. In England small companies no longer have to be audited. However, in a study by Jill Collis it has been shown that a large number of companies choose to be audited although there is no obligation for them to do so.

The purpose of this study is to discover and explain the influences of media coverage of organizational crises on crisis communication, and vice versa. The study also shows how mediated crises develop, and how media framing and news sources affect this development.Carried out as a case study of three Swedish mediated crises, the methods used are quantitative and qualitative content analysis of media content from four Swedish newspapers and four organizations' press releases from the studied crises.Mediated crises develop through their specific pattern regardless of, but not independent from, the organizations' crisis communication. The crisis communication is used as an elite source in media reporting from the crises, but it can not control the mediated crises. However, it influences framing, and the possibilities to influence media reporting are better in the pre-crisis phase and the culmination..

The number of locals in Stockholm who chooses the bike in front of public transport has increased significantly in recent years. The product purchaser of this project, Joakim Victorin at Sigma AB, has a keen interest in cycling, which resulted in a fairly obvious topic of this project; through a web application Sigma AB wanted to make it possible to handle results from professional as well as amateur competitions in cycling.The purpose of this web application is to simplify reporting and handling of competition for both small and bigger bicycle races. By providing the users of the system a platform independent client, any available device may be used.This thesis has followed the development principles which prevail on the ASP .NET MVC 3 concept. When developing the system the Microsoft Visual Studio 2010 development environment was used. The framework and the pattern of ASP .NET MVC 3 is a prominent part of today?s web development.

This thesis analyzes the media debates generated by the election of Omar Mustafa to the board of the social democratic party, and the appointment of the conservative Minister of Labour, Elisabeth Svantesson. More specifically, the aim is to analyze newspaper material through a discourse analyze, to see if and how religious affiliation effects the possibilities to act as a political representative. Theories of othering and intersectionality serve as theoretical points of departure. Further, chains of equivalence from Laclau and Mouffe?s discourse theory are used to study how categories as ?us? and ?the other? are constructed in the material, and how these processes of categorization relate to the intersection of religion, gender and ethnicity.

The aim of this graduate essay is to elucidate and compare the approach to learning that emerges in texts about the two educational practices Montessori and Reggio Emilia.The guiding research questions in this study are:What do Montessori and Reggio Emilia that learning is about?The mean Montessori and Reggio Emilia that learning goes to?How do you describe the Montessori and Reggio Emilia justification why it is important to learn? Through a poststructural theoretical framework and text analysis the study focused on what has been written about learning in the traditions of Montessori and Reggio Emilia.The results of the study indicate that both Montessori and Reggio Emilia look at the child in a similar way in which the child have the desire to explore and learn. Both pedagogy traditions think that the child will develop into independent people who can change society in the future for the better and with a democratic basis.The study also reveals how the Swedish curriculum (Skolverket, 98/10) is inspired both by the Reggio Emilia and Montessori traditions through describing how preschool should stimulate and challenge the child's development and learning, utilize and strengthen the interests of children to learn to conquer new experiences, knowledge and skills..

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.

This thesis has been written at Linköping University for the company Instrument Control Sweden AB (ICS).ICS is a small company located in Linköping that develops software and hardware for Unmanned Aerial Vehicles, UAV. At present, ICS has a fully functional autopilot called EasyPilot but they want to reduce the autopilot?s size to make it more attractive.The purpose of this thesis was to investigate if it was possible to reduce the size of the autopilot and how, in that case, it would be done. It was also necessary to examine whether the old processors should be replaced by new ones and how hard it would be to convert the old software to these new processors.To succeed with the goals many of the old components had to be changed for new, smaller ones. Some less necessary parts were also completely removed.

I denna rapport kan läsaren följa händelseförloppet med framtagningen av en fysisk mood-board med tillhörande grafisk manual. Läsaren kommer att få en allmän förståelse för hur det semantiska hos en produkt påverkar dess användare samt hur detta påverkar produktens resultat på marknaden. I projektet pressenteras en tämligen oanvänd metod som, kortfattat; syftar till att ta vara på en målgrupps specifika känslor om exempelvis en produkt för att göra denna mer optimerad. I detta projekt handlade det mer om att ta fram specifika strukturer vilka tillslut kom att leda till ett antal speciellt utvalda ytor och material åt företaget Tylö® AB. Materialet tillsammans med speciella ytor skall komma att skapa en mer elegant känsla i deras kommande sortiment.

The purpose of this study is to explore and understand the social and structural dynamics of an organization working with questions regarding development. The organization in question is Vi-agroforestry, a Swedish based NGO that works around the lake Victoria basin and the focus will be on their office in Rwanda. I have used a qualitative approach and conducted participatory observation as well as semi-structured interviews to gather data. I have emanated from the individuals in the organization by using a theory of microsociological organisationperspecive to understand how the employees create and is created by the existing social structures. (Blomberg, 2003) Even though the office in Rwanda only is a relatively small part of Vi-agroforestry?s operations it is still highly individual and independent from the rest of the organization.

This thesis seeks to investigate how Swedish first class hotels by use of IT can improve customer service and thereby increase the share of loyal guests. The authors have conducted a qualitative study predominantly consisting of an interview-based case study at one of Stockholm?s largest independent hotels. To get a broader and more generalized picture of the hotel industry four smaller studies at other hotels in Stockholm were also conducted. The findings suggest that the use of IT can improve the communication between the hotel and its guests and make possible a continuing relationship between visits that strengthens guest commitment.

The purpose of this study was to examine children's participation in court proceedings on supervised visitation and to analyse the descriptions of children in court verdicts. Eleven verdicts concerning supervised visitation resolved in 2014 were collected from two district courts in Stockholm County and studied with a qualitative textual analysis. The material was analysed with participation levels influenced by the ladder of participation for children developed by Roger Hart and with the theory of sociology of childhood. Our findings showed that children's opinions were mentioned in eight of the verdicts. In four verdicts the children's will influenced the courts decisions.

The purpose of this paper is to investigate some aspects of teaching environmental issues, as they are manifested in another culture. In this paper, I will discuss how you teach environmental issues, how the teaching environment is formed, and what an environmental issue means to a South African teacher, as well as, if there are any cultural aspects to what an environmental issue is. Seven observations were made and qualitative interviews with four teachers teaching Life Science in Cradock, South Africa - The results showed that these South African teachers, independent from each other, followed a similar pattern in their teachings. These patterns contain gathering information concerning environmental issues in the immediate surroundings, as well as using the text book and teaching environmental issues through lectures. It was not possible to draw a conclusion about the cultural aspects in association to environmental issues.

This paper describes how files and information can be shared in organisations and workplaces. We studied and compared the traditional file sharing in Microsoft Active Directory and the Social file sharing that comes with Microsoft SharePoint Sites. We used qualitative studies based on interviews with system administrators, management and by our own observations to acquire the necessary data. Using independent research, we were able to analyze the data and show the general difference between the traditional and the social file sharing systems. Social file sharing enables the user to easily store and share files in a flexible online environment.
