The purpose of this thesis work is to create a prototype for an augmented reality application that isaimed to support service technician when performing service and maintenance of machines andengines. The prototype will be used for investigating what technical limitations there is and toestablish basic usability for the user interface. The method that is used is user studies and analysis toevaluate use cases and user stories. An iterative work process is then applied for design and theprototype is continuously user tested.The resulting prototype uses a Samsung Galaxy Tab 2 running on Android operating system. Theframework used for augmented reality is NyARToolkit which handles marker recognition andconnections to Android.
Flödeslogistik vid Laponia Hotel
The aim of this report is to analyse the logistics of a medium sized restaurant and give an overall solution for improvements on the restaurant's logistics. The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout.
Konceptstudie av drivmodul till bandskotare med hybriddrift
BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.
Centralitet och periferi i det nya Europa : Städer som regionala nav i samarbete och konkurrens
European cities of today are under the challenge to find ways to stay competitive and flourish in a rapidly changing world, where the old patterns of centrality and periphery not necessarily holds true. New and improved communication networks, a changed political geography in Europe, and the globalisation of not only the financial and industrial markets but also to a certain extent the globalisation of people, have all led to great challenges for cities and regions.In a changed spatial reality the classic monocentric models are challenged by newer models of urbanisation. The polycentric urban region is one such model which has been used to describe urban regions like the Randstad in the Netherlands and the Rhein-Ruhr region in Germany. Regions which lack the single dominant central city of the monocentric models of old, and instead shows a high degree of more equal-sized and sometimes more specialised cities in regional cooperation. The polycentric urban region is in that aspect a possible model for how other urbanised regions in Europe may act to be able to position themselves as attractive urban regions and regional hubs in the European urban network.Polycentric urban regions are not a universal solution, though.
Mot mer makt? - En studie om utvecklingsländers maktsituation i Världshandelsorganisationen WTO
This thesis examines the power of developing countries within the World Trade Organization (WTO). The research question is if there is a change in the power relations between developing countries and developed countries from the establishment of the WTO in 1995 and until mid 2006, and if so, why this change is taking place? The thesis has its theoretical starting-point within regime theory and views it from a critical theoretical perspective. A multidimensional why of dealing with the concept of power is being used to answer if there is a change in the power relations? The conclusion is that there is a small change in the power relations and that the developing countries are gaining more, but limited power.
?Man vill ju så mycket men man hinner inte? : folkbibliotekariers och personer engagerade i idrottsföreningars uppfattningar om möjligheten till samarbete dem emellan gällande barn och ungdom
The purpose of this bachelor?s thesis is to examine how public librarians and people engaged in sports associations think of the possibility of collaboration between their organizations regarding children and youth and furthermore how they think this collaboration and collaboration in general would or should be practiced. This is done in the light of the increasing necessity of collaboration in today?s information society as well as the view that reading and sports could make a good match. Focus is placed on the libraries? perspective and also on the respondents? perceptions and thoughts.

During the process the agile method scrum has been used as a working method.
Skolbiblioteket : om skolbibliotek i och utanför Sverige med fokus på Svenska skolan i Berlin
The focus of this thesis is the library at the Swedish school in Berlin, Germany. Being a school in a foreign country, and playing a role also as a public library, the conditions for the library are somewhat unusual. Considering those conditions, how should the library be organised and developed to meet the users' needs in the best way possible? To put the library in Berlin into a greater perspective, the first chapters of the thesis are dedicated to the issue of school libraries in Sweden; their historical development, their importance in the school curriculum and their present situation. Swedish research in the field of school libraries is presented and includes descriptions of theoretical analysing models.
Frekvensreglering i det nordiska kraftsystemet
Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.
Sexköparen - en kvalitativ studie om varför nän köper sexuella tjänster
The purpose of this study is to explore professionals? view on why men purchase sexual services with a focus on heterosexual prostitution where the man is the buyer and the woman is the seller. To achieve the studys? purposes and to be able to examine professionals? views a qualitative approach is taken with semi-structured interviews. Six professionals who work or have been working in the organisation KAST (Buyers of sexual services, own translation), who are situated in Malmö, Gothenburg and Stockholm, have been interviewed.
An explorative journey in understanding Social Entrepreneurship
The aim of this thesis is to examine the theoretical developments on social entrepreneurship. Our purpose is to create a better understanding of the phenomenon leading to new insights. We have categorized the knowledge of the concept into social economy, social ownership, social innovation and social missions. Drawing from our theoretical review we have chosen four empirical illustrations, Grameen Bank, Wikipedia, Basta Arbetskooperativ, Jörn Hälsogemenskap, and we have shown how these fit into the general description of the social entrepreneur. With help of our illustrations we show that it is complicated to pin point the core of social entrepreneurship as they each have separate structures, innovations, social missions and operate close to different sectors.
Citeringsanalys och citeringsteorier: En kritisk granskning
The purpose of this Masters thesis is to make an outline of different methods and theories within the field of bibliometrics and critically review their strengths and weaknesses. The author studied literature that discussed bibliometric methods and theories. The number of empirical studies that are based on bibliometric methods and theories are numerous and where principally excluded, but some empirical studies were included as part of the argumentation for and against different methods and theories. The author first gives an outline of which methods and theories there are and describes their different strengths and weaknesses. Citation analysis has many different fields of application such as information retrieval, mapping science, evaluative studies and monitoring literature.
Utveckling av mobiltelefonapplikation för kommunikation i ad-hoc nätverk med Bluetoothteknik
The purpose of this thesis is to develop an application for mobile phones that simplifies communication. The company Doberman wanted to look at possibilities to develop such an application that uses Bluetooth? technol-ogy to communicate in ad-hoc networks. The aim has been an application to run on mobile phones in which you can send messages and files to other devices and also add a user profile with personal information to share with others. The communication will take place in temporary networks created when Bluetooth enabled devices is in range of each other.The market for mobile phones has grown rapidly over the past years and is still growing.
Släktforskare ett nödvändigt ont? En undersökning av bibliotekariers och släktforskares attityder gentemot släktforskning på bibliotek.
The aim of this thesis is to examine how librarians and family historians experience their interaction at the reference encounter, what influences these views and how they affect the service; whether the family historians are aware of these views; which subject knowledge is needed and how this knowledge affects work performance; if there is a need for continuing education, and finally, if the family historians themselves can work as a resource for the library or the librarians? The thesis consists of three parts; in the first a theoretical frame was constructed around the concepts service, continuing education, subject knowledge and attitudes. Role theory was used as a theoretical background to show how expectations influence professional roles. The second part consists of the results given from the qualitative interviews with librarians and surveys with family historians that were performed. In the last part a discussion from the theoretical and empirical information earlier received was made.
Kan jag be och få potatisen? : Två förskolor och två olika sätt att organisera måltiden. En studie av måltidssamtalen och pedagogernas tankar kring måltidens språkutvecklande möjligheter
The purpose of this study is to investigate the lunchtime from a language development perspective. It will compare two preschools with different ways of organizing mealtimes and observe the conversations between teachers and children. It will also study the ways in which a meal is served and how it affects the conversations. In one of the preschools the children eat in a proper dining room where the food is served as a buffet while in the other preschool the children eat in the preschoolarea and the food is served in bowls on the tables. I also want to investigate how two of these preschool teachers reflect on the mealtimes as part of the language development plan.
