This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.

Fokus på hållbarhet i företag ökat kraftigt på senare år. Ett resultat av denna hållbarhetsutveckling är GRI (Global Reporting Initiative), en organisation som utvecklar ramverk och ger vägledning för innehållet i företagens hållbarhetsredovisningar. Svenska Regeringen på initiativ av Maud Olofsson var först i världen med att kräva att alla svenska statliga företag, från och med räkenskapsåret 2008, ska upprätta en externt granskad hållbarhetsredovisning i enighet med GRI:s riktlinjer G3.  Den här studien syftar till att undersöka hur de svenska statliga företagen har påverkats av regeringens nya krav. Studien innefattar en undersökning av sju statliga företag som idag redovisar hållbarhet i enighet med GRI:s riktlinjer. En kvalitativ fallstudie har använts för undersökningen. Efter intervjuer med företagen kan det fastslås att det nya regeringskravet till viss del är en kostsam process.

Abstract During object-oriented system development, programming should be preceded by analysis and design to assure that the system fulfils the demands of the customer and simplify during the development phase and documentation. When modeling the analysis and design phases, several different notations may be used. One of these is the UML (Unified Modeling Language) which this thesis will cover. The aim is to compare the use of the UML i practice versus what is said in the literature. The investigation is built upon interviews at different companies to receive their reflections about the UML.

The aim of this study is to describe and analyze how Bolaget, a paper published by the Swedish alcohol monopoly retailer Systembolaget, constructs issues of alcohol in 18 preventive articles published between 2009 and 2012. More specifically the essay focuses on the consequences of alcohol, as well as its consumers and functions. Systembolaget is a distributor of alcohol and at the same time has an assignment by the state to reduce alcohol-related harm. This double role makes the alcohol prevention of Systembolaget, and their perspective on consequences, consumers and functions of alcohol, an interesting object of study. The theoretical and methodological basis is Fairclough?s critical discourse analysis.

Housing cooperatives in Sweden practice very long depreciation times for their buildings and assets, subsequently depreciation costs are very low. This study aims at addressing issues relating to potential upward revisions of these costs and the revenue levels needed by housing cooperatives to address these changes, while also providing a detailed summary of some chosen financial ratios under different circumstances. This study's results are based upon recent (2015) market data within the Stockholm region, collected through a manual process and analyzed quantitatively. On average, housing cooperatives EBIT do not cover their financial costs and have low profit margins. The average depreciation time is considerably above what a technical evaluation by other sources may state.

The aim of this master's thesis is a comparative study on units for civic information in Göteborg. The study is based on a project currently in progress at the main public library in Göteborg. It is observed that according to the library's mission statement the library aims to become the most competent intermediary of civic information in Göteborg. This statement suggests a competitive strategy towards other intermediaries of civic information. The mission statement does, however, also state that their goal is to be obtained in cooperation with other intermediaries.

The aim of this project was to describe and to evaluate five small sewage treatment plants in the municipality of Laholm, Sweden, in order to investigate the treatment efficiency and to evaluate if effluents comply with discharge permits. The treatment systems were designed to treat effluents from 90 to 500 population equivalents. A report on the design and the present state of each sewage treatment plant has been made. This was made based upon previous documentation on water quality and by new sampling campaign as there were only a few previous measurements. Data has been evaluated and remedial actions proposed for those treatment plants that don?t fulfill discharge permits.

During the time of membership in The European Union Swedish domestic policy has gone through many changes. A lot more political areas are being influenced by the EU policy. Today every ministry has got some sort of EU office. Swedish politicians are functioning on two arenas, domestic and European. At the same time Swedish membership has gone from being highly discussed to being a state of normality.

The thesis aims to study how rainbows families are being treated by the authorities and the surroundings. It focuses on how homosexual parents are met in society. Although, homosexuals have the legal right to have a family and enter into marriage, the social norms are still far behind and rainbows families are seen as ?the others? and abnormal.  Earlier researches have been studding how the authorities still assumes that every family are living in a heterosexual family constellation. By this assumption they exclude families who are not living in a heterosexual family.

The purpose of this study is to describe how the employee appraisal is perceived by managers, employees and representatives from human resources departments. The empirical material con-sists of 15 interviews: respondents were two representatives of the human resources departments, four unit managers and nine employees who work at a state institution or municipal management. In the study, I adopt a sociocultural perspective, with the communicative relational perspective. The latter is a special education perspective in which the interpenetration of participation, com-munication and learning emphasized.The result shows that the majority of employees would like to see that the talks will be held more frequently than once a year. One of the managers has in cooperation with his co-workers devel-oped a model based on that each year, in addition to salary talks, have an individual conversation, a conversation with each group and individual follow-up talks.

Computer programs must give a technical effect that goes beyond"normal physical interaction"to be considered to belong to a technical field. The invention shall be be susceptible of industrial application, which means that it should be possible to reproduce or use in any other industrial way. The reqirement that the invention shall be new means that the technique must not be previously known because of patents, published articles, etc. That an invention shall be a contribution to the state of the art in a technical field means that the invention shall not be obvious to invent for a person skilled in the art. Patents do effect the innovation among the inventers, but in most industries most inventions would be invented independent if there was a patent system or not.

This master thesis is intended to give an increased understanding of the stress state in an axle, which is assembled in one of Atlas Copco?s mountain drilling rigs. The main problems investigated were how the axle is affected when the bearing is worn, when the pretension is varied, and how to dimension the axle. Answers to these questions were found by using hand calculations, practical testing and with Finite Element analyzes. The dimensioning of the axle is currently based on the bending stress, but the author?s opinion is that the axle should be dimensioned considering the equivalent stress.

Partnering is a collaboration method where the contractor and the client work together, based on a mutual trust towards each other and with a common goal for the project. The method originates from the United States where it was early adapted by the U.S. Army Corps of Engineers. It later spread internationally where the United Kingdom and Denmark were early in Europe to see the potential with partnering, to help aid with the issues they were having where construction projects kept running late, going over budget and lacked in quality. By using partnering you can achieve a shorter building time, improved work relationships and enhanced efficiency and cost effectiveness.

The disintegration of the Soviet Union was a vast experience, not solely for the former members and inhabitants of the Soviet Union, but also for the rest of the world. This thesis examines Estonia and Uzbekistan's different experience with transition. By examining three different aspects of transition I seek to explain Estonia and Uzbekistan's different outcome of transition. Estonia has since their independence been fully aware of the process that started with their independence. They have reformed both the political and economic system, the industry is privatized, institutions democratic and Estonia is today a member of the European Union.
