This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

The aim of this paper is to investigate the subject matter of visual communication in presentation brochures of two Swedish regions: Region Halland and Region Dalarna. My focuses are the following questions: what is the aim of the brochures and in what ways does the visual material relate to that aim? How can strategic communication be defined through a visual perspective and in what ways is it useful in the context of presentation brochures of the regions? What sort of communicational functions are specific for the visual material in relation to the written language of the brochures? Lead by these questions, I start by analyzing the brochures through a textual analysis and a social semiotic approach. The result shows that the aim seems to be both political and commercial, but that the visual elements relate more strongly to the commercial aim than to the political aim by the way they strive to present a positive image of the region. The visual elements work in strategic ways that I define as visual strategies.

This study examines how the local rescue services relate to the brand of the rescue service and the concept of brand management. To understand the attitudes against the brand and brand management, empirical data, theoretical modelling of brand and current laws have been discussed together in a try to get an overview how the rescue services practically works with the brand. The study results are based on a questionnaire survey and qualitative semi-structured interviews. The survey was sent to employees working with the communication of the rescue service. The interviews were held with two employees working with the communication of the rescue service and two fire chiefs.

The study examines how social media can be used in a business-to-business context. To understand the communication conditions, factors has been identified that affects the choice of communication channels for different types of information transferred between parts. Furthermore, the study investigates the underlying reasons for why certain communication channels are chosen before others, in different situations. The study results are based on qualitative semi-structured interviews with employees in a small engineering consulting company. The investigation has focused on employee communication and choice of communication tools primarily in relation to the business relationship.

The purpose of this study was to examine how modern information and communication technology influence collective action within the framework of social movements. By studying the protests in the Arab World 2011, and focusing on the social movements in Suleimanya in northern Iraq, by observation taken on place, the essay discusses that collective action is closely related to the use of technology, for example cell phones and Internet.Result shows that modern communication technology has enabled immeasurable access andconnection between individuals throughout the world, which seems to be different from previouscollective action. The new communication channels in the form of social media, has been used for the dissemination of information and news, documentation, organization and membership recruitment in the social movements in the Arab World and Suleimanya. The new social movements have the tendency to be decentralized and flattened organized, they are now self-organizing and that they only do a whole as global patterns, as evidenced by the social movements in the Arab World andSuleimanya..

AbstractBakgrund: När människor tar del av nyheter via sociala medier som Twitter och Facebook ärdet möjligt för andra användare i de sociala medierna att påverka uppfattningen av innehållet.Det kan exempelvis ske genom att lyfta fram, tona ned, omtolka eller omgestalta nyheterna.Hur detta sker och vad det får för konsekvenser för hur människor uppfattar nyheterna hartidigare inte undersökts. Dessutom saknas det kunskaper om vilka nyheter från massmediernasom sprids i social medier, i synnerhet i Sverige.Syfte: Beskriva och jämföra vilka nyheter som sprids i sociala medier (Facebook och Twitter)samt undersöka de psykologiska orsakerna till varför de sprids vidare.Metod: Artiklar (N = 89 450) från de tolv största svenska nyhetssajterna under två månader ibörjan av 2014 undersöktes hur de spreds på Facebook och Twitter med en kvantitativinnehållsanalys. Två oberoende experiment (N = 311) undersökte effekten av kritik på nyheter, inbäddade i Twittermeddelanden, samt effekten av antalet retweets (vidarebefordringar) på fortsatt vidarespridning.Resultat: Majoriteten av de mest delade artiklarna på Twitter handlade om ett fåtal ämnen (rasism, extremism, feminism och välfärd). 17 procent av artiklarna hade delats minst tio gånger på Facebook eller Twitter. Artiklar delades i regel tio gånger mer på Facebook än på Twitter.

Skyfall kan leda till stora konsekvenser för samhället, framförallt i en stad då den urbana miljön är känslig för extrema händelser. Västerås stad har tidigare drabbats av skyfall där följderna har varit kostsamma. Den senaste forskningen pekar på att intensiva regnhändelser kommer bli allt mer vanligt förekommande, därför är det intressant att undersöka vilka konsekvenser dessa regn kan leda till.En analys har gjorts med utgångspunkt från SMHI:s lågpunktskartering över Västerås. Utifrån denna kartering undersöktes vilka förorenade områden, bostadsområden, exploateringsområden, infrastruktur, vårdcentraler, skolor, nätstationer och prioriterade pumpar som ligger i lågpunktsområden. Denna jämförelse har gjorts i ArcGIS.

This work is a part of the project ?Våtmarker i odlingslandskapet ? uppföljning av miljömålen? (Wetlands in arable land ? following-up of the environmental goals). The main objective with this project is to study nitrogen and phosphorus retention in a constructed wetland by using mass balance calculations. Continuous measurements of nutrients and water flow through the inlet and the outlet of the wetland are made. However, substantial amounts of nitrogen and phosphorus were assumed to reach the wetland with a drain-pipe transporting wastewater from nearby houses (10 persons).

Purpose/Aim: The purpose is to describe, analyze and compare the two communication campaigns Världens Chans and Utrota Fattigdomen Nu, and discuss how and to what extent communication campaigns in Sweden can be used to reduce global poverty. The theoretical framework is mainly based on communications strategies and other relevant aspects of the planning process of campaigns.Material/Method: Within the qualitative case study as an overall method, the main material to the two cases is obtained through five qualitative interviews with the premier representatives of the campaigns.Main results: Världens Chans can be seen as an information campaign by the government which purpose is to contribute to the fulfilment of the millennium goals by drawing the attention of the public to their existence. Utrota Fattigdomen Nu, on the other hand, is an influence campaign by the civil society which purpose is to exterminate poverty by putting a pressure on power holders and to change the attitudes and the behaviours among the public. Both campaigns are based on a network with lots of different actors, functioning as opinion makers. Furthermore, communication campaigns are important tools in the fight against poverty..

Through a sociocultural perspectivethe purpose of this study is to investigate how preschool teachers look at quality development in preschool and how they perceive their participation in this development.I have used a qualitative method based on five interviews with preschool teachers from three different parts of Sweden. I used an interview guide with open questions. The interview answers were categorized in themes based on the responses which were most frequent. In the result I have been using an analysis based on these themes. The result showed that the preschool teachers consider that the leadership style affects their work.

Today's technology offers a variety of opportunities to interact with the interactive systems. Human-Computer Interaction in the last decade is the area of research that has contributed the most to this development. But how is this interaction perceived? The user experience is something that is formed by the interaction between human and the computer interactive systems. The objective of this thesis is to investigate how the user experience differs depending on how one interacts with a game.

The aim with this essay is to emphasize the problems that ethnical belonging causes at schools today. We have chosen to examine and compare two schools with each other, one school is called ?the new school? situated in Stockholms kommun and the other school is called ?the old school? belonging to Huddinge kommun. We have had contact with these two schools for a longer period as substitutes and students. This essay is based on how these two schools prominently differ from each other.

Stormwater run-off from surfaces such as roads or rooftops is often polluted with heavy metals and nutrients. Many of these substances can cause great damage in biota if they end up in the recipient. In Sweden constructed wetlands and ponds for treatment of stormwater are frequently used, since research has shown that these treatment ponds are reducing stormwater pollution considerably to a low cost. The knowledge of these pollutant removal mechanisms and how follow-up and assessment of the ponds should be performed is still limited.To determine the pollutant removal efficiency of the stormwater ponds it is recommended that flow-weighted water samples are collected from both the inflow and the outflow of the pond. This method demands considerable resources of time and money for installations and analysis.

Our study aimed at gaining insight of co-workers experiences of different factors that affects the verbal communication and leads to dialogue and misunderstanding between co-workers and their managers. The empirical material was gained from semi-structured interviews with co-workers at various departments within the same organization. We used a hermeneutic interpretive approach and our data was analyzed concerning different factors affecting communication. The result has been interpreted using the theories of deliberative conversations and dialogue competence. We have also used Illeris theory of learning.
