Detta examensarbete behandlar dynamiska vindkraftmodeller i simuleringsprogrammet Power System Simulator for Engineering (PSS/E) som används av Svenska Kraftnät vid analyser av det svenska stamnätet. Syftet med examensarbetet har varit att förenkla Svenska Kraftnäts hantering av vindkraftmodeller vid olika analyser av nya vindkraftparker som ska kopplas in på stamnätet. Detta gjordes genom att undersöka om dagens modellering av vindkraft, bestående av negativa laster och tillverkarspecifika vindkraftmodeller, kan ersättas av en generisk representation med de modeller som finns inbyggda i PSS/E. Rapporten ger en teoretisk beskrivning av vilka tekniker som används i vindkraften idag och hur de vindkraftmodeller som används i PSS/E är utformade. För de inbyggda modellerna i PSS/E har både vindkraftverk med dubbelmatad asynkrongenerator (DFIG) och vindkraftverk med fulleffektomriktare studerats. Resultaten visar att en generisk representation av vindkraftverk med DFIG kan göras med den inbyggda modellen i PSS/E med de parametervärden som finns rekommenderade i denna rapport. I den inbyggda modellen för fulleffektomriktare finns dock begränsningar som gör det olämpligt att använda en generisk representation för denna vindkraftstyp. Övriga slutsatser som dragits är att de inbyggda vindkraftmodellerna i PSS/E inte är tillräckligt flexibla för att fullständigt kunna representera ett dynamiskt beteende från en godtycklig tillverkare i händelse av ett systemfel..

This essay studies what has been written about religious experience and visions both in the past and now. It deals with both the religious experience and tries to explain how and if there is any place in the modern society for religious visions and experience. The essay has a strong theoretical perspective to psychology of religion as presented by Anton Geels whose writings in the subject have been of one of my main sources.The study shows that people of all times and cultures have had religious visions and the feeling of a divine experience even if this has changed because of tradition, time and place. Religious experience and visions can furthermore occur both in a spontaneous, unprepared way as well as being cultured through ascetic practice in order to facilitate the divine reception. The study also shows that religious experience in no means is reserved for special ?chosen ones? but can occur to each and every one, no matter what class, race or position in life.

Titel: Sportevenemang ? Kollektivt fenomen eller problem? Författare: Ida Jensen och Ebba Nordlund Syfte: Vår uppsats har som syfte är att skapa en inblick av vad som händer då en liten ort blir en uppmärksammad sportevenemangsdestination. Frågeställningar: Hur har platsen betydelse för sportevenemang och tvärtom?Varför uppstår många olika konflikter kring sportevenemangen på små orter? Studieområde: Vår empiriska studie tar sin utgångspunkt i de konflikter som uppstått som en följd av de sandsportsevenemang som varje sommar arrangeras i Åhus. För att uppfylla uppsatsens syfte och besvara frågeställningarna har vi valt att utgå från tre teoretiska teman; Sportevenemang som strategisk resurs, Platsen som utgångspunkt för evenemangen och Konflikter på platsen på grund av sportevenemang.

This essays overarching aim is to contribute to the theoretical discussion of transformation processes that are shaping the urban landscapes and further to problematize contemporary planning discourses in Sweden. Drawing on the concept of Foucault?s heterotopia and actor-network theory for spatial analysis, the paper seeks to analyze the complex urban landscape transformation process as an emergent property of human and non-human actor-networks seeking to transform and order space. With the district of Rosenlund in Gothenburg as a starting point, this thesis intends to examine how the cultural infrastructure - used by the residents and visitors of the city - are related to the city's planning and development processes. The case study is based on a boat (Rio Rio) in Rosenlund canal that is defined as a cultural infrastructure.

The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.

The purpose of this work has been to understand the reading group from the perspective of the society. The studyhas taken place in the city of Västerås and the results can thus not be used in a more generalized sence. Byfocusstudies conducted with members from four different reading groups connected in different ways to the libraryin Västerås I have reached the following conclusions.According to Jürgen Habermas theories the reading groups, with their ideals regarding education and meetingswhere everybody are equals, belong in the part of the public sphere that he calls literary. There are someconnections to the political sphere, for exempel the down to earth quality of the literature that is the choice ofthe groups and their way of discussing it.One problem that occures when one tries to apply Habermas idéas regarding the public sphere on readinggroups is that the criteria Habermas considers as vital to sphere for it to work properly does not seem to workon the reading groups. Inclusion, eqality and freedom of subjects are necessary to create a public sphere.

To achieve the goals that the government has put in place for equal opportunities in the labour market, the Swedish law is divided into two separate regulatory frameworks. One is positive action to promote equal opportunities and the other is the prohibition of sexual discrimination. Since males, despite the measures taken so far, still have a great advantage on the labour market, the law concerning equal opportunities has an exception from the prohibition of sexual discrimination, whose purpose is to promote the progress of equal opportunities, also known as preferential treatment. The regulations concerning preferential treatment allow the employer to hire a less qualified person from an underrepresented gender in spite of the presence of higher qualified applicants of the overrepresented gender. The purpose of this paper is to investigate the meaning and the application of preferential treatment as well as to give an insight to the argumentation around its application.

Since their invention in 1999, CubeSats have become a widespread standard for small picosatellite missions. CubeSats allow for quick development of satellite payloads and launch in space without the high costs of a normal satellite. Emphasis during the CubeSat design process is placed on use of commercialoff- the-shelf (COTS) components and reuse of previously-designed units.This report describes the interfacing of a scientific magnetometer, the Small Magnetometer in Low-Mass Experiment (SMILE) to such a CubeSat mission, the Space Weather using Ion spectrometers and Magnetometers (SWIM). Design of a complete platform for use in multiple such missions is presented here.Modularity is one of the key aspects followed in the course of the work. A new board containing the analog pick-up and compensation circuitry for SMILE has been designed to fit inside a CubeSat frame.

The aim of this thesis is to investigate the points of view of three groups of actors about their local learning center and its collaboration with the library. By interviewing groups of actors from the municipal sector, the library staff and students, I aim to investigate their associations of the learning centre, what kind of services it should offer, and how they understand the role of the library staff in specific collaboration between the public library and the adult education administration. The study design is based on Gunnar Grepperud?s and Terje Thomsen?s three missions for a local learning centre; the mission of a broker, a meeting place and a motivator. I also use Carol Kuhlthau?s levels of mediation as an approach to investigate how the actors want the library staff to work in relation to the centre.

This master thesis is about a place that has a story to tell. Olsson?s garden came about when Mr Carl Oscar Olsson acquired a piece of land in Landalabergen in the beginning of the 1930's and at that time he started his industrious work of uniting much of Sweden's flora in his garden. Since the very beginning Olsson's garden has played a lot of different rolls in a variety of situations and meant different things for different people. Today one can find traces from Mr Olsson's life and deeds in the garden.

This study deals with a research on what the opening sounds in movies tell us about the story that we are about to follow. The purpose is to examine if and how the sound in the first five minutes of the movie contribute in giving information about the film?s genre. The theoretical base includes both genre theory and Michel Chion?s theory on film sound.

Syftet med vårt examensarbete var att undersöka teorier om platsmarknadsföring i en svensk kommun och även undersöka vilken roll invånarna hade i utvecklandet av kärnvärden, som är grundläggande för platsmarknadsföringen. Vi gjorde en kvalitativ studie där vi intervjuade två respondenter och åtta invånare i den skånska kommunen Östra Göinge för att lokalisera information kring vilka kärnvärden kommunen skulle kunna grunda sin platsmarknadsförnig på. Intervjuerna jämfördes sedan med varandra och även med tidigare teoretiska studier inom platsmarknadsföring för att lokalisera tre kärnvärden som vi kunde använda som bas i en riktig marknadsföringskampanj, närmare bestämt en mässmonter. Studiens resultat visade att invånarna och respondenterna hade mycket lika åsikter kring hur Östra Göinge uppfattades och att en platsmarknadsföringskampanj måste grundas i invånarnas åsikter för att kunna lyckas optimalt..

Studien beskriver globala IT-företags arbete med kompetensfrågor ur ett centralt och lokalt ledningsperspektiv utifrån behov av att implementera organisationsgemensamma arbetsprocesser och IT-system för kompetenshantering. Med utgångspunkt i detta beskrivs också de utmaningar som uppstår vid implementeringen samt rekommendationer ges för hur dessa kan hanteras. Beskrivningarna baseras på en generell kartläggning av globala företags arbete med kompetensfrågor, tidigare forskning om IT- företags implementering av kompetenshanteringssystem samt en fördjupad studie av ett IT-konsultföretags implementering av ett organisationsgemensamt IT-system för kompetensutveckling och karriärplanering. Lokala ledare vid de globala IT-företagen har till stor del använt sig av enkla och flexibla arbetsprocesser och IT-system för hanteringen av kompetensfrågor. Kunskap om personalens kompetens har främst delats genom nätverkande mellan de lokala ledarna.

School ground development is becoming increasingly popular in Sweden today and local community settings are also seen as an important resource for education. The debate today raises the question about the whole city?s pedagogic potential. Outdoor education is a pedagogy that comprises outdoor learning with focus on the sensual experiences. Connection to the classroom education is an important part of the pedagogy and so is the place for the tuition.But how should the place for the tuition, i.e.

In the increasing urban environments and the modern societies demands for sustainability there is a challange in planning cities with a balance between density and a satisfying access of recreational environments. For attractive cities these environments need to be designed to fit every inhabitants? demands and opinions in some way. Increased knowledge and understanding is therefore needed about how different design styles in landscape architecture affect people and the cities. In this bachelor thesis benefits and disadvantages as well as the experience and impact of two fundamental design styles i discussed; naturalistic and formal/abstract design.
