Projektering av vindkraft i turbulensintensiva områden : med fallstudie för Wallenstams planerade park vid Skuggetorp

Along with the rapid expansion of wind power in Sweden during the last decades the competition about favorable areas has hardened. This among other reasons has caused the projectors to look into development of wind power in forests. There are several aspects regarding fatigue loads on the constructions that are severe in complex terrain, among which turbulence is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools to use: The ambient turbulence decreases with height and can therefore be regulated by the hub height of the turbines.

Design and Analysis of an All-optical Free-space Communication Link

Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

The results showed that there was a relationship between positive perfectionismand own influence, negative perfectionism and own influence, negative perfectionism andsocial influence.

Utvärdering av svensk vindkraft : Skillnaden mellan skogs- och traditionella placeringar

During the last years commercial Wind Power Turbines (WPT) has become larger regardingto the generator sizes and hub heights. Available hub heights around 100 meters is nowcommon, which has led to profitability for WPT located in forests where there normally are tolow wind speeds. The current knowledgement regarding turbulence and the variation in thewind profile for the outcome of the power production for the WPT in forests is limited.In this Master of Science thesis an investigation concerning forest located wind power plantshas been made. The purpose has been to investigate if plants located in forest perform lesscompared to wind power turbines located at more common locations.The analyses are based on statically material for determining the availability,production/generator size, production/hub height, production/swept area and how thetopography affect the production results.The analyses show that the variation in production result for WPT located in forest comparedto turbines located at other locations is small. The availability is high and the productionresults are good..

De nya riksdagspartierna och den politiska dagordningen

Engblom, Gustav (2009) De nya riksdagspartierna och den politiska dagordningen ?The new parilament parties and the political agenda.?1988 and 1991 the swedish parties Miljöpartiet, Ny demokrati and Kristdemokratiska samlingspartiet made it over the 4 percent threshold and successfully entered the Swedish parliament. Sweden was once described as one of the most stable political systems in the world, but the parliament elections of 1988 and 1991 showed that Sweden was no exception from the growing instability in west democratic political systems.The stability and instability that followed in the west democratic political systems is believed to be explained by the political parties? efforts to adjust to changes in their political environment. This has lead them to cartelize and the cartel party is believed to prefer stability over triumph for various reasons.The established political parties are believed to be able to manipulate the political agenda in such a way that political topics that would have caused great turbulence in the political system, if debated, are kept away from the political agenda.

Studentinflytandets roll på Kau : En diskursanalytisk studie kring studentens roll i universitetets organisation och verksamhet

The importance of student influence at the universities is something that is described in Swedish regulations as well as in local policies and documents for Karlstad University. At the same time there is no description for the interpretation of what student influence actually means. It is up to the university to decide what student influence should be at the university and how it should be represented in the organization and processes.The purpose with this essay is with a discursive perspective of analysis define how representatives of Karlstad University reflects how the student influence should be represented in the organization and if it is possible to connect it to the position as an actor of co-decision or of influenceThe analysis show that different levels of the university will describe the position of student influence differently, and that it plays different roles to keep up the quality of education at the university. It shows that it will be of more importance that student influence takes the role to influence the organization more than co-decide the nearer the student the process will come..

Vad är elevinflytande? : En kvalitativ studie på två skolor med fyra lärare, en utvecklingsledare och en rektor om deras syn på elevinflytande

Inflytande och gränssättning i förskolan : En undersökning kring hur fem pedagoger förhåller sig till inflytande och gränssättning i förskolan

This qualitative study is aimed to find out how teachers at one preschool relate to influence and boundaries. This has been carried out through qualitative interviews whose contents have been analyzed and processed. The theoretical framework of the study is the philosophy of John Dewey derived from Pragmatism, where thought and action is seen as one where the child needs to try and experiment to learn. We are two authors who stand for this study in which we both were present at all times for the interviews.The interviews revealed that teachers believe that influence is important for children's self-esteem, to become a good citizen of the community and to learn that certain things are expected. It also emerged that influence combined with boundaries is seen as very important.It appeared that the teachers look at influence in preschool in three different ways - influence here and now, influence in the future and influence for the children self-esteem.

The method I´ve used are interviews with three teachers and one pupil each aboutMusicality - how do the teachers and pupils look at the concept musicality generally and personally?Influence I- do the teachers believe that their thinking about musicality influence the pupils self-confidence and development?Influence II- do the teachers think that other pedagogues have influenced them in their teaching and thinking?My main results show that both the teachers and the pupils have similar apprehensions as their teachers, which points towards that influence can exist. The basis is however too limited to make any extensive generalizations.The conclusion of the paper is that we have to be aware of how we influence our pupils. They carry this ?knowledge?, whether it is positive or negative, all their life..

Ålandsfrågan : En studie ur ett medieperspektiv

AbstractThe purpose of this essay is to study in what way teachers in preschool work with pupils enabling them to gain influence and involvement in their learning.Influence means being able to make your voice heard which is an important component of a democratic society. Involvement is about being part of a community in which everyone is welcomed regardless of beliefs and opinions. Several of today's researchers believe that learning occurs in interaction between people. Teachers providing meaningful assignments to pupils, they become more motivated to learn.The study is based on observations of how teachers work with influence and involvement in controlled sessions, and interpretations of them. My results show that children become involved in their learning when they are confronted with a variety of pedagogical approaches to learning.
