Avbördningskapacitet för Traryd kraftverk: en modellstudie vid dimensionerande flöde
Sydkraft Vattenkraft AB owns and operates the Traryd hydropower plant, located in the river Lagan in the southern part of Sweden. The gravity dam is classed according to RIDAS guidelines (Hydropower Industry Dam Safety Guidelines) as a class 1B dam. This means that the dam must discharge a class 1-flow which has a return period of 10 000 years. The inflow into the dam has been calculated in an earlier report to 495 m3/s, with a waterline at an elevation of 126, 3 meters above sea level. The gravity dam has a discharge system with two rectangular weirs, which results in a smaller discharge than the necessary 495 m3/s.
Diskursteori möter idrott och hälsa
Through a discourse theoretical apparatus, this study examines Sweden's national curriculum, which is constructed for primary schools, pre-school class and leisure time classes. The study also examines the syllabus in physical education and the supplied comment material to the syllabus, the above mentioned material all valid from 1 July 2011. Using cultural researcher Marianne Winther Jørgensen's and communication researcher Louise Phillips interpretation of the political theorists Ernest Laclau and Chantal Mouffe's discourse theory, the study identifies several discourses in the new curriculums. The analysis shows that the curriculums writers construct their expectations through a rhetoric that is perceived as instructional and descriptive. The analysis identified eight discourses, woven into three "orders of discourse", the body, health and physical education.
Barns tankar om älven : Förskolebarns förståelse av älven och vattnets miljö
AbstractThis research is about pre-school children?s conceptions of the river and the water environment. The aim of this study was to apply a new teaching method based on the outside learning, as well as to test the method and see if it works, i.e. if children get more knowledge this way compared to ordinary methods like teaching in the class-room which involves showing pictures and discussion of them.The main questions in this study were how children get new knowledge through outside learning and how effective this learning method is, i.e. how much they noticed and learned about the river and the water environment as a result of that outside observation.
Utredning av laserskärningens materialpåverkan inför drag- och slagprovning : Teknisk Fysik med Materialvetenskap
An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.
En ängel och en demon. En idéanalytisk studie om tendensromanen En natt vid Bullar-sjön av Emilie Flygare-Carlén.
The purpose of this master?s thesis is to describe by a gender approach what ideas and values are expressed in the novel One Night at Bullar Lake and how they do coincide to a tendency. We also want to discuss authority and class divisions and how these can be connected to the novel and the author. Our final question is to examine in what way the voice of the female author is represented in the novel. To approach our material we use Yvonne Hirdman?s theories about the construction of sexes and Susan Sniader Lanser?s work about voices of female authors, as well as Horace Engdahl?s studies about the silent voice in literature.
Pedagogernas arbetssätt i en mångkulturell kommunal skola och en friskola : Ett interkulturellt perspektiv på undervisning
The purpose of this study is to search for and compare how teachers in a multicultural municipal school and in a multicultural independent school design their teaching to benefit all the students in the classroom, regardless of background.I wanted to get information about how teachers work from an intercultural perspective. To get information I used qualitative methods, which includes interviews and observations. I interviewed four teachers working in a primary school. Two from a independent school and two from a municipal school.The result revealed that both the independent school and municipal school are working from an intercultural perspective where they try to find different methods to reach every student in the class. Their biggest similarity is that the teachers put a lot of effort on language development since the Swedish language is key to the Swedish society.
Musik- ett verktyg för språkutveckling : En jämförelse mellan skola och förskola
Abstract The purpose of this essay is to compare in what way pedagogues in pre-school in comparison to pedagogues in school use music as an implement to stimulate children?s language development. The essay is built on qualitative written interviews on four pedagogues, two pre-school teachers and two class teachers, along with relevant literature concerning music in relation to language development.In the interviews it was shown that music is used in a greater extent by the pre-school teachers, compared to the class teachers. Activities containing elements of music is situated on a daily basis in preschool, where the two interviewed pre-school teacher?s works.
"Förtroende till det läsande folket!" : Folkbiblioteket och folkbildningen under sekelskiftet 1900
The purpous of this master?s thesis is to explore how the swedish public library evolved between 1890-1911, before the state implemented the library reform in 1912. The material used to cunduct the study concists mainly of texts published during the time frame of the thesis in the form of books, booklets and articles from Folkbiblioteksbladet, a journal dedicated to the subject of the swedish public library.Drawing upon Habermas theory of the structural transformation of the public sphere and Bourdieus theories about taste as social distinction and symbolic capital, the thesis seeks to show how the public participated in the evolvement of the public library and which aspects of society that contributed to the public library?s establishment as an institution. The findings are also discussed in relation to previous research of the history of the Swedish public library.
Den Sociala Identitetens Inverkan På Subjektiva Bedömningar Av Att Dela Värderingar Med "Andra" - En psykologisk analys av motstridiga uppgifter i Integrationsbarometern 2004
This study examined some contradictive results in a report from the Swedish board of Integration. The contradiction was concerning the Swedish populations dismissive judgments of experience a shared ground of values between the Swedish society and those witch are generally held within Islam. These dismissive judgments were given at the same time as the population reported to have a lacking knowledge of Islam in general. To test for psychological aspects of these contradictions, the analysis was based on the theoretical ground of Social Identity Theory and Theory of Attributions. The study used an existing survey that examines people´s estimations of their own and other members of society´s fulfilling of democratic values.
Lagring av kyla med horisontella markvärmeväxlare för kylning av koncepthus i Mellanöstern
Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.
Rocchio, Ide, Okapi och BIM : En komparativ studie av fyra metoder för relevance feedback
This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.
Musik som kommunikation : en empirisk undersökning hur musik kan påverka startblocket av en lektion
Music affects us humans. Marketing has long made use of music as a means to enable customers to identify with a brand, and thus increase sales. The Influence of music is obvious, but can you use this on students, and how effective is it to use in a classroom?I will answer the question: how does soft music provide reassurance/create a harmoniums learning environment at the beginning of a lesson?By observing how students react and behave to the playing of soft music. My aim is to create different strategies that teachers can effectively use to get students to ?jump in? to their lessons without wasting 5-15 minutes of class time.Professor Lennart Grosin conducts research into what is in Sweden called PESKO.
Energieffektivisering av teknikhus
Syftet med detta examensarbete var i huvudsak att undersöka möjliga energieffektiviseringsåtgärder för de av Trafikverkets teknikhus som har till uppgift att säkerställa järnvägsdriften i Sverige. Störst fokus låg på framtida nybyggnationer av teknikhus men även nuvarande teknikhus undersöktes i viss mån. I arbetet analyserades även mätdata från fyra olika teknikhus runt om i landet i syfte att undersöka omgivningens påverkan på inomhusklimatet, hur bra den önskade inomhustemperaturen uppehålls i teknikhusen samt hur väl installerade värme- och kylsystem fungerar. Trafikverket är en svensk myndighet som bland annat har ansvar för byggande, drift och underhåll av statliga vägar och järnvägar. Trafikverket jobbar aktivt med att minska energianvändningen och miljöpåverkan i sin verksamhet.
Weimarrepubliken 1918-1933 En metodologisk individualistisk studie om demokratins kollaps
The purpose of this essay was to analyze the collapse of democracy in the Weimar Republic. This was done by analyzing some of the most turbulent crises in its history like the communists attempt to take power in 1919, the kapp-putsch of 1920, hyperinflation 1923 and the economic depression 1929-1933. The method that I used in this essay is called methodological individualism. It was an analytical framework which helped to understand the citizens view on democracy and legitimacy. The theoretical framework was based on Juan J.Linz and Seymour Martin Lipsets ideas on legitimacy and efficacy.
Förhandlingslösning som alternativ till fortsatt militär kamp : en studie av två irreguljära parters val
The Swedish Armed Forces tend to ask themselves if it is sufficiently multinational interoperablefor participation in international operations. An equally valid question today should be whether theSwedish Armed Forces are sufficiently nationally / internally interoperable, between their branchesof service, to be able to conduct independent operations based on the joint warfare theory.The lack of ability to joint warfare in the armed forces in general and the Swedish Armed Forcesspecially constitutes the essay´s fundamental problem. By using Codners and Sjöbloms custominteroperability theory, the Swedish Armed Forces documents were analyzed to highlight anyweaknesses related to joint warfare and national interoperability between Ground and Air Forces.The survey shows weaknesses linked to the custom theory and Swedish Armed Forces governingdocuments. The ability of a national interoperability is limited between Ground and Air Forcestoday, mostly because of weaknesses in the Swedish Armed Forces strategic concept which doesnot describe the importance of joint warfare at all levels sufficiently. This leads to deficienciesreflected in doctrines, regulations, technology, techniques and exercises.
