Konstruktion av turbinmodell för kaplanturbiner

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Utvecklingsarbete, Sagor : Läs- och skrivutveckling under ett sagotema

This thesis has the purpose that through a text analysis examine how four schoolbooks for high school treats the religions Judaism and Hinduism. The schoolbooks are from the years 2000, 2001, 2003 and 2009. The perspectives are from a religious viewing point, that means that the women are religious, Jewish feminists and Hindu feminists. The theories used are written by these women and are academic litterature.  The questions are how are women represented in the schoolbooks, is the feminist critique present or are the two religions represented and described in an invariable way, and is the description of Judaism and Hinduism consistent with the curriculum?The text analysis used in this examination means that reality is organized through and by the language used by the actors in that reality.

Biogasanvändning vid Käppalaförbundets Reningsverk: ? en värdering av miljöeffekter

This thesis calculates and compares the values of improved environmental quality due to future possible investment alternatives in biogas production facilities at Käppalaförbundets Reningsverk (Käppala Sewage Treatment Works) in an attempt to determine which alternative yields the highest such value. Käppala faces three investment alternatives for the usage of biogas. The alternatives are production of vehicle fuel, district heating and thirdly, heat and power production. Estimates of the value of environmental change are calculated for each of the three investment alternatives, and these estimates are then compared. The environmental change in question is the change in discharge levels of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter.

Debatten som inte förekom

The purpose of this paper was that through discourse analysis look at how gender and the equality debate is created between two head debaters and commenter's on a forum. We have used Norbert Elias and John L. Scotson´s (1999) theory about Established and Outsiders to see power struggles between groups in the debate. With Jonathan Potters analysis tools in his book Representing Reality (1996) we were able to analyze the debate texts. Using discourse psychology, we were able to see how people use tactical discourse in their texts to represent themselves and the world in different ways.

Yngre pensionärers informationsbeteende i vardagslivet och på internetkurs.

The aim of this study is to examine the information behavior of younger seniors with a special focus on the Internet. Using a qualitative method consisting of a case study, including observations, diaries, questionnaires, and information diaries, we were able to compare the information behavior of the seniors in their use of the Internet, with the information behavior in their everyday life. The result of the study shows that the respondents led very active lives and used many different information sources in everyday life. They did not only seek information, but also assimilated it, often with a purpose to mediate it to other people. The motives behind the information use in everyday life were mainly connected to their life situations.

EU:s normativa makt inom miljöområdet : En fallstudie om EU:s roll i det globala klimatarbetet

Over the past twenty years, the cooperation within the European Union (EU) has strengthened and expanded with both more number of Member States and stronger influence on international politics. The unique character of the Union and its ability to enforce peace and humanitarian intervention has attracted attention in political science. This prominent position of the Union is perceived by many scholars who often hold this derived from the Union's influence in international relations. Various terms have been used to define the powers of the Union. The British researcher Ian Manners states that the unique identity of the Union in the international arena is formed by its normative power.  An important policy area within the Union is the environmental cooperation.

Olssons trädgård : ett examensarbete som handlar om att lyssna när en plats berättar

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.

En utmanad världsordning- En analys av nya och traditionella biståndsgivares idéer och intressen i det internationella utvecklingssamarbetet

In the past years the traditional donors of development assistance have been increasingly aware of changes in the donor landscape. This as emerging economies like China and India has undergone a transition from recieving aid to becoming emerging donors. By identifying and comparing ideas, beliefs and interests pursued using foreign aid between so called emerging and traditional donors, the greater purpose of this thesis is to take a closer look at the alleged changes in the world order. The starting point is Goldstein & Keohanes framework of the impact of ideas and interests in foreign policy and the one of K.J Holsti about institutions as markers metrics of change. The results show that there is no vast difference in interests but a detectable difference in the ideas behind foreign aid.

Hegemoniska och icke-hegemoniska maskuliniteter - En kritisk diskursanalys av politiska texters och unga m?ns perspektiv p? v?ld i utsatta omr?den

There is a lack of consensus within politics on how to deal with the so-called youth problem that exists in vulnerable areas. The politicians' positions are communicated in speech and writing and influence the majority society's attitude to children in vulnerable areas. Children are at the same time a vulnerable group in society. They are dependent on adults and need their guidance and support throughout their upbringing. In vulnerable areas live children whose health is affected by social and economic vulnerability and discrimination from the outside world. By looking into how hegemonic masculinity as norms are formulated in Swedish political documents, in relation to experiences of stigmatization and violence among children from vulnerable areas, this study wishes to examine if children?s right to a life without violence is being respected in vulnerable areas.

Demokrati ur politikers och ungdomars perspektiv : - En diskursanalytisk studie om demokratiska förutsättningar i Norrköpings kommun

The democratic conditions in national states have change radically at the same time as the society has changed. Because of social and economic globalization processes, the states and government has lost power for the benefit of transnational and global institutions. That affects the democracy since the nation state earlier defined the domain of citizenship. At the same time, citizens? confidence towards political parties and politicians has gone down.

Design och konstruktion av laborationsutrustning till en kraftelektronikkurs

The purpose of this degree project was to build laboratory equipment for a new course in power electronics that starts this autumn 2010 at Uppsala University. The equipment is intended for student labs and it covers the most important areas of the course including rectifying, buck-/boost-converters and PWM-modulation. It is built as one sealed unit where all the electronics are built-in but visible and it has a connection board where students safely can connect the different circuits. The project has advanced from theoretical studies of circuit design, choosing of components and simulations to drawing the printed circuit board (PCB), soldering, case building, final testing and troubleshooting - basically most steps from an early idea to a final product. Measurements on the final product gave about the same results as the earlier simulations of the circuits and the result is overall satisfying..

Fysprofilen hos puckelpiståkare på elitnivå och en jämförelse av fysisk prestation över tid

AimThe aim of the present study was to evaluate physical performance according to ?fysprofilen? in skiers of the Swedish mogul ski team and to compare their physical performance at three test occasions during one year.MethodsAll eight elite mogul skiers at the Swedish national mogul ski team during the seasons 2011/2012 and 2012/2013 participated voluntarily in this study. The test battery ?fysprofilen? was performed at three test occasions, October 2011, May 2012 and October 2012. Muscle strength was evaluated with squats, bench press and grip strength; power was evaluated with power clean, squat jump, countermovement jump with and without arm swing, Harre´s test and the 30 meters sprint.

Europeiska Unionens makt att förändra världen : - En kvalitativ studie ur ett normativt perspektiv

The purpose with this essay was to examine how the European Union is working totransfer norms to states they signed an agreement with and provide support for inframe of the Barcelona process and the Tacis programme. The theory which weused was Ian Manners (PhD in Political Science) theory of "the EU as a uniquenormative power". The aim was to examine whether the EU - which Manners mean- has had a normative power to influence states to change. We used a qualitativeapproach through the use of a multiple case study and qualitative text and contentanalysis. The States which formed the basis of our study were within the BarcelonaProcess; Morocco and Tunisia as well as Azerbaijan and Armenia funded by theTacis programme.

Med samtidsperspektiv på äldre konst : en fallstudie av utställningen "Queer: begär, makt och identitet"

The aim of this essay is to study how older art can be used to illustrate our contemporary society with a critical view and also to contribute to the discussion of for what reason we keep our public collections.My essay is based on a case study of the 2008 summer exhibition ?Queer: desire, power and identity? at Nationalmuseum. The exhibition used art from different eras to show how the ideals, norms of gender, and how the symbols for power have changed throughout history. It also reveals how certain art or artists have been excluded from art history due to their sexual orientation.This study is based on three questions:-          How can older art be used to illustrate a to our society contemporary theme?-          How can a public museum make an exhibition with a clear and active message?-          How can a clear and potentially sensitive message be shown without risking to be provocative towards either the visitors or the person(s) it is about.My material is based on the exhibition, the work material from the museum, protocols, photographs, exhibition texts, and interviews with the creators of the exhibition.

"Nobody never gets to heaven, and nobody gets no land" : En nivåstudie av produktion, struktur, ensamhet och begär i John Steinbecks Of Mice and Men

My main purpose with this paper of John Steinbecks Of mice and men is to both analyze the long-lived structures and the unique individual destinies of the novel. I employ the method of the historical Annales-movement and use three divided levels in my analysis to try to capture these high structures and low moments of humanity in Structure, Konjuncture and the Individuality. The first level, Structure, is used to see how long-lived almost invisible geographic structures set the human act of condition. The second level, Konjuncture, is easier to grasp in understanding of time and embraces for example economic structures as the industrialism. The last level of Individuality is the fastest in time and easiest to understand but in the long run also the least important.
