MÄTNING AV LJUDIMMISSION FRÅN VINDKRAFT. VIDAREUTVECKLING AV METOD FÖR MÄTNING

The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.

Att bo eller inte bo : En studie av tidigneolitisk bebyggelse i Sydskandinavien och på de brittiska öarna

One of the most discussed archaeological subjects is the neolitisation, and the start of a neolithic lifestyle which is characterized by several significant events. The traditional view has been that settled people were cultivating and breeding, but this picture has been questioned and changed in later years. The development is principally based on two models; that already neolithic people immigrated and took over, or that the new lifestyle gradually developed out of the existing cultures. Southern Scandinavia was characterized by a settlement pattern with permanent settlements which were complemented by temporary special settlements, but in time more domestic settlements originated. On the British Isles the settlements didn´t consist of permanent agricultural settlements but instead did the people here move freely between several short term settlements.  .

Sättningsrespons ? en jämförelse mellan resultat från två modelleringsmetoder

Föreliggande studie omfattar en jämförelse mellan sättningsberäkningar med datorprogrammen FEM Design 11 (senast kommersiella versionen) och FEM Design 12 (betaversion under utveckling). I FEM Design 11 modelleras jorden med fjädrar som ges egenskaper motsvarande bäddmoduler, vilka inte på ett helt rättvisande sätt kan spegla jordens komplexa respons vid belastning. Fjädrar kan t.ex. inte överföra skjuvkrafter mellan varandra, vilket får till följd att de enskilda fjädrarnas respons vid belastning är oberoende av varandra. Vid analys av en byggnads sättningar, med ett datorprogram där endast fjädrar (bäddmoduler) används för att beskriva jordens deformationsegenskaper, kan således en helt korrekt bild över jordens verkliga beteende inte återspeglas. I FEM Design 12 kan jorden även modelleras med volymelement, vars egenskaper modelleras enligt kontinuumsmekanik.

"Menniskan, icke naturisk eller djurisk i vanlig låg mening, utan såsom ofvan bildningens strider född till natur och enhet med sig sjelf i himmelsk mening" : Djur som aktörer och bildspråk i Carl Jonas Love Almqvists epik och lyrik

Play is an important part of children´s everyday life, it is through play children develop. Play occurs a lot in kindergarten and in this study, the aim is to examine how play activities play is used in preschool teaching and the role of the teacher´s in the play. Video recordings of play activities done and qualitative methods (conversation analysis) has been used to analyze the video recordings. The results of this study show that play are widely used as a pedagogical tool in preschool. It is through play children develop.

Småskalig säsongslagring av solenergi för uppvärmning av bostäder : Simulering av lagerutformning och konsekvensen av adderade uppvärmningsbehov motsvarande en pool och ett atrium

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest.Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage.

Syftet med studien var att belysa faktorer sompåverkar upplevelsen av smärta och obehag vid en koloskopiundersökning utansedering. Metoden var en litteraturstudie baserad på 19 vetenskapliga artiklar som harkvalitetsbedömts enligt protokoll.

Musik och kunskapsskillnader : -En studie om musiklärares upplevelser kring kunskapsskillnader inom musiken

ABSTRACTMusic and differences in knowledge ? a study of music teachers experiences with differences in musical knowledge. The purpose of this paper is to, out of a music teacher?s perspective, see if the differences in music abilities between 7th grade students are at all, or in some ways connected to the previous schools they?ve attended. I will also research in what areas, in the subject of music, students are differing more, as well as less, in their knowledge. The analysis is based on interviews with six 7th grade music teachers working in the Swedish nine-year compulsory school system.

Förhandlingsbar identitet - en studie av indianerna i USA

In this thesis I discuss and analyze different factors, and different circumstances, that influence identity negotiation among the north american indians. I do this mainly by using two models.The first one is Druckmans three dimensions of identity; negotiating identity, durability of identity and spread of identity. Depending on how the identity fits in these dimensions one can se if, or how, they influence the negotiability.My second model for analyzing is Reeds ?fasteing and unfastening identity?, using this model I have tried to understand during what circumstances the identity is negotiable. The identity is more or less negotiable depending on where the indians live, who they are living with and also on their inheritance.My results shows that the indian identity is changing and developing over time but the main characteristics still remains the same.

Socialization and Identification of New Recruits in Knowledge Intensive Firms: A Case Study

Using the models from van Maanen and Schein (1977) and Dutton et al. (1994), we have been able to investigate the socialization process and organizational identification both from the organizational as well as the individual?s perspective. The link between these two perspectives establishes a better insight into the company?s actual socialization intentions and the individual?s identification with the firm.

Gudsstyre? : En fallstudie av Irans regim

The aim of this Master´s thesis is to examine which type of regime the state Iran is. There has been much research on this issue and the discussion is not over yet. I have departed from three theoretical perspectives in order to understand which type of regime the Middle Eastern nation is: theocracy, democracy and hybrid regime. The theocratic regimetype is composed by David L. Websters archeological theory about governments ruled by God.

Barnfattigdom 2012 : Ett levande problem i Uppsalas skolor

In this essay we aimed to find how economic scarcity among children and youth presents itself in school, according to how school staff experience it. We have conducted interviews with student welfare staff to hear their experiences of this subject and how the schools try to help these pupils. We have used interpretative phenomenology as a base for our work. We have also used some of this traditions most important notions along with notions of Erving Goffman and Sara Ahmed during our processing off the material.  With help from these, we report our most interesting results. We have seen that a lack of resources exists among youth today and that everyone not has easy access to things many of us might take for granted.

Samhällets kropp

The foundation for this thesis lies in whether or not, and how, the body representation in printed commercials, specific products directed to the body (shampoo, body lotion etc.), has changed during the last fifty years. Four years have been chosen because of the changes in society that we believe might have had an impact. The commercials that have been picked out are the ones that best represent the general view of the body. We have found that the changes when it comes to body presentation has followed the social development to a certain degree, but it is difficult to say how much the society has had an affect on the body ideal in advertising. Representations of the male body is something that has escalated since the early 70?s, fifteen years earlier few commercials was made with male models, and the few there were, never showed more than the face.

De klassiska sekulariseringsteoriernas arv : En kvalitativ, komparativ litteraturstudie om Weber och Durkheims sekulariseringsteorier och deras giltighet idag.

The secularization theses has over the last decade been a central issue within the sociology of religion. The two classic theses has been criticized for being one-sided and only focus on the change from traditional to modern society. The intention of this study is to evaluate this critique and to discuss what is defendable in the early secularization thesis in our contemporary world.This essay?s primary purpose is to compare the secularization theses Weber?s The Protestant Ethic and the Spirit of Capitalism and Durkheim?s The Elementary Forms of Religious Life. I use two analytical models, posing three levels and three categories of secularization, in order to make the comparison explicit.

Automatisering av spraytorkningsprocess

ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

"Det blev för mycket Strindberg" : -Lärares resonemang kring sin litteraturundervisning

This study aims to show how teachers talk about their teaching with regards to gender in relation to literature.We have interviewed four teachers of Swedish for upper secondary school to discover how they feel about, and understand, the fact that gender is a factor in the teaching of literature and that they should present to the students literature written by both male and female authors. To analyze the interviews we use Sannersted's (1991) theory about teachers as street-level-bureaucrats ("närbyråkrater"). He states that teachers are persons who have to follow what politicians have decided but they are fairly free to choose how they do it, but to be able to follow a decision as closely as possible three qualifications have to be met. The teachers have to understand the decision, be able to follow it and want to follow it. We find that the teachers that we have interviewed are aware that they discuss gender issues with their students and they all claim that they present a variation of authors to their students.
