Värmning av avloppsvatten med spillvärme för att förbättra kvävereningen -Temperaturens inverkan på kvävereningen

The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.

Effekter av funktionell träning och medicinbollkast för att optimera kinematic sequence och x-factor stretch i golfsvingen

The interest for functional strength training in golf has grown the last decade and scientists are always trying to find training stategies to improve the biomechanical aspects of the swing. Kinematic sequence contains a proximal-to-distal sequence order towards impact, and an effective kinematic sequence in the down swing begins with a rotation in the pelvis and follows by an activation in thorax, arms and club in the respective order. The rotational torques in the proximal segments wanders through the body and to the more distal segments to create an effective energy ? and power transfer at impact. The x-factor stretch is the seperation between the rotation in the pelvis and the thorax at the top of the back swing and at the beginning of the down swing.

Passivhus ur en brukares perspektiv

 Ett passivhus är ett hus som i stort sett enbart värms upp av människorna och elapparaterna som finns i huset. Särskilda krav för att få kalla huset för passivhus måste uppfyllas.Vi har gjort en enkätundersökning på tre olika passivhusprojekt för att utreda vad de boende tycker om inomhusklimatet. De utvalda projekten finns i Värnamo, Frillesås och Glumslöv. Enkätsvaren visar att de boende i Frillesås är mycket nöjda, medan mer än 50 % av dem som bor i Glumslöv tycker att det är för varmt på sommaren och för kallt på vintern. För att utreda om de olika konstruktionerna har någon inverkan på inomhusklimatet har beräkningar och simuleringar i datorprogrammen VIP+ och IDA gjorts.

"Lite snyggare, lite mer partyaktiga, lite mer Paradise" : En kritisk diskursanalys av kön och sexualitet i Paradise Hotel

The purpose of this thesis is to examine how power structures concerning gender and sexuality emerge through the use of language in the Swedish reality show Paradise Hotel. Of particular interest is the representation of heterosexual relations in the show. Because of its interest in the relationship between power, gender and sexuality, the thesis is based on theories from gender and discourse studies. The specific theories referred to are Michel Foucault?s understanding of power, stereotypes according to Stuart Hall, Yvonne Hirdman?s gender system and contract theory, Judith Butler?s heterosexual matrix and R.W.

Utvärdering av trafiklösningar och markanvändning på Södra Älvstranden i Göteborg

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Att definiera omsorgsbrist : En kvalitativ studie om socialsekreterares tolkningar av 2 § LVU utifrån intersektionalitet och makt

This study regards the Care of Young Persons Act, LVU, and the 2 § that focus on parent inability to care for their children. The assessment of parent ability to care for their children is performed by social workers in different municipalities. The law leaves room for interpretation concerning how to assess parent ability and therefore we found it interesting to study how social workers interpret 2 § LVU. The study?s aim was also to seek an understanding of how different categories, like gender, race, class and physical and psychical ability of the parents affect the assessment of their parenting ability, with a intersectional perspective.

Nekande tvångsmakt i Operation Unified Protector

There are several competing views on how to best utilize air power. Following his quantitative study of air power, Robert Pape developed a theory which focuses on undermining the target state's military strategy. According to Pape it is possible to explain the outcome as a result of military vulnerability. This essay seeks to determine if Pape's theory can predict the outcome of Operation Unified Protector. By using a mixed methods approach on four hypotheses, it will be determined if the operation was a successful case of coercion, if NATO acted according to Pape's model and whether this achieved the desired effects or not. The results reveal that the theory could not successfully predict the outcome of the conflict.

Kampen om dagordningen : Kan media anses vara en enskild politisk aktör

Abstract Essay in political science, C-level, by Patrik Larsson, autumn semester 2007.Tutor: Susan Marton The battle over the agenda-Can media be regarded as an individual political actor? The purpose of this essay is to study to what extent media can be regarded to function as an individual political actor. In other words, do the media have more power over the political agenda than the politicians and do the media influence how the politicians make their decisions. This research is a case study and to be able to complete the intention of this study I have used Maxwell McCombs and Donald Shaws theory, the agenda-setting theory. From this theory I have used four aspects to analyse my material which has consisted of editorials from a Swedish newspaper, interpellations and debates that belong to the interpellations. The aspect I have worked with are, how the problem is defined, who is responsible for the problem, what values and which solutions are expressed.  I have used a qualitative text analysis as my methodological approach which means that the results of my study are my interpretation of the material. My conclusions are that the media in this case shouldn?t be regarded as an individual political actor because there is no tendency that shows that the media has influenced the government in their decisions concerning the real-estate tax.

Konstruktion och byggnation av testfixtur för 10Gbit/s transpondermoduler

This thesis for the Master of Science degree was performed at Solectron Corporation in Norrköping. The background for the thesis was a need to develop and build two test fixtures to automatize testing and adjusting of transmitter modules (TX-fixture) and receiver modules (RX-fixture) which are head devices in DWDM-systems. The basic elements for the test fixtures are: Test board, switch board and DC/DC board. The main function of the test board is to handle communication between the transmitter and receiver modules and supply voltage to these modules. The test board was insufficient and modified with a microprocessor to handle the communication between the PC and the receiver module.

Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal

Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

En diskursreglerad v?rld: Makt, kunskap och agens i Mark Lawrence? The Book That Wouldn?t Burn

Historically the library has owned more than silent, book-filled halls; it has been a center for learning and ideas, a source of both freedom and oppression, in other words, a medium for knowledge, truth, and power. Cultures have been divided into powerful and powerless through access to the library's content; those who have - and those who do not have - access to information determine which voices are heard and which are ignored, thus determining the outcome of the future. This thesis investigates how The Book That Wouldn't Burn by Mark Lawrence portrays the relationship between knowledge and power using Michel Foucault's discourse theory. More specifically, how this relationship is manifested through the structures and norms of society, and how the library as a place and institution serves as the means by which this relationship plays out. An established classic like Fahrenheit 451 by Ray Bradbury is placed as a contrasting reference point to help deepen its thematic message of information control and cencurship. Furthermore, the agency of one of the main characters is also examined in the light of Anthony Giddens' stratification model, as an actor with the potential to move beyond the confines of the power structure. The analysis demonstrate how knowledge, truth, and power remain continuously thematically relevant within literature, and how the reality of our time may be better understood through literary contributions.

Utomhuspedagogik : Hur pedagoger arbetar med naturvetenskap utomhus

The aim of this study is to understand which strategies helped women escape honourbased violence, by reading the autobiographies of seven women. Honourbased violence is a relatively new problem in Sweden, but it has existed for a long time. According to FN (2012) 5000 women are murdered every year in the name of honour. Honourbased violence is about maintaining the honour of the family. Womens sexuality is connected to men´s honour, and because of that they are not allowed to express it.

Våra sociala medvetanden: En diskussion om ett socialt perpektiv angående medvetandet

In this essay a social perspective on the mind is explored and argued for. The essay moves from a discussion of a social collective foundation for the individual mind to a discussion ofthe main alternative ways of describing the shared social world, namely an action-centred perspective and a power-centred perspective. It is shown that these two perspectives are combinable. A combination of the two perspectives is therefore recommended for a more balanced way of describing the shared social world. In this essay it is argued for that the individuals? mind and her identity is dependent on the surrounding community.
