Det regionala partnerskapet - ett verktyg för Skåne att samverka?
Because of a more globalised world the national states have been forced to make structural changes at both national, regional and local level to cope with different challenges. The regional community has become an important area which has resulted in a policy of more self governing, both for the regional and the local level.The aim of the thesis is to study the relation between regional and local level in the partnerships organisation. To fulfil the aim of the thesis, a case study of Region Skåne is used. The analyse is based on expressions such as cooperation, conflict, power and influence.The result of the thesis confirms that the opinion between the regional and the local level is very different. The representatives from Region Skåne experience the cooperation as quite good because it creates an opportunity for discussions and a possibility to learn from the other actors which in turn creates a qualification in the exchange of knowledge.
Påverkar euron resultatet av stabiliseringspolitiken? : En studie av stabiliseringspolitikens utfall i de nordiska länderna sedan eurons tillkomst, och av betydelsen av en nationell penningpolitik.
This paper discusses whether the main argument for European countries to stay out of the euro, i.e. the loss in stability from not having a national monetary policy that can be used for stabilization purposes, is still valid ten years after the introduction of the single currency. We analyse the stabilization performances of four largely comparable Nordic countries that have all chosen different levels of European economic integration. In retrospect, the so-called ?stabilization policy argument? seems surprisingly weak.
Strömkontroll till aktiva magnetlager med noggrann och störningsreducerad strömmätning
There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).
Transient kallstartssimulering i GT-POWER
Etanol är ett intressant bränsle för framtida motorer där låga emissioner och bränsleförbrukning blir allt mer relevant. Etanol är både förnyelsebart och har intressanta förbränningsegenskaper med ett högt oktantal och snabb förbränning. Användning av förnyelsebara bränslen reducerar utsläppen av koldioxid samt medför att vi inte längre behöver förlita oss på de fossila oljedepåerna.En egenskap hos etanol är att bränslet kräver mycket värme för att förångas. Det medför att kallstarter blir ett problem då det är svårt att få bränslet att förångas och antändas då motorn är kall. Kallstartsförsök har gjorts på en direktinsprutad encylindrig motor med skiktad förbränning.
Sura Gamla Kyrka : analys av patologiska och skeletala förändringar hos sju individer
Seven individuals from Surahammar in Västmanland Sweden are analyzed for the appearance of pathological and skeletal changes. The graves, all from within the walls of a fourteenth century church, are dated from the Viking age to late eighteenth century. The aim of this scientific essay is to find pathological conditions by doing an osteological analyze, x-ray analysis, an osteoporosis measurement and letting orthopedists assess the individuals. The aim is also to say something about the individuals? general health and how they experience the changes they have in the skeleton.
Vägen till framgång : En semiotisk analys av Tv3s representation av myten om det goda livet.
In the research field of the cultivation theory focus has shifted from TV in general to studying specific genres instead. It is proposed that there are similarities in otherwise different shows and that these shows give it´s voyeurs a solution to their problems. The purpose however of this study is to investigate how the myth about the good life is posed in Tv3´s supply. The theories used in this study are closely linked by their meaning. Narrative talks about the fact that texts, video in this case, contain stories. Ideology is the set of visions and beliefs one person has on the world and myth makes social, historic and cultural decided power orders in to facts.
Projektering av ett småhus med fördjupning i uppvärmningssystem
This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.
Deaktivering av metanisering katalysatorer
A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.

Pedalkraft system : Stödsystem för elproduktion i småskalighet
Detta examensarbete vänder sig till personer som är intresserade att använda nya miljövänligametoderna för elproduktion eller personer som redan använder små vindkraftverk ochsolpaneler med behovet av en extra energikälla i små stugor eller avlägsna platser där tillgångentill elnät är omöjligt. Syften i detta arbete är först och främst att bygga ett system förelproduktion med hjälp av en cykel. Sedan bestämma mängden av elektrisk energi en personkan alstra med systemet. Slutligen svara om detta system skulle kunna använda som ettstödsystem för elproduktion i småskalighet.Den första målsättningen är att utforma ett system med användning av kraftelektronik där denkraften som genereras matar lasterna. Den mekaniska delen kommer att konstrueras som en delav energikällan, därefter kommer det att utformas en kontroll för att styra effekten viaelektroniska komponenter, de elektriska belastningarna matas av systemet, kommer attsimuleras.
Viljan att veta : en analys av Mona Hatoums verk Corps étranger via bio-politik och science fiction
In this paper Mona Hatoums installation Corps étranger is discussed via a post structuralized method based on associative and semiotic comparisons with vanitas, a post-modern self-portrait, and as a representative for modern visual art. The analyze touches upon pornography, science fiction and the quest for scientific conquest in outer and inner space. Theoretical references are Foucault, Freud, Lacan, Barthes, Dolar, Said and Virilio. Hatoum makes the observer a voyageur with the aid of the latest medical technology, endoscope, which gives her the opportunity to make an introvert self-portrait when she films her own throat and rectum. But at the same time she makes the portrait of us all.

"Jag vägrar sätta in mig i en norm!" : En studie av "BRYT! - ett metodmaterial om normer i allmänhet och heteronormen i synnerhet"
In this essay I examine how the norm-critical material ?BRYT! ett metodmaterial om normer i allmänhet och heteronormen i synnerhet? is used by Hyresgästföreningen in Stockholm in their education of personnel in the perspective of equalisation. I?ve mostly been interested in how the personnel who takes part in workshops about the material react and reflect in relation to the purpose of the material. How do they discuss about norms and the connection to discrimination and how do they look upon the power and responsibility that comes with power in relation to norms? Earlier research in norm critical pedagogy and the critic of tolerans pedagogy perspective helps me to analyse how critical pedagogy stands above non-critical pedagogy in many perspectives.By observing workshops and by interviewing personnels taking part in these workshops I?ve examined how they react on both the practical and theoretical parts of the material.To summarise my examination I find the personnel who is educated in working with the material discover new experiences in knowledge and on how norms and discrimination functions.
Kovariansskattningar vid portföljval - Utvärdering av fyra alternativa metoder för att skatta kovariansen
I denna uppsats beskrivs och implementeras tre alternativa metoder för att skatta kovariansen mellan finansiella tillgångar. De utvärderas sinsemellan och jämförs med stickprovskovariansen. Utvärderingsmodellen innebär simulering av en aktiv portföljförvaltare i en verklighetstrogen miljö. Då kovariansen mellan finansiella tillgångar beräknas med stickprovsskattning blir skattningsfelet stort. Detta fel, eller brus, försämrar portföljförvaltares resultat och alternativa metoder eftersöks.
Den allsmäktige kunden : En kvalitativ studie om word-of-mouth, viral marknadsföring och viljan att dela med sig.
The purpose of this thesis is to clarify the connection between word-of-mouth and viral marketing, to identify properties of and strategic ways to implement viral marketing and to examine how a company can influence the customers? perception of the brand in social media.This purpose served to answer our research question: How can companies deliberately create viral marketing?To answer this question we based our study on a qualitative method where we conducted eight interviews with different people, all with experience in our research field. We focused on our respondents? own opinions and were more interested in their personal experiences rather than the market in general.In our last chapter our analysis clearly demonstrates that companies can deliberately create viral marketing. This is possible if companies create material that appeal to and that triggers the costumer to share.
