Kvantifiering av osäkerheter i lyftkraftsmodellen

With today´s power uprates in BWR reactors the bundle lift force has become aproblem. The lift force is calculated using a best estimate approach and the resultfrom the calculation should pass the existing lift force margin. Lift force margin isdefined so that the lift force may not exceed 80 % of the fuel weight. The margin issupposed to cover all the uncertainties that exist in the lift force calculations.However, no uncertainty analysis has been conducted to quantify the uncertainties.In this report the uncertainties in the lift force model have been quantified. Each inputparameter to the lift force model which has been assumed to have an uncertainty isassigned a probability distribution.

Att synliggöra de osynliga : En analys om fyra kvinnliga irreguljära immigranter och om hur deras relationer till andra människor påverkar deras livssituation och identitet

The objective of this paper is to describe and analyze female irregular immigrants and their experience of how relationships with other people affect their lives and identity.A qualitative method is used in the study, because my main purpose is to analyse the respondents? lives and life experiences. The analysis is based on a symbolic interactionism perspective. The results are also analyzed based on previous research and the concepts underlying the paper; irregular immigrants, discrimination, power and identity.In summary, the respondents have a clear picture of how they live and experience their relationship to others and themselves and how this affects their lives and identity.Their experiences affect their lives and influence their behaviour and identity when they interact with others. Their own view of their situation means that they are afraid to seek care or report sexual abuse, threats or other similar conditions.

Den permanenta krisen : En narrativ studie om orsakerna till det första kriget mellan Ryssland och Tjetjenien

"Här hymlar vi inte om sånt" : Synen på arbete och klass i Stig Sjödins Sotfragment och Jenny Wrangborgs Kallskänken

The purpose of this thesis is to examine how the public libraries work towards SFI (Swedish For Immigrants) based on the views of the overseeing librarians. To study this we have asked the following research questions:What distinguishes the public libraries? work towards SFI according to the responsible librarians? What distinguishes the communication between SFI teachers and the librarians according to the responsible librarians? What opinions are held by the librarians in regards to their work with SFI?We have used a semi structured interview method with seven librarians in charge of the activities with SFI at small and medium sized public libraries in a rural area of Sweden. The theoretical framework is composed of Marianne Andersson and Dorte Skot-Hansen?s model for analysis of the local public library profile and the authors? definition of collaboration.

Mjuk massage och diakoni : Ett holistiskt perspektiv

IntroductionTactile Massage is a generic term that for example includes Massage therapy, Effleurage, Gentle touch, Tactile stimulation, Soft massage and Aromatherapy massage (SBU 2009). Tactile Massage has been proven to activate the perception receptors of the body and stimulates the system of oxytocin and in that way Tactile massage increase wellbeing and decrease pain. The Church of Sweden was formally separated from the state in the year of 2000 and by this means created greater freedom in facilitating its own social and Deaconal programs in separate parishes. Since 2004 a few numbers of deacons have been integrating Tactile massage as a method in Deaconal  ministry within the framework of holistic care in the Church of Sweden.Aim/Research questionsThe aim: From a holistic perspective investigate the use of and to increase the problem-awareness of Tactile massage in the Deaconal ministry within the Church of Sweden.The research questions: How is Tactile massage being used and how are we to describe the experiences of Tactile massage in the Deaconal ministry? What possibilities and difficulties are related to the use of Tactile massage in the Deaconal ministry within the Church of Sweden?MethodThis study is the first explorative research about Tactile massage in Swedish church diaconal context.

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.

Manliga vampyrer och kvinnliga offer. En diskursanalys av det övernaturliga och könsroller i The Vampire Diaries

The purpose of this essay is to examine how the supernatural and the occult are portrayed inpopular culture. To be able to do this, I have chosen to perform a discourse analysis of the twofirst novels in the L. J Smith series The Vampire Diaries. The novels are called TheAwakening and The Struggle.I apply the following questions in my analysis to narrow down the perspective further.?In what situations are supernatural used in the books and what part does it play??How does the supernatural affect the main characters and how is this portrayed in the novel??How is the supernatural portrayed depending on the gender of the character?I will focus mostly on the vampires since they generally are the ones who introduce thesupernatural elements into the story.I am applying gender theory in my discourse analyses of the novels, to hopefully be able togive a wider picture of the supernatural in relation to gender in the novels.I begin with analyzing the main discourses in the story, revolving around the supernatural.Secondly I analyze what impact the supernatural has on the main character.

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.

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.
