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.

Ontologier i kunskapsorganisation Vägen från tesaur till den semantiska webben

This thesis aims to analyse ontology, primarily as the word is used in the context of the Semantic Web. One of the main questions is how ontologies relate to classification and thesauri, two concepts well known within Library and Information Science. The vision of the Semantic Web, a more intelligent addition to the current World Wide Web, has raised the question of how to deal with information scattered over a multitude of locations, stored in different formats, written in different languages et cetera. This issue is in many ways similar to the classical problems encountered in library science: how to classify and categorise large amounts of information. The use of ontologies is one of the main steps leading to the Semantic Web, as well as a tool which can be used in other areas of information organisation and management.

Matningssystem för pellets

In today's society, the availability of energy plays an integral part in our everyday lives. Unfortunately, the price of energy in Sweden has increased in recent decades. A large part of our energy consumption goes to heating modules for houses, where heating methods that depend on energy sources such as electricity, district heating, fuel oil, gas and biofuels are the most common ones. During the winter period, the increase in energy costs becomes significantly evident, especially for small property owners. This increase in energy cost is most noticeable for home owners with electric heating.This thesis is written at the Halmstad University, in cooperation with a company, which makes parts of this thesis confidential.

Särskilt ömmande omständigheter -ensamkommande barns bästa? : Om regleringen kring ensamkommande barn som anknytningspersoner i förhållande till FN:s barnkonvention

AbstractMany of the refugees around the world today are children. Some of these children are travelling alone without anyone looking after them. These children flee from their countries to save their lives and as they are children they need special care and protection. This thesis has investigated the protection given to unaccompanied children during the asylum process in the two key instruments in the area: the Convention of the Rights of the Child and the Convention Relating to the Status of Refugees. The Refugee Convention does not contain any procedural rights and does not specifically acknowledge children, even though they are included in the scope of the Convention.

Fast i garderobsöppningen : En kritisk diskursanalys av VeckoRevyns representation av bi- och homosexuellas sex- och kärleksrelationer

The purpose of this study was to examine the ways in which the Swedish lifestyle magazine VeckoRevyn construct the sex and love relations of bi- and homosexuals. We analyzed 22 unique texts in magazines, from 2009 to 2014, in order to get a result as current as possible.To represent the magazine overall we have selected texts from various parts of the magazine. With a critical discourse analysis and through relevant and significant theories and perspectives such as social constructionism and heteronormativity, we found that VeckoRevyn represent sex and love relations of bi- and homosexuals through four discourses.The outcome of our study shows that VeckoRevyn only represent a limited part of bi- and homosexuals sex and love relations. In the analysed texts bi- and homosexuals are forced to ?come out of the closet? repeatedly and their sexual relations are rarely represented.

Hörselnedsättning hos för tidigt födda barn ? En litteraturstudie

A stay in the neonatal intensive care unit of greater than 5 days is one of the identified risks ofa sensorineural hearing loss. Preterm infants usually have at least one risk factor for hearingimpairment. The period from 25 weeks' gestation to 5 to 6 months of age is most critical tothe development of the auditory system. We think it is important to investigate hearingimpariment among infants born preterm, degree and type of hearing loss, risk factorsassociated with hearing loss and how the auditory system may be affected by preterm birth.ObjectiveA critical review of the current literature including studies of preterm infants born betweengestonal age 25-37. Our aim is to identify the most common type and degree of hearing lossamong infants born preterm and if there is an association between hearing loss and pretermbirth.MethodA literature search of Scopus and Pubmed resulted in 16 articles from 2000-2015ResultsMost of the infants in this study had a severe to profound sensorineural hearing loss.

Vi döpte om biblioteket till Bibliotek and läranderesurser: Om imageskapande på högskolebibliotek

The aim of this thesis is to examine how four decision makers at a University College and a library director at the same University College perceive the profile, image and identity of their library. This University College library is used as our main example. We have evaluated the main example in relation to two other University College libraries, in order to obtain a deeper understanding of how these library directors view their own libraries and to attain a more multi-dimensional view of the main example of our study. Our intention is to analyse the current situation, not the past nor the future. Qualitative semi-structured interviews with decision makers and library directors have been conducted.

Att skola mångfalden ? ett nationalistiskt försök : En analys av sverigedemokraternas diskurs om det goda samhället och den goda skolan kopplat till skolansvärdegrund

This essay attempts to examine the discourse of the Sweden democrats in relation to thevalue system of the Swedish national school.To analyse the political texts I use discourse analysis and especially the method and approachconducted by Judith Lee Bacchi. Bacchi focuses on the construction of a problem in variouspolitical discourses. When performing this kind of analysis the main question is (accordingto Bacchi): ?What is the problem represented to be??I find that the Sweden democrats construct the ?migration politics? and the ?multiculturalpolitics? that is guiding the society as the cause of most problems in our society. To solvethe ?problems? they promote a nationalistic and a cultural racist discourse especiallypinpointing the ?Muslims? as being a problem.Since the Sweden democrats are striving to implement their discourse in the society andschool, and since their discourse already are reproduced by solar students in the classroom,I find it important to examine the essence of their particular discourse and contrast it withthe current value system of the Swedish schools.I don´t find the nationalistic and racist discourse of the Sweden democrats to correspond tothe value system of the Swedish school, mainly due to their strive to create alienation, andby labeling individuals in a reductive manner, instead of using apparent differences as asource for democratic discussions in the classroom.

De internationella musikbolagens redovisning av immateriella tillga?ngar : Vad kan de svenska bolagen tilla?mpa i jakten pa? ra?ttvisande bild?

Purpose:The purpose of this study is to describe and explain the international music company reports of its intangible assets to examine whether similar methods can be applied to the Swedish market.Method:The study was based on a qualitative and abductive research approach. Collected data is mainly from secondary sources in the form of auditor approved consolidated financial statements.Conclusion:The Swedish music companies activate their intangible assets only partially or not at all, despite the fact that assets in the form of music catalogs, rights, contracts and advances are those that generate revenue for the companies. The study has resulted in a description of how the companies are doing on an international level with the IASB and FASB's regulation. With this report, we have found flaws in the way the Swedish companies prepare their accounts according to the current regulations. In the analysis, these shortcomings are highlighted and to what extent these international standards can be applied in the Swedish companies to take a step towards a more accurate picture and a harmonized and comparable accounting..
