Utvärdering av beräkningskoden APROS för användning i inneslutningsanalyser

At Forsmark nuclear power plant the rather old-fashioned software COPTA is used in containment safety analysis. There exists a desire within the organisation to introduce a more modern software with ability to more detailed modeling and increased usability.The goal of this thesis was to evaluate the software APROS in containment safety analysis. APROS models describing one of the containments at Forsmark NPP have been developed. Two simulations of typical containment incidents, one of them a large pipe break, have been made where containment safety parameters such as pressure and temperature are studied. Results are analyzed and verified against results from corresponding COPTA models.

Attityder till förändring : effekter av decentralisering. En studie av anställda i ett detaljhandelsföretag.

Background: The Swedish retail trading company KappAhl has reorganized all the boutiques in Sweden. Before the reorganization many of the boutiques consisted of four levels: shop manager, assistant shop manager, department managers and regular personel. After the reorganization assistant shop managers and department managers have been replaced by a so called ?responsibility group? consisting of some of the employees. The change is presented as a decentralisation.

Nordiska Fondbolags riskjusterade avkastning : En jämförelsestudie av fondbolag verkande inom tillväxtmarknader

The purpose of this paper is to examine and analyze past development of mutual funds in large and small mutual fund companies and see if there are any differences between these two segments. Limitations on the number of funds have been made by choosing Nordic mutual fund companies that invest in emerging markets over an 11-year period. The study is made on 66 mutual funds managed by 13 mutual fund companies in which the segment of small fund companies includes seven fund companies with assets under management less than 100 billion SEK and the segment of large mutual fund companies includes six fund companies with assets under management more than 400 billion SEK. In the comparison of the segments the Sharpe ratio has been used to calculate the risk-adjusted return. The study shows small differences of the risk-adjusted return between the segments.

Modellering och reglering av drivenheter i gaffeltruck

To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.

Välbefinnande och sexualitet för kvinnor i en parrelation. : En fenomenologisk intervjustudie.

The aim of the study was to focus on well-being and sexuality for a woman in a couple?s relationship. Seven women were interviewed and the analysis was carried out with a phenomenological approach based on lifeworld theory. The respondents reported their lived experiences of well-being. The result is summarized in five constituents: the relationship?s common living-space, looking for companionship, the relationship as touching, the intimacy of the relationship and the importance of other people for the relationship.

Miljöberikning för grisarnas välbefinnande : Bökboxen -  en prototyp för att motverka stereotypa beteenden hos grisar

The demand för Swedish pork meat is increasing every day. This leads to agricultural farming having to develop as an industry, with larger and more rationalised units to make the farming more effective and to raise the financial profit. The consequence of this is that it affects the animals when their surroundings become more industrial. The pig´s natural behaviour becomes restricted by the Limitations of the facilities, which leads to them becoming understimulated. Helena Kummel, a teacher at Munkagård upper secondary school and also an educated animal inspector has developed a prototype that could possibly replace the pig´s natural rooting behaviour inside the barn. The porpuse of this report is to study "bökboxen" in the gilts´actual living enviroment, through qualitative- and quantitative analysis.

Distribuerade fastighetsautomationssystem : - En implementation av kommunikationsprotokollet BACnet

Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

Skrivförmåga hos vuxna med intellektuella eller kommunikativa funktionsnedsättningar inom daglig verksamhet

The aim was to examine writing ability and some of its underlyingfunctions in adults with intellectual or communicative disabilities at dailyactivity centres by comparisons with children and adults without disabilities.66 adults with intellectual or communicative disabilities, 39 children and 14adults without disabilities were included. The following tests/tasks wereexecuted: Test for Reception of Grammar-2, graphomotor task, nonwordrepetition, Rapid Automatized Naming and Writing elicited by pictures. Thepicture elicited narratives were examined regarding length, spelling,syntactic complexity, interpunctuation, content and general impression. Theresults demonstrated that adults at daily activity centres performed lowerscores than adults without disabilities. The group generally didn?t differ fromthe children, but they made a smaller proportion of phonologicallyacceptable misspellings and achieved lower scores on nonword repetitionand Rapid Automatized Naming, which could indicate Limitations inphonological processing ability.

Radomoptimering för luftburna störsändarkapslar

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and Limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..

Femininitet/maskulinitet och lesbisk identitet. En queerteoretisk studie och berättelseanalys av Tjejerna mot strömmen och Såna som oss.

AbstraktDenna studie handlar om förhållanden mellan femininitet/maskulinitet och lesbisk identitet med bakgrund av den heteronormativa genusordningen, vilken grundar sig i ett dualistiskt tänkande där kvinnor som feminina respektive män som maskulina attraherar och kompletterar varandra. Studien bygger på berättelseanalys av personliga berättelser skrivna av lesbiska kvinnor ur antologierna Tjejerna mot strömmen och Såna som oss, vilka tolkas utifrån en konstruktivistisk ansats och ett queerteoretiskt perspektiv. På detta sätt synliggör och problematiserar jag konstruktioner av lesbiska självrepresentationer och identitetsskapanden samt de möjligheter och begränsningar som dessa identiteter omringas av med bakgrund av den heteronormativa genusordningen. Utifrån detta kommer jag fram till hur de lesbiska subjektpositionerna öppnar upp för alternativa identiteskonstruktioner och begärskonstruktioner i relation till aspekter av femininitet och maskulinitet. Vidare resulterar analysen i ett framhållande av den osynliggörande tolkningen av lesbisk femininitet i termer av heterosexualitet samt den osynliggörande förståelsen av lesbisk maskulinitet som ett kopierande av manlighet och manlig maskulinitet.

Tidsperspektiv som prediktor för individuella skillnader i upplevd stress : En tvärsnittsstudie av äldre vuxna

Time Perspective is related to mental and physical health. This study examines the relationship between Time Perspective and perceived stress where Time Perspective was expected to predict the level of perceived stress. Past-negative, Future-negative, Future-positive and present-fatalistic were expected to be positively associated with perceived stress while Past-positive and present-hedonistic were expected to be negatively associated. Measures from the self-assessment forms S-ZTPI, PSQ-recent and CES-D from 445 participants (242 women, 203 men) between 60-90 years were used to examine the hypothesis of the study. Two hierarchical multiple regression analysis confirmed that Time Perspective is associated with perceived stress and in part 2 explains it's variance, one when adjusting for demographic data (.R = .37) and the 2 other when adjusting for demographic data and depressive symptoms (.R = .13).

Att leva med en inflammatorisk tarmsjukdom

Background: Inflammatory bowel disease (IBD) is an umbrella term for ulcerative colitis and Crohn's disease. These are characterized by a chronic inflammation of the intestinal mucosa. Living with chronic illness meant that life changed significantly. Quality of life was affected for these individuals and was stressful in their lives. Aim: The aim was to describe the experiences of living with inflammatory bowel disease. Method: A qualitative literature review was chosen to analyze articles that were related to the aim of this study. Results: Based on the chosen articles five themes were created; Commuting between hope and fear, symptoms of the disease and medication become everyday focus, struggling with  the new identity, desire to control the disease- do I control my illness or does it control me and social relationships are affected. Conclusion: Inflammatory bowel disease is a distressing disease and can cause Limitations in social life due to lack of knowledge by others about the disease. The affected felt a loss of control in their life due to the difficulty in managing the symptoms.

Vattenskydd och krisberedskap hos allmän dricksvattenproduktion : Skydd av täkter, tillgång till reservvattentäkter och andra nödvattenlösningar hos svenska vattenproducenter

The objective of this report was to analyse and compare vulnerability and preparation in Swedish municipal drinking water production, in case the commonly used water sources were inoperative. Methods used were a questionnaire and a less extensive study of regulations for water protection areas. The questionnaire was answered by 41 Swedish municipalities. A handful of them were companies co-owned by a few municipalities. Only one out of four municipalities had source protection areas to all their water sources and for many sources the protection was not satisfactory.

Test av icke-kurssäkrad ränteparitet med fokus på riskpremien och möjliga förklarande faktorer

This thesis aims to evaluate the concept of Uncovered Interest Parity. The parity states that the logarithmic difference between domestic and foreign interest rate equals the logarithmic difference between expected future spot exchange rate and the spot exchange rate, . In defining the exchange rate it is often presumed that the parity relation prevails even though several studies suggest the opposite. Numerous economists maintain that the theory?s shortcomings can be explained through the existence of a Risk Premium.
