This paper investigates decision-making under uncertainty and complexity. The focus point of the study was to investigate how organizations in Stockholm has come to a decisions on how to manage the trial implementation of a congestion tax in terms of their company cars. The study was conducted as a survey with complementary interviews with the decision makers in change of congestion tax problem. The aim of the study was to gain an understanding for the decision making processes, and how and why the companies decided as they did. The theory on which we based our study emanated from both systems theory and business economic theory on decision making.

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

This paper gives an introduction to the theory of minimal surfaces. It is in- tended for undergraduate students with some basic knowledge of differential geometry and complex analysis.After defining the concept of minimal surface and giving a brief histo- rical survey, we look at some well-known minimal surfaces and a few of their characteristic properties. The connection between minimal surfaces and harmonic functions is discussed and the Weierstrass-Enneper represen- tation formulas are introduced. We also present Bjo?rling?s problem and give some examples. .

Syftet med denna studie var att beskriva föräldrars erfarenheter av problem med aktivitetsutförande i skolan för barn med ADHD. För att uppnå syftet med studien tog författarna del av tidigare inspelade djupintervjuer med fem föräldrar till barn med ADHD i åldrarna 6-18 år. Vid hantering av data tillämpades kvalitativ innehållsanalys med en induktiv ansats för att analysera föräldrarnas erfarenheter. Analys av data resulterade i följande kategorier: ? Problem i sociala interaktioner hindrade aktivitetsutförande?, ? Den fysiska miljön begränsar aktivitetsutförandet?, ?Institutionella brister hindrar aktivitetsutförande?.

Syftet med studien är att kartlägga och utvärdera IT-stödet inom institutioner tillhörande den samhällsvetenskapliga fakulteten vid Uppsala universitet. En fallstudie har genomförts som resulterat i en verksamhetsdiagnos som utgör en summativ utvärdering av IT-stödet för grundutbildningen. I denna utvärdering beskrivs problem och styrkor med IT stödet ur ett verksamhetsperspektiv. Studien visar att IT-stödet (e-infrastrukturen) på lokal nivå inom Uppsala universitet är komplex, problematisk och att den har en skiftande kvalitet. Undersökta institutioner har olika behov och krav på IT-stöd.

The purpose of this study is to investigate how the Swedish newspaper Sportbladet watches over the Olympic games in Sotji, 2014. This study aims to find out why certain topics is more popular writing about and why others are not. The study also analyses the news distribution in terms of gender and nationalism.To find answers to this questions, a quantitative content analyses was used.  The results is based on 220 texts collected from eleven days news reporting in Sportbladet. Ice hockey and cross-country skiing was, without a doubt, the most popular sports according to news, interest and reporting. These two sports occupied a great deal of space in the newspaper and also had most articles.Furthermore, this study shows the domination of men amongst news pages according to both space and frequency in Sportbladet during the Olympic games in Sotji. In spite of that fact, women was assigned more space in the news paper throughout the Olympic games compared to the daily reporting.

Recent studies show that the knowledge in and understanding of science, technology andmathematics of Swedish junior high school and high school students is decreasing. As a resultof this the Swedish government has initialized several studies, research and reforms. One ofthe theories for teaching that today is seen as effective is the socio-cultural perspective and itsdescendants, including scientific inquiry. Using the pedagogy of the socio-cultural perspectivefour assignments regarding the human body was constructed for junior high school studentsattending summer research school in the summer of 2008, hosted by AstraZeneca. Theassignments follow a structure (goal of assignment, preparations, experiment and follow-up)inspired by the concept of NTA ? Naturvetenskap och Teknik för Alla (Science andTechnology for everyone).

The purpose of this study is to examine the accessibility with public transportation in the case of the Umeå Region in northern Sweden. This is done by GIS network analysis where both access to transit stops, as well as access by public transport from stops to destinations is examined. An accessibility index is created from transit frequency and travel times to destinations. The results is compared with population register data to calculate what shares of the population has which levels of accessibility with public transportation. In the Umeå Region there are different levels of accessibility by public transport for different parts of the region, where transit stops in the most densely populated areas has the highest levels of accessibility, as well as stations along the railroads.

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

This assignment focuses on the concept of ?school trips? and Gotland. Pedagogically, the school trip was initially focussed on practical and national aspects, the education to be made visible and the idea was to present Sweden, its nature and its industries. The Gotland administration chose to focus on the unique and cultural history, and it was unusual that visits were undertaken to factories and workshops. This was also the start of the current tourism trend where knowledge of the value of the countryside and the opportunities for tourism is a successful combination, which can be seen today even if the school trips now have different areas to visit.

This thesis is about cover illustrations of DVD movies as examples of visual communication. I have studied the cover illustrations of the three movies Gran Torino, Secret Window and As White As Snow. My research assignment has been to find out how the cover illustrations of DVD movies communicate in relation to the story. I have also been looking for what makes a cover illustration interesting and if the interest in itself is individually considered or if there are certain general rules regardless of the observer.To reach a conclusion I have been studying components in advertising pictures, visual communication and how the commercial producers use advertising to communicate with the observer. Semiotics, advertising and comparisons between the cover illustrations have been my method for analyze.I have come to the conclusion that cover illustrations are meticulously produced, and that every single part of them is important for the observers? over all impression and interpretation of the cover illustration.

This thesis is an attempt to study whether if problem-oriented teaching implies a moreadvanced use of school libraries than other teaching methods.Teachers have been interviewed about what kind of information they and their pupils need,and where they find their information. Another question is whether the problem-orientedteaching method makes it easier for the pupils to find information in school libraries thanother teaching methods do.The result of the study is that a problem-oriented teaching method creates opportunitiesfor the school library to become an important place for information retrieval. This teachingmethod is a major, but not the only determinal factor. Other contributing factors could beteamwork between teachers and school librarians and the existence of learning aids..

Adaptivt kamouflage är en signaturanpassningsteknik som ger stridsfordon förmågan att anpassa sin värmesignatur utefter omgivningen eller imitera andra objekts signatur, i syfte att undgå upptäckt eller identifiering.I denna studie genomförs en analys om vilka folkrättsliga problem som kan uppstå vid användandet av adaptivt kamouflage.Studiens resultat visar att de folkrättsliga problem som kan uppstå vid användningen av adaptivt kamouflage är distinktionsproblem, då tekniken möjliggör för stridsfordon att imitera signaturen av civila personbilar. Denna användning av adaptivt kamouflage kan anses som brott mot distinktionsprincipen..

Triage, which means "to sort", determine the priority of the patients need of care. The aim of the present study was to describe nurses? perception of triage at a pediatric emergency department. A questionnaire with open- and closed-ended questions were distributed to all 25 nurses that worked at a pediatric emergency department. The answer frequency was 48 % (n=12).

The aim of this masters thesis is to investigate how childrens librarians deal with gender issues in their work when acquiring and mediating books to children, and how reviews in Bibliotekstjänsts Sambindning can be of help in this aspect. The thesis focuses on children between 6 and 12 years of age and their reading of fiction. Four interviews with childrens librarians and an examination of reviews in Sambindningen have been carried out. The reviews were examined both by finding out with what frequency gender issues are dealt with and by studying 20 childrens books from a gender perspective, comparing my judgement with the one they got in the reviews. The examination of Sambindningen showed that the reviews therein only sporadically bring up gender issues.
