Volatilitetsprognoser på den svenska aktiemarknaden: Tillämpning av Arch Typ modeller
This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.
"Det är svårt det där med sanning? : En studie av text/bildrelationen i Sven Nordqvists verk När Findus var liten och försvann & Var är min syster?
The aim of the study is to investigate the relationship between text and picture in two works by Sven Nordqvist, with the focus on how the action is propelled. The two works are compared in order to bring out any differences in the relationship and what significance this can have for the interpretation. The study also considers the theory of conceptual worlds to examine how the books can promote pupils? literary understanding. The method of analysis is based on Rhedin?s (2001) theoretical concepts and elements of Nikolajeva?s (2000) terminology.
Sambandet mellan intima media tjockleken och body mass index.
Vid mätning av HbA1c i blod visas medelkoncentrationen av glukos som en person har haft under de senaste tre månaderna och analysen används vid uppföljning av patienter med diabetes mellitus. DCA VantageTM är ett patientnära analysinstrument som utvecklats för att kunna utföra laboratorieanalyser inom till exempel primärvården. Patientnära analysinstrument är viktiga för att minska tiden från provtagning till behandling. DCA VantageTM är ett halvautomatiskt analyssystem som utformats för kvantitativa mätningar av HbA1c i blod. Syftet med studien var att utföra en verifiering för att se om DCA VantageTM (immunoturbimetrisk metod) kunde användas som ett komplementinstrument till VariantTM II Turbo (high performance liquid chromatography, HPLC).
Utveckling av en HBV/PULS-model med sammanfogade markfuktighets- och responsrutiner
Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.
Den kontrollerade tekniken : En studie om de exklusiva Plymouthbrödernas förhållande till samtida teknik
The purpose of this thesis is to examine the Swedish Plymouth brethren?s relation to contemporary technology. What types of technology are considered acceptable and where do they draw the line? Due to the brethren?s separation from the parts of the world they believe leads people away from God, such as the entertainment industry, immoralities etc., they reject use of television and radio. These two are viewed as uncontrolled types of technology since the user does not have control of its contents.
Kommunikation som berör - En observationsstudie om sjuksköterskans kommunikation med närstående inne på patientrummet på IVA
Patients in intensive care are often intubated, and therefore unable to speak, which leads to difficulties in communication. The ICU is a very stressful environment and can be experienced as foreign and frightening by both patients and their close ones. The ICU nurse?s caring responsibilities includes both the care of the critically ill patient and the support of relatives who are often in shock. This balance is not always straightforward, and acting professionally in both instances can lead to problems.
Kapitalstruktur i banker, en jämförelse mellan Storbritannien, Sverige och USA
Background and problem: The importance of banks was clearly shown during the last financial crises, when the crises that started in the banking sector spread to the rest of the world. This is one of the reasons that this thesis is focused on banks in particular, one other reason is that a lot of previous studies has chosen to exclude banks because of the fact that their balance sheet differ from non-financial companies. This thesis is a beginning in filling in the gap that exists in the knowledge of banks capital structure. Purpose: The purpose of this thesis is to prove that it is possible to explain the capital structure in banks and that differences in the capital structure of the banks in Great Britain, Sweden and the United states of America exists. Method: The fact that our study is partly a replication of two earlier studies made a deductive approach most appropriate.

Brasslärares tankar om, och inställning till, att undervisa på olika instrument
This study is based on discussions among Swedish brass teachers about teaching other brass instruments than their main instrument. Why do some choose to teach only with the help of their main instrument while others use their secondary instruments as well? What are the advantages and disadvantages and how do they look upon other ways of thinking in this matter?In addition, the study examines brass teachers? views on the balance between pedagogical and instrumental skill, as well as their views on teaching sound, technique and expression in relation to the age of the student.A questionnaire was used and anwered by 24 teachers with teaching experience in municipal music schools ranging from 7 months to 35 years. The results indicate that pedagogical skill is always important, whereas the importance of instrumental skill increases as the student gets older and more experienced. The advantage of teaching with the help of the main instrument is that one always keeps a high musical and technical level.
När ett vallöfte blir verklighet : Analys av DN:s rapportering om fastighetsskatten innan och efter valet 2006
Did the mass media report in a different way about the real estate tax before the Swedish national election 2006 than they did after the election? If there were differences, what could be the cause?This study aims to answer these questions by using a quantitative analysis of articles about the real estate tax published in the Dagens Nyheter (DN), the biggest morning daily. The summer before the election, the ?Alliance?, (the non-socialist coalition, launched an election promise to abolish the real estate tax. Instead they planned to introduce a low community charge.The Alliance won the election and formed a government to implement their election promise. The analysis was made on all the published articles in DN that covered the real estate tax issue. In total there were 43 such articles. These where all published between the launch of the campaign promise until the electionday and a month before the proposal was launched 19/9 2007, until the proposal was implemented in 2008. The study results in three interesting conclusions.
Genus på menyn : Analyser av stabila kol- och kväveisotoper på skelettmaterial från Bjärbygravfältet från äldre romersk järnålder i Kastlösa på Öland
This paper deals with diet and gender in the early roman iron age in Sweden. Human bone and tooth material from the Iron Age cemetery at Bjärby in Kastlösa parish on the island of Öland have been analysed for stable carbon and nitrogen isotopes. 21 individuals were sampled. Where possible 4 samples were taken from each individual, from the first, second and third molar respectively and from one compact bone. By doing so it is possible, at least in theory, to trace intra-individual diets throughout life.
Uppskattning av Ytkurvatur och CFD-simuleringar i Mänskliga Bukaortor
By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.
På väg mot ett mer hälsosamt samhälle? : En kvalitativ studie över hur kvinnor mellan 17-65 år blir påverkade av massmedias hälsorapportering
Bakgrund: Vi lever idag i ett informationssamhälle där vi ständigt matas med ny kunskap och olika valmöjligheter. Ett område som har fått ökad plats på massmedias agenda på senare tid är hälsa och livsstil och dagligen exponeras vi människor av budskap över hur vi kan förbättra vår hälsa och ändra våra levnadsvanor.Syfte: Syftet med vår studie var att undersöka om en utvald grupp kvinnor mellan 17-65 år blir påverkade av massmedias hälsorapportering och de hälsobudskap de möter. Vi syftade även till att undersöka hur denna eventuella påverkan yttrar sig samt klargöra vilka eventuella skillnader det finns i påverkan mellan olika åldrar.Metod: För att få svar på våra frågor genomförde vi en kvalitativ studie med samtalsintervjuer som datainsamlingsmetod. Vi intervjuade 6 kvinnor i åldern 17-65 för att ta reda på deras upplevelser och tankar kring problemområdet.Slutsats: Resultatet av undersökningen visade att vår utvalda grupp kvinnor blir påverkade av massmedias hälsorapportering. Resultatet visade även att åldern har betydelse när det gäller hur och i vilken grad respondenterna blir påverkade av hälsobudskapen.
Representation av aktiva regler i ett systemvetenskapligt perspektiv
En aktiv databas reagerar automatiskt på händelser som genereras internt eller externt i databasen. Det aktiva beteendet i ett databassystem kan ses som övervaknings-funktioner för databasen. Det innebär att kritiska system som stridsledning, sjukvård och kärnkraftverk har stor förtjänst i att använda aktiva databaser. En passiv databas, vilket är det vanligaste idag använder sig av polling och embedded code för att åstadkomma aktiviteter som finns i den aktiva databasen. Dessa lösningar genererar dock redundans, överbelastning av systemet och tidvis inkorrekt information.Vid ett systemutvecklingsarbete används oftast en eller ett antal bestämda metoder som tillför riktlinjer och tekniker till utförandet av arbetet.
Födoämnesallergi : Föräldar och barns upplevelse av förskolans bemötande
In this essay I have investigated how two families, with children, who have food allergies, experience what support and what treatment they get in preschool for their difficulties. I have interviewed two children and two parents. The study shows that the interviewed parents believe that more knowledge in the community and among staff in preschool, about food allergies, is needed. Parents wish that the staff should write an action plan that describes how to deal with children who have food allergies and that preschool invites parents and children to record results. It is important to consider an inclusive attitude so that children don?t feels excluded.There is some research going on around this subject and researchers agree that the incidence of food allergies in the society is growing, but that it is difficult to be able to present a certain theory why, and what the underlying factors are.
