Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.

When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.

Bakgrund: Fibromyalgi karakteriseras som ett kroniskt sm?rtsyndrom pr?glat av omfattande sm?rta, tr?tthet och s?mnproblem, vilket avsev?rt f?rs?mrar den drabbades livskvalit?. Syndromet, som drabbar tv? till fyra procent av befolkningen med en ?verrepresentation av kvinnor, kr?ver en multidisciplin?r behandlingsstrategi p? grund av dess komplexa natur. Diagnostiseringen av fibromyalgi utg?r en klinisk utmaning, givet avsaknaden av objektiva biomark?rer, och bygger ist?llet p? patientrapporterad sm?rta som kr?ver att patienten uppvisar sm?rta vid palpation p? minst elva av arton definierade ?mma punkter (tender points). Syfte: Syftet ?r att unders?ka patienters erfarenheter av att leva med fibromyalgi. Metod: En litteratur?versikt med en systematisk ansats utf?rdes genom att analysera data insamlade fr?n databaserna CINAHL, PubMed och Scopus. Det resulterade i nio relevanta artiklar, varav ?tta var kvalitativa och en kvantitativ, publicerade mellan ?ren 2012 och 2024. Resultat: Det identifierades tre huvudteman och sex underliggande subteman.

This thesis concerns the Gotlandic hill-forts (sw. fornborg) situated on a cliff or in an elevated position and which traditionally have been referred to as cliff-forts (sw. klintborg/höjdborg). The study derives from the notion that these monuments, diverse in size and shape, by archaeologists have been viewed and treated as a homogeneous category of ancient remains. The author?s key aim is to challenge this perception by identifying various subcategories from the 28 cliff-forts on the island.Ever since the archaeological discipline initiated the study of cliff-forts in the late 1800s and more or less to present day, the interpretations have been almost solely dominated by explanations of the military and defendable nature of them.

Sustainability reports have during the last decade had a strong development. Both in terms of establishing a sustainability assurance, in its form, and get it assured together with standards, principles and regulations which organisations and accountants have utilized. The growth of sustainability reports and the choice of getting them assured have in particular favoured the accounting business. Due to this result, some critics have voiced that assuring a sustainability report gain accounting firms more than it gains the actual organisation. Other say that it is necessary in order to increase the credibility and the eligibility of the report, while it also has become a requirement from stakeholders.

Brottsligheten i Sverige har ökat. Två av fem individer återfaller i brott efter frigivning. De individer som lever i utanförskap och kriminalitet är i en utsatt position. Flertalet av kriminalvårdens klienter har behov av insatser från olika verksamheter för att klara sig från återfall i kriminalitet. Syftet med studien är att få en djupare förståelse om vad före detta kriminella anser har varit betydelsefullt i deras process att lämna sin kriminella livsstil.

REINERTSEN AS performs expansion and buckling analyses of pipelines using ANSYS, afinite element modelling and analysis tool. In an expansion analysis the pipeline is modelledwith thin?walled pipe elements called PIPE20 which allows plastic deformation. However, ina recent analysis the results retrieved from the PIPE20 element were incorrect for strainsabout 1 percent. One main issue was that the PIPE20 element overestimated the strains.The purpose with this Master Thesis was to become familiar with the theories and analysismethods used in pipeline design.

Because of an increasing demand from customers and changing external environment, there is a need for continuous improvements, for both manufacturing and service organizations, to meet these demands. Manufacturing organizations have been working systematically with quality improvements for a long time, but it has not been as common for service organizations. Because of that the methods to use for implementation of the systematic improvements have not been designed to fit service organizations, and not either for public organizations. The purpose of this thesis is to explain if and why the Swedish Road Administration?s organizational culture and handling of ideas and deviation support an implementation of continuous improvement management.

In this two-years masters thesis the information practices of former interns are examined in relation to a possible lack of certain kinds of information in the prison environment. The essay is positioned in the research field of information practices which means its looking at all kinds of information, formal and informal. Since the essay is in the field of information practices it means the focus lies in how information is taught whithin contexts and groups. Information is not looked at solely as an individual process but is seen as a collective experience.The method of the essay is that of the qualitative research interview. Besides taking an interest in information practices i investigate whether access of information in prisons could be improved and whether the library organisations could be a part of those improvements.The result of my research shows that information in the prison coming from the correctional institution is not perceived as well functioning.

The purpose of this thesis work is to create a prototype for an augmented reality application that isaimed to support service technician when performing service and maintenance of machines andengines. The prototype will be used for investigating what technical limitations there is and toestablish basic usability for the user interface. The method that is used is user studies and analysis toevaluate use cases and user stories. An iterative work process is then applied for design and theprototype is continuously user tested.The resulting prototype uses a Samsung Galaxy Tab 2 running on Android operating system. Theframework used for augmented reality is NyARToolkit which handles marker recognition andconnections to Android.

Abstract:Styrdokument i musikämnet-En komparativ studie av norska och svenska styrdokument i Musikämnet i skolan.(Music Subject governing documents- A comparative study of Norwegian and Swedish policy documents in the Music subject in school)The purpose of this study is to compare the Norwegian and Swedish policy documents on teaching in the Music topic. The comparison also applies to the requirements which have been in Sweden over time. In comparison, the policy document LGR 11 from Sweden, analyzed, and the governing documents MUS1-01 and R94 from the Norwegian School.The main issue in the study is: How does the policy documents for the topic music in Sweden, compared to Norway? In order to answer the question, I compared the above-mentioned policy documents and set in relation to the musical substance is designed in Norway and Sweden.In curriculum theory treats one problem based approaches in structural functionalism, pragmatism, social epistemology and post structuralism. The starting points are then used to explore various relationships between curriculum theory and didactics.The principal researcher and proponent of curriculum theory is Ulf Lundgren.

Swedish agriculture stands in front of big changes the whole time. As a milking producer you have to adapt and develop the company to these changes and find the best solution. This potential is easy to find if you compare your company with other similar companies. Labour cost is the biggest cost in milking production after the cost for food. Today it is rather easy to measure how many hours per cow different system of cow houses needs, but we do not know so much about how many hours it takes to breed a calf. To learn more about the labour time with the calves during the first time after the calf was born, I made time studies on five different farms with calf hutches, automatic milk system, large calf boxes, and smaller calf boxes with teat buckets.

Vilka diskurser ger elever och lärare uttryck för i pianoundervisning? Syftet med min uppsats är att undersöka hur pianoelever och pianolärare på kulturskolan och inom ett studieförbund genom språket ger uttryck för en mängd förhållningssätt och attityder. Vad sägs i samtalen kring deras undervisning och vilka diskurser och tankekollektiv bildar dessa åsikter tillsammans? Jag har använt mig av fyra djupgående intervjuer och två videodokumentationer för att dels studera elevernas och lärarnas uttryckta upplevelser men också för att ta del av det som verkligen sker under lektionstid. Teoretiska utgångspunkter har utgjorts av kritisk diskursanalys, institutionsbegreppet och interaktionsteori.
