This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.

The purpose of this essay is to analyze three works that are regarded as fictional biographies. In all three selected works the protagonists are historical Swedish women who are known for being a part of the cultural sphere of their time. Two of them are also recognized as important and somewhat pivotal characters in the struggle for women?s rights at the turn of the 19th century. The analyzed works, however, accentuate the women?s private life.

In this essay we strive to examine how the social work in Sweden will be affected if the Swedish welfare model goes through fundamental changes. The study illuminates the close connection between the Swedish collective bargaining model and the Swedish welfare system. The questions we present in this essay, and hopefully answer satisfactory, are: is the Swedish welfare model subject to thorough changes? How will such a change alter the social work in Sweden?, is the Swedish collective bargaining model in a state of modification? Would a modification in the collective bargaining model have effects on the Swedish welfare model?We have used a qualitative method in collecting empirical material. We interviewed three representatives, who worked for Confederation of Swedish Enterprise, IF Metall and The Swedish Municipal Workers respectively.

In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.

AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

This essay examines the international communitys intervention in Bosnia. The purpuse i to give the reader a deaper understanding of the problems appeared in re-building the bosnianstate. Office of the higher representive (OHR), was to become the koordinator of therecontruction of the institutions and governance. The theory used fore the examination isstate-building, whith an alingnment of state-building trough the international community.The second part of the essay examine the ideas of the High representive (HR) trough threedifferent dimensions. The idea-analysies search to present the core of ideas of OHR, nationalparties and the reconstuction of media.

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

This degree project is on 15 university points which correspond to 10 weeks full time studies. The work has been carried out during autumn term 2007 and spring term 2008. This degree project has been carried out with the cooperation of Etac Supply Center AB who is located in Anderstorp.It?s been Etac interest to develop a solution which helps the user of the wheelchair over obstacles. My task has been to develop a concept that solves the problem according to the requirement specification.In the rapport the reader can follow the development from an idea to a finished concept.

Background: In 1998 it was stated that Swedish municipalities would report the pension liabilities according to the mixed model where the pension liabilities before 1998 was moved from the balance sheet. The mixed model has been criticized by economists for not showing the total pension liabilities. To remove some of the liabilities in the municipalities balance sheets means that the solvency improves. Some municipalities have decided to go against the municipal accounting law and recognize all of the pension liability as a liability according to the full funding model. When two accounting models are being used the comparison of the municipalities' financial statements is much harder.Purpose: The main purpose of this study was to study the reason why some municipalities apply full funding model rather than the mixed model.

The aim of this two years master?s thesis in library and information science is to study how children and librarians recommend books through the website Barnens bibliotek. In the scope of this aim it also tries to answer the following questions: What qualities in books do children and librarians respectively emphasize when they write book recommendations? How do they formulate the recommendations? And finally, how do their respective recommendations differ?To examine these aspects a total of 50 book recommendations were chosen and analysed through an hermeneutic approach. Out of these 50, 30 were written by children and 20 were written by librarians.

The aim of this study is to analyze how two different education books produce christianity and islam. The analyzed books is from 2003 and 2008 and the books are adapted for the last years of primary school. The meaning and translation of words is often a problem and can get the reader wrong understaning of the religion. The analyze include the perspective of this meaning and how the sacred things are described in each religion.The textanalyze is made with different criterias; the context, the pre- understanding and if the text is objectiv is some of the most important. The language is important too.

The purpose of our essay is to examine if variation exists in the way that auditors try their independence, this so called analysis-model. We will suggest some factors that influence the way auditors practise the analysis-model. The institutional theory predicts no differencies since the normative pressure could be expected to be severe. But we found that among other things people?s qualifications, personalities and audit firm?s size and age influence the way auditors try their independence.

In this essay, I analyze the syllabus for Swedish with specific regard to literature teaching. I identify three different perspectives which carries seperate implications. First, a text-centered perspective, which tends to position the importance of the text as a part of a tradition. However, this seems to distance the reading from the reader, and place the importance of the reading event outside the student. The consequence might be that the student employs an instrumental reading which simply responds to a pre-set idea of meaning.

A new material model, for the FE-program ADINA, has been verified against twoexperiments. One unreinforced concrete beam and one reinforced concrete beam.The model, DF-concrete, has the possibility to estimate true concrete. However theresults indicate that in order to be sure that the estimations are true, there ought tobe data from the true concrete to verify against.Two FE-models have simulated the behavior of a ring-shaped part of the nuclearcontainment vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the nuclear containment vessel show cracking in the concrete after10-11 bars of over pressurization.
