This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.

The Swedish school reflects the society that we have today, a society with many different ethnical and cultural backgrounds. The purpose of this investigation is to study how the school is working with children that recently immigrated to Sweden. What kind of methods are they using at school, to get the best development as possible? Do the teachers manage to be concerned of the students in the school? What kind of reception do these children get in the school? What methods are the teachers using? And are these methods really the best to use to enhance the language and cognitive development of these students?The methods I have been using to examine these questions have been qualitative. I have interviewed three teachers about their everyday work in a multiethnic school south of Stockholm.

The first part of the thesis consists of a brief introduction to the general principles of target detection and the sensor-systems used. In the following part there is a theoretical description of the algorithms this thesis focuses on. The detection algorithms described in this paper are called Cell Average, Ordered Statistics, 2parameter and Gammadetector. Two different discriminators called Extended Fractal Features and Quadratic Gamma Discriminator are also described. The algorithms are tested on three different types of data, simulated SAR-pictures, authentic SAR-targets and IR-pictures.

A thesis directed towards Innovationsslussen in Gothenburg about securing, improving and simplifying sitting on the toilet for patients with sitting difficulties. The primary target group for the project is patients who have had a stroke and as a consequence from that suffers from various kind of bodily paralysis.An overall goal was to design an aid that was comprehensive enough that the patient could manage sitting securely on the toilet without have a nurse giving physical support during defecation.Five conceptual proposals were developed and evaluated in consultation with Innovationsslussen and one was selected to be further developed.The result was an integrated support at the toilet that facilitates a good sitting posture which minimizes the risk of falling and provides comfortable support when leaning to the side. The product is divided in two with both a redesigned carryingsystem and a new type of support surface adapted for the purpose..

This exam work project strives to investigate different roles a teacher can adapt to in classroom situations. The focus is on three different types, gained from a dissertation made by Evelyn Säll where she has investigated teacher students? opinions about the teacher?s role. These types are:the Dramatist, the Director and the Illuminator, and five teachers are defined accordingly. Questionnaires and observations are used as a tool in order to come to a conclusion.

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.

The use of out-door pedagogy in the school has been frequently high-lighted during recent years. To which extent out-door education was practised in the school depends on the opinions among the active teachers. The aim of this study was to examine the opinions on out-door pedagogy among teachers in classes 4-6 of the elementary school and to find out to which extent the teacher used out-door teaching. The study was based on qualitatively structured interviews with 4 teachers having different lenght of teaching experience. The results of the interviews showed that the teachers had different opinions on the definition of out-door pedagogy.

This paper is based upon a questionnaire and interviews with Swedish secondary school teachers (student of ages from 16 to 18). The purpose of the paper was to get a picture of teacher?s attitudes to astronomy in the physics courses and how this affects their teaching. The questionnaire showed that astronomy is the least prioritized field in physics in secondary school. Teachers seem to generally consider astronomy as the least important field and they spend little time teaching it, many teachers even exclude astronomy completely from their classes.

The aim of this essay is to study five teachers' perceptions and experiences of a multicultural class. I want to find out how they relate to intercultural education and how they experience that they may apply it.Sweden is a multicultural society. This fact is even reflected in the school and this imposes on teachers finding new ways to educate and prepare their students for the multicultural society.I chose to carry out a qualitative survey and interviewed five teachers having contact with a multicultural class. The study also offers suggestions to future teachers who can benefit from it in terms of adopting convenient attitudes in multicultural classes with better understanding.The outcome reached shows that the interviewed teachers try to make use of intercultural pedagogy by addressing differences between students, adapting teaching to supply for the needs of students, and also by having good contact with parents. But teachers also experience difficulties.

In 1911 Valfrid Palmgren founded the Children's Library of Stockholm, the very first in Sweden.She was a well-educated woman, who believed in social and educational equality for all.During a journey to the USA in 1907, she was deeply impressed by the public libraries, andshe put many of the public library ideas to use in the Children's Library of Stockholm. Palmgrenstrongly opposed to the Swedish libraries not allowing admission to children, since shefirmly believed that educating the people had to start with the children.Other reasons for opening a children's library were to give children an alternative to roamingthe streets, to give children a quiet place to read, to give an alternative to the cheap trashliterature that flooded the market and to teach the young ones how to extract information frombooks. Of great importance was that the library should be equal to all classes in society.In 1927 the children's library was taken over by the new public library of Stockholm..

This is a study of the national test in 3rd grade. The national test is obligatory and is conducted in 5th and 9th grade, but since the spring of 2009 the tests also become mandatory in 3rd grade. The case study of this research is to find out how children in 3rd grade perceive the purpose of the national test. The survey should also clarify how students think and feel about the national test, and how they feel before the national test and after they have finished writing the test. Has the test positive or negative influence on children? The survey will also show how much teachers clarify what the significance of the national test is for the students.

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The aim of the work was to compare fuel consumption during work in practical field conditions with a standardized method developed by Skogforsk (The Forestry Research Institute of Sweden), (Brunberg, 2005) for harvesters and forwarders from different manufacturers and of different sizes in order to promote the development of more fuel efficient machines. Two studies were carried out. - Statistics of fuel consumption were collected. - An inquiry was sent out in order to get more detailed information of different aspects influencing the fuel consumption. The studied machines were divided into two classes, large machines (> 150 kW), and average size machines (100 ? 150 kW), and of the manufacturer Timberjack and Valmet. Our results shows a 15 % lower fuel consumption for average size harvesters and an 8 % higher fuel consumption for large harvesters compared with Skogforsks model.

The aim of the study was to compare how the population of pine (Pinus sylvestris) and spruce (Picea abies) have changed between 1927 and 2013 in the oak landscape south of Linköping. A field study was carried out in 22 two kilometre lines which also had been studied in 1927. In these lines, which where ten meters broad and had a direction from west to east, the pines and spruces were counted, measured and classified by steam diameter. The obtained result was that the basal steam area (m²/ha) had increased for pine (44%) and spruce (57%) between 1927 and 2013. The amount of trees had increased in all diameter classes except thinner pine and spruce with a diameter of 5-10cm.

The aim of this study was to describe how girls and boys have been represented in the Swedish children?s? magazine Kamratposten from 1950 until 2010. Kamratposten was chosen because it has both boys and girls as target audience. Three articles about children from the years 1950, 1960, 1970, 1980, 1990, 2000 and 2010 were chosen as material of the study.The study is a discourse analysis that deconstruct the gender discourse of Kamratposten. The analysis is done with a gender perspective.

Consumers seem to become more demanding in their buying behaviour within the fashionmarket. The society refers to individualism, personality and creativity, which affect people?s wayof dressing themselves. Many companies have started to work with aspects that create aconsumer experience to meet the customers? new demands.
