The free movement of the Roma minority has become questioned within the European Union. This study seeks to understand why this question has reached disproportionally importance in comparison to the number of Roma migrants within the union, and to understand the great attention given to the question. Based on the Copenhagen?s school of securitization, the purpose of this study is to show how this magnification of the question occurs due to the framing of the Roma migrants as a security problem. Focusing on the speech act of the securitization theory, this paper contains a study of political actor?s statements concerning Roma migrants.

The idea with this study is to examine if there are a connection between how optimistic people are in relation to how stressed they feel. The result from the survey is based on materials from a questionnaire has been sent to fifty persons of varying age and sexes. The questionnaire has also been sent to students from Karlstad University but also to friends and acquaintances. The data is measured with SE- and LOT-tests. The issues concerned in which scope respondents experiences themselves stressed and optimistic and how the connection is between experienced stress and optimism in relation to results on the figure tests.

This Master Thesis has been conducted as an assignment of the Swedish Defence MaterialAdministration and the Swedish Armed Forces and aims to examine the Target Location Error(TLE) of a Forward Observer System. The targeting accuracy of the system is vital if the systemis to be used as a sensor for precision munitions. The analyzed system, EOI (FOI 2000), wasdelivered to the Swedish Armed Forces in 2007. The targeting sequence starts with deciding theposition of the system with a GPS-receiver, continues with methods where the north direction issettled and ends by measuring the distance, direction and elevation to the target. When allparameters have been measured the system calculates the position of the target.

The views on and the knowledge of the introduction of iron to Scandinavia have change by the history of archaeology. The results and discussions are put in the context of time and how that time is reflected in their work and texts. This limits that scholars put up to orientate themselves conceal the complex reality. The limits are changing all the time and is dependent of time and person..

 This paper is about the conflict between the Middle East and the Western world after the Danish newspapers? cartoon publications of the prophet Muhammed in October 2005. The conflict resulted in massive reactions in the Middle East and the Danish-Swedish dairy company Arla Foods, was boycotted during six months in 2006. The aim of this study is to describe how the biggest Swedish daily newspaper,Dagens Nyheter and three Saudiarabic newspapers Al-Hayat, Al-Watan and Shark Al-Awsat described "the Other" during the crisis in the year of 2006. Another aim is to describe how Arla Foods managed the consumer boycott.

The project was made in cooperation with Coffee Queen AB, Arvika. The task was to develop and design a new cooler for the milk to Jura Impressa X9, an espresso machine. The good assistance with staff at Coffee Queen and engineers in China and at KPA in Karlstad led to a solution to the problem. It was a long road to get there, many different concepts was developed. When the day came to decide which concept to work with, the choice stood between two different technical solutions.

This master thesis was a subtask of a project called EMIR-1. The goal with the thesis was tobuild a system for particulate mass measurements in one of the engine test cells at KTH. Theparticulate mass measurements are planned to be measured with a TEOM.The exhaust gases must first be diluted with air before the sample is sent to the TEOM.Therefore an ejector diluter for this matter also was designed and evaluated in the thesis.Emissions measurements have been done both with and without dilution to determine thedilution ratio. Tests have been done for different speeds and loads.Problems with stability of the dilution ratio have been an issue throughout the process andpressure pulsations in the exhaust pipe are believed to be the cause. More tests have to be done tomake sure that this is the problem.One idea is to make the inner diameter of the diluter nozzle smaller and see if it changes thedilution ratio stability.

The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.

The work describes the development of an adjustment algorithm that will replace today?s manual adjustment of Lead- and Lag-filters at ABB Robotics industrial robots. The adjustment is mainly for the filter parameters in the control system.Three different algorithms have been created to replace the manual adjustment. One of them is based on the criterion from the manual adjustment and another one on optimization of the sensitivity function. The last one is a combination of the two.The report describe the development of the algorithms and how they behave during simulations and tests on real robots.

Glulam is a product that was engineered to make use of timber in a more efficient way. Bychoosing timber of similar quality and discarding natural defects during production, thedevelopment of a stronger cross-section is achieved.Carbon fiber is a relatively new material with a high tension capacity. This feature is used toexamine how the bending capacity of the beams improve by adhering carbon fiber laminateson the lower edge of the beamsThe strength of the material is tested with three experiments: carbon fiber on the bottom of thebeam (a), carbon fiber attached to the lower sides of the beam (b) and carbon fiber in thebeam, covered with a layer of wood (c)The results show that the first case, where the carbon fiber is attached to the bottom of thebeam, gave the best result with an increase in capacity of 59 % compared to the nonreinforcedcontrol. The other two cases also show an improvement in capacity, beam-type 3had a capacity increase of 47% and beam-type 4 increased with 25 %Tests were also made with glulam beams reinforced with fiberglass, but these tests were notanalyzed in depth because the purpose was to compare the capacity to carbon fiber. Thisbeam improved its capacity by 40.3%.The tests show that carbon fiber as a reinforcement material for glulam is a good choice whenthere is a requirement for stronger cross-sections in both new production and renovation ofold buildings.

This study highlights the differences in articulation, nasality and intelligibility between twenty 16-year-olds and thirteen 19-year-olds born with isolated cleft palate and control groups. The test groups are compared in a longitudinal perspective and based on earlier evaluations of velopharyngeal impairment. Significant differences were found between test groups and control groups using quantitative comparisons based on SVenskt Artikulations- och Nasalitets-TEst and NasometerTM. The longitudinal comparison also showed a positive but not significant development of the speech. Differences emerged in the comparisons based on velopharyngeal impairment but no significance analysis was made.

The Swedish state and educational system are secular, so to say they do not depend on the former protestant state church anymore. Many people in Sweden are also secular. Even so, in school teachers meet students with a religious faith. The purpose of this study is to examine how teachers without a religious belonging experience the encounter with religious students. The method used was semistructured interviews with five teachers in a upper secondary school in a multicultural suburb of Stockholm.

We set out to compare two different categories of workers: the, so called, white- and blue collar workers. The studies aim was to measure if there were any observable differences between the two in means of optimism and sense of coherence. There are two tools created for measuring optimism and sense of coherence, the Life Orientation Test ? Revised (LOT-R) measures an individual?s level of optimism and Aaron Antonovsky devised a test for measuring an individual?s level of sense of coherence (SOC). Optimism is best explained like a way to measure anticipation, how an individual expect future events to fall out.

The essential thing about breaks has been in relation to time, body, movement, force and room during my examination. Through conversations high-school students from two schools have taken part in this study. The examination is based on conversations with the students and has focused on students? experiences of breaks, and is also carried through by the method of phenomenology. The results of my studie show that students - during their breaks - experience a feeling of allways heading for something and also that time seem to exist in three levels: filled time, non-filled time and flow regarding of time.

One purpose of our study was to investigate if equality in work time and parental leave in a relationship affect the time that parents spend with their children. Our first hypothesis was that increased equality in work time and parental leave leads to a reduction of the parents? total time with their children, ie the children spend more hours in pre-school and begin pre-school earlier. In order to test our hypothesis, we investigated the relationship between the woman?s and the man?s work time and parental leave and the time that the children spend in pre-school as well as at what age they began pre-school by using two surveys.Our study showed a significant coherence between both working women?s work time and the children?s time in pre-school as well as women?s parental leave and the children?s age at start in pre-school.
