Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

The purpose of this study is to examine what factors that motivate people to work in professions with an explicit and inherent risk of threats and violence. By using a qualitative study and conducting in-depth interviews with eight security guards and doormen with experience from working at restaurants and nightclubs, the study could conclude that the interviewed security guards and doormen were motivated mainly by economic incentives and the social interaction that the profession entails. Status and riskiness of the profession did also, to a certain extent, contribute to the motivation. The professions' lack of advancement opportunities were frequently mentioned as the main reason to why one chose to leave the position, or consider the time in the profession as limited..

Background: Triage is the sorting of patients according to the severity of medical assessment. Triage has a long history of use in Anglo-Saxon countries but is a fairly new method in Sweden. Researchers have described the Manchester triage group method (MTS) and a literature review of the concept; working contentment and competence focusing on triage. Aim: The ambition with this study was to describe a number of triage nurses working conditions. The research questions were; working with MTS- does it bring work contentment? What kind of competence is needed? Method: Data was collected from 74 triage nurses by a questionnaire containing 37 questions and two questions provided the nurses the opportunities to describe their triage experiences.

This essay is reading the Swedish author Stig Larssons debut Autisterna [The Autists] (1979) in the light of Gérard Genettes narratology and the time philosophy of Gilles Deleuze. The focus of the essay is time and how it is seemingly dissolved. The essay maps out a chronology of the non-chronological novel and from there discusses the breaking up of the empirical time. The essay uses Deleuze to explore the time-image of the novel to see how it is built up in the text for example by literary anyspace-whatevers. Hence the title, Anytime-whatever.

The aim of this essay is to examine how students in 6-9 grade with reading and writing difficulties are treated and supported by teachers and staff at Ideskolan, a community school north of Stockholm. I have chosen to answer the following question:- How does Ideskolan cope with and support students with reading and writing difficultiesThis has in turn generated the following questions:- How is special education organized at Ideskolan?- Is a diagnose always needed in order to deploy extra support?The method I have employed is observation while participating, together with informal talks and interviews. I have visited Ideskolan twice, one week at the time. The material that the visits have generated is the foundation of the essay, supported by previous research in the field.The essay clarifies what right to special support students have according to law, regulations, curriculum and teaching plans and what they look like in reality at Ideskolan.

Swedens membership in the European Union have resulted in an international characterized labour market. The construction sector is the area who employs most posted workers among the 7400 employees who monthly enters the market. It?s also the sector where a big part of the work-related deaths occurs. The purpose of this study is therefore to contribute to a greater understanding of the regulation regarding posted workers, their work environment and the consequences of it.

Water connects heaven and earth. Water is the most obvious element of nature. To move in water is for me more than cooling of on a hot summer?s day. It is about freedom and the feeling of being above the state of things.

AbstractThis degree project is about having meetings in The Swedish Social Insurance Agency, which is awide organisation. This work will concentrate on one of the projects going on within theorganisation which is travel-free meetings, where they are building a video meeting system thatallows the employees in the organisation to be able to meet with each other through the use ofvideoconferencing instead of physical meetings.In this work we will show how Kaikaku (radical system changes) along with Kaizen (continuouschange) can support an organisation to become more efficient and reduce wastage. We have donethis work in an organisation that is present in over one hundred locations in Sweden.The Social Insurance Agency has over 13 000 employees at over one hundred locations inSweden.The organisation has to be close to their customers and provide the best service aspossible. To be able to work in a uniform way, the employees get together and have meetings.Some meetings are just progress meetings and takes perhaps no more than two hours to complete.However, if seven employees from seven different locations need to have meetings, in the worstcase, they all have to meet in a common place.This is expensive for the organisation in travel costs, time and absence from work, but thetravelling also contributes to environmental pollution if the employees are travelling by a fuelpoweredvehicle.A whole day could go lost for having a meeting in about two hours if all sevenemployees went from their own cities to e.g. Stockholm for the meeting.Muda (wastage) of travel created several different types of Muda, namely:? Wastage with anticipation when the employees had to wait for e.g.

The purpose of this work is to explore and illuminate the circle times function and importance of preschool by the pedagogue perspective and the circle time design in relation to children's age group composition. The study questions are:What is the purpose of circle time in preschool educational activities according to the teacher and how does the teacher look at his own role?How do the teachers plan, design and perform the circle time of small children and big children's section? What similarities and differences exist?This is a qualitative study based on interviews with four preschool teachers and observations of their circle times. Research and theories showed that the circle time is a social training, provide a sense of community and is a ritual that gives a good daily rhythm.The results of the study demonstrate that the circle time is an important routine that occurs for a short time daily in early childhood education. The circle time organizes and structures the day for both children and staff group.

As a leisure time pedagogue I find it hard to have an insight into what children are playing, and how they play when it comes to free play. My experience is that in some free play, conflicts arise, which reveal hierarchies and power structures containing violations, whereas other occasions of free play suddenly come to an end as the pedagogue interferes. In this essay I investigate my responsibility as a leisure time pedagogue during children´s free play, based on two differing play situations. I also investigate the play as a phenomenon by looking into previous research on children?s play and development psychology.

Atlas Copco Tools is a world leading company in tool manufacturing. The productionin Tierp works hard to improve their assembly to maintain its position. This thesis isa part of their improvement efforts to be a more Lean production.The main focus for this thesis was to identify the material flow in the kanban system,which used to supply the assembly groups, focusing on the material flow to assemblygroup 9 and the assembly group 3. Group 3's material flow within the kanban systemwas perceived to perform better than the group 9. The handling of kanban materialand their working methods in the two groups was identify those differences whichaffected the kanban system.As an alternative material supply a study were done in kiting.
