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.

Detta examensarbete hade som syfte att undersöka hur förmedlingen av förvÀntningar ser ut i en nÀra relation. FrÄgestÀllningarna handlade om huruvida olika kommunikationsstilar hade nÄgon pÄverkan och om det fanns skillnader mellan mÀn och kvinnor, eller beroende pÄ hur lÀnge paren hade varit tillsammans, nÀr det gÀllde förmedlingen av förvÀntningar i en relation. Social Exchange Theory (Thibaut & Kelley, 1959) har anvÀnts som grund för undersökningen eftersom den ger en tydlig förklaringsmodell över förvÀntningars inverkan pÄ en relations tillfredstÀllelsegrad. Metoden som anvÀndes var av kvantitativ art dÀr enkÀter var det instrument som tillÀmpades. EnkÀterna fylldes i av 13 par som hade varit tillsammans i minst 6 mÄnader.

Regional European Offices with the purpose to represent regions and municipalities in the EU-system have had a substantial expansion over the last years. One example is the North Sweden European Office for the counties of Norrbotten and VĂ€sterbotten, consisting of seven different headmen who are representing both the private sector as well as the public system. This diverse leadership representation makes North Sweden a very good example on a so called Quango, organisations that stand under simultaneous influence from both public and private sectors. These Quangos opens up new possibilities to solve public problems, but they also bring together two different working models which is not always easy to handle for a Quango. According to earlier surveys some characteristic Quango problems within North Sweden exist, for example the ability to prioritize and thereby be as effective as possible.

On the 8th of May 2007 a local power-sharing goverment consisting of Sinn Fein and the Democratic Unionist Party (DUP) was formed in Northern Ireland. The aim of this dissertation is to explore why the DUP, who in the past have opposed all forms of power-sharing decided to form a goverment and take active part in a power-sharing agreement. The study is based on a consociational theoretical framework developed by Arend Lijphart and further developed in a Northern Irish context by John McGarry and Brendan O'Leary. Using this theory the study seeks to understand the broad conditions surrounding the DUP's power-sharing. After a description of consociational theory and the road leading up to the Belfast Agreement,three possible explanations for power-sharing, based onconsociational theory are discussed.

Recently, the selections of ethical funds are increased; at the same time investors with social and moral preferences have increased in the capital market. There are currently debates on whether ethical funds perform better or worse than funds without ethical criteria. This also involves a vivid discussion on whether investors know about the consequences of investing in ethical funds. Therefore, this study involves theories about the rationality and decision theory, in addition to what mainly control the investment decisions. The study also discusses portfolio theory since this is one of the underlying theories behind fund management and its development.The purpose of this study is to explain if ethical limitations in the selection of securities affect risk and return in the fund portfolio.

? Does Karlstad municipality have adequate institutional conditions to make the best use ofthe citizens? proposals??The purpose with the thesis is to investigate if citizens? proposals lead to a broader politicalinfluence. To answer that, I have done a case study about how Karlstad municipal administers citizens? proposals. The research assignment is: Does Karlstad municipal have adequate institutional conditions to make the best use of the citizens? proposals? The perspective is a democracy perspective and the theory is institutional theory and policy process theory.A selection of citizens? proposals that have arrived to Karlstad municipal between 2008 and 2010 have been studied in detail to analyze how the proposals have been administered and if it matters how the proposals are phrased.

It has been observed by both onion producers and a plant protection advisor on Öland (an island off the east coast of Sweden) that basal rot is the largest contributory factor to reduced onion quality and yield. Basal rot is mainly caused by species of Fusarium fungi. The aim of this study was to: a) investigate which species of Fusarium that can be found in onion produced on Öland, b) describe the symptoms caused by the different Fusarium fungi found and c) explore, through interviews with the onion producers on Öland, the mechanisms that may be involved in the observed increase in basal rot.Onion bulbs (Allium cepa) were sampled on two occasions. In total 181 onions from 11 different fields were analysed. In addition, eight onion producers were interviewed.

This study aims to examine play as a phenomena from a phenomenological approach. This I do by discussing a dominant approach to play, an perspective which is reproduced in the context of pre-school and in where the play and learning is in single focus. Using alternative perspective on play, mainly by Gadamer and Bakthtins philosophical thoughts about the feast or the carnival, contents differ significantly from educational or developmental psychology perspectives. I open up for an understanding of what play as ontology can be understood as, and thereby enable second readings. I illustrate this thought by an empirical example from a pre-school context which where created alongside with the children in the study.

The following report is a constructive responsive evaluation of Svalövs communes unit for newly arrived refugees based on a qualitative user- and stakeholder model. The main purpose is to evaluate the units? quality from a user and stakeholder perspective. The main findings are that the users and stakeholders are satisfied with the quality of the units? services but request further social and structural participation.

The aim of this study was to examine care managers and how they understand and use their discretion. We used a qualitative method and the data was gathered by semi-structured interviews. We interviewed eight care managers in four different municipalities in southern Sweden. The theoretical approach we used was Michael Lipsky?s theory about street-level bureaucracy.

The purpose of this study is to examine young adults', 18-19 years old, attitudes towards corporal punishment and with the help of social constructionism, grid-group theory and relevant concepts analyze the results and compare it with previous research. The research questions introduce various factors such as gender, origin and personal experiences of corporal punishment that may affect the attitudes. In order to fulfill the purpose and answer the research questions, a quantitative research method has been selected. There was 118 participants in the survey. The study was conducted by means of surveys in high schools in Örebro. Social constructionism made us realize how the community, perceptions and expectations might influence attitudes. Grid-group theory gave us an insight into how different family structures may explain why attitudes toward corporal punishment of children differ between individuals.

Whist is one of the most played card games of the world. Though there have been many studies made in the field of game theory, whist is still somewhat of an unchartered territory. In this thesis some methods to obtain an optimal strategy for whist are discussed. Whist belongs to a group of games called logical games. For this group there exists algorithms which result in an optimal strategy.

The purpose of this study was to examine how teachers practice Arne Tragetons theory of using computers as the first writing instrument in reading and writing development. We wanted to clarify how the work from using Tragetons theory was applied while investigating if and how other methods of reading and writing instruction were used. Our interest lays in how the teachers accomplished the knowledge of this theory and also how the choice of this approach came about. To investigate this we used interviews with a qualitative nature, where seven active teachers were interviewed. They worked in three different schools in years one to three, they were all women and had various long experiences of work on the computer writing tools.

The title of the paper aims at a comment by one of the students during an interview. It reflects how most of the students experience the lunches in a specific school where the investigation is made. The question of pedagogical lunches has always interested me. Here I have used a method called the Grounded theory. I carried out a qualitative investigation with a number of methods such as interviews and participating observations.

The aim of this study is two folded. We wish to investigate if there is a value premium from hedging jet fuel exposure for American and European airlines. We also seek to answer if airlines can affect their probability to default by using Risk Management. During the period 2003 ? 2006 there existed a value premium for airlines that hedged their expected future consumption of jet fuel.
