Simulering av simulinkmodeller med Extended Kalman Filter
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.

Att sätta fingret på emotionell intelligens - En kvalitativ studie om användningen av EQ-test i rekryteringsprocesser
Emotional intelligence (EQ) has been claimed to be the most critical factor in determining a person's success in life, both personal and professional. EQ highly affects academic and job performance, leadership, stress, and well-being but is still not widely accounted for in recruitment processes. During the last 20 years a large number of researchers have shown interest in the concept of emotional intelligence, but few have studied its practical implications and how EQ-tests are used as a selection tool in recruitment processes. To create an understanding of the motivation for using the test, as well as its role in recruitment decisions, qualitative interviews have been conducted with recruiters at companies in Stockholm, Sweden. All interviewed companies use the self-assessment test EQ:i 2.0.
Förslag på riskklassificeringsmodell av ekologiskt kontrollerade aktörer : En jämförelse med andra länders ekologiska kontroll
In order to facilitate trade between EU members, the European Committee has created regulations that will govern supervision of organic products. Every regulatory agency shall, according to the European Committees regulations, carry out a risk classification of each organic producer they regulate. This study for The National Food Administration compares regulation of Swedish organic products with other countries, and aims to produce a simplified model based on risk that can be the beginning of the risk classification model that Sweden in the current situation don?t have. The thesis is based on three questions: 1) What criteria should we use for assigning organic food producers? 2) How do selected European countries and frontrunners rate organic producers and what can Sweden learn from them? 3) How might a national classification model of organic production look in order to ensure an equivalent level of regulation and prevent competition among private inspection bodies? A review of information gathered from the different countries gave differing results.
Utvärdering av metoder för framställning och kontroll av digitala terrängmodeller
Today there are many applications of digital terrain models (DTM) and the requirements of low uncertainty increases. Most of the DTM are produced with Global Navigation Satellite System (GNSS), terrestrial laser scanning (TLS), airborne laser scanning (ALS) and total stations. Guidelines for the preparation and verification of DTM are found in Swedish Standards Institute ? Technical Specifications (SIS-TS) 21144:2007 and SIS-TS 21145:2007. These were defined in collaboration between Swedish National Rail Administration, Banverket, and Swedish Road Administration, Vägverket, to satisfy the needs of requirement formulations in the production of DTM planning, design and construction. The purpose of this paper is to produce and control DTM over Åkermans kulle, located west of the University of Gävle, according to SIS TS 21144:2007 using GNSS with network-RTK, TLS and ALS.
Socker i förskolan : En rörig fråga eller en riktig beta?
More and more preschools are choosing to reduce the sugar consumption. The reason is, inter alia, the increase of weight in the community, but there is also research showing that sugar is harmful to children. The discussions on sugar and children are also a hot media topic.I have chosen to use a qualitative method, interviews, to gather material for the essay. I have interviewed a teacher and a cook in three different preschools, in different municipalities. I have also looked at their various nutrition policies to see how the guidelines for their work on diet and health look like.
Oro för barn som far illa : förskolechefers tillämpning av anmälningsskyldigheten
The purpose of this study was to investigate how directors of preschool apply the mandatory reporting and what information they say is important in the decision to report child maltreat-ment. The study was built on five semi-structure interviews with five directors of preschool working in Greater Stockholm. The perspective of this paper is sociology of law theory. This means to study how out of law information makes sense when director of preschool applies the mandatory reporting. The result was analysed with three different analytic tools: action plan, consulting social services and the considerations of the directors of preschool them-selves.
Modeller för studier av ursprungsmärkt el
The EU has decided that it should be possible for consumers to get information about the origin of the electricity they buy. Therefore, there is a need to examine different systems for electricity disclosure. In this thesis two ways of disclosure have been studied:? Certificate system. A certificate system involves two parallel markets, one for trading electrical energy and one for trading certificates of origin.? Separated Markets.
Lantbrukarens inställning och medvetenhet kring prissäkring
Among farmers in Sweden hedging of product prices is a relatively new way of thinking. A deregulated market and a more volatile price picture are consequences of the free market and the movements towards globalization. The effects of globalization are largely a demand- and supply driven market. These factors give the farmers incentives to stay informed and to act on their own in order to manage their price risk exposure.The overall purpose with this study is to analyze the farmers? attitudes and awareness of price hedging and to examine what type of decision processes that characterize hedging decisions.The study covers the period 2006 until 2008 and the crops oil seeds, barley (malt), milling wheat, feed wheat, oats and feed oats.
Beslutsfattande inom Produktutveckling : Kartläggning, analysering & vidareutveckling av PPM process på ett medtech företag
The number of ideas at innovative companies usually exceeds the amount of available human ormaterial recourses, this include ideas for development of new products. Since they are not able to doeverything they want to do they have to choose between ideas to develop new products. This includesthe decision on when to start, stop or kill a project as well as the thought process of prioritizing betweenongoing and potential projects.Project Portfolio Management (PPM) is an organizational process, with the purpose of systematicallyorganizing and running the activities that aim to evaluate, select and prioritize ideas and projects fordeveloping new products. PPM include four major goals to be fulfilled; Maximizing Value of thePortfolio, Achieving a Balanced Portfolio, Achieving a Strategic Alignment and Running the RightNumber of Projects.The purpose of the thesis was to develop a more visual and formal PPM process for the early stages inproduct development in one department at St Jude Medical AB, Sweden.The thesis was conducted by following a methodology known as Process Modules. The methodology isan approach for developing a PPM process that fits a specific company.
Samlande vs. tillgängliggörande : En jämförelse mellan två förvärvsmodeller på akademiska bibliotek
The aim of this Master's thesis is to examine what effect two different models of acquisition have on user satisfaction with information resources at academic libraries. The two models examined are the traditional model where a subject specialist librarian makes the selection, and the user-governed model where the larger part of the selection is based on user requests. The scope is the libraries of Roskilde University, which employs the traditional acquisition model and Malmö University, which employs the user-governed. Both libraries have a user-oriented approach to acquisition. The study encompasses a close examination of the acquisition policy through document analysis and interviews with the librarians in charge of acquisitions at each university, as well as a user-satisfaction survey among the professors and senior teachers on two faculties at each university respectively.
Ubåtsjaktförmågans utveckling i svenska flottan 1945 till 1949 : ? en analys av bakomliggande faktorer.
Uppsatsen syftar till att förklara de drivkrafter som fanns bakom den intensiva utveck-lingen av svenska flottans ubåtsjaktförmåga under den senare halvan av 1940-talet. Detta sker genom att utvecklingen studeras ur två olika perspektiv med avsikten att finna vilket av dem som har den starkaste förklaringskraften. Perspektivstudien bygger på två statsvetenskapliga modeller vilka har utvecklats av Graham Allison i boken ?Essence of Decision?. Denna studieväg har tidigare använts av andra forskare i liknande syfte med gott resultat.
Price adjustment and vacancies on theStockholm market ? Estimation of rent levelsdue to office-allocations
The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.
Analys, design och konstruktion av en ITS-prototyp : Att övervaka och informera transporter av farligt gods på väg
The Swine flu (H1N1) erupted in 2009 and wasquickly spread over the world and developed into a pandemic, with a great threat against people?s health. It was soon discovered that the H1N1?virus had a different character than the seasonal flu, since it especially affected younger individuals and the consequences from the disease were expected to be more severe. In Sweden it was decided to provide a free of charge vaccination against the H1N1-virus, and the Swedish vaccination ratiobecome relatively high compared to other countries.
Demokratiteoretisk analys av läromedel i Samhällskunskap : En kvalitativ studie om det demokratiteoretiska innehållet i läromedel för Samhällskunskap 1a1 och 1b under GY-2011
This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials.
