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.

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.
Analys av dricksvattenrening med metoderna Mikrobiologisk riskanalys (MRA) och God desinfeksjonspraksis (GDP)
Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.
Cotonouavtalet - egenskaper och orsaker. En studie utifrån liberalistiskt och protektionistiskt perspektiv
The EU has for a long time had a special relationship with its former colonies in Africa Caribbean and the Pacific, called the ACP?countries. This relationship is about to change radically with the new partnership agreement signed in June 2000 in Cotonou. This essay aims to study the EU ?ACP Partnership Agreement from the perspectives of two different theories: The liberalist, free-trade policy theory and the nationalist/regionalist, protectionist theory.
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.

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.
De Paard - Visions of Playtopia
Playsam in Kalmar AB are world famous for their design of the toys they sell. Together with their CEO Carl Zedig the goal was to find a new product for the company. The process has far from been linear, I started off in one direction, got rejected, turned another way and we finally decided to create a rocking horse in a De Stijl style. At the same time taking consideration of the demands from Playsam and myself.Playsam?s products are archetypes of ordinary objects around us such as the car or the aeroplane. The company mainly produces its toys in wood and the stylized shape together with the blank painted surface has become a hallmark for them.De Stijl, the Dutch art movement containing artists, designers and architects such as Piet Mondrian, Theo van Doesburg and Gerrit Rietveld.
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.
Free cow traffic in automatic milking systems (AMS) : a case study on nine commercial dairy farms in Sweden
In Automatic Milking Systems (AMS), cows are kept in a free stall barn equipped with one or several milking units (MU). The cows? activities in the system are called cow traffic. There are three types of cow traffic systems: guided, partly-guided and free. Free systems have no gates, allowing the cows access to the feeding and resting areas at any time.
Sexmånadersregelns förenlighet med EU-rätten
The purpose of this thesis was to analyse if the six month rule in chapter 3 § 9 part 1 in IL is compatible with EU law regarding the free movement of employees and in case of discrimination whether the rule can be justified. First of all the retroactive salary for an unlimited taxpayer and during the period of income earning a limited taxpayer who later became unlimited taxpayer will be analyzed in order to determine if they are considered to be in a comparable situation. An unlimited taxpayer is subject to taxation in Sweden for all of his incomes regardless their origin. However there is an exception according to six month rule, which implies that physical persons who stay abroad due to their minimum six months employment are in Sweden free from their incomes earned abroad if they are taxed in the country of employment. Tax exemption is applicable even if the payment from an employee working abroad is made retroactively.Article 18 EUFF states a general prohibition of discrimination on the grounds of nationality.
[Men det är ju så det borde vara...] : en kvalitativ studie om sex unga kvinnors förhållande till kvinnlighet
The aim of this study was to try to identify what young women see as typically female and how this affects them as individuals, focusing on the female body. How free or limited do they consider themselves to respond to prevailing ideals of beauty, to men and other women. Our questions are how young women construct femininity through the body and why? We do this by using a holistic gender perspective and with the help of key theoretical concepts; gender, normative femininity, heteronormativity, performance, freedom/power and the female body,. We have had a qualitative approach and we have done interviews with six girls in secondary school age.
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.
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.
