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.

Anytime-whatever : Om narrativ struktur och temporal upplösning i Stig Larssons Autisterna

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.

Den pedagogiska samlingen i förskolan : En kvalitativ studie om förskollärarnas tankar kring samling

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.

Fritidspedagogens ansvar inför den fria leken

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.

Betydelsen av kolkälla och mikrobiell fysiologisk status för temperaturresponsen (Q10) vid nedbrytning av organiskt material :

The increasing threat of climate change has led to a increased need for models to predict future climat. In these models the changes in the soil carbon pools due to changes in microbiel degradation of the organic matter can lead to both positive and negative feedback-effects. There is however a lack of consensues on the temperature respons on degradation soil organic matter. This paper aim to give a better understanding on the factors controlling the temperature respons. The factors studied were the carbon substrate qualitity and the physiological status of the microorganisms.

Kroppsuppfattningen hos kvinnliga och manliga högskolestudenter. -En kvantitativ undersökning.

Introduction:A good work environment and good resources among district nurses? and general nurses? are important in the provision of good nursing care. For patient security it is also very important that resources and time are used in an appropriate way. A lot of time is spent on non-core activity, for example administration takes more and more time, which can result in feelings of stress.Aim:The aim was to describe how district nurses? and nurses? in primary care perceived their work environment, how their worktime content was distributed and if there was some connection between perceived work environment and the distribution of work time.Methods:A mapping of the content of the work was made in two parts.

Digital delaktighet : folkbibliotekens undervisande roll i kampanjen Digidel

In this thesis the pragmatic pedagogy as formulatad by John Dewey is applied to theswedish national campaign Digidel and its work to spread the digital participation among thegeneral public. The purpose of the thesis is to visualize and problematize that differentunderstandings of a problem, lead to different solutions, as lifted in John Dewey´s pedagogy, thatconstitutes the thesis' theoretical framework. The term digital participation is used by the Digidelcampaign, where public libraries take active part to spread digital participation througheducational efforts. By qualitative interviews with four librarians this thesis examines howunderstandings of the term may vary and in turn lead to differenent educational goals, designsand executions. The result shows that basic computer- and Internetskills are seen as either equelto or prerequisites for digital participation and that the digital participant is seen as either apassive recipient or an active participant.

Hårdfräsning i verktygsstål : Förslitning av skäregg

This thesis work is made by Torbjörn Johansson on Karlstad University for Uddeholms AB. The assignment in this thesis work was to investigate tough cutting in three different tool steels: Vanadis 4 Extra, Vancron 40 and Sverker 21. The research was to compare the wear of the tool after cutting in each one of the tool steel alloys. The research was also made to see if the tool cutting in Vancron 40 has a better wear than the tool cutting in Vanadis 4 Extra and also compare the results with Sverker 21. All three of these alloys are a part of Uddeholms AB:s range of products, and is used in applications like forming tools and knife tools. Vancron 40 is a powder steel with a very good combination of mechanical properties like ductility, adhesive strength and hardness.

Servostyrning med binaural ljudlokalisering

People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.

Tr?stadens dolda utrymmen: fasader i husens mellanrum som kulturhistoriskt k?llmaterial

This thesis explores the narrow spaces between closely built houses in the over 300-year-old wooden town center of Mariestad, Sweden, and their potential as time capsules and sources of knowledge in cultural-historical building investigations. By interpreting well-preserved carpentry work on a facade in one of these spaces, the study aims to provide an example of how these preserved spaces can serve as a source of knowledge and understanding of craftsmanship and the history of the place. The thesis also addresses the municipality of Mariestad's work with cultural heritage, as well as maps out more of these potentially interesting interstitial spaces. Old Swedish wooden towns possess a high degree of uniqueness both nationally and internationally; nevertheless, they are subjected to relatively significant threats of demolitions and substantial changes, often in the form of many smaller restorations or changes over a long period of time. The focus of the case study is a window from the 16th or 17th century and the facade's old, hand planed wooden cladding.

Jämförelse av två mätmetoder för mindre gasvolym

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

Mervärdeskapande i traditionell livsmedelshandel : En fallstudie inom den svenska dagligvaruhandeln

Background: It has been shown that companies that lived under protected conditions for a long time have had difficulties to adapt to major changes. With that in mind an even more extensive low-cost competition in the Swedish grocery market will make a threat for the traditional grocery stores' long-term survival. The question then becomes, which strategies will be successful and lead to higher customer loyalty.Problem: Are the traditional grocery stores using strategies that can compete in addition to pricing and will those strategies lead to long-term survival?Objective: Is to analyse and evaluate two traditional grocery stores' strategies and to examine whether these are consistent with customer demand.Approach: First we have created a more fundamental understanding of the situation in the Swedish grocery market. Then we have implemented two interviews in each grocery store.

Beslutsmodell för inköp och lagerhållning av motorer i ett produktionssystem : En fallstudie på Sandvik

AbstractIt is important to choose which spare parts to keep in stock. With the right spareparts in stock the costs for inventory and production loss will decrease. Cavalieri et al. (2008) highlights that the balance between inventory cost and production loss is underestimated.  It affects the company and must be considered before decision on purchase.The problem with spare engines is that they are all more or less critical for the production. That can be a reason for why no previous research targeting engines and classification of with engine should be kept in stock has been found.

Varumärket Stockholm : En studie om imageutveckling

During my practical training I have seen what after-school offers children. Large groups of children and little staff, often results in that the children had to play freely until they go home. Few activities are offered to the children and the staff is busy looking after the children and ensures that they are not fighting.The purpose of this study is to find out how children feel about their leisure activities and if they think they are being offered a meaningful leisure. The main research questions were:How do children experience their leisure-time?Do after-school offers children a meaningful leisure and is it the children's interests and needs that govern the activities and the environment?How do the number of children in the leisure group affect the leisure time?The methods to collect data in the study are observations and interviews.

Duschhållare

This report will discuss principle, primary and finally manufacturing structure. We were asked to produce a 3D milling to processing the prototype material that is used on the University of Halmstad. From conceptual drawings to produce components for this project have we together with a number of company take developed the right components for this project. We have calculated and analyzed the construction to get the best result for it purpose. Unfortunately have the process to produce the 3D milling has been stopped because of deficient budget and time.
