Vektorkvantisering för kodning och brusreducering

This thesis explores the possibilities of avoiding the issues generally associated with compression of noisy imagery, through the usage of vector quantization. By utilizing the learning aspects of vector quantization, image processing operations such as noise reduction could be implemented in a straightforward way. Several techniques are presented and evaluated. A direct comparison shows that for noisy imagery, vector quantization, in spite of it's simplicity, has clear advantages over MPEG-4 encoding..

Föreningsengagemang och politiskt deltagande ? en tvetydig historia : En studie av Högsby och Växjö kommunfullmäktige

AbstractThe political parties in Sweden are losing members. This is seen as a problem because the political parties are the base and the recruiting ground for members to decision-making bodies. Social movements are seen as a place where people with a modest background could express their opinions and also learn the political process. These movements have also lost members during the last decades and this could seriously affect the representation of lower social groups among the decision-makers. This essay emanates from Robert D.

Ljudinstallationer i Sveriges utemiljö

When visiting Scaniaparken in Malmö you have the possibility of listening to music streaming out of grass-covered hills. In Helsingborg children can compose their own music and play for their friends on the playground. On a square in Nacka Strand you can hear birds singing in the quiet intervals of traf?c. What the places have in common are that they all contain sound installations.

Jag gör det själv / Allt blir bra : Ett examensarbete om att hjälpa sig själv

The problem being examined is the disturbing noise that is created in an open plan office on a company working with a creative process, such as a newspaper or a communications agency. The purpose of this study was to examine the needs for today for a sound absorber in open offices and create and design a design proposal. The aim is also to develop a marketing material the product proposal. The problem has been broken down into the following questions:- How does the user look at the need of a sound absorber in an open offices solution today?- Does an interior designer apply sound absorbers when they furnish the intended environment? - How can a design that meets the needs that exists be achieved and to speak the user?The study is based on three choice of methods a literature review on selected topics that relate to the topic, an interview with an interior designer to explore how an interior designer applies absorbers in open plan office and finally an extensive survey that treats the user's needs and appropriate appearance for the product proposal.The design process has undertaken the following methods, design brief, requirements specification, functional analysis and sketches to produce the final product proposal.

Etnicitet och sociala relationer : en kvalitativ studie av hur nio elevers etniska bakgrund påverkar deras sociala relationer i skolan

This study aims to examine how the students ethnic background affects them in their social relationships at school. The main research questions in this study have been: How does the ethnic background of students affect there social relationships with their friends at school?How does the identity creates and develop in the context of social relationships? What significance does the language that is spoken hold in the social relationships of the childrenThe main research questions have been investigated based on the students perspective, where the two main methods were individual interviews and observation on the schoolyard during recess. The interviews and observations where carried out at eight informants with three different ethnic backgrounds. The three ethnic backgrounds were Swedish, Somali, and Syrian.           The results of the study showed in the interviews that no one of the informants differentiated themselves from their friends who came from different ethnic backgrounds from which they did, they did not categorize themselves based upon their ethnicity.

En mångkulturell skola : En studie om främjandet av elevers kulturella kunskaper på en mångkulturell skola

My thesis is based on a qualitative study. The purpose of the study is to investigate whether the educationalist at an especially chosen school in Stockholm promotes the students multicultural background in the education or not.This is due to the fact that the Swedish school to a considerable degree reflects the multicultural Swedish society. The socio-cultural starting point is when people come together and meet. The language is the tool of the socio-culture and it is the dialogue, discussion and sympathetic understanding that makes people meet.The cultural concept is diffuse and very wide. Everyone has their own definition of it.

Har musik betydelse för studieresultat

The purpose of my study is to examine if the total study results differ between music classes and regular classes. Are there higher grades in music classes? If so, what are the causes for this? I chose to make an inquiry at two schools in different town districts, with music classes. At those schools I also collected data of pupils grades, and was informed by the principals and the music teachers about the activities. The number of respondents were ninety.The inquiry showed that the grades were markedly better in music classes, and that you can see great differences in well-being, parental engagement and ambition level, compared to regular classes.

Ickevåldsremix : En dröm om hur ett samarbete mellan Moder Teresa och The Knife skulle upplevas.

This is an art-remix project that focuses on a dream about art and music remixed and made within a context of nonviolence. The goal is to create temporary (and in the long term hopefully stabile) spaces of peace. It will be done within places where change needs to come, where it needs to be heard/seen/experienced. Weapon exports from Sweden are increasing even though there is research showing that nonviolent resistance in conflict is more effective. In this essay I discuss nonviolence and how I can implement that in my work to find a meaningful work for both me and my neighbours.

Hållbar byggnad med hänsyn tilltrafikbuller Utformning av ett bostadshus i ett trafikerat planområde i Örebro

De flesta av Sveriges kommuner har ett mål där de strävar efter att bygga ett hållbart samhälle, vilket innebär att man utnyttjar den befintliga infrastrukturen. Målet med detta är att dra nytta av de obebyggda områdena i stadsbilden genom att bygga nytt. Eftersom de tysta sidorna av byggnaderna ska ligga på en ljudnivå under 45 dB(A) har det här examensarbetet behandlat de möjliga lösningar som kan tillämpas vid bullerdämpning. En platsinventering har utförts där de olika förutsättningarna har studerats, och där resultaten av studierna har granskats med syfte till att planera en vision.Nyckelord: Bullerdämpning, bostadsutformning, platsinventering.

I mötet mellan två världar: En studie om förändrade chefsroller i sjukvården

Swedish healthcare has experienced increased economic pressure during the last decades and organizations have faced many changes. Managers and their roles in organizations have also been affected by the changes. Traditionally, managers in the healthcare sector are highly specialized doctors with a strong medical background. In the thesis, we study a big private healthcare company with an ambition to lead the development in the sector. In order to accomplish its goal, the company is trying to change the organization of managers.

??från att vara ett föremål av guld till en ?rostig metallbit?.? : en rättssociologisk studie, med en diskursanalytisk metod, av domar med hederskontext

This paper discusses honour related crimes and the judicial process within the legal system in a Swedish context. The empirical base of the study is four cases, with an honour background, and we have used discourse analysis as our method. We have developed four tools for analysing the sentences with which we observed aspects such as; language, the roles of victim and perpetrator that the involved can undertake, the different identities that the sentence might create and finally how the stories change when they enter the legal context. We connect our results to our theoretic backgrounds such as Kolfjord who discusses the legalization of conflicts, the holistic and individual perspective, the legal system as a theoretic background and finally the UN:s definition of honour crimes. These four theoretic perspectives have helped analyse the empiric base.

Simulering av simulinkmodeller medExtended Kalman FilterTidsoptimering av integrering

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

Inredningsförslag till Bolandgymnasiets matsal

My bachelor?s dissertation concerns the creation of a proposal for interior decoration of the Boland High School?s canteen. I have been in contact with personnel, students and the school principal through the duration of the project. In the end, substantive changes of lighting, interior decoration and movement were proposed for the canteen. In the proposal I have focused on accentuating the school?s profile, on creating smaller spatial configurations within the larger configuration of the room, lowering the noise level, creating a good movement flow, increase the number of seats and creating a pleasant environment in which to eat..

HÖGSKOLEBIBLIOTEKARIER OCH ÄMNESKOMPETENS : En undersökning av ämneskompetensens betydelse för högskolebibliotekarier i Skåne

The aim of this Master's thesis is to investigate the importance of subject expertise for academic librarians in Skåne. Virtually all librarians in Sweden have studied other subjects besides library and information science (LIS) before becoming librarians, and in this thesis we ask what happens to this expertise. How many librarians can be said to have a good background in the subjects they are working with? Do academic librarians use their subject knowledge on the job? Does it make a difference what subject one has studied when it comes to job opportunities? What do librarians themselves think of the importance of subject expertise? We are also interested in finding out how subject expertise fits in with the growing professionalization of librarianship.A quantitative questionnaire was sent to 195 academic librarians at four different institutes of higher education in Skåne. A total of 107 librarians answered questions about their LIS education, subject background and current job as well questions on how important they perceived a subject background to be for themselves and for academic librarians in general.

OMBYGGNAD AV TRAFIKPLATS : Ekhagsmotet i Jönköping

We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.
