Transmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes the development of a system that receives digital video signals through FireWire. The standard for FireWire, which is a high performance serial bus, is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s.

Ett digitalt vågfilter av Richardstyp har implementerats i en FPGA på ett utvecklingskort. Sampel kan skickas till filtret och mottas från filtret via serieporten på en dator. Metoden som användes är att en modell av filtret konstruerades i Simulink. Filtret har modifierats med avseende på skalning, brus och stabilitet. VHDL-koden till filtret genererades i Simulink genom att bygga modellen av Xilinx Blockset.

Abstract:According to the curriculum of the Swedish school the pupils should develop their historical consciousness. The aim of this study was to find out which pupils develop this consciousness by listing to an historical novel, talking about that book and writing stories. The study went on for four weeks and the subject of the teaching was the Middle Ages. 28 pupils took part and a variety of methods were used: 1: questionnaire about the lives of the pupils, 2: Making observations of their attitude to the teaching and 3: story writing. The results show that the social background does not influence the development of an historical consciousness.

This study was made to compare construction companies for gardens way to work with up following, with purpose to see if there was an efficient and not resource demanded system which gave much value. To achieve the purpose a case study was made. The delimitation for the case study was only to compare the work with up following on individual project. The delimitation on the companies in the study was from ten to sixty employees. That because to reach companies were it´s not the same person how calculates on tenders and than perform the projects. The study was delimitated to the west side of Skåne. T o be able to compare the companies and to find trends, an interviewguide was made and was used during the interviews with the companies.

We have chosen to analyze how four well known sex crimes were presented in the Swedish national daily newspapers in the 2000s. We chose this topic because sex crimes are considered one of the most terrible crimes. Sex crimes involve the media and upset the society. Our purpose was to analyze if we could identify stereotypes and prejudices about sex crimes in the press reports.The four sex crimes were: Rissne case in 2000, Tumba case in 2003, Hagamannen case in 2006 and the Stureplan case in 2007. We have read all the news stories from the Swedish national daily newspapers Svenska dagbladet and Expressen about our four cases.

The purpose of this study is to examine whether religious behavior or religious identity changes when a person with Muslim background moves to a Christian country and also very secular such as Sweden. I have interviewed five people with Muslim background that have moved from Turkey to Sweden. In this study I have applied Anthony Giddens and Thomas Ziehe's theories about building up an identity but also Nader Ahmadis theory of migration and identity.The results of this study show that there is a change in the practice of religion but also that this differs between these five people who came from the same country. Nevertheless, a change in the practice of religion can on one hand be as a result of modernity and on the other hand, exclusion of family. It also proves that it is not possible to draw general conclusions on this issue instead it should be looked at from an individual perspective..

It is always more demanding and the risk for misunderstanding increases when communicating in noisy environments. The confusions and the mistakes that occur when speech is disturbed are very interesting and happens constantly. The purpose of this study was to examine speech recognition results from the test PB S/N +4 and find out which confusions that are made by the normal hearing and by the hearing impaired persons in the speech lists 3 and 4, and also analyse the mistakes from a phonetic perspective. Ten normal hearing and 50 persons with impaired hearing participated in the study. The people with impaired hearing were divided into two groups; DTMV 40 dB HL.The results were compared between the normal hearing and those with impaired hearing.

The purpose of this thesis is to examine the performance of queries that is expanded before translation in comparison with only translation of the queries using a bilingual dictionary, and also to see if the number of terms that was used to expand the queries was of any importance i. e. if many terms from a thesaurus helped or destroyed a query. To answer these questions i used two online thesauri, Rogets thesaurus and Merriam-Webster Online and one printed bilingual dictionary, Norstedts English-Swedish dictionary. Even though the number of examined queries is too small to draw any definite conclusions, the results suggest that expanding using a general thesaurus may have a negative effect on the queries.

This project report describes a supplement for character creation in a tabletop role-playing game ?Dragons and Demons." The purpose of this project is to improve the character creation for the players? trough the narrative elements such as character?s background story. The applied qualitative methods such as a test panel and a questionnaire were conducted for the evaluation of theories used during character creation and to get feedback on the supplement?s creative value for the players. The aim of the questionnaire was to see how the method for the character creation differs from the regular way of making a character for a tabletop role-playing game and if this idea improves user experience during the tabletop role-playing game.The results of the evaluation are based on answers from novice and experienced players, and conclude that the additional background story creates an insight into the character's past, which makes it easier for novice players to get quick started with character creation.

AbstractTo benefit the economic growth of a country, it is important for the inhabitants to make the decision to become business owners. Sweden today, apart from the rest of Europe, is facing a growing problem. The numbers of companies are growing, but the numbers of company owners are not. As a result of this, the employment is not able to develop under the same conditions, when the opportunities of employment decrease. Research shows, that the interest for owning a company among the Swedish youth has increased.

When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.

This study aims to analyze the risks with building new households between railroads and shore, the focus of the study lays on Öbacka strand in Umeå municipality. The study also investigate if a land use conflict has taken place and how it was handled.The paper is based on different documents that was central for the work of planning the households and some interviews with operators that was highly involved with the planning of the area.The results shows that there is several risks with establishing new household between railroads and shores. Mainly because of the exposure of noise from the railways, though the risk for impact on the living environment for animals were low in this case there is a generally risk that it could get negative effects. It also a very important that the availability to the shore is secured. Planning in this type of area involves a great number of operators can easily cause a conflict due to the different perspectives on how the land should be used in the future, and also because of protecting different interests.

The study is quantitative and the purpose was to examine the effects of ethnicity and education on three working-related identities and striving among 80 participants. The participants consisted of foreign-born people living in Sweden and people who were born in Sweden, with different educational background. Each groups consisted of 20 participants. The result showed that the highly educated participants had higher professional identity. The participants with lower education level had a stronger colleague identity than the higher educated participants and the Swedish-born participants had a lower identity.

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

The background to this project came from my interest for letters and how to make a typeface. The result is the lowercase letters for this typeface, and the journey to learn the process of making it..
