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.

Intresset för kartbaserad information på Internet ökar i rask takt. Samtidigt växer önskan av att sprida geografiskt material i form av interaktiva webbkartor utan att vara hänvisad till dyra, professionella GIS (Geografiska Informationssystem) programvaror. Idag finns det en rad open- source lösningar på webbaserade GIS som utan kostnad får utnyttjas, spridas och byggas ut efter egna önskemål. I detta examensarbete undersöks ett 20-tal open-source webbGIS-produkter enligt en allmängiltig mall som vi har tagit fram för att kunna jämföra olika lösningar enligt klart specificerade kriterier. Dessa omfattar bl.a.

The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.

This is a study that will focus on the possibility to learn information about a town and its inhabitants of the 18th century by analyzing individual titles in the church records. The records that are used in this study are marriage registration administrated by the local church of the town of Uddevalla. The records are very detailed and each individual registered have a title, such as ?tradesman? or ?maiden?. Since the source are a registration of all the weddings that took place during the period of 1700 to 1749, the source gives very broad and valid information about the inhabitants of the town.

To achieve the Government's milestones for 2018, which means that 50 % of food waste shall be separated from household waste and undergo biological treatment (composting or anaerobic digestion).   Hultsfred, Högsby and Vimmerby are three adjacent municipalities of Kalmar, county Småland. During 2012 and 2013 analyzes were performed on their household waste to determine its composition. The household waste is currently collected in one fraction. The work, examines how much food waste the household waste contains. From the amount of food waste, the biogas potential is examined - how much food waste biogas generates and how much energy it corresponds to.   Food waste is broken down by microorganisms under anaerobic conditions (anaerobic digestion) in a biogas plant.

The aim with the study is to get an understanding of why pupils read literature in upper secondary school from four Swedish teachers´ thoughts and attitudes towards fiction in upper secondary school. Some of the theoretical starting points that lay as a foundation to the study are Lpf 94, the curriculum for Swedish and different literature oriented researchers as Lars-Göran Malmgren´s subject construction, Louise M. Rosenblatt´s transaction theory, Jan Nilsson´s view on fiction as a source of pleasure and a source of knowledge and Gunilla Molloy´s dialectal questions. To reach the aim in question qualitative interviews with four Swedish teachers in upper secondary school were carried through. The result shows that the teachers see the literature?s part in school as meaningful and claims that it deserves to have an even higher value in all subjects, not only in the subject Swedish.

AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.

Abstract The benthic macroinvertebrate fauna of 22 natural springs on Öland was sampled, by using a time-standarized kick/sweep sampling technique, in the end of September and early October. The aim was to determine the number of species and their abundances in the macroinvertebrate communities in springs and how/why these may change between different springs. Likewise there was a purpose to investigate possible differences between springs considering the proportions of the number of species and the abundances of the five functional feeding groups; shredders, collectors, filter-feeders, scrapers and predators. There was also an aim to investigate if the distances betweeen springs had any influence on similarity between the communities of benthic macroinvertebrates of the springs. Analysis from the springs collected material showed several interesting patterns in the number of species and their abundances when compared between springs devided into groups depending on their environmental factors such as depth and pH.

Companies today need to be more focused than ever on having an active Human Resource Management culture. This is not only because of the companies? concern for their staffs wellbeing, but for the companies? effectiveness in the long run. The reward systems which many corporations use today, to both keep their employees and attract new ones, is a well researched subject by scholars as well as journalists. Earlier research has suggested that it is important to implement an active Human Resource Strategy.

The object of this explorative theoretical study is to compare similarities in three perspectives for evaluation of credibility. The perspectives are the historical method source-criticism, cognitive authority and domain analysis. These perspectives, regarded as intellectual tools for critical thinking in a process of information seeking, by asking questions about credibility related to the social and theoretical context of the intellectual background, can give support in articulating which documents that gives a specific and essential answer to a question. In this sense credibility is seen as a qualitative aspect of relevance. Patrick Wilson argues that we can attain some critical independence towards cognitive authorities and the literature by investigating the social and theoretical topography of a field.

This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..

This thesis deals with subject-based hierarchical search-services on the World Wide Web. The purpose is to investigate how systems of this kind facilitate information retrieval through subject-based information seeking. Its starting point is taken from the study of texts and qualitative analyses of search-services on the World Wide Web. Important aspects and features of the Internet and the World Wide Web are explained as well. Three systems are examined: Mölndals Stadsbiblioteks Länkkatalog, Svesök, and Alta Vista.

This master thesis aims to examine the process of indexing fiction when it comes to area of sexuality and gender identity. The empiric work that forms the basis of the thesis are three investigations:(a) examining the current status of indexing fiction within the catalogues of six Swedish medium-sized libraries;(b) interviewing librarians who allocate the subject headings; and(c) an analysis of the Swedish subject heading system Att indexera skönlitteratur.This will be concluded with an analysis of the gathered material through queer theoretic standpoint with the help of critical classification and its inclusion through separation, and marginalization where subjects that differs from the norm is included but only by being separated from the norm, or ignored totally. This will show that there are similarities with how different groups get treated within the classification systems and how they are treated in subject heading indexing. An example of this in Att indexera skönlitteratur is that heterosexuality never is mentioned in the subject heading but is always present as the silent norm, while gender identity is marginalized through exclusion of the subject heading, and related words are instead being included under sexual identity..

Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

External Thoughts is a studio based project with its purpose to throughworkshops establish contacts and create a dialouge about the content of contemporarygraphic design. The project also aims to apply a design curaticalmethod where the designer is both client and contractor, client and designer.We also wanted to investigate the design content as open-source and examinethe school versus the Internet?s future role in the design and for thedesigner. The project is a collaboration with Rasmus Östgård Ohlson fromBeckmans..
