The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.

The purpose of this study is to investigate childrens possibilities to retrieve information by searching in searching engines designed for children. Two such search engines are examined: Yahooligans and Kids Click, both of which index pages in English only. I have compared Yahooligans with its equivalence for adults; Yahoo, by evaluating the retrieval effectiveness. Some functions in Kids Click and in Yahooligan are investigated. Seven class room studies are described in the prior research chapter.

Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.

This essay is a case study based on two sources of empirical data, qualitative interviews and responses from a questionnaire, which examines upper secondary school students? attitudes to history teaching in a museum context. The students? answers are further analyzed in relation to the concept of historical consciousness. Thus, history teaching in the museum, from a student perspective, and the students? capacity of expressing a historical consciousness in their answers, constitute the core of this essay.

The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.

The Youth Outcome Questionnaire 2.0 Self Report (Y-OQ 2.0 SR) has been implemented in residential treatment centre in the Municipality of Örebro as a result of the strive for a more evidence-based working approach within social work. This study aims to examine how personnel and adolescents describe the treatment/counseling and support and the application of the Y-OQ 2.0 SR in the units. The questions cover the values the personnel and adolescents ascribe to the application of the Y-OQ 2.0 SR, if the result from Y-OQ 2.0 SR is congruent with how the adolescents have been affected during the placement, which obstacles and/or possibilities emerge in the management of the instrument and if there are any indications that the Y-OQ 2.0 SR is advantageous or disadvantageous in the treatment process. The study has a qualitative approach; four interviews were carried out with adolescents and five with personnel. The result shows that structure is an important component in attaining a change in behaviour.

The European Union has been working to promote equality between women and men for a long time. Despite this, Sweden still have a gender segregated labor market where men generally has the leading positions. According to European law the member states shall promote gender equality and to take all appropriate measures. Statutory gender quotas for company boards is one such measure that some of the European member states have implemented in national law. The Swedish law has no provisions governing gender quotas and therefore the purpose of this study is to explain how gender quotas for company boards relate to current law, both of European law and national legislation.

The aim of this study was to describe how adolescents experiences their quality of life, and tocompare if there are any differences in how they experiences their QOL depending on wherethey live, big town or smaller town. The aim was also to examine how adolescentsexperienced their schooling. The study is empirically, quantitative with a descriptive andcomparative design. To measure quality of life a tried and tested instrument ? LifeSatisfaction Questionnaire (LSQ) was used.

This thesis discusses main problems associated with dictionary-based Cross-Language Information Retrieval as lexical and translational ambiguity of query terms, translation of compounds and phrases, dictionary limitation. The purpose of the study is to investigate how query structure influences the effectiveness of CLIR regarding performance of three query types: original query, unstructured query and structured query. Query structuring refers to the application of #syn-operator to group query terms. The study comprises an experiment that was performed in the InQuery IR system with TrecUta database that contains 550,000 news articles from different American newspapers. 24 topics were used for the experiment.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them.

This thesis examines the retrieval effectiveness of two Web search engines. The two search engines are chosen to represent two different types Google as a broad general search engine and Dogpile as a broad general metasearcher. Twenty queries have been used and the first twenty hits for each query were evaluated for relevance. The queries were invented by the authors, based upon their interests and information needs. They were expressed in a general manner, by using one or several keywords, in accordance with the simple search mode available for each search engine.

This degree project investigates how elk, roe deer, red deer and fallow deer can affect an estate in Östergötland. The inventories performed within this project, were completed on an estate in Selesjö, northern Östergötland. This property is used to demonstrate wildlife management. The methods used in this study were originally developed for areas larger than individual properties. Three inventories were completed in the study. These included the recording of the number of droppings and the amount of eaten pasturage, as well as the level of damage on young trees.

The mining company LKAB extracts iron ore in three areas in the north of Sweden, Kiruna, Malmberget and Svappavaara. The iron ore is refined and in the pelletizing plants the material is rolled to finished pellet product. The different steps of pelletizing plants causes among other things emissions to the air. It occurs occasionally stops in the production and the emissions are vented via an emergency chimney without purification. The aim for this work is to look into how LKAB may improve their monitoring of air emissions and control of ambient air quality and the analysis methods which are suitable for measuring.

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.
