In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

This study highlights the differences in articulation, nasality and intelligibility between twenty 16-year-olds and thirteen 19-year-olds born with isolated cleft palate and control groups. The test groups are compared in a longitudinal perspective and based on earlier evaluations of velopharyngeal impairment. Significant differences were found between test groups and control groups using quantitative comparisons based on SVenskt Artikulations- och Nasalitets-TEst and NasometerTM. The longitudinal comparison also showed a positive but not significant development of the speech. Differences emerged in the comparisons based on velopharyngeal impairment but no significance analysis was made.

The aim of this meta-study is to present an overview of the methods used in Master theses written at The Swedish School of Library and Information Science at the University of Borås, where all Master theses from 1999, 2004, and 2009 has been studied. The aim includes examining if there is a connection between college (Swedish term: kollegium) belonging and methods used but also to examine and compare the qualitative and/or quantitative approaches to the methods. In the 252 Master theses studied, 353 different choices of method are recognized. After taking note of the methods, six categories are created in which the methods are placed. The categories are: Interview, IR-test, Observation, Studies of Text, Survey, and Other.

The metal mining history goes thousands of years back. The downside of the mining industry is the large amount of tailings created during the mining operations. Drainage and leaching of heavy metals from these tailings may cause major environmental problems including acid mine drainage and leaching of heavy metals. This study examines a pond located near an old mining site, where part of the old mining facility has been recently (1990) restored. The objective was to assess eventual metal contamination from historical mining and the recently performed restoration using a sediment core as a natural archive of historical metal inputs to the pond.

I rapporten undersöks om det på kort sikt blir någon skillnad i elevers kunskapsutveckling beroende på om de arbetar utifrån ett behavioristiskt kontra sociokulturellt inlärningsteoretiskt perspektiv. Dessutom belyses positiva och negativa sidor med de olika arbetsmetoderna. Studien genomfördes i parallellklasser i årskurs 5 där den ena klassen arbetade sociokulturellt, den andra behavioristiskt, under ett lektionstillfälle. Elevernas kunskapsutveckling synliggjordes och jämfördes genom att låta dem göra en för- och efterhandsdiagnos. Efteråt genomfördes också intervjuer för att få fram elevernas syn på arbetssätten.

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.

During recent years, the trend of Swedish students? negative performance and results in mathematics has been discussed. It is agreed that a change in teaching methods is necessary in order to solve this issue. Thus we found it interesting to take a closer look at an alternative way of teaching. The purpose of this study was to find out what teachers and students associate concrete mathematics with and make a comparison between them.

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 aim of this study was to map the intellectual base at the Swedish School of Library and Information Science (SSLIS) at the University Collage of Borås, and to compare this intellectual base to the intellectual base of the research area Library and Information Science. This was done by analysing the citations in publications published, between the year of 2001 to the first quarter of 2006, by researchers at the institution, using the technique of author cocitation analysis. Cluster analysis and multidimensional scaling, statistical techniques that are traditional i the author cocitation analysis, formed an objective map of the intellectual base at the SSLIS. This map was then compared with three prior studies, that used the same technique to map the intellectual base of the research area. The result shows that the map of the intellectual base at the SSLIS consists of the specialities: user studies, library studies, culture/cultural policy, information retrieval, bibliometrics and information in organisations.

The primary goal of this study was to investigate how the radial growth of retained trees responds after thinning-from-above. The National Board of Forestry which initiated this study, was interested in whether there were differences in the growth-response between the tree species Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.). Another question of issue was if there were differences in the growth response between trees of different sizes. It is within the framework of the National Board of Forestry?s, Continuous Forests Project that these urgent questions are to be answered.

The purpose of this master thesis is to investigate the differences between the traditional way of conducting a reference interview and the electronic way. The main questions of this thesis are: How does the electronic reference interview appear in comparison to the traditional one? How do the librarians experience the differences? Is quality affected in the electronic reference interview? Examples from Fråga biblioteket Ask the Library have been used in this study. The method used in the investigation is based on qualitative interviews in combination with studies of relevant and recent literature. The librarians interviewed all have experience from both traditional and electronic reference work.

This thesis concerns five Gotland Bronze Age cairns. They have been analyzed in order to compare their inner and outer burial - and building context. The analysis then forms the basis for the discussion of the similarities and differences observed. These five cairns along with the cairn Uggarderojr are presented in detail and compared. Major similarities were found between four of the five cairns.

Facebook is today a phenomenon that has connected the whole world. With millions of users this has become an attractive place for soccer clubs to connect with their fans. But in what ways are they using Facebook as a tool to connect with their fans?This essay aims to answer the question if it?s a difference in the way English and Swedish teams communicate with their fans on Facebook. The study was conducted with the use of telephone- and mail interviews.

The purpose of my essay is to highlight the various dilemmas that can occur in the preschool during the moments of guided reflection but also the opportunities it can provide. I am using my own practical experience from situations where care for the children can be questioned and needs to be considered in comparison to the further development of the preschool teachers and with them the entire organization. In my research, I have chosen to highlight the importance of guided reflection, the importance of reliable and secure relationships for children and how these can be eradicated, and finally the importance of ethics for the preschool-teacher?s actions in a given situation.Key questions in my text are; What role does the reflection have in the work at the preschool? How are children affected while this is happening? How important is close and secure relationships for young children and how can they be affected? How can one find a balance between care and learning?By writing my essay I reflect on myself and my own actions. This leads me to a greater selfawareness and greater understanding of my own feelings and my role in the dilemmas I face in my profession.The conclusion of my work is that the preschool organization is not given and it can be constructed in many different ways.

This master thesis was made to investigate the possibilities of using the Matlab-basedsoftware Basegrain to determine grain size distributions of erosion protections onhydropower dams. Basegrain is a photogrammetric tool developed to generate grainsize distributions and other information about coarse flood sediments by analyzing adigital photo of the stone bed. The investigation was made by validating the ability forBasegrain to assess grain size distributions of various materials smaller than the blocksused in an erosion protection by comparing sieving results or manual measurementswith the results obtained by the program. A statistical comparison was then made bycomparing the results from sieving and the program. The possibilities of using thesame method on existing hydropower dams were then investigated by determiningwhether the method was practically viable or not.The results showed that Basegrain generated grain size distributions for coarse gravelthat were very close to the sieving results.
