The voltage regulation in Fortum Distributions medium voltage network in Stockholm does not work satisfactory. This results in too high distribution voltages with many customer complaints as a consequence. The reason is the model responsible for compensating for voltage drops in the distribution network. Despite several adjustments Fortum has not been able to find the source of the high voltages and has therefore appointed an investigation in the form of a thesis work.The aim of this investigation is to locate the error and to produce a proposal regarding the solution of this error using the existing system, common industrial knowledge, state of the art research and the option to use voltage readings from the different substations.The conclusion of this master thesis is that the largest contribution to the high voltage levels is made by the large compensation for distribution loses. Furthermore an additional error in the model has been found.

In this thesis I try to find ways to be more independent and conscious in my interpretation of the music which I am playing. To be able to be more sure of myself and my own decisions I try to find methods on how to achieve this. The methods includes reading articles about interpretation, interviewing musicians and interpret and perform music. The pieces I have chosen are a solosuite by Max Reger, a concerto by Georg Philipp Telemann and a clarinet sonata by Johannes Brahms. I made some concerts where I try to achieve my goals.

The aim with this master thesis is to analyze a scientific material concerning the context between learning and child/student development, and factors which controls process of learning, to create an image with quality account and teaching in mathematics, which then can raise the mathematical knowledge among students.The phenomena which stand in focus for the investigation is: why there is a negative tendency for development of knowledge in mathematics, among the Swedish students that TIMSSs investigations showed in intercultural comparison within the years 1993, 1999, 2003 and 2007.The method is the ethnographical method, which is based on: analyzing scientific theories about learning child/student development, factors which controls process of learning, and factors which controls process of learning the most and qualitative empiric investigation with qualitatively analyzes the questionnaires, which is about factors which are controlling the process of learning and factors which are controlling the process of learning the most.Result of the theoretical and empiric analyzes shows that factors as school environment, attitude for subjects and teaching, controls and influence the learning. To end a unenthusiastic tendency as a negative development of mathematical knowledge among students that is shown in TIMSS investigation and to elevate the students' performance in mathematics, an elevated qualitative account and teaching in mathematics, by the factors named. Safe school environments as the intercultural meeting place, the teachers influence part to the students' subjects' attitude in mathematics and goal related grading criteria in teaching, is all required for e qualitative teaching in mathematics..

The purpose of this investigation was to investigate how being outdoors and participating in physical activities affect the concentration in a collection situation among children.The methods I chose were observation of two groups of children two times each and interviews with four educators.The results showed that the concentration in the collected situation depends on past activity, where it has taken place and that the environment has an impact. If the previous activity been more active and physical the subsequent collected situation is calmer and the children more concentrate. The facts that the children have been outside in an inspiring environment that encourage playing and movement also have a position impact on the child´s ability to concentrate. The collected situation is an important moment in the preschool day when the kids need to congregate and get a chance for social interaction and a sense of togetherness with all the children and teachers. The conclusion is that there is a relationship between movement, physical activity and an increased concentration.

Cryptosporidium parvum is a protozoan parasite causing diarrhoea in many different animal species including cattle and man. It is an important enteric pathogen in neonatal calves and it is the second most common pathogen found in diarrhoeic calves in Sweden. Subclinically infected adult cattle have, in international studies, been shown to shed a low number of oocysts in faeces and this has been recognised as a potential source of infection for new-born calves. The detection methods used for diagnostic purposes are based on microscopic investigation of faecal smears. These methods have a fairly low sensitivity and samples from subclinically infected cattle have to be concentrated before analysis.

There are several different methods of assessment of functional communication in individuals with aphasia. However, these are not very established in Sweden. A number of assessment methods are not translated and adapted to Swedish. The views about what functional communication means are scattered. The purpose of this study was to, with the help of a questionnaire survey, identify how Swedish speech and language therapists assess functional communication, to what extent and what they want that an assessment method should contain to be clinically useful.The study involved 54 clinically active speech and language therapists in the area of aphasia.

Business Intelligence may help organizations in making the right decisions byproviding data for analysis which can be presented to decision makers. DataWarehouse which is a central part of Business Intelligence can be built in severalways but the methods presented by Ralph Kimball and Bill Inmons are considered thetwo main methods. The solution provided by Inmon focuses on integrating the entirebusiness into one large database using relational database development. Kimballhowever proposes dimensional database modeling by creating one or more data martsand integrating these using a data bus. Previous research has shown that the quality ofa Data Warehouse can be measured through critical factors such as data quality andsystem quality.

New energy resources that can replace petroleum diesel are needed and biodiesel may be an excellent substitute. During storage and use, biodiesel can oxidize and form peroxides, leading to degradation of the fuel. It is therefore important to determine the peroxide content of the fuel. In this thesis the triphenylphosphine method, which involves GC-MS analysis has been compared to the standard iodometric method which involves titration with sodium thiosulfate. Working standards were made to see how well the iodometric method worked and also in order to make a calibration curve in GC-MS.
