The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

This paper set out to investigate how teachers of Swedish in Sweden implement the grammar objectives of the curriculum in their teaching, through interviewing six teachers. It has been important to compare their methods to modern research of grammar teaching and teaching in general. They have been asked a series of questions to answer whether or not they use grammar terminology as mediating tools, if they intergrate dialogue among students in grammar teaching and to what extent the teachers? knowledge of and attitude towards grammar influence their teaching methods. The results show that grammar is used as mediating tools primarily when it comes to feedback on pupils? texts, though not to a great extent; dialogue between pupils is rare when it comes to grammar teaching; and the teachers? grammar knowledge and attitude affect the teaching methods, primarily in the sense that seeing value in grammar knowledge increases the teacher?s desire to develop new methods for grammar teaching..

The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. These are adapted and developed according to what should be tested and to what can be tested in CD7, which has been the object. With CD7 different climates can be simulated in a controlled environment for complete truck level, from desert with high sun load to arctic cold and snow.The test methods represents a basis to start from, for designers and test engineers which make the testing more repetitive as well as time eventually can be saved. Before the test methods can be applied they must be verified as they are based on theoretical and empirical assumptions.

This is a study in the field of Music Information Retrieval (MIR) concerning classification of musicgenre. The study uses a music listening experiment and machine learning methods to determinewhether or not the drum sounds from different songs contain sufficient information to classifygenre.MIR methods are used to extract data from the audio signals. The data is used together with theclassification results of the listening experiment to train different machine learning algorithms toclassify the songs in different genres.The results indicate that using only drum sounds for genre classifications works well, both forlisteners and for machine learning methods..

The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.

Within the literature and film sciences there are clear models of storytelling and methods of creating a good story. In the game industry it's more difficult because the games are often non-linear, and games are a less established medium than the other two. With this study our purpose was to examine game developers and methods they used when creating a videogame, with focus on storytelling. Four interviews were made with representatives from four different videogame companies in Sweden. The information from the interviews was put in relation to theories regarding the structure of videogames and an established model for creating videogames.

Sparse matrices are often used in numerical algorithms that solve linear equation systems. Many methods for storing sparse matrices have been proposed and implemented during the years. These methods focus primarily on minimizing the total memory consumption and the time that it takes to store a sparse matrix. This report researches the available storage methods for sparse unstructured matrices. The formats that are researched and implemented are COO, CRS and ELL.

The purpose of this study is to examine how educationalists work with bilingual children's language by looking at how and what approaches are used to encourage language development. I have chosen to compare two educational philosophies: Montessori and Outdoor Education, to see how big the differences / similarities are in working methods. The background to this study is that preschools uses various approaches and have different methods to stimulate the children. This means that the conditions for children's language development might look different depending on the preschool they go to. The information used has been gathered through interviews, where I have taken note of educationalists thoughts on their working methods, and through professional literature dealing with this topic.

This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.

As Sweden has become a multicultural society the need for developing new educational approaches rises. The preschool is a crucial piece in this as it is the one of the first institutions where the children start to develop the language skills. The aim of this study is to investigate the language development approach as practiced by teachers, in their preschool programs, and determine if the teachers work methods can be considered intercultural. This is done to gain a deep understanding on several language development methods and analyze the teachers' approach within the framework of intercultural pedagogy perspective. The theoretical framework used in the study is the intercultural perspective.

This master thesis has been carried out as a prototype development project. The project hasbeen performed in cooperation with ÅF Combra AB. The purpose with the master thesis is toconstruct a Bluetooth interface between an accelerometer and a smartphone and constructinga physical prototype containing an accelerometer. This is done to test a new user interface tomobile phones. The master thesis has also included a research about the possibility toimplement distance measuring with Bluetooth.

Smartphone applications, or apps, are an increasingly important part of omnichannel retailing. While the adoption and usage of apps for communicating with consumers has grown exponentially over the past few years, there is little academic research in this area. The primary purpose of this thesis is to describe how the involvement in a product category affects consumers' intention to use a retailer-branded smartphone application during their shopping trip. Drawing upon recent IS-literature with models TAM and UTAUT, our results indicate that product category involvement constitutes an important factor on the intention to use a retailer-branded smartphone application. By viewing involvement as a multidimensional construct, our study shows that the degree of hedonic and expressive value a product cateogry provides consumers with has important effects on intention, and these relationships are not moderated by consumers' age.

The aim of this study is to describe and analyse the knowledge of three of the treatment methods used in youth welfare and this is accomplished through a knowledge review. This study contains an analysis of three different treatment methods described in eleven different peer reviewed articles. The articles are all internationally published between the years 2006 to 2012 and they are all effectiveness evaluations. The articles deal with treatment methods concerning Motivational interviewing (MI), Aggression Replacement Training (ART) and Cognitive behavioural therapy (CBT) and these are three of the most common in youth welfare in Sweden. There is not much knowledge of Swedish conditions and that is why this study focuses on international research.

The purpose of my study is to contribute knowledge about how class teachers can work with students who are in mathematics difficulties. The question at issues I have is: Which methods can class teachers in grades 1-3 use to help students with mathematics difficulties? and Which obstacles and opportunities are there in this work? To get answers to my questions, I have read relevant literature and interviewed 3 class teachers in central Sweden. Through my interview I learned that education should include and build on concrete materials and methods. I also got to know that time is the biggest obstacle to helping students with mathematics difficulties. Keywords: mathematics difficulties, methods, obstacles, opportunities.
