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..

Title: How to manage stress seen from a leadership perspective Authors: Lina Jonsson, Kristian Olsson, Mattias Olsson, Shabnam Tahajjod Supervisor: Marie Aurell Department: Department of Business Administration, IEM Course: Bachelor thesis in Business Administration, FEC 007 Question of issue: How can we understand stress managing at a workplace seen from a leadership perspective? Method: We have chosen a qualitative method for our thesis with inter-views as qualitative data collection. The interviews had a low grade of standardization. Result: On the basis of our question of issue we have drawn the con-clusion that it is important to create comfort at the workplace, that there are a safety and a feeling of handle the work tasks and that there is a plentiful information flow between managers and employees to manage to handle the workplace stress situa-tion..

The aim of this Master?s thesis is to examine how gender is described in some of the most popular children?s picture books in year 2007 and 2008. The theory used is based on Berger?s and Luckmann?s theory about Social construction, Bjerrum Nielsen?s and Rudberg?s theory about Gender socialization, Gens? theory How girls becomes women and boys becomes men and Hirdman?s theory about Gender contracts. The method used is an analysis of ideal types.

Aspects of computerized learning in terms of educational situations in kindergarten andschools where the teachers use software either made for children or for adults, is thesubject of this paper.The market for software produced in Sweden and intended for educatilonal situationswith small children is discussed and analysed by qualitative method. The software, theusers, the producers and other related groups are looked upon from an educationalperspective and a mode1 of this process is presented in the paper.The software is categorized and discussed according to area of use and underlying educationalperspectives. The educational situations in which the users are a part are discussedfrom an educational perspective and examples from use of software in kindergartenand schools are given. The images of their target group which the producers haveare categorized according to phenomenographical method. A proposal of a classificationsystem for software used in educational situations is made..

The following study is a discourse analysis of the concept of critical thinking within pre-school teacher education. It considers the following questions: how does the concept of critical thinking appear in policy documents, central to the pre-school teacher education, and which possible conceptions of critical thinking are conveyed by students and teachers active within the education. Additionally, the study seeks to discuss, as well as suggest a possible relation, between the findings of those two questions. In reviewing the material (consisting of five semi-structured interviews with students and teachers, and of a selection of policy documents central to the education), I argue the existence of a sort of project within the education, which presents critical thinking as a higher value. At the same time, I argue that the concept is not defined or concretized. This project, however, as I suggest while drawing upon Foucault?s ideas of discourse and government, involves a rather high degree of control.

For any animator either working in stop-motion or 3D-animation the knowledge of the first animation techniques are most important. For it is based on these principles that animation today can create such vibrant characters. With the extreme development 3D-animation has undergone the last twenty years it is easy to lose track of the old ways. But with this thesis a hope to show that it is these old ways that will take animation to its next stage. My aim with this thesis is to find out if it is possible to identify the characteristic features of stop-motion and apply these onto 3D-animation with purpose to create a more expressive style of animation.

About 29 000 different services was given by the Swedish welfare state to children with disabilities within the ages 0-22 years before October first in the year 2008. Studies about children with disabilities and their experiences of their situation have rarely been done and it is therefore difficult to know how they think and feel about their lives. Both Swedish law and the UN:s convention about children?s rights states that children have the right to tell their opinion in matters that are of their concern. Thus, we don´t know much about if and how the Swedish welfare state maintain this right towards children with disabilities.

This case-study examines the correlation between young men and democratic instability in group discussions with two analyzing methods in one. One part of the method used is deliberative democracy which aims to explain how democracy works within the frames of discussion in ordinary citizens groups. In this study the citizens is upper level secondary school students. The other part of the method used is the theory pulled by many scholars lately, the demographic impact on democracy. With these two combined in one this study compare the theory of young men as more active in political violence and as a destabilising factor of democracy on country-level with the results of the study in deliberative democracy in small group discussions.

In the construction industry the number of female managers is very low, only four percent (SCB, 2010). In fact, women with management positions has risen by six percentage overall, the last seven years (SCB, 2010). If women in managerial positions continue to grow at this rate, the proportion of women managers will be equal to that of male managers in 2033. More women are needed in the maledominated construction industry in particular because it is deemed that they have a different way of thinking and acting (Granér, 1994). Nelton (1991) believes that companies can take advantage of female managers to be more competitive on the market, the reason why is because women can see other possibilities when solving problems. Rapacioli (2010) argues that the recruitment of women into management positions not only benefits the individual itself but also the company. We have used a qualitative study with a deductive approach. Six respondents from the same company were interviewed, two of them have management positions and the other four were underemployed.The research question of this paper is: What differences and similarities are seen between male and female leadership in terms of their characteristics in the construction industry?The purpose of this paper is to examine similarities and differences in leadership in the construction industry where the focus is on the female and male characteristics. To fulfill our purpose we chose a qualitative study. We have interviewed six respondents at one company in the construction industry. Two of the six respondents have management positions and the remaining four are employed. In this paper we have concluded that there are some differences and similarities between men and women´s leadership in terms of their characteristics.

The purpose of this study was to to examine what teachers think about visual art and how the learning process in this subject does look like. To answer these issues, I made interviews with five teachers of visual art from different schools, and I examined several examples of pupils? artworks. The stories of the teachers were analyzed in relation to governing documents and with assumptions from sociocultural theory, postmodernism and pedagogical - aesthetic research as theoretical point of view.By the qualitative interview method, the observations of the pupil?s artworks, and by the analysis of the interviews with the teachers, I have come to the conclusion that teachers think differently about art but they try to keep themselves in line with the national governing documents.

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

The electrical grid needs to be changed in the future in order to manage more distributed and renewable generation and also to make it possible for electricity consumers to be more active and aware of their electricity consumption. This future grid is usually referred to as a smart grid. With the transition to a smart grid, new challenges occur. One method to determine those challenges is to perform risk and vulnerability analyses. InStockholm, the new urban district Stockholm Royal Seaport is built.

The question formulation for this work has been "is an ice-hockey audience influenced by music during time-outs in a game?". The method was to observe one period with Färjestads BK and Mora IK, but a recording was also made, together with a conversation with the arena DJ. From the recording, the audience reactions were graded from a given scale. The grades were compilated to a diagram that shows the audience reactions in relation to the time, from the first face-off to the final whistle.

The purpose of this essay is to analyse the descriptions of young girls' experiences of internet contacts, which have led up to sexual abuse. The aim is to give additional understanding and knowledge concerning grooming.       Grooming means that somebody gets in contact with someone else with the intention of committing sexual violations at a later stage. In most cases this concerns adults who contact children. We have chosen to confine ourselves to focusing on the grooming on internet that has happened to girls. By means of thematic analyses of texts from the books Jag kände mig speciell, grooming på internet, 2012 and Alexandramannen, vår tids största nätsexhärva, 2009, we have found certain themes and linked them up with previous research-work and also theory of social psychology.
