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..

The purpose with this essay is to study if the exhibition, Maria-Drömmen om kvinnan has a gender perspective and if it contributes to the history of art. The study shows what kind of women the exhibition illustrates and what kind of perspective it has. By telling about the black Madonna I also show that there is another representation of the middle age women in the Roman Catholic Church at this time that the exhibition not have included. The study is also going to illustrate the difference between a genderperspektiv in art and a women?s perspective.

This study aims to highlight and analyze eight secondary teachers' views and thoughts on mathematics. Hopefully this study will provide a deeper understanding of how teachers think and reason about their subject and how this affects their teaching. The study was conducted using a qualitative interview method, based on interviews with eight middle school teachers who teach in school mathematics for grades 6 - 9. The interviews were recorded and then transcribed and analyzed. After the interview analysis one can conclude that the teachers? thoughts concern three main themes: the importance of mathematics, children?s lack of basic knowledge and the teachers? lack of time.In discussion and analysis the teachers conceptions of the own subject is being analyzed, and that is the foundation of this study.

The Swedish cooperative Lantmännen Ekonomiska Förening has initiated a project labelled "Operation Blåljus" that includes an extensive program for closing down elevators. The number of elevators will be reduced from 92 to approximately 15 after harvest of 2007. The objective of Blåljus is to increase the price of grain with 10 öre/kg. A project has been initiated at the Lantmännen Grain division where the purpose is to provide the farmers with support in their decisions and practical advice how they can load a 35 ton grain truck on 30 minutes. The result from the project will serve as a support system to the farmer in his ambition to achieve cost efficient systems to load a truck with grain on the farm.

Studien undersöker hur man på ett praktiskt sätt kan knyta samman musikteori-, gehörs- och ensembleundervisningen. Syftet är att undersöka möjligheten att i jazzsammanhang träna sitt gehör i grupp vid sina instrument. Jag har utvecklat tre gehörsövningar som undersöks i den här studien. Övningarna är konstruerade så att exempelvis pianisten skall övas i att höra basgångar, medan basisten övas i att höra ackordläggningar. En av ensembledeltagarna (piano, gitarr, sång, blås eller bas) styr övningen och väljer hur ackordföljden ska fortsätta genom att följa vissa regler (exempelvis upplöses dominanter alltid ren kvart upp/ren kvint ner).

The thesis is a case study that deals with public space based on how people use them. Public spaces are an important part of our city life and everyday life. Quality public spaces and places are due to its design and use, which are the primary aspects of this study. Hässleholm has been the location for the case study inventory items. Five different methods have been the basis for the study, and through them it has been possible to study what makes a room usable and unusable and what criteria is necessary for people to want to stay in the public rooms.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Does low fat dairy products reduce blood pressure?Author: Emma Bergman and Naman LimaniSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 26, 2014Background: It is estimated that at least a third of the population in Sweden have a high blood pressure with genetics, unhealthy diet and physical inactivity as the main contributing causes. High blood pressure is one of the greatest risk factors to develop cardiovascular diseases, which is the leading cause of death worldwide. Milk is a nutritional food product and previous research suggests that low fat dairy products may have blood pressure lowering effect.Objective: The aim was to examine the scientific basis of how low fat dairy products affect blood pressure.Search strategy: Twelve searches were conducted on PubMed and Scopus, where the chosen search terms were combined to produce a broad search as possible in the particular area. The search terms used were dairy, dairy products, milk, blood pressure and hypertension.Selection criteria: Studies on normotensive or hypertensive individuals who received low fat dairy products were included.

This thesis is based upon the work done at Westinghouse electric company (WEC)inVästerås during the spring semester of 2015 and describes the development of a quickcoupler with associated blade changing tool. These are meant to be used togetherwith a sawing tool that the company uses for the dismantling of nuclear reactors,which is performed under water.The aim of the thesis was to develop a complete manufacturing documentation withdrawings and related CAD models which Westinghouse later can use to manufacturethe tool and the quick coupler. It was also included in the assignment to, if necessary,modify parts of the saw tool to adapt these to the intended blade changing tool.A number of visits to the company's workshop was made during the time to study thesaw that the thesis is based upon. The purpose of these visits was to get a better ideaof the dimensions, construction and the field of use of the saw. On three of thoseoccasions various engineers and consultants accompanied us to discuss possibleproblems with different ideas.This was interspersed with information in the form of literature studies on quickcouplers to create a clearer picture of the nature of the task.When enough information had been gathered a functional analysis was made to dividethe main problem into subthis phase the idea and concept generating process took place.The methods used for this was mainly brain writing and brainstorming.

The aim of this study was to get a survey and a deeper understanding of students? choice of language at upper secondary school, as well as their attitude and motivation to the German language. The rapports of diminished interests in studying languages at upper secondary school raised our interest in how to go against this and motivate students to actually choose to study a language. The study parted from a student perspective with focus on learning, attitude and motivation. A quantitative study with 168 pupils from 11 secondary schools in Halmstad as well as short interviews with their teachers have been used and analysed.Our study showed that students are not particular interested in German.

Syftet med följande arbete är att undersöka om och hur Learning study som är en metod att granska, analysera och utveckla pedagogiken, kan förbättra undervisningen i teater på gymnasiets teaterestetiska inriktning. Jag vill säkerställa att kommunikationen i undervisningen fungerar och förbättrar deras kunskaper gällande begreppet närvaro inom teaterämnet. Enligt den ryske teaterpedagogen Stanislavskij så innebär närvaro en överensstämmelse mellan skådespelarens övertygelse i karaktären och det uttryck skådespelare och regissör vill förmedla. (Järleby, 2001, s. 174-175.) I detta arbete har jag även reflekterat och redogjort för tidigare forskning genom två studier inom Learning Study och en studie i teater.

This master thesis is the documented work of the construction process and testing of a three hour laboratory session in mathematics aimed at high school level students. The purpose of the thesis was to create an interesting laboratory session for the science education center ?The House of Science? that could be used as a part of their regular program directed to schools. The thesis explores the possibilities for how one can construct a laboratory session on the topic ?molecular symmetry? as well as the underlying pedagogical theories used to describe learning processes in creative contexts.

Equestrian sports and the interest in horses have existed for hundreds of years. It is only in the last thirty years the technological development have enabled closer studies of equine locomotion. The production of both soft- and hardware that manages to capture and analyze the fast movement of the horse has resulted in a large increase in locomotion research. Even though the interest in horses and the different disciplines they compete in is great, there is a small understanding in how the rider influences the movement of the horse in different types of training. There are several studies available where horses moving freely without the influence of a rider have been studied. What happens with locomotion and ground reaction forces when a rider and equipment are added is not well studied. The objective of this study was to investigate if there are any differences in the ground reaction forces between sitting and rising trot. The study contained seven horses. Six Grand Prix dressage horses and one dressage horse competing at intermediate level.

The main purpose of a logotype is to harmonize with a company?s business concept and culture. This study is based on the receiver?s attitudes about three different logotypes - Volvo, Telia and Mcdonald's. It informs the reader about the importance of a logotype as a mean of communication and if the perceptions of the logotype harmonize with the profile of the company.

In Sweden, the labour movement historically had influenced both society and politics. In recent times, it is considered a change in society with a stronger employer party while the unions weakened by reduced unionisation. This study aims to highlight the presence of individualistic and collectivistic approaches to the labour market in relation to union density. The different approaches are investigated in the labour market by means of a quantitative survey. The study's survey items are workers in the timber industry.

This thesis has been carried out at the Department of Urban and Rural Development at SLU Ultuna during the spring semester 2009. The topic of the paper is how energy consumption can be influenced through design and if the conditions for good design decreases when solutions based on energy efficiency are used. The report is divided into one literature study and one part where energy efficient solutions are used in a design. The thesis work has its origin in a project called "Energihus i Uppsala." The planned building will be a center for energy research in Uppsala. The project aims to demonstrate to the public what is currently happening in research related to energy.
