This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new electric motors for AtlasCopcos electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.

Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

This report represents a comparison between two different tools used to create an online store that was developed by two students at the Technical University in Jönköping. The web shop will be of great benefit to both customers and administrator in a food firm known as Mattias' Livs. The company wanted an online store that facilitates the sale section and gives a full control of their stocks. The aim of this thesis is to create an online store that offers customers the ability to shop online and help the staff to operate the company in a simpler and more efficient way, which reduces the need for human resources and thus leads to less costs for the company. The aim also includes a comparison between the two different tools used to create the online store.

Learning Management Systems (LMSs) hold great potential to support learning activities, for example by providing teachers and students with new and extended spaces for interaction and collaboration. However, this potential appears to be difficult to realize, and despite their perceived learning benefits, the reality is that LMSs are being used primarily for administrative purposes. Meanwhile, external pedagogical tools are successfully put into practice to improve learning outcomes, and the aim of this study is therefore to identify and discuss benefits and disadvantages associated with the LMS as a concept. By interviewing secondary school teachers, we disentangle the idea of integrating administrative and pedagogical aids into a single platform, providing detailed insight into the use of digital tools in secondary education. The study contributes to a deepened understanding of integrated learning environments, and we conclude that there is a conflict between structure and flexibility that needs to be addressed before determining the design of a digital learning space..

???In this thesis I discuss the adaption of the speaker to the audience, and suggest a radical re-imagining of both the act of adaption and the reasons why adaption is necessary. My main purpose is to introduce social complexity into what I see as the pivotal point of both classic and modernrhetoric and thereby create new possibilities for future research.I accomplish this by modifying the rhetorical concept of doxa, moving from Pierre Bourdieu's separation of doxa and habitus ? the incorporated form of shared beliefs and values ? to an integrated view based in Manuel DeLanda's use of Gilles Deleuze & Félix Guattari's concept of the assemblage. In this way I formulate a notion of doxa that emerges from social interaction while at the same time shaping and regulating it.

This paper discusses the relationship between rhetoric and hermeneutics. It is a studyconducted through a generative method where two different rhetoric students haveanalyzed three rhetorical objects and afterwards have compared their results and theninterpreted the differences and similarities. The purpose is to find what makes aninterpretation legitimate and plausible and what binds rhetoric and hermeneuticstogether through meta analysis. The study shows that doxa is a fundamental elementthat connects rhetoric to hermeneutics and that it is more relevant to discussintersubjectivity than legitimacy, which is harder to define and achieve. An importantresult is also that the dialogue in the interpretation process has been found to be acatalyst for new research findings and of increased knowledge..

The object under investigation in this Master?s thesis is students? information use in connection to Bachelor thesis writing. The purpose of the study is to increase understanding of why nursing students and product engineering design students are using information in such different ways despite their comparable starting point. The empirical material consists of 18 student theses and a document comprising directives for thesis writing that are analysed from three different theoretical perspectives. A citation analysis of all 18 theses is carried out.

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 aim of this essay is to analyze how media constructs strategic positional statements in debates of great immediate interest in order to stress ideological standpoints. Two questions are derived on the basis of this aim.- How is Russia positioned in Svenska Dagbladet's and Dagens Nyheter's editorials in the debate on the Swedish defence during 09-01-13 - 09-01-31?- Are there differences in the positional statements between the newspapers?In the study a Critical Discourse Analytical (CDA) approach is applied, and more specifically that of Teun A. van Dijk. Both the theoretical basis and the methodological tools are based on van Dijks CDA.

The purpose of this study is from a case study develop a model that aims to cost effectively improve productivity in a manufacturing production process. The study highlights the importance of having knowledge about customer needs and using a holistic process perspective when improving productivity to identify the relations between the process stations and by this find problems that cause waste and losses in productivity. Tools and methods used to make production more efficient such as single minute exchange of die, spaghetti diagram, 5s and master production schedule is presented an applied in the model to see how these effect costs, productivity etc.Maintenance effects on quality and productivity in a manufacturing company will as well be covered in this thesis. The results and conclusions finally reveals how the process improvement tools, maintenance and production planning for example effects each other and why it is important to establish an attitude in the company where continuous process improvement should be emphasized..

We are living in a society where the digital technology is a tool that integrates into our life and changes our daily life and the way we communicate. The easy access to information and the opportunity to communication change the schools organization and demands new ways of teaching with and in contact with the surrounding world. That is why it is interesting to know how teachers can create an education environment with support of digital tools that fulfills a meaning for themselves, the pupils and the goals of the curriculum. This study is about how six teachers in one elementary school creates an education environment with support of digital tools and how they think the affect the pupils cooperation, communication and participation.The theoretical frame for this study is built in a sociocultural perspective, where people learn and develop through participation in social practices. To get the understanding of how teachers are thinking about the challenges and possibilities that digital tools have in the education environment, I choose a qualitative research method.

In Sweden whenever trains or maintenance workers want access to the railway system, their requests of usage and movements are being supervised, granted and handled by train dispatchers. The profession holds a key role in making the complex railway system work in terms of efficiency, safety and delivering on-time arrivals. This master thesis, delegated by the Swedish Transport Administration, has been carried out at the Division of Human Computer Interaction at Uppsala University and at the train traffic control center in Gävle. The aim has been to map what information the train dispatchers use in order to make safety-related decisions concerning their working goals. And further to describe and analyze how the train dispatchers, visavi their tools and systems in the work domain, gather necessary information.The result indicates a complex, diverse and spread out setting of different programs, procedures and tools that make satisfactory fulfilment of efficiency, safety and punctuality in relation to the time table hard.

The purpose of this thesis was to find out what experiences teachers have from using a class blog in teaching. What are the advantages and disadvantages by the use of blogs in education?I have used qualitative interviews with four teachers in grades 1 to 6 who have worked with a class blog in teaching between one and three years.The study has shown that teachers' experience is that the blog serves as motivation and promotes learning for many different pupils and that, together with other digital tools is more equal. The main benefits that teacher mention is the expanded concept of text that offers multiple forms of expression and the authentic reader, which makes it more real, important and meaningful. Other benefits that come up are that it helps students to see their learning and learn from and with each other.

The purpose of this essay is to analyse the movie Hotel Rwanda from a didactic point of view using the movie?s use of history and historical culture as the main analytical tools. We also intend to problematize the use of movies in teaching focusing on the teaching guide from the Swedish film institution concerning Hotel Rwanda. We choose to work with a qualitative method. The reason why we decided to work with a qualitative method is the intention, as mentioned before, to analyse the movie using the tools we described earlier.
