Statusbedömning av asynkronmotorer
Induction motors, often referred to as the workhorse of the industry, play an important role in production today. Therefore, it's important to diagnose any faulty induction motor prior to failure to avoid costly and time consuming production stops.This thesis compares methods for diagnosing induction motors in operation, MCSA, Park's vector approach and the standard method used by Swedish industries today. By simulating broken rotor bars and short-circuit in one of the windings, each method is tested and the results are compared using matlab.The results need further verification due to uncertainties of the condition of the test motor, even though the experiment gives a hint of the different advantages of each method. A combination of the methods should be able to tell if the motor needs further examination..
Att finna bilden - varför indexera bilder efter innehåll och hur bedömer man en bild?
Computerized methods for searching pictures are becoming more common. With these it ispossible to make powerful search requests using a combination of terms and search oncomprehensive descriptions of the pictures. The descriptions can encompass various aspectsof the content and allow different interpretations and levels of detail.This essay is about how you can examine and describe the content of a picture from manypoints of view. We have tried to identify differences in searching behaviour, and studiedsome methods for indexing of pictures. Our concepts are taken from the philosophy of artand from theories about the meaning of languages.In the future perhaps libraries can make pictures and illustrations in books available to thepublic, in a sophisticated system, for the purpose of providing visual documentation forstudy, research or other kinds of exploitation..
Bilder av Trotskij
My aim in this case study has been to create a method for creature design to test this method in a production and evaluate the results. To achieve this I studied and analyzed the methods of three concept artists and illustrators named James Gurney, Neville Page and Iain McCaig. From the analysis of these artist´s methods, combined with my own personal experience, a new method was formed. To test this method a creature was designed based on directives given by a game design group in the process of creating a table top role playing game in a fictitious world. These directives where given for the creature´s role and its living conditions.
Leder icke användarcentrerad systemutveckling till låg användbarhet?
Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.
Matematikundervisning i Waldorfskola respektive kommunal skola : En kvalitativ undersökning av två olika grundskolor
The purpose of this study has been to compare teachers' differing methods of teaching mathematics and their perspectives on the learning process in a municipal school to a Waldorf school. The study has examined which approach best promotes student engagement and learning in mathematics in the first three years of schooling. The study is based on four interviews. The informants? accounts are interpreted using theories from previous research.
Att upprätthålla krisberedskap : En studie av E.ONs krisorganisation
The purpose of this paper is to investigate how organisations can keep their crisis preparedness alert although crises do not occur often. A crisis organisation will lay dormant within a larger organisation for long periods of time. This may cause a problem when a crisis does occur if the preparedness has not been kept alive.From previous researchers that we have studied within this field we have identified two distinct methods to do this. The first focuses on the importance of detailed crisis plans, while the other method suggests that it is more essential to develop specific competencies with the employees. We also find that keeping knowledge within an organisation is a matter of organisational learning and memory which we therefore discuss and analyse.We have performed an interview study at E.ON in Örebro, and we have also had the opportunity to read E.ON?s crisis plan.
Införande av evidensbaserade metoder: ett kommunperspektiv
This thesis is composed within the framework of the supplementary course in psychotherapy concentrating on family therapy (60 credits) arranged by Lund University's affiliate in Västerås, Sweden.The purpose of this thesis has been to explore how the idea to initiate evidence based methods in the workings of the Individual and Family Care Department of the City of Västerås was born. Furthermore the thesis will explore if consideration for methods of theoretical implementation are implied. The study assumes a qualitative attempt and is based on semi-structured interviews from three levels within the organization, including both management and operation.Theories on organization,implementation and the theory on change strategies have been used as a theoretical starting point.The study result shows that introduction of evidence based methods in the City of Västerås is based on the experiences of the organization regarding the need to develop and increase social services contributions to non-institutional care. Experiences from expensive transferrals to institutions which only occasionally produced satisfactory results were a contributing factor. New published research and a strong interest and desire inside the department to improve and change social services contributions have naturally been a positive influence for the development.
Forskningsområdet biblioteks- och informationsvetenskap vid Högskolan i Borås ? En bibliometrisk studie av den intellektuella basen 2001?2006
The aim of this study was to map the intellectual base at the Swedish School of Library and Information Science (SSLIS) at the University Collage of Borås, and to compare this intellectual base to the intellectual base of the research area Library and Information Science. This was done by analysing the citations in publications published, between the year of 2001 to the first quarter of 2006, by researchers at the institution, using the technique of author cocitation analysis. Cluster analysis and multidimensional scaling, statistical techniques that are traditional i the author cocitation analysis, formed an objective map of the intellectual base at the SSLIS. This map was then compared with three prior studies, that used the same technique to map the intellectual base of the research area. The result shows that the map of the intellectual base at the SSLIS consists of the specialities: user studies, library studies, culture/cultural policy, information retrieval, bibliometrics and information in organisations.
Krishantering : Granskning av krisarbete i grundskolan
My purpose in this paper is to study teachers' work in reading and writing in primary school and special school. I want to find out if they use the same methods, strategies and materials to help students learn to read and write. I will find out the answer to my purpose by performing two qualitative observation and two qualitative interviews. Lundberg (2010) is the researcher I relate to during my study. Through observation, I see how teachers work with students in the classroom during a lesson in the Swedish language. During the interviews, I received answers to how teachers work with language, the materials, methods and strategies they use. I found out that teachers use specific strategies when they help their students. They use a work material that is tailored to curriculum in Swedish language and it is based on the phonics method. .
Individen kommer inte långt själv för ensam är man ingenting : En studie om arbetsmiljöns påverkan på hälsan
The purpose of this thesis is to achieve a greater understanding of how the social workers at the family unit in one of Stockholm municipalities comprehend the work environment at the workplace. Our aim is also to find out how the work environment can affect the health of the social workers in the form of their wellbeing and comfort at the workplace. In order to answer our purpose we conducted interviews of all social workers at the family unit in one of Stockholm municipalities that describe how they experience the work-environment in the workplace and how it influences their health. We have analyzed the interview material in a thematic analysis based on three theoretical perspectives; SOC, claim ? control - support and Human relations. We have also coupled the interview material to the background chapter in this thesis that describes how a good working environment should be structured. The chosen method characterizes an abductive process.

Om individanpassad matematikundervisning i praktiken : en intervjustudie med tre pedagoger i grundskolans tidigare år
Studies show that the performance of Swedish students in the subject of mathematics is to be considered somewhat average. The government has therefore decided to assist with extended project funding to schools on a local level in order to improve these results.Schools will, unlike before, practice teaching suited for the individual needs of students based on their previous experiences, knowledge level, language comprehension and their environment. This is also clearly stated in the Swedish school curriculum.My survey shows how three teachers in primary school actually work towards individualized teaching of mathematics and what methods they prefer. This survey also answered what these teachers considered to be the obstacles and opportunities with individualized teaching methods. The difference in approach of how to practice this has also been documented.The survey, based on interviews and class observations, have been analyzed and compared to previous research and theories in the field of teaching practices.

Undervisningsmetodens påverkan på skolbiblioteksanvändningen: exemplet problemorienterad undervisningsmetod
This thesis is an attempt to study whether if problem-oriented teaching implies a moreadvanced use of school libraries than other teaching methods.Teachers have been interviewed about what kind of information they and their pupils need,and where they find their information. Another question is whether the problem-orientedteaching method makes it easier for the pupils to find information in school libraries thanother teaching methods do.The result of the study is that a problem-oriented teaching method creates opportunitiesfor the school library to become an important place for information retrieval. This teachingmethod is a major, but not the only determinal factor. Other contributing factors could beteamwork between teachers and school librarians and the existence of learning aids..
