Bakhjulsupphängning, fyrhjuling
Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.
CFD simulering av en fyrtakts Otto motorcykel motor
This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

Studiebibliotekarier som pedagogisk resurs på folkbibliotek
The purpose of this thesis was to explore how Swedish librarians working with educational matters In Swedish: studiebibliotekarier experience his/her pedagogic work in the context of a public library. My intention was thus to reach an understanding of how they experienced their educational work. The following questions were asked: 1 How do the librarians experience the physical environment created for their students? 2 How do the librarians experience the co-operation with others involved in their work? 3 How do the librarians experience the formal task that he/she now is given? 4 How do the librarians experience their own pedagogic qualifications regarding the demands that are made upon them by the students? I have interviewed six librarians and incorporated theories on pedagogic roles in an educational context. I reached the conclusion that these librarians believed the environment to be important for the outcome of the students success with their studies.
Etisk utvärdering av chefers ledarskap : Vilka etiska principer bör ligga till grund för utvärdering av chefers beteende?
A reform of higher education in Sweden in 1993 led to stiffer competitive climate among educational institutions. The reform meant that educational institutions now had the opportunity to plan their curriculum autonomously. Prior to the reform educational planning was restricted to the Swedish government. The new rules spelled a greater opportunity for educational institutions to profile themselves based on their educational offerings. The higher degree of competition means that marketing becomes increasingly important when recruiting new students.
Barns delaktighet och inflytande i den pedagogiska dokumentationen i förskolan
The purpose of this study is to find out what the educators idea of educational documentations in ratio to childrens inclusion and impact in pre-school are, together with the child's own perception of the concepts of documentation. We proceeded from the following issues: What are the significance of educational work according to the teachers? What is the teachers idea of a childs impact and inclusion in educational documentation? In what way do the children have influence over, and inclusion in educational documentation? What are the childrens feelings of the documentations? In order to find answers to our questions, we used qualitative examinations consisting of seven educators and seven children from various pre-schools in Stockholm, and thereby, we have analyzed our results. As our theoretical frame, we used ourselves of Vygotskijs and Säljö's sociocultural perspective that is about "progress and learning", which is achieved by interaction and cooperation in a social context. The result shows that the aim of educational documentation is to reveal the childs development and learning, and also to involve the parents by putting up documents on the wall.

Hållbara projekteringsverktyg : Från byggnadsinformationsmodell till simulering ? en utvärdering av Revit och Virtual Environment
This study examines the use of building modeling and energy simulations in the design process of a building. The take-off point is the notion of energy simulations being needed early and throughout the building design process, and that the lack of energy simulations may be explained by the fact that they are time consuming and therefore often too expensive. A greater interoperability between software tools used by relevant disciplines, such as the architect and the energy specialist, would create smoother workflows, which would reduce this cost and open up for more frequent and iterative energy simulation processes. The study is an assessment of the modeling tool Revit and the simulation tool Virtual Environment and whether they can create smoother workflows, and make leeway for a more frequent use of energy simulations throughout the design process. It also investigates the limitations of what can be examined by simulations in Virtual Environment. This will hopefully help clarify the future role of energy simulations in design processes. The method is a trial by error approach of testing the two software tools by building and simulating a model. The results of these tests show that the workflow is not optimal (and therefore time consuming) for frequent and iterative simulations throughout the design process, but it also reveals some great possibilities of what can be performed with these two powerful tools at hand. Further development with regards on platform independency of the building information model, including seamless exporting and importing, seems necessary to strengthen the future role of energy simulations..
Simulering av miljoner grindar med Count Algoritmen
A key part in the development and verification of digital systems is simulation. But hardware simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today?s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster simulators handling millions of gates are needed. We investigate how to create a software gate-level simulator able to simulate a high number of gates fast.

Musik som ett specialpedagogiskt verktyg för barns språkutveckling : Fem sydafrikanska pedagogers syn på musik som pedagogiskt verktyg
The purpose of this essay is to study if and how five South African educators work with music as a special pedagogical tool in children's language development. To achieve the purpose of this study, two research questions were created. As method, interviews of a qualitative character were chosen. The aim of the method is to give the educators the opportunity to think about and use their own experience before answering the questions.The result shows that the South African educators are not using music as a special educational tool. They rather use music as an everyday educational tool to promote children's language development. The result indicates that music in educational activities promotes children?s communication with each other.
Om miljövär(l)den : En kritisk diskursanalytisk studie av miljöetik i styrdokument, förlagsläroböcker och sponsrade läromedel
The urgency of sustanible development is world-over issue. This essay focuses on the relations of enviromental ethics in the context of the Swedish upper secondary school and the subject of geography, by analysing different educational texts.The purpose of this essay is to reveal and identify discourses of enviromental ethics in curriculum documents; Lgr 11 and the plan- and the coursedocuments for the subject of geography, in educational publisher?s textbooks and in sponsored texts related to the subject of geography and finally to discuss potential consequences this might implicate for education. For this have the methodology of Norman Fairclough´s critical discourse theory, CDA, as well as a matrix of environmental ethics, based upon Mikael Stenmarks classifications of enviromental ethics, been used.In the Cirriculum, Lgr 11 and documents for the subject of Geography, and in the educational textbooks from ?Liber? and ?Gleerups?, are the environmental ethics of intergenerational anthropocentrism the dominant.
Fritidspedagoger och pedagogisk kvalitet : En studie om fritidspedagogers syn på pedagogisk kvalitet med stora barngrupper
This work is about leisure educators' views on educational quality in large groups of children. School centers will contribute to children's development and learning through meaningful leisure and leisure educators' contribution with a high educational quality. There are a lot of discussions and writings about growing groups of children. How are the leisure education and its quality affected by increasing children's groups? It sparked my interest and therefore I wanted to examine this more closely how it might look in the leisure activities.The aim of this work was to examine leisure educators' perspective on how the educational quality is affected by large groups of children and what is considered of leisure educators' as a high educational quality.To answer my purpose five interviews was made with leisure educators' in different parts of Sweden and also by studying the theoretical foundations and literature for school centers and leisure education.The results of the interviews reveal, among other things, that leisure educators' feel that the large groups of children affects the quality of teaching at many levels.

Att bli utbildare : En studie av kadetters syn på hur de formas till utbildare
Background: Officers in the Swedish Armed Forces educates their soldiers in various skills and arenas. The Officers get their educational training in officer training courses conducted by the Swedish Armed Forces or the Swedish national defence college. The aim of this study was to find out how the cadets, belive that they are formed into educators, their views on the literature being used in the Swedish armed Forsces, and their views on leadership and educational science.Methods: The data for analysis were collected in spring 2010, by use of a questionnaire among cadets studying the tactical/operational program Ta/Op 07/10 at the Swedish national defence college. The respons rate was 69, 6 %.Results: The majority of the cadets thought that experience was the most important factor in becoming a good educator. Most of the cadets also thought that the literature being used by the Swedish armed forces was good, however, few cadets stated that they will use the material for reflection on their own teaching when working as officers.Conclusions: The Cadets had a positive attitude towards the educational philosphy and literature being used, but few will use the literature in reflecting on themselves as teachers.
