Konstruktion av värmespridare med grafit för flygelektronik
This master thesis was carried out for Saab Avitronics, a business unit of Saab ABactive in electronic systems for military aircrafts. Reliability and weight are of crucialimportance in this environment. To improve reliability and lower the weight graphitemay be used for electronics cooling. Graphite is an anisotropic material and hasthereof high thermal conductivity in two directions (in-plane) and a relatively lowconductivity in the third direction (through thickness).The purpose of this thesis was to investigate if graphite is an adequate thermalconductor to use in PCB carriers. The carriers support and cool the PCB by divertingthe heat dissipation from the PCB components to the edge.
SEMI : Ett projekt med syfte att presentera en ny lösning till katastrofbostäder
AbstractThe number of natural disasters are increasing. Disaster relief today is improving, but not enough.The purpose of my graduation paper is to present a new solution to shelters. It?s important to remember the human, social and environmental aspects when designing a shelter for disaster relief. Each group within the population has to be able to use the shelter and benefit from it.

"Din sökning gav tyvärr inga träffar" : en kvalitativ enkätstudie om användares svårigheter med att söka noter i Statens musikbiblioteks onlinekatalog
The purpose of this Master?s thesis is to study how well the online catalogue of The Music Library of Sweden works when ordinary users are searching for sheet music. The issues studied are: Why do the users fail to find the sheet music they are looking for? Do the users take advantage of the possibilities that the classification codes of the SAB system offer? If not, why?The source material of the study is 144 comments from a user questionnaire about the online catalogue and, in addition, the search log for one day (513 queries). The comments were sorted into seven groups depending on the type of information need, for example searches for certain instrumentation or genres and problems with spelling.
Utvärdering av infästningar i sandwichkonstruktioner för fordonsapplikationer
The automotive industry is increasingly studying lightweight solution in their designs, also rational production and low costs in materials and manufacturing methods are of great interest. This thesis consisted in the practical evaluation of anchors for sandwich panels. The object was to study loads of shearing and pull out of the plane. The experiments were carried out on panels made up of 1mm aluminium coatings and 50mm extruded polystyrene (XPS) at its core. As the fasteners used simple methods such as blind rivets, screw and glue.
Musikalier på bibliotek ? en outnyttjad resurs? En fallstudie
The object of this master thesis is to question why the sheet music heldby libraries is not used more than it is. I have mainly studied the inc idenceof any cooperation between the music schools and libraries,whether there has been consultation on the purchase of sheet musicand whether the music schools borrowed sheet music from the libraries.For the thesis qualitative methods were used in the form of interviewswith ten leaders in music or cultural schools in Sweden. The mainstudy has been focused on the library and music school in Vänersborg.To compare my results and draw conclusions I have used the work ofSanna Taljas: Music, Culture and the Library: an analysis of Discourses.The result of the study showed that there is very little cooperation betweenthe library section for music and the music school. The greatestinterest for cooperation appears to come from the library personnel.Both the library and the music school personnel claim insufficient timeand money for their lack of cooperation..
En precisionsstudie av förstärkt verklighet som positioneringsverktyg
This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.
Experimentella och teoretiska uträkningar för skruv- och bäddhållfasthet för takinfästningar mot stålstomme
Lättelement located in Örnskoldsvik AB is one of Sweden's leading companies in the development of building elements in the form of roofs, walls and floors made ??out of light beams. The company has clients from Lund to Kiruna, and from Norway. This means that the elements have high standards when they have to take many different loads from wind and snow due to such wide geographic variation.The roof elements are structured so that the main body is made of light beams with an I?profile.
Konflikterna mellan IFRS for SMEs och Årsredovisningslagen
Objective: The study will identify where conflicts between SMEs and the Annual ReportsAct exists to find out if there is a need for adaptation of Swedish accounting to achieveinternational comparability.Method: A descriptive method was used to make the regulations in IFRS for SMEs and ÅRLequivalent and to observe the differences between the regulations a comparative method wasused. After this the conflicts could be sorted out with the help of the former so called ?IASinvestigation?.The conflicts and differences then were categorized into the approach theyrelated to, withFrame of reference: The frame for the study is recognition and valuation for collecting andanalysing the data. The approaches are presented for the balance sheet and income statementapproaches as they form the basis for analysis. Annual Reports Act, the EG-directives and theK3-projects are described as they have a central role in the background to the study andfurther understanding of the data.
Rektor - styrdokumentens förlängda arm i arbetet mot ?en skola för alla?
In 2005 we made a research in a Swedish community board about their view on the political and ideological intentions of ?a school for all?. The results from that study were the background to this research.The aim with this research was to find out how principles in the same community were thinking about ? a school for all? and if they were leading a development towards ?a school for all?. In that context they were given the opportunity to explain their definition and reasoning about ?inclusion? and ?integration?.

Plastfilmsöppningar till Tetra Paks förpackningar : En teknisk introduktion och tidig konceptutveckling
This master thesis is an early concept development project about using plastic films and sheets as materials for shaping openings for Tetra Pak packages. It is also a technical introduction highlighting the areas of importance for the development of plastic film and sheets openings. The master thesis has been carried out as a co-operation between Chalmers University of Technology, KTH Royal Institute of Technology and Tetra Pak AB.The master thesis study presents an introduction that gives an understanding of the technical complexities and design possibilities of using thin plastic films and sheets in liquid carton openings. The knowledge is then transferred into five design concepts which points out the areas of opportunity. The technical introduction is widespread and extensive covering current packing trends, the liquid carton package and openings, thermoplastic material properties, and thin film and sheet manufacturing and shaping.
Konstruktion av efterbehandlare
The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.
Mixtekniker
A discussion regarding the alignment and measuring procedure of propeller shafts has arose due to the competing situation in the industry, and higher standards from the customers. An estimation of the deflection of shafts in different alignment situations has been made with help of FEM-analysis and beam theory. This has been analyzed and compared with the experience from Rolls-Royce AB suppliers of shafts. An evaluation of measuring protocols has been made and the result indicates that there is a correlation between the deflection of the shaft and the run out. Results from a measuring test performed by Balino, Spain, verifies this conclusion.
