An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

This thesis suggest an explanation for is how it is possible to understand that the large arena project in Växjö grew to cost sums of money that initially in the project not would have been an alternative to discuss, how goals changed and how the institutional environment changed the prerequisites of the project. As empirical part of the research, to describe and analyze the project, the municipality?s documentation of the project have been analyzed and semi-structured interviews have been made. Theoretical perspective is taken from the neo-institutionalism in sociology of organizations and change, and theories of the complexity of large projects with major symbolic value and importance. The project starts with the municipality?s investment and cost to be hold back, defined as a necessary condition in order to fulfil an ambitious drive towards new sport arenas.  Eventually the necessary condition was abandoned and the arenas were built with the municipality responsible for the investment, cost and risk in the project.

This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.

Då jag varit ute på praktik har jag sett att elever allt för ofta bara sitter och räknar i läroboken. Vi matematiklärare måste bli bättre på att variera och börja laborera i vår undervisning. Både för att få med eleverna kunskapsmässigt i undervisningen och för att få dem intresserade och engagerade. Jag har därför i mitt examensarbete undersökt om lärare i år 4-6 använder sig utav konkret material i sin matematikundervisning. Mina problemformuleringar var:- Vad använder lärare i år 4-6 för konkreta material i sin matematikundervisning?- Hur gör lärare i år 4-6 för att konkretisera matematikundervisningen?- Varför väljer de som konkretiserar matematikundervisningen att konkretisera?Metoder som jag använt i min undersökning är litteraturstudier och intervjuer.

This essay examines how four archaeology scholars reason about gender. I have used a qualitative method in making this study of their dissertations.  The aim is to obtain a deeper understanding of gender identity in prehistory, gaining a broader appreciation of how this might be expressed through archaeological material. This essay takes its theoretical departure from postprocessual thinking, where gender perspectives, including feminist and queer theories are in focus. The result of this study shows that the scholars have a postprocessual, structuralistic theoretical perspective in common, and that they use stereotypical identity-descriptions.

We were commissioned to do this study by the Red Cross Centre for victims of torture and war (RKC) in Skövde and questions was asked about how it can be to come as a refugee to a new country and start over. The purpose of this study was to search for a deeper knowledge about older immigrants experiences of their integration in the Swedish community. The conception of ?older immigrant? aimed of persons born before 1954 since these persons culturally was the older ones in the patient group at RKC. This study handled both men and women, was categorised in different themes and was analysed from theoretical points about identity and crises.

Previous research has suggested that there is a strong and positive relationship between being an entrepreneur and possessing a high degree of subjective well-being as well as job satisfaction. The big five personality traits have also been argued to be significantly related to both subjective well-being and job satisfaction. Little is however known if personality affects entrepreneurs and regular employees differently. In this paper the impact of personality traits on the cognitive part of subjective well-being as well as job satisfaction are investigated separately among entrepreneurs and regular employees. This is done through OLS-regressions using a Swedish nationally representative survey Employment, Material Resources, and Political Preferences (EMRAPP), where entrepreneurs were oversampled in order to be able to compare entrepreneurs (N = 2483) and regular employees (N = 2642).

Tidigare forskning visar på att en prisvolatilitet existerar på marknaden för återvunnet material och att den många gånger är högre än volatiliteten för dess motsvarande jungfruliga material. Prisvolatilitet på marknaden för återvunnet material verkar vara en av orsakerna till osäkerhet på marknaden vilket i sin tur hämmar investeringar i marknaden, vilket leder till att färre substituerar jungfrulig råvara mot återvunnen råvara. Volatiliteten på återvunnet material kan ses från två olika perspektiv, ett där volatilitet är en orsak av effektiva marknader som styrs av utbud och efterfrågan och ett där volatilitet är en orsak av olika marknadsmisslyckanden. Syftet med denna studie är att mäta förändringen i volatiliteten för återvunnet material, utifrån ett antagande om att volatiliteten minskar över tiden då marknaderna för återvunnet material mognar och blir mer etablerade. Standardavvikelse används som mått för att mäta volatiliteten, där volatiliteten mäts för fem olika material, vilka har olika tidsperioder beroende på material.

On today?s competitive market, it is difficult to achieve profitability trough high prices on manufactured products. Profitability must be obtained through low manufacturing costs, high quality and short lead times. One of the companies on the market is Sandvik Coromant, manufacturer of tools and chips for metal cutting. This master thesis investigates the methods of manufacturing for boring bars at the manufacturing unit GVH4 at Sandvik Coromant in Gimo, Sweden.

This bachelor thesis explores the library collaboration "HelGe-libraries" goals, guidelines and strategies for their resource sharing of library books and digital resources. The questions asked were: What does the resource sharing look like when it comes to media and services? What goals and guidelines do they have for the resource sharing? What common strategies do they have for the resource sharing? What challenges have they encountered with resource sharing and how have they dealt with them?The theoretical framework consists of Jennifer Rowleys theory of innovation strategies for libraries and Rosabeth Moss Kanters theory on the art of alliances. The method used to collect material was interviews and document analysis. Four informants were interviewed.My study concludes that the "HelGe-libraries" has formulated goals for their resource sharing and that the resource sharing is connected to their goals.

Choosing a new plastic material for a container includes several different steps. In this case,the Finnish company Hackman needed a new type of packaging material for theircutlery- and kitchentool series »Hackman tools«. The project was carried out in cooperationwith the design agency Ytterborn & Fuentes, which has Hackman as a client.Several different demands were put on the material in order to fulfill as many of the clientswishes as possible. The most urgent problem with the existing container was the difficultysfor the customer to clearly see the contents in the container. Because of this problemthe customer tried to open the container in the shop.

Scania is constantly trying to improve their product development process, the PD-process.The company, along with others, is optimizing their development process in order to gainadvantage in terms of shorter lead times and larger market shares. For this to happen, a wellorganized process is required.The PD-process is divided into three different phases that are linked together by a hand-overprocedure. Scania Bus has experienced problems that stem from a lack of hand-over routines,and as a result the product development process has been slowed down. This has a number ofconsequences, one of them being the complication of new project initiations.The main purpose of this master thesis was to review the hand-over procedure. Within thestudy the project directive was also to be examined, and a recommendation of how the start ofa new project could be made easier was included.To begin with, a detailed literature study was conducted with the intention of obtaining thebasic theoretical knowledge needed for this study.

Anonymous job applications as a method to further diversity on the labour market is widely discussed. The method aims to promote an equal selection procedure, where the employer can only judge on merits and experience. We are with this study on the other hand interested in seeing how this specific method of employment has been implemented. We have chosen to perform a small qualitative case study, of a limited attempt of this method in the government administration of Kortedala, a district in Gothenburg.Our intrests are to see whether we can, while studying a specific implementation procedure, show that any implementation problems have occurred. Furthermore explaining it by applying our implementation theory, that consists of Lennart Lundquists three criterias for explaining implementation problems experienced from the appliers' standpoint.

Background: Balanced scorecard is a relatively new strategy in analysing activities in a company. To carry out a strategy in an organization a successful implementation is very important. Strategy implementations are unique for each organization and to succeed it has to be formulated and implemented with the individual companies particular conditions as starting- point. A problem is that the implementation sometimes is treated as a small detail in the planning process. This problem depends on how the strategic plans is carried out.

Syftet med denna studie var att undersöka om och i så fall vilka laborativa material som används i samband med additionsalgoritmer med tiotalsövergång. Studien undersöker vidare de laborativa materialens betydelse för elevernas förståelse vid introduktionen av algoritmerna. För att ta reda på detta genomfördes observationer och intervjuer. Resultatet visade på att  laborativa material var vanligt förekommande. Det mest använda laborativa materialet hos de intervjuade lärarna var pengar.
