In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

The purpose of my study is to investigate teacher?s perceptions of their mission in the preschool class, and how they work to promote children?s written language development. What methods and working methods they use to awaken curiosity and motivate children to read and write. I am using the qualitative research method to get answers to my questions. I have made four qualitative interviews with four teachers in preschool classes from different schools.My questions are:What conceptions does teachers have about their mission in a preschool class?What different methods and approaches does teachers use to stimulate and wake children?s curiosity for reading and writing development?The theoretical basis for my study is the socio-cultural perspective, where learning occurs in interaction.

AbstractThis report has been developed in cooperation with Peab Region Bostad Göteborg, mentor at Krook& Tjäder (through Chalmers), and examiner at Chalmers University of Technology. The report is the result of a research of a building project, constructed by Peab. The report is investigating and it means to identify and evaluate qualities in the dwelling and its surroundings. Its purpose is to evaluate how the residents in a chosen housing cooperative enjoy living there. It shall, with help of chosen quality aspects, identify what expectations the residents had before moving in, how they experience the dwelling and its surroundings today, and what hopes they have for the future planning of the area.

Our premiss in this study is the escalating competition in the swedish newspaper market, which have become an issue regarding smaller editions for the newspapers, and some scientist have claimed that this has brought an sensational touch to their news. With this in mind, we have studied if a sensational touch is brought to the two biggest Swedish newspapersAftonbladet?s and Expressen?s first pages. Our purpose with the study is to look into the newspapers development regarding a more sensational newsworthiness on the front page over time. The use of quotes, images and news themes is indicators to measure the development.Trough a content analysis from three different years, 1972, 1992 and 2012 we have measured the data with the computer program SPSS.

In subsequent to Post-colonialism the African nations have dilated into different political directions. While some nations have established well-functioning democracies, others are still under authoritarian regimes. The aim of this thesis is to examine if civil society has an impact on democratic development in West Africa. Therefore the theoretical starting point is Putnam?s theory of social capital, but this study will also examine other possible causal explanations for democratic transition.This study will be based on a comparative analysis of Ghana and Guinea.

The actual project presents the development of a testing rig for a steam engine. A short overviewabout the development of steam engines is presented, until arriving to the development of thepresent engine, which will require to be tested in different ways.The testing rig studied on this project (based on a Lanchester engine) will be used to testdifferent materials and layouts for the group Piston-Cylinder.The engine is a high performance steam power engine, which is going to have a highpower/dimensions ratio, what will lead to require high performance components and materials.An introduction to the testing rig is presented, and the entire design project is done in order toreplace the disappeared documentation of the current testing rig, built on the 1970?s. Also somemodifications done in the original testing rig are presented, as well as some detected problemsand their possible solutions..

The purpose of this examination paper is to get an understanding as an upcoming teacher about how friends make an important impact on children?s identity development in school, their choice of friends circle and what kind of groups there can occur among them. With a deeper comprehension of these circumstances should an educationalist be more considerate and adapt his or hers education to prevent negative group formations and to be an outsider. To achieve my results I used a qualitative research method where I through observation handpicked eight students from upper level of compulsory school with different friend circles from two classes for further interviews. Beside this I observed students in their school environment for three days.

This work of examination describes an environmentally oriented product development aimed to develop new packaging with improved environmental and sale aspects of the products from Primus Sweden AB. The report covers the design process from the first collection of facts to the final results with a description of all methods involved in the work. The focus has been on a clear environmental awareness and the report contains a deepening of the concept life cycle assessment (LCA) for product development. In the process, the consumers? opinions of the brand Primus and environmental profiling formed the basis for the packaging to communicate the right values such as quality, technology, environmental awareness and adventurer?s first choice.The deepening of the life cycle analysis shows that composting and other alternative treatment of the biological cycle is not possible to implement in a satisfactory way in the design process.The work results in two final concepts.

This study aims to illustrate the Leader approach and analyze the work of collaboration development within Leader. The idea has also been to describe some of the difficulties that might be encountered in this type of development work. By highlighting the strengths and weaknesses of this approach we hope to enhance the chance that future work in similar projects can be implemented more easily. Leader is a tool and methodology used in the European Union (EU) for work on sustainable rural development and it has been used since 1991. The purpose of Leader is that by supporting rural projects they will gain social capital and development in the rural communities.

This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen. .

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.

This Master?s thesis is one of two parts of a combined project called Sustainable development around the Lake Victoria, the purpose of which is to investigate the importance of local anchoring and active participation in the work towards sustainable development. The present study aims to investigate whether men and women are empowered by the participatory rural appraisal (PRA) process promoted in their villages by the VI Agroforestry Project Masaka/Rakai. The study is primarily based on interviews with farmers within the project area and brings up a local perspective on the concepts sustainable development, active participation and empowerment. The study shows that to improve the farmers? livelihood and to create a sustainable development in the community, the farmers have to be actively involved in, and in control of, the process.
