The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

Swedish law is very keen on the fact that every person should be treated equal when facing the legal system. When it comes to cases concerning children, social workers and judges are expected to strictly obey the rules of the law but at the same time make individual judgements based on the best interest of the child, something that requires a great deal of empathy and knowledge. Is it possible to live up to the maxim about equality and to simultaneously see the individual needs? With so many different parties and angles in the case, how does one manage to make a solid appraisal of the situation that truly serves the best interest of the child?The purpose of this study was to examine the capability within the social services with focus on objectivity. More specifically it's aim was to find out how the social workers and judges see their capability of being objective in the investigations concerning children.

The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers. A big part of the project was also to find combinations of materials for all components in the gearbox, to reduce weight and maintain or improve the performance of the system. Belt drive was of interest to investigate as an alternative solution to the current design that can reduce wear on the system at a performance test performed in the company before the product is released to market.

The purpose of this study was to examine the threats from climate change coverage in the media. The climate threats start to appear more frequently in the media and because of that it is important to examine what the media conveys to the viewers and readers since it may effect how people act when it comes to climate threats. In this study newspaper has been examined, more specifically daily press and evening press. The papers chosen was Aftonbladet and Expressen, which represented evening press, and Dagens Nyheter represented daily press.The method applied was both a quantitative and qualitative text analysis. With the quantitative method variables were formed and tested against the material.

Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

This study focuses on why people not longer want to be a part of a religious communion they have earlier been a part of. To examine this I have made seven interviews with people who have left their previous communions. Together with the methodological and theoretical discussions on discourse analysis, Richard Jenkins discussions on identity and theories concerning the post-modern society, I have made an analysis on how these people consider their previous communions and its members. They refer i.e. to the social control, the ?closed? culture and the non-questioning-culture that constitute the communions and its techniques.

The purpose of this paper is to juxtapose the theories of learning that are reflected in student?s perspectives of the learning log with that of the pedagogical intentions of the curriculum in order to examine the discrepancy between the experienced and the intentional learning objectives. The paper is divided into two sections. The first section is a literature survey on theories related to the learning log and the curriculum. The second part is constituted by three semi-structured group interviews concerning student´s views on the learning log.

In today?s society, people do not solely purchase a product for its promised use. Instead, a brand is purchased and along with that brand comes a variety of associations. The associations of a product?s brand are what contributes to the added value that, according to this study, is what distinguishes a brand?s power.

In this study the book talk is examined as a communicative act with a purpose to convince according to an under-lying intention to promote reading. I follow the book talk?s way from an idea of the book talker (and the library) to the reception of the audience, with the aim to understand how to talk about books in an engaging manner. More specifically, the rhetorical situation and the purpose of a book talk, the performance and the means to arouse and retain interest in the book talk as a speech and in the books themselves are examined and the impact of the book talk on the audience.The empirical material consists of observations of two different book talks (both directed to children) and interviews with the two different book talking librarians and a few of the children from the audiences to both book talks. The theoretical framework consists of rhetorical theories from both antique and modern times and I perform a rhetorical analysis of both book talks.

The Swedish stock-market gives investors an opportunity to benefit from the global growth while financing companies invests and contributes to a socio-economic development. Parallel to the ownership of the funds also follows a responsibility as companies in the funds affect society and the environment. The growth of savings in funds, combined with an increased focus on sustainability has developed SRI (socially responsible investment). Therefore it is interesting to examine whether responsibility is an exception, which only concerns SRI-funds or a general principle, which includes the whole Swedish stock-market.The results of the survey makes it clear that all the Swedish major banks actively works to integrate sustainability within the respective bank's business to achieve a more sustainable financial system. Thus concludes the investigation that responsible investments are a general principle on the Swedish mutual stock-market.How responsibility is integrated in fund management differ between the banks.

This study aims to visualize the youngest preschool children matematical learning in the free game. In my study the mathematics will be analyzed  based on the interactions children participate in, and how children experience mathematics through the lived body.I have chosen to undertake a qualitative research in form of observations. Through this research method, I would approach the child's perspective, which means that i analyze the material that the children in the observations reveals to me as a researcher.The results of the study show that children experience mathematics skills both through the lived body, as well as in interaction situations between children. The mathematics are around among us, all the time. This is very important to take into account for children's continued development of mathematical knowledge..

The aim with this study was to examine which information sources are used by the librarians in the process of changing automated library system and why. Furthermore it was of interest to examine whether there are any correlations between variables environment, information quality, information availability, information need and information sources. I used a quantitative method that was carried out in form of a nationwide survey. Questionnaires were sent out to all the Swedish libraries that had change library systems sometime between the years 2000.

This thesis has been carried out at the Building and Civil Engineering Programme at Chalmers University of Technology in cooperation with NCC Technology. The study aims to investigate the optimal design of a library of standardized structural solutions for in-house multi-family buildings and what benefits it brings. Today NCC use technology platforms to improve efficiency and simplify the construction process. The platforms provide the constructors guidelines on how construction details should look like, but the details are not complete. NCC Technology started in the spring of 2013 a project to investigate what benefits there are to create a library of standardized structural solutions for the constructors, with more detailed solutions than in the platforms.

Every now and then, in media research studies and in various newspaper articles, schoolboys´ issues reading habits are discussed. Much of what is written concerns boys decreasing marks in the field of literature, in the Swedish language and also their negative attitude towards reading books. Some scholars claim that boys do not read because they consider reading books as a women´s duty. Other people believe that underlying causes for boys negative attitude towards reading is biological, that it´s genetic and consequently physical, and that male and female brains are functionally different. Another theory of today is that boys actually reads, but not that kind of texts and literature that they are exposed to in school.Based on a selection of these opinions and theories, and my own experience and interest for questions concerning school and gender, the aim of this studie was to examine boys worlds of reading.
