Urban densification as a planning strategy is of interest in the planning context of today. It is also seen as a part of the sustainable development. Urban densification as a concept is commonly used in the discussion of a sustainable development. Thus, the question about urban densification is an important challenge in the current planning context. A deeper understanding of the process which urban densification has developed from is necessary, since planners then will be more able to manage this challenge.

This master thesis has been performed at Vattenfall Power Consultant in Gothenburg and Trollhättan for Vattenfall Vattenkraft. In this report vacuum circuit breaker in small-scale hydropower stations with the rated power 4 MVA and below has been studied. Models of the stations are modeled and analyzed in PSCAD/EMTDC to study the high voltage transients that are created after current chopping with vacuum circuit breaker. Vacuum circuit breaker may chop the current before it reaches zero value, which means that high voltage transients can be created. The equipment of the stations can be destroyed by high voltage transients.The purpose of this thesis is to examine the use of vacuum circuit breaker in small-scale hydropower stations and the risk for high voltage transients from current chopping.According to the results there is a risk of high voltage transients after current chopping with small synchronous generators in stations with the operating voltages 0.4 kV and 3.6 kV.

Sarah Kane?s first play Blasted (1995) has often been read in a normative and biographical way by critics, authors and previous researchers. This essay makes a supplementary close reading of Blasted from gender and genealogical perspectives and utilizes theoretical works by Judith Butler, Luce Irigaray and Michel Foucault. My study makes clear that the characters different positions in language and talk create and maintain a power imbalance between them. Efforts to change and develop one?s individual position in language and talk are being made throughout the play since it is the only way to bring about a change in the social power structure.

This essay?s focus lies on the collaboration that takes place in hospitals and called a care-plan (vårdplanering) between the two organisations: Health-care (landsting) and social-care (kommun). According to the Swedish-law are these organizations responsible for the care of elderly individuals in Sweden. The aim of this essay has been to study closely this collaboration in order to see which partner has the most influencing power.This essay is of a qualitative character, which means that the results that are presented are based on six individual interviews with employees from the two organizations. The employees chosen for this essay all have job experiences from the collaboration that takes place during care-plans in hospitals.One of the main results of this essay has been that the two organizations are not equal collaboration-partners.

AbstractThe background to this essay is previous experience in working in a preschool abroad. The teachers I met there did not relate to the children in the same way that I?m used to in Sweden. In my view, different expectations on the children, made them not make use of the children?s full potential to develop.The starting-point for this essay is the?life world perspective?.

In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.

Sweden introduced a development assistance policy in 1952 and thirteen years later Sida, Swedish International Development Cooperation Agency started, in 1965. But in 1995, five separate development assistance authorities came together and established the new Sida as it is today. Sida is Sweden?s representative in the development assistance policy field and they work through projects that have to be presented through a Country Strategy Process (CSP). The aim of this paper is to point out Sida?s perspective on the conducted development assistance policy and what guide lines that are followed.

ICT and digital artifacts is an important resource in the society, especially in schools. That is why we have chosen to study if and how teachers uses ICT and other digital technology in their education in the history subject. We think that both subjects are important because history is a subject that has to do with the past, the present and the future.We made qualitative interviews with seven teachers from three different schools. We have analyzed if the teachers sees ICT as a burden or a resource in their education and also in which extend they have digital literacy. We have chosen to discuss different authors view on ICT in the education and digital literacy.

This paper is intended to provide a picture of which associations water can wake in the human mind from the perspectives of garden history as well as from that of environmental psychology. I hope to paint a fairly broad picture of our perception of water that can serve as a basis for discussion and as a starting point for different forms of design work in landscape architecture. The historical perspective emphasizes the importance of water as a condition for the emergence of gardens and in a wider perspective the importance of water in early cultures. Also, I describe a picture of how water has been used throughout the history of gardens from early Egypt to the baroque era. The garden history analyzed from an art historical perspective gives a picture of human associations to water, and the history behind these associations is presented. As a compliment to the art history approach, I have chosen to highlight our associations with water from the perspectives of environmental psychology and evolutionary science.

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

Följande studie undersöker i vilken utsträckning parterna i trepartsförhållandet Upsala Nya Tidning, annonsör och läsare har överensstämmande åsikter om vad som är viktigt i relationen, samt hur väl de känner till varandras uppfattningar. Vi väljer att studera förhållandet ur ett trepartsperspektiv då de mer traditionella tvåpartsförhållandena inte är tillräckliga för att beskriva den komplexa verkligheten. Studien utgår från UNT:s printupplaga, men skildrar även skillnader mellan den och webbupplagan. Ett representativt urval av varje part tillfrågades via en enkätundersökning vad de själva tycker är viktigt och vad de uppfattar är viktigt för övriga parter. Resultatet visar på att parterna inte har överensstämmande åsikter om vad som är betydelsefullt i relationen.

This study is about different teacher?s ´conception of remedial classes and its function in Today´s School. ?A school for everyone? the utopia that all schools and teachers aspire for. All pupils, regardless of ethnic background, class, and religious affiliation should be able to go to school without being segregated and are seen as different.

The purpose of this project is to examine the development of the upper secondary school physics course and from this get a better understanding why the course is organized the way it is today. The timeless argument for studying science in school will begin this essay. After that the reader will be aware of when important discoveries in physics were made. Then school history is presented. In this part we are told when the first school started in Sweden, but the focus lies on the upper secondary school and the physics course.

The purpose of this thesis is to see how film can be used to invigorate children?s language development. There is not much research regarding this, which is why we have chosen to study this particular topic. The study consists of questionnaires, an interview and a pilot study. We have chosen to proceed from a socio-cultural perspective, language perspective and learning perspective, thus we are interested in the teacher?s views and thoughts about film as a learning tool complemented by what children can gain through film.
