The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

How schools handles threat and violence among pupils could have an effect on the surrounding world, since schools reflect society at large. This study attempts to explore how this is handled within two schools, one secondary school and one upper secondary school. How do the schools work with violence and threats amongst pupils? Who is responsible for what? Is this work based on school guidelines? Why/why not? The theoretical starting-points have been Lundquists implementation-based control-model and an organizational point-of-view using theories about open and closed systems, primarily Meyer and Rowans neo-institutionalism. To gain validity, the study has been carried out by way of triangulation, i.e.

The purpose of this study is to examine the situation of the school for boys 15-21 years of age lacking compulsory school attendance and is being located at five residential care units from the pedagogues? point of view. The study was conducted by interviewing four pedagogical leaders and two teachers. The results demonstrate that the boys can choose the subjects they study as well as the amount of time they spend on studying each week. The teachers include non-learning activities during their lessons.

This study investigates whether teachers working with children ages 6 ? 9 are including an LGBTQ perspective in their teaching methods. The purpose is to critically examine sexuality and gender as part of the teaching methods in Swedish schools; whether teachers are working with LGBTQ questions in their classes, and if so, how. The following research questions are answered: Are the teachers incorporating an LGBTQ perspective in their classes, and if so, in what sense?Are LGBTQ questions relevant and of interest in the education?Do teachers feel like they have gained the right tools in their pedagogical education and/or in their workplace to work with LGBTQ questions in their class room? And if so, in what way? The method used is qualitative research in the form of interviews and observations.

The purpose of this paper has been to shed light on the ways the history represented at the City Museum of Stockholm can be used in education at the Gymnasia level. I have made use of the following set of questions to attain this purpose: 1) How is the City Museum's activity vis-á-vis the gymnasia organized and what is the purpose of this activity? 2) What positive results do the interviewees see in the collaboration between the schools and the Museum? 3) Why did the teachers represented in this paper choose to make use of the Museum in their education? The bulk of the study is based upon three interviews with the First Curator at the City Museum of Stockholm and two teachers, from Viola Gymnasiet and Skogsgårds Gymnasiet respectively. My method is qualitative and interpretative with hermeneutic features.In my interpretation of the source material I have made use of historian Klas-Göran Karlsson's classifications regarding the needs for various forms of history, use of history, users and functions of results. In this way I have been able to establish how the Museum and the teachers represented in the study make use of the history that is represented at the Museum.

This article elucidates the professional dialogue between student teacher and supervisor and it´s conditions as a supervising method in professional academic education. The aim of the study is to discuss how students articulate the conditions of the professional dialogue and the positioning of themselves and supervisors are made. The student taped discussions were analysed. Inspired by positioning theory we analysed the students discussions in order to interpret and elevate patterns showing the conditions concerning the professional dialogues for the students teacher education. The main findings are the students positioning themselves as listener and the supervisor is positioned as communicator of rights, obligations and oughtness.

Starting point to this Paper is the idea and wish to adapt the society and its different activities to a recycle society. A building area in Göteborg is planned and investigated for such adaptation. In the district named Skogaberg, about 130 households totally are planned from what 20 are blocks of flats. The idea with this project is to constitute an alternative sewage system, a Blackwater system, were the fractions of most nutrients and least pollution are separated, taken care of and utilised. The aim is to get a market and use the nutrients of the organic waste from the household in agriculture use.

Type 2 diabetes is a growing disease in the population which includes that older people are a risk group. With the disease grows even cost?s. A lifestyle change is a major part of the treatment for type 2 diabetes. There are several factors that suggest positive effects on prevention among the elderly where, among other things, economic and health benefits are presented.

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

In this study a case study was conducted at the Transport Agency. The government agency is seeking better alternatives to its current ways of keeping track of important dates stated in legal documents. The agency wants to explore the possibility for an IT-solution for keeping track on those dates. In the case study change analysis was conducted on the vehicle type approval process. Qualitative interviews were conducted with a section manager, vehicle type and component approvers, and with a system administrator and a system manager at the Transport Agency in Borlänge.

Abstract In the contemporary world of information technology you find a multitude of applications and systems covering a broad spectrum of areas of need in different companies. One effect of this multitude of programs is the difficulty to make them exchange information with each other or to collaborate, since they are developed by different programming languages for different platforms, with different standards and different data formats. Our aim with this work is to describe how it is possible to tie these programs together to make them actually communicate with each other in order to exchange information, share their native methods and also to become a part of the overall business processes. In this integration task you will, among other things, find different levels of application integration such as data level, method level, application interface level and user interface level integration. Application integration also involves hardware components, called middleware, that facilitate the physical connection between applications. There is a range of different middleware products offered today on the market.

The way towards an equal society, where both women and men has the same possibilities both private and in professional life, has been a long and still ongoing process. During my practical studies to become a recreation instructor I have noticed a difference between the children I have met in my workplace. What I saw was that girls and boys had a different approach towards their future, plus that the pedagogues at the school had different roles depending if they were men or women.In this study I have investigated which dreams and visions a group of after-school children has, plus how these distinguish between the genders. I have through group interviews, first three boys and then three girls, investigated how children look at their future focusing on career, spare time and familysituation. The questions have also focused on how children look at the schools pedagogues with gender as a premiss.My result shows that the children's vision on their future tends to look different between the genders.
