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.

The aim of this essay is to examine how two different schools in Södertälje municipality are working to include and integrate newly arrived high school students in the subject Swedish as a second language. I will do a comparative study in which I study the teachers? completely opposite way of working to integrate newly arrived school students in the subject Swedish as a second language. I have used a qualitative method where I have conducted interviews. My main theory is Peder Haug's (1998) theory.

Densification is one of the urban visions for sustainable development - a vision that has become a part of the solution to the unsustainable sake dilemma. With the dense city land will be saved, energy consumption reduced and social cohesion improved. The dense city is considered to be ecologically, economically and socially sustainable. Applying an urban design concept has thus proven to be problematic. Density has been found to be a complex concept which is far more complicated than measuring how much built surface that needs to be covered. It is also not disputed what different degrees of densification mean and whether densification in itself is sustainable.

The current demanding business environment requires corporations to act fast in finding effective solutions to problems given the myriad of challenges they face (Dyllick & Hockerts, 2001). The challenges include the impact of climate change on business practices, natural resource consumption, chemical pollution, technological change etc. Moreover, the forces of globalization, heightened concerns about the deteriorating quality of the physical environment and increased stakeholder power are also increasingly having a real influence on business practices (Rainey, 2008). Since 1992, the World Business Council for Sustainable Development (WBCSD) has encouraged the adoption of the concept of ecological efficiency (eco-efficiency) to support business efforts aimed at addressing some of these challenges. The aim of eco-efficiency is to reduce the amount of energy and materials used in production processes to achieve economic and environmental benefits (WBCSD, 2000).

Previous research analyzing information and communication effects regarding high-involvement purchases has so far concerned communication length and the use of salient attributes. Studies investigating the effects of communication on a word-level is however limited. For a high-involvement purchase like an apartment the need for information is vital in the customers purchase decision. The main purpose of this study is to investigate whether the communication in the prospectus varies based on sales success. The study connects research in information search, high-involvement purchases, communication length and information vividness.

The aim of the present study is to describe the experiences of high school students as regards the effects of their activities, in and out of lessons, being published on the web. In addition, a further purpose is to acquire knowledge about whether a website could be used as means of increasing the students level of attention, and focus, to their activities in school; and, furthermore, how such a website should be designed to correspond with the students requests.The implemented methods are interviews with students, school administrators and teachers. A survey was conducted covering the student?s personal experiences and opinions. Furthermore, an interface test of the website was performed.

High school students of today frequently come into contact with the English language throughradio and television. Many students even manage to read instruction manuals and understandhow technical devices work, such as, for example, computer games. However, most teachersunderestimate their students? ability and persist in using Swedish to explain how the Englishlanguage works. I have analysed how high school students manage when they take an Englishgrammar test in English.

In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

The research aims at revealing consumers? loyalty to a high involvement product category, connected to a loyalty membership club. Hence, the study aims at explaining similarities and differences between two markets, differently developed in terms of loyalty clubs. The study used IKEA, its loyalty club IKEA FAMILY and women as the company?s main target group, in a case format to study loyalty membership clubs.

The aim of this study is to examine the knowledge and experience of the bad breath among high school students in Kristianstad. A further objective was to measure the amount of VSC (Volatile Sulfur Compounds) among those who perceive themselves to have a bad breath. A questionnaire with 21 closed questions was distributed to 120 high school students from Kristianstad municipality who were between the ages of 17-20. The results of this study revealed that most of the students had good knowledge of halitosis. The majority of all participants thought it was important to smell fresh in the mouth and also experienced most of their breath as very good or good.

 Background: Self-injury can be defined as deliberate harm one's own body without conscious intent to commit suicide. These patients need skilled care. Purpose: Illuminate nursing staff attitudes and treatment of patients with self-injury behaviour for individuals diagnosed with borderline personality disorder. Method: A general literature study has been made. Based on the objective was a literature search in various databases with ten relevant articles were selected and reviewed.

In 1994 the EU directive of packaging waste was adopted. The result was that all EU member states developed different systems to manage packaging waste and recycling. This paper examines the various systems and the factors that affect the level of recycling. This is done by a cross-sectional study between countries. The results of my study suggest that take-back system generates less recycling than other systems, the mandatory deposit system can affect the recycling in a positive way.

This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.

GPS is perhaps the future in agriculture. The next years will show it but the precision becomes only better and better and the number of users becomes only more and more. This work shows experiences from today's users and how the profitability can be improved on a farm with normal plant cultivation. The aim is to show how big the actual advantage can be to have a GPS and how good precision there is with the equipment. John Deere and Trimble are the big producers of GPS equipment to the agriculture.
