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.

This paper examines the reasons behind firms considering backsourcing. While firms experience problems with their outsourcing activities, backsourcing emerges as an alternative solution. Firms primarily take cost considerations into account when reconsidering their outsourcing practices, but this only scratches the surface. A deeper analysis is needed, since cost increases arise from issues such as quality defects and cooperation problems. Even though production costs are low, outsourcing always implies transaction costs.

The objective of this thesis was to get more knowledge about how to design a dairy farm reducing the working hours and the work tasks whit high work load. I will try to reduce the working hours and the tasks whit high work load on my own farm witch I am about inherit. Today, the old stanchion barn has room for about 60 cows and 74 young cattle and need two men to run it every day. The total acre is 188 hectare, 100 hectare forest, 65 hectare farmlands and 23 hectare natural pasture. I have studied two solutions. In the first solution, I will use my old barn for young cattle and build a new barn for the cows.

The purpose of this study is to identify how the needs, demands and preferences for a certain service appear among University students in Kalmar. This is necessary to examine in order to create and design a possible service that will solve the problem with the University students eating habits.This study is based on a qualitative method with quantitative elements. The qualitative method contains of three focus group discussions. The quantitative method contains of a questionnaire. All respondents in this study fits in the target group.One important conclusion that we have stated after the investigation of this study, is that the nature of this problem seems to differ from person to person.

The aim of this research is to do a comparison between students? view of equality in secondary school and in gymnasium. The research begins with four focus groups, two on each grade to conduct material. The focus groups with girls and boys were separated from each other. With help from the researcher, acting as a moderator in the focus groups, the students have discussed advertisement and what message it convey.

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used. The most common standard in Europe is EDIFACT, but with increased interest of using the Internet for business communication there is a need for a standard that is adjusted for use over the Internet.

ABSTRACTThis project thesis has been written at the request of Mälardalens University, Västerås.The aeronautical engineering students at Mälardalens University and the pupils of Hässlö upper secondary school, all gets the opportunity to perform a computation lab with a real turbojet engine during their study. The goal of the lab from the University is that it should give the students applied experience from the theory part of which has been tought in the course ?Aircraft Engine Technology?.                      The pupils of the Hässlö upper secondary school are performing simpler calculations from the measured values of the equipment. This turbojet engine is located at Hässlö airport in the premises of Hässlö upper seconday school.Since the installation 1989, the engine has lost both thrust and reliability. This makes the theoretical computations made by the students inaccurate.

This bachelor thesis consists of an analysis of museum environment. In the research, case studies have been done at the, Stockholm based museums, Swedish museum of Natural history?s exhibition Natur i Sverige (Nature in Sweden) and the Nordiska museet?s (Nordic history) exhibition Modemakt (Power of fashion) and learning environment Lekstugan (playhouse). The purpose of the research was to study how cultural heritage is used and developed within the museum pedagogy aimed at children. The research is based on a multimodal approach with focus on learning resources.The research examines the museums focus on children and youngsters, what the goals for this focus looks like on respective museum and how the focus is visible in the actual museums.

This thesis describes teh solution of two problems regarding safety on powered lawnmowers; protectning the users from injury when using the lawnmower in slopes, and when cleaning the cutting blade.The task was carried out through initial studies on a representative lawnmower. A generation of ideas followed with an evaluation to select the best solution. The winning concept was further developed to reach acceptable performance. The word resulted in a functioning prototype utilising an original way of detecting inclinations without incorrect signals. It c an serve as a platform for further development into a product.The work gives insightful experience of solving real-world problems, and especially to deal with situations where several variables and their effects are unknownPlease note that several parts of the work are confidential, and have therefore been removed from the thesis..

Sweden is seen as one of the world?s most feminist societies. In January 2009 all grounds of discrimination were merged into a common law; Diskrimineringslagen. This paper examines representations of gender discrimination, linked to feminist perspectives, in the Parliamentary debate on Sweden?s new discrimination legislation through a discourse analysis.

In many products a compromise between ground clearance and the required space to store the product has to be made. This problem attracted the attention of the authors of this thesis.The objective of this project is to develop a functioning solution to a foldable wheel. The solution should be applicable to several types of product groups. A limitation for this work has been made so that the work only covers solutions for lighter vehicles.The purpose is to drive this project forward, so that a solution can be found. Furthermore the purpose of the report is to clarify how the authors proceeded to design and construct the wheel according to a fixed specification.

Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

In this report I have made various comparisons between different client solutions; a standard client solution (PC-server), to use as a comparison and look at various differences in costs against the other client solutions that I have compared, which is Windows Thin PC, Dell Wyse, Red Hat Enterprise Virtualization and FSData terminal server/thin clients. All these solutions require a form of server to work against, which also the standard solution uses, but the main difference is that most of the data and computing power is on the server instead of the client.Window Thin PC, Dell Wyse, Red Hat EV and FSData all use some kind of thin client as hardware. Some of the main differences is that Windows Thin PC can be installed on almost any hardware. Dell Wyse is a special hardware group from Dell, that uses its own proprietary software, and Red Hat EV which is based on linux, is the cheapest option where the only cost is for support. FSData terminal server/thin client use as the name suggest a terminal server and a form of thin client to connect to it, the solution essentially means that your rent the complete hardware from FSData.The comparisons are made with the view of different scenarios based of the number of clients, where costs and licenses, as well as time spent on installation, upgrades, monitoring and managing are some of the main points raised..
