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.

Abstract Over the years the consciousness of risk has grown. It?s hard to influence risks, therefore there are guidelines stating that significant risk must be included in the annual report. This paper is a case study; the purpose was to examine how four Swedish listed companies chose to disclose their internal and external risks. Risk is initially described in general sense and then it figures to what constitutes an economic risk.Through a case study of four Swedish listed companies? annual reports we have, through qualitative methods found how the companies chose to disclosure their risks.

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

Legionella can be prevented, the question is how. This report is a degree in construction engineering education at Chalmers University in Gothenburg. A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.

Toothbrushing is the best available method in remaining or restore dental health in dogs. This report treats different aspects about toothbrushing and other dental home care treatments in dogs. Questions like why the dog?s teeth should be brushed, what effects toothbrushing have on dental health and how the teeth can be brushed are treated. Furthermore complements to toothbrushing are treated, the options and their effects.

The purpose with this report is to give structure to the storage area betweenproduction and packaging at Spaljisten AB in Åseda. The purpose is also to givesuggestions for improvements of work tasks and thereby simplify and improve thematerial handling at the packing process.The background of the task is that Spaljisten AB is going to increase theirproduction and thereby they also need to increase the packing rate of theirproducts. They will manage this by installing a new automated packing line andincrease the efficiency of the old manual one. The theoretical background ismostly obtained from literature which contains relevant facts for our report.The storage area has been studied visually in order to search for improvements oftoday?s layout.

This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.

Background and Introduction: Environmental report drew attention in the 1980s when the Va?rldskommissionen fo?r miljo? och utveckling received a mandate from the FN to investigate the relationship between economic development and environmental degradation. In connection with this, although sustainability a new item for many businesses. But to say exactly what sustainability is all about is very difficult. In 1996 the then Government Redovisningskommissionen a study on the introduction of an amendment to the Annual Accounts Act, which would force companies to report on environmental issues in their annual or consolidated accounts.

Abstract This paper focuses on whether individual development plans as well as action programmes are needed.Pupils in need of particular support get to be involved in an action programme ? the school needs to provide any particular support a pupil needs. However, the individual development plan does not substitute the action programme. Thus an action programme as well as an individual development plan will be provided to students in need of particular support.The individual development plan follows the pupil throughout the entire education, regardless of whether its content changes, whilst the action programme pertains to a limited period of time. Pupils that are not in need of particular support are not likely to need to set goals for themselves in addition to those already set outside of school.

Värnamo Elnät owns and operates a ripple control system which is used to control loadsespecially when the grid is heavily loaded and for control of street lighting. This report aims atclarifying technical and economic aspects of the ripple control system?s future. The system wasinstalled from 1975 and onwards and its use was greater in those days when the controllableloads where greater then today, the current controllable load level is about 3 MW. The reporthighlights three different aspects of the ripple control system?s future ? retain the currentsystem, reinvest in a newer system or discontinue the system.In the report the author also discusses relevant connections to Smart Grids and future meteringsystems and tariffs.

The tourism industry in EU is one of the biggest sectors and employs about20 million people. A key factor of the industry is information, much oftourist information is today on the Internet. On Internet there is twoways information can flow, the information can either be pushed to aconsumer or the consumer of the Information can pull it from a source.In a feasibility study for the report the participants expressed thatthey thought the tourist information on the Internet was unpersonal anddidnt fill their informationneeds. The purpose of the report was to findout how push and pull of touristinformation can be balanced on Internet.The empirical data was collected with a feasibility study, a survey anda case. The survey was conducted at IT-University and School of Business,Economics and Law at Göteborg.
