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.

In this project the task has been to develop a product that will facilitate an operation for personnel working in a sterilization center. The operation is to steer the front of a loading trolley into the chamber of an autoclave, a so-called docking. The moment is complicated because the margins to deviate from ideal docking position and still succeed, is very small.The principal Getinge's desire was that the product could be retrofitted at the customers on their existing systems. One of the Demands was that the product should fit two types of trolleys, one with a adjustable working height and one with a fixed working height. Getinge is supposed to purchase the system from a subcontractor who shall manufacture it and the requirement from Getinge is that the cost of purchase mustn't exceed SEK 500Initially principles, solving the problem was developed.

Today's urban centers become denser, which contributes to higher Demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations we­­­re performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.

Playsam in Kalmar AB are world famous for their design of the toys they sell. Together with their CEO Carl Zedig the goal was to find a new product for the company.  The process has far from been linear, I started off in one direction, got rejected, turned another way and we finally decided to create a rocking horse in a De Stijl style. At the same time taking consideration of the Demands from Playsam and myself.Playsam?s products are archetypes of ordinary objects around us such as the car or the aeroplane. The company mainly produces its toys in wood and the stylized shape together with the blank painted surface has become a hallmark for them.De Stijl, the Dutch art movement containing artists, designers and architects such as Piet Mondrian, Theo van Doesburg and Gerrit Rietveld.

We are living in a society where the digital technology is a tool that integrates into our life and changes our daily life and the way we communicate. The easy access to information and the opportunity to communication change the schools organization and Demands new ways of teaching with and in contact with the surrounding world. That is why it is interesting to know how teachers can create an education environment with support of digital tools that fulfills a meaning for themselves, the pupils and the goals of the curriculum. This study is about how six teachers in one elementary school creates an education environment with support of digital tools and how they think the affect the pupils cooperation, communication and participation.The theoretical frame for this study is built in a sociocultural perspective, where people learn and develop through participation in social practices. To get the understanding of how teachers are thinking about the challenges and possibilities that digital tools have in the education environment, I choose a qualitative research method.

This essay highlights the Swedish retail companies? engagement in ethics and environment issues as a part of the business concept. The Customer is today more aware about what is going on in the world than ever before. Two of the main reasons are the Internet and the globalization. In relation to the customer being more aware about the situation in the world today, the demand for products which have been produced in consideration of ethical and environmental values has increased.

In Sweden whenever trains or maintenance workers want access to the railway system, their requests of usage and movements are being supervised, granted and handled by train dispatchers. The profession holds a key role in making the complex railway system work in terms of efficiency, safety and delivering on-time arrivals. This master thesis, delegated by the Swedish Transport Administration, has been carried out at the Division of Human Computer Interaction at Uppsala University and at the train traffic control center in Gävle. The aim has been to map what information the train dispatchers use in order to make safety-related decisions concerning their working goals. And further to describe and analyze how the train dispatchers, visavi their tools and systems in the work domain, gather necessary information.The result indicates a complex, diverse and spread out setting of different programs, procedures and tools that make satisfactory fulfilment of efficiency, safety and punctuality in relation to the time table hard.

The aim of the study was to examine prerequisites for the changes that are taking place within working with Intimate Partner Violence in Västra Hisingen (a municipal district in Gothenburg, Sweden). My research questions concerned incentives for the new features, their practical consequences and prerequisites for implementation. The study has been performed by three focus group interviews with different parts of the organization represented. The work material has then been analyzed using Implementation Theory, Human Service Organization Theory and theories on breaking up. The study showed that all respondents were motivated to perform the changes, but also that there were significant differences between the groups? conceptions of what implementation Demands, and of the organizational support today.

ABSTRACTIntroduction: Violence towards employees in the psychiatric ward is increasing at an alarming rate. Reports concerning the effect on the staff?s psychological health are disturbing. These workforces are those most affected by brutality and for ages it has been looked upon as a part of the psychiatric line of work. This viciousness is threatening the safety for both the personnel and the patients.

This master thesis was carried out at Scania in Södertälje, Sweden. It investigates the possibility of changing a connector interface that is used when there is a need for splicing the wheel speed sensor and thereby determine the consequences.The problems that exist with the current connector interface occur during assembly, as more time is required to complete a connection in a reliable manner. A complete connection requires joining the male and female connector, insert the connection into a protective retainer and then strap a cable tie on each end of the retainer. This process makes it more time consuming and it requires 20-30 seconds to complete the connection. Solving this problem would save time and enable easier assembly, therefore resulting in economical benefits.This thesis was accomplished through discussions with different sections at Scania, studying available documentations, observations during assembly, writing a requirement specification and contacting suppliers.The aforementioned methods resulted in four connector suggestions, the DT and DTMH connector from Deutsch, MCON connector from TE connectivity and MLK connector from Kostal, each of them compliant with the set Demands of the surrounding environment.

The work that is the basis of this Master Thesis was performed on Scania´s group of cabdevelopment, and concerns the GPS-system in Scania´s trucks. Today, the GPS-systemconsists of an active antenna mounted on the roof of the truck. The antenna is connectedto the receiver with a coaxial cable.The purpose with this Master Thesis was to develop and evaluate a new GPS-system,where the information is distributed using a LIN-network. Today, each unit requiringGPS-information is equipped with its own antenna and receiver. This solution has beenthe most cost effective to this point.
