A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

There are two different kinds of users of this equipment, technicians and system engineers. Technicians use the equipment to test and repair flight components. System engineers will implement new components in the equipment.The result of this project is a working test station with a new interface and two manuals..

Physical activity can reduce the risk of developing dementia, and studies show that people who already have some form of the disease can get a better memory function and find it easier to perform daily tasks if the activity is performed regularly. People who are diagnosed with dementia are generally not offered physical activity to a high extent, nor is there a wide range of equipment developed to suit the target group.The Bike Around project was launched during a workshop in Copenhagen and was organized by HCH and Techna Science with the aim to develop new training equipment for people with dementia. The workshop resulted in the development of a customized training bike where the user can get a biking experience from his wheelchair or favorite chair. By integrating the pedal movement with a prerecorded movie projected on a screen, the memory can be stimulated both visually and by the activity itself.Our assignment in the project consisted of three parts: design of the bike, movie playback and software programming. During the project a prototype has been created that meets the requirements of ergonomics and usability..

This master thesis aims to examine the methods of the conservation field and their visionabout maintenance and change, in terms of liturgical values. This is to be able todetermine if there is a need to develop the methods that the field of conservation has tosafeguard the intangible cultural heritage of the churches.This is mainly a literature review, focusing on different tutorials from the Swedish nationalheritage board, and different texts on liturgy aswell as Unesco's Convention for theSafeguarding of intagible Heritage (2003), ratified in Sweden in January 2011. A casestudy of the practical work has been carried out on three churches that have undergonechange. The application process and the results were important for this study.The conclusion is that the conservation field have ambitions to preserve the liturgicalvalues, but they do not have sufficiently developed methods to do so. Nevertheless, itappears that most cases of change in churches, increases the liturgical values..

Mobile Arts have a technical platform for handling maps and community-featured Points of Interest in cellular phones, where the users themselves can share locations with other users either in groups or public. Development of the platform regarding network communication has been included in this paper. The work evaluates different feasible business models regarding packaging the platform as a commercial application and also faces issues users have when using the product. Even if users found maps and POI interesting and cool in cellulars, the technical difficulties and lack of product focus during beta testing, were present. Therefore, the writers recommendation is more development of the platform and using a business model where Mobile Arts deliver to existing communities.

The case method is a relatively new pedagogical method in Sweden that is based on students exercising their skills in the analysis of complex situations and problems that are based in reality and that help students to see a broader perspective and context.The purpose of this study has been to investigate, through interviews with students and teachers, the advantages and disadvantages of the case method in teaching geography.The results of the study show that both teachers and students share almost the same opinion. The conclusion is that the case method is a didactic method that is well suited for teaching geography, as it is based on reality and develops the students? ability to analyze, argue and find solutions in several areas within the subject of geography. If a student is strong in these skill areas they can really benefit from the application of the case method in the teaching of geography, but for students who are weaker in these skills, the case method can be a disadvantage.

This report is the final part within our education, Industrial Organization and Economy focusing on Logistics and Management at Jönköping School of Engineering. The aim with this report is to coordinate recycle drives for deposited aluminum-cans and bottles collected from grocery stores within Jönköping county and locality.In the present situation both aluminum cans and bottles filled with drinks are distributed to the grocery stores by the brewery?s own distributers. At the same time as they supply the drinks they also discharge the grocery stores units with restored aluminumcans and bottles. To make it easier for the grocery stores to handle the goods in the future, all distribution of drinks ought to be directly delivered to the grocery stores own separate central warehouse.

The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP. The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in buildings..

The Thesis purpose is in the context of system development validate the Scrum Methodology. Projects concerning information technology are difficult to manage and tend to fail in quality, time or costs. Scrum presents a new view of the system development. Better cooperation between customers and developers, continuous follow-up on daily basis and extensive communication in the development team are all characteristics of Scrum. Scrum is described as a new paradigm by its founders but has been criticized by experts of system development too.

I takt med att antalet mobiltelefoner har ökat har även efterfrågan på fler tjänster för dessa ökat. Detta är en av anledningarna till att WAP-tekniken skapats och att den har fått så stor uppmärksamhet. WAP, Wireless Application Protocol, är ett kommunikationsprotokoll som gör det möjligt att utveckla tjänster för mobila klienter. Den har utvecklats genom ett samarbete mellan en mängd olika företag och är idag en öppen standard. För att kunna utnyttja den nya tekniken och anpassa nya tjänster bör man tänka på vissa faktorer såsom begränsningar gällande klienten, säkerhet och gränssnittet mot användaren.
