The purpose of this article is to describe the discourse in which public-private partnership (PPP) resides, within the Swedish parliament, in the field of infrastructure. I have chosen to look at the latest three years deliberation where PPP appears in parliament bills.This case study is based upon discourse as a qualitative method. Five indicator signs which is history, comparison, geographic location, vision of growth potential and solution controls the context of PPPThe result of the analysis was that a clear discourse was unravelled. A first rather surprising conclusion shows that it is possible to disconnect the discourse from PPP. PPP is not important by itself, the result shows that it only play the part of possible solution to the problems related to the discourse and does not have any value in its own.This result lead the conclusion that PPP is no more than a tool for politicians to get as much out of their infrastructural aims as possible, as rational vote-maximizing actors.

The goal of this paper is to provide a model for a sustainable electricity system to an island, in the Pacific Ocean near the equator.The method which has been used is to model supply and demand of electricity in the computer program Stella, through the creation of a dynamic system that balances them against each other. The result from the model will then be used to calculate the electricity price per kWh for the island.The result of the work is that electricity from solar energy is comparable with electricity produced from oil, if the oil pays for all its external costs, and the potential for pumped hydro storage plants is located. It also requires that consumers of electricity can be their own producers to avoid the expenditure of tax and reducing the cost of distribution. But since oil is a finite resource and has had a rising cost in recent years, while solar energy has had a declining cost, perhaps this will be a more competitive solution in the future.

 This report will describe a project between two students from Karlstad University and Markus Norström from Hovercraft solutions. The project aim was to develop a cabin for the hovercraft 380TD. The project was divided into two sub parts; one concerning the design of the cabin and one concerning the engineering. Throughout this rapport you can follow the engineering part of the project. The project has followed a systematic product development process resulting in optimized results for material selection and engineering solutions.

Karin Boyes Crisis (Kris) was published in 1934 as a contribution to the contemporary ideas of moral issues, challenging the dominating traditionalism within the literature critisism.With different kinds of stylistic procedures is Crises expressing a self which seeks to relieve itself from the repressing experience of Language. The text shows an attempt to create meaning beyond the conventional system of linguistic signs, beyond the tradition of literature.The focus in the essay is the self; the self is the basic structure and the theme of the text. Crisis shows it?s self-assuredness and points out a dialogue with the nietzschean philosophy. Nietzsche claims that the truth is a rhetorical creation, something which the language produces in the will of power.

The paper is a discourse analysis of the liberal environmental discourse in Sweden today. It is based on articles in two of the main liberal Swedish newspapers, Dagens Nyheter and Sydsvenska Dagbladet, and a liberal periodical, Neo.The purpose of this study is to analyze how the environmental problems that have been produced by the industrialised society, especially global warming, are seen upon in the liberal discourse in Sweden today. The theoretical point of departure is a discourse analysis that as a method seeks to analyze the material to reveal what assumptions the discussion departs from, and what assumptions the discussions reject.The thesis concludes that the main trends in the discussions are to position the environment against the financial system and state that the capitalist system is the only system that can solve the environmental issues. The existing environmental problems are not denied, but constantly belittled and only considered to be a problem if it poses a direct threat to humans. The solution for these environmental problems is believed to be the strengthening of the financial system and the development of new technologies..

In motorsports competition, safety reasons require that the vehicle is equipped with some form of protective roll cage. The roll cage should withstand the forces involved in a collision to protect the driver and the co-driver from the vehicle body deformation. The roll cage also works to protect the vehicle from excessive deformations to more easily make any repairs afterwards. For the roll cage to be certified and approved for motorsports competition, it requires that the cage is built after one of the recommended options. One of those options is to design the roll cage like a cross-construction at the driver and co-driver doors.

This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.

This paper evaluates the prospects for utilizing aquaculture effluents as a nutrient source in organic hydroponic, as is the case in aquaponics. The development of organic hydroponics is dependent on replacing synthetic fertilizers with organically derived nutrients, such as those found in aquaculture effluents. Also, in hydroponic cultivation the establishment of a plant pathogen suppressive micro flora is part of the plant protection strategy. Therefore, both nutritional and microbial qualities of aquaculture water and organic hydroponic nutri-ent solution were analyzed and compared. Results showed both aquaculture water and or-ganic hydroponic solution to be deficient in a number of essential elements, although or-ganic hydroponic solution was closer to recommendations.

This diploma work project is a product development project which purpose is to redesign a braking system for a walking frame. The system that was developed diverges the force from the user to braking power, and includes a service brake as well as a parking brake. The most important components of the system are a grip handle on where the user holds on to and a braking handle on which the user operates the brake from. The system also includes a power transmission component, braking package and other mechanical components. All of the components wasn?t developed in this project, several off them has been reused from the existing system.This product has been developed to meet the requirements and standards presented from the principal, Ahlberg Leber.

We performed our thesis at SCA Hygiene Products in Falkenberg. Our task has been to present a suggestion for a solution of the packing of giveaways that the company uses.In the current situation the work is performed manually, and the company wants to automate the process. In the following report, we present the different solutions that we have developed in our definite model. It includes a picking solution, a shaking table and trays. The product choices we have made are based on existing solutions.To help, we have used Fredy Olsson's books in principle and primary structure.

An Interoperable Fare Management system for public transport has been a struggle for the actors in industry of public transport. A lot of effort has been put into creating a smart card solution that enables the travellers to use the same card for paying and holding the ticket regardless geographical position in Sweden. That project has failed, mostly due to a lack of taking non-technical actors and aspects into consideration during the project process. This thesis highlights the major actors and their responsibilities. The ARKTRANS framework is used as analytical tool to identify different roles. Throughout the thesis a sociotechnical perspective is used. The developed method in this thesis is suitable for mapping of actors and responsibilities in a network surrounding a complex technical system.

WebGL is a standard for drawing graphics in a web browser. Currently it isn?t widely understood how consistently WebGL performs across a majority of the de- vices that support it. Determining if an image looks correct to a human observer is an interesting problem. The solution for this is useful when developing WebGL applications, since a developer could make better informed decisions during de- velopment.

In today?s society the average person is flooded by information from everywhere. This is in particular the case when using the Internet; consider for a moment the fact that a decent search engine at this moment scans 8 058 million homepages. For a user that repeatedly comes back to the same site, the case is often that they know what they are looking for. The problem is to isolate the important information from all the other information embedding it.We would like to state that we have found one possible solution to this problem, where the user himself can define what information he is looking for at a specific server, then scan the server when visiting it with his browser.

Detta examensarbete genomfördes våren 2013 på Karlstads universitet där TD Rail & Industry i Västerås stod som uppdragsgivare. Projektet innefattade att kartlägga nuvarande omlastningslösningar av enhetslaster mellan järnvägstransporter och vägtransporter, och utarbeta en konceptuell omlastningslösning med fokus på att öka järnvägstransporternas flexibilitet gentemot vägtransporterna. Där vikten lades på att utarbeta ett välarbetat helhetskoncept.Projektet genomfördes med designprocessen som grund och innehöll bland annat momenten; förstudie, kravspecificering, idégenerering, konceptval m.m.Resultatet blev en vidareutveckling av det redan befintliga systemet CCT som bygger på horisontell överföringsteknik och möjliggör därför omlastning av enhetslaster direkt under kontaktledning. Skillnaden mellan RES och CCT är att man tagit bort ombyggnationen av tågvagn och lastbilschassi, som var en av CCTs stora svagheter, genom två hydrauliska ?teknikplattor?.
