This report contains a degree project made by the mechanical engineering students Lennart Andersson and Daniel Jansson. The project has performed in assignment by SOMAS Valves AB in Säffle. SOMAS are leading in development on control and on/off valves. To maintain this position they always want to improve their products. One way in this development is valves that are more tightened.The purpose with our project was to investigate another seat design on a HiCo (High Cobalt Alloy) seat to a SKV 150 PN 25 valve and compare this to an original HiCo seat.By modifying the seat on a ball valve we want to achieve a valve that leaks lesser then a valve whit original seat.

Theory of mind är att kunna tillskriva andra människor mentala tillstånd som förklarar deras beteenden. Dessa mentala tillstånd kan röra sig om uppfattningar, intentioner eller känslor.    Theory of Mind Scale är en bedömningsskala utformad av Wellman och Liu (2004), som undersöker olika nivåer av theory of mind. Theory of Mind Scale är uppbyggd i skalsteg med stigande svårighetsgrad. Syftet med föreliggande studie var att översätta Theory of Mind Scale från engelska till svenska samt validera bedömningsskalan för barn mellan 3 och 4 år. Studien syftade även till att se om det fanns ett samband mellan dessa barns förmåga till theory of mind, impressiva grammatiska förmåga och impressiva ordförråd.      Valideringen i föreliggande studie visade att skalstegen i den amerikanska originalversionen av Theory of Mind Scale var applicerbara på barnen i föreliggande studie, med undantag för den sista uppgiften.

This paper reports a study in how interaction design and graphic design is affected in the process of developing an mobile application to complement the use of an existing webbsite. The paper also ask how developers are affected in this process by the use of designpatterns. The purpous of the report was to see how designpatterns affects the development of mobile applications and how the interaction and graphic design differs between various company webbsites and their related application. A study was conducted by comparing three diffrent webbsites with three related applications to find material for our thesis. Interviews were conducted on three diffrent companys that work professionaly with creating mobile applications.

When different type of programs are developed one wants to make these adjustable to future changes and requirements. It must be done a good design of the program from the beginning to make it possible to continue development of it without having to redo big parts of it to high costs. In the area of object orientation there are design pattern, which can be used to design systems that can be adjusted to new changes in an easier way. I have in this thesis chosen to take a closer look at how to design a program that sends SMS to cell phones through a system of an operator. One requirement on the program is that it has to be possible to change what operator to send though in an easy way.

The aim of the following paper has been to test the democratic peace theory through applying it on the conflict between Russia and Georgia in 2008.  This to either falsify the theory or come to the conclusion that the states? democracy was not satisfactory in regards to the definition of liberal democracy. The questions asked are: Was Russia and Georgia democratic states? Is democracy a protection from war? And which aspects of the liberal democratic theory, if any, were not satisfactory in either of the countries? The results show that the democratic peace theory is valid in this case and that neither one of the states were democratic.

The purpose of this paper has been to follow how a decision made has developed within anorganization. We have intended to find underlying causes for the development in order to contribute to the understanding of the lifecycle of decisions.The decision we have chosen is Gröna Skolgårdar (Green School Yards) within the city of Västerås. This project has aimed to make the school yards in Västerås more green, more beautiful and more useful for teaching.We have used Grounded Theory Method as our foundation, complemented with decisionmaking theory.The work with this paper has led to the conclusion that Gröna Skolgårdar changed over time, and did not turn out as first intended. This has had several couses such as how resources wasdistributed, political changes, and different views of the project.We have learned that over time a decision can take unexpected paths, and we have contributed with an example of how this can happen..

När ett nytt databassystem ska tas fram och införas i en organisation ska funktioner och krav på systemet identifieras och analyseras i en designprocess. Ett krav på ett databassystem kan vara att systemet ska uppvisa en viss prestanda. Designprocessen leder så småningom fram till fysisk design av databasen och dess applikationer. Det kan finnas flera olika lösningar för fysisk design av databasen och dess applikationer som tillgodoser kraven och funktionerna som ska finnas i systemet. Dessa olika lösningsalternativ ger olika prestanda.

Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.

The outset of this thesis is to raise questions on how we design for the mobile context and the capabilities of smartphones. Not only the presentation but also the use of input and interaction between a service and a user.This work evolves around sign up forms and answers the question: How does the sign up process affect the holistic perspective of a digital service regarding usability and user experience? This thesis consists of a case studies, and design experiments conducted on Twitter, Instagram and Randos sign up processes to explore if and how the usability, and the user experience could be affected and im- proved.This concluded some important aspects to be considered when designing sign up forms for a digital service.The usability, and the user experience is not only affected by user interaction, and the choice of input method but it?s also affected by which data the service is requesting, and more important; if that data is motivated to request by the service..

I chose to do this work because I believe that today?s industrial designprofessionals lack in their task of creating aesthetic experiences and aestheticdiversity.With my work, I want to question why the majority of today?s technical, massproducedeveryday products have such a similar design expression, andwhy alternatives are so few. Most of all, I take a critical attitude to today?sstereotypical industrial design aesthetics that I would describe as technical,masculine, and unnecessarily complex.I have designed a number of products that show alternative aesthetics in thissegment and as such I have chosen the vacuum cleaner. The idea is that mydesign will serve as an eye opener and demonstrate that there are alternativesto today?s homogeneous market.The result is three vacuum cleaners claiming three alternatives to currentofferings.

The Functional Resonance Accident Model is a method developed to analyze complex systems for the purpose of accident prevention. In FRAM-analysis a visualization of the complex system is created as an aid for identifying points of interaction in the system where the risk of accidents is high, and to determine where preventive measures are to be placed. FRAM Visualizer is a computer program developed as a tool for creating such visualizations.Many usability problems have been identified in FRAM visualizations created both manually according to established method and by using the FRAM Visualizer software. The purpose of this paper is to give a basis for how FRAM visualizations can be improved in accordance with usability criteria for use in future qualitative studies.The author suggests alterations to the FRAM visualization to resolve usability issues identified in previous articles and to achieve usability goals derived from visual communication theory. The design process is guided by established design principles.

Service branding is a subject that has been excluded from the traditional branding theory. Our main purpose with this paper is to distinguish what characterizes service branding. To do this, we have looked in to both service marketing theory as well as branding theory. We have also looked at the existing theory concerning service branding. Six qualitative interviews have been performed to explain what characterizes service branding.

This study is essentially based on my own questions concerning contemporary playgrounds. Why are they so unimaginative? What do the children say about them? Is it possible to create playgrounds less constructed, and with more natural elements? This report starts with references to literature studies, personal references and my personal view, and ends with a suggestion for a physical solution for an actual day care centre. The aim is to learn more about how the natural environment affects children, the importance of playing, and try to use this knowledge in a design of a day care centre. My main theme can be summarized in the following question: Why is natural elements in playgrounds considered to be healthy for children? I wanted to create a playground with natural characteristics which I myself would have appreciated as a child.
