In 2002, the euro as a common currency did replace the national currencies in the EU member-states that did choose to take part in the EMU. It was then viewed as one of the greatest accomplishments ever to be made by the EU. However, during the latest years, the economic situation has deteriorated in several EMU member-states. This affected the whole euro-area and the current situation is referred upon as the euro-crisis. In 2011, at the time of the euro-crisis, the Heads of State or Government of the euro-area did reaffirm their full commitment to strengthen EMU.

This thesis studies path generation for industrial robots of six degrees of freedom. A path is defined by connection of simple geometrical objects like arcs and straight lines. About each point at which the objects connect, a region, henceforth called a zone, is defined in which deviation from the defined path is permitted. The zone allows the robot to follow the path at a constant speed, but the acceleration needed may vary. Some means of calculating the zone path as to make the acceleration continuous will be presented.

Denna rapport har jämfört olika path tracking-algoritmer för att se vilken som presterar bäst för spelagenter som färdas i konstant hastighet. Tre vanliga path tracking algoritmer som ofta används inom robotik har valts ut för undersökningen, Follow The Carrot, Pure Pursuit och Vector Pursuit. Algoritmerna har implementerats i C# och simuleringarna har genomförts i Unity 4.0. Path tracking-algoritmerna har testats på ett antal olika vägar för att se hur de lyckas följa vägen. Av simuleringarna så visar det sig att Pure Pursuit och Vector Pursuit presterade likvärdigt för spelagenter i konstant hastighet samt att de presterade bättre än Follow The Carrot..

Det statliga järnvägsnätet som byggdes i Sverige under 1800-talets senare del har haft stor betydelse för landets tillväxt. Banornas sträckning och byggsätt gav upphov till livliga debatter i riksdagen som slutligen resulterade i det stambanenät som än idag ligger till grund för Sveriges transportinfrastruktur. Vilken spårvidd som skulle användas var en viktig fråga i debatterna, och att Sveriges statsbanor skulle ha en och samma spårvidd var långt ifrån självklart.Denna studie undersöker och analyserar varför de norrländska stambanorna slutligen kom att byggas med samma spårvidd som övriga landets stambanor, och därigenom bli en integrerad del av det statliga järnvägsnätet. Ursprungligen var de norrländska banorna tänkta att byggas med smalare spårvidd, något som skulle innebära att detta nätverk skulle ha isolerats från södra Sveriges. Detta beslut ändras emellertid innan byggandet påbörjats.Genom att kvalitativt studera riksdagsprotokollen från debatterna om järnvägen som byggdes mellan Storvik till Torpshammar och vidare till den norska riksgränsen för att ansluta till en norsk bana kommande från Trondheim, undersöks de argument som framfördes i debatten ur dels en sociopolitisk och dels en ekonomisk synvinkel.

A proposal of a new path from the inner town of Gävle to a small cultural area in the seaside. The thesis contains historical background, analysis over town and the area, and a proposal of a new shape for the postindustrial area near the stream called Gavleån. .

The aim of the study was to describe how nurses experience to handle the alcohol issues among young people and how they can identify young people?s alcohol problems, abuse and dependence. Empirical articles were searched in the databases Cinahl, Medline(Pubmed) and Discovery and resulted in the inclusion of 14 scientific articles. The results showed that nurses find it difficult to raise the issues of alcohol with young people, this partly because they feel that they have too little knowledge and that it is an emotional issue to raise. There is help instruments available that nursing staff can use to raise this issues and to identify alcohol problems, abuse and dependence.

Background: In scientific literature there are various treatment programs for people with alcohol dependence described, however, are psychosocial factors that promote recovery process described to a limited extent.Purpose: To describe the psychosocial factors that promotes recovery from alcohol dependence.Method: Literature study of ten scientific articles, published between 1999-2011 with both qualitative and quantitative design.Results: According to the literature, the recovery process can be considered to begin when a person with alcohol dependence reached his personal rock bottom. The longer the recovery progresses, the greater are the overall level of performance. Social support is described as an important factor to prevent relapse and reduce the need for professional help. Self-belief and support of self-help groups are described as important to maintaining sobriety. Social support and influence from family members was related to increased ability to analyze and assess their situation during the recovery.

Background: Exercise dependence is a behavior where some people get very strong feelings for their training. This dependency becomes a problem when it affects individuals? life in a negative way. Individuals with low self-esteem have been found to have an increased risk for exercise dependence. Self-estem is associated with Self-compassion, which is to have compassion with oneself in pain and difficult periods.

The aim of this paper is to examine the layout of public spaces and its effect on human behavior with focus on the relation between pedestrians and cyclists movement patterns in a specific path. The study emanates from the security aspect of pedestrians and cyclists, and builds upon previous theories and empirical studies about perception, security, information design, environmental psychology and behavior. The result shows that individual behavior and movement pattern differs with age, purpose, physical- and other conditions, and layout of the surroundings. A design proposal for improved layout of a path and a node between different oncoming paths has been developed to aid the users? needs, where a separation of walkways and bike lanes forms zones of security for the purpose of better orientation and a better flow between the users..

Ett spels karta är begränsande i det att när man valt en viss storlek kan man inte gå utanför den ramen utan att göra relativt resurskrävande operationer. Denna undersökning genomfördes för att se om en trädstruktur kan användas som lösning att hantera en honeycomb-struktur på ett lämpligt sätt för att ständigt kunna utöka ett spels karta. Resultatet visar att det är möjligt att använda trädstrukturen relativt bra till växande kartor men att det inte är att rekommendera till spel, eftersom strukturen i sig är en omväg. I samband med denna karta skapades en slumpmässig path-generator som skulle kunna användas till att generellt skapa slumpmässiga kartor i spel. För att se vad försvårigheter man stöter på när man utvecklar en slumpad map-generator, vilket visade sig vara svårt i och med att man hittade många specialfall..

The essay aims to compare Swedish and Finnish decisions regarding refugee policies by tracing them back to the critical junctures when the policies were established, in order to explain why there are big differences prevalent today. The questions asked involve the motivations of the refugee policies and how they have changed over time.The theoretical framework employed is based on historical institutionalism and path dependency. By using a most similar system design and process tracing, material in the form of government declarations and government bills are studied and summed up in two analytical models. The results show that there might be a weak path dependency in the case of Finland. However it is more apparent in the case of Sweden, with frequent statements of a generous refugee policy that is characterised by humanity.

The transition from a planned economy to a market economy was initiated in Russia in the beginning of the 90s. The three components: privatization, liberalization and stabilization constitute the trinity of the transition theory. This thesis has its focus on the privatization, that also can be referred to as a piratization of Russia. The purpose of the thesis is to explain what went wrong with the privatization, and also why it went wrong. A few men, called oligarchs, got their hands on great wealth which has lead to an abuse of power.

AbstractOil rich states all over the world share a common feature. They are less likely than other states, depending on other resources, to be ruled democratically. In this essay Saudi Arabia has been studied with the purpose of trying to find which mechanisms that lie behind why oil rich states do not have institutions or institutional change that promotes democracy.Saudi Arabia has the world's largest known reservoir of oil. The oil brings huge revenue each year to the Saudi Arabian government. Why have Saudi Arabia not developed democratically when their economic growth suggests that to be a natural step? Under the framework of historical institutionalism and path dependency theory, I have used process tracing trying to track the mechanisms behind Saudi Arabia's authoritarian rule down.

This essay brings up how experienced texture artists in game development can get comfortable in their workflow and therefore not spend time on learning new techniques that in the end could be more efficient. We base this on theories that people often choose the path of least resistance, which in the case of an experienced texture artist would be the path they have learned and are comfortable with. We also talk about the popularity of Photoshop and that many of today?s texture artists in the game industry are using it and that this could be because Photoshop was one of the first programs that could be used well for texturing. Because of this many learned to use it and stuck by it and then taught Photoshop to new texture artists because that is the program that they know.

Syfte och frågeställningar: Syftet med studien var att undersöka om ortorexi enligt studiens definition förekommer bland gymnasieelever i årskurs tre. Frågeställningar: 1. Uppvisar gymnasieeleverna en kostfixering enligt ORTO-15? 2. Uppvisar gymnasieeleverna ett träningsberoende enligt Exercise Dependence Scale-21? 3. Uppvisar gymnasieeleverna ett ortorektiskt beteende enligt studiens definition? Metod: Detta är en kvantitativ studie med enkät som insamlingsmetod. Totalt åtta randomiserat utvalda kommunala gymnasieskolor inom Stockholms kommun deltog. Två olika tester användes; ett om kostfixering (ORTO-15) och ett om träningsberoende (Exercise Dependence Scale-21). Krav för att delta var att eleven är född 1996 eller tidigare. Totalt delades 234 enkäter ut, 226 var korrekt ifyllda och användes i studien. Det interna bortfallet var alltså åtta enkäter (3 %).Resultat: 23 % av deltagarna uppvisar en kostfixering enligt ORTO-15 (35 poäng eller mindre), varav 18 % män och 82 % kvinnor. 66 % av gymnasieeleverna uppvisar tendenser till träningsberoende, medan 2 % klassificeras (varav alla var män) som träningsberoende enligt Exercise Dependence Scale-21. Totalt klassificerades tre män (1,3 %) som ortorektiska.Slutsats: Ortorexi, enligt studiens definition, förekommer hos gymnasieelever, men endast i en väldigt liten del av den studerade gruppen (1,3 %), och endast bland män. Resultaten för träningsberoende enligt Excercise Dependence Scale-21var liknande (2 %, endast män), men en betydligt större del (66 %) uppvisade tendenser till träningsberoende. Nästan en av fyra (23 %) har en kostfixering enligt ORTO-15 testet..
