This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.

C3LOOPS is an application for DJs and VJs based on surface interaction. A system is said to be based on surface interaction if it presents content on a two dimensional, endless surface that a user navigates through zoom, pan and incremental text filtering where processing is tightly coupled with the content without breaking the workflow. C3LOOPS is designed to encourage improvisation and collaboration. During improvisation changes occur rapidly. Allowing navigation through time as well as the two spatial dimensions of an interaction surface the possibility of unlimited undo operations opens up.

The primary purpose of this thesis is to investigate the operation of membership criteria, which are applied against countries that wish to join the European Union (EU). More specifically, the importance of some criteria in comparison to others is considered. To answer this proposal, three questions are posed: What are the EU membership criteria? Are some criteria more important than other criteria? Does the EU treat candidate countries differently in applying the membership criteria? Three countries are used in this analysis, each country representing one recent enlargement round: Poland (2004), Romania (2007), and current candidate country Turkey. Both official documents, such as EU treaties, and unofficial documents such as statements from EU leaders are used to analyze the application of membership criteria.

In today?s society it is not uncommon for people to move across borders. We are more likely to work and study in other countries, initiate cross-border relationships, acquire property in other states and change our residence. Therefore it is not uncommon for a per-son to leave inheritance in several states. The laws of succession differ between countries which creates an uncertainty among the devisors when planning their successions.

This essay compares the public debate in Sweden 1992 caused by the reforms introduced by the then government giving parents a free choice of schools for their children with the current debate in France about proposals for a similar law there. The study concentrates on the positions taken by the teachers trade unions, in Sweden Lärarförbundet and Lärarnas Riksförbund (LR) and in France SGEN-CFDT. To do so it is necessary also to study the arguments given for and against the proposals by the political parties.Some of the differences between the debates can be attributed to different circumstances. The Swedish reform was related to the opening up of possibilities to run private schools, which previously had been rare in Sweden. The French debate has no such connections.

To encourage and increase the motivation to physical activity by using new information and communication technology, in order to change our behaviours into a more healthy lifestyle, could be one approach to promote public health. In our study we examine how gamification, which is about implementing classical game design elements from the computer world in a non-gaming context, can be a tool to increase the motivation for physical activity. Since similar studies already have been done we chose to focus on analyzing how different player types from Bartle?s taxonomy can be affected by the usage of a gamification application. A group of students were therefore picked and during a two weeks? period they used the application Fitocracy where they logged their daily excercise.

Charles Hartshorne (1897-2000) was a religious philosopher. He adopted and developed the cosmologic thinking and concept of God from the philosopher Alfred North Whitehead, he was also influenced by Heidegger, Spinoza and other philosophers. According to Whiteheads religious philosophy Hartshorne claimed that there is a dualistic transcendence within the Godhead. A dualistic transcendence where one unity/transcendence of God is abstract, outside the creation and time and therefore is eternal. The other unity (or transcendence) is inside time and creation and closely in process to it .

With Microsoft's new operating system, Windows 8, a new type of applications were introduced, Windows Store Apps. These applications must meet certain requirements in order to be uploaded to Windows own store for apps. There are also guidelines to follow. The requirements and guidelines include appearance and functionality, such as a common search function in the applications to contribute to a more unified experience. How does these requirements and guidelines influence developers? Whether the development of the Windows Store Apps gets more difficult, or perhaps even simpler, is studied and evaluated in this report.

This report is the result of a sub-project of a larger project to create a platform formathematical education. The sub-project focuses on authentication with associ-ated security, where security is emphasized. The project environment is Java EE 6where GlassFish 4.0 acts as the server. The project has been divided into threeparts; password encryption, Java EE authentication and brute force attack. Thepassword encryption part focuses on examining different hash functions executionspeed, the result shows that none of the examined hash algorithms is suitable fordirect use.

The Youth Outcome Questionnaire 2.0 Self Report (Y-OQ 2.0 SR) has been implemented in residential treatment centre in the Municipality of Örebro as a result of the strive for a more evidence-based working approach within social work. This study aims to examine how personnel and adolescents describe the treatment/counseling and support and the application of the Y-OQ 2.0 SR in the units. The questions cover the values the personnel and adolescents ascribe to the application of the Y-OQ 2.0 SR, if the result from Y-OQ 2.0 SR is congruent with how the adolescents have been affected during the placement, which obstacles and/or possibilities emerge in the management of the instrument and if there are any indications that the Y-OQ 2.0 SR is advantageous or disadvantageous in the treatment process. The study has a qualitative approach; four interviews were carried out with adolescents and five with personnel. The result shows that structure is an important component in attaining a change in behaviour.

Väldesignade spel är naturligt motiverande för att hålla kvar sina spelare. För att ett spel ska bli framgångsrikt är det viktigt att det innehåller motivationsförstärkare. På senare år har element hämtade från speldesign även använts inom andra områden, utanför sin vanliga kontext. Detta sammanfattas i begreppet gamification (sv. spelifiering).

Länge har utvecklare kämpat för att genom kreativa implementationer av gryende teknologi, särskilja och sprida sina applikationer och tjänster i konkurrensen av ett ständigt växande utbud. En av de senaste trenderna för att framkalla ett ökat engagemang och förbättrade prestationer bland användarna är gamification. Detta innebär processen att införa spelliknande moment i applikationer för att öka deras interaktionförmåga och på så sätt möjliggöra för motivation att uppstå inom användaren. Lyckade exempel på gamifierade applikationer har snabbt sprungit om sina konkurrenter både vad gäller användarlojalitet och popularitet vilket får många att fundera på nya användningsområden för tekniken. I detta arbete vill vi besvara frågor kring hur gamification kan användas för att öka engagemang, kunskap och prestation hos användarna i ett av dessa nya områden, försäljning.

This Masters thesis aims at investigating how 15-year old girls use the Internet, particularly on their free time, taking a source critical perspective. It includes group interviews. The main question of this thesis was whether there is a need for specific user education. The following four questions were asked: What do they do on the Internet during their free time? In what way do the girls learn how to interact with each other on the Internet? How do they relate to different types of web pages and materials from a source critical aspect? What content do they consider to be relevant in a user education? The study is mainly focused on information use and information behaviour in different contexts.

In this study we examine trade patterns between Turkey and 13 member states of the European Union and how these have developed over the time period of 1983 ? 2006. To represent the industrial and agricultural goods included in the study we look at the United Nations Standard International Trade Classification (SITC). Following, we investigate internal differences in the EU by selecting four countries each to represent the Northern and Southern countries of the EU. Internal differences were studied in relation to the amount of trade occurring between Turkey and the Northern and Southern countries.

The research in this thesis attempts to understand what happens when children (3-6 years of age) interact with each other in the context of free play in two pre-school settings when adults are not involved. The aim of the study was to get a closer look at how children create relationships and how they protect and defend their interactional spaces. Data was gathered through ethnographically inspired methodology, using video observation to capture the everyday interactions of the children. Results were analyzed using a phenomenological approach to peer cultures. Previous research suggests that it is very important for children to maintain their interactions with peers and gaining access to play.
