Detta arbete undersöker 4 olika algoritmer som används för bred kollisionsdetektering. De olika metoderna för bred kollisionsdetektering kan delas in i 4 olika kategorier. Algoritmerna som är valda att representera varje kategori är Bruteforce, Sweep and prune, Hierarchical grid och Bounding volume hierarchy. Fokus i arbetet ligger i att mäta deras lämplighet för spelmotorer där det är viktigt att algoritmerna kan köras i realtid.Algoritmerna körs i simulationer av olika miljöer. Där antalet objekt, hur många som är rörliga och objektens distribution varieras mellan miljöerna.

Virtual communities are a phenomenon that is becoming more common as the information technology comes with in reach for the general public. This report will bring the theories and construction of a virtual community together. The purpose of this report is to describe the different theories that have emerged from the research within this field and to examine the work procedures that have been used during the development of a site for a MDA-community. The MDA-website is a homepage on the Internet that was developed to bring the students closer together. The report describes the work of the project group, why the website was not completed and at the end the theories are looked at on the basis of the construction of the website..

The aim of this study was to examine the relations between sense of coherence (SOC), perceived social support and mood, the study also included gender and civil status in the analysis. In the analysis mood was the dependent variable. The study included 81 respondents, all students from Växjö university, who answered a survey with three parts: SOC 13, Mood Adjective Checklist (MACL), and an own constructed instrument that measured perceived social support. The result showed that those with a high SOC tended to have a greater mood. High scores on perceived social support also were related to a greater mood.

Today, we see tendencies of politicians being more active in social media using selfies. According to previous research using selfies is associated with being self-centered and narcissistic. It is not known though what implications the behavior will have for a selfie-using politician in terms of chances of being elected. This study aims to contribute to the research on political communication and social media behavior. More specifically the study intends to investigate whether there is a difference between voters' views if a politician uses selfies or not, and whether there is a difference by gender.

A geographical position and its social, cultural and political context as well as climate and specific physical characteristics define the scope for a landscape design project. This has become clearer for us in our master project where we have made a Design Program for the outdoor environment of Wollo University in Dessie, Ethiopia and analysed and reflected on the work and process. The aim for the project has been to design an attractive and functional outdoor environment for the Campus, based on the inventories and the needs and wishes of clients and users. But, the aim has also been for us as landscape architect students to gain a greater knowledge about landscape architecture and the design process by position ourselves outside our usual context. The method has been open and seeking where the site, literature studies, dialogues with people and our own experiences from the field study in Ethiopia has influenced the work. Wollo University is situated 400 kilometers north of Addis Ababa, in a mountainous landscape. It faces problems of heavy rainfall during the summer, soil erosion, a lack of essential facilities, and is still a construction site with empty spaces in-between buildings and infrastructure.

In this thesis we have examined opinions of the social web in Scandinavian Library journals. Our interest lies in aspects about the social web, and above all about Library 2.0. The central question is how this new technology, a growing digitalization, and a social web that focuses on interactivity and participation affects opinions about libraries. We have investigated opinions about Library 2.0, with respect to three different dimensions: The role of the library in society, power/hierarchy and knowledge. The method used in this thesis is idea analysis using these dimensions as analytical instrument.

The construction industry has demands on energy use in permanent buildings. How much energy that is permitted to use during the time the building is produced has no requirements. The purpose with this study is to learn how far Skanska has come with the work of making the building site more energy efficient.A literature study has been performed in the beginning of the study to survey what energy efficient arrangements that can be applied and how they operate. Using site visits and interviews the situations on the building sites have been studied as well as the energy efficient measure that are in use.Skanska has come a long way with the work of energy efficient building sites and they keep improving. They have improved half of their cabins so they use 50 % less energy.

This essay discusses the import of cod (Gadus morhua) in Sweden during the Middle Ages through isotope analysis of cod vertebrae. The isotope analysis is used to trace the cods origin to either the Baltic Sea or the Atlantic Ocean. The bones were subjected to d13C, d15N and d34S analysis; 64 of  the analyzed bones met the quality criteria. The isotop data showed that import of Atlantic cod was significant in medeval Sweden. The analysis suggests that there is no specific time or event that the sites start to import cod but this varies from site to site. .

Agile as an idea was created in 2001 through the Agile Manifesto with focus on social relationships, communication and flexibility. This was a reaction to the traditional, hierarchical organization with the goal of restoring balance within organizations in the IT business. Today we can see a transit of Agile from the IT-industry to other industries and areas, such as HRM.There is a challenge in attempting to traditionally control a social idea such as Agile, and there is a lack of empirical studies of the organizational context and its effect on the interpretation of Agile in practice. This study is an attempt to connect Agile to the science of business administration.The purpose with this study is therefore to research the organizational contexts effects on the interpretation of Agile in practice, within IT and HRM. Where Agile is established or well known.To fulfill our purpose we chose social constructivism as our scientifically approach, and conducted 12 in-depth interviews.

This essay concerns the site of Pompeii and its preservation. The aim is to investigate what causes the decay of the ruins, how to prevent it and what consequences the tourism has on the site. The material consists of interviews with three Swedish scientists who are currently working with documenting a block in Pompeii. The result reveals a large number of threats against the city, such as climate, tourism and an inadequate economy situation. Examples of solutions are more investments which can be used for restorations and reconstructions, and guards to prevent vandalism.

Which factors do the different categories mean justify the placements?3.

According to the European Union waste hierarchy, waste should first of all be minimized. Reuse and material and energy recycling come next. Lastly the waste should be thrown at the refuse tip. In the inner city of Stockholm waste handling can be done in various types of ways. The solutions vary as a result of the type of architecture of the building and its condition.

Companies in the apparel industry are becoming increasingly responsible with regards to the social and environmental issues related to textile production. Despite these tendencies, there are great insecurities surrounding the concept of CSR and the effects on consumers of CSR communication. There is currently no model for breaking the concept of CSR down into smaller elements, specific for the apparel industry. In the first part of this thesis, we create such a model, applicable in a consumer communication context. In the second part, we investigate the effects on consumer attitudes and intentions of communicating the different elements of CSR presented in the model.
