This paper presents techniques for speeding up commonly used algorithms forbounding volume (BV) computation, such as the AABB, sphere and k-DOP. Byexploiting the possibilities of parallelismin modern processors, the result exceedsthe expected theoretical result. The methods focus on data-level-parallelism(DLP) using Intel?s SSE instructions, for operations on 4 parallel independentsingle precision floating point values, with a theoretical speed-up factor of 4 ondata throughput. Still, a speed-up between 7?9 are shown in the computation ofAABBs and k-DOPs.

The purpose is to improve IKEA´s understanding of how their target group of 12 to 18 years old boys and girls thinks when they visit the showrooms in the department stores. What make them enter the showrooms? Is it the colours, the furniture or the whole concept? How are they inspired to furnish their own room? Do they get ideas from the showrooms or are they looking for a specific furniture? These types of questions have increased young people´s interest for design and decoration over the last decade. It transpires with help from an article written by Vittorio Girotto and Michel Gonzalez how children are influenced in an early age by their own temperament and their natural surroundings. Children reasons and acts according to what they believe adults would have done in a similar situation.The methods that have been used during this project are interviews, surveys, observations, hypothetical persona, persona and ABL (IKEA´s own method).

The aim of this bachelor thesis is to find out how young adults experience the library and the space that they have access to. I used semi-structured interviews to find out about this and interviewed eight youths between the ages of 15 and 18 in a medium sized city in the province of Västra Götaland in Sweden. I then analyzed the material with the help of Goffman?s theory about front stage and back stage. I also did a small comparison with results from previous studies.The result showed that the youths generally liked the library and the staff but they had opinions on some issues.

The purpose with this thesis is to investigate how the logistic and the configuration of the terminal buildings and the perceptions of the passengers at Stockholm Arlanda Airport are related to each other, and what effect it has on the passengers and their traveling within the airport.The focus will be on the logistic at all four terminal buildings that is within the Airport. To create a perception of the logistic at the Airport and how it is related to the passengers perceptions, the investigators need to make knowledge of the terminal buildings, and thereby try to link the logistic with the perception of the experience room.Swedavia is the company that own, operate at and manage Stockholm Arlanda Airport. The investigators will make an interview with employees at Swedavia to get a more profound understanding of how the company is thinking about the logistic issues that they need to overlook. There will also be interviews with travelers to get their perception of the logistic, design and atmosphere at the Airport.Observations will also be made at various times at the Airport with focus on all of the terminal buildings. The investigators use qualitative and quantitative methods to reach a result. To achieve a result, the investigators will use theories and scientific facts and other available facts that will be helpful to reach a result that will be analyzed..

The aim of this study is to understand how the library environment affects the experiences and feelings of public library users. In order to concretise this, the study sets out from the public library in Bollebygd. We wanted to find out how the library users experience the library environment. Does the library environment affect the meeting between library users? How does the environment affect their moving patterns inside the library? Which environmental factors influence the users' experiences? Our questions were: how do users experience the library environment - as a mediating space for information and culture? - as a social room and meeting place? The material used to attain the purpose of the study consists of qualitative observations and interviews, and literature studies.

This thesis examines how to improve the exhibition of products within retail for clothes and gift articles. The purpose is to investigate and test how light sources and different directions of light affect how the products are perceived regarding their exhibition. Our question formulations are:To what degree does the level of light in combination with the background of the interior design of a shop affect whether a product is perceived more or less attractive?What can we recommend to make the exhibition of products more attractive? From our observations shops nowadays have relatively high levels of light when they expose products on vertical areas. We have looked on the recommendation from ?Energimyndigheten? in order to see what they think is important when designing retail lightening.

The purpose of this study is to describe and analyze the places importance for young people with disabilities. The study?s central questions are what type of places they visit and what characterizes them. It is also about answering the questions why the places are visited and what meaning this has for participation and identity. The study´s central concept is room/place, participation and identity.

The purpose of this report is to analyze the advantages of using programme software to monitor masshauling instead of using the conventional method. A comparsion between different programs will also be conducted in an attempt to determine the most affordable. This report is written for NCC Construction AB to help them choose a software most fitting for future projects.The report is based upon literature such as information taken from the developers website, existing reports with similar context, interviews with sellers of the software and interviews with people working in the building sector.The result of this report shows that there are several advantages with investing in a software that helps the management of a project and that it is something that should be taken under consideration instead of the existing method. Topcon is a clear favorite following the inquiries comparisons as done, when they deliver a complete system and not only a supplement to the current approach. Scanlaser are just in the beginning of its development, and is so far only out with an early version of the software, while Topcon has been brought further in development and therefore has more features in the program.

The report describes the thesis I, Philip Bergstrom, have done at the University of Gotland. The work comprises 15 credits and is at bachelor level and has been done in collaboration with Lyktan Bankeryd Belysning.The project consists of developing the design of a kitchen lamp for the Swedish home following the catchwords stripped French bistro that will fit into the Lyktan Bankeryd lighting spring collection 2013, and it should not look too alike any existing lamp on the market today.The work includes analysis of the company's current products and the image the company wants to project, analysis of three other companies' products to draw inspiration from, and a simple ergonomic study of the lights in the kitchen.The final result achieves the demands made and fits well in the intended environment, there is also the possibility for further development of both a floor lamp and a wall lamp..

Information technology (IT) have for several decades been used in university education. An increasing number of classrooms today are built around a concept which uses IT in collaboration with the room itself. However, little is known about the experience of university teachers when working in such classrooms. This study examines the views and opinions of teachers at a Swedish university regarding using and interacting with these classrooms. Furthermore, we identify possible underlying factors that influence these views.

This master thesis in library- and information science is about the intermediary function of the library room from an environment-psychological point of view. Young people are a group in society who often reduce their visits to the library when growing up. There are lots of reasons for this maybe more attractive activities occur outside the library doors, making the young choose not to use the library. But if the library interior is attractive in itself, and has a welcoming atmosphere, there might be a change and the young people may well choose to pay the library a visit. What is important to young people how do they want their library room to look? Our purpose is to see how the physical environment affects young people in libraries.

The following project has been made in collaboration with, Denator AB, a biotechnology enterprise. One-dimensional electrophoreses have been used to analyze protein contents of tissue samples. Tissue samples have been either treated according to the company´s newly developed tissue treatment technique or not treated at all and comparisons between these samples have been made. In order to see differences in protein patterns between samples more clearly, a conversion method has been developed where electrophoresis gel visual patterns are used to produce curves, similar to densitometer curves.Denator AB would like to know if the proteins in their treated samples will change visibly over 48 h when incubated at room temperature. This has been investigated using the above mentioned method.

The purpose of my report was to find out how music can benefit the language development of children, whilst getting a glimpse of how the educators in preschools use music as a tool for the language development of children. During the course of the report I?ve used the sociocultural perspective theory as a foundation to stand on, this is most of all visible in my analysis and discussion of the result. In the result we can see that the educators possess insight in the importance of music in childrens development, and that they therefore give music a lot of room in their work. Songs where rhyme and language play are allowed are common elements at the preschool that attracts the children and makes them want to partake. Songs sung with movement is a commonly used combination which also serves to further lift the childrens language development when they, through movement, give meaning to the lyrics. It does however take a devoted educator to make music with the preschool children and to support them and making them want to do it.

 The purpose of this study was to study how surgical nurses experiences their work order in the operating room (OR), and how they experience their psychosocial work environment and work organization in terms of hierarchical structures..

During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.
