To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.

This thesis has been carried out at the Building and Civil Engineering Programme at Chalmers University of Technology in cooperation with NCC Technology. The study aims to investigate the optimal design of a library of standardized structural solutions for in-house multi-family buildings and what benefits it brings. Today NCC use technology platforms to improve efficiency and simplify the construction process. The platforms provide the constructors guidelines on how construction details should look like, but the details are not complete. NCC Technology started in the spring of 2013 a project to investigate what benefits there are to create a library of standardized structural solutions for the constructors, with more detailed solutions than in the platforms.

Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.

The Gift 2.0 - A Museological Study of donations of Objects and its Underlying Motives, is a study in order to explain why people choose to donate items for museums, rather than any other alternative.The empirical study consists of qualitative, semi-structured research-interviews conducted with seven selected curators from various museums, with extensive experience of the subject acquisition. I have chosen to only examine Swedish cultural-historical museums. The hypothesis that I assumed was first and foremost that the heritage sphere is what Pierre Bourdieu calls a field. The reason that people would donate objects to museums, is that the donation itself brings cultural capital to the donor, from people with the same habitus. Since I felt that Bourdieus theory of field, capital and habitus could not explain all the reason why people donate items to museum, my second hypotheses was that certain objects are what Annette Weiner called inalienable possessions, objects that at any cost may not be sold or bartered away.

A survey was undertaken to understand sheep management, breeding practices and selection criteria for Red Maasai sheep in Maasai pastoralist communities in Kajiado District, Kenya. Differences between North and South Kajiado District were investigated to gain knowledge about farmers having different prerequisites and how it can affect the sheep production. The reason for keeping sheep and the specific breeds show the multiple objectives of the Maasai farmers. Adaptive traits, such as resistance to diseases and droughts, and productive traits, such as increased growth and carcass weight, were both ranked highly. In addition to this, the sheep has a social and traditional value in Maasai culture.

The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.

The theme of my exam project, the practical work and the essay will be the phenomena of dreams. The dreams you have when you are asleep, the dreaming state of mind, places where your mind takes you, when you no longer decide what to think of. It is a fascination about what our mind creates itself. This essay brings up the theme out from seeing the dreams and the unconsciousness as a source of inspiration, both in personal development and from an artistic point of view. How has the world of dreams bin used as inspiration in the art? .

Uppsatsen handlar om konsumenter som producerar produkter som sprids och konsumeras av andra konsumenter. Fenomenet kallas i denna uppsats för konsumentproduktion och jag har inte hittat bra litteratur om ämnet. Dagens allmänt citerade marknadsföringslitteratur som studerats i denna undersökning nämner inte konsumentproduktion som sprids till andra konsumenter. Den litteratur om Open Source som studerats nämner konsumentproduktion, men terminologin för konsumentproduktion är oklar och fokus sätts aldrig på ämnet. Litteraturen i motsats till denna uppsats nämner dessutom bara en mycket speciell och extremare variant av konsumentproduktion som produceras av högt kompetenta programmerare; istället för att som i denna uppsats ge bilden av att även andra konsumenter med andra eller ingen kompetens alls utför konsumentproduktion.

Printed and painted wallpaper on a weaved fabric backing was a common way to decorate homes in Sweden during the eighteenth and nineteenth centuries. Not much is written about the craftsmanship in relation to the hanging of these wallpapers and even less about the conservation of the objects. Even so, many wall segments remain in situ and in museums and are more often than not in dire need of conservation such as deacidification and consolidation. These are composite objects, consisting of cellulose materials with different properties along with adhesives and paints. Analysis of the materials is required to ensure safe handling and choice of conservation materials, and to establish a treatment plan which will be executed in several steps. This thesis aims to identify these steps and develop a method for conserving the wall segments with suitable materials, preferably without altering the source material to any significant degree.

Denna uppsats undersöker möjligheten att använda ett nätverksövervakningssystem för att även övervaka maskindrivna processer. Kan man baka ihop övervakningen av den maskinella processen och datorn som styr maskinen i ett och samma system? Detta genomförs genom att identifiera och implementera ett lämpligt övervakningssystem i en befintlig maskinell laborationsmiljö. Arbetet utvärderas därefter enligt ett antal felscenarion och även utifrån ett systemadministratörsperspektiv. Intervjuer med praktiker inom industribranchen utförs också för att dra ytterligare slutsatser..

A home for elderly is planed to be built at Zakrisdal, Karlstad, Sweden. The heat source for the building was at the time not determined. In order by the local government of Karlstad this report is meant to examine if the need of heat could be provided only by solar heat combined with a seasonal heat storage. The problem to solve is, if the need of heat from the home for elderly is provided from only solar heat, whitch dimensions of the solar collectors and the storage is needed?.

The sun is essential to life on earth and no matter where you are, there is a constant need ofenergy. Nearly 800 000 years ago man learned for the first time to use fire in a controlled way.Since then, fire has given us the opportunity to inhabit places despite a cold climate. In Swedenthe resident sector accounts for a major part of the total consumption of energy. In a time whenenvironmental issues and greenhouse effects are increasing, we also see a future of rising energyprices. With this perspective, we have in this bachelor thesis in the Building Environment at theRoyal Institute of Technology, KTH, in Stockholm decided to focus on the renewable energysource, solar energy.The energy from solar radiation is a free resource and does not have any negative effects uponthe environment.
