  1. 16. Advanced Ray Tracing Techniques for Simulation of Thermal Radiation in Fluids

    University essay from KTH/Mekanik; KTH/Linné Flow Center, FLOW

    Author : Bernhard Semlitsch; [2010]
    Keywords : Thermal radiation; Solar radiation; Solar energy; Heat transfer;

    Abstract : For modeling thermal heat transfer, not only the effects of convection and conduction are relevant, but also thermal and visible radiation. Radiation is especially important for setups with large temperature differences, as well as for interaction with external light sources. READ MORE

  3. 17. Curvature Maps for Rendering using Enhanced Ambient and Diffuse Illumination

    University essay from Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : Jixi Luo; [2010]
    Keywords : ;

    Abstract : For highly diffuse rendering, some materials like snow are commonly accomplished through the use of simplified local illumination models for ambient and diffuse light. In reality, however, for a given point on a surface, the incident light is not only contributed from directional light sources, but also from backscattering from nearby surfaces. READ MORE

  4. 18. Vertical Displacements in a Medium-rise Timber Building : Limnologen in Växjö, Sweden

    University essay from Institutionen för teknik och design

    Author : Xiong yu Zeng; Su Xin Ren; Sabri Omar; [2009]
    Keywords : Limnologen; Vertical Displacement; Timber Building; Finite Element Analysis; Limnologen; Vertikalförskjutningar; Träkonstruktion; FEM;

    Abstract : Träbyggnandet i Sverige gick in i en ny era när myndigheterna beslutade att upphäva förbudet mot att bygga byggnader som är högre än två våningar. Denna förändring i lagstiftningen har bidragit till att utveckla träbyggandet under det senaste decenniet. READ MORE

  5. 19. Modelling Copper Sources and Fate in Lake Råcksta Träsk, Stockholm : Sediment Copper Content as Indicator of Urban Metal Emissions

    University essay from KTH/Industriell ekologi

    Author : Rajib Sinha; [2009]
    Keywords : copper; source; fate; urban; modelling; lake;

    Abstract : In Stockholm, Sweden, diffuse emissions of metals have become the dominating source of copper towater. This thesis work made an attempt to link the source of copper emission and the fate of the copper in a lake. These models have been applied in the case study of Lake Råcksta Träsk and its urban drainage area in Stockholm, Sweden. READ MORE

  6. 20. Sources of human pathogens in urban waters

    University essay from Sektionen för ekonomi och teknik (SET)

    Author : Mariam Younis Hussein; [2009]
    Keywords : Indicator bacteria; E.coli; enterococci; Giardia; Cryptosporidium; urban wastewater treatment plants; urban stormwater;

    Abstract : The presence of human pathogens in water indicates the sanitary risk associated with different types of water utilization. This study surveyed the sources of human pathogens in urban waters. In order to evaluate the microbiological water quality of urban water, the enumeration of various indicator bacteria (total coliform, fecal coliform, E. READ MORE
