  1. 11. Site Application of a Channel Network Model for Groundwater Flow and Transport in Crystalline Rock

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Jonas Pedersen; [2018]
    Keywords : channel network models; discrete fracture networks; model calibration; groundwater flow and transport;

    Abstract : Groundwater flow and transport in deep crystalline rock is an important area of research. This is partly due to its relevance for constructing a long term repository for storing radioactive spent nuclear fuel in deep bedrock. READ MORE

  3. 12. Real-time screen space reflections and refractions using sparse voxel octrees

    University essay from Lunds universitet/Institutionen för datavetenskap

    Author : Filip Nilsson; [2015]
    Keywords : Sparse octree; voxel; ray tracer; reflection; refraction; Technology and Engineering;

    Abstract : This thesis explores the data structure known as sparse voxel octree and how it can improve the performance of real-time ray tracing. While ray tracing is an excellent way of producing realistic effects in computer graphics it is also very computationally heavy. READ MORE

  4. 13. Analysis of human exposure at local exhaust ventilation by means of 3D air velocity measurements, tracer gas tests and controlled turbulence environment

    University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Author : Leyre Catalan Ros; [2015]
    Keywords : local exhaust ventilation; human exposure;

    Abstract : Local exhaust (LE) ventilation is a ventilation technique where contaminated air is locally extracted close to the contaminant source usually with the purpose to reduce the exposure of workers to dust, fumes or vapour, which can be hazardous to their health. The performance of a LE installation depends however on many influential factors, and there is not yet an international standardized way to test LE constructions. READ MORE
