  1. 11. Hydrodynamic control of retention in heterogeneous aquifers and fractured rock

    Author : Hua Cheng; Vladimir Cvetkovic; Chin-Fu Tsang; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer; Fracture; groundwater; First-order solution; Monte-Carlo simulation; Nu-clear waste; Heterogeneity; Retention processes; Matrix diffusion; Prediction; Evaluation; Travel time; Flow rate; ; Water engineering; Vattenteknik;

    Abstract : In this thesis, fluid flow and solute transport in heterogeneous aquifers and particularly in frac-tured rock have been investigated using Lagrangian Stochastic Advective-Reaction (LaSAR) framework. The heterogeneity of the aquifer structure or fracture configuration, as well as the various reaction/retention processes have been considered in the modelling approach. READ MORE

  2. 12. Coding of Three-dimensional Video Content : Diffusion-based Coding of Depth Images and Displacement Intra-Coding of Plenoptic Contents

    Author : Yun Li; Mårten Sjöström; Ulf Jennehag; Roger Olsson; Touradj Ebrahimi; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In recent years, the three-dimensional (3D) movie industry has reaped massive commercial success in the theaters. With the advancement of display technologies, more experienced capturing and generation of 3D contents, TV broadcasting, movies, and games in 3D have entered home entertainment, and it is likely that 3D applications will play an important role in many aspects of people's life in a not distant future.

  3. 13. Coding of three-dimensional video content : Depth image coding by diffusion

    Author : Yun Li; Mårten Sjöström; Ulf Jennehag; Roger Olsson; Markus Flierl; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Three-dimensional (3D) movies in theaters have become a massive commercial success during recent years, and it is likely that, with the advancement of display technologies and the production of 3D contents, TV broadcasting in 3D will play an important role in home entertainments in the not too distant future. 3D video contents contain at least two views from different perspectives for the left and the right eye of viewers.

  4. 14. Evaluation of Dust Suppressants for Gravel Roads : Methods Development and Efficiency Studies

    Author : Karin Edvardsson; Björn Birgisson; Andrew Dawson; KTH; []
    Keywords : Gravel road; dust; particulate matter; PM10; horizontal dust diffusion; deteriorations; maintenance; dust control; dust suppressants; efficiency; application rate; leaching; residual concentration; seasonal variations; salt solution; solid salt; calcium chloride; magnesium chloride; lignosulphonate; polysaccharide sugar ; bitumen emulsion; rape oil; starch; surfactant; mesa; clay; fine material content;

    Abstract : Approximately 75 percent (300 000 km) of the total Swedish road network and 20 percent(20 000 km) of the national road network consists of gravel roads. One of the most significantproblems associated with gravel roads is traffic-generated dust emission, which contributes tothe deterioration of the road surface and acts as a major source of particulate matter releasedinto the atmosphere, thereby involving public economics, road safety, human health, andenvironmental quality.

  5. 15. Reclamation of acid-generating waste rock by in-pit backfilling and sealing : An evaluation of the Kimheden mine site, northern Sweden

    Author : Lucile Villain; Bernhard Dold; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : The notion of mine site reclamation is very recent compared to the history of mining. In thepast, mine sites were left as is following termination of the operations, but modern regulationsrequire anticipation of long-term contamination of the surrounding environment and return ofthe land to a sustainable use.
