  2. 1. Choreographing Flow : A Study in Concrete Deposition

    Author : Helena Westerlind; Hélèna Frichot; Marcelyn Gow; KTH; []
    Keywords : HUMANIORA; HUMANITIES; Architectural Technology; Arkitekturteknik;

    Abstract : The traditional use of concrete in architecture is fundamentally conditioned by the inverse relationship that exists between material and formwork. When poured into a mold, a homogenous mixture takes the shape of its container. More detailed adjustment of the structure of concrete, however, is not possible. READ MORE

  4. 2. Bio-inspired retinal optic flow perception in robotic navigation

    Author : Björnborg Nguyen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; robotic navigation; active fixation; visual perception; bionics; Retinal optic flow fields; gazing; optic flow; retinal flow path;

    Abstract : This thesis concerns the bio-inspired visual perception of motion with emphasis on locomotion targeting robotic systems. By continuously registering moving visual features in the human retina, a sensation of a visual flow cue is created. An interpretation of visual flow cues forms a low-level motion perception more known as retinal optic flow. READ MORE

  5. 3. The role of the hydrological cycle in forest ecosystems : flow path, nutrient cycling and water-carbon interaction

    Author : Yanzi Yan; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; flow path; DOC concentration; groundwater; photosynthesis; Amazon rainforest; catchment geomorphology;

    Abstract : Forest ecosystems, covering over a third of land on the Earth, play a significant role in the global hydrological cycle, and influence soil erosion and climate change. However, the distribution, movements, quality of water, and hydrological processes in forested ecosystems are not well understood yet. READ MORE

  6. 4. Structural Uncertainties of Rock Fractures and their Effect on Flow and Tracer Transport

    Author : Martin Stigsson; Vladimir Cvetkovic; Ki-Bok Min; KTH; []
    Keywords : Fracture; Flow; Transport; Orientation uncertainty; Roughness; Self-affine; Fractal; Shear; Aperture distribution.; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : Att förstå flöde och transport av lösta ämnen genom sprickorna i berggrunden är viktigt för den långsiktiga säkerheten av ett geologiskt slutförvar av farligt avfall. I en diskret spricknätverksmodell byggs flödesvägarna upp av kedjor av flödesvägar genom de enskilda sprickorna i bergmassan. READ MORE

  7. 5. Dynamic Matrix Algorithms and Applications in Convex and Combinatorial Optimization

    Author : Jan van den Brand; Danupon Na Nongkai; Santosh Vempala; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dynamic Algorithm; Data Structure; Optimization; Linear Program; Bipartite Matching; Shortest Path; Maximum Flow; Minimum Cost Flow; Diameter; Computer Science; Datalogi;

    Abstract : Dynamic algorithms are used to efficiently maintain solutions to problems where the input undergoes some changes.This thesis studies dynamic algorithms that maintain solutions to linear algebra problems and we explore their applications and implications for dynamic graphs and optimization problems.
