  2. 16. Divisive connections: Theory and tools for the quantification of barrier effects in transport infrastructure projects

    Author : Job van Eldijk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impact assessment; decision support; transport infrastructure; barrier effects; severance;

    Abstract : Transport infrastructure increases regional accessibility but at the same time it creates barriers that reduce local accessibility. These barriers reduce social contacts between people, and limit access to services and leisure. READ MORE

  4. 17. Ecology, Transport Infrastructure and Environmental Assessment

    Author : Mårten Karlson; Berit Balfors; Ulla Mörtberg; Andreas Seiler; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; EIA; SEA; Transport Infrastructure; Ecology; Biodiversity;

    Abstract : Transport infrastructure has a wide array of effects on ecological processes. These effects benefit certain species and might enhance or accelerate ecological processes such as colonization and dispersal, but as well extinction. READ MORE

  5. 18. Water erosion modeling using fractal rainfall disaggregation- a study in semiarid Tunisia

    Author : Sihem Jebari; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reservoir siltation; regionalization; fractal analysis; Atlasic mountain range; erosive events; semiarid area; soil loss; Tunisia.; Soil erosion; semiarid; Tunisia; rainfall; fractal; diaggregation;

    Abstract : In the Tunisian semiarid area, water erosion processes have led to negative economic and environmental consequences in a context of limited water resources. To characterize and predict these degradation phenomena, a comprehensive high-resolution data base on erosive rainfall, together with siltation records for 28 small reservoirs were analyzed.

  6. 19. Understanding Human Mobility with Emerging Data Sources: Validation, spatiotemporal patterns, and transport modal disparity

    Author : Yuan Liao; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; travel mode; data mining; travel time; mobility; social media data; gravity model; Twitter; geographical information systems;

    Abstract : Human mobility refers to the geographic displacement of human beings, seen as individuals or groups, in space and time. The understanding of mobility has broad relevance, e.g., how fast epidemics spread globally. READ MORE

  7. 20. Seascape Dialogues : Human-sea interaction in the Aegean from Late Neolithic to Late Bronze Age

    Author : Christopher Nuttall; Michael Lindblom; Gunnel Ekroth; Matthew Haysom; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Seascapes; Aegean prehistory; Greece; material culture; Classical Archaeology and Ancient History; Antikens kultur och samhällsliv;

    Abstract : This thesis examines human-sea interaction based on embodied and embedded action in the littoral and island regions of the Aegean from Late Neolithic (4800 BCE) to the end of Late Bronze Age I (1600 BCE). Fundamental to this approach is the concept of seascapes, defined here as a place or agent created by a human mind set. READ MORE
