  1. 1. Ice Formwork : The Rationale and Potential of Ice-Based Moulding Systems  for the Production of Complex-Geometry  Precast Concrete

    Author : Vasily Sitnikov; Oliver Tessmann; Tim Ainsworth Anstey; Harald Kloft; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ice Formwork; High-Performance Concrete; Digital Fabrication; Refrigeration; Embodied Energy; Grey energy; Carbon Footprint.; Architectural Technology; Arkitekturteknik;

    Abstract : This doctoral thesis analyses and makes proposals about adapting the poten-tial of digital means of production to the needs of the concrete industry. More precisely, it aims at fostering the development of sustainable material cycles and the innovation in manufacturing methods in the field of architectural and structural design of ultra-high performance fibre-reinforced concrete (UHPFRC).

  2. 2. Breaking the ice : effects of ice formation and winter floods on vegetation along streams

    Author : Lovisa Lind; Christer Nilsson; Christine Weber; Michael Scott; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; anchor ice; climate change; in-stream; riparian; river ice; streams; vegetation;

    Abstract : Streams in cold regions are characterized by unique hydrological processes that control flow regime and water levels. One of the most important processes is the formation, growth and melting of different types of ice in and around the stream channel during winter. READ MORE

  3. 3. Palaeo-ice streams in the north-eastern Laurentide Ice Sheet

    Author : Hernán De Angelis; Johan Kleman; Krister Jansson; Colm O'Cofaigh; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ice sheet; ice stream; palaeo-ice sheet; palaeo-ice stream; glaciology; palaeoglaciology; Laurentide Ice Sheet; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Physical Geography;

    Abstract : This thesis presents a palaeoglaciological study aimed to determine the location, geometry and temporal evolution of palaeo-ice streams of the north-easternmost Laurentide Ice Sheet. The work was accomplished through the geomorphological interpretation of satellite imagery over 3. READ MORE

  4. 4. Ridged sea ice modelling in climate applications

    Author : Sebastian Mårtensson; Markus Meier; Kristofer Döös; Peter A. Lundberg; Frank Kauker; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arctic ocean; Baltic Sea; sea ice; ice dynamics; numerical modelling; climate; ice deformation; ice compression; physical and biogeochemical interactions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : This work aims to increase our understanding of the nature of large scale features of sea ice from a dynamics point of view.Sea ice plays an important part in the exchange of heat and humidity between sea and air and thus is an important component of the climate system. READ MORE

  5. 5. Ice load prediction for design of ice-going ships for inland waterways

    Author : Meng Zhang; Karl Garme; Magnus Burman; Malin Åkermo; Pentti Kujala; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inland waterway ship; ice load; ice conditions; ice properties; FSICR; probabilistic method; ice-hull interaction; numerical model; structural response; finite element analysis; Teknisk mekanik; Engineering Mechanics;

    Abstract : With increasing interest in utilizing the inland waterways (IWW) in European countries, the design of IWW vessels gains attention both from a transport efficiency and an emission control point of view. However, unlike in western and central European countries, in Nordic countries, e.g. READ MORE
