  2. 1. Modelling calving and sliding of Svalbard outlet glaciers : Spatio-temporal changes and interactions

    Author : Dorothée Vallot; Rickard Pettersson; Veijo Pohjola; Ken Mattsson; Tómas Jóhannesson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cryospheric science; glacier modelling; time-lapse imagery; undercutting; sliding inversion; discrete particle model; calving model; subglacial hydrology; sliding law; automatic detection method; calving events size and frequency; ocean interaction; melt water runoff; ice dynamics; ice flow model; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

    Abstract : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. READ MORE

  4. 2. Fuel ion densities and distributions in fusion plasmas : Modeling and analysis for neutron emission spectrometry

    Author : Jacob Eriksson; Göran Ericsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Applied Nuclear Physics; Tillämpad kärnfysik;

    Abstract : Neutrons produced in fusion reactions in a magnetically confined plasma carry information about the distributions and densities of the fuel ions in the plasma. This thesis presents work where various theoretical models of different fuel ion distributions in the plasma are used to calculate modeled components of the neutron energy spectrum. READ MORE

  5. 3. Microresonator combs for coherent optical communications

    Author : Attila Fülöp; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber-optic communication; nonlinear optics; integrated optics devices; four-wave mixing; microresonators;

    Abstract : This thesis covers the study of microresonator-based optical frequency combs for use in coherent optical communication links. Current links typically utilize several free-running lasers to achieve wavelength-division multiplexing (WDM). READ MORE

  6. 4. QCM-D – with focus on biosensing in biomolecular and cellular systems

    Author : Erik Nilebäck; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; QCM-D; biomolecular interactions; cell-surface interaction; glycosaminoglycans; viscoelasticity; cell morphology; Quartz crystal microbalance with dissipation monitoring; surface chemistry; protein conformation;

    Abstract : The high degree of complexity in biological systems is being investigated in greater and greater detail by increasingly sophisticated sensing approaches. The quartz crystal microbalance with dissipation monitoring (QCM-D) technique stands out in this context, by probing the viscoelastic properties at interfaces. READ MORE

  7. 5. Eye-gaze assistive technology for play, communication and learning : Impacts on children and youths with severe motor and communication difficulties and their partners

    Author : Yu-Hsin Hsieh; Helena Hemmingsson; Mats Granlund; Ai-Wen Hwang; Ralf Schlosser; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; communicative interaction; gaze-controlled computer; school learning; participation; severe motor and speech impairments; specialpedagogik; Special Education;

    Abstract : Children and youths with severe motor and communication difficulties experience participation restrictions in varied everyday contexts. Adequate environmental support such as the provision of assistive technology could offer opportunities to enhance their play, learning and interactions with others. READ MORE
