  1. 6. Offshore deployments of marine energy converters

    Författare :Maria Angeliki Chatzigiannakou; Irina Temiz; Mats Leijon; Tony Lewis; Uppsala universitet; []
    Nyckelord :offshore deployments; risk assessment; wave energy converter installation; marine current energy converter installation; economic efficiency; time efficiency; offshore operations; point absorber; hydrodynamic analysis; slack sling criterion; hoisting system failure.;

    Sammanfattning : The depletion warning of non-renewable resources, such as gas, coal and oil, and the imminent effects of climate change turned the attention to clean and fossil fuel-free generated electricity. University research groups worldwide are studying solar, wind, geothermal, biomass and ocean energy harvesting. LÄS MER

  3. 7. Numerical ice sheet modeling : Forward and inverse problems

    Författare :Gong Cheng; Lina von Sydow; Per Lötstedt; Nina Kirchner; Irina Tezaur; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ice sheet modeling; finite element method; grounding line migration; inverse problems; adjoint method; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Ice sheets have strong influence on the climate system. Numerical simulation provides a mathematical tool to study the ice dynamics in the past and to predict their contribution to climate change in the future. Large scale ice sheets behave as incompressible non-Newtonian fluid. LÄS MER

    Sammanfattning : Abstract:My dissertation is taken from an opera singer’s perspective and the aim is three-fold: ·         to investigate and problematize how gender and performance norms are reproduced on the opera stage·         to provide tools and propose approaches to transform gender perspective and norm critique into a creative artistic practice, enabling conscious and active artistic choices in relation to gender and performance norms·         to explore ways to expand the singer's artistic agency. The artistic research project draws on knowledge from both my own practice as a professional opera singer and my collaborators’ experiences from the worlds of opera, classical music and theatre.

  5. 9. Ensembles of Semantic Spaces : On Combining Models of Distributional Semantics with Applications in Healthcare

    Författare :Aron Henriksson; Hercules Dalianis; Martin Duneld; Nigel Collier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; natural language processing; machine learning; distributional semantics; ensemble learning; semantic space ensembles; medical informatics; electronic health records; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Distributional semantics allows models of linguistic meaning to be derived from observations of language use in large amounts of text. By modeling the meaning of words in semantic (vector) space on the basis of co-occurrence information, distributional semantics permits a quantitative interpretation of (relative) word meaning in an unsupervised setting, i.

  7. 10. Modular Hyaluronan-Based Hydrogels for 3D Cell Culture and Bioprinting

    Författare :Michael Jury; Daniel Aili; Robert Selegård; My Hedhammar; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hyaluronan; 3D cell-culture; Biofunctionality; Bioprinting;

    Sammanfattning : Three-dimensional (3D) cell culture facilitates development of biological relevant assays for drug screening and toxicity testing. Compared to conventional 2D cell culture, cells cultured in 3D can more accurately mimic human tissues and organs and thus provide ex vivo data with potentially better predictive value for cancer research, pharmacology, and toxicology, reducing the need for animal models, improving experimental reproducibility, and reducing time and costs in drug development.
