    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Efficiency factors of space heating; hydronic panel radiator; hydronic floor heating; multilayer wall; numerical modelling; room control volume; decrement factor; time delay; heat conduction; heat convection; heat radiation; heat storage; thermal inertia; Euler solver; Newton-Raphson method; synthetic weather file; feedback and feed-forward control strategies; adaptive control; validation methodology; uncertainty bands; robustness of model predictions; thermostatic booth simulator; differential sensitivity analysis; transient model of panel radiator with multiple storage elements; active thermal mass; benchmark performance indicator; linear regression model; calibration through uncertainty bands; hybrid model of low-energy building: law driven data driven; outdoor temperature compensation heating curve; solar radiation model; finite difference method; heat equation;

    Abstract : The thesis focuses on the efficiency of the space heating system. In particular, the efficiency factors measure the efficiency of thermal zone. The efficiency factors measures how the energy is used in a space heating. READ MORE

  2. 2. Community Robustness Analysis Theoretical Approaches to Identifying Keystone Structures in Ecological Communities

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Sofia Berg; Linköpings universitet.; Linköpings universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Most of the world’s ecosystems suffer from stress caused by human activities such as habitat destruction, fragmentation, overexploitation of species and climate change. These factors affect the reproduction and/or survival of individual species as well as interactions between species in ecological communities. READ MORE

  3. 3. On Parameter Identification for Better Predictions of Dam Behaviour

    University dissertation from Luleå : Luleå University of Technology

    Author : Jasmina Toromanovic; Luleå tekniska universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Numerical modelling is often needed as a tool to predict the behaviour and assess the safety of dam structures. Embankment dam structures analyses are quite complex and potential failures are hazardous. Predictions of dam behaviour by numerical modelling rely on knowledge about the mechanical properties of the materials the dam is constructed with. READ MORE

  4. 4. Modelling of the cyclic behaviour of superalloys

    University dissertation from Luleå : Luleå University of Technology

    Author : Rebecka Brommesson; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FEM; kinematic hardening; Cyclic plasticity; TMF; superalloy;

    Abstract : In the aviation industry today there is a trend of increasing operating temperatures in turbine engines. The advantages with higher temperatures in the engines are improved performance and efficiency. READ MORE

  5. 5. Tracking the Wanders of Nature

    University dissertation from Linköping : Linköping University Electronic Press
