  1. 1. Experiments and Predictions of Heat Transfer Characteristics in Circulating Fluidized Bed Boilders

    Author : Mohammad Golriz; Chalmers University of Technology; []
    Keywords : heat transfer coefficient; circulating fluidized bed; membrane wall; boilers; thermal boundary layer; predictions; experiments;

    Abstract : This thesis presents experiments and predictions of heat transfer characteristics in circulating fluidized bed boilers. The boiler used for the experiments has a maximum load of 12 MWth, and the dimensions of the combustion chamber are 1.4 m x 1.7 m x 1 3. READ MORE

  2. 2. Making predictions using χEFT

    Author : Boris Karlsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NN scattering; few-nucleon physics; nuclear physics; χEFT; uncertainty quantification;

    Abstract : In this thesis we explore the merits of chiral effective field theory (χEFT) as a model for low-energy nuclear physics. χEFT is an effective field theory based on quantum chromo dynamics (QCD) describing low-energy interactions of nucleons and pions. READ MORE

    Abstract : Organic solar cells employing fullerenes blended with conjugated polymers as the main light-absorbing material have achieved power conversion efficiencies exceeding 10%. They hold promise as an alternative energy source with many advantages in terms of long-term sustainability and reduced greenhouse gas emissions. READ MORE

  5. 5. Space Weather Physics: Dynamic Neural Network Studies of Solar Wind-Magnetosphere Coupling

    Author : Jian-Guo Wu; Astronomi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geophysics; kosmisk kemi; rymdvetenskap; Astronomi; cosmic chemistry; solar wind; space weather; magnetosphere; solar wind-magnetosphere coupling; geomagnetic activity; geomagnetic storms; predictions; modeling; neural networks; space research; Astronomy; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; Fysicumarkivet A:1997:Wu;

    Abstract : This thesis presents studies of solar wind-magnetosphere coupling using dynamic neural networks in combination with statistically correlative analysis. The primary contribution of the thesis is dynamic neural network models that can be implemented for near real-time predictions of geomagnetic storms from the solar wind alone. READ MORE
