16. Solar integrated heating systems: Applications in buildings and industries
Abstract : “Heat is half” of the global final energy consumption, and the decarbonization of the heating sector is critical to achieving climate goals. This thesis employs a system modelling approach to evaluate renewable heating systems. READ MORE

17. Models for coupled active-passive population dynamics : Mathematical analysis and simulation
Abstract : In this dissertation, we study models for coupled active--passive pedestrian dynamics from mathematical analysis and simulation perspectives. The general aim is to contribute to a better understanding of complex pedestrian flows. READ MORE

18. Simulation of Chemical Reactors
Abstract : This thesis consists basically of two parts. They are, however, interrelated by the fact that both parts concerns modelling of catalytic reaction systems and also by the fact that in both parts, spectral methods are used for simulation. The first part describes the numerical treatment of the dispersion model. READ MORE

19. Uncertainty quantification for wave propagation and flow problems with random data
Abstract : In this thesis we study partial differential equations with random inputs. The effects that different boundary conditions with random data and uncertain geometries have on the solution are analyzed. Further, comparisons and couplings between different uncertainty quantification methods are performed. READ MORE

20. On the solidification of Al alloys during microgravity
Abstract : Thermal analyses have been performed on Al, Al-Cu alloys,Al-Sn alloys, Pb, Sn, Pb-Sn alloys and Al-based amorphousalloys were also investigated. The cooling rates varied fromless than a Kelvin per minute to more than 10,000 Kelvin persecond. Solidification was made under normal gravity and undermicrogravity conditions. READ MORE
