   Author : Simon Wredh; [2020]
   Keywords : computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

   Abstract : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. READ MORE

3. 2. A Comparison of Three Time-stepping Methods for the LLG Equation in Dynamic Micromagnetics

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Simon Wredh; Anton Kroner; Tomas Berg; [2017]
   Keywords : LLG equation; Micromagnetism; Implicit midpoint; Midpoint extrapolation; Projection method;

   Abstract : Micromagnetism is the study of magnetic materials on the microscopic length scale (of nano to micrometers), this scale does not take quantum mechanical effects into account, but is small enough to neglect certain macroscopic effects of magnetism in a material. The Landau-Lifshitz-Gilbert (LLG) equation is used within micromagnetism to determine the time evolution of the magnetisation vector field in a ferromagnetic solid. READ MORE
