  1. 1. Linear-scaling Quantum Molecular Dynamics for Reactive Systems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Linnéa Andersson; [2021]
    Keywords : ;

    Abstract : The purpose of this thesis is to demonstrate linear-scaling, energy stable, propagation of the electronic degrees of freedom in finite temperature ExtendedLagrangian Born-Oppenheimer Molecular Dynamics for reactive systems in aself-consistent charge density-functional tight-binding formulation. The inverse Jacobian kernel matrix in the electronic equation of motion is approximated using alow-rank combination of directional derivatives of the ground state residual function. READ MORE

  3. 2. Comparing Different Approaches for Solving Large Scale Power Flow Problems on the CPU and GPU with the Newton-Raphson Method

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Manolo D'Orto; [2020]
    Keywords : ;

    Abstract : Power system modelling is increasing in importance. It is vital for power system operations and transmission grid expansions, and therefore the future energy transition. The Swedish power system is under fast development to face the progress of more flexible demand, a higher share of distributed renewable sources, and updated capacities. READ MORE
