11. Linear-scaling Quantum Molecular Dynamics for Reactive Systems
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : 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

12. Accelerating bulk material property prediction using machine learning potentials for molecular dynamics : predicting physical properties of bulk Aluminium and Silicon
University essay from Linköpings universitet/Teoretisk FysikAbstract : In this project machine learning (ML) interatomic potentials are trained and used in molecular dynamics (MD) simulations to predict the physical properties of total energy, mean squared displacement (MSD) and specific heat capacity for systems of bulk Aluminium and Silicon. The interatomic potentials investigated are potentials trained using the ML models kernel ridge regression (KRR) and moment tensor potentials (MTPs). READ MORE

13. A Topology-Based Method for Inferring Turbulence in Unsteady Flows
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Understanding the rise and evolution of turbulence is an important component of designing vehicles and turbomachinery that both have long life and are efficient. To this end, researchers study the complex phenomenon of turbulence. READ MORE

14. Kernel density estimators as a tool for atmospheric dispersion models
University essay from Umeå universitet/Institutionen för fysikAbstract : Lagrangian particle models are useful for modelling pollutants in the atmosphere. They simulate the spread of pollutants by modelling trajectories of individual particles. However, to be useful, these models require a density estimate. The standard method to use has been boxcounting, but kernel density estimator (KDE) is an alternative. READ MORE

15. Applying Generative Adversarial Networks for the Generation of Adversarial Attacks Against Continuous Authentication
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Cybersecurity has been a hot topic over the past decades with lots of approaches being proposed to secure our private information. One of the emerging approaches in security is continuous authentication, in which the computer system is authenticating the user by monitoring the user behavior during the login session. READ MORE
