  1. 21. Safe learning for control: Combining disturbance estimation, reachability analysis and reinforcement learning with systematic exploration

    University essay from KTH/Reglerteknik

    Author : Caroline Heidenreich; [2017]
    Keywords : ;

    Abstract : Learning to control an uncertain system is a problem with a plethora ofapplications in various engineering elds. In the majority of practical scenarios,one wishes that the learning process terminates quickly and does not violatesafety limits on key variables. READ MORE

  3. 22. Twisted derivations, quasi-hom-Lie algebras and their quasi-deformations

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Philip Bergander; [2017]
    Keywords : quasi-hom-Lie algebra; hom-Lie algebra; Lie algebra; Twisted derivation; sigma derivation; quasi-Lie algebra; derivation; quasi deformation; quasi-deformation; twisted vector field; polynomial algebra; quotient ring;

    Abstract : Quasi-hom-Lie algebras (qhl-algebras) were introduced by Larsson and Silvestrov (2004) as a generalisation of hom-Lie algebras, which are a deformation of Lie algebras. Lie algebras are defined by an operation called bracket, [·,·], and a three-term Jacobi identity. READ MORE

  4. 23. Hybrid CPU-GPU Parallel Simulations of 3D Front Propagation

    University essay from Linköpings universitet/Hållfasthetslära

    Author : Ezhilmathi Krishnasamy; [2014]
    Keywords : ;

    Abstract : This master thesis studies GPU-enabled parallel implementations of the 3D Parallel Marching Method (PMM). 3D PMM is aimed at solving the non-linear static Jacobi-Hamilton equations, which has real world applications such as in the study of geological foldings, where each layer of the Earth’s crust is considered as a front propagating over time.

  5. 24. On the Distribution and Products of Totatives

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Alma Lindborg; [2014]
    Keywords : Number Theory; Discrete Mathematics; Totatives; Primes; Mathematics and Statistics;

    Abstract : This thesis concerns itself with relative primality of integers. It uses the concept of totatives, that is, integers relatively prime to a fixed number n, to investigate the distribution and products of those integers. READ MORE

  6. 25. Study on optimal train movement for minimum energy consumption

    University essay from Akademin för innovation, design och teknik

    Author : Panagiotis Gkortzas; [2013]
    Keywords : Optimal control; train energy consumption; dynamic programming; Hamilton-Jacobi-Bellman equation;

    Abstract : The presented thesis project is a study on train energy consumption calculation and optimal train driving strategies for minimum energy consumption. This study is divided into three parts; the first part is a proposed model for energy consumption calculation for trains based on driving resistances. READ MORE
