  1. 1. Classification of Flying Qualities with Machine Learning Methods

    University essay from KTH/Flygdynamik

    Author : Ola Isaksson; [2021]
    Keywords : Flying Qualities; Machine Learning; Flight Mechanics; Flygkvaliteter; Maskininlärning; Flygmekanik;

    Abstract : The primary objective of this thesis is to evaluate the prospect of machine learning methods being used to classify flying qualities based on simulator data (with the focus being on pitch maneuvers). If critical flying qualities could be identified earlier in the verification process, they can be further invested in and focused on with less cost for design changes of the flight control system.

  2. 2. Black-box optimization of simulated light extraction efficiency from quantum dots in pyramidal gallium nitride structures

    University essay from Linköpings universitet/Matematiska institutionen

    Author : Karl-Johan Olofsson; [2019]
    Keywords : Black-box optimization; Radial basis functions; Gallium nitride; light extraction efficiency; FDTD; surrogate functions; semiconductors; global optimization;

    Abstract : Microsized hexagonal gallium nitride pyramids show promise as next generation Light Emitting Diodes (LEDs) due to certain quantum properties within the pyramids. One metric for evaluating the efficiency of a LED device is by studying its Light Extraction Efficiency (LEE). READ MORE

  3. 3. Mesh Morphing Technique used with Open-Source CFD Toolbox in Multidisciplinary Design Optimisation

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Rok Lapuh; [2018]
    Keywords : ;

    Abstract : Nowadays, the product design process relies on computer simulations more than ever. Compared to the experimental tests, they allow substantially more designs to be evaluated. Moreover, computer simulations allow a search for the optimum. That is why a fast and efficient transition from one design iteration to the next is necessary. READ MORE

  4. 4. Robust Design and Analysis of Automotive Collision Avoidance

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Anders Sjöberg; [2017-02-10]
    Keywords : Simulation-based optimization; response surface methodology; radial basis functions; multi-objective optimization; Pareto optimal solutions; trigger edge; tunable parameters; false intervention; robustness; positive and negative performance scenarios.;

    Abstract : Automotive collision avoidance systems help the driver to avoid or mitigate a collision. The main objective of this project is to find a methodology to improve the performance of Volvo's automotive collision avoidance system by optimizing its configurable parameters. READ MORE

  5. 5. Stencil Study for RBF-FD in Option Pricing

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Robin Eriksson; [2016]
    Keywords : RBF-FD; Option pricing;

    Abstract : This thesis contains results on convergence studies for different stencils of radial basis function generated finite difference (RBF-FD) method applied to solving Black-Scholes equation for pricing European call options. The results experimentally confirm the theoretical convergence rates for smooth payoff functions with stencils of size 3, 5 and 7 in one- dimensional problems, and 9, 13 and 25 in two- dimensional problems.
