  1. 1. Vehicle dynamics modelling of electromagnetic suspensions for MAGLEV applications

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Léa Chatelais; [2024]
    Keywords : MAGLEV; Dynamics; Requirements; Suspension; Vehicle modeling; MATLAB; MAGLEV; Dynamisk; Fordran; Upphängning; Fordon modell; MATLAB;

    Abstract : MAGnetic LEVitation Guidance System (MAGLEV) technology was commercially introduced relatively recently in the guided transport field. It is based on removing the wheels and rails of classic railway systems and supporting and guiding the train with magnets and magnetic forces instead. READ MORE

  3. 2. Machine Learning model applied to Reactor Dynamics

    University essay from KTH/Fysik

    Author : Dionysios Dimitrios Nikitopoulos; [2023]
    Keywords : Master Thesis; Machine Learning; stability; Energy distribution profiles; Prediction; frequency; decay ratio; Data processing; POLCA-T; Pytorch; testing data; RMSE. ii;

    Abstract : This project’s idea revolved around utilizing the most recent techniques in MachineLearning, Neural Networks, and Data processing to construct a model to be used asa tool to determine stability during core design work. This goal will be achieved bycollecting distribution profiles describing the core state from different steady statesin five burn-up cycles in a reactor to serve as the dataset for training the model.

  4. 3. Pulse-width voltage modulation in the Python-based open-source simulator Motulator : A Realization of SVPWM, Harmonic analyzer and Over-modulation on Two and Three-level Inverters, and a Solution for Unbalanced Neutral Point Voltage on Three-level Inverters

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

    Author : Jiale Deng; [2023]
    Keywords : Three-level inverters; over-modulation techniques; space vector modulation; neutral-point voltage balancing; non-uniform Fourier transform; Trenivåväxelriktare; övermodulation; spacevektormodulering; balansering av nollpunktsspänning; olikformig Fouriertransform;

    Abstract : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. READ MORE

  5. 4. Governance and decision-making : Lessons from three French eco-villages

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Gwenaël Bertrand; [2023]
    Keywords : ;

    Abstract : In a context of rising environmental pressure and slow societal changes in response, the emergence of ecovillages comes as a small-scale solution to actively propose sustainable alternatives to the modern consumerist society. The human factor plays a key role in enabling such ecovillages to last. READ MORE

  6. 5. Dynamic Power Systems Modeling: Power Plant Types, Demand, and Environmental Impacts

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

    Author : Alexandra Papadopoulos; Linn Ekman; [2023]
    Keywords : ;

    Abstract : It is increasingly important to understand the dynamics of power systems. Most notably, thetransition towards renewable energy sources will radically change the way our power systemworks. A better understanding of the system dynamics is crucial to smoothly transitiontoward a sustainable system without undesirable side effects. READ MORE
