1. Models of the Universe : An analysis of the asymptotic behaviour of non-linear dynamical systems
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : In this thesis we present some relevant theory, and then we rigorously investigate the existence intervals and the asymptotic behaviors of three cosmological models. The first model we investigate is based on the Friedmann-Lemaître-Robertson-Walker (FLRW) metric, which is consistent with the cosmological principle. LÄS MER
2. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och systemSammanfattning : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. LÄS MER
3. Reduced Order Modelling using Dynamic Mode Decomposition and Koopman Spectral Analysis with Deep Learning
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : In the industry simulation models are commonly used in system development. These models can become complicated in order to capture the physical behaviour of the underlying dynamical system. A high-fidelity representation, which can result in long simulation times, is in some settings not strictly required. LÄS MER
4. Sensor fusion and fault diagnosticsin non-linear dynamical systems.
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknikSammanfattning : Sensors are highly essential components in most modern control systems and are used in increasingly complex ways to improve system precision and reliability. Since they are generally susceptible to faults it is common to perform on-line fault diagnostics on sensor data to verify nominal behavior. LÄS MER
5. Optimal consensus and opinion dynamics
Master-uppsats, KTH/Optimeringslära och systemteoriSammanfattning : In the following thesis we study the influence of the communication graph on the behavior of multi-agent systems. Specifically we investigate two issues the first is concerned with the existence of consensus control for linear dynamics, the second is a study of the behavior of a nonlinear dynamical related to opinion dynamics.
