  1. 1. Predictive Controllers for Load Transportation in Microgravity Environments

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

    Author : Sujet Phodapol; [2023]
    Keywords : Model Predictive Control; Decentralized control; Multi-robot systems; Space technology; Modell-prediktiv reglering; Decentraliserad reglering; Multirobotsystem; Rymdteknologi;

    Abstract : Space activities have been increasing dramatically in the past decades. As a result, the number of space debris has also increased significantly. Therefore, it is necessary to clean up and remove them to prevent a collision between space debris and spacecraft. READ MORE

  3. 2. Numerical Estimation of Critical Exponents in the 3D XY Model

    University essay from KTH/Fysik

    Author : Christoffer Beiming; [2023]
    Keywords : Theoretical physics; Condensed matter theory; Phase transitions; XY model; Critical exponents; Computational physics; Monte Carlo simulations; Teoretisk fysik; Kondenserade materiens teori; Fasövergångar; XY-modellen; Kritiska exponenter; Beräkningsfysik; Monte Carlo simulering;

    Abstract : The experimentally obtained value of the critical exponent ν is presently in significant disagreement with current theoretical predictions for the λ-universality class. We suggest two novel approaches of determining the exponents ν and η by utilizing the effects of finite size scaling. READ MORE

  4. 3. Numerical Modelling of a Packed Bed Thermal Energy Storage for Applications in a Carnot Battery : KTH Thesis Report

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Gabriel Juul; [2023]
    Keywords : Thermal energy storage; Carnot battery; sand; packed bed; granular medium; porous medium; effective medium technique; effective thermal conductivity; paramedic study; 3D model; COMSOL; numerical modelling; Lagring av värmeenergi; Carnot-batteri; sand; packad bädd; granulärt medium; poröst medium; effektiv mediumteknik; effektiv värmeledningsförmåga; parametrisk studie; 3D-modell; COMSOL; numerisk modellering;

    Abstract : This thesis explores the heat transfer characteristics of a packed bed thermal energy storage device through the development of a 3D model in COMSOL Multiphysics. The model is based on a laboratory-scale device consisting of an aluminum box filled with sand, which acts as the thermal storage medium. READ MORE

  5. 4. Microwave curing of composite material

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Arief Budi Sanjaya; [2023]
    Keywords : microwave curing; cured sample; uncured sample; numerical model; contact heating.; mikrovågshärdning; härdat prov; ohärdat prov; numerisk modell; kontaktuppvärmning.;

    Abstract : Microwave curing has become a trend in composite processing due to its efficiency in energy consumption compared to the traditional curing method. However, as commonly found in every composite processing, controlling the microwave curing process remains challenging. The most feasible control method is to build a numerical model. READ MORE

  6. 5. Dam Failure Analysis of the Parteboda Hydropower Plant : A deterministic approach

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Magnus Simon Graf; [2023]
    Keywords : ;

    Abstract : Despite all the benefits a dam can provide, hundreds of years of experience have shown the destructive forces that can be unleashed by dam failure. To carry out risk management and execute mitigative measures for a dam facility, it is first necessary to assess the incremental consequences of a potential dam failure. READ MORE
