  1. 1. Analysis of a shape morphing structural battery: manufacturing, analytical modeling and numerical simulation

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

    Author : Alfredo Bici; [2023]
    Keywords : ;

    Abstract : A reduction in the global use of fossil fuels is necessary when striving for a more sustainable future. One key strategy in the transition from fossil fuels is electrification. This strategy is particularly prominent within the transport sector, where more efficient ways to store electric energy are being pursued. READ MORE

  3. 2. Improving Visibility Forecasts in Denmark Using Machine Learning Post-processing

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : August Thomasson; [2023]
    Keywords : visibility forecast; fog; machine learning; numerical weather predicition; XGBoost; Random Forest; siktprognos; dimma; maskininlärning; numerisk vädermodell; XGBoost; Random Forest;

    Abstract : Accurate fog prediction is an important task facing forecast centers since low visibility can affect anthropogenic systems, such as aviation. Therefore, this study investigates the use of Machine Learning classification algorithms for post-processing the output of the Danish Meteorological Institute’s operational Numerical Weather Prediction (NWP) model to improve visibility prediction.

  4. 3. Numerical analysis of a bearing strength in delaminated composite joint

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

    Author : Olavi Kukkonen; [2023]
    Keywords : Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

    Abstract : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.

  5. 4. 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
