  1. 1. A Study of the Loss Landscape and Metastability in Graph Convolutional Neural Networks

    University essay from KTH/Matematisk statistik

    Author : Sofia Larsson; [2020]
    Keywords : Graph neural networks; Graph convolutional neural networks; Loss landscape; Gradient descent; Stochastic gradient descent; Stochastic gradient Langevin dynamics; Grafneurala nätverk; grafiska faltningsnätverk; lösningslandskap; gradientmetoder; stokastiska gradientmetoder; stokastisk gradient Langevin dynamik;

    Abstract : Many novel graph neural network models have reported an impressive performance on benchmark dataset, but the theory behind these networks is still being developed. In this thesis, we study the trajectory of Gradient descent (GD) and Stochastic gradient descent (SGD) in the loss landscape of Graph neural networks by replicating Xing et al. READ MORE

  3. 2. Evaluating Topology Optimization as an alternative methodology for developing Vibration Test Fixtures

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Jenny Helene Bolle; [2020]
    Keywords : Topology Optimization; Vibration test fixtures; Additive Manufacturing;

    Abstract : This thesis evaluates an alternative method for creating vibration test fixtures. The new method is based on producing fixtures by utilizing the external forces, that a fixture is subjected to during vibration tests, instead of creating it with estimations and guess-work, as it is done today.

  4. 3. A study on topology optimization and cost estimation of fused depostion modelling parts

    University essay from Högskolan i Halmstad/Rydberglaboratoriet för tillämpad naturvetenskap (RLAS); Högskolan i Halmstad/Rydberglaboratoriet för tillämpad naturvetenskap (RLAS)

    Author : prince charuvila thekkethil simon; jibin joseph john; [2020]
    Keywords : ;

    Abstract : Additive manufacturing (AM) is acquiring a lot of importance in the manufacturing field. It makes the whole manufacturing process easier and effectively brings down the manufacturing cost compared to the traditional methods. It also provides the manufacturer with the freedom of customization according to each customer. READ MORE

  5. 4. Design Space Exploration for Structural Aircraft Components : A method for using topology optimization in concept development

    University essay from Linköpings universitet/Maskinkonstruktion

    Author : Sofia Schön; [2019]
    Keywords : Design Space Exploration; Topology Optimization; Knowledge Based Engineering; Model Based Design;

    Abstract : When building aircrafts, structural components must be designed for high strength, low cost, and easy assembly.To meet these conditions structural components are often based upon previous designs, even if a new component is developed. READ MORE

  6. 5. Topology optimization for distributed consensus in multi-agent networks

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

    Author : Johan Niklasson; Oskar Hahr; [2019]
    Keywords : Multi-agent networks; Distributed systems; Wireless Sensor Network; Consensus averaging; Unmanned Aerial Vehicle; Graph-Theory.; Multiagent-nätverk; Distribuerade system; Trådlösa sensornätverk; Konsensusvärde; Drönare; Grafteori.;

    Abstract : Distributed networks, meaning a network in which several agents work together unanimously to perform some task in order to reach goals has become a field with a wide range of applications. One such applications may exist in the form of drones with a purpose of observing and detecting forest fires. READ MORE
