  1. 1. Erlang as an alternative to a non-functional language for communication in a faulttolerant IoT sensor network

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Jimmy Holdö; [2020-02-17]
    Keywords : Internet of Things; Wireless Sensor Network; Erlang; IEEE 802.15.4; ZigBee; Network topology;

    Abstract : This thesis compares a C++ prototype and an Erlang prototype for an Internet ofThings application. Internet of Things applications are difficult to program becausethey consist of a distributed environment of heterogeneous devices, where each devicecan have limited resources and connectivity technologies.

  3. 2. Investigation of the magnetic fields of a young Sun-like star ∏1 UMa

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Lawen Ahmedi; [2020]
    Keywords : Magnetic field; star; young Sun; polarisation; Stokes vector;

    Abstract : In astronomy, the Sun has an important role. It keeps the solar-system together and is thesource for life, heat, light and energy to Earth. As any other star or planet, the Sun has amagnetic field. The magnetic field of the Sun has a great impact on the Sun itself as well asits surrounding. READ MORE

  4. 3. Design of Two 28 GHz Doherty Power Amplifier Topologies with Vertical In(Ga)As Nanowire Transistors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Simon Olson; Lucas Nilsson-Villoresi; [2020]
    Keywords : Doherty; PA; DPA; 28 GHz; Power amplifier; nanowire; transistor; In Ga As; Technology and Engineering;

    Abstract : In this Master’s thesis, two different 28 GHz Doherty power amplifiers (DPAs) are designed, for high power added efficiency (PAE), in the common source (CS) and cascoded topology respectively. The results are analyzed and compared between the two approaches. READ MORE

  5. 4. 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

  6. 5. 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.
