  1. 1. AU-led Peace Operations : The Case of the AMISOM KDF’s Local Peacebuilding Engagement in Southern Somalia, Jubbaland Region

    University essay from Linnéuniversitetet/Institutionen för samhällsstudier (SS); Linnéuniversitetet/Institutionen för samhällsstudier (SS)

    Author : Philip Martinsson; Emil Thillberg; [2020]
    Keywords : AU-led Peace Operations; Peacekeeping; Counterinsurgency; Peacebuilding; System-thinking; AMISOM; KDF; Somalia; Jubbaland;

    Abstract : Contemporary peace operations are deployed to increasingly complex, high-risk environments where localised armed groups, often those that can influence the trajectory of the conflict are not at the table, at the same time militaries are mandated to facilitate social, economic and political transformative processes in recovered areas. By the opening of the twenty-first century, the distinction between peacebuilding and military interventions converged both in policy and practice and increasing pressure are placed on the troop contributing countries to adapt to the dynamics of ‘multidimensional peace operations’.

  2. 2. 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. 3. Analysis and Simulation Study of Stochastic Time-To-Collision as a Severity Measure in Traffic Security

    University essay from Lunds universitet/Matematisk statistik

    Author : Per Niklas Benzler Waaler; [2020]
    Keywords : time; collision; ttc; stochastic; probability; transform; transformation; traffic; data; under; estimation; post; encroachment; mixture; distribution; simulation; study; encounter; conflict; trajectory; prediction; road; user; safety; severity; surrogate; measure; Mathematics and Statistics;

    Abstract : Traffic accidents are extremely rare, creating the need for surrogate methods for safety analysis that makes efficient use of the information provided by traffic conflicts, which also are limited in availability. The severity measure time-to-collision (TTC) in combination with extreme value theory have so far been one of the primary measures used to infer traffic safety levels, but it relies on unrealistic assumptions that results in severity measures that do not always agree well with observed danger.

  5. 5. "Stuck in Hel Joseon"

    University essay from Lunds universitet/Sociologi

    Author : Ella Holttinen; [2020]
    Keywords : South Korea; Hel Joseon; millennials; compressed modernity; Confucianism; neoliberalism; human capital; achievement society; Social Sciences;

    Abstract : South Korea is well known for its development miracle: the nation has managed to develop from the state of extreme poverty to the World´s 12th largest economies in a period of five decades. However, the negative consequences and side effects of this rapid growth, and issues of the contemporary Korean society has been less discussed, especially from the perspective of the Korean youth.
