  1. 1. Continuing peace amidst changing contexts : A Sinn Féin case study on institutional resilience

    University essay from Linnéuniversitetet/Institutionen för samhällsstudier (SS)

    Author : Märta-Stina Lindqvist Käll; [2019]
    Keywords : Institutional resilience; Northern Ireland; Sinn Féin; IRA; sustainable peace building; rebel to party transformation; peace continuation; Brexit;

    Abstract : The transitioning of armed actors into political parties following a peace accord is not a new phenomenon and the debate for how we can facilitate such a transition is well explored. A grey area of the debate, however, concerns transitioned actors’ long-term commitment to peace, as relapses are known to have occurred on many occasions. READ MORE

  2. 2. Using Reinforcement Learning for Games with Nondeterministic State Transitions

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Max Fischer; [2019]
    Keywords : reinforcement learning; proximal policy optimization; PPO; machine learning; artificial intelligence; deep learning; neural network; candy crush; mobile game;

    Abstract : Given the recent advances within a subfield of machine learning called reinforcement learning, several papers have shown that it is possible to create self-learning digital agents, agents that take actions and pursue strategies in complex environments without any prior knowledge. This thesis investigates the performance of the state-of-the-art reinforcement learning algorithm proximal policy optimization, when trained on a task with nondeterministic state transitions.

  3. 3. Mechanical and Thermal Characterisation of Novel UHMWPE Composites for Total Joint Arthroplasty

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

    Author : Julian Somberg; [2019]
    Keywords : UHMWPE; Nanocomposites; DSC; Fracture Toughness; Wear;

    Abstract : Total joint arthroplasty surgeries are known to have a high success rate but the longevity of the implants still acts as a limiting factor. Ultrahigh molecular weight polyethylene is the material of choice for the implant bearing surfaces due to its excellent clinical and tribological performance. READ MORE

  4. 4. Sustainable urban districts: Identifying success factors and their (potential) implications for the transformation of Sege Park, Malmö

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Amelie Johansson; [2019]
    Keywords : Sustainable Development; Transition Management; transition experiment; urban; district; Sege Park; brownfield;

    Abstract : This thesis identifies factors for success and un-success in European sustainable urban development projects and subsequently aims to correlate them with the characteristics and practices of an on-going project, concluding in a set of policy recommendations. Worldwide urbanisation brings a concentration of activities contributing to environmental degradation and social injustice, which implies the need for implementing sustainable development practices in urban planning.

  5. 5. Nonequilibrium gauge field in Two Particle Irreducible real time formalism

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik; Lunds universitet/Teoretisk partikelfysik

    Author : Rasmus Hansen; [2019]
    Keywords : Gauge field; non-equilibrium; quantum field theory; Physics and Astronomy;

    Abstract : The purpose of this thesis is to study what effect a photon field has on the equations of motion and the decay of a charged scalar field in thermal equilibrium at finite temperature and outside of thermal equilibrium. To do this we calculate the two-particle irreducible effective action for the mean fields and propagators and derive their equations of motion. READ MORE
