  1. 1. The effect of disorder on the axial anomaly in a lattice model in 1 + 1 dimensions

    University essay from KTH/Fysik

    Author : Agnes Wattrang; [2023]
    Keywords : Axial anomaly; tight-binding model; semiclassical physics; correlated disorder.; Axial kiral anomali; tätbindningsmodell; semiklassisk fysik; korrelerad oordning;

    Abstract : This work investigates the effect of a disorder potential, that represents impurities/dislocations in the lattice, on the time-dependent signature of the axial anomaly in a one-band tight-binding model in one spatial dimension. The tight-binding model is solved numerically and the simulation results are compared with a semiclassical expression for the time-dependent axial density, n5(t), due to Nielsen and Ninomiya [1].

  3. 2. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

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

    Author : Hamish Keay; [2023]
    Keywords : Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Abstract : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. READ MORE

  4. 3. A Performance Comparison of the Single Object Tracking Algorithms ROLO and Tiny-ROLO

    University essay from KTH/Datavetenskap

    Author : Simon Larspers Qvist; Beata Johansson; [2022]
    Keywords : ;

    Abstract : Object tracking in videos is an extension of ordinary object detection, to continuously predict and follow the objects’ path of motion. The Recurrent YOLO (ROLO) algorithm is a two-stage tracking algorithm that utilizes deep neural networks to track objects in image sequences. READ MORE

  5. 4. Graph Bandits : Multi-Armed Bandits with Locality Constraints

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

    Author : Kasper Johansson; [2022]
    Keywords : Multi-armed bandits; locality constraints; reinforcement learning; Flerarmade banditer; lokala restriktioner; förstärkningsinlärning;

    Abstract : Multi-armed bandits (MABs) have been studied extensively in the literature and have applications in a wealth of domains, including recommendation systems, dynamic pricing, and investment management. On the one hand, the current MAB literature largely seems to focus on the setting where each arm is available to play at each time step, and ignores how agents move between the arms. READ MORE

  6. 5. Auditing the Moral Bounds of Al Systems : An Implementation of the Glass-box's Observation Stage

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

    Author : Mauricio Byrd Victorica; [2022]
    Keywords : Artificial intelligence; Ethics; Auditing; Artificiell intelligens; Etik; Revision;

    Abstract : Automated and assisted decision-making has become prevalent across a myriad of domains, often including sensitive and critical tasks where guarantees regarding the operation of artificially intelligent systems from an ethical standpoint become essential. Different parties have made efforts to develop guidelines to establish general ethical requirements these systems should comply with. READ MORE
