  1. 1. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Emelie Zhu; [2024]
    Keywords : Physics and Astronomy; Technology and Engineering;

    Abstract : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. READ MORE

  2. 2. Interpreting Mental Rotation Performance in Self-Described Aphantasia through Cognitive Penetrability

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Dániel Pénzes; [2023]
    Keywords : mental imagery debate; cognitive penetrability; aphantasia; VVIQ; OSIQ; mental rotation;

    Abstract : Mental images are unique mental representations and the depictive view in the imagery debate states that mental images have similar spatial structures as their corresponding external object. The propositional view, however, contends that beliefs about the external world influence a mental image – also known as the cognitive penetrability theory –, therefore mental images cannot be described in visual terms.

  3. 3. Causal Reinforcement Learning for Bandits with Unobserved Confounders

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Mingwei Deng; [2023]
    Keywords : ;

    Abstract : Reinforcement Learning (RL) has been recognized as a valuable tool in various fields. However, its application is limited by its reliance on extensive data through a trial-and-error approach and challenges in generalizing learned policies. READ MORE

  4. 4. Rapidly-Exploring Random Trees for real-time combined Exploration andPath Planning

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Kalle Löfgren; [2023]
    Keywords : Robotics; RRT; ERRT; Exploration; Autonomous exploration; path planning; goal generation;

    Abstract : The use of micro aerial vehicles (MAV) for civilian use such as exploration and inspection of varying structures, equipment and areas have garnered some interest as of late. MAVs have the mobility and agility to traverse three dimensional space quickly and access hard to reach areas where other alternatives would struggle, but a flying platform such as a MAV comes with it’s own set of distinct problems.

  5. 5. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    University essay from KTH/Tillämpad fysik

    Author : Alexandros Bampis; [2023]
    Keywords : Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Abstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE
