  1. 1. Development of a Nordic BWR plant model in APROS and design of a power controller using the control rods

    University essay from KTH/Fysik

    Author : Jonathan Al-Ani; [2021]
    Keywords : APROS; Dynamic process simulation; System code; Nuclear reactor; nuclear power; BWR; Boiling Water Reactor; closed cycle; steam cycle; one-dimensional flow; Westinghouse; control rods; APROS; Dynamisk processimulering; Beräkningsmodell; Kärnkraft; BWR; Kokvattenreaktor; ångcykel; en-dimensionell flödesmodell; Westinghouse; kontrollstavar;

    Abstract : In this master thesis an input-model of a Nordic BWR power plant has been developed in APROS. The plant model contains key systems and major thermohydraulic components of the steam cycle, including I&C systems (i.e. power, pressure, level and flow controls). READ MORE

  2. 2. 2D & 3D phase retrieval for propagation-based X-ray phase-contrast tomography

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

    Author : Philip Stjärneblad; [2021]
    Keywords : Propagation-based X-ray phase-contrast tomography; PB-PCT; Propagation-based X-ray phase-contrast Imaging; PB-PCI; 2d phase retrieval; 3d phase retrieval; TIE; sinogram consistency; reconstruction artefacts; Science General;

    Abstract : Propagation-based X-ray phase-contrast tomography is a 3d imaging technique that utilizes two-dimensional projections from different angular views $\theta =[0,\pi]$ to reconstruct the 3D object information. The phase-contrast allows for higher feature contrast than conventional transmission tomography, as the phase interference gives rise to a sharp edge contrast. READ MORE

  3. 3. Harmonic Emissions in Microgrids

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Lejla Alibegovic; Emelie Freiland Paulsson; [2021]
    Keywords : Harmonics; microgrid; local energy system; NEPLAN; Technology and Engineering;

    Abstract : “Affordable and clean energy” is EUs 7th Sustainable Development Goal and includes an increase of renewable energy generation in the global energy mix. A lot of the responsibility falls on the energy sector to transform and obtain solutions for a more sustainable future. READ MORE

  4. 4. Development of an absorption model for gas discharge lamp simulation

    University essay from Malmö universitet/Malmö högskola/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Author : Oscar Vigstrand; [2021]
    Keywords : Discharge lamp; Plasma; UV radiation;

    Abstract : Ultraviolet (UV) light has been used for disinfection purposes for over 100 years. Irradiation by UV light is a method to disinfect surfaces in order to prevent microbiological growth. At Tetra Pak this is of great importance as they are manufacturer of filling machines. READ MORE

  5. 5. Bridging Sim-to-Real Gap in Offline Reinforcement Learning for Antenna Tilt Control in Cellular Networks

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

    Author : Mayank Gulati; [2021]
    Keywords : reinforcement learning; transfer learning; simulation-to-reality; simulator; realworld; real-world network data; remote electrical tilt optimization; cellular networks; antenna tilt; network optimization.;

    Abstract : Antenna tilt is the angle subtended by the radiation beam and horizontal plane. This angle plays a vital role in determining the coverage and the interference of the network with neighbouring cells and adjacent base stations. READ MORE
