  1. 1. Oscillations in a complex sunspot: From theory to data

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

    Author : Femke Kranenbarg; [2024]
    Keywords : ;

    Abstract : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

  3. 2. Benchmarking a 1 kW hybrid hydrogen fuel cell system

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Jonathan Envall; [2023]
    Keywords : PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

    Abstract : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.

  4. 3. On quantum systems and the measurement problem

    University essay from Stockholms universitet/Fysikum

    Author : Nicolas Boulle; [2023]
    Keywords : Quantum physics; the measurement problem; quantum information; Hilbert spaces; physical systems; unitary; collapse; Euler angles parametrization; Copenhagen interpretation; many- world; measure;

    Abstract : We focus on the Tensor Product Structure (TPS) of the Hilbert space and the fact that a choice in the TPS has an impact on the representation of the studied quantum system. We define the measurement problem in quantum mechanics and present some theories about quantum mechanics, each of them highlighting a different approach to quantum measurements. READ MORE

  5. 4. Pathways towards universal access to electricity in West Africa : Case study of Mali and Senegal

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Vittorio Bozzo; [2023]
    Keywords : Universal electricity access; Senegal; Mali; OnSSET; GIS; PV mini-grid; Universell tillgång till el; Senegal; Mali; OnSSET; GIS; PV mininät;

    Abstract : Despite the vast solar potential in both Mali and Senegal, the electricity access in both countries remains one of the lowest in the world. The main problem is represented by the disparity between rural and urban settlements. In Senegal, the electricity access for rural areas was lower than 50%, while in Mali was around 35%. READ MORE
