  1. 6. Tracking Optimization in Agrivoltaic Systems : A Comparative Study for Apple Orchards

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

    Author : Maddalena Bruno; [2023]
    Keywords : Agrivoltaics; Optimization; Light sharing; Apple Orchards; Lantbruk; Optimering; Ljusdelning; Äppelodlingar;

    Abstract : Agrivoltaic (APV) systems, based on the co-location of solar panels and crops, are an innovative solution to land-use conflicts that often arise between agriculture and energy production. Their optimal functioning starts with efficient management and sharing of light between solar panels and underlying plants. READ MORE

  3. 7. Space Weather Simulation Model Integration

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Alice Molin; Julia Johnstone; [2023]
    Keywords : simulation model; OpenSpace; GAMERA; HDF5; NASA; space weather; magnetosphere; field lines; cut plane; curvilinear grids; data extraction; integration; visualization; hierarchical data format; textures; transfer function; Medicinsk teknik; Medicinsk teknik;

    Abstract : Space weather is the field within the space sciences that studies how the Earths magnetosphere is influenced by the Sun. The Sun is constantly emitting dangerous radiation and plasma which in some cases can affect or damage the systems on Earth. READ MORE

  4. 8. Design of a Dielectric Radome using a Ray-Tracing Model for Satellite Communications

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

    Author : Flores Espinosa Núria; [2023]
    Keywords : Dielectric radome; Ray tracing; Array antenna; Lens antenna; Satellite communications; Radom dielèctric; Traçat de Rajos; Arranjament d’antenes; Antena de lent; Comunicacions per satèl·lit; Dielektrisk radome; Strålspårning; Gruppantenn; Linsantenn; Satellitkommunikation;

    Abstract : In recent years, there has been a huge increase in the use of satellite communications. This has led to a need for more capacity, which can be solved by moving towards higher frequency bands in search of higher bandwidths. READ MORE

  5. 9. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Måns Boll; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.

  6. 10. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

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

    Author : Lassi Linnala; [2022]
    Keywords : femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

    Abstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.
