  1. 21. Insights into the burning behaviour of wood in the cone calorimeter

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ellinor Sanned; [2022]
    Keywords : Wood combustion; fire test; cone calorimetry; heat release rate; char formation;

    Abstract : Climate change and its accompanying environmental issues have caused the building industry to use more environmentally friendly building materials. Wood have always been a buildingmaterial but due to the renewed interest in imparting sustainability and renewability, its usage has increased over the recent years. READ MORE

  3. 22. Polymer gel dosimetry - Using MRI-readout, simplified relatively non-toxic mixing procedure tested on FLASH

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Maria Blomstedt; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Background: One of the polymer gel dosimeters available today is the N-isopropylamide (NIPAM) polymer gel dosimeter which has a less toxic monomer compared to other polymer gels and the advantage of being able to be manufactured under normal oxygen levels. Polymer gel dosimeters in general are advantageous independent dosimeters to use for verification of new radiation treatment techniques due to its favorable qualities such as very high resolution, 3D coverage, tissue equivalence and independence of energy and incident direction of the radiation beam.

  4. 23. Evaluating Sentinel-2 based phenology and productivity data for crop monitoring in Swedish agricultural fields

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Daniel Erlström; [2022]
    Keywords : Geography; Phenology; Agriculture; Yield; Remote Sensing; Sentinel-2; Productivity; Earth and Environmental Sciences;

    Abstract : Sentinel-2 based data provides interesting opportunities for land monitoring and applications in agriculture. High-Resolution Vegetation Phenology and Productivity (HR-VPP) is derived from Sentinel-2 data and offers up to 13 metrics. READ MORE

  5. 24. Design and evaluation of ambient RF energy harvesting platform for sensor-based systems : An experimental study of RF energy harvesting

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

    Author : Ibrahim Hamed; [2022]
    Keywords : Radiofrekvensenergiskördning; Trådlös energiskördning; Backscattering-teknik; Programvarudefinierad radio; EMC; PCB; Antenn;

    Abstract : Trådlös energiskörd möjliggör förmågan att skörda energi från elektromagnetisk strålning. Med de senaste framstegen inom trådlös kommunikationsteknik och med tillgången till energieffektiva sensorer, så har radiofrekvensenergiskördning potential till att bli en självförsörjande sensorbaserad plattform.
