  1. 16. Turning Night into Day : Does Skyglow affect Bat Activity and Timing of Emergence?

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Torge Gerwin; [2023]
    Keywords : Skyglow; Bats; Light pollution; Bat activity; Bat emergence; Riparian forest; Landscape composition; Multi-scale landscape; Landscape management; Sweden;

    Abstract : Artificial brightness of the night sky caused by the backscatter of artificial light in the atmosphere is a consequence of ongoing urbanization. Skyglow covers 88 % of Europe’s surface and poses significant threats to biodiversity. Extensive research on responses of bats to direct light pollution already revealed significant impacts.

  3. 17. Phase Unwrapping MRI Flow Measurements

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Mio Liljeblad; [2023]
    Keywords : phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

    Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

  4. 18. Enabling Wet strength agent-reductions through CMC-addition; A case study investigating the possibilities to lower PAE in packaging board with CMC.

    University essay from Karlstads universitet/Avdelningen för kemiteknik

    Author : Sara Christenson; [2023]
    Keywords : ;

    Abstract : In 2015, the United Nations adopted 17 different sustainability development goals. These goals were set for the global community to be guided by – but also to follow thus slowingdown climate change, prevent inequality, end poverty and make sure that by 2030 all people enjoy peace and prosperity.

  5. 19. Flood Simulation in the Colombian Andean Region Using UAV-based LiDAR : Minor Field Study in Colombia

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

    Author : Simon Höglund; Linus Rodin; [2023]
    Keywords : UAV; Unmanned aerial vehicle; LiDAR; Light detection and ranging; UAV-based LiDAR; UAV photogrammetry; Aerial photogrammetry; Flooding Colombia; UN Sustainability Development Goals; UAV; Obemannade flygfordon; LiDAR; Ljus- och avståndsdetektion; UAV-baserad LiDAR; UAV-fotogrammetri; Flygfotogrammetri; Översvämning Colombia; FN; hållbarhetsutvecklingsmål;

    Abstract : Flooding is a worldwide problem that every year causes substantial damage for the environment and stakeholders nearby, and this impact relates to several of the United Nations Sustainable Development Goals. Colombia is specially prone to flooding as 17% of its surface area is at risk of extreme flooding. READ MORE

  6. 20. Study of Triply Periodic Minimal Surfaces for Heat Transfer Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : María Xuan Celaya Granados; [2023]
    Keywords : ;

    Abstract : In the pursuit of enhancing heat exchanger efficiency, several heat transfer- enhancing strategies are employed. The traditional methods include surface vibrations, microchannels, and integration of vortex generators. Additionally, new solutions are being studied, taking advantage of other relevant improve- ments in the engineering field. READ MORE
