  1. 16. Speckles in Coherent LiDAR

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ivar Nyman; [2022]
    Nyckelord :Spckle; LiDAR; coherent;

    Sammanfattning : Speckles are a phenomenon which often appears in situations involving lasers. Their properties can be used as an advantage but in the case of LiDAR applications, they’re purelydestructive. The peaks and troughs of the intensity distribution across the collimatinglens can be seen as variations in signal strength at the detector. LÄS MER

  3. 17. Deformationsmätning av kubhörnsreflektorer med fotobaserad skanning och terrester laserskanning

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Mathias Erkkilä; Torkel Pettersson; [2022]
    Nyckelord :close-range photogrammetry; terrestrial laser scanning; deformation measurement; corner reflectors; InSAR; fotobaserad skanning; Terrester laserskanning; deformationsmätning; kubhörnsreflektor; InSAR;

    Sammanfattning : Kubhörnsreflektorer används som måltavlor med kontinuerlig och identifierbar reflekterad signalstyrka vid fjärranalys, bland annat för tekniken ”interferometric synthetic aperture radar” [InSAR]. Kubhörnsreflektorer tillämpas exempelvis för bevakning av sättningar i jordytan och kalibrering av [SAR]-system (”synthetic aperture radar”). LÄS MER

  4. 18. Investigation of Registration Methods for High Resolution SAR-EO Imagery

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Niclas Hansson; [2022]
    Nyckelord :SAR; FFT; MI; Image Registration;

    Sammanfattning : With advancements in space technology, remote sensing applications, and computer vision, significant improvements in the data describing our planet are seen today. Researchers want to gather different kinds of data and perform data fusion techniques between them to increase our understanding of the world. LÄS MER

  5. 19. TMS stimulus-response asymmetry in lower limbs : Difference in stimulated muscles between dominant and non-dominant leg

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Adna Pivac; [2022]
    Nyckelord :lower limbs; motor evoked potential; motor cortex; stimulus-response asymmetry; transcranial magnetic stimulation;

    Sammanfattning : Transcranial magnetic stimulation (TMS) is a 37-year-old non-invasive tool and can be used for diagnostic, therapeutics, and research purposes. In research, TMS is mostly used to stimulate the motor cortex, resulting in a neuroelectric excitatory response called a motor evoked potential (MEP). LÄS MER

  7. 20. DEFORMABLE IMAGE REGISTRATION OF SPINE MAGNETIC RESONANCE IMAGES WITH ELASTIX FOR DETAILED CHARACTERIZATION OF DISC LOADING BEHAVIORS

    Master-uppsats,

    Författare :Zainab Sirat; [2021-05-10]
    Nyckelord :Medical physics; Registration; MRI; Spine;

    Sammanfattning : Purpose: This work aimed to develop an optimized strategy for registration of spine magnetic resonance (MR) images acquired with and without spinal loading, as well as evaluate the quality of the registration strategy with commonly used quality assessment methods. Method: Previously collected MR images of the lumbar spine of 37 individuals were re analyzed. LÄS MER
