  1. 21. EVALUATION OF RADIATION DOSES USING CONE BEAM COMPUTED TOMOGRAPHY IN ENDOVASCULAR AORTIC REPAIR AND SCOLIOSIS PROCEDURES

    Master-uppsats,

    Författare :Louise Strandberg; [2021-04-06]
    Nyckelord :Medical physics; Cone beam CT; CT; EVAR; scoliosis; radiation dose; effective dose;

    Sammanfattning : Purpose: The study includes the two areas, vascular surgery and orthopedics, and focuses on endovascular aortic aneurysm repair (EVAR) and scoliosis procedures. EVAR procedures contribute to a high radiation dose to the patient and for scoliosis procedures, it is often young girls that are undergoing surgery. LÄS MER

  4. 23. Investigation of a New Method for Drone Dazzling Using Laser

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Jens Grundmark; [2021]
    Nyckelord :Drone countermeasure; Risley prisms; Camera dazzling; Laser;

    Sammanfattning : Drones have become more common, and are commercially available for consumers. Small drones can be used for unauthorized information gathering, or to cause disruptions. This has created a need for safe, effective countermeasures against drones. In this thesis, a method for countermeasures against drone imaging is investigated. LÄS MER

  5. 24. Characterization of as prepared and exposed Perovskitesolar cells by microscopic and spectroscopic techniques

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Nagaraju Gorella; [2021]
    Nyckelord :Perovskites; Solar Cell; SEM; AFM; c-AFM; Photoluminescence; Electroluminescence; Solar simulator.;

    Sammanfattning : Studying the microstructural features, optical, and electrical properties of the thin-filmperovskite solar cells (PSC) is the main objective of this thesis work. All the PSCs used in thisthesis work were prepared by spin coating assisted with gas quenching process and the samplesreceived from Interuniversity Microelectronics Centre (IMEC), Belgium. LÄS MER

  7. 25. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Jannek Hansen; [2021]
    Nyckelord :Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Sammanfattning : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. LÄS MER
