  1. 6. Space-Division-Multiplexing Platform for a Delayed-Choice Experiment

    University essay from Linköpings universitet/Informationskodning

    Author : Hilma Karlsson; [2023]
    Keywords : Wheeler s delayed choice; wave-particle delayed choice; Sagnac interferometer; Mach-Zehnder interferometer; complementarity relation; spatial modes; space-division-multiplexing; LP-modes; few-mode fibers; quantum communication; quantum optics;

    Abstract : This master’s thesis explores a space-division-multiplexing (SDM) platform fora delayed-choice experiment. SDM is a multiplexing technique for optical datatransmission that employs spatial modes in a multi- or few-mode fiber to increasethe transmission capacity. The spatial modes can thus be used as separate channels. READ MORE

  3. 7. Optimization of Radiotherapy Treatment Plans Based on Monte Carlo Dose Computations

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Ludvig Håkansson; [2023]
    Keywords : Technology and Engineering;

    Abstract : Treatment planning plays a vital role in providing good treatment to cancer patients. In order to reach an adequate treatment plan, the algorithm used for simulating the dose in the patient must model the reality well. READ MORE

  4. 8. Beyond Pulse Position Modulation : a Feasibility Study

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Danielle Gustafsson; [2023]
    Keywords : telecommunications; pulse position modulation; error-correction;

    Abstract : During the thesis work, a feasibility study of the BPPM error-correction protocol is performed. The beyond pulse position modulation (BPPM) protocol was invented at Ericsson AB and describes a modulation encoding using vertically and horizontally polarized single photons for optical transmission and error-correction.

  5. 9. Probing the Structure of Ionised ISM in Lyman-Continuum-Leaking Green Pea Galaxies with MUSE

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Chinmaya Nagar; [2023]
    Keywords : Emission-line ratio; Gaussian convolution; Green pea galaxies; ISM; Ionised ISM; Lyman continuum LyC ; Low-Redshift Lyman Continuum Survey LzLCS ; Lyman continuum emitter LCE ; LyC escape; LyC escape fraction; MUSE; MPDAF; Voronoi binning;

    Abstract : Lyman continuum (LyC) photons are known to be responsible for reionising the universe after the end of the Dark Ages, which marked a period called the Epoch of Reionisation (EoR). While these high-energy photons are thought to predominantly originate from young, hot, massive stars within the earliest galaxies, and contributions from high-energy sources like quasars and AGN, the origins of these photons are yet not well known and highly debated.

  6. 10. Polymer gel dosimetry with MRI-readout for 3D dose verification - detector characteristics and clinical applications

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Thi Guldhill; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. READ MORE
