  1. 11. Improving proton therapy planning with photon-counting spectral computed tomography

    University essay from KTH/Fysik

    Author : Karin Larsson; [2023]
    Keywords : Proton therapy; Medical imaging; Computed Tomography; Protonterapi; Medicinsk avbildning; Datortomografi;

    Abstract : Proton radiation therapy is an alternative to conventional photon radiation therapy, which accounts for the majority of radiation treatments today. The rationale for using protons in radiation therapy lies in their dose deposition properties; photons deposit a radiation dose inversely proportional to the energy, and therefore tissue depth, while protons exhibit a sharp Bragg peak when traversing matter.

  3. 12. Cell Identification from Microscopy Images using Deep Learning on Automatically Labeled Data

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Fredrik Salomon-Sörensen; [2023]
    Keywords : Deep Learning; Cell Identification; Image Segmentation; Nuclei Segmentation; Convolutional Neural Networks; UNet; Image Analysis; Microscopy; Noisy Labels; Phase-Contrast; Automatic Labeling; Technology and Engineering;

    Abstract : In biology, cell counting provides a fundamental metric for live-cell experiments. Unfortunately, most researchers are constrained to using tedious and invasive methods for counting cells. Automatic identification of cells in microscopy images would therefore be a valuable tool for such researchers. READ MORE

  4. 13. Improving the user experience of touchscreen text-based code editor in an industrial robot controller

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

    Author : Xuanling Xu; [2023]
    Keywords : Industrial Robot Programming; Code Editor; Robot Controller; Teach Pendant; OmniCore FlexPendant; User Experience; Design Thinking; Industrirobotprogrammering; Kodeditor; Robotkontroller; Robotpendant; OmniCore FlexPendant; Användarupplevelse; Design Thinking;

    Abstract : This project investigated the touchscreen text-based code editor in OmniCore FlexPendant to improve its usability and user experience. This is a powerful but complex application used to program industrial robots. READ MORE

  5. 14. An operator theoretic approach to the Riemann Hypothesis

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Ramon Arjan van de Scheur; [2023]
    Keywords : Riemann hypothesis; Prime number theorem; Prime number theorem for arithmetic progressions; operator theoretic equivalent; compact operator; prime-counting function; Chebyshev function; Laplace transform; Fourier transform; convolution operator; weak topology; strong topology; compact perturbation; Tauberian theorem; Poisson kernel; holomorphic; self-adjoint; spectrum; trace; Mathematics and Statistics;

    Abstract : In 2023 an operator theoretic approach to the Prime Number Theorem was introduced by Olsen. In this thesis this approach is examined and applied to give a new, operator theoretic, proof of a different version of the Prime Number Theorem and of the Prime Number Theorem for arithmetic progressions.

  6. 15. Characterization of Carotid Atherosclerotic Stenosis on Photon-Counting Computed Tomography

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : My Celander; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction and aim Atherosclerotic stenosis located at the carotid bifurcation accounts for 10% − 20% of all Transient Ischemic Attacks (TIA) and ischemic strokes, which occurs when Atherosclerotic stenosis, or so-called plaque, ruptures. The current method to evaluate carotid atherosclerotic stenosis is to measure the degree of stenosis. READ MORE
