  1. 1. Developments Towards High-Resolution Muonic Atom X-ray Spectroscopy of Low-Z Elements : For precision measurements of absolute nuclear charge radii

    University essay from Uppsala universitet/Högenergifysik

    Author : Benjamin Verbeek; [2023]
    Keywords : muon physics; subatomic physics; charge radius; nucleus; lithium; silicon drift detector; microcalorimeter;

    Abstract : This Master's thesis investigates a method to measure atomic nuclei with record precision using muonic atom X-ray spectroscopy. In particular, 6Li is measured experimentally. The method used is independent from the previous most precise measurement of the 6Li nuclear charge radius which uses electron scattering. READ MORE

  3. 2. Silicon Drift Detector Simulations for Energy-Dispersive X-ray Spectroscopy in Scanning Electron Microscopy

    University essay from Stockholms universitet/Fysikum

    Author : Sebbe Blokhuizen; [2023]
    Keywords : X-ray spectroscopy; Silicon drift detector; Scanning Electron Microscopy; Detector Simulation;

    Abstract : Scanning Electron Microscopy combined with Energy Dispersive X-ray Spectroscopy (SEM-EDS) is a widely applied elemental microanalysis method. The integration of silicon drift detectors (SDDs) has notably enhanced EDS performance, enabling precise elemental identification due to its large sensitive area and low output capacitance.

  4. 3. Pruning a Single-Shot Detector for Faster Inference : A Comparison of Two Pruning Approaches

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

    Author : Karl Beckman; [2022]
    Keywords : Computer Vision; Object Detection; Single-Shot Detector; SSD-MobileNetV2; Iterative Pruning; Datorseende; Objektdetektering; Enstegsdetektor; SDD-MobileNet-V2; Iterativ Beskärning;

    Abstract : Modern state-of-the-art object detection models are based on convolutional neural networks and can be divided into single-shot detectors and two-stage detectors. Two-stage detectors exhibit impressive detection performance but their complex pipelines make them slow. READ MORE

  5. 4. Principles and Values from Cooperatives on Gotland: Fostering Sustainable Destination Development through Alternative Economies and Regenerative Practices

    University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Author : Valentina Rodoni; [2022]
    Keywords : alternative economies; cooperatives; values and principles; regenerative development; regenerative tourism; degrowth; sustainable destination development;

    Abstract : This research investigates the values and principles of cooperatives in relation to regenerative development and evaluates how these principles can be applied to foster SDD on Gotland. As alternative economies, cooperatives represent an opportunity to facilitate a regenerative type of development that is needed to face the issues brought by the capitalist system and the tourism industry.

  6. 5. Design of flow guiding parts through CFD topology optimisation

    University essay from KTH/Fordonsdynamik

    Author : Aby Narayamparambil; [2021]
    Keywords : Topology optimisation in CFD; Ansys Fluent; Tosca Fluid; Particle track; Backflow tolerance; Topologi optimering i CFD; Ansys Fluent; Tosca Fluid; Particle track; Återflödets tolerans;

    Abstract : Scania works continuously to develop internal combustion engines and after treatment systems which can achieve low pollutant emissions and high efficiency. A major principal that Scania adopted for this goal is the Simulation Driven Development (SDD) process. READ MORE
