  1. 1. Utmaningar i geometriundervisning: en djupdykning i innehåll, elevers missuppfattningar och lärarinterventioner

    Uppsats för yrkesexamina på grundnivå, Malmö universitet/Fakulteten för lärande och samhälle (LS)

    Författare :Linnea Listring; Ida Green; [2024]
    Nyckelord :geometric objects; two- and three dimensional objects; relational understanding; instrumental understanding; teaching methods; Van Hiele instructional model; practical elements; daily life;

    Sammanfattning : This text discusses final results from empirical studies, scientific articles and literature from the period 1990-2023, concerning teachers’ knowledge, students’ misconceptions and various teaching methods related to geometric objects. The results highlight challenges for both teachers and students in understanding and defining geometric shapes and figures. LÄS MER

  3. 2. Shape depiction using Local Light Alignment : Evaluating the shape enhancement capabilities of the Local Light Alignment technique at multiple scales

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Edvard Ahlsén; [2023]
    Nyckelord :Shape depiction; Non-photorealistic rendering; Shading; Multiple scales; Formskildring; ickerealistisk rendering; skuggning; skalrymdsmetoder;

    Sammanfattning : Local Light Alignment is a new shading based technique in the field of shape depiction, a field which concerns itself with techniques to represent and enhance the three-dimensional (3D) shape of objects in two-dimensional (2D) visual media. The main idea of Local Light Alignment is to locally adjust the incoming direction of light to create contrast in a way that enhances the perception of shape and surface detail. LÄS MER

  4. 3. Math Visualizations in VR

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Abraham Al-bashki; Ahmed Oogle; [2023]
    Nyckelord :;

    Sammanfattning : Visualization of linear algebra with virtual reality (VR) can be helpful for math teachers. A study has shown more engagement, focus, and active learning through immersion and interactivity, supplementing opportunities for visualizing abstract concepts. LÄS MER

  5. 4. Reduction of Noise and Artefacts in MRIScan of Metal Implant Reconstructed by Frequency Mapping

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Pontus Wahlqvist; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Metal objects can cause significant artefacts in magnetic resonance imaging (MRI) scans, cause loss of signal and what is known as geometric warping. There are ways to address these problems using different MRI sequences. This project looks at a newer method of artefact correction proposed by Månsson and Morin. LÄS MER

  7. 5. Automatic Shelf detection and Decluttering in Warehouseenvironments

    Uppsats för yrkesexamina på avancerad nivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Johan Larsson; [2022]
    Nyckelord :;

    Sammanfattning : The work in this report focuses on solving two problems that autonomous mobilerobots in a warehouse environment are facing; the removal of dynamic, includingsemi-static, objects (clutter) from the long-term map and how to locate shelves withinthe environment. Both done using a three-dimensional point cloud. LÄS MER
