  1. 1. 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

  3. 2. Parameters

    Master-uppsats, Lunds universitet/Industridesign

    Författare :Linus Brorsson; [2023]
    Nyckelord :Arts and Architecture; Technology and Engineering;

    Sammanfattning : Abstract This project delves into the interplay of physical interfaces of electronic devices and the creative act of making music. Through a literature review, it was understood that there are key UI & UX principles which need to be followed in the development of user-friendly products of this type. LÄS MER

  4. 3. Design, Modeling, and Testing of a Force Feedback Haptic Device for Simulated Robot Interaction

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Patrik Lindström; [2023]
    Nyckelord :Force Feedback; Impedance Control; PD-gain; Dynamic Behavior; Closed-chain; Master-Slave; Parallel Manipulator; Kinematics Redundancy; Mass-Spring-Damper; Position Control; Current Control; Modeling; Design; Joints; Delta robot; Differential Equations; External Torques; Kinematics; Forward Kinematics; Inverse Kinematics; Dynamic Matrices; Jacobian; URDF; Haptics; Haptic Device; Solidworks; CAD; Maxon Motors; EtherCAT; Beckhoff;

    Sammanfattning : Haptic feedback is a growing phenomenon that incorporates the sense of touch through tactile sensations such as vibrations, electrical signals, air pressure, and sound waves or through force feedback, which employs torques and/or forces to replicate the pressure and weight of a simulated object. Utilizing haptic technology establishes a communication bridge between the user and the technical component, enhancing the user's understanding of the technical component's surroundings. LÄS MER

  5. 4. Generating Perturbative Solutions for Slowly Rotating Perfect Fluids Using the Hartle Scheme

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Elin Johansson; [2023]
    Nyckelord :;

    Sammanfattning : In this thesis, we study slowly rotating relativistic stars by modeling them as perfect fluids. The Hartle formalism is used to perturb a spherically symmetric static solution into slow rotation and the corresponding field equations to second order are presented. LÄS MER

  7. 5. Feasibility of quantitative 99mTc-DPD scintigraphy SPECT/CT for assessing the burden of ATTR cardiac amyloidosis

    Master-uppsats, Umeå universitet/Radiofysik

    Författare :Sajad Kadhim Khalaf; [2023]
    Nyckelord :QSPECT; Amyloidosis; ATTR; LVMI; Recovery Coefficient; SUV; Calibration;

    Sammanfattning : Background: Amyloid transthyretin (ATTR) cardiomyopathy is caused by the deposition of misfolded proteins, known as amyloid fibrils, in the myocardium. Quantitative Single Photon Emission Computed Tomography (QSPECT) utilizing 99mTc-DPD scintigraphy has the potential to assess ATTR-suspected cardiac amyloidosis (CA). LÄS MER
