  1. 1. Embedded digital filter design and implementation

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Xiao Su; [2023]
    Nyckelord :;

    Sammanfattning : Digital filters have been widely used in signal processing, to reduce or remove unwanted signals of different types, such as noise, and interference, and to enhance or keep desired signals. They are implemented as algorithms on an embedded system (a microcontroller) or a computer.

  3. 2. Conductive interferences from multiple EC-motor installation : To measure and mitigate harmonics

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och system

    Författare :Victor Aitman; [2022]
    Nyckelord :harmonics; interharmonics; harmonic-mitigation; electromagnetic compability; EMC; övertoner; EC-motorer; störningar; övertonsreducering; elektromagnetiskt kompabilitet; EMC;

    Sammanfattning : Products produced by a Swedish company are requested to be investigated regarding their harmonic and inter-harmonic currents injected into the public supply system to comply with the Swedish standard SS-EN IEC 61000-3-2, Electromagnetic compatibility (EMC).    On behalf of Systemair Sweden AB, this bachelor thesis aims firstly to investigate if their product, PAFEC 4225 WH (Air Curtain), complies with standard SS-EN IEC 61000-3-2, and if not, what measures should be taken; and secondly to develop a low-cost instrument for the measurement of harmonics and inter-harmonics according to standard IEC 61000-4-7 related to the requirements on equipment used in standard SS-EN IEC 61000-3-2.

  4. 3. Two New Methods for Real-Time Per-Face Texture Mapping (Ptex)

    Kandidat-uppsats, KTH/Datavetenskap

    Författare :Hugo Dettner Källander; Julius Häger; [2022]
    Nyckelord :;

    Sammanfattning : Ptex (Per-Face Texture Mapping for Production Rendering) is a technology unveiled by Disney in 2008 that automatizes the process of applying textures to 3D models but is rarely used in real-time contexts, where this process is still largely manual and time consuming. This report aims to compare two new real-time methods, Reduced Traverse and Hybrid, to two existing ones, Discard and Traverse, which could give new insight into the feasibility of widespread real-time Ptex and consequent resource savings.

  5. 4. Evaluating the Impact of V-Ray Rendering Engine Settings on Perceived Visual Quality and Render Time : A Perceptual Study

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Andreas Linné; [2019]
    Nyckelord :V-Ray; Computer-Generated Imagery; Rendering; Perception; Subjective Evaluation;

    Sammanfattning : Background. In computer graphics, it can be a time-consuming process to render photorealistic images. This rendering process, called “physically based rendering” uses complex algorithms to calculate the behavior of light. LÄS MER
