  1. 1. Analys och minskning av effektförlusterna i en borstlös likströmsmotor med vektorstyrning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Lider Xavier Garcia Parrales; [2023]
    Nyckelord :Effektförluster Borstlös likströmsmotor BLDC Vectorstyrning Field-oriented Control FOC Blockkommutering Block commutation MTPA; Technology and Engineering;

    Sammanfattning : This report addresses power losses in an electric motor arising from various sources. The choice of motor control strategy can decrease efficiency if not implemented correctly or if the motor model in the control loop is overly simplified. LÄS MER

  3. 2. Information Conveyance : An Examination of Using Level Design to Communicating the State of Play in a Competitive Video Game

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för teknik och estetik

    Författare :Ahab Ibrahim; Adam Xavier Andersson Novela; [2023]
    Nyckelord :Information conveyance; Level design; third-person shooter; Game design;

    Sammanfattning : This is a study on information conveyance, specifically a study on how specific level design techniques can be used to convey information to the players regarding a competitive multiplayer game's “state of play”. Through an analysis of different games, three different level design elements were identified as effective tools for conveying information and these elements are; architectural placement, visual cues and environmental changes.

  4. 3. Image and RADAR fusion for autonomous vehicles

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

    Författare :Xavier de Gibert Duart; [2023]
    Nyckelord :Image; Camera; Computer Vision; Data Fusion; Sensors; 3D data processing; Point Clouds; Calibration; MATLAB and RADAR; RADAR; kamera; datorseende; datafusion; sensorer; 3D-databehandling; punktmoln; kalibrering; MATLAB Image;

    Sammanfattning : Robust detection, localization, and tracking of objects are essential for autonomous driving. Computer vision has largely driven development based on camera sensors in recent years, but 3D localization from images is still challenging. Sensors such as LiDAR or RADAR are used to compute depth; each having its own advantages and drawbacks. LÄS MER

  7. 5. Deep learning for ultrasound image reconstruction on a realtime system

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Jason Wong; [2022]
    Nyckelord :;

    Sammanfattning : Ultrasound speed-of-sound reconstruction has been proven to provide images of higher quality in some specific clinical situations. However, commercial available ultrasound machines usually do not support speed-of-sound image reconstruction. LÄS MER
