  1. 1. Real-time Autofocus Algorithm in Laser Speckle Contrast Imaging

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Giovanni Russo; [2023]
    Nyckelord :Laser speckle contrast imaging; Autofocus; Blind image sharpness assessment; Speckle noise; Perimed’s Perfusion Speckle Imager;

    Sammanfattning : Microcirculation is defined as the blood flow in the smallest blood vessels. Laser speckle contrast imaging (LSCI) is a full field imaging technique that provides instantaneous 2-D perfusion maps of illuminated tissues based on speckle contrast. LÄS MER

  3. 2. Blind Acoustic Feedback Cancellation for an AUV

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Hampus Frick; [2023]
    Nyckelord :acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

    Sammanfattning : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. LÄS MER

  4. 3. Spatialisation of Binaural Audio With Head Tracking in First-Person Computer Games

    Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Patrik Bergsten; Mikita Kihan; [2023]
    Nyckelord :Sound localisation; head tracking; binaural; audio; computer games; experiences;

    Sammanfattning : Audio in today’s first person computer games plays a vital role in informing players about their surroundings as well as general gameplay elements. Awareness of the direction, distance, and spatial placement of audio sources can be crucial for players in various contexts. LÄS MER

  5. 4. Direct Signal Interference Suppression and Target Detection for Low-Cost SDR-Based Passive Bistatic Radar

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Oskar Jonsson; [2022]
    Nyckelord :passive radar; ECA; LMS; software-defined radio;

    Sammanfattning : Passive radar is a technology for detection of targets using echoes of existing radio transmitter, such as FM-radio. Since only receivers are needed for operation, a passive radar system has the possibility of being implemented using low-cost hardware. LÄS MER

  7. 5. RayTracing Analysis and Simulator Design of Unmanned Aerial Vehicle Communication and Detection System in Urban Environment

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

    Författare :Jie Huang; [2022]
    Nyckelord :Drone detection; phased array; angle of arrival; MUltiple SIgnal Classification; raytracing; reflection; diffraction; Drönardetektering; fasad array; ankomstvinkel; MUltiple SIgnal Classification; raytracing; reflektion; diffraktion;

    Sammanfattning : In recent years, unmanned aerial vehicles (UAV), also called drones, have experienced a rapid increase, which leads to the concern of illegal use of them. Passive RF is one of the effective ways to detect drones by receiving drones’ communication signals. LÄS MER
