    University essay from KTH/Tillämpad fysik

    Author : Joakim Anderberg; [2023]
    Keywords : General Defocus Particle Tracking; ultrasonic standing waves; microscopy; microchip; single plane particle tracking; levitation; Generel ur-fokus partikel spårning; stående ultraljudsvågor; mikroskopi; mikorchip; enkelplans partikel spårning; levitation;

    Abstract : Three-dimensional particle tracking is a valuable tool in microfluidics for obtaining information about a system. General Defocus Particle Tracking (GDPT) is a straightforward method of 3D particle tracking that only requires a single-camera plane, making it applicable to existing equipment in a laboratory.

  3. 2. Local Feature Correspondence on Side-Scan Sonar Seafloor Images

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Li Ling; [2021]
    Keywords : ;

    Abstract : In underwater environments, the perception and navigation systems are heavily dependent on the acoustic wave based sonar technology. Side-scan sonar (SSS) provides high-resolution, photo-realistic images of the seafloor at a relatively cheap price. READ MORE

  4. 3. Effect of sensory enrichments on the behaviour of captive Northern lynx (Lynx lynx lynx) and assessment of automated behaviour monitoring technologies

    University essay from Linköpings universitet/Biologi

    Author : Uranie JEAN-LOUIS; [2019]
    Keywords : Automatic monitoring; Environmental enrichment; Northern Lynx; Pacing; Odour; Sound;

    Abstract : Captive environments like zoo exhibits offer limited space, lacking many of the environmental stimuli that are present in the wild. This may reduce animal welfare and potentially lead to the development of stereotypic behaviour like pacing. Environmental enrichment is used to prevent and reduce pacing and enhance animal well-being. READ MORE

  5. 4. Defining habitat demands of Wels catfish (Silurus glanis) in a Swedish lake : a look into muddy waters

    University essay from SLU/Dept. Of Aquatic Resources

    Keywords : Wels catfish; Silurus glanis; Sweden; Spawning; Spawning habitats; acoustic camera; ARIS; telemetry;

    Abstract : The wels catfish (Silurus glanis) is a rare species in Swedish waters, it demands higher water temperatures than most lakes and rivers can offer. One of the few locations with naturally occurring wels catfish in Sweden is Lake Båven, situated about an hour and a half south of Stockholm, in the county of Södermanland. READ MORE

  6. 5. Sampling methods of the wels catfish (Silurus glanis) in freshwater lakes : management of a vulnerable species
