  1. 1. Pixel correspondences for SLAM using sidescan sonar with canonical representations

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

    Author : Weiqi Xu; [2022]
    Keywords : ;

    Abstract : Acoustic instruments play an important role in autonomous underwater vehicles (AUVs). Sidescan sonar (SSS) detects a wider range, provides photo-realistic images in high resolution, and has lower price than the multibeam echo sounder (MBES). READ MORE

  3. 2. Echo of the Ancients: Evolution of Song in the Avian Family Cettiidae

    University essay from Uppsala universitet/Paleobiologi

    Author : Jared Goodstadt; [2022]
    Keywords : Cettiidae; song; acoustic analysis; PCA; Mahalanobis distance; phylogeny;

    Abstract : The Cettiidae, a family of primarily small, insectivorous, Asiatic and Austronesian, mountain birds have been the subject of acoustic analysis in the past. However, until this point, an in-depth review of the songs of the entire family had yet to be undertaken. READ MORE

  4. 3. Evaluation of OSTE-hybrid materials for acoustophoresis applications

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Elin Forss; [2020]
    Keywords : Acoustophoresis; off-stoichiometry-thiol-enes; OSTE; microfluidics;

    Abstract : This project aimed at exploring new hybrid materials to be used for acoustophoresis applications. Acoustophoresis can be used to manipulate particles inside a microfluidic channel by creating ultrasound standing waves within the channel [1]. This can be used for cell separation [2] or trapping of particles [3]. READ MORE

  5. 4. Acoustic echo cancellation inside a truck cabin

    University essay from Linköpings universitet/Statistik och maskininlärning

In earlier days only luxury cars had the feature of a hands free communication but now it has become one of the basic requirements in any segment of vehicles. READ MORE

  6. 5. Acoustic Characterization of the Cellulose-coated Perfluorocarbon Droplets based on Phase Velocity Measurements

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Emma Lindroth; [2020]
    Keywords : Ultrasound; Droplets; Contrast agent; Cellulose; Perfluorocarbon; Acoustic characterization; Non-destructive evaluation; Phase velocity; Bulk modulus; Compressibility;

    Abstract : Today, microbubbles are one of the most commonly used ultrasound contrast agents, since their high compressibility results in a strongly scattered signal. Despite this advantage, microbubbles experience limitations by the decreased stability and large diameter. READ MORE
