  1. 1. Self-reported voice symptoms and voice handicap during virtual teaching compared to face-to-face teaching : A survey-based study on Swedish teachers in high schools and institutions of higher education

    Magister-uppsats, Uppsala universitet/Blom Johansson: Logopedi

    Författare :Maria Allebeck; Olivia Åberg; [2022]
    Nyckelord :Voice disorders; Work environment; School teachers; Distance learning; COVID-19; Röststörningar; Arbetsmiljö; Skollärare; Distansutbildning; Covid-19;

    Sammanfattning : Purpose: Since the beginning of 2020, teachers all over the world have had to switch over to virtual teaching because of the COVID-19 pandemic. This change of teaching mode has unknown consequences on the vocal health of teachers. LÄS MER

  3. 2. Pixel correspondences for SLAM using sidescan sonar with canonical representations

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

    Författare :Weiqi Xu; [2022]
    Nyckelord :;

    Sammanfattning : 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). LÄS MER

  4. 3. Design of Autonomous Underwater Vehicle’s (AUV) Antenna System

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

    Författare :Chengzhuang Zhou; [2021]
    Nyckelord :AUV Antenna; Printed Dipole Antenna; Broadband Antenna; AUV antenna; Printed dipole antenna; Broadband antenna;

    Sammanfattning : The ocean symbolizes mystery, passion, and power. However, most of the ocean, about 80 %, is unknown to humans. AUVs (Autonomous Underwater Vehicles) provide a platform where terrain mapping, the biodiversity, and the resource survey of the ocean become accessible. LÄS MER

  5. 4. Assessing indoor environmental quality and occupant comfort in modern wood buildings with post-occupancy evaluation and building performance simulation

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Henriikka Taipale; [2021]
    Nyckelord :Climate change; Post-occupancy evaluation; Building performance simulation; Residential; Wood buildings; Engineered wood products; Indoor environmental quality; Thermal comfort; Indoor air quality; Acoustics; Visual comfort; Case study; Denmark; Technology and Engineering;

    Sammanfattning : The European building sector is a source of significant negative environmental impacts, and large part of its carbon emissions can be attributed to heating, cooling and lighting of buildings – in other words, regulating buildings’ indoor environments. As people spend most of their lives indoors, there is a great challenge to create comfortable indoor environments, while also striving for further energy-efficiency and lower environmental impact.

  7. 5. An indicative case-control study of noise perception due to environmental noise sources

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Marcus Johansson ; [2020]
    Nyckelord :Noise perception; Psychoacoustics; Environmental noise; Bullerpåverkan; Psykoakustik; Samhällsbuller;

    Sammanfattning : The subject of the thesis was proposed by the acoustic consultancy firm Brekke & Strand, which is of relevance for their additional understanding and development of services and contribution to robust solutions. The aim with this thesis is to give indicative results and to dig deeper into the relation between environmental noise and the perception of the same, specially focusing on construction related noise but also permanent noise sources that originates from infrastructure.
