  1. 1. Positioning Electric Field Sensors in the Marine Environment Using Passage Data

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Maria Langkilde; [2021]
    Keywords : electromagnetism; electric field sensors; sensor; marine environment; elektromagnetism; elektriska fältsensorer; sensor; marin miljö;

    Abstract : When underwater sensors are being deployed there is always some uncertainty about the actual position of the sensors. The most common way of determine the sensors position is the use of hydro-acoustic methods. However, for electric field sensors the most favourable would be to use the sensor system itself.

    Abstract : Children in Swedish preschools are exposed to high noise levels that can cause hearing damage or voice related problems among both teachers and students, this since they have to raise their voice in order to make themselves heard in a noisy environment. Because of this it is of interest to be able to predict the sound environment in preschools. READ MORE

  3. 3. 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. 4. Evaluating Speech-to-Text Systems and AR-glasses : A study to develop a potential assistive device for people with hearing impairments
