  1. 1. Communication acoustics in classroom environments : on the use of assistive listening devices

    Författare :Johan Odelius; John S. Bradley; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : Assistive listening devices (ALDs) are used in classrooms to assist communication for students with hearing loss. An ALD, a system of external microphones, transmits sound directly to the students' hearing aids. The signal is coupled to the hearing aid using a radio frequency (FM) or an induction loop (IL) system. LÄS MER

  5. 4. Automated Squat Detection in Railway Switches & Crossings Using Vibration Measurements and Machine Learning

    Författare :Yang Zuo; Matti Rantatalo; Johan Odelius; Florian Thiery; Praneeth Chandran; Taoufik Najeh; João Carlos Elói De Jesus Pombo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Operation and Maintenance Engineering; Drift och underhållsteknik;

    Sammanfattning : Railway switches and crossings (S&Cs) play a vital role in the operational integrity of a railway network, and their malfunctioning poses substantial risks such as traffic disruptions, economic ramifications, and potential life-threatening accidents. Consequently, it becomes imperative to proactively identify potential defects in S&Cs at an early stage and maintain continuous monitoring of their condition to avoid adverse consequences. LÄS MER
