  1. 1. Audibility & Preference of DA Overload Associated with True Peak : Investigation of claims made against overload prevention

    Kandidat-uppsats, Luleå tekniska universitet/Musik, medier och teater

    Författare :Mattias Strand; [2023]
    Nyckelord :true peak; mastering; inter-sample; intersample; peaks; peaking; overload; digital to analog; da; loudness; clipping; truncation; square wave;

    Sammanfattning : The conversion of audio from the digital to analog domain has the potential to result in distortion due to converter overload. This occurs because some peaks in the signal cannot be defined digitally and only become problematic during the conversion into the analog domain, exceeding the level that can be represented by the converter, causing it to overload.

  3. 2. Model Development for Wave Energy Converter Arrays in the Frequency Domain

    Master-uppsats, Uppsala universitet/Elektricitetslära; Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Linn Fredriksson; [2023]
    Nyckelord :Physics; Energy Physics; Energy; Renewable Energy; Wave Power; CorPower Ocean; Point Absorber; Array Modelling; Farm modelling; Fysik; Energifysik; Energi; Vågkraft; Förnyelsebar Energi;

    Sammanfattning : In this thesis, a model has been developed to analyze the behavior of wave energy converter arrays in the frequency domain. This development serves the purpose of establishing an in-house model tool for array modelling for CorPower Ocean. LÄS MER

  4. 3. Acoustic Characterization of Catalyst

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Surachit Dokson; [2023]
    Nyckelord :;

    Sammanfattning : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. LÄS MER

  5. 4. Harmonic Filters For Electronic Drive Systems Targeting Aircraft Applications

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Emelie Berglund; [2023]
    Nyckelord :Active Cancellation Filter; BLDC;

    Sammanfattning : Climate change pressures fossil-driven vehicles into electrification to sustain a healthy planet and environment for its inhabitants. Air traffic contributes to the ongoing climate crisis, and electric aircraft is taking its toll on the avionics market. LÄS MER

  7. 5. A Novel Two-Level Inverter Design for Efficient Energy Conversion in a Maglev Train Rail

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Oskar Zetterström; Stefan West Westholm; [2023]
    Nyckelord :IGBT; Inverter; Gate-driver; Prototype; Pulse width modulation; Sine wave; Maglev train; IGBT; Växelriktare; Grinddrivenhet; Prototyp; Pulsbreddsmodulering; Sinusvåg; Maglevtåg;

    Sammanfattning : This report covers the construction of a prototype inverter system designed to power the rail of a maglev train, from component selection through simulations and power demands to mounting and wiring the components into a cabinet. The inverter is made with insulated gate bipolar transistors controlled with pulse-width modulated signals provided by a custom microcontroller. LÄS MER
