  1. 1. Simulation of low frequency acoustic waves in small rooms : An SBP-SAT approach to solving the time dependent acoustic wave equation in three dimensions

    Kandidat-uppsats,

    Författare :Alva Fährlin; Olle Edgren Schüllerqvist; [2023]
    Nyckelord :room acoustics; numerical methods; SBP; SAT; acoustic wave equation.;

    Sammanfattning : Low frequency acoustic room behaviour can be approximated using numerical methods. Traditionally, music studio control rooms are built with complex geometries, making their eigenmodes difficult to predict mathematically. LÄS MER

  3. 2. Machine Learning-based MIMO Indoor Positioning

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Qiyi Chen; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. LÄS MER

  4. 3. Predicting eigenvalues and eigenmodes in non-rectangular rooms with machine learning techniques

    Master-uppsats, KTH/Teknisk akustik

    Författare :Oscar Lundin; [2022]
    Nyckelord :Machine learning; Finite elements; Plane wave decomposition; ResNet; Room acoustics; Tensorflow; Keras; Eigenfrequency prediction; Maskininlärning; Finita elementmetoden; Planvåguppdelning decomposition; Rumsakustik; ResNet; Tensorflow; Keras; Prediktering av egenvärden; Egenfrekvenser; Egenmoder.;

    Sammanfattning : Knowing the eigenfrequencies and eigenmodes is of great importance to interior design and a common acoustic engineering problem. Challenges in noise control makes knowing the lower eigenfrequencies particularly important. LÄS MER

  5. 4. Endogenic Production : subjective matter and bodily involvement

    Master-uppsats, Konstfack/Inredningsarkitektur & Möbeldesign

    Författare :Nils Ställborn; [2022]
    Nyckelord :Spatial design; interior architecture; interior design; textile furniture; textile structure; soft structure; squiggly structures; drafting; draw; drawstring; drawstring furniture; furniture; furniture design; textile architecture; Baroque; sewing furniture; form-production; endogenic; exogenic; endogenic approach; endogenic process; tectonic production; rectangular room; clothes; architecture; body; design method; wool; Texel wool; folds; pleats; material hierarchies; the senses; draping; shape; sustainable; norm criticism; exploring;

    Sammanfattning : The word endogenic means growing or proceeding from within, it is commonly used to describe the process of tectonic movement and earth crust formation caused by the extrusion of magmatic material. My project is a metaphorical exploration of the geological term “endogenic process” as well as an exploration of a design approach based on the term. LÄS MER

  7. 5. Konstruktion och vidareutveckling av SIRIUS skidbalk

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Joakim Schoultz; Tobias Wikberg; [2021]
    Nyckelord :;

    Sammanfattning : Denna kandidatrapport behandlar ett arbete resulterande i en ökning av hållfastheten hos en skidbalk ingående i bandvagnen BvS10. Projektet har utförts på uppdrag av BAE Systems Hägglunds under deras SIRIUS-samarbete med Luleå tekniska universitet. LÄS MER
