  1. 1. Decoding communication of non-human species - Unsupervised machine learning to infer syntactical and temporal patterns in fruit-bats vocalizations.

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Luigi Assom; [2023]
    Keywords : animal decision making; unsupervised machine learning; UMAP; autoencoders; classifiers; bioacoustics; combinatory syntax; animal communication;

    Abstract : Decoding non-human species communication offers a unique chance to explore alternative intelligence forms using machine learning. This master thesis focuses on discreteness and grammar, two of five linguistic areas machine learning can support, and tackles inferring syntax and temporal structures from bioacoustics data annotated with animal behavior.

  3. 2. Automatic Annotation of Speech: Exploring Boundaries within Forced Alignment for Swedish and Norwegian

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Klaudia Biczysko; [2022]
    Keywords : forced alignment; automatic speech recognition; ASR; natural language processing; under-resourced languages; Swedish; Norwegian; CTC segmentation; wav2vec2; kaldi; HTK; dynamic time warping;

    Abstract : In Automatic Speech Recognition, there is an extensive need for time-aligned data. Manual speech segmentation has been shown to be more laborious than manual transcription, especially when dealing with tens of hours of speech. READ MORE

  4. 3. Acoustic properties of a 5G Telecom Equipment Shroud Design for Noise suppression

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : David Andersson; [2021]
    Keywords : Acoustics; 5G; Shroud; Telecom; Noise reduction; Akustik; 5G; Kåpa; Teleutrustning; Ljudisolering;

    Abstract : As technology moves forward it has a tendency to consume more and more power that needs to be cooled by bigger and louder fans, this is especially true for the new generation of 5G radio equipment. This Master thesis is a collaboration with Ericsson and attempts to construct a shroud for containing a number of 5G radio units whilst attenuating the fan noise of the units as effectively as possible.

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

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Henriikka Taipale; [2021]
    Keywords : 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;

    Abstract : 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.
