  1. 1. Natural Language Inference Transfer Learning in a Multi-Task Contract Dataset : In the Case of ContractNLI: a Document Information Extraction System

    Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

    Författare :Yiu Kei Tang; [2023]
    Nyckelord :;

    Sammanfattning : This thesis investigates the enhancement of legal contract Natural Language Inference (NLI) classification through supervised fine-tuning on general domain NLI, in the case of ContractNLI and Span NLI BERT (Koreeda and Manning, 2021), a multi-task document information extraction dataset and framework. Annotated datasets of a specific professional domain are scarce due to the high time and labour cost required to create them. LÄS MER

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

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

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

    Sammanfattning : 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.

  4. 3. SURVEY OF SULPHATE-BEARING MINERALS IN LKAB'S TAILING POND

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :CELESTINE IFEANYI UGWUOKE; [2023]
    Nyckelord :Tailings; Sequential extraction; Mineralogy; Sulphate;

    Sammanfattning : This research project investigated the high concentration of sulphate in a tailing pond at LKAB and the characteristics and behavior of sulphate minerals in different areas of the pond. The sampling of the tailings was carried out at Nine stationary sampling points. LÄS MER

  5. 4. Critical elements scavenged by secondary gypsum and HFO : Determined by sequential extraction combined with mineralogical studies

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Emma Flodin; [2022]
    Nyckelord :Geochemistry; gypsum; HFO; adsorption; scavenged; critical elements; beryllium; Yxsjöberg; mine waste; Sequential extraction; XRD; SEM-EDS;

    Sammanfattning : The demand for metals is great for the purpose of developing green technologies, and EU has listed 30 metals and minerals that are of critical importance for the maintenance and evolving of today’s society, so called critical materials. However, mining of raw materials generates mine waste which can have adverse effect on human health, ecosystems, and surrounding areas. LÄS MER

  7. 5. P-cycling in sub-Arctic lakes – the importance of sediment release and retention

    Magister-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Hanna Ravry; [2022]
    Nyckelord :phosphorus; sediment; oligotrophication;

    Sammanfattning : Oligotrophication is generally caused by a decreased nutrient availability, usually due to phosphorous limitation. This is a phenomenon impacting the entire food web and at worst causing cascading alterations within an ecosystem. Lakes of the Northern Hemisphere have lately been documented to be subjected to oligotrophication (e.g. LÄS MER
