    Sammanfattning : Epilepsy affects more than 50 million people and is one of the most prevalent neurological disorders and has a high impact on the quality of life of those suffering from it. However, 70% of epilepsy patients can live seizure free with proper diagnosis and treatment. Patients are evaluated using scalp EEG recordings which is cheap and non-invasive. LÄS MER

  3. 2. Cost Efficient Scrap Metal Sourcing

    Master-uppsats, Lunds universitet/Teknisk logistik

    Författare :Sophia Sandström; Sofia Ivarsson; [2022]

    Sammanfattning : The steel industry in Sweden is responsible for 10% of the annual Swedish CO2 emissions. As a way to abate this sector, H2 Green Steel are establishing a new green steel production site in Boden. Their way of producing steel, through the EAF route and by using hydrogen-reduced DRI will reduce the CO2 emissions by over 90%. LÄS MER

  4. 3. Automatisk metod för läs-screening i lågstadiet

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ada Lindmark; Christian Vos; [2020]
    Nyckelord :läs-screening; läsutvecklingsschema; LUS; forced alignment; dynamic time warping; DWT.;

    Sammanfattning : En av de mest centrala delarna av undervisningen i lågstadiet fokuserar på svenskämnet och speciellt elevers läsförmåga. Trots obligatoriska screeningmoment och nationella bedömningsstöd uppfattar personal inom skola att kartläggning av läskunskaper är tidskrävande, komplext och subjektivt till följd av dess manuella format.

  5. 4. Lossless Image compression using MATLAB : Comparative Study

    Kandidat-uppsats, Blekinge Tekniska Högskola

    Författare :Surya Teja Kodukulla; [2020]
    Nyckelord :Algorithms; Compression Ratio; Efficiency; Image Compression; Lossless; Lossy; Quality;

    Sammanfattning : Context: Image compression is one of the key and important applicationsin commercial, research, defence and medical fields. The largerimage files cannot be processed or stored quickly and efficiently. Hencecompressing images while maintaining the maximum quality possibleis very important for real-world applications.
