    Abstract : 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. READ MORE

  3. 22. 3D geospatial data requirements for simulating noise using the Nord2000 model: Case study of the impact of building façade types and roof configurations on simulated traffic noise levels

    Abstract : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. READ MORE

  4. 23. Harmonisk strömsimulering i inverterbaserade värmepumpar

    University essay from Umeå universitet/Institutionen för fysik

    Author : Alexander Magnusson; [2023]
    Keywords : Current harmonics; inverter-driven compressor; black box simulation;

    Abstract : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. READ MORE

  5. 24. Prediction of dementia based on older adults’ sleep disturbances using machine learning: a controlled experiment.

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Joel Nyholm; [2023]
    Keywords : Dementia; Sleep; Risk factors; Machine learning;

    Abstract : Background. Sleep disturbances can indicate an increased risk of dementia. This study examines whether machine learning can predict this association and which sleep disturbance factors impact dementia. Methods. READ MORE
