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

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Joel Nyholm; [2023]
    Nyckelord :Dementia; Sleep; Risk factors; Machine learning;

    Sammanfattning : 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. LÄS MER

  3. 22. Estimation of respiratory frequency from Heart Rate Variability

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Daniel Ågärd; [2023]
    Nyckelord :time-frequency analysis; multitaper spectrogram; Optimization; signal processing; heart rate variability; Mathematics and Statistics;

    Sammanfattning : In this master's thesis the ability to estimate the respiratory frequency from heart rate variability measurement is analyzed. The goal was to implement a solution that is easily transferable to real time. LÄS MER

  4. 23. Frequency Stabilization in low Inertia Systems With Battery Power Injections

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

    Författare :Leif Lundin; [2023]
    Nyckelord :;

    Sammanfattning : The challenges for the power system of the future becomes increasingly larger when large amountsof renewable energy sources are integrated, and when conventional forms of power such asnuclear power are phased out. This results in a greater difficulty in quickly deploying FrequencyContainment Reserves in the event of of power balance disturbance, to stabilize frequency andvoltage. LÄS MER

  5. 24. Introducing disturbances to a chopped PIR sensor when investigating the performance in an office environment

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Maria Sandahl; Joel Fröberg; [2023]
    Nyckelord :;

    Sammanfattning : This master's thesis, conducted in collaboration with Knowit Connectivity, aims to develop a booking device for meeting rooms. The focus of the project is to identify and mitigate disturbances in the C-PIR sensor introduced by Haili Liu et al. LÄS MER

  7. 25. Vårdmiljöns pårverkan på patienters återhämtning : En allmän litteraturöversikt utifrån ett patientperspektiv

    Kandidat-uppsats, Mälardalens universitet/Akademin för hälsa, vård och välfärd

    Författare :Majken Hoffmann; Ronya Henze; [2023]
    Nyckelord :Allmän litteraturöversikt; patientperspektiv; vårdmiljö; återhämtning;

    Sammanfattning : Background: Previous research highlights the perspectives and experiences of nurses and relatives on the importance of the health facility environment for patient recovery. Nurses perceive noise as a disturbance to patients' rest, which can negatively impact their recovery. LÄS MER
