  1. 1. 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

  3. 2. Mechatronic Bedbug Attractor : Attracting bedbugs using the principles of human breathing

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

    Författare :Simon Lilja; Maja Åstrand; [2022]
    Nyckelord :Mechatronics; Simulated breathing; Bedbugs; Carbon dioxide; Solenoid valve.; Mekatronik; Simulerad andning; Vägglöss; Koldioxid; Magnetventil;

    Sammanfattning : Bedbugs are insects which exclusively feed on the blood of humans and other large animals. Bedbug infestations are a growing problem in modern society and some of the current solutions involve humans acting as bait to lure the bedbugs out of their nests. LÄS MER

  4. 3. Dynamic Modelling of the Patient Circuit for High Frequency Ventilation

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Samuel Eriksson; [2022]
    Nyckelord :Mechanical ventilation; high frequency ventilation; patient circuit dynamics; parameter estimation; system identification; Mekanisk ventilation; högfrekvent ventilation; patientkretsens dynamik; parameterestimering; systemidentifiering;

    Sammanfattning : Artificial breathing is vital when it comes to treatment of critically ill patients where the natural breathing mechanism is insufficient. With the help of mechanical ventilators, the natural breathing mechanism of the patient can be assisted or even exchanged with the artificial breathing from the machine. LÄS MER

  5. 4. Breathing Effects in Proton Scanning for Hodgkin's Lymphoma

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :John Nilsson; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose/Background Proton beam scanning (PBS) for mediastinal Hodgkin's Lymphoma (HL) is limited when treating in free-breathing (FB) due to breathing motion in the thoracic region. Tumour motion and the time structure of the beam delivery will cause interplay and dose blurring effects, resulting in discrepancies of dose in the planned dose distribution both inside and at the edges of tumour volume (TV).

  7. 5. Micro-Shivering Detection : Detection of human micro-shivering using a 77 GHz radar

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Elyas Razzaghi; Arno Van Hoek; [2019]
    Nyckelord :micro-shivering; vibration; vital signs; mmwave radar; fmcw radar; chirp signal; snr; phase accuracy;

    Sammanfattning : Radars have been under steady development to track, identify, image, and classify targets. Modern radar systems, with the help of embedded systems, have additional comprehensive signal processing capabilities. They can extract useful information from very noisy data, e.g. LÄS MER
