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

    University essay from KTH/Maskinkonstruktion (Inst.)

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

    Abstract : 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. READ MORE

  6. 5. Indoor and Outdoor Measurements of Particulate Matter with the Low-Cost Optical Sensor OPC-N3

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Ellen Grace Soroka; [2020]
    Keywords : Physics and Astronomy;

    Abstract : This paper evaluates the low-cost optical sensor OPC-N3 from Alphasense as a suitable scientific instrument for measuring particulate matter levels in air, both outdoors and in- doors. The time-keeping and data-retrieval was additionally improved by connecting the OPC-N3 to an Arduino microcontroller equipped with a real-time clock (RTC) module and an external SD card. READ MORE
