  1. 1. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Máté Károly Tóth; [2023]
    Keywords : Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

    Abstract : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

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

    University essay from Lunds universitet/Matematisk statistik

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

    Abstract : 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. READ MORE

  4. 3. The combination of SFDI with a mathematical model links perturbation in microcirculation to early stages of sepsis

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Caroline Korsfeldt; Sara Karajica; [2022]
    Keywords : SFDI; SFDS; mathematical modeling; sepsis;

    Abstract : The microcirculation system is crucial for the function of delivering biological markers such as oxygen and removing carbon dioxide from all the cells forming the complex ma- trix of tissue in the body. To keep up with the demands of each and every cell, there is a response from the microvasculature - resulting from for instance changes in blood flow to the tissue area. READ MORE

  5. 4. Development Of Lung Phantoms for Detection Of Acute Respiratory Distress Syndrome

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Wassim Wahbeh; Youssef Hasan; [2022]
    Keywords : DARDS;

    Abstract : The goal of this project was to fabricate a deflated and an inflated phantom to replicate how the human lung tissues’ permittivity changes under a pathological condition for instance acute respiratory distress syndrome (ARDS). Furthermore, the lung phantom should be shaped like real human lungs. READ MORE

  6. 5. Measuring Respiratory Frequency Using Optronics and Computer Vision

    University essay from Linköpings universitet/Datorseende

    Author : Per Antonsson; Jesper Johansson; [2021]
    Keywords : Computer Vision; Optical Flow; Motion Vectors; Respiratory Frequency; Signal Processing;

    Abstract : This thesis investigates the development and use of software to measure respiratory frequency on cows using optronics and computer vision. It examines mainly two different strategies of image and signal processing and their performances for different input qualities. READ MORE
