  1. 1. Microfluidic flow splitter shape optimization for high throughput

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Christoffer Papamoustos Palmér; Joel Linder; [2023]
    Nyckelord :Genetic algorithms; Lab-on-a-chip; Optimization; Acoustofluidics; Microfluidics; Technology and Engineering;

    Sammanfattning : Due to an increasing incidence rate, the need for new effective methods for diagnosing cancer are of high importance. Studies have shown that circulating tumor cells, CTCs, have great potential as a diagnostic biomarker. Acoustophoresis is a label free method, capable of separating CTCs from red blood cells in a blood sample. LÄS MER

  3. 2. Finding the QRS Complex in a Sampled ECG Signal Using AI Methods

    Master-uppsats, KTH/Fysik

    Författare :Jeanette Marie Victoria Skeppland Hole; [2023]
    Nyckelord :ECG; ECG-analysis; QRS detector; Artificial Intelligence; Machine Learning; Deep neural networks; Long short-term memory; Convolutional neural network; Multilayer perceptron; EKG; EKG-analys; QRS detektor; Artificiell intelligens; Maskininlärning; Djupa neurala nätverk; Long short-term memory; Convolutional neural network; Multilayer perceptron;

    Sammanfattning : This study aimed to explore the application of artificial intelligence (AI) and machine learning (ML) techniques in implementing a QRS detector forambulatory electrocardiography (ECG) monitoring devices. Three ML models, namely long short-term memory (LSTM), convolutional neural network (CNN), and multilayer perceptron (MLP), were compared and evaluated using the MIT-BIH arrhythmia database (MITDB) and the MIT-BIH noise stress test database (NSTDB).

  4. 3. Development of Radon Detectors for Earthquake Prediction

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Alma Partos; Astrid Schöldström; [2023]
    Nyckelord :Radon; earthquake; gamma ray spectroscopy;

    Sammanfattning : The purpose of this project is to simulate the detection of γ-ray spectra emitted by radon isotopes and their daughters. This is done as a contribution to the development of radiation detectors to be used in a research project investigating the possibility of using increased amounts of the radioactive gas radon as an earthquake precursor.

  5. 4. Kompetens och fungerande samverkan skapar hållbarhet i mötet med perinatal psykisk ohälsa - en kvalitativ intervjustudie

    Magister-uppsats, Umeå universitet/Institutionen för omvårdnad

    Författare :Jessica Hellström-Kruséus; Lena Kaeiding; [2023]
    Nyckelord :Midwife; Experience; Thematic analysis; Mental illness; Maternal health care; Barnmorska; erfarenheter; Tematisk analys; Psykisk ohälsa; Barnmorskemottagning;

    Sammanfattning : Bakgrund: I Sverige förekommer perinatal psykisk ohälsa hos omkring 15 procent av alla gravida och rapporteras öka i samhället. Riskfaktorer för psykisk ohälsa anges vara sociala faktorer såsom våldsutsatthet, tidigare psykisk ohälsa, bristande socialt stöd eller familjehistorik av psykisk ohälsa. LÄS MER

  7. 5. Operando detection of Li-plating by online gas analysis and acoustic emission monitoring

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Inti Espinoza Ramos; [2023]
    Nyckelord :Li-ion batteries; graphite; solid electrolyte interphase; lithium plating; online gas analysis; operando acoustic emission monitoring;

    Sammanfattning : Lithium ion batteries (LIBs) are widely used for storing and converting chemical energy into electrical energy. During battery operation, lithium ions move between electrode materials, enabling energy storage. However, aging mechanisms like lithium plating can negatively impact battery performance and lifetime. LÄS MER
