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

    University essay from KTH/Fysik

    Author : Jeanette Marie Victoria Skeppland Hole; [2023]
    Keywords : 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;

    Abstract : 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).

    Keywords : EEG; Frequency Domain; Signal Analysis; Fast Fourier transform; EEG; Frekvensdomän; Signalanalys; Snabb Fourier transform.;

    Abstract : Many people experience discomfort during movement when using a knee prosthesis. As a result, a study is being conducted to see if biomedical models can be used to produce an optimal prosthetic socket to reduce discomfort. READ MORE

  4. 3. Dynamic analyses of hollow core slabs : Experimental and numerical analyses of an existing floor

    University essay from KTH/Bro- och stålbyggnad

    Author : Markus Hansell; Panagiotis Tamtakos; [2020]
    Keywords : Hollow core slab; Structural dynamics; Signal analysis; Mode shape; Frequency response function; Complex mode; FE-model; Håldäcksbjälklag; Strukturdynamik; Signalanalys; Modform; Frekvenssvar; Komplex mod; FE-modellering.;

    Abstract : For intermediate floors in residential and office buildings, as well as in parking garages and malls, there is a wide use of hollow core concrete slabs in Sweden today. Hollow core slabs are precast and prestressed concrete elements with cylindrical-shaped voids extending along the length of the slab. READ MORE

  5. 4. Kvalitativ och kvantitativ jämförelse mellan olika fonokardiografiska inspelningsverktyg för veterinärmedicinskt bruk

    University essay from SLU/Dept. of Clinical Sciences

    Author : Emil Nordh; [2017]
    Keywords : elektroniska stetoskop; fonokardiografi; hund; katt; jämförelse;

    Abstract : Auskultation av hjärtat med stetoskop är en viktig del i den kliniska diagnostiken och används dagligen av vårdpersonal världen över. Till skillnad från de analoga membranbaserade stetoskopen, erbjuder elektroniska stetoskop möjlighet till förstärkning och filtrering av ljud, simultan auskultation i grupp, lagring och återspelning av ljud, grafisk framställning av ljuden samt signalanalys.

  6. 5. Teaching Signals to Students: a Tool for Visualizing Signal, Filter and DSP Concepts

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Pouya Ashraf; Linnar Billman; Adam Wendelin; [2016]
    Keywords : signal processing; signal analysis; DSP; embedded systems; analog filters;

    Abstract : Students at Uppsala University have for some years been given the opportunity to take courses in subjects directly, or indirectly, related to the fields of signal processing and signal analysis. According to the directors of these courses, a considerable number of students are recurringly having difficulties grasping different concepts related to this field of study. READ MORE
