  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).

  3. 2. Polymer gel dosimetry with MRI-readout for 3D dose verification - detector characteristics and clinical applications

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Thi Guldhill; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. READ MORE

  4. 3. Development and understanding of a model V2O5/anatase TiO2(101) SCR catalyst

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

    Author : Johanna Paulsson; [2023]
    Keywords : Physics and Astronomy;

    Abstract : A model V2O5/ anatase TiO2(101) SCR catalyst is studied with the purpose of developing and understanding the reaction mechanism through which this catalyst reduces NOx. Several reaction mechanisms have been proposed for this catalyst in the past, but there is still no agreement on which of these describe the reaction the best, if any. READ MORE

  5. 4. Validation of simulation with enhanced kaon production to investigate kaon background for LDMX

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Lisa Andersson Loman; [2023]
    Keywords : Dark matter; experimental physics; simulations; kaons; particle physics; LDMX; background studies; mörk materia; partikelfysik; kaoner; Physics and Astronomy;

    Abstract : Dark matter is one of our universe’s largest mysteries and very little is known about what it is. One of the dominating theories, that it originates from an early universe thermal relic, indicates that it has interaction with the Standard Model. READ MORE

  6. 5. The effect of temperature on the chemical stability of Vitamin C in a cosmetic product – Development of an HPLC-method for quantitative analysis

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Sofia Thuresson; [2022]
    Keywords : Vitamin C; HPLC; Stability; Degradation; Antioxidant; Vitamin C; HPLC; Stabilitet; Nedbrytning; Antioxidant;

    Abstract : Vitamin C är en populär ingrediens i hudvårdsprodukter, bland annat på grund av dess positiva effekter på kollagen-produktionen i huden och dess antioxidativa egenskaper. Dessvärre är vitamin C en känslig ingrediens som lätt bryts ned av ljus, syre, hög temperatur eller fel pH-värde. READ MORE
