  1. 1. Predicting and classifying atrial fibrillation from ECG recordings using machine learning

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Carl Bogstedt; [2023]
    Keywords : Bioinformatics; Machine Learning; Electrocardiogram; Classification; Rough Sets; XGBoost; Atrial Fibrillation;

    Abstract : Atrial fibrillation is one of the most common types of heart arrhythmias, which can cause irregular, weak and fast atrial contractions up to 600 beats per minute. Atrial fibrillation has increased prevalence with age and is associated with increased risks of ischemia, as blood clots can form due to the weak contractions. READ MORE

  3. 2. Dielectric Response and Partial Discharge Characteristics of Stator Winding Insulation System with SiC Stress Grading

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

    Author : Amar Abideen; [2020]
    Keywords : Stator Insulation; Dielectric Frequency Response; Polarization Depolarization Current; Insulation Modelling; FEM simulation;

    Abstract : The typical construction of a stator coil includes the use of end corona protection (ECP)coating, which is made of semi-conductive materials like silicon carbide (SiC). Thepurpose of ECP is to smooth the electric stress distribution near the slot exit, limitingthe electric field and partial discharge (PD) activity within the insulation system. READ MORE

  4. 3. Raman spectroscopy for characterization of soot and other carbonaceous materials

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

    Author : Jonatan Henriksson; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Raman spectroscopy is well known as a method that can be used to study the structural characteristics of carbon materials such as soot and carbon black. In this work, a Raman spectroscopy setup was used to record spectra of various carbonaceous samples under different experimental conditions. READ MORE

  5. 4. Investigation of magnetic order in nickel-5d transition metal systems

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Konstantinos Papadopoulos; [2019]
    Keywords : muSR; muons; skyrmions; magnetism; transition; spin; rotation; relaxation; resonance; thin; films; transition; metals; MBE; sputtering; XRR; reflectivity; molecular; beam; epitaxy; x; ray; TRIUMF; double; perovskite; longitudinal; transverse; nickel; Ni; asymmetry; positron; depolarization; chiral; lattice; helical; DM; interaction;

    Abstract : Double perovskite materials exhibit alterations in magnetic order through manipulation oftheir crystal structure. Certain ultra thin metallic bilayers can create an exotic magnetic stateof confined spin textures called skyrmions. In both cases, new atomic arrangements leadto new electrical and magnetic properties. READ MORE

  6. 5. Patologiska förändringar vid förmaksflimmer hos häst

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Nikita Durchbach; [2016]
    Keywords : förmaksflimmer; häst; patologi; prognos; atrial fibrillation; horse; pathology; prognosis;

    Abstract : Förmaksflimmer är den vanligaste arytmin hos häst. Syftet med uppsatsen är att redogöra för patologiska förändringar vid förmaksflimmer samt försöka klargöra vad som avgör prognos och recidivering vid behandling med kinidinsulfat och transvenös elkonvertering. READ MORE
