  1. 1. Speech Classification using Acoustic embedding and Large Language Models Applied on Alzheimer’s Disease Prediction Task

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

    Author : Maryam Kheirkhahzadeh; [2023]
    Keywords : Speech classification; Alzheimer’s disease detection; GPT-3; BERT; Text embedding; Dementia; wav2vec2.0; Klassificering av tal; detektion av Alzheimer’s sjukdom; GPT-3; BERT; textinbäddning; demens; wav2vec2.0;

    Abstract : Alzheimer’s sjukdom är en neurodegenerativ sjukdom som leder till demens. Den kan börja tyst i de tidiga stadierna och fortsätta under åren till en allvarlig och obotlig fas. Språkstörningar uppstår ofta som ett av de tidiga symptomen och kan till slut leda till fullständig mutism i de avancerade stadierna av sjukdomen. READ MORE

  3. 2. Analogue Circuit for Detection of Ageing Phenomena in Electric Drives

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

    Author : Yudong Lin; [2023]
    Keywords : Electric Drives; Ageing Process; Pulse-Width Modulation; Ringing Current; Peak Holder; Analogue Circuits; Elektriska drivsystem; Åldringsprocess; Pulsbreddsmodulering; Ringningar i strömmen; Toppvärdesdetektor; Analog krets;

    Abstract : This master thesis presents an analogue peak holder circuit design aimed at facilitating the non-invasive inspection of the ageing process in electric drives. The ageing process of electric drives is a crucial aspect that demands accurate monitoring to ensure their long-term performance and reliability. READ MORE

  4. 3. Unsupervised Detection of Interictal Epileptiform Discharges in Routine Scalp EEG : Machine Learning Assisted Epilepsy Diagnosis

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Shuai Shao; [2023]
    Keywords : EEG; electroencephalography; IED; interictal epileptiform discharges; spike detection; epilepsy; unsupervised; Fourier transform; STFT; short-time Fourier transform; CWT; continuous wavelet transform; DWT; discrete wavelet transform; ML; machine learning; ANN; artificial neural network; CNN; convolutional neural network; autoencoder; HMM; hidden Markov model; ECS; Euclidean distance of cumulative spectrum;

    Abstract : Epilepsy affects more than 50 million people and is one of the most prevalent neurological disorders and has a high impact on the quality of life of those suffering from it. However, 70% of epilepsy patients can live seizure free with proper diagnosis and treatment. Patients are evaluated using scalp EEG recordings which is cheap and non-invasive. READ MORE

  5. 4. Detection and quantification of post-translational modifications in non-invasive samples : Phosphoproteins as biomarkers and a market analysis of protein quantification technologies

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Sammi Baudin; Hillevi Fjellström; Aron Kraft; Erica Lamberg; Måns Rosenbaum; Hanna Sjöstrand; [2023]
    Keywords : Phorphorylation; Proteomics; Biomarkers; Phosphoproteins; PTM; Amyotrophic lateral sclerosis; ALS; Alzheimer s disease; Parkinson s disease; Cancer; xMAP; SIMOA; NULISA; PEA; ELISA; Mass spectrometry; SomaScan;

    Abstract : Post-translational modifications (PTMs) of proteins can be a sign and/or cause of disease. These modified proteins have the potential to be used as biomarkers for diagnostic purposes. However, research in the field is limited. READ MORE

  6. 5. Comparative Analysis of Transformer and CNN Based Models for 2D Brain Tumor Segmentation

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Henrik Träff; [2023]
