  1. 11. Deep morphological quantification and clustering of brain cancer cells using phase-contrast imaging

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Jonas Engberg; [2021]
    Keywords : Glioblastoma; UMAP; Heterogeneity; Clustering; Convolutional neural network; Siamese neural network;

    Abstract : Glioblastoma Multiforme (GBM) is a very aggressive brain tumour. Previous studies have suggested that the morphological distribution of single GBM cells may hold information about the severity. This study aims to find if there is a potential for automated morphological qualification and clustering of GBM cells and what it shows. READ MORE

  3. 12. Effect of Ion Channels on Intracellular Localization of REV-ERBα in Glioma-Initiating Cells

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Selay Oba; [2021]
    Keywords : cancer; childhood cancer; glioblastoma multiforme; GBM; SR9009; mibefradil; REV-ERBα;

    Abstract : The number of children and young adolescents diagnosed with cancer is increasing, leading to a need for new therapeutic strategies with diminished neurodegenerative side- effects. This report presents preliminary observations on glioma-initiating cells (GICs) in the way to develop a strategy that induces cell-cycle arrest or quiescence in neural stem cells (NSCs). READ MORE

  4. 13. Differences in tumor volume for treated glioblastoma patients examined with 18F-fluorothymidine PET and contrast-enhanced MRI

    University essay from Umeå universitet/Institutionen för fysik

    Author : Karolina Hedman; [2020]
    Keywords : PET MRI; positron emission tomography; magnetic resonance imaging; brain tumor; glioblastoma; image segmentation; adaptive thresholding; feature extraction; radiotracer; gadolinium; image processing; image analysis;

    Abstract : Background: Glioblastoma (GBM) is the most common and malignant primary brain tumor. It is a rapidly progressing tumor that infiltrates the adjacent healthy brain tissue and is difficult to treat. Despite modern treatment including surgical resection followed by radiochemotherapy and adjuvant chemotherapy, the outcome remains poor. READ MORE

  5. 14. Predicting Risk of Delays in Postal Deliveries with Neural Networks and Gradient Boosting Machines

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Matilda Söderholm; [2020]
    Keywords : Machine Learning; Artificial Neural Networks; Gradient Boosting; Delivery prediction; Delay prediction; Postal Deliveries;

    Abstract : This thesis conducts a study on a data set from the Swedish and Danish postal service Postnord, comparing an artificial neural network (ANN) and a gradient boosting machine (GBM) for predicting delays in package deliveries. The models are evaluated based on F1-score for the important class which represents the data points that are delayed and needed to be identified. READ MORE

  6. 15. Machine Learning and Telematics for Risk Assessment in Auto Insurance

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

    Author : Frithiof Ekström; Anton Chen; [2020]
    Keywords : Telematics for car insurance; Gradient Boosting Machine; Neural Network; Machine Learning;

    Abstract : Pricing models for car insurance traditionally use variables related to the policyholder and the insured vehicle (e.g. car brand and driver age) to determine the premium. READ MORE
