  1. 1. Impact of pre-treatments on the brightness stability of a conventional and near neutral pH ECF-light bleaching sequence

    University essay from KTH/Fiber- och polymerteknologi

    Author : Ali Amirjani; [2023]
    Keywords : ECF; Bleaching; Pulp; AOX; Brightness Stability; ECF; Blekning; Massa; AOX; Ljushetsstabilitet;

    Abstract : Syftet med denna studie är att undersöka inverkan av förbehandlingar på ljushetsstabiliteten av Northern Bleached Softwood Kraft (NBSK) som har blekts enligt (OO) (OP) D/Dn (PO) bleksekvensen. Effekten av förbehandling med xylanas (X), mild sur (A), DTPA (Q) samt ett kombinerad DTPA- & xylanassteg (Q+X) har studerats. READ MORE

  3. 2. Predicting tumour growth-driving interactions from transcriptomic data using machine learning

    University essay from Uppsala universitet/Neuroonkologi och neurodegeneration

    Author : Mathilda Stigenberg; [2023]
    Keywords : cancer; immunology; cell-cell interactions; deep learning; variational autoencoder; supervised variational autoencoder; tumour microenvironment; single-cell RNA sequencing; spatial transcriptomics; breast cancer; machine learning;

    Abstract : The mortality rate is high for cancer patients and treatments are only efficient in a fraction of patients. To be able to cure more patients, new treatments need to be invented. Immunotherapy activates the immune system to fight against cancer and one treatment targets immune checkpoints. READ MORE

  4. 3. Protein-based hydrogel electrolytes for stretchable Zn-ion batteries

    University essay from Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Author : Lovisa Byström; [2023]
    Keywords : Hydrogel; gelatin; kappa-carrangeenan; Zn-ion battery; Kemisk biologi; Kemisk biologi;

    Abstract : Stretchable aqueous-based Zn-ion batteries have shown promise as a sustainable and safe energy storage system for wearable electronics used in healthcare, sports, soft robotics, and prosthetics. A battery consists of the active electrode, electrolyte, current collector, and encapsulation. READ MORE

  5. 4. Machine Learning based Predictive Data Analytics for Embedded Test Systems

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Fayad Al Hanash; [2023]
    Keywords : Machine learning; Artificial Intelligence; Predictive data analytics; Embedded test systems; Confusion matrix; Predictive maintenance; Support vector machines; Random forest; Gradient Boosting; Multi-layer perceptron; Binary classification; Multi-class classification;

    Abstract : Organizations gather enormous amounts of data and analyze these data to extract insights that can be useful for them and help them to make better decisions. Predictive data analytics is a crucial subfield within data analytics that make accurate predictions. Predictive data analytics extracts insights from data by using machine learning algorithms.

  6. 5. Random curves and their scaling limits

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Jonatan Wächter; [2023]
    Keywords : Stochastic processes; Schramm-Loewner-Evolution; Random Walk; Brownian Motion; Harmonic Explorer;

    Abstract : We focus on planar Random Walks and some related stochastic processes. The discrete models are introduced and some of their core properties examined. We then turn to the question of continuous analogues, starting with the well-known convergence of the Random Walk to Brownian Motion. READ MORE
