  1. 1. Feature Selection for Microarray Data via Stochastic Approximation

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Erik Rosvall; [2024-03-18]
    Keywords : feature selection; feature ranking; microarray data; stochastic approximation; Barzilai and Borwein method; Machine Learning; AI;

    Abstract : This thesis explores the challenge of feature selection (FS) in machine learning, which involves reducing the dimensionality of data. The selection of a relevant subset of features from a larger pool has demonstrated its effectiveness in enhancing the performance of various machine learning algorithms. READ MORE

  3. 2. Weather Factors and E. coli Concentration in Barnviken, Malmö - A Linear Mixed Model Approach

    University essay from Lunds universitet/Statistiska institutionen

    Author : Elias Gullberg; [2024]
    Keywords : Linear Mixed Models; Mathematics and Statistics;

    Abstract : Barnviken in Malmö has persistently encountered challenges associated with elevated concentrations of Escherichia coli (E. coli) without a discernible source of contamination. READ MORE

  4. 3. Simulation-based discrimination of Crab pulsar models with XL-Calibur

    University essay from KTH/Fysik

    Author : Dennis Åkerström; [2024]
    Keywords : Astroparticle Physics; Astrophysics; Detector Physics; Simulation; Theoretical Physics; Engineering Physics; Pulsar models; Crab pulsar; Astropartikelfysik; Astropartikelfysik; Detektorfysik; Simulering; Teoretisk Fysik; Teknisk Fysik; Pulsar modeller; Krabbpulsaren;

    Abstract : Polarisation of X-ray light is being investigated with polarimeters to extend the borders of what can be observed. Distant compact objects, such as pulsars, that are to small on the sky to be analysed with imaging can be investigated by analysing the polarisation of the emitted light. This can reveal physics previously hidden by their small nature. READ MORE

  5. 4. Assessing water balance and yields in Malawian cropping systems : maize soybean and maize Gliricidia systems resilience against climate change

    University essay from SLU/Dept. of Soil and Environment

    Author : Danila Valeriano; [2024]
    Keywords : crop modelling; APSIM; Malawi; maize; soybean; Gliricidia; agroforestry; legume intercropping; climate predictions; climate adaptation; SDSM;

    Abstract : In Malawi, maize monocultures are increasingly susceptible to extreme weather patterns, causing considerable yield reduction and heightened food insecurity for smallholder farmers dependent on rainfed subsistence agriculture. Diversifying cropping systems is crucial for ensuring yield resilience. READ MORE

  6. 5. Hormonal Influence on the Proliferation Potential of C17.2 Neuronal Progenitor Cells

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Alexander Mangano; [2024]
    Keywords : ;

    Abstract : The brain is arguably the most complex organ of the body: Controlling muscles, maintaining homeostasis, processing information. It has the longest developmental period of any organ, and hormones are essential during its development. READ MORE
