  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. Investigation of Injury Predictors for Rat Neuro Trauma

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Rosetta Maglio; [2024]
    Keywords : Finite element method; Rat brain traumatic brain injury; Rat brain finite element model; Strain; Strain rate; Product of strain and strain rate; Rotational direction; Rotational duration; Injury prediction; Finita elementmetoden; Råtthjärnans finita elementmodell; Belastning; Belastningshastighet; Produkten av belastning och belastningshastighet; Rotationsriktning; Rotationstid; Skadeförutsägelse;

    Abstract : A traumatic brain injury is usually caused by a direct impact to the head and is a common cause of disability and death all around the world. The most effective method to predict brain injury today, is to use a finite element head model. READ MORE

  4. 3. Adherence in patients with heart failure. Relationships to symptom burden and hospitalization frequency : A cross-sectional survey study

    University essay from Malmö universitet/Institutionen för vårdvetenskap (VV)

    Author : Helen Moe; [2024]
    Keywords : Adherence; Cross sectional study; Heart failure; Hospitalization-frequency; Non-adherence; Symptom burden;

    Abstract : Aim: The aim of the study was to investigate the degree of adherence and non-adherence to treatment regimen in the population with heart failure, as well as to explore relationships to symptom burden and hospitalization-frequency. Introduction: Heart failure – a chronic disease with a somber prognosis and high mortality, incidence and prevalence increasing world-wide. READ MORE

  5. 4. The association between obesity, low-grade inflammation, self-reported knee symptoms and radiographic knee osteoarthritis in individuals with knee pain : A longitudinal cohort study

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Alma Buer; [2024]
    Keywords : osteoarthritis knee pain; artros knä smärta;

    Abstract : Abstract  Background One of the earliest signs of knee osteoarthritis (OA) is knee pain which correlates with inflammation and disease severity. Knee OA affects 260 million worldwide, and is in similarity with obesity, characterized by ongoing low-grade inflammation. READ MORE

  6. 5. Exploring the Impact of Pseudo and Quasi Random Number Generators on Monte Carlo Integration of the Multivariate Normal Distribution

    University essay from Lunds universitet/Statistiska institutionen

    Author : Marcus Stolz; Jonathan Christopher; [2024]
    Keywords : Monte Carlo integration; Quasi monte carlo integration; Random number generation; Mathematics and Statistics;

    Abstract : This thesis examines the effects of pseudo and quasi-random number generators on the accuracy and efficiency of Monte Carlo Integration in the case of the multivariate normal distribution. The study compares the performance of the Mersenne Twister (a pseudo-random number generator) with Sobol and Halton sequences (quasi-random number generators). READ MORE
