  1. 1. Malnutrition i Kapstaden : en kvalitativ studie om erfarenheter av att arbeta med malnutrition och dess bakomliggande orsaker

    Kandidat-uppsats, Sophiahemmet Högskola

    Författare :Fanny Arebark; Ellen Sandahl; [2024]
    Nyckelord :Cape Town; Malnutrition; Non-governmental organizations; Prevention; Strategies; Icke-statliga organisationer; Kapstaden; Malnutrition; Prevention; Strategier;

    Sammanfattning : Bakgrund Malnutrition är ett omfattande problem i Sydafrika och är orsaken bakom nästan hälften av dödsfall hos barn under 5 år i Sydafrika. Undernäring ger både kortsiktiga och långsiktiga konsekvenser på individ- och samhällsnivå. LÄS MER

  3. 2. Local voltage control in a low voltage grid with high photovoltaic penetration

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Joakim Bakklund; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. LÄS MER

  4. 3. Regularization Methods and High Dimensional Data: A Comparative Study Based on Frequentist and Bayesian Methods

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Markus Gerholm; Johan Sörstadius; [2024]
    Nyckelord :Linear regression; high dimensional data; regularization; Bayesian methods; Mathematics and Statistics;

    Sammanfattning : As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. LÄS MER

  5. 4. A Comparative Investigation of Classical Random and Quantum Walks in Terms of Algorithms, Implementation, and Characteristics

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Naoki Moriya; [2024]
    Nyckelord :Qunatum computing; quantum walk;

    Sammanfattning : In recent years, there has been a significant development in high performance computing, driven by advances in hardware and software technology. The performance of the computers to the present has improved in accordance with Moore’s law, on the other hand, it seems to be reaching the limits in the near future. LÄS MER

  7. 5. Risk-Averse Multi-Armed Bandit Problem with Multiple Plays

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Siri Dahlgren; Nicholas Marriott; [2023-10-23]
    Nyckelord :MAB; Gittins; Markovian bandit; risk-aversion; policy iteration; multiple plays;

    Sammanfattning : This study aims to construct an efficient heuristic, referred to as RA, for a riskaverse Markovian multi-armed bandit problem (MAB) with multiple plays. The RA incorporates risk-aversion and multiple plays by modifying the Gittins index strategy. LÄS MER
