  1. 1. Generation and Detection of Adversarial Attacks in the Power Grid

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Oscar Larsson; [2022]
    Nyckelord :Machine Learning; Adversarial Learning; Power Systems; State Estimation; Detectability Constraints;

    Sammanfattning : Machine learning models are vulnerable to adversarial attacks that add perturbations to the input data. Here we model and simulate power flow in a power grid test case and generate adversarial attacks for these measurements in three different ways. LÄS MER

  3. 2. RELIABILITY ANALYSIS OF REPAIRABLE SYSTEMS WITH COVARIATES: A CASE STUDY OF RAILWAY TRACK

    Master-uppsats, Luleå tekniska universitet/Drift, underhåll och akustik

    Författare :Alvaro Andres Rincon Franco; [2021]
    Nyckelord :Reliability; Railways; Covariates;

    Sammanfattning : Linear assets are complex industrial systems that extend from one geographical region to another. Given the criticality of the industrial activities linked to them, it is vital to accurately estimate the systems' reliability. LÄS MER

  4. 3. Residual-based test for Nonlinear Cointegration with application in PPPs

    Master-uppsats, Statistik

    Författare :Dao Li; [2008]
    Nyckelord :Nonlinear cointegration; Common features; Regime transition; Residual-based test; Purchasing power parities;

    Sammanfattning : Nested by linear cointegration first provided in Granger (1981), the definition of nonlinear cointegration is presented in this paper. Sequentially, a nonlinear cointegrated economic system is introduced. LÄS MER
