  1. 1. Analysis of the Representation of Orbital Errors and Improvement of their Modelling

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Mini Gupta; [2018]
    Nyckelord :Space debris; space situational awareness; uncertainty characteristics; Gaussianity;

    Sammanfattning : In Space Situational Awareness (SSA), it is crucial to assess the uncertainty related to thestate vector of resident space objects (RSO). This uncertainty plays a fundamental role in, forexample, collision risk assessment and re-entry predictions. A realistic characterization of thisuncertainty is, therefore, necessary. LÄS MER

  3. 2. Tail Dependence Considerations for Cross-Asset Portfolios

    Master-uppsats, KTH/Matematisk statistik

    Författare :Johanna Trost; [2016]
    Nyckelord :;

    Sammanfattning : Extreme events, heaviness of log return distribution tails and bivariate asymptotic dependence are important aspects of cross-asset tail risk hedging and diversification. These are in this thesis investigated with the help of threshold copulas, scalar tail dependence measures and bivariate Value-at-Risk. LÄS MER

  4. 3. Parallel Hardware for Sampling Based Nonlinear Filters in FPGAs

    Master-uppsats, Linköpings universitet/Elektroniksystem; Linköpings universitet/Tekniska högskolan

    Författare :Rakesh Kota Rajasekhar; [2014]
    Nyckelord :Particle filters; Sampling Importance Resampling Filter; Hardware architectures; Bearings-only tracking.;

    Sammanfattning : Particle filters are a class of sequential Monte-Carlo methods which are used commonly when estimating various unknowns of the time-varying signals presented in real time, especially when dealing with nonlinearity and non-Gaussianity in BOT applications. This thesis work is designed to perform one such estimate involving tracking a person using the road information available from an IR surveillance video. LÄS MER
