  1. 16. Probability Based Path Planning of Unmanned Ground Vehicles for Autonomous Surveillance : Through World Decomposition and Modelling of Target Distribution

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Per Liljeström; [2022]
    Nyckelord :Probability based path planning; Unmanned ground vehicles; UGV; Autonomous surveillance; Cell decomposition; Spatial partitioning; Target distribution modeling; Decay function; Last-seen function; Stochastic processes; Markov chain; Markov process; Markov planner;

    Sammanfattning : The interest in autonomous surveillance has increased due to advances in autonomous systems and sensor theory. This thesis is a preliminary study of the cooperation between UGVs and stationary sensors when monitoring a dedicated area. The primary focus is the path planning of a UGV for different initial intrusion alarms. Cell decomposition, i. LÄS MER

  3. 17. HR options and their valuation – a case study

    Master-uppsats, KTH/Fastighetsekonomi och finans

    Författare :Stefanos Nalmpantis; [2022]
    Nyckelord :Human Resources Options; Human Capital; Real Option Valuation; Personaloptioner; Humankapital; Real Optionsvärdering;

    Sammanfattning : This thesis introduces and discusses the notion that real options theory can be applied to investment decisions when the value lies in human capital. This approach contributes in circumventing traditional problems which arise during valuation of intangible assets. LÄS MER

  4. 18. Financial Modelling Using Fractional Processes And The Wiener Chaos Expansion

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Olof Hummelgren; [2022]
    Nyckelord :fractional Brownian motion; fBM; applied mathematics; Wiener chaos expansion; Wick product; Hurst parameter; fraktionell Brownsk rörelse; tillämpad matematik; Wiener kaosexpansion; Wickprodukt; Hurstparameter;

    Sammanfattning : The aim of this thesis is to simulate stochastic models that are driven by a fractional Brownian motion process and to apply these methods to financial applications related to yield rate and asset price modelling. Several rough volatility processes are used to model the asset price and yield dynamics. LÄS MER

  5. 19. Copula Modelling of High-Dimensional Longitudinal Binary Response Data

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Nils Henningsson; [2022]
    Nyckelord :Copula; latent model; variational inference; Copula; latent modell; variational inference;

    Sammanfattning : This thesis treats the modelling of a high-dimensional data set of longitudinal binary responses. The data consists of default indicators from different nations around the world as well as some explanatory variables such as exposure to underlying assets. LÄS MER

  7. 20. Performance of Stochastic Volatility and GARCH Models in Different Market Regimes

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Felix Viitanen; Erik Lundgren; [2022]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Reliable methods for estimating financial return volatility are crucial in many areas of trading and investing. Two such frameworks, the GARCH and SV, have been of particular interest to academics and practitioners alike. The GARCH model describes the variance of the current innovation as a function of the actual sizes of the previous innovations. LÄS MER
