  1. 11. Optimal Multitaper Spectrograms

    University essay from Lunds universitet/Matematisk statistik

    Author : Markus Ydreskog; [2023]
    Keywords : Time-frequency analysis; Multitaper spectrogram; Optimization; Wigner distribution; Mathematics and Statistics;

    Abstract : Multitaper spectrograms have been proposed as a method of improving the spectrogram as a time-frequency representation (TFR). This thesis aimed to investigate both previously used and new methods for combining multitaper spectrograms of a Gaussian signal and a chirp. READ MORE

  3. 12. Multi-Agent Information Gathering Using Stackelberg Games

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yiming Hu; [2023]
    Keywords : Information gathering; Autonomous exploration; Multi-agent coordination; Multi-agent system; Informationsinsamling; Autonom utforskning; Samordning av flera agenter; multiagentsystem;

    Abstract : Multi-agent information gathering (MA-IG) enables autonomous robots to cooperatively collect information in an unfamiliar area. In some scenarios, the focus is on gathering the true mapping of a physical quantity such as temperature or magnetic field. READ MORE

  4. 13. Procedural Worlds : A proposition for a tool to assist in creation of landscapes byprocedural means in Unreal Engine 5

    University essay from Linköpings universitet/Informationskodning

    Author : Viktor Sjögren; William Malteskog; [2023]
    Keywords : Procedural Generation; PCG; Terrain generation; Unreal Engine; Path generation; Catmull-Rom splines; Noise; Perlin noise; Biomes; Interpolation;

    Abstract : This thesis explores the possibilities of creating landscapes through procedural means within the game engine Unreal Engine 5. The aim is to provide a flexible procedural landscape tool that doesn't limit the user and that is compatible with existing systems in the engine. READ MORE

  5. 14. Modeling and quantifying uncertainty in bus arrival timeprediction

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Olof Josefsson; [2023]
    Keywords : uncertainty quantification; arrival time prediction;

    Abstract : Public transportation operates in an environment which, due to its nature of numerous possibly influencing factors, is highly stochastic. This makes predictions of arrival times difficult, yet it’s important to be accurate in order to adhere to travelers expectations. READ MORE

  6. 15. Parameter Stability in Additive Normal Tempered Stable Processes for Equity Derivatives

    University essay from Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Author : Eduardo Alberto Alcantara Martinez; [2023]
    Keywords : Parameter Stability; Lévy Processes; Calibration; Volatility Surface; Subordination; Additive Normal Tempered Stable Processes; Stable Distribution; Variance Gamma Process; Normal Inverse Gaussian Process.;

    Abstract : This thesis focuses on the parameter stability of additive normal tempered stable processes when calibrating a volatility surface. The studied processes arise as a generalization of Lévy normal tempered stable processes, and their main characteristic are their time-dependent parameters. READ MORE
