1. 21. Path Choice Estimation in Urban Rails : Asimulation based optimisation for frequency-based assignment model

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Alexander Adolfsson; [2022]
   Nyckelord :Black-Box Optimisation; Optimization; Simulation based optimisation; Transit Network; Automaton; Urban Transport; Public transportation; Black-Box optimering; Optimering; Simuleringsbaserad Optimering; Transportsystem; Automation; Local Transport; Kollektivtrafik;

   Sammanfattning : Transit system have a large importance in modern urban cities, with urban rail often acting as the central system with it efficient travel time and great capacity. As cities grow in population, so to does the usage of urban rail resulting in increased crowding on the platform and in the trains. LÄS MER

3. 22. Models for solid waste and its management in Stockholm metropolitan area

   Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Lars Arvidsson; Kasper Nordenram; [2022]
   Nyckelord :;

   Sammanfattning : In the transition from a linear economy to a sustainable circular economy, waste management is critical. This thesis approaches the management of Municipal Solid Waste (MSW) from the perspective of a mathematical modelling. Within the scope of the thesis, three mathematical models were developed.

4. 23. Extended Kalman Filter as Observer for a Hydrofoiling Watercraft : Modelling of a new hydrofoiling concept, based on the Spherical Inverted Pendulum Model

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Adam Thålin; [2022]
   Nyckelord :Extended Kalman Filter; Hydrofoiling; Spherical Inverted Pendulum; Sensor Fusion; Simulink; Bärplan; Extended Kalman Filter; Farkostteknik; Inverterad Pendel; Sensorfusion; Sex frihetsgrader; Simulink;

   Sammanfattning : Hydrofoiling in general has the potential to revolutionize watercraft in the future since it allows smoother and faster transport on water with less energy consumption than traditional planning hulls. Even if the concept of hydrofoiling has been around since the last century, development in control theory and material science together with increased computing power has led to a growing interest for the technology.

5. 24. Bermudan Option Pricing using Almost-Exact Scheme under Heston-type Models

   Master-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

   Författare :Mara Kalicanin Dimitrov; [2022]
   Nyckelord :Almost Exact Scheme; Monte Carlo; Bermudan Options; Least Squares Monte Carlo; CIR; Heston Model; Double Heston Model; Stochastic Volatility;

   Sammanfattning : Black and Scholes have proposed a model for pricing European options where the underlying asset follows a so-called geometric Brownian motion which assumes constant volatility. The proposed Black-Scholes model has an exact solution. LÄS MER

7. 25. Adaptive detection of anomalies in fuel system of Saab 39 Gripen using machine learning : Investigating methods to improve anomaly detection of selected signals in the fuel system of Gripen E.

   Master-uppsats, Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

   Författare :Ahlgren Bergström Olof; [2022]
   Nyckelord :Machine Learning; Adaptive anomaly detection; Modeling; Fuel system; Saab Gripen;

   Sammanfattning : The process of flying fighter jets naturally comes with tough environments and manoeu-vres where temperatures, pressures and forces all have a large impact on the aircraft. Part degeneration and general wear and tear greatly affects functionalities of the aircraft, and it is of importance to carefully monitor the well being of an aircraft in order to avoid catastrophic accidents.
