1. 21. Optimal control of articulated vehicles for tyre wear minimisation

   University essay from KTH/Fordonsdynamik

   Author : Vallan Maroof; [2021]
   Keywords : Articulated Vehicles; Optimal Control; Tyre Wear Minimisation; Sensitivity Analysis; Motion Planning; Lastbil; Ruttplanering; Däckslitage Minimering; Känslighetsanalys; Optimal Styrning;

   Abstract : Tyre wear is a significant problem on today's road vehicles, particularly for heavy trucks. As the tyre wears, microplastics is released in the air causing long term health issues and environmental pollution. With the introduction of automated vehicles there is a big potential to improve tyre wear of heavy trucks. READ MORE

3. 22. F-theory on six-dimensional symmetric toroidal orbifolds

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Finn Bjarne Kohl; [2021]
   Keywords : F-theory; orbifolds; String Theory; String Phenomenology; roto-translations; six-dimensional; F-Theorie; Orbifaltigkeiten; String Theorie; String Phenomenologie; Roto-Translationen; sechs-dimensional;

   Abstract : In this thesis, compactifications of F-theory on six dimensional symmetric toroidalorbifolds are explored. These orbifold geometries have been mathematically classified and it is natural to ask what the physical implications of string theorycompactifications on those geometries are. READ MORE

4. 23. Markov Chain Monte Carlo (MCMC) and Bayesian Inference for Gravitational Waves

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Christine Andersson; [2021]
   Keywords : Gravitational Waves; LISA; LISA mission; Bayesian Inference; Markov Chain Monte Carlo; MCMC; Bayes’ Theorem; stochastic sampling; Metropolis Hastings; histograms; Physics and Astronomy;

   Abstract : The Laser Interferometer Space Antenna (LISA) is a space borne gravitational wave detec- tor set to launch in 2034, with the objective of detecting and studying the Gravitational Waves (GWs) of our universe. So far, ground-based detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO) have been successful in detecting GWs, but the limitations of ground based detectors is what makes LISA so special.

5. 24. Multiple fly-by for interplanetary missions

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Javier Chivite Sierra; [2021]
   Keywords : ;

   Abstract : Current state-of-the-art of propulsion system for space vehicles does not allow to deliver therequired payload for the mission to all bodies in the Solar System. Therefore, alternatives havebeen developed to reach those bodies without having the necessary technology. READ MORE

6. 25. Surf Simulation with the Shallow Water Equations : Coupling of a surfer model to a shallow water wave

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Anton Thorell; [2021]
   Keywords : ;

   Abstract : This thesis covers the subject of deriving and solving the system of partial differential equations known as the Shallow Water Equations (SWE), and coupling the solutions of this equation system to a simplified model of a surfer - or any floating object, with the right choice of parameters. The SWE are generally used to analyze fluid movement on shallow areas, such as ocean waves nearing the shore, and are derived from the Navier-Stokes equations and restricted to conservation of mass and momentum in a fluid.
