1. 21. Numerical Solvers of the p-Stokes Equations with Applications in Ice-Sheet Dynamics

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Sebastian Myrbäck; Jonatan Risberg; [2020]
   Keywords : ;

   Abstract : In glacier dynamics – i.e. the field of research concerning the movement of ice – intricate mathematical models are used to describe its motion. Ice can be considered as a highly viscous, non-Newtonian fluid, obeying a set of equations closely related to the well-known Navier-Stokes equations describing classical fluid mechanics. READ MORE

3. 22. Development and Assessment of Re-Fleet Assignment Model under Environmental Considerations

   University essay from KTH/Optimeringslära och systemteori

   Author : Prashant Prashant; [2020]
   Keywords : Aviation; Fleet Assignment; Greenhouse Gases; Linear Optimization; Resource Management; Applied Mathematics; Mathematical Modelling; Flygindustrin; Tillämpad Matematik; Linjär Optimering; Fleet Assignment; matematisk modellering;

   Abstract : The imminent threat of global catastrophe due to climate change gets more real by each passing year. The Aviation trade association, IATA, claims that Aviation accounts for approximately 2% of the Greenhouse Gases (GHG) caused by human activities, and 3.5% of the total Radiative Forcing. READ MORE

4. 23. Evaluating the Practicality of Using a Kronecker-Factored Approximate Curvature Matrix in Newton's Method for Optimization in Neural Networks

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Magnus Tornstad; [2020]
   Keywords : ;

   Abstract : For a long time, second-order optimization methods have been regarded as computationally inefficient and intractable for solving the optimization problem associated with deep learning. However, proposed in recent research is an adaptation of Newton's method for optimization in which the Hessian is approximated by a Kronecker-factored approximate curvature matrix, known as KFAC.

5. 24. Multilateration in Direct ShortRange Communications Networks : Utilising Basic Safety Messages and Received Signal Strength Ranging

   University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Author : Andrew Galbraith; [2020]
   Keywords : DSRC; trilateration; multilateration; RSS; V2X;

   Abstract : Traditional satellite positioning systems have limited resolution and have proved inaccuratein areas such as urban canyons where signals are subject to bounce phenomena or indeed may be entirely unavailable. An alternative method of positioning is that of tri/multilateration, which uses known positions and distances from beacon points to locate a receiver. READ MORE

6. 25. Original: X-ray Spectral Analysis of a Serendipitously Observed Active Galactic Nucleus

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Teodor Elmfeldt; Filip af Malmborg; [2020]
   Keywords : ;

   Abstract : An active galactic nucleus (AGN) is a region in the center of a galaxy with a supermassive black hole continuosly accreting material. This accretion gives rise to large amounts of radiation across the whole electromagnetic spectrum, and largely affects the regions around the AGN and the evolution of the whole galaxy. READ MORE
