1. 1. Symmetry in a free boundary problem

   University essay from KTH/Matematik (Avd.)

   Author : Seuri Basilio Kuosmanen; [2023]
   Keywords : Analysis of PDEs; Bernoulli-type boundary condition; free boundary problem; Laplacian operator; method of moving planes; symmetry; Analys av PDEs; Bernoulli-typ randvärde; frirandsproblem; Laplaceoperatorn; moving-plane metoden; symmetri;

   Abstract : We consider a variational formulation of a Bernoulli-type free boundary problem for the Laplacian operator with discontinuous boundary data. We show the existence of a weak solution to the problem. Moreover, we show that the solution has symmetry properties inherited by symmetric data. READ MORE

3. 2. Dynamic Modeling of Heat Power System : Modeling of a Heat Power System Using Physical and Data-driven Methods and Investigation of a Moving Boundary Method

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

   Author : Albin Gustafsson; [2023]
   Keywords : System identification; Dynamic modeling; Organic Rankine cycle; Moving boundary; Thermodynamics.; System identifikation; Dynamisk modellering; Organisk Rankinecykel; Rörliga randvillkor; Termodynamik.;

   Abstract : Our society is becoming more and more electrified every day. However, a significant portion of the world’s electricity generation relies on the combustion of fossil fuels to produce heat, which is subsequently harnessed to generate electricity. One way of generating electricity from heat is by utilizing a Rankine cycle. READ MORE

4. 3. Moving in the dark : Mathematics of complex pedestrian flows

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Meghashyam Veluvali; [2023]
   Keywords : Mathematical modelling of pedestrian dynamics; stochastic systems; evacuation time; random walk method; parabolic equation; finite difference method;

   Abstract : The field of mathematical modelling for pedestrian dynamics has attracted significant scientific attention, with various models proposed from perspectives such as kinetic theory, statistical mechanics, game theory and partial differential equations. Often such investigations are seen as being a part of a new branch of study in the domain of applied physics, called sociophysics. READ MORE

5. 4. Flow modeling and bank erosion downstream due to spillway discharge : Independent thesis Advanced level (professional degree) 30 ECTS credits

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Alexander Lindblad; [2022]
   Keywords : Ansys Fluent; Multiphase Flow; Spillway; CFD; Volume of Fluid; Reynolds-averaged Navier-Stokes;

   Abstract : Dam spillways and downstream areas are used to guide large flows of water during for example heavy rainfall. The large flows give way to turbulent pattern sand velocities that may damage the river banks or the dam structure. Investigation of these water patterns at certain flows are therefore done to examine at risk areas. READ MORE

6. 5. Stellar Encounters at the Galactic Centre

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Roberts Fisers; [2022]
   Keywords : Galaxy; encounter; SPH; NSC; Physics and Astronomy;

   Abstract : Using methods of smoothed particle hydrodynamics (SPH) an N -body simulation was set-up to investigate stellar encounters between a 1 solar-mass main sequence (MS) star, modeled after the Sun, and a 0.6 solar-mass white dwarf (WD). This was done primarily to investigate the assumptions made by Mastrobuono-Battisti et al. READ MORE
