1. 21. Modelling trend cycles of a stock in the market through social transmission

   Master-uppsats, Mälardalens universitet/Utbildningsvetenskap och Matematik

   Författare :Sedigheh Nemati; [2023]
   Nyckelord :Social finance; Fashion cycles; Stock market; Cultural evolution; Simulation; Population model.;

   Sammanfattning : This project investigates the relationship between social interactions among marketparticipants and the emergence of cyclical trends in stock markets. Two models aredeveloped to capture the interaction dynamics among individuals within the market:a basic model and a model with a price mechanism. LÄS MER

3. 22. Computational Analysis of Spray Deflector Designs

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Osman Gyokhan Ali; [2023]
   Nyckelord :Planing Hulls; Spray Deflector; Hull Modification; Computational fluid dynamics CFD ; resistance; trim angle; heave; CD-adapco Star CCM ; Numerical Ventilation; Phase Replacement; Modified HRIC Scheme; Volume Fraction Source Term; Reynolds averaged Navier-Stokes RANS ; Volume of Fluid VOF ; SST K-Omega Turbulence Modelling; Höghastighetshantverk; modelldesign; spraydeflektor;

   Sammanfattning : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. LÄS MER

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

   Magister-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

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

   Sammanfattning : 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. LÄS MER

5. 24. Numerical study of a jet impacting a heated object

   Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Författare :Moutaz Hammoud; [2023]
   Nyckelord :Numerical model; COMSOL Multiphysics; Heat transfer; Impinging jets.;

   Sammanfattning : Heat transfer brought about by impinging jets is common in several industrialapplications such as the cooling of heated objects. The purpose of this investigationis to create a numerical model of an impacting jet, then to use it in parametricresearch and in the cooling of an electronic device. LÄS MER

7. 25. Numerical Simulations of Metal Recovery for Battery Recycling

   Master-uppsats, KTH/Processteknologi

   Författare :Morgan Ölander; [2023]
   Nyckelord :Batteriåtervinning; Metall återvinning; Kristallisation; Computational Fluid Dynamics CFD ; Populationsbalansmodellering; Battery recycling; Metal recovery; Crystallisation; Computational Fluid Dynamics CFD ; Population balance modelling;

   Sammanfattning : Den pågående elektrifieringen av transport och samhälle kräver utveckling av nya metoder för återvinning av batterier. Hydrometallurgi som fokuserar på selektiv kristallisation av metaller är ett intressant alternativ för dessa ändamål. Dessa system kan studeras genom modellering och simulering. LÄS MER
