1. 1. Robo-Advisor portfolioperformance : Studying the effects of building an efficientportfolio from Value at Risk, ExpectedShortfall and Mean-Variance optimization

   Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

   Författare :Tobias Brännvall; Stella El Masry; [2022]
   Nyckelord :Fintech; Robo-advisory; Innovation;

   Sammanfattning : In this research we conduct an in-depth examination of the several financial theories as well asevaluating different implementations of a hypothetical Robo-advisor and the correspondingperformance under market stress (COVID-19). Thus, we contribute a view on Robo-advisors’ benefitsand limitations, providing a foundation for better understanding its potential. LÄS MER

3. 2. Source Term Estimation in the Atmospheric Boundary Layer : Using the adjoint of the Reynolds Averaged Scalar Transport equation

   Master-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Brännvall Tobias; [2015]
   Nyckelord :CFD; Source; Source term; STE; RANS; k epsilon; Adjoint; Adjoint equation; Reynolds transport equation; transport equation; adjoint of transport equation; Adjoint duality;

   Sammanfattning : This work evaluates whether the branch of Reynolds Averaging in Computational Fluid Dynamics can be used to, based on real field measurements, find the source of the measured gas in question. The method to do this is via the adjoint to the Reynolds Averaged Scalar Transport equation, explained and derived herein. LÄS MER
