1. 1. Pulse-width voltage modulation in the Python-based open-source simulator Motulator : A Realization of SVPWM, Harmonic analyzer and Over-modulation on Two and Three-level Inverters, and a Solution for Unbalanced Neutral Point Voltage on Three-level Inverters

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

   Author : Jiale Deng; [2023]
   Keywords : Three-level inverters; over-modulation techniques; space vector modulation; neutral-point voltage balancing; non-uniform Fourier transform; Trenivåväxelriktare; övermodulation; spacevektormodulering; balansering av nollpunktsspänning; olikformig Fouriertransform;

   Abstract : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. READ MORE

   Abstract : Recommendation system benefits social media by attracting users with the posts they prefer. The recommended posts, however, may not align with what users really need to browse, especially in terms of emotion. READ MORE

6. 5. The Ext-Algebra of Standard Modules of Bound Twisted Double Incidence Algebras

   University essay from Uppsala universitet/Algebra, logik och representationsteori

   Author : Mika Norlén Jäderberg; [2023]
   Keywords : Algebras; Finite-dimensional; Partially ordered sets; Modules; Quasi-hereditary; Ext-algebra; Schur algebra; Quiver; Path algebra; Categories; Morita equivalence; Yoneda product; Standard module; Homological algebra; Cohomology; Anick Chains;

   Abstract : Quasi-hereditary algebras are an important class of algebras with many appli-cations in representation theory, most notably the representation theory of semi-simple complex Lie-algebras. Such algebras sometimes admit an exact Borel sub-algebra, that is a subalgebra satisfying similar formal properties to the Borel sub-algebras from Lie theory. READ MORE
