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

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Jiale Deng; [2023]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

   Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Tanmmay Rout; [2023]
   Nyckelord :Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

   Sammanfattning : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

4. 3. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Zhenyu Li; [2023]
   Nyckelord :mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

   Sammanfattning : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. LÄS MER

5. 4. Parallel Operation of Grid-Forming Power Inverters

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Alessia Camboni; [2023]
   Nyckelord :;

   Sammanfattning : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. LÄS MER

7. 5. Transspråkande som arbetssätt : Om möjligheter och utmaningar med att arbeta transspråkande i grundskolan

   Uppsats för yrkesexamina på grundnivå, Malmö universitet/Institutionen för kultur, språk och medier (KSM)

   Författare :Monica Reinhart; [2023]
   Nyckelord :identitetsutveckling; litteracitetsutveckling; språklig medvetenhet; språkpolicy; transfer;

   Sammanfattning : The aim of this research compilation is to seek further understanding of how translanguaging can be used as a method to assist students learning in Swedish elementary schools. In order to gain understanding I have read and thematically analyzed ten different research studies, eight of them set in a Swedish context, and two international studies from Canada and the Netherlands.
