16. Techno-Economic Assessment of High-Temperature H2O/CO2 : Co-Electrolysis in Solid Oxide Electrolysers for Syngas Production
Master-uppsats, KTH/KemiteknikSammanfattning : High-temperature Co-electrolysis of H2O and CO2 in a solid-oxide electrolyser (Co-SOE) for syngas production is a high-efficiency renewable electricity conversion and storage method part of the Power-to-X technologies. Syngas, a mixture of H2, CO and CO2, is a critical building block to make several chemical and synthesis fuels. LÄS MER
17. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.

18. Models for solid waste and its management in Stockholm metropolitan area
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In the transition from a linear economy to a sustainable circular economy, waste management is critical. This thesis approaches the management of Municipal Solid Waste (MSW) from the perspective of a mathematical modelling. Within the scope of the thesis, three mathematical models were developed.

19. CFD Analysis of the Flow Into a Preheater
Master-uppsats, KTH/Teknisk mekanikSammanfattning : This project has investigated and formed a basis for the thermal- and flow-induceddynamic loads in the lower parts of a preheater situated in a nuclear power plant.Special attention has been given to the bottom plate that separates the heated andnon-heated secondary steam.

20. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. LÄS MER
