1. Exploring potential E-fuel production pathways for maritime and aviation sectors in France : a techno-economic and environmental assessment
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The aviation and maritime industries pose significant challenges for decarbonization, having increased activity in the past decade. One promising solution to limit emissions in these sectors is Electrofuels (E-fuel), derived from water electrolysis hydrogen and captured CO2 or nitrogen. LÄS MER
2. Computation of Acoustic Wave Propagation Under Water
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : In this thesis we look at acoustic wave propagation under water. We look in particular at waves generated by a point source and what happens with the propagation when we model the bottom as flat or as curvilinear. We assume the source to be working at a certain frequency and therefore we model this problem by solving the Helmholtz equation. LÄS MER
3. A Discrete Cylindrical Luneburg Lens With Liquid Layers
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In this project, a cylindrical Luneburg lens isdesigned operating at optical frequencies. A Luneburg lens isa gradient index lens that transforms a point source into aplane wave or vice versa. The lens is rotational symmetric whichallows wide-angle beam scan. In this work, the gradient indexis discretized in layers. LÄS MER
4. Comparison of direct air capture technology to point source CO2 capture in Iceland
Master-uppsats, KTH/KemiteknikSammanfattning : Det är välkänt att klimatförändringar på grund av global uppvärmning är en av de största kriserna som hotar jorden. Det är en enorm utmaning för mänskligheten att minska koldioxidutsläppen, den främsta orsaken till global uppvärmning. LÄS MER
5. Acoustic Source Characterization of a Road
Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : A road can be considered as a noise source based on its traffic density. Intuition says, a road, with closely spaced vehicles, can be classified as a line source and for sparsely spaced vehicles, a collection of point sources. LÄS MER
