1. Exploring potential E-fuel production pathways for maritime and aviation sectors in France : a techno-economic and environmental assessment
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : 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. READ MORE

2. Computation of Acoustic Wave Propagation Under Water
University essay from KTH/Matematik (Avd.)Abstract : 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. READ MORE

3. A Discrete Cylindrical Luneburg Lens With Liquid Layers
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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. READ MORE

5. Acoustic Source Characterization of a Road
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : 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. READ MORE
