Preliminary sizing methodologies for regional aircraft with liquid hydrogen fuel and SOFC-GT-Battery hybrid-electric powertrains

Solid Oxide Fuel Cell (SOFC) systems for aviation applications have been considered for their use as APUs or powertrains, as standalone systems or in combination with gas turbines, and both fueled by reformed Jet-A or by hydrogen. Most existing studies focus on powertrain performance modelling. In this work, traditional tube-and-wing regional...

An interactive design tool for urban planning using the size of the living space as unit of measurement

In urban planning, one of the common units of measurement for population density is the amount of households per hectare. However, the actual size of the households is seldom considered, neither in 2D nor in 3D. This thesis proposes a method to calculate the average size of the households from existing urban areas based on available open data...

Data analysis, processing and interpretation from different sources: satellites, ground sensor, citizens measurements and municipalities, to fight against building subsidence

Every day, terabytes of information is generated, filling storage devices around the world. However,the human brain have limited capacities to read and understand raw data from a computer screen.That is why data specialists need to ingeniously create better ways to display, process and analyzemassive amounts of data.Our research project is not...
