Limitations and Opportunities of Noisy Quantum Devices

In this work, we first analyse a theoretical technique based on entropic inequalities, which in principle can be used to compare classical and quantum algorithms running on noisy quantum devices. The technique has been used in the past for depolarizing noise, and has shown that for NISQ variational quantum algorithms (VQAs) to give an advantage...

Generating consistent triangular terrain elevation data for noise modelling: Master thesis Geomatics

In 2016, a collaboration between the TU Delft, RIVM and a few other companies started to automate the generation of environmental input data for noise modelling.<br/>As a part of that cooperation a promising triangle based data structure is researched to represent terrain elevation.<br/>Due to the properties of its generation it can provide...

Assessment of an aircraft propeller noise model by verification and experimental validation

The need to contribute to a sustainable future of the aviation industry has spiked an interest in turboprop engines. This is due to the higher propulsive efficiency, the better take-off and landing performance on short runways, and the new developments in propeller-driven hybrid and electric aircraft. The most significant drawback is the noise...

Using NOMOS measurements to assess improvements of ECAC Doc. 29 aircraft noise calculations

The amount of air traffic worldwide is increasing, with an adverse effect on aircraft noise in the vicinity of airports as a result. Measurements and calculations have complementary benefits and limitations for the assessment of aircraft noise. A common method for the calculation of aircraft noise is ECAC Doc. 29. Various improvements of this...

Dutch Aircraft Noise Model: Classification comparison with measurements

In this thesis research, dutch aircraft noise model (NRM) calculations are compared to measurements to analyze the aircraft classification used in the model. To do so, a new implementation of the model has been set up to calculate with LVNL trackdata and NOMOS measurement data. First, the classification approach is analyzed as prescribed, which...

Re-sil(i)ence, aircraft noise abatement by the built environment in the vicinity of airports

The graduation research focusses on mitigations in the built environment abating aircraft noise which can used by urban planners, designers and policy makers operating in airport regions. Aircraft noise is an issue for airport regions as it forces building restrictions upon aircraft noise exposed areas (e.g. for Schiphol and the Amsterdam...
