Bryan, Lotte (author)Emission of ammonia and nitrogen oxides puts pressure on vulnerable ecosystems in The Netherlands. Satellite data from TROPOMI and CrIS gives vertical column density (VCD) maps for nitrogen dioxide and ammonia respectively. The Flux-Divergence method converts a VCD map to an emission map, by temporally averaging the divergence of the flux of the...master thesis 2022

Crossman, Genya (author)Scientific computing and applied mathematics enable the exploration of and, sometimes even, the simplification of complex systems through various optimized modeling and simulation methods. These fields create and utilize computational resources to do so. Many problems, however, are still unsolvable or very difficult to solve with current well...master thesis 2022

Vos, Roel (author)As a response to the dry summer of 2018, Witteveen+Bos developed a model for water demand prediction to improve insight into water demands. Validation by water board "Hunze en Aas" has revealed the predictive power of the irrigation model to be very limited. For this thesis project, we developed a methodology for the detection of irrigation of...master thesis 2022

O'Hara, Kian (author)In light of our depleting fossil fuel reserves and the relatively `cheap' extraction of oil and in spite of the highly nonlinear nature of reservoirs, waterflooding has become big business. In recent times, the use of numerical reservoir simulation has not only become possible but has increasingly been used in the petroleum industry in the...master thesis 2021

Ye, Ni (author)In this thesis, sensitivity analysis is used to study the influences of parameters on specific outputs in the hydrodynamic model 3D DCSM-FM of the North Sea. The sensitivity analysis is the study of how uncertainty in the outputs of a model can be divided and allocated to different sources of uncertainty in its inputs. The software Delft3D FM is...master thesis 2021

Mol, Maaike (author)The need for accurate estimation of hydrodynamic and water quality model variables arises from the UNITED project, which aims to create high-resolutional forecasting systems for monitoring the cultivation of seaweed and flat oysters and operating of the Belgian pilot of UNITED in the coastal area of the North Sea. Accurate observations of...master thesis 2021

Leegwater, Marjolein (author)Ammonia (NH3) is an important chemical compound in the nitrogen cycle. Ammonia is an essential nutrient and an important part of fertilizer, which in soil leads to increased growth of crops. However, the current excess of NH3 emissions is a hazard to environmental and human health. While ammonia<br/>emissions need to be reduced, the emission...master thesis 2021

van Leeuwen, Bodine (author)When building a convolutional neural network, many design choices have to be made. In the case of Deepfake detection, there is no readily implementable recipe that guides these choices. This research aims to work towards understanding the effects of design choices in the case of Deepfake detection, using the Python library Keras and publicly...master thesis 2020

Zijlker, Tammo (author)This study aims to improve estimates of NOx emission strengths by assimilation of TROPOMI satellite retrievals in the LOTOS-EUROS chemical transport model. Nitrogen oxides (NO and NO2) play a pivotal role in atmospheric chemistry, are an important source of air pollution and contribute to nitrogen deposition over vulnerable natural areas....master thesis 2020

Fick, I.S.A. (author)Al ruim een half jaar houdt het de hele wereld in zijn greep: het Corona virus. Waar we dachten dat het allemaal begon als een onschuldige griep, werd al snel duidelijk dat er meer aan de hand was. Wuhan kampte al een tijdje met dit onbekende virus en op 23 januari 2020 werd het zelfs zo serieus dat de Chineese overheid een lockdown afkondigde...bachelor thesis 2020

Jagt, Declan (author)Although a transition to more sustainable energy production is necessary, fossil fuels will remain a crucial contributor to the world's energy production in the near future. In numerically maximizing the production of these fuels, as well as in many other optimization problems, an objective function has to be optimized on the basis of an input...master thesis 2020

Jongbloed, Henk (author)Reliable and efficient modelling of magnetic hysteresis in inhomogeneous and aniso-tropic media is an important step in developing a state-of-the-art closed-loop degaussing system for naval ships and submarines, to be developed by TNO and to be used by the Royal Netherlands Navy in an updated generation of naval vessels and submarines. Different...master thesis 2019

van der Maesen, Bibianne (author)<br/>Though the commercialisation of nanotechnology began only 30 years ago, it has developed into one of the fastest growing industries in terms of research and design, with an unlimited amount of possibilities that will transform industries from how we know them today. The advancement of nanotechnology relies on the actual production, control...master thesis 2018

Burgers, Elsje (author)The growing amount of plastic pollution in the oceans is worldwide a huge problem. There is an increasing amount of projects that try to clean up this pollution. To remove the pollution efficiently, it is useful to know how plastic litter moves, degrades and sinks. Models are being developed that can describe what happens with plastic in the...bachelor thesis 2018

Schaaphok, Marianne (author)This research presents a data-driven model for the magnetic signature of an object, consisting of linearly reacting isotropicmaterial. From magnetostatics mathematical-physical model is derived for the linear behaviour of the induced magnetization. Data-driven updates for the permanent magnetization are computed from comparisons of the computed...bachelor thesis 2018

Markensteijn, G.C. (author)Floods are a big problem for Jakarta; the capital of Indonesia is subsiding below mean sea level and floods will become more frequent. Flood protection and measures against subsidence are, therefore, of high importance to Jakarta’s government. One of the options they are studying is a great sea wall to regulate the water levels in Jakarta Bay....master thesis 2017

de Kloet, Q. (author)There has been a lot of research done into traffic on roads and multiple traffic models have been set up for this type of traffic. A subject that has been largely neglected is the traffic on fairways. The research goal set for my graduation project is to define a model that can simulate the traffic on fairways and use this model to optimize the...master thesis 2016

Van Harmelen, A. (author)Reservoir characteristics such as size and permeability are often non-trivial, which is why sophisticated yet often time-intensive numerical models are commonly used in the Closed-Loop Reservoir Management of subsurface reservoirs in order to maximize profit from oil production. For certain reservoirs, however, simple analytical models can...master thesis 2016
