Kramer, O.J.I. (author), van Schaik, C. (author), Dacomba Torres, P.D.R. (author), de Moel, P.J. (author), Boek, E.S. (author), Baars, E.T. (author), Padding, J.T. (author), van der Hoek, J.P. (author)Granular activated carbon (GAC) filtration is an important unit operation in drinking water treatment. GAC filtration is widely used for its filtration and adsorption capabilities as a barrier for undesired organic macro- and micro-pollutants. GAC filtration consists of two successive phases: adsorption and filtration, capturing the impurities...journal article 2021

Hermans, T.H.J. (author), Gregory, Jonathan M. (author), Palmer, Matthew D. (author), Ringer, Mark A. (author), Katsman, C.A. (author), Slangen, Aimée B.A. (author)The effective climate sensitivity (EffCS) of models in the Coupled Model Intercomparison Project 6 (CMIP6) has increased relative to CMIP5. We explore the implications of this for global mean sea-level (GMSL) change projections in 2100 for three emissions scenarios. CMIP6 projections of global surface air temperature are substantially higher...journal article 2021

Câmara, Arthur (author), Roy, N. (author), Maxwell, D.M. (author), Hauff, C. (author)Web search engines are today considered to be the primary tool to assist and empower learners in finding information relevant to their learning goals- be it learning something new, improving their existing skills, or just fulfilling a curiosity. While several approaches for improving search engines for the learning scenario have been proposed...conference paper 2021

Chuang, Jia Shian (author)This research aims to develop a method to create a wind farm layout that is robust against the uncertainty source, the inter-year variation of Weibull parameters and wind direction sector probabilities. A wind farm layout optimisation problem under uncertainty corresponds to optimisation under uncertainty (OUU), which is computationally...master thesis 2020

Steinebach, Koen (author)In proton therapy, robust treatment planning is currently used to account for uncertainties in patient alignment and proton beam range. A way to overcome the limitations of robust treatment planning is to use probabilistic treatment planning, which can be computationally expensive due to the calculations of statistical measures of stochastic...master thesis 2020

Bruins Slot, Hilco (author), Nugteren, Alex (author), van Rie, Victor (author), Nota, Hugo (author), Overgaauw, Tim (author), van der Heide, Niels (author)This report is written with the aim to evaluate a possible port expansion in the port of San Vicente, Chile. In order to achieve this a thorough analysis on the port operations, hydrodynamical analysis using Delft3D and a bottleneck analysis on the infrastructure have been executed. A preliminary design for the port expansion is created. This...student report 2020

Analikwu, Brendan (author)In this thesis, an algorithm to model the magnetic perturbation field caused by ships is designed and implemented. A systematic description of methods used for modelling the magnetic signature of ships is given. The algorithm fits coefficients of a prolate spheroidal harmonic expansion of the scalar potential of the magnetic field using a least...bachelor thesis 2020

Sindy, F. (author)In this thesis the water motion and sediment dynamics are investigated in a periodically closed and opened estuary. The water motion in an estuary is mainly driven by the semi-diurnal tide with an period of 12h25m and river discharge. An example of such an estuary is the Ems-Dollard estuary. Recent observations show an increase in tidal range ...bachelor thesis 2020

Blok, S.A.W. (author)In financial and egineering problems, we are often faced with solving Partial-Integro Differential Equations (PIDEs). Rarely we can find an analytic solution in a closed form expression for these PIDEs, hence we turn to numerical schemes to accurately approximate the solution instead. Classically these methods are based on finite difference...bachelor thesis 2020

van Dijk, Jeroen (author)Little to no research has been done on the multi-agent path finding with waypoints problem (MAPFW) even though it has many important real world applications. In this paper we extend an existing algorithm for the multi-agent path finding problem (MAPF) called M* \cite{New}. We do so by ordering the waypoints using a Travelling salesman problem...bachelor thesis 2020

Calon, Rob (author)Motivations for sustainability are initiating an energy transition that is changing the European energy domain. The transition effectuated the adaptation of large volumes of wind and solar based generation capacity. The intermittent power-output of these Variable Renewable Energy Sources challenges the balancing operation of the electricity...master thesis 2020

Sforzi, Riccardo (author)Venezia, la Serenissima. The most serene Republic. One adjective is sufficient to identify the city of Venice; more complicated is to figure out its singularities: the city of canals, trades, cultural exchange, gate between the west and the east, the city of the myth, the romantic city, the city of the endless descriptions. “At once solid and...master thesis 2020

Schmits, Jeroen (author)Dipoles are all around us and the extent to which it is possible to distinguish two dipoles next to each other is a very important criterion for optical resolution. This report proposes that the resolution can be enhanced by placing a substrate with a film underneath the dipoles. This report specifically looks at the effect on the near and far...bachelor thesis 2020

Nering Bögel, Meyke (author)In 2018, the number of forcibly displaced people all over the world was higher than ever before. More than a third of this group are refugees, often living in refugee camps. NGOs try to deliver all necessary aid to these camps, while facing limited access and resources. Therefore, they want to optimize the results of the aid they deliver. The...master thesis 2020

Shekhar, A. (author)Energy transition will inevitably lead to greater electrification. For example, it is anticipated that electrical energy demand will rise by at least 2-3 times by 2050 with increasing share of electric vehicles and heat pumps. This will translate to significant increase in power demand on the existing medium voltage distribution grid, resulting...doctoral thesis 2020

Santanoceto, M. (author), Tiberga, M. (author), Perko, Z. (author), Dulla, Sandra (author), Lathouwers, D. (author)Uncertainty Quantification (UQ) of numerical simulations is highly relevant in the study and design of complex systems. Among the various approaches available, Polynomial Chaos Expansion (PCE) analysis has recently attracted great interest. It belongs to non-intrusive spectral projection methods and consists of constructing system responses...conference paper 2020

Kongshaug, Simen Sørgaard (author), Oseland, Oddbjørn (author), Kanstad, Terje (author), Hendriks, M.A.N. (author), Rodum, Eva (author), Markeset, Gro (author)The alkali silica reaction (ASR) in concrete causes internal localized swelling and micro cracking, which result in expansion and correlated deterioration of the concrete material. The stress state of the concrete is known to affect expansion due to ASR, with an anisotropic stress state giving rise to anisotropic expansion. Similarly, the...journal article 2020

Anand, N. (author), Colonna, Piero (author), Pini, M. (author)Supersonic stator vanes account for two-thirds of the fluid-dynamic losses in high temperature mini-Organic Rankine Cycle (ORC) turbines. As a result, the overall performance of the turbo-expander mainly depends on the design of the stator. Currently, there is no established correlation for the optimal design of such cascades. This work...journal article 2020

(author)Hybrid ac-dc distribution systems with multiple parallel operating ac and dc links are being developed to maximize system capacity during (n-1) contingencies. This paper shows that offline reconfigurability between such ac and dc links post-fault clearance allows an additional design flexibility of reducing the required substation converter...journal article 2020

Jonker, Hendrik (author)Since the liberalization of the energy markets, the storage of energy is decoupled from the production and sales. In Western-Europe the storage of natural gas becomes more and more important because production fields get depleted and governments force companies to slow down their production because of tremors in the ground. Natural gas needs to...master thesis 2019
