van der Werf, J.A. (author), Kapelan, Z. (author), Langeveld, J.G. (author)Model Predictive Control (MPC) of combined sewer systems can reduce environmental degradation caused by uncontrolled overflows. However, practical uncertainties are often neglected when assessing the potential of MPC strategies. This paper aims to understand the risks associated with using a non-perfect internal MPC-model, real precipitation...journal article 2023

van der Werf, J.A. (author), Kapelan, Z. (author), Langeveld, J.G. (author)Urban Drainage Systems can cause ecological and public health issues by releasing untreated contaminated water into the environment. Real-time control (RTC), augmented with rainfall nowcast, can effectively reduce these pollution loads. This research aims to identify key dynamics in the nowcast accuracies and relate those to the performance...journal article 2023

Roozendaal, Philip (author)Software Question & Answer platforms such as Stack Overflow allow users to annotate their posts with tags in order to help organize them and aid in their discoverability. This work sets out to study the machine learning techniques used to determine these tags automatically, and see how, and to what extent, these determinations could be...bachelor thesis 2022

Botocan, Cristian (author)The users of the most widespread Software Engineering dedicated forum, Stack Overflow (SO), are confronted by the issue of posting duplicate questions and spending time waiting for an answer. Currently, only the SO users with a high reputation and the moderators manually determine this type of post. Hence, an automatic solution can save...bachelor thesis 2022

Hugtenburg, S. (author), Zaidman, A.E. (author)Community Question Answering (CQA) platforms like Stack Over- flow enable gamified and moderated community-driven knowledge creation. We report on our experiences of introducing Stack Over- flow in our Computer Science BSc programme and explore whether these platforms can (1) reduce the workload of lecturers in answer- ing questions in large...conference paper 2022

Rosin, T. R. (author), Kapelan, Z. (author), Keedwell, E. (author), Romano, M. (author)Blockages are a major issue for wastewater utilities around the world, causing loss of service, environmental pollution, and significant cleanup costs. Increasing telemetry in combined sewer overflows (CSOs) provides the opportunity for near real-time data-driven modelling of wastewater networks. This paper presents a novel methodology,...journal article 2022

Buitelaar, Maarten (author), Rademaker, Rolf (author), Lengkeek, Robert (author), Wever, Jason (author)In this assignment we simulate a two meters wide dike stretch which is subjected to overflow. Three failure mechanisms could occur due to overflow: full erosion of the soil of the dike, macro instability of the levee if too much soil is eroded away, leading to insufficient counterweight on the inside of the levee, and surface slip failure due to...student report 2021

An, J. (author), Ra, Jong Hyun (author), Kang, E. (author), Pertijs, M.A.P. (author), Han, S.H. (author)This article presents a readout integrated circuit (ROIC) for capacitive touch-screen panels (TSPs) employing an amplitude-modulated multiple-frequency excitation (AM-MFE) technique. To prevent charge overflow, which occurs periodically at the beat frequency of the excitation frequencies, the ROIC modulates the amplitude of the excitation...journal article 2021

Rosin, T. R. (author), Romano, M. (author), Keedwell, E. (author), Kapelan, Z. (author)Combined Sewer Overflows (CSOs) are a major source of pollution and urban flooding, spilling untreated wastewater directly into water bodies and the surrounding environment. If overflows can be predicted sufficiently in advance, then techniques are available for mitigation. This paper presents a novel bi-model committee evolutionary...journal article 2021

Lottman, Bas (author)A numerical model is developed in Simulink to simulate transient alkaline electrolyzer operation. The model is built to simulate a large scale hydrogen plant in Rjukan, Norway. The model is based on physical relations where available, some plant-specific data is modeled using empirical equations. The model describes the anodic and cathodic...master thesis 2020

Rook, Lars (author)The erosion resistance of clay is an important aspect when assessing the integrity of a levee. This is because the clay layer of a dike must resist the forces that are imposed in the case of overflow or overtopping. Currently, the erosion resistance of clay in the Netherlands is being assessed based on the sand content, the liquid limit and the...master thesis 2020

Markov, Iliya (author), Bierlaire, Michel (author), Cordeau, Jean François (author), Maknoon, M.Y. (author), Varone, Sacha (author)We solve a rich routing problem inspired from practice, in which a heterogeneous fixed fleet is used for collecting recyclable waste from large containers over a finite planning horizon. Each container is equipped with a sensor that communicates its level at the start of the day. Given a history of observations, a forecasting model is used to...journal article 2020

Tims, Frido (author)Already since the start of civilisation dredging is carried out to create and maintain waterways and ports or to create new land. In recent times the scale of dredging and awareness of potential environmental impact of dredging have increased drastically. An often used dredging vessel is the trailing suction hopper dredger (TSHD). A TSHD pumps...master thesis 2019

Cangga Putra, Reynaldi (author)DTB Multiplexer is a component within an NXP chip called the BAP3. This component provides a testing functionality for the chip. This component is purely combinational, and requires no clock, however this makes the component wiring-costly. This high wiring requirement leads to the area constraint imposed by the wiring demand rather than cell...master thesis 2019

(author)The pathways and watermass transformation of the North Icelandic Irminger Current (NIIC) in the Nordic Seas are investigated by tracing the NIIC watermass in two ocean circulation models: the Modular Ocean Model (MOM) and the Parallel Ocean Program (POP). The two simulations use identical atmospheric forcing and have a horizontal resolution of 0...journal article 2019

Torres Alves, Gina (author)Before the Spanish conquest of Mexico, around the year 1519, the Valley of Mexico was a closed basin. As a result, at the bottom of the valley, an extensive system of shallow lakes, lagoons, and swamps was formed due to precipitation and permanent river’s discharge from the Sierra Nevada mountains. This lacustrine system occupied around 1000km2...master thesis 2018

Mahmoodian, M. (author), Carbajal, Juan Pablo (author), Bellos, Vasilis (author), Leopold, Ulrich (author), Schutz, Georges (author), Clemens, F.H.L.R. (author)Urban drainage modelling typically requires development of highly detailed simulators due to the nature of various underlying surface and drainage processes, which makes them computationally too expensive. Application of such simulators is still challenging in activities such as real-time control (RTC), uncertainty quantification analysis or...journal article 2018

Keizer, Kasper (author)The role of water storages at greenhouses will change in the future due to three trends in climate change, upscaling of greenhouses and changes in regulations. These three trends force the local water authority and the greenhouse sector to anticipate on future problems. First step in this process is to understand the hydrological response of...master thesis 2017
