Allaart, M.T. (author), Korkontzelos, Charilaos (author), Sousa, Diana Z. (author), Kleerebezem, R. (author)Syngas fermentation has gained momentum over the last decades. The cost-efficient design of industrial-scale bioprocesses is highly dependent on quantitative microbial growth data. Kinetic and stoichiometric models for syngas-converting microbes exist, but accurate experimental validation of the derived parameters is lacking. Here, we...journal article 2024

van der Werf, Job (author)REAL-time control (RTC) is a technique used to dynamically control urban drainage systems to utilise the existing infrastructuremore optimally. It can be used to achieve a number of objectives aiming to improve the functioning of the urban drainage system, typically through the reduction of pollution. When heavy rainfall occurs, combined sewer...doctoral thesis 2023

Suzuki, T. (author), Altomare, Corrado (author), Willems, Marc (author), Dan, Sebastian (author)Understanding key flooding processes such as wave overtopping and overflow (i.e., water flows over a structure when the crest level of the structure is lower than the water level in front) is crucial for coastal management and coastal safety assessment. In port and harbour environments, waves are not only perpendicular to the coastal...journal article 2023

van der Werf, Job (author), Kapelan, Z. (author), Langeveld, J.G. (author)Model Predictive Control (MPC) of Urban Drainage Systems (UDS) has been established as a cost-effective method to reduce pollution. However, the operation of large UDS (containing over 20 actuators) can only be optimized by oversimplifying the UDS dynamics, potentially leading to a decrease in performance and reduction in users' trust, thus...journal article 2023

Swillus, M. (author), Zaidman, A.E. (author)Software testing is an integral part of modern software engineering practice. Past research has not only underlined its significance, but also revealed its multi-faceted nature. The practice of software testing and its adoption is influenced by many factors that go beyond tools or technology. This paper sets out to investigate the context of...journal article 2023

Zou, P. (author), Kim, Taeksang (author), Bricker, J.D. (author), Uijttewaal, W.S.J. (author)The modelling of complex free surface flows is challenging due to the mobility and deformability of the interface and air entrainment characteristics, which are highly affected by turbulence. With the framework of Reynolds averaged Navier–Stokes (RANS) models and the volume of fluid (VOF) method, turbulence quantities at the air–water...journal article 2023

van der Werf, Job (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, Job (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

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

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

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
