Ensing, Jorick (author)Travelers do not like transfers in their Public Transport journey; it gives a disutility. Minimizing this disutility is valuable to increase travelers' satisfaction. To be able to reduce this disutility, transfers have to be identified first. Multi-operator smart card datasets allow for the identification of transfers between different operators...master thesis 2022

Denissen, P.J. (author), Homborg, A.M. (author), Garcia, Santiago J. (author)In this work a diffusion-driven inhibitor transport model is used to help in the design of inhibitor-loaded carriers for anticorrosive primers. The work focuses on inhibitor release at damaged locations of different dimensions exposed to electrolyte and is validated experimentally. The damage dimensions are first simulated to determine the...journal article 2022

Lopez Restrepo, S. (author)In order to avoid the adverse effects of air pollution, efforts have been made to monitor when air pollution reaches dangerous levels. A Chemical Transport Model (CTM) can simulate trace gases and particles concentration in specific areas. These models are not entirely reliable, owing to incomplete knowledge about emissions and meteorological...doctoral thesis 2021

Pudane, B. (author)Automated vehicles (AVs) have been a dream for a long time. From science fiction in the 1930s to countless prototypes, extensive road testing, and first use cases at present, the technology has clearly come a long way. So too has the vision of practitioners and academics matured to recognise the various potential benefits (e.g., accessibility,...doctoral thesis 2021

Chen, X. (author), Sanchez, T. (author), Conciatori, D. (author), Chaouki, H. (author), Sorelli, L. (author), Selma, B. (author), Chekired, M. (author)This paper presents a new 2D water transport model considering capillary suction to predict the water content evolution in the concrete porosity. The basic formulations of the model are illustrated, and a switching algorithm is introduced to simulated wet-drying effects. Two specific absorption tests are studied to validate this model. The first...conference paper 2021

Larsen, R.B. (author), Baksteen, Ruud (author), Atasoy, B. (author), Negenborn, R.R. (author)Container transport requires real-time control and a high degree of cooperation to alleviate disturbances and perform smoothly without unnecessary environmental impact and monetary losses. The involved operators are, however, often reluctant to cooperate as they fear loosing valuable information and autonomy, eventually leading their clients...journal article 2021

Data Assimilation as a Tool to Improve Chemical Transport Models Performance in Developing CountriesLopez Restrepo, S. (author), Yarce Botero, A. (author), Quintero Montoya, O.L.

(author), Nino-Ruiz, Elias David (author), Anderson Flórez, Jimmy (author), Rendón, Angela Maíra (author), Alvarez-Laínez, Monica Lucia (author), Heemink, A.W. (author)Particulate matter (PM) is one of the most problematic pollutants in urban air. The effects of PM on human health, associated especially with PM of ≤2.5μm in diameter, include asthma, lung cancer and cardiovascular disease. Consequently, major urban centers commonly monitor PM2.5 as part of their air quality management strategies. The Chemical...book chapter 2021

(author)In this paper, we propose an efficient and practical implementation of the ensemble Kalman filter via shrinkage covariance matrix estimation. Our filter implementation combines information brought by an ensemble of model realizations, and that based on our prior knowledge about the dynamical system of interest. We perform the combination of...journal article 2021

Davydenko, Igor Y. (author), Tavasszy, Lorant (author), Quak, Hans (author)Several studies show that logistics facilities have spread spatially from relatively concentrated clusters in the 1970s to geographically more decentralized patterns away from urban areas. The literature indicates that logistics costs are one of the major influences on changes in distribution structures, or locations and usage of logistics...journal article 2021

van der Tuin, M.S. (author), Pel, A.J. (author)Transport infrastructure owners are moving from reactive toward proactive infrastructure management. This involves computation of costs associated with failure or maintenance, including expected transport delays.

Zhou, Jianchao (author)Stability of dikes is a national security issue for densely populated low-lying countries situated in delta areas, like the Netherlands. One of the dominant dike failuremechanisms in the Netherlands is piping, where high seepage flow rates transport sand particles and subsequently form a ’pipe’ under a dike structure. As such, one manner to...doctoral thesis 2020
