van Gisbergen, Daan (author)This thesis explores waiting and rebalancing strategies in urban waterborne transport, intending to improve the efficiency and operational performance of water transportation systems. The study is based on a review of the literature on waterborne transport and waiting and rebalancing strategies. This is followed by a case study where the found...master thesis 2023

Alhaddad, S.M.S. (author), Mehta, D. (author), Helmons, R.L.J. (author)We present an effective design of a hydraulic, polymetallic nodule collector, which fundamentally depends on the Coandă effect in harvesting nodules. The design was first developed based on 2D numerical simulations conducted using a computational fluid dynamics tool, ANSYS FLUENT. Following that, the design was tested in full-scale experiments,...journal article 2023

Chen, Szu Tung (author), Ermis, G. (author), Sharpanskykh, Alexei (author)Inspired by the vision of fully autonomous airside operations at Schiphol airport, this study aims to contribute to the short-term goal of automated aircraft ground handling. In this research, we design and evaluate a multi-agent system for planning of automated ground handling. There are two main components in the system: task allocation...journal article 2023

Boele, Jelle (author)This thesis describes the design of a CMOS magnetic field sensor system for measuring electronic currents. A hybrid system, using Hall plates and a pick-up loop is chosen to obtain improved performance compared to conventional Hall based magnetic field sensors. The pick up loop enables to reduce the current consumption and increases the...master thesis 2022

Alhaddad, S.M.S. (author), de Jonge, Laurens (author), Boomsma, W.B.A. (author), Helmons, R.L.J. (author)Polymetallic nodules are potato-sized rock accretions that form on vast areas of the abyssal plains of the global ocean. These nodules are rich in commercially precious metals, such as nickel, cobalt and copper, making them a target for potential future deep-sea exploitation. Generally, polymetallic nodules are partially buried in the seabed...conference paper 2022

Maričić, Marko (author)Ride-pooling is a key concept for the future of human mobility and vital in the roll-out of Mobility-as-a-Service (MaaS). Pooling allows individuals to travel at a reduced fare (when comparing to a private alternative) due to the reduction in operating costs as the usage of the vehicles is increased; essentially, the main intentions of pooling...master thesis 2021

Alhaddad, S.M.S. (author)Underwater slope failure is a common problem in the fields of geotechnical, dredging and hydraulic engineering, posing a major risk to submerged infrastructure and flood defences along coasts, rivers, and lakes. The term ‘flow slide’ refers to a specific, complex failure mechanism of underwater slopes, which occurs when a substantial amount of...doctoral thesis 2021

van Alebeek, S.L.F. (author), Bombelli, A. (author)Increased competitiveness with other transport systems and declining operation margins have motivated freight forwarders in the air cargo transport industry to look into horizontal collaboration. This paper focuses on developing a fully integrated five-phase auction-based coopetition model, a form of horizontal collaboration where competition is...journal article 2021

Fielbaum, Andres (author), Bai, X. (author), Alonso-Mora, J. (author)On-demand systems in which passengers with similar routes can share a vehicle are expected to become a relevant part of future mobility, thanks to their flexibility and their potential impact on reducing congestion. Nevertheless, due to the long detours required by a door-to-door scheme, they induce extra costs to the users in terms of delay....journal article 2021

Fielbaum, Andres (author)Within the context of a shared on-demand transport system, we study the problem of selecting the stopping points from which passengers should walk to their exact destinations (or from their exact origins). We focus on the single-vehicle case that must follow a predefined order of requests, posing the mathematical program, showing that it can...journal article 2021

Kosicki, Matthijs (author)The rise of e-commerce makes shopping easier than ever. It also puts pressure on logistic service providers, their employees, traffic and the environment. Parcel deliveries to service points or parcel lockers could release some of this pressure. However, service points are only scarcely used by Dutch consumers, while parcel lockers still lack a...master thesis 2020

Janssens de Bisthoven, Sébastien (author)Automated vehicles have the potential to create a future in which most cars are shared instead of being individually owned and used. The advantages of vehicle sharing are expected to be multiple: reduced traffic, freed-up parking space, safer trips and a lower environmental impact of traveling. The dial-a-ride problem with transfers (DARP-T)...master thesis 2020

van Damme, M. (author)When soil surfaces are exposed to high shear stresses induced by high-velocity water flows, they erode. Erosion consists of the detachment, entrainment and transport of soil particles. When exposed to high shear stresses the process of soil detachment is no longer given by the pick-up of individual particles but by the continuous shear failure...journal article 2020

Alhaddad, S.M.S. (author), Labeur, R.J. (author), Uijttewaal, W.S.J. (author)This paper starts with surveying the state-of-the-art knowledge of breaching flow slides, with an emphasis on the relevant fluid mechanics. The governing physical processes of breaching flow slides are explained. The paper highlights the important roles of the associated turbidity current and the frequent surficial slides in increasing the...journal article 2020

Jiang, J. (author)This Ph.D. dissertation describes the theory and realization of wide-bandwidth magnetic sensors for current measurements which breach the conventional offset and noise constraints in CMOS processes. These are achieved by several circuit-level and system-level innovations, including the use of three orthogonal ripple reduction loops (RRLs) in...doctoral thesis 2019

Mor, A. R. (author), Muñoz Muñoz, F.A. (author), Castro Heredia, L.C. (author)This paper presents a new concept for partial discharge measurements in gas insulated systems (GIS). The proposed technique uses a novel GIS magnetic antenna that measures the magnetic field produced by partial discharges (PD) propagating in GIS. The foundations of the measurement technique and the magnetic antenna design are presented...journal article 2019

Bellan, Daniele (author)Machine learning techniques aim to train a model in such a way that it can approximate complex dynamics like the vehicle routing problem. In the recent years, combinatorial neural networks and deep learning methods have been used to predict the solution of routing problems. However, the approaches investigated so far in literature could be...master thesis 2018

Sickler, Femke (author)The air cargo market is experiencing momentous developments that may impact strongly on future trends. A consolidation shift has been observed, by more integration of the supply chain. Integrators engage in forwarding, forwarding agents operate their own aircraft and airlines bypass the forwarding agents, by striking direct structural deals with...master thesis 2018

Bisschop, F. (author)The safety level of a dike is expressed in terms of risk. Risk is defined as the product of the probability of inundation of a polder (after failure of a dike) and the expected damage (casualties, economic damage and damage to the infrastructure) caused by inundation. The rate of inundation determines the amount of casualties and depends heavily...doctoral thesis 2018

Alves Beirigo, B. (author), Schulte, F. (author), Negenborn, R.R. (author)In the realm of human urban transportation, many recent studies have shown that comparatively smaller fleets of shared autonomous vehicles (SAVs) are able to provide efficient door-to-door transportation services for city dwellers. However, because of the steady growth of e-commerce and same-day delivery services, new city logistics...journal article 2018
