Orie, Nicolaas (author)This thesis develops dynamical state-space models of the oil market and suggests opportunities for the application of control theory. The emphasis of this thesis is on the modelling, rather than the control theory applications. Most models that are currently employed by oil companies do not model short-term transient responses, but focus on long...master thesis 2020

Mueller, Michiel (author), Wiegmans, B. (author), van Duin, Ron (author)European container ports compete in partially overlapping hinterland areas. The objective of this study is to model port choice and obtain insight into port choice decisions for European container imports from Asia. The importance of port choice factors and their impact on port market shares in the hinterland were investigated. Furthermore,...journal article 2020

van Vliet, Oscar (author), Hanger-Kopp, Susanne (author), Nikas, Alexandros (author), Spijker, Eise (author), Carlsen, Henrik (author), Doukas, Haris (author), Della Santina, C. (author)Identifying the risks that could impact a low-carbon transition is a prerequisite to assessing and managing these risks. We systematically characterise risks associated with decarbonisation pathways in fifteen case studies conducted in twelve countries around the world. We find that stakeholders from business, government, NGOs, and others...journal article 2020

Jansen, K.M.B. (author), Zhang, M. F. (author), Ernst, L. J. (author), Vu, D. K. (author), Weiss, L. (author)In this paper we propose a new multistep characterisation method to be able to map out the dependency of moisture diffusion parameters of a polymeric material over a range of temperature and humidity conditions in a limited amount of time. We do that by (1) using a moisture sorption analyser which can continuously monitor weight changes with...journal article 2020

Abdelrady, Ahmed (author), Sharma, Saroj (author), Sefelnasr, Ahmed (author), El-Rawy, Mustafa (author), Kennedy, M.D. (author)Bank filtration (BF) is acknowledged as a sustainable and effective technique to provide drinking water of adequate quality; it has been known for a long time in Europe. However, this technique is site-specific and therefore its application in developing countries with different hydrologic and environment conditions remains limited. In this...journal article 2020

van Duin, Ron (author), Wiegmans, B. (author), van Arem, B. (author), van Amstel, Y.A. (author)E-commerce is still a strong growing segment with fierce competition among parcel delivery service providers. To stay ahead of the competitors innovation is necessary. Currently, parcels are being delivered with large delivery vans which will usually deliver single parcels to doorsteps of their customers. This so called 'last mile delivery'...journal article 2020

Li, Z. (author), Lu, T. (author), Liang, X. (author), Dong, H. (author), Ye, G. (author)This study aims to provide a better understanding of the autogenous shrinkage of slag and fly ash-based alkali-activated materials (AAMs) cured at ambient temperature. The main reaction products in AAMs pastes are C-A-S-H type gel and the reaction rate decreases when slag is partially replaced by fly ash. Due to the chemical shrinkage and the...journal article 2020

(author)Phase-Contrast Magnetic Resonance Imaging (PC-MRI) surpasses all other imaging methods in quality and completeness for measuring time-varying volumetric blood flows and has shown potential to improve both diagnosis and risk assessment of cardiovascular diseases. However, like any measurement of physical phenomena, the data are prone to noise,...journal article 2020

Mulder, W.A. (author)Simulations of wave propagation in the Earth usually require truncation of a larger domain to the region of interest to keep computational cost acceptable. This introduces artificial boundaries that should not generate reflected waves. Most existing boundary conditions are not able to completely suppress all the reflected energy, but suffice...journal article 2020

Mulder, W.A. (author)The representation of a force or moment point source in a spectral finite-element code for modelling elastic wave propagation becomes fundamentally different in degenerate cases where the source is located on the boundary of an element. This difference is related to the fact that the finite-element basis functions are continuous across...journal article 2020

Lu, T. (author), Li, Z. (author), van Breugel, K. (author)In recent decades, several simulation models have been proposed to predict autogenous shrinkage of cementitious systems. In most of these models, however, only the elastic deformation caused by self-desiccation of the hydrating cement paste is considered. In fact, cement paste is not an ideal elastic material. Also the time-dependent...journal article 2020

van Bilsen, Daniël (author), Huang, Yilin (author), Li, Fen (author)China is undergoing large changes to tackle carbon dioxide emissions and air pollution. While the top-down governance allows for clear setting of emission reduction targets for industrial sectors and major cities, reducing emissions in residential sectors in smaller (the so-called low-tier) cities remain challenging and often unaddressed.

Boricic, Aleksandar (author), Rueda, José L. (author), Popov, M. (author)Renewable energy sources (RES) penetrate power grids at all voltage levels. A large number of RES units are connected to medium-voltage (MV) and low-voltage (LV) levels resulting in a significant share of overall generation. Therefore, the dynamic behavior of such distribution grids should be thoroughly examined. The goal of this paper is to...conference paper 2020

Wallace, Mark (author), Yorke-Smith, N. (author)The cyclic hoist scheduling problem (CHSP) is a well-studied optimisation problem due to its importance in industry. Despite the wide range of solving techniques applied to the CHSP and its variants, the models have remained complicated and inflexible, or have failed to scale up with larger problem instances.

van Meurs, Bram (author)Floods cause major problems around the world. Over 35 million people were affected by floods in 2018. They have a growing worldwide impact on life and property. Changes in climate conditions lead to unanticipated variations in glacial runoffs, snowmelt and precipitation, which all significantly changing river flows. An imbalance in river network...master thesis 2019
