Recalde Moreno Del Rocio, M.D.R. (author)The global market for the wastewater treatment industry has been compelled to devise new concepts due to several factors. Currently, approximately 80% of untreated wastewater is discharged worldwide. The conventional technology for municipal solid waste treatment, which has been in use for over a century, is only partially effective in terms of...doctoral thesis 2024

Hariharan Sudha, S. (author), Ragno, E. (author), Morales Napoles, O. (author), Kok, M. (author)The Netherlands has traditionally focused on managing flood risk. However, the frequent occurrence of droughts in recent years has brought attention to managing both extremes. Transitions between these opposite extremes pose additional challenges to water management, requiring a trade-off between water storage during dry periods and flood...journal article 2024

Brancaccio, Marina (author)The ever-increasing power demand, the high scarcity of fossil fuel resources and the growing environmental pollution have pushed the development on technologies related to sustainable energy systems. Maximizing the energetic performance of industrial processes is a key aspect in this quest for sustainable<br/>energy management. A large share of...master thesis 2023

(author), Wang, Xiuqi (author), Pourandi, Sahar (author), Weinhart, Thomas (author)In this paper we introduce the open-source code MercuryDPM: a code for simulating discrete particles. The paper discusses software and management issues that may be interesting for the developers of other open-source codes. Then we review the new features that have been added since the last publication: an improved Hertz-Mindlin model; a new...journal article 2023

Tong, Liang-yu (author), Xiong, Qing Xiang (author), Zhang, Zhidong (author), Chen, Xiangsheng (author), Ye, G. (author), Liu, Qing feng (author)This paper develops a novel lattice diffusive model to quantitatively study the chloride diffusion coefficient in unsaturated cementitious materials, in which the pore voxels are redistributed to make a better representation of a real microstructure of hardened cement paste. Considering the hierarchical microstructure and different drying...journal article 2023

Stoeten, Victor (author)Floods and droughts, also known as hydro-hazards, are phenomena that generally involve detrimental consequences to society and environment. Traditional practices for risk assessment consider flood and drought independently. However, they are two opposite extremes of the same hydrological cycle. Omitting their interaction might lead to an under-...master thesis 2022

Li, Wei (author), Yi, Liming (author), Jiang, Wen (author), Dong, H. (author), Zhang, Yong (author)This paper presents experimental investigations into the effects of ultrafine blast furnace slag on microstructure improvements against chloride penetration in saturated and unsaturated cementitious systems exposed to cyclic drying–wetting conditions. The hydration kinetics of ultrafine slag powders and pore solution chemistry in slag-blended...journal article 2022

Stelling, G.S. (author)The widespread availability of high-resolution Digital Elevation Models (DEM), has led to the development of subgrid numerical modeling techniques, based on Shallow Water Equations (SWE). Detailed DEM data is clustered as much as possible within a coarse grid cell that is preferably much larger than a raster pixel. This has considerable...journal article 2022

(author)The resistance of cracked ECC against chloride ingress is mainly governed by the accumulated crack width of all the cracks rather than the maximum width of multiple cracks. However, most studies focus on the influence of a single fine crackjournal article 2022

Zhao, H. F. (author), Jommi, C. (author)Peats are encountered in waterlogged deltaic areas, where degradation is delayed by favourable environmental conditions. The recent increase in frequency and severity of droughts is expected to accelerate peat degradation, in turn increasing subsidence and flood risk, urging better understanding of the response of peats to drying events. To...journal article 2022

Jongerius, Camiel (author)The study of adhesion mechanisms in animals such as the gecko has helped mankind with the understanding and development of novel adhesives. The adhesion mechanism of the tree frog is not fully understood, it is a wet adhesion mechanism which works differently than the dry adhesion mechanisms of animals, such as the gecko, studied previously. The...master thesis 2021

La Zara, D. (author)The majority of pharmaceutical products is made of solid powders. The morphology and surface characteristics of drug particles affect both their bulk behaviour, e.g., flowability, dispersibility and tabletability, in the manufacturing process of dosage forms as well as their bioavailability upon administration into the human body. For instance,...doctoral thesis 2021

Antonova, Anna (author), Eik, Marika (author), Punkki, Jouni (author), Jokinen, Ville (author), Puttonen, Jari (author)The performance of fibre reinforced cementitious composites depends on the interaction between the cementitious matrix and the fibres on the micro-scale. This interaction is affected by the material and surface properties of the fibre and the micro-scale characteristics of the cementitious matrix close to the fibre surface, creating the...conference paper 2021

Li, X. (author)A flexible riser is a multi-layered pipe device which enables deep-water production by connecting seabed facilities to floating vessels. To withstand huge hydro-static pressure, it is required to have strong collapse capacities. At present, the collapse capacity of a flexible riser is designed based on a "wet collapse'' concept, in which the...doctoral thesis 2021

Li, X. (author), Jiang, X. (author), Hopman, J.J. (author)Flexible risers are designed with strong anti-collapse capacities which enable them to operate in deep-water reservoirs. However, this anti-collapse capacity is susceptible to the pipe curvature in the flooded annulus condition. For the curved riser sections within the touch-down zone, significant reduction of collapse capacity can occur once...journal article 2021
