van den Brule, Yannick (author)The knowledge of the raindrop size distribution is key for characterizing precipitation. It is however still a challenge to retrieve it with radars. Several polarimetric and spectral techniques are proposed for cm-wavelength radars (weather radars). What about the mm-wavelength radars (cloud radars), which have a better spatial and time...master thesis 2022

de Bruijn, Douwe S. (author), ten Eikelder, Henricus R.A. (author), Papadimitriou, V. (author), Olthuis, Wouter (author), van den Berg, Albert (author)The assessment of particle and cell size in electrical microfluidic flow cytometers has become common practice. Nevertheless, in flow cytometers with coplanar electrodes accurate determination of particle size is difficult, owing to the inhomogeneous electric field. Pre-defined signal templates and compensation methods have been introduced to...journal article 2022

Zhang, Y. (author), Wu, Kai (author), Yang, Zhengxian (author), Ye, G. (author)Reliable characterization of the pore structure is essentially important for transport-related durability studies of cementitious materials. Mercury intrusion porosimetry has been commonly used for pore structure measurement while the ink-bottle effect significantly affects the trustworthiness of pore size features of cementitious materials....journal article 2022

Song, Y. (author), de Jong, W.M. (author), Stead, D. (author), Yang, Wei (author), Wang, B. (author)Sustainable urban transformation has become a mantra for Chinese cities. While most studies focus on sustainable urbanization in megacities, the far larger number of medium-sized cities is understudied, although the latter face more severe urban problems. This article develops a framework for examining policy change in sustainable urban...journal article 2022

Periodic structures for melting enhancement: observation of critical cell size and localized meltingZhao, Chunrong (author), Opolot, Michael (author), Liu, Ming (author), Wang, Ji (author), Bruno, Frank (author), Mancin, Simone (author), Hooman, K. (author)The use of metallic periodic structures was considered for melting rate enhancement of a phase change material (PCM) contained in a rectangular enclosure isothermally heated from the side. The critical (optimized) cell size, or pore size, of a periodic structure with fixed porosity, realising the shortest melting time by maximizing the...journal article 2022

Viseu Cardoso, Rodrigo (author)This paper asks whether meaningful differentiations between small and medium-sized cities – “regional second cities” – can be constructed based on their demographic composition, and how these cities differ among each other and from core cities. We investigate 64 regional second cities in eight British city-regions, based on the demographic...journal article 2022

Van den Steen, N. (author), Gonzalez Garcia, Y. (author), Mol, J.M.C. (author), Terryn, H.A. (author), Van Ingelgem, Y. (author)A new approach is proposed to numerically predict and study atmospheric corrosion for ranging droplet size distributions and the influence of the droplet geometry. The proposed methodology allows for a corrosion prediction based on observed droplet size distributions and droplet contact angles. A mechanistic finite element model, including...journal article 2022

Yilmaz, A. (author), He, X. (author), Pletincx, Sven (author), Hauffman, Tom (author), Sietsma, J. (author), Gonzalez Garcia, Y. (author)The role of prior austenite grain size (PAGS) on the passive layer properties of martensitic steels is studied. Electron backscatter diffraction analysis shows that PAGS between 5 and 66 µm were obtained after applying different heat treatments. The barrier properties of passive film deteriorate with grain refinement up to 28 µm, attributed to...journal article 2022

Bais, Frank (author), van der Neut, J.R. (author)Cliff’s Delta is a non-parametric effect size that is based on data observations. In this paper, we elaborate on an adaptation of Cliff’s Delta in order to compare behaviour profiles. Behaviour profiles are density distributions in which survey answer behaviour is summarized for specific groups of respondents or items. Such profiles are...journal article 2022

Implementation of Ship Hybridisation: Sizing a Hybrid Crew Transfer Vessel Considering UncertaintiesKaragiorgis, S. (author), Nasiri, S. (author), Polinder, H. (author)Interest in ship hybridization has increased as a result of policies to combat climate change and boost energy independence. However, designing and optimizing hybrid propulsion systems is a challenging task. The availability of numerous power, propulsion, and energy system topologies with different energy storage and conversion technologies...journal article 2022

(author)Abstract: Pseudaminic and legionaminic acids are a subgroup of nonulosonic acids (NulOs) unique to bacterial species. There is a lack of advances in the study of these NulOs due to their complex synthesis and production. Recently, it was seen that “Candidatus Accumulibacter” can produce Pse or Leg analogues as part of its extracellular...journal article 2022

Mokveld, T.O. (author), Al-Ars, Z. (author), Sistermans, Erik A. (author), Reinders, M.J.T. (author)In prenatal diagnostics, NIPT screening utilizing read coverage-based profiles obtained from shallow WGS data is routinely used to detect fetal CNVs. From this same data, fragment size distributions of fetal and maternal DNA fragments can be derived, which are known to be different, and often used to infer fetal fractions. We argue that the...journal article 2022
