van den Berg, L. (author), Pronk, M. (author), van Loosdrecht, Mark C.M. (author), de Kreuk, M.K. (author)Granular sludge processes are frequently used in domestic and industrial wastewater treatment. The granule buoyant density and biomass density are important parameters for the design and operation of granular sludge reactors. Different methods to measure the granule density include the pycnometer method, the Percoll density gradient method,...journal article 2022

Toja Ortega, S. (author), van den Berg, L. (author), Pronk, M. (author), de Kreuk, M.K. (author)In aerobic granular sludge (AGS) reactors, granules of different sizes coexist in a single reactor. Their differences in settling behaviour cause stratification in the settled granule bed. In combination with substrate concentration gradients over the reactor height during the anaerobic plug-flow feeding regime, this can result in functional...journal article 2022

van den Berg, D. (author), De Tavernier, D. (author), van Wingerden, J.W. (author)In recent years dynamic induction control has shown great potential in reducing wake-to-turbine interaction by increasing the mixing in the wake. With these wake mixing methods the thrust force will vary in time. If applied to a floating offshore wind turbine, it will cause the platform to move. In this paper the effect of the Helix mixing...journal article 2022

Vermeer, C.M. (author), Depaz, Lena (author), van den Berg, Emily (author), Koelmans, Tom (author), Kleerebezem, R. (author)Medium-chain-length polyhydroxyalkanoate (mcl-PHA) production by using microbial enrichments is a promising but largely unexplored approach to obtain elastomeric biomaterials from secondary resources. In this study, several enrichment strategies were tested to select a community with a high mcl-PHA storage capacity when feeding octanoate. On...journal article 2022

Herrera Semenets, V. (author), Hernández-León, Raudel (author), Bustio-Martínez, Lázaro (author), van den Berg, Jan (author)Telecommunications services have become a constant in people’s lives. This has inspired fraudsters to carry out malicious activities causing economic losses to people and companies. Early detection of signs that suggest the possible occurrence of malicious activity would allow analysts to act in time and avoid unintended consequences. Modeling...conference paper 2022

(author), Kaiser, Elias (author), Vialet-Chabrand, Silvere (author), van der Ploeg, Martine (author), van Emmerik, Tim (author), Coenders-Gerrits, Miriam (author), ten Veldhuis, Marie-claire (author)Plant transpiration accounts for about half of all terrestrial evaporation. Plants need water for many vital functions including nutrient uptake, growth and leaf cooling. The regulation of plant water transport by stomata in the leaves leads to the loss of 97% of the water that is taken up via their roots, to the atmosphere. Measuring plant...book chapter 2022

van den Berg, S.C. (author), Scharff, R.B.N. (author), Rusak, Z. (author), Wu, J. (author)We present OpenFish: an open source soft robotic fish which is optimized for speed and efficiency. The soft robotic fish uses a combination of an active and passive tail segment to accurately mimic the thunniform swimming mode. Through the implementation of a novel propulsion system that is capable of achieving higher oscillation frequencies...journal article 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

van den Berg, M.A. (author), Owen, C.C. (author), Hendrikse, H. (author)This study analyses the results from basin tests with a vertically sided cylindrical pile loaded by ice failing in crushing. Tests were performed with a ‘rigid’ structure and with structural models representing a series of single-degree-of-freedom (SDOF) oscillators covering a wide range of mass, frequency, and damping values. The structural...journal article 2022

(author), van Loon-Steensma, Jantsje M. (author), Meire, Patrick (author)Nature-based strategies, such as wave attenuation by tidal marshes, are increasingly proposed as a complement to mitigate the risks of failure of engineered flood defense structures such as levees. However, recent analysis of historic coastal storms revealed smaller dike breach dimensions if there were natural, high tidal marshes in front of...journal article 2022
