Miedema, Rene (author), Strydis, C. (author)IntroductionIn-silico simulations are a powerful tool in modern neuroscience for enhancing our understanding of complex brain systems at various physiological levels. To model biologically realistic and detailed systems, an ideal simulation platform must possess: (1) high performance and performance scalability, (2) flexibility, and (3) ease of...journal article 2024

Tan, J. (author), Polinder, H. (author), Jarquin Laguna, A. (author), Miedema, S.A. (author)An adjustable draft point absorber was recently proposed as a novel approach to improve power absorption with constrained power take-off (PTO) capacities. The key feature of the novel wave energy converter (WEC) concept is to adjust the buoy draft by regulating the ballast water inside the buoy, which aims to enable variation of the natural...journal article 2023

Miedema, Daphne (author), Taipalus, Toni (author), Aivaloglou, E.A. (author)Several educational studies have argued for the contextualization of assignments, i.e., for providing a context or a story instead of an abstract or symbolic problem statement. Such contextualization may have beneficial effects such as higher student engagement and lower dropout rates. In the domain of database education, textbooks and...conference paper 2023

Sturge, Jodi (author), Miedema, E. (author), Elf, Marie (author), Nordin, Susanna (author)Introduction: Housing and the ageing population are issues that pose challenges for social, health and economic policies. Therefore, there is a need for more knowledge on how to design housing and public infrastructure to improve the social engagement and well-being of older adults who age in place. This project aims to provide an overview of...review 2023

Tan, J. (author), Tao, W. (author), Jarquin Laguna, A. (author), Polinder, H. (author), Xing, Yihan (author), Miedema, S.A. (author)Wave-to-Wire models play an important role in the development of wave energy converters. They could provide insight into the complete operating process of wave energy converters, from the power absorption stage to the power conversion stage. In order to cover a set of relevant nonlinear effects, wave-to-wire models are predominately...journal article 2023

Taipalus, Toni (author), Miedema, Daphne (author), Aivaloglou, E.A. (author)Querying a relational database is typically taught in practice by using an exercise database. Such databases may be simple toy examples or elaborate and complex schemas that mimic the real world. Which of these are preferable for students is yet unknown. Research has shown that while more complex exercise databases may hinder learning, they...conference paper 2023

Tan, J. (author), Wang, X. (author), Polinder, H. (author), Jarquin Laguna, A. (author), Miedema, S.A. (author)A crucial part of wave energy converters (WECs) is the power take-off (PTO) mechanism, and PTO sizing has been shown to have a considerable impact on the levelized cost of energy (LCOE). However, as a dominating type of PTO system in WECs, previous research pertinent to PTO sizing did not take modeling and optimization of the linear permanent...journal article 2022

Qian, Z. (author), Miedema, Henk (author), de Smet, Louis C.P.M. (author), Sudhölter, Ernst J. R. (author)We investigated in detail the permeation selectivity in the electro-dialysis of Na<sup>+</sup>, K<sup>+</sup>, Mg<sup>2+</sup> and Ca<sup>2+</sup> in both binary and quaternary mixtures using a supported liquid membrane (SLM). The SLM consisted of the organic liquid 2-nitrophenyl octyl ether (NPOE) containing a lipophilic anion, i.e. tetrakis...journal article 2022

Qian, Z. (author), Miedema, Henk (author), Pintossi, Diego (author), Ouma, Marvin (author), Sudhölter, Ernst J. R. (author)High Na<sup>+</sup> levels are detrimental for most crops. Selective membranes provide the possibility for the selective removal of Na<sup>+</sup> while preserving beneficial ion species. The challenge is to separate two ion species of the same charge. This study evaluates the implementation of an electrodialysis (ED) system equipped with a...journal article 2022

de Vrijer, T. (author), Miedema, Sander (author), Blackstone, Thijs (author), van Nijen, D.A. (author), Han, C. (author), Smets, A.H.M. (author)A logical next step for achieving a cost price reduction per Watt peak of photovoltaics (PV) is multijunction PV devices. In two-terminal multijunction PV devices, the photo-current generated in each subcell should be matched. Intermediate reflective layers (IRLs) are widely employed in multijunction devices to increase reflection at the...journal article 2022

Cuevas, Alejandro (author), Miedema, F.E.G. (author), Soska, Kyle (author), Christin, Nicolas (author), van Wegberg, R.S. (author)A number of recent studies have investigated online anony- mous (“dark web”) marketplaces. Almost all leverage a “measurement-by-proxy” design, in which researchers scrape market public pages, and take buyer reviews as a proxy for ac- tual transactions, to gain insights into market size and revenue. Yet, we do not know if and how this method...conference paper 2022

Tan, J. (author), Polinder, H. (author), Jarquin Laguna, A. (author), Miedema, S.A. (author)The Power Take-Off (PTO) rating of Wave Energy Converters (WECs) is generally much higher than the average extracted power. Scientific literature has indicated that downsizing the PTO capacity to a suitable level is beneficial for improving the techno-economic competitiveness. In this paper, a novel design, namely the adjustable draft system,...journal article 2022

Tan, J. (author), Polinder, H. (author), Jarquin Laguna, A. (author), Miedema, S.A. (author)The power take-off (PTO) system is a main component in wave energy converters (WECs), and it accounts for a notable proportion in the total cost. Sizing the PTO capacity has been proven to be significant to the cost-effectiveness of WECs. In the numerical modeling, the PTO size is normally represented by a force constraint. Therefore, to...journal article 2022
