Buist, J.F.H. (author), Sanderse, B. (author), Dubinkina, S. (author), Oosterlee, C. W. (author), Henkes, R.A.W.M. (author)In this paper we present a complete framework for the energy-stable simulation of stratified incompressible flow in channels, using the one-dimensional two-fluid model. Building on earlier energy-conserving work on the basic two-fluid model, our new framework includes diffusion, friction, and surface tension. We show that surface tension can...journal article 2024

Bley, Eoinlee (author)Mechanical computing systems have historically faced challenges in efficiently integrating computation and memory functions, often leading to complex designs and limited scalability in applications ranging from micro-electromechanical systems (MEMS) to programmable matter. This study aims to address this issue by introducing a mechanical system...master thesis 2023

Offerman, Celine (author)Correctly processing accumulated information is beneficial for our survival. Berghman and Hekkert (2017) argue that this is why we humans derive pleasure from having a sense of aesthetics. These aesthetic experiences can be seen as our brain’s reward system for correctly perceiving and interpret- ing the world around us. While our senses have...master thesis 2023

Kotturshettar, Sanath (author)Stratified turbulent flows abound in environmental and industrial settings. Examples are atmospheric boundary layer flows, the transport of nutrients and organisms and the mixing of heat and salinity in the oceans, fluid flow in heat exchangers, and the transport of reactants and products in chemical reactions. These examples and many others...master thesis 2023

Thabet, Omar (author)Traditional type-checking programs are typically designed for specific programming languages, re- sulting in complex and tightly coupled imperative implementations. One of the challenges faced by type checkers is ensuring consistent name-binding resolution in the presence of new names and sym- bols added to the environment. To address this issue...bachelor thesis 2023

Elaref, Mahmoud (author)Synthetic art is the end result of artificial intelligence models that have been trained to generate images from text prompts. "Comic synthesis" is one such use case, where comic illustrations are produced from textual descriptions. Previous attempts at comic synthesis have utilized conditional Generative Adversarial Networks (cGANs), but this...bachelor thesis 2023

Poulsen, C.B. (author), Zwaan, A.S. (author), Hübner, Paul (author)An important aspect of type checking is name resolution — i.e., determining the types of names by resolving them to a matching declaration. For most languages, we can give typing rules that define name resolution in a way that abstracts from what order different units of code should be checked in. However, implementations of type checkers in...conference paper 2023

Yang, X. (author), Guo, Fucheng (author), Liu, Tao (author), He, Qiang (author), Vymazal, Jan (author), Chen, Yi (author)Ammonia-oxidizing microorganisms (AOMs, archaea (AOA) and bacteria (AOB)) are primarily responsible for the ammoxidation in constructed wetlands (CWs). However, little is known about evaluating the response of AOA and AOB to engineered nanomaterials (ENMs) and quantifying the shift of their contribution to ammoxidation. Herein, we operated a...journal article 2023

(author), Schoppach, Remy (author), Klaus, Julian (author)Identifying the vegetation and topographic variables influencing the isotopic variability of xylem water of forest vegetation remains crucial to interpret and predict ecohydrological processes in landscapes. In this study, we used temporally and spatially distributed xylem stable water isotopes measurements from two growing seasons to examine...journal article 2023

Papoulidou, Sofia (author)Concrete elements, partially or entirely prefabricated are becoming more and more popular in engineering practice. The biggest challenge in this process is the realization of connections between components. These connections fall within two categories: Precast-to-precast connections with hardened parts and<br/>precast-to-in situ connections,...student report 2022

van de Krol, Bart (author)The most used RANS-model in relation to wind farms, k−epsilon, has significant shortcomings. It over-predicts the eddy viscosity in the near-wake and fails to model the anisotropy of the turbulence quantities. The Sparse Regression of the Turbulence Stress Anisotropy (SpaRTA) method could remedy these shortcomings. This method uses temporally...master thesis 2022

Hulst, Naomi (author)Parkinson’s Disease (PD) is the fastest growing neurodegenerative disease, currently affecting two to three percent of the population over 65. Studying functional connectivity (FC) in PD patients may provide new insights into how the disease alters brain organization in different subjects. We explored persistent homology (PH) as a method for...master thesis 2022

Zhang, Y. (author)Multi-stable beam-type metastructures exhibiting snap-through behavior have been extensively studied in recent years , as their stable states can be maintained without the need of external power supply. By arranging a series of beams exhibiting bi-stability, multi-stable metastructures can be constructed. However, current designs of multi-stable...doctoral thesis 2022

van Belzen, Jim (author), Fivash, Gregory S. (author), Hu, Zhan (author), Bouma, T.J. (author), Herman, P.M.J. (author)The establishment of young organisms in harsh environments often requires a window of opportunity (WoO). That is, a short time window in which environmental conditions drop long enough below the hostile average level, giving the organism time to develop tolerance and transition into stable existence. It has been suggested that this kind of...journal article 2022

Yao, Y. (author), Huang, Yunkai (author), Peng, Fei (author), Dong, J. (author), Zhu, Zichong (author)This article proposes a discrete-time dynamic-decoupled current controller for an LCL-equipped high-speed permanent magnet synchronous machine with only the motor currents measured. The controller is designed in the synchronous coordinate based on a complex z-domain transfer function. The main contribution of the proposed current controller...journal article 2022

Zhang, Y. (author), Tichem, M. (author), van Keulen, A. (author)Metastructures composed of snapping beams are capable of deforming into a series of stable states, enabling them to realize shape reconfigurations. In this paper, we present the design of a metastructure-based morphing surface that is able to exhibit a series of stable configurations with different curvatures. Using theoretical, numerical,...journal article 2022

Singh, Chandrakant (author), van der Ent, R.J. (author), Wang-Erlandsson, Lan (author), Fetzer, Ingo (author)Forest and savanna ecosystems naturally exist as alternative stable states. The maximum capacity of these ecosystems to absorb perturbations without transitioning to the other alternative stable state is referred to as ‘resilience’. Previous studies have determined the resilience of terrestrial ecosystems to hydroclimatic changes...journal article 2022
