Giraldo, Juan S. (author), Vergara Barrios, P.P. (author), Lopez, Juan Camilo (author), Nguyen, Phuong H. (author), Paterakis, Nikolaos G. (author)Linear optimal power flow (OPF) formulations are powerful tools applied to a large number of problems in power systems, e.g., economic dispatch, expansion planning, state estimation, congestion management, electricity markets, among others. This article proposes a novel mixed-integer linear programming formulation for the ac-OPF of three...journal article 2021

Olindo, Roberta (author), Schmitt, Nathalie (author), Vogtländer, J.G. (author)LCAs of electric cars and electrolytic hydrogen production are governed by the consumption of electricity. Therefore, LCA benchmarking is prone to choices on electricity data. There are four issues: (1) leading Life Cycle Impact (LCI) databases suffer from inconvenient uncertainties and inaccuracies, (2) electricity mix in countries is...journal article 2021

Dekker, R. (author), van der Meer, F.P. (author), Maljaars, J. (author), Sluys, Lambertus J. (author)This study presents calibration and validation of a cohesive extended finite element model for fatigue crack propagation in ductile materials. The approach relies on a separation between plasticity around the crack tip and fatigue crack growth at the crack tip such that the influence of plasticity on fatigue driving forces is predicted. This...journal article 2021

Wu, P. (author), Ferrari, Riccardo M.G. (author), Liu, Y. (author), van Wingerden, J.W. (author)Incipient fault detection plays a crucial role in preventing the occurrence of serious faults or failures in industrial processes. In most industrial processes, linear, and nonlinear relationships coexist. To improve fault detection performance, both linear and nonlinear features should be considered simultaneously. In this article, a novel...journal article 2021

Duval-Arnould, Aude (author), Schröder, Stefan (author), Charton, R.J.G. (author), Joussiaume, Rémi (author), Razin, Philippe (author), Redfern, Jonathan (author)Passive margins are traditionally regarded as tectonically quiescent, however the increasing recognition of significant post-rift tectonic uplift along their flanks offers an important control on sediment delivery. The most extensive record of the early post-rift succession of the Central Atlantic Margin (CAM) is found in the Lower and Middle...journal article 2021

Raju, Narayana (author), Arkatkar, Shriniwas (author), Easa, Said (author), joshi, gaurang (author)The present work introduced a framework of developing comprehensive extended vehicular trajectory data under heterogeneous non-lane-based traffic conditions like the NGSIM datasets in the United States. Due to the absence of automation and instrumentation, and even the lack of sensor deployment on roads in developing economies like India, it...journal article 2021

Muilwijk, Corné (author), van den Akker, H.E.A. (author)This paper describes the effects of uniform and non-uniform liquid co-flow on the bubbly flow in a rectangular column (with two inlets) deliberately aerated unevenly. The two vertical bubbly streams, comprising uniform bubbles, started interacting downstream of the trailing edge of a splitter plate. This study quantifies the emergence of...journal article 2021

Tamis, J. (author), Joosse, B.M. (author), de Leeuw, K.D. (author), Kleerebezem, R. (author)In this study, we investigated the operational performance and product spectrum of glucose-fermenting anaerobic granular sludge reactor at pH 4. A selective environment for the growth of granules was implemented by the introduction of a 2 min settling phase, a hydraulic retention time of 6 h and a solid retention time of 12 ± 3 days. The...journal article 2021

Wandl, Alex (author), Hausleitner, B. (author)A large proportion of European inhabitants live in dispersed urban settlements, much of which is labelled as sprawl, defined by monofunctional, low-density areas. However, there is increasing evidence that this may be an overly simplistic way of describing territories-in-between (TiB). This paper defines and maps functional mix in six...journal article 2021

Kadeethum, T. (author), Lee, S. (author), Ballarin, F. (author), Choo, J. (author), Nick, H.M. (author)This paper presents a mixed finite element framework for coupled hydro-mechanical–chemical processes in heterogeneous porous media. The framework combines two types of locally conservative discretization schemes: (1) an enriched Galerkin method for reactive flow, and (2) a three-field mixed finite element method for coupled fluid flow and...journal article 2021

(author), Lamb, Hildo J. (author), Westenberg, Jos J.M. (author)Fontan patients require a balanced hepatic blood flow distribution (HFD) to prevent pulmonary arteriovenous malformations. Currently, HFD is quantified by tracking Fontan conduit flow, assuming hepatic venous (HV) flow to be uniformly distributed within the Fontan conduit. However, this assumption may be unvalid leading to inaccuracies in HFD...journal article 2021

Nagalur Subraveti, H.H.S. (author), Srivastava, Anupam (author), Ahn, Soyoung (author), Knoop, V.L. (author), van Arem, B. (author)This paper presents a novel approach to improve traffic throughput near diverge and weave bottlenecks in mixed traffic with human-driven vehicles (HDVs) and connected automated vehicles (CAVs). This is done by the strategic assignment of CAVs across lanes. The main principle is to induce strategic and necessary lane changes (LCs) (by CAVs and...journal article 2021

Fang, H. (author), van der Zwaag, S. (author), van Dijk, N.H. (author)A computational 3D model that accounts for both nucleation and interface migration is a very useful tool to monitor and grasp the complexity of microstructure formation in low-alloyed steels. In the present study we have developed a 3D mixed-mode multigrain model for the austenite-ferrite and the austenite-ferrite-austenite formation capable...journal article 2021

Goyal, N. (author), Howlett, Michael (author)Although understanding initial responses to a crisis such as COVID-19 is important, existing research on the topic has not been systematically comparative. This study uses topic modeling to inductively analyze over 13,000 COVID-19 policies worldwide. This technique enables the COVID-19 policy mixes to be characterized and their cross-country...journal article 2021

Quin, T. (author), Limbu, B.H. (author), Beerens, M.J.J. (author), Specht, M.M. (author)Traditional online communications tools used in education are limited in terms of fostering naturalistic or life-like interaction. Such limited interactions in classrooms can negatively impact learning. Holograms are promising tools that show potential to overcome such limitations by affording more life-like interactions in virtual classrooms...journal article 2021

Rafiee, Poorya (author), Ebrahimi, S. (author), Hosseini, M. (author), Tong, Yen Wah (author)The dewatering of algal culture requires coagulation of the algal cells. However, the coagulation in a continuous operation is slowed down through the excretion of Soluble Algal Products (SAPs). Electrocoagulation (EC), already utilized as a coagulation technique, has been investigated for its effects on SAPs characterizations. A mixed...journal article 2020

Varotto, S.F. (author), Farah, H. (author), Bogenberger, Klaus (author), van Arem, B. (author), Hoogendoorn, S.P. (author)Adaptive Cruise Control (ACC) can reduce traffic congestion and accidents. In dense traffic flow conditions and when changing lanes, drivers prefer to deactivate the ACC. These control transitions between automation and manual driving could impact driver behaviour characteristics. However, few studies have analysed the magnitude and duration of...journal article 2020

Lindemulder, N. (author), Veraar, M.C. (author)In this paper we consider the Laplace operator with Dirichlet boundary conditions on a smooth domain. We prove that it has a bounded H<sup>∞</sup>-calculus on weighted L<sup>p</sup>-spaces for power weights which fall outside the classical class of A<sub>p</sub>-weights. Furthermore, we characterize the domain of the operator and derive...journal article 2020

van den Boom, A.J.J. (author), Muijsenberg, Marenne van den (author), De Schutter, B.H.K. (author)In this paper we discuss scheduling of semi-cyclic discrete-event systems, for which the set of operations may vary over a limited set of possible sequences of operations. We introduce a unified modeling framework in which different types of semi-cyclic discrete-event systems can be described by switching max-plus linear (SMPL) models. We use...journal article 2020
