Duran, J.M. (author)A chronicled approach to the notion of computer simulations shows that there are two predominant interpretations in the specialized literature. According to the first interpretation, computer simulations are techniques for finding the set of solutions to a mathematical model. I call this first interpretation the problem-solving technique...journal article 2019

Tang, J. (author), Vincent-Bonnieu, S.Y.F. (author), Rossen, W.R. (author)We present a CT coreflood study of foam, both pre-generated and generated in-situ, displacing oil, as a function of oil type and saturation. Foam generation and propagation are reflected through sectional pressure measurements. Dual-energy CT imaging monitors in-time phase saturations. With an oil less harmful to foam (hexadecane), injection...journal article 2019

Yang, Jun (author), Wang, X. (author), Baldi, S. (author), Singh, Satish (author), Fari, S. (author)This paper discusses the design and software-in-the-loop implementation of adaptive formation controllers for fixed-wing unmanned aerial vehicles (UAVs) with parametric uncertainty in their structure, namely uncertain mass and inertia. In fact, when aiming at autonomous flight, such parameters cannot assumed to be known as they might vary...journal article 2019

van Hooft, J.A. (author), Baas, P. (author), van Tiggelen, Maurice (author), Ansorge, Cedrick (author), van de Wiel, B.J.H. (author)We present a conceptual model for the diurnal cycle of the dry atmospheric boundary layer (ABL). It may serve as a framework for future numerical studies on the transitional dynamics that characterize the ABL over land. The conceptual model enables us to define expressions for relevant physical scales as a function of the most prominent...journal article 2019

van Beinum, A.S. (author), Wegman, F.C.M. (author)Over the years the characteristics of traffic on Dutch motorways has changed, but its design guidelines did not develop as rapidly and large parts remain unchanged since the first guidelines from the 1970s. During the latest revision of the Dutch motorway design guidelines it became clear that a solid and comprehensive theoretical, or...journal article 2019

van Dijk, J.P.G. (author), Vladimirescu, A. (author), Babaie, M. (author), Charbon-Iwasaki-Charbon, E. (author), Sebastiano, F. (author)A quantum computer comprises a quantum processor and the associated control electronics used to manipulate the qubits at the core of a quantum processor. CMOS circuits placed close to the quantum bits and operating at cryogenic temperatures offer the best solution for the control of millions of qubits. The performance requirements of the...conference paper 2019

Mukherjee, S. (author), Safdari, Arman (author), Shardt, Orest (author), Kenjeres, S. (author), van den Akker, H.E.A. (author)We perform direct numerical simulations (DNS) of emulsions in homogeneous isotropic turbulence using a pseudopotential lattice-Boltzmann (PP-LB) method. Improving on previous literature by minimizing droplet dissolution and spurious currents, we show that the PP-LB technique is capable of long stable simulations in certain parameter regions....journal article 2019

(author)Knowledge on the kinetics of gas hydrate dissociation in microporous sediments is very important for developing safe and efficient approaches to gas recovery from natural gas hydrate (NGH) deposits. Herein, molecular dynamics (MD) simulations are used to study the dissociation kinetics in microporous sediments. The hydrate phase occupies a...journal article 2019

(author)Background: Laparoscopic suturing can be technically challenging and requires extensive training to achieve competency. To date no specific and objective assessment method for laparoscopic suturing and knot tying is available that can guide training and monitor performance in these complex surgical skills. In this study we aimed to develop a...journal article 2019

Gao, P. (author), Ye, G. (author), Wei, J. (author), Yu, Q. (author)The HYMOSTRUC3D model has been used successfully to predict hydration and microstructure development of pure Portland cement paste. In recent years, a number of numerical models were proposed for optimizing the use of supplementary cementitious materials. Also HYMOSTRUC3D was extended for simulating the hydration and microstructure development...journal article 2019

Kuijpers, A.G.J. (author), Lukosch, Heide (author), Verbraeck, A. (author)In this paper we explore the possibilities to combine two research methods we regard as being very useful when interacting with stakeholders in complex systems. We discuss a mixed research methods approach, based on the Q methodology and a simulation game. In a game design process, translating the real or reference system into the game design is...conference paper 2019

Santbergen, R. (author), Uzu, Hisashi (author), Yamamoto, Kenji (author), Zeman, M. (author)We use simulations to optimize perovskite/silicon tandem solar cells in a novel three-terminal configuration, with one terminal at the front and two at the rear. We consider configurations in which the top cell has either the inverted or the same polarity as the bottom cell. Our goal is to minimize the optical losses, to compare the...journal article 2019

Fu, X. (author)Quantum computers can accelerate solving some problems which are inefficiently solved by classical computers, such as quantum chemistry simulation. To date, quantum computer engineering has focused primarily at opposite ends of the required system stack: devising high-level programming languages and compilers to describe and optimize quantum...doctoral thesis 2018

Varotto, S.F. (author)Adaptive Cruise Control (ACC) and automated vehicles can contribute to reduce traffic congestion and accidents. Field operational Tests have shown that drivers may prefer to deactivate ACC systems that are inactive at low speeds in dense traffic conditions and before changing lanes. These transitions between automated and manual driving are...doctoral thesis 2018

Zhang, R. (author), Zijlema, Marcel (author), Stive, M.J.F. (author)In this paper, the ability of the numerical phase resolving model SWASH (Simulating WAves till SHore) to hindcast wave-induced longshore currents is evaluated. Using default settings for all processes modelled, highly accurate results are found for wave heights, mean water levels and longshore currents. While wave current interaction is...journal article 2018

Keuten, M.G.A. (author)As swimmers enter a swimming pool, they release micro-organisms, particles and soluble substances. While chlorine is often used to inactivate micro-organisms, a side-effect of chlorination is the formation of unwanted disinfection by-products. In order to reduce these by-products, more knowledge is needed on the release of pollutants by bathers...doctoral thesis 2018
