Diambra, A. (author), Corti, R. (author), Liu, H. (author), Pisano, F. (author), Abell, J. A. (author)This paper presents an objective comparison between two recent constitutive models employing the concept of the hardening memory surface to predict the high cyclic loading behaviour of granular soils. The hardening memory surface is applied to the well-known Severn-Trent sand and the SANINSAND04 constitutive models. While the addition of the new...conference paper 2019

Zeng, Ningshuang (author), Liu, Y. (author), Mao, Chao (author), König, Markus (author)Environmental burdens arise in the whole life cycle of construction. Waste and pollution are produced in the upstream and downstream of a construction project along the supply chains. The interdependency between on-site construction and off-site logistics also leads to an expansion effect of waste when a disturbance occurs. A related supply...journal article 2018

Liu, H. (author)Digital elevation models (DEM) are widely used in various distributed hydrological models. The stream network can be extracted from it so that runoff routing can be calculated. With the advent of remote sensing and computing technologies, the computation based on DEM with high resolution becomes possible. However, there still exist regions with...conference paper 2018

Aravinthan, Visvakumar (author), Balachandran, Thanatheepan (author), Ben-Idris, Mohammed (author), Fei, Wanghao (author), Heidari-Kapourchali, Mohammad (author), Hettiarachchige-Don, Anton (author), Liu, Chen-Ching (author), Stefanov, Alexandru (author), Tindemans, Simon H. (author)Power system operation considering an increasingly complex cyber infrastructure may be one of the key factors of the next generation power systems. The effective operation of a power system in a massively deployed cyber network environment will be affected by cyber network reliability. Therefore, it is vital not only to understand the operation...conference paper 2018

Filonenko, G.A. (author), Lugger, Jody A.M. (author), Liu, C. (author), van Heeswijk, Ellen P.A. (author), Hendrix, Marco M.R.M. (author), Weber, Manuela (author), Müller, Christian (author), Hensen, Emiel J.M. (author), Sijbesma, Rint P. (author), Pidko, E.A. (author)Structural heterogeneity defines the properties of many functional polymers and it is often crucial for their performance and ability to withstand mechanical impact. Such heterogeneity, however, poses a tremendous challenge for characterization of these materials and limits our ability to design them rationally. Herein we present a practical...journal article 2018

Ma, M. (author), Liu, K. (author), Shen, J. (author), Kas, R. (author), Smith, W.A. (author)In this work, the highly selective and stable electrocatalytic reduction of CO<sub>2</sub> to CO on nanostructured Ag electrocatalysts is presented. The Ag electrocatalysts are synthesized by the electroreduction of Ag<sub>2</sub>CO<sub>3</sub> formed by in situ anodic-etching of Ag foil in a KHCO<sub>3</sub> electrolyte. After 3 min of this...journal article 2018

Liu, L. (author), Liu, S. (author), Popov, M. (author)The widely acknowledged high-voltage direct current (HVDC) technology has now been accepted as a solution of connecting renewable energy sources. However, this technology is vulnerable when facing DC-side faults; due to<br/>the low DC impedance, the fault current can rise to an extremely high value in a short time. In addition, when building a...journal article 2018

(author), Cheng, Lin (author), Liang, Xuan (author), To, Albert. C. (author)Manufacturing-oriented topology optimization has been extensively studied the past two decades, in particular for the conventional manufacturing methods, for example, machining and injection molding or casting. Both design and manufacturing engineers have benefited from these efforts because of the close-to-optimal and friendly-to-manufacture...journal article 2018

Peng, B. (author), Xu, Y. (author), Liu, Kai (author), Wang, Xiaoqun (author), Mulder, F.M. (author)Black phosphorus (BP) has received increasing research attention as an anode material in sodium-ion batteries (SIBs), owing to its high capacity, electronic conductivity, and chemical stability. However, it is still challenging for BP-based SIB anodes to achieve a high electrochemical performance utilizing cost-effective materials and...journal article 2017

Apostolidis, P. (author), Liu, X. (author), Kasbergen, C. (author), Scarpas, Athanasios (author), van de Ven, Martin (author)Induction technology was introduced to the paving industry to assist pavement operations by heating asphalt layers efficiently from the surface. Many experimental studies have been conducted to investigate the impact of inductive particles on the heating efficiency of asphalt mixes. However, research is limited on the quantification of design,...journal article 2017

Liu, Y. (author), Mol, J.M.C. (author), Janssen, G.C.A.M. (author)The aluminium alloy 7075-T6 is widely used in engineering. In some applications, like slurry transport, corrosion and abrasion occur simultaneously, resulting in early material failure. In the present work, we investigated the combined effect of corrosion and wear on the aluminium alloy 7075-T6. We performed two series of wear experiments to...journal article 2016

Liu, J. (author), Quadvlieg, Frans (author), Hekkenberg, R.G. (author)The profile of a ship rudder influences the forces it generates, which in turn influence the manoeuvring performance of a ship. Thus, rudder forces and moments should be calculated considering the profile. Instead of an empirical estimation of the rudder normal force coefficient, this paper applies a RANS method to determine the hydrodynamic...journal article 2016

Liu, J. (author), Hekkenberg, R.G. (author)In order to reach the required manoeuvrability, inland vessels often use twin rudders, but the interaction effects are poorly understood. To achieve a proper configuration, this paper applies 2D RANS simulations to analyse the interaction effects on the twin-rudder hydrodynamics. Various twin-rudder configurations with different profiles and...conference paper 2016

The behavior of particles in compressible turbulence has been seldom investigated to date despite its importance in many natural and industrial flows. Direct numerical simulations of particle-laden compressible isotropic turbulence are performed to study the preferential concentration of particles and the underling mechanisms. It turns out that...conference paper 2015

Liu, Y. (author), Arntsen, B. (author), Wapenaar, C.P.A. (author), Van der Neut, J.R. (author)The virtual source method has been applied successfully to retrieve the impulse response between pairs of receivers in the subsurface. This method is further improved by an updown separation prior to the crosscorrelation to suppress the reflections from the overburden and the free surface. In a reversed situation where the sources are in the...conference paper 2014
