mao, R. (author), Yu, S.C.M. (author), Zhou, T. (author), Chua, L.P. (author)Lobe-forced mixer is one typical example of the passive flow controllers owing to its corrugated trailing edge. Besides the spanwise Kelvin–Helmholtz vortex shedding, streamwise vortices are also generated within its mixing layer. The geometrical configuration of the lobe significantly affects these two types of vortices, which in turn affects...journal article 2009

Han, B. (author), Yang, Z. (author), Shi, X. (author), Yu, X. (author)This paper preliminarily investigates the general transport properties (i.e., water sorptivity, water permeability, and gas permeability) of carbon-nanotube/cement composites. Carboxyl multi-walled carbon nanotubes (MWNTs) are dispersed into cement mortar to fabricate the carbon nanotubes (CNTs) reinforced cement-based composites by applying...journal article 2012

Qiu, J. (author), Van de Ven, M. (author), Wu, S. (author), Yu, J. (author), Molenaar, A. (author)The self-healing capability of bituminous materials has been known for many years. Researches were mostly focused on the self healing behaviour during load repetitions. The tests are either time consuming and/or complex. In this paper, a simple self healing test procedure is presented combining the fracture-healing-re-fracture test (FHR) with...journal article 2012

Qiu, J. (author), Molenaar, A.A.A. (author), Van de Ven, M.F.C. (author), Wu, S. (author), Yu, J. (author)Self healing of asphalt mixes is known for more than four decades. However, it is a complex phenomenon which depends on the duration of the rest period, temperature, crack size, etc. In order to quantify the self healing behaviour of asphalt mixes, a test setup was proposed in this research using an asphalt beam on an elastic foundation. Within...journal article 2012

Vuorinen, V. (author), Yu, J. (author), Tirunagari, S. (author), Kaario, O. (author), Larmi, M. (author), Duwig, C. (author), Boersma, B.J. (author)Large-eddy simulations (LES) based on scale-selective implicit filtering are carried out in order to study the effect of nozzle pressure ratios on the characteristics of highly underexpanded jets. Pressure ratios ranging from 4.5 to 8.5 with Reynolds numbers of the order 75?000–140?000 are considered. The studied configuration agrees well with...journal article 2013

Yu, Q. (author), Wang, Y. (author), Gao, J. (author), Gao, S. (author), Flemming, B. (author)Traditionally, vertical circulation (induced by gravity circulation and tidal straining), tidal pumping, and resuspension are suggested as the major processes for the formation and maintenance of the estuarine turbidity maximum (ETM). Due to strong mixing, tidal pumping is considered as the dominating process in macrotidal estuaries. To analyze...journal article 2014

Pinkse, M.W.H. (author), Evaristo, G. (author), Pieterse, M.M. (author), Yu, Y. (author), Verhaert, P.D.E.M. (author)Peptide families are characterized by structural motifs, which often comprise specific post-translational modifications (PTMs) required for biological activity. In conventional bioactivity-based peptidomics studies natural peptide mixtures are chromatographically separated and the bioactive fractions purified to homogeneity, prior to structural...journal article 2014

(author)The identification of clusters or communities in complex networks is a reappearing problem. The minimum spanning tree (MST), the tree connecting all nodes with minimum total weight, is regarded as an important transport backbone of the original weighted graph. We hypothesize that the clustering of the MST reveals insight in the hierarchical...journal article 2015

Yu, Q. (author), Chen, Y. (author), Liu, Z. (author), Van de Giesen, N.C. (author), Zhu, D. (author)Algal blooms have been frequently found at the upper reaches of the Tanglang River, which is downstream from the eutrophic Dianchi Lake. The eutrophic lake upstream is considered to be a potential source of phytoplankton, which contributes to the development of harmful algal blooms in the river downstream and can cause many serious problems for...journal article 2015

Yu, C. (author), You, K (author), Xie, L (author)This paper studies the identification of ARMA systems with colored measurement noises using finite-level quantized observations. Compared with the case under colorless noises, this problem is more challenging. Our approach is to jointly design an adaptive quantizer and a recursive estimator to identify system parameters. Specifically, the...journal article 2016

Yu, W. (author), Ferreira, Carlos (author), van Kuik, G.A.M. (author), Baldacchino, D. (author)Although the Blade Element Momentum method has been derived for the steady conditions, it is used for unsteady conditions by using corrections of engineering dynamic inflow models. Its applicability in these cases is not yet fully verified. In this paper, the validity of the assumptions of quasi-steady state and annuli independence of the blade...journal article 2016
