Shi, N. (author), Yang, Y. (author), Niemegeers, I.G. (author)Ultra Wide Band (UWB) has recently gained great interest for high data rate short-range WPANs. Designing a MAC protocol for UWB WPANs must take into account the physical layer characteristics. Due to large bandwidth and spreading spectrum, a time hopping impulse radio UWB (IR-UWB) system can accomplish multiple access by using code division...conference paper 2007

The streamwise and spanwise travelling waves induced by spanwise Lorentz force are studied for skin-friction drag reduction in a turbulent channel. The streamwise travelling wave by spanwise Lorentz force on drag reduction is compared to the with the spanwise wall motion. The drag reduction map shows a drag reduction region and a drag increase...conference paper 2015

Yang, Jingbin (author), Sun, Zhenping (author), Yanliang, Ji (author), Li, Biyun (author), Pang, Min (author)As an internal curing material, superabsorbent polymers (SAPs) can effectively reduce the risk of volume shrinkage of cement-based materials. By preparing the cement paste mixed with SAPs, the amount of pre-absorbed water and the water-cement ratio of paste on the water absorption-release behavior in the fresh cement paste were studied by using...conference paper 2021

Ying, Shen (author), Guo, Renzhong (author), Li, Weiyang (author), Yang, Jie (author), Zhao, Zhigang (author), Li, Lin (author)There are many 3D objects with denser aggregation that they are fully/partly coherent touched with each other through shared facets, which we called coherent set of 3D objects. Visualization for 3D property unit is an effective way to understand 3D spatial occupation, location and relationship in urban space, particularly in the coherent set of...conference paper 2016

Yang, D. (author), Sun, Y. (author), Turrin, M. (author), von Buelow, P. (author), Paul, J.C. (author)Currently, in the conceptual envelope design of sports facilities, multiple engineering performance feedbacks (e.g. daylight, energy and structural performance) are expected to assist architectural design decision-making. In general, it is known as Building Performance Optimization in the conceptual architectural design phase. Essentially, it...conference paper 2015

Yang, J. (author), Hauff, C. (author), Bozzon, A. (author), Houben, G.J.P.M. (author)Collaborative Question Answering (cQA) platforms are a very popular repository of crowd-generated knowledge. By formulating questions, users express needs that other members of the cQA community try to collaboratively satisfy. Poorly formulated questions are less likely to receive useful responses, thus hindering the overall knowledge generation...conference paper 2014

Gu, Chunping (author), Ji, Yongjie (author), Yang, Yang (author), Liu, Jintao (author), Ni, Tongyuan (author)Sewage sludge ash (SSA) is the combustion residue of the sewage sludge obtained from wastewater treatment plants. In China, SSA normally contains high content of SO3, which may cause detrimental effect on the volume stability of cement-based materials. This study investigated the effect of sulfate-rich SSA (SR-SSA) on the volume deformation and...conference paper 2021

Yang, Kai (author), Ye, Guang (author), De Schutter, Geert (author)Water molecules exist as two spin isomers, differing by the relative orientation of the nuclear spins of the two hydrogen atoms: either antiparallel (para-water, S=0) or parallel (ortho-water, S=1) [1]. The transition between these nuclear spin states can be achieved through magnetic symmetry breaking via a field gradient across the spins...conference paper 2021

We investigate the double diffusive convection between two parallel plates with either no-slip or free-slip boundary conditions. Direct numerical simulations have been conducted systematically for a series of control parameters. Salt fingers can be observed for both boundary conditions and all parameters explored. Compared to the no-slip case,...conference paper 2015

Su, H.Z. (author), Wen, Z. (author), Yang, M. (author)The elastic-plastic mechanical behaviour is a typical characteristic of rock mass. The load action will bring on the local destruction, large deformation, even whole failure of rock mass with the discontinuous mediums (e.g. joint, crack and fault). It is a coupling process of the continuous deformation and the discontinuous deformation. The...conference paper 2015

(author)The strain-hardening behaviour of cementitious composites is the result of a synergistic behaviour of the cement matrix and fibres in a cracked cross-section. The distribution and orientation of the fibres are essential in order to obtain such favourable tensile behaviour. Strain-hardening composites can be applied and are especially useftil in...conference paper 2014
