Huang, Z. (author), Wang, Q (author)In this paper, the influence of sodium hydroxide and water glass of various modulus, as activators, on the compressive strength, microstructure and hydration products of two alkali-activated phosphorous slag (AAPS) with different chemical composition were studied. Water glass activation shows relatively higher later compressive strength when the...conference paper 2021

Huang, G. (author), Pitts, B.J. (author)Weather information latency during flight in general aviation (GA) has resulted in numerous incidents. Hands-free automated speech recognition (ASR) systems have the potential to help overcome this challenge and facilitate rapid weatherrelated information exchange. However, it is unclear to what extent ASR systems can support pilot communication...conference paper 2019

Huang, H. (author), Zhang, D. (author)To date, the tunneling in China is experiencing an age of fast development for decades. The potential risks behind the huge amount of construction and operation works in China was first formally realized and managed after 2002. The transition of risk assessment from a qualitative manner to a quantitative manner is on the way from the research...conference paper 2015

Nie, X. (author), Zhang, J. (author), Huang, H. (author), Liu, Z. (author), Lacasse, S. (author)In the past few years, random field theory has been increasingly used to model the inherent soil variability. The scale of fluctuation is one of the important parameters describing a stationary random field. In this study, the factors affecting an accurate estimation of the scale of fluctuation were studied with numerical experiments to show how...conference paper 2015

Xu, H. (author), Yu, M. (author), Huang, H. (author), Fan, Y. (author)The original urban planning can never meet the requirements of the rapid development and the increasing population in big cities in China. The best way to solve this problem is to develop the underground space (including tunnels). With the exhaustion and saturation of the shallow underground space, the development of urban area is more and more...conference paper 2015

Meng, J. (author), Huang, J. (author), Sloan, S.W. (author)Slope instability and landslides can be catastrophic events often leading to loss of life and property. To assess the risks of slope failures, it is often desired that the dynamic process of slope failure can be simulated. This paper proposes a Granular Contact Dynamics (GCD) approach based on variational principles and implicit time integration...conference paper 2015

Griffiths, D.V. (author), Huang, J. (author), Fenton, G.A. (author)Using recently obtained deterministic results as a benchmark, probabilistic slope stability analyses have been performed on an undrained slope using the random finite element method (RFEM). Non-stationary random fields have been generated with linearly increasing mean undrained strength and a constant coefficient of variation. The influence of...conference paper 2015

Intermittency is an ubiquitous property of fully developed turbulence, for Eulerian and Lagrangian fields, and for velocity, passive and active scalars. Intermittency corresponds to multi-scale high fluctuations, with some underlying long-range correlations. Such property is usually characterized using scaling approaches, verified using...conference paper 2015

The interaction of different scales is among the most interesting and challenging features in turbulence research. Existing approaches used for scaling analysis such as structure-function and Fourier spectrum method have their respective limitations, for instance scale mixing, i.e. the so-called infrared and ultraviolet effects. To make...conference paper 2015

The optimal transient growth process in a particle-laden channel flow is studied under the influence of the linear feedback control. The equilibrium Eulerian approach with the assumption that the particles are small and spherical is adopted. The effect of initial distribution of particles on the optimal transient growth of perturbations is...conference paper 2015

(author)In this paper, we propose an approach to autonomously control a quadrotor micro aerial vehicle (MAV). With take-off weight of 50 g and 8-min flight endurance, the MAV platform codenamed KayLion developed by the National University of Singapore (NUS) is able to perform autonomous flight with pre-planned path tracking. The vision-based...conference paper 2014

Huang, H. (author), Ye, G. (author)Since self-healing of cracks is able to improve the durability of concrete structures, it has attracted much attention in the recent years. As known, in concrete matrix there are large amounts of cement grains remaining unhydrated, particularly in high performance concrete. Further hydration of these unhydrated cement grains has potential to...conference paper 2013
