J. Zhang, Auteur ; J.-M. Zhang, Auteur ; Wilson H. Tang, Auteur |As any model is only an abstraction of the real world, model uncertainty always exists. The magnitude of model uncertainty is important for geotechnical decision making. If model uncertainty is not considered, the geotechnical predictions and he[...]

N. K. Othman, Auteur ; J. Zhang, Auteur ; D. J. Young, Auteur |Model Fe–Cr alloys containing 9, 17 or 25 wt% Cr were subjected to repeated 1 h cycles of exposure at 700 °C to flowing gas mixtures of Ar-20O2, Ar-20O2-5H2O and Ar-5O2-20H2O (all in volume %) for up to 400 cycles. The kinetics and morphological[...]

J. Zhang, Auteur ; Wilson H. Tang, Auteur ; J.-M. Zhang, Auteur |Back-analysis of slope failure is often performed to improve one's knowledge on parameters of a slope stability analysis model. In a failed slope, the slip surface may pass through several layers of soil. Therefore, several sets of model paramet[...]

Q. Wu, Auteur ; J. Zhang, Auteur ; D. J. Young, Auteur |The metal dusting behaviour of total 11 nickel- and cobalt-base alloys at 680 °C in a gas of 68%CO[BOND]31%H2[BOND]1%H2O (aC = 19.0, equation image = 5.4 × 10−25 atm) was investigated. All samples were electropolished and reacted in a thermal c[...]

D. J. Young, Auteur ; J. Zhang, Auteur ; C. Geers, Auteur |Recent experimental investigations have widened the understanding of metal dusting significantly. Microscopic observations have been used to dissect dusting mechanisms. Iron dusts by growing a cementite surface scale, which catalyses graphite nu[...]

J. Zhang, Auteur ; J.-M. Zhang, Auteur ; Wilson H. Tang, Auteur |Reliability-based optimization (RBO) intends to minimize the cost involved in a design while satisfying all technical requirements specified by using reliability theory. Although this idea is attractive, its implementation is generally difficult[...]

J. Zhang, Auteur ; J.-M. Zhang, Auteur ; Wilson H. Tang, Auteur |The performance of a slope, such as surviving a certain groundwater condition, can be viewed as the outcome of a full-scale test performed directly on the slope and may provide valuable information for safety assessment, upgrading analysis, and [...]

J. Zhang, Auteur ; X. L. Gong, Auteur ; W.-W. Song, Auteur |An imidazoline-based dissymmetric bis-quaternary ammonium gemini surfactant has been synthesized. Its surface active properties at equilibrium in water at 25 °C were determined. The inhibitive effect of the compound on Q235 steel in 1 M hydrochl[...]
