Effects of the Centrifugal Pump Outlet Blade Angle on Its Internal Flow Field Characteristics under Cavitation Condition
Autor: Y. Y. Wang, W. G. Zhao, H. D. Han, P. J. Fan, Z. L. Liu, J. Q. Hu
Publikováno v: Journal of Applied Fluid Mechanics, Vol 16, Iss 2, Pp 389-399 (2022)
The outlet blade angle is a key geometrical parameter that governs how the impeller directly influences centrifugal pump performance. Therefore, a reasonable angle selection is crucial. To investigate the effects of the outlet blade angle on centrifu

Randomised trials with provision for early stopping for benefit (or harm): The impact on the estimated treatment effect
Autor: G. H. Guyatt, H D Han, Stephen D. Walter, Tim Ramsay, Matthias Briel, Dirk Bassler
Publikováno v: Statistics in Medicine. 38:2524-2543
Stopping rules for clinical trials are primarily intended to control Type I error rates if interim analyses are planned, but less is known about the impact that potential stopping has on estimating treatment benefit. In this paper, we derive analytic

A systematic survey of randomised trials that stopped early for reasons of futility
Autor: G. H. Guyatt, Neera Bhatnagar, Matthias Briel, H D Han, Stefan Schandelmaier, Dirk Bassler, Viktoria Gloy, Stephen D. Walter
Publikováno v: BMC Medical Research Methodology
BMC Medical Research Methodology, Vol 20, Iss 1, Pp 1-11 (2020)
Background Randomised trial protocols may incorporate interim analyses, with the potential to stop the study for futility if early data show insufficient promise of a treatment benefit. Previously, we have shown that this approach will theoretically

[Introduction of joint model and its applications in medical research]
Autor: Y H, Zhai, Q, Chen, H D, Han, X X, Zhao, Y Q, Gao, X, Zhou, J, He
Publikováno v: Zhonghua liu xing bing xue za zhi = Zhonghua liuxingbingxue zazhi. 40(11)
In medical follow-up studies, longitudinal data and survival data are often accompanied and associated with each other, thus respective analysis of longitudinal and survival data might lead to biased results. Joint model can correct deviations, impro

Estimation of supraglacial debris thickness using a novel target decomposition on L-band polarimetric SAR images in the Tianshan Mountains
Autor: Jixia Zhou, Qianwang Chen, H. D. Han, Z. Li, Baofeng Tian, Liangmin Huang, Yonglin Liu
Publikováno v: Journal of Geophysical Research: Earth Surface. 122:925-940
Debris is widely distributed in the ablation zones of mountain glaciers in the Tianshan Mountains. Supraglacial debris can accelerate or hamper glacier ablation, depending on its thickness. Thus, it plays an important role in the mass balance of debr
