Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Large deviations in random interlacements II: tilted interlacements and solidification of porous surfaces
随机交错 大偏差 倾斜交错 多孔表面 固化
2023/5/10
In this lecture, I will discuss how tilting and coarse graining, two key ideas in modern probability, come into play in deriving respectively the lower and upper bounds of the asymptotic probability i...
Optimal and hysteretic fluxes in alloy solidification: Variational principles and chimney spacing
alloy solidification Variational principles chimney spacing
2010/11/16
We take a numerical approach to analyze the mechanisms controlling the spacing of chimneys -- channels devoid of solid -- in two-dimensional mushy layers formed by solidifying a binary alloy. Chimneys...
Subaqueous sediment gravity flows undergoing progressive solidification
Subaqueous sediment gravity flows progressive solidification
2009/12/3
The flow-out potential of a body of fluidized sediment following abrupt collapse is discussed through numerical and physical modelling. The emphasis of the analysis procedure is placed on considering ...
Hazardous Wastes Disposal: Stabilization/Solidification of Tannery Residue in the Presence of Chromium
Cement Chromium Clay Leaching Solidification Stabilisation Tannery Waste
2011/12/16
Disposal or reuse of hazardous waste is a major consideration in chemical manufacturing and processing. Waste residuals from the tannery industry can contain high levels of chromium. Considered as a h...
Directional Solidification of Pure Succinonitrile and Succinonitrile- Salol Alloys
Organic alloys directional solidification microstructure and dendritic growth
2010/4/14
Pure succinonitrile (SCN) and succinonitrile-salol alloys with four different concentrations of salol were unidirectionally solidified at five different growth rates in a temperature gradient. The mic...
