Effect of CA bacteria on the carbonation process of γ-C2S

Carbonation has been proven to be a promising way to improve the mechanism properties and durability of steel slag products. CA bacteria can promote the hydration of CO2. In this study, one kind of alkali-resistant CA bacteria was chosen to investigate its effects on the carbonation process of γ-C2S. Results showed that bacteria could increase...

A case study of taxiway landing (1982-2016)

The paper reviews the 26 “landing on the taxiway” cases happened between 1982 and 2016 recorded by the National Transportation Safety Board (NTSB) aviation accident/incident database, it evaluates causal and contributing factors such as visibility, navigation, preparation, fatigue, experiences, age and more affecting pilots’ operations. Also,...

The Conversion from CityGML to 3D Property Units

Due to the fast growth of building construction technology and increasing demands on the efficient use of land, human living space are expanded from on the surface to above and under the earth surface. It raises the need for three dimentional (3D) cadastral by realizing that the current cadastral system based on 2D is not appropriate to reflect...

Fast time domain integral equation based electromagnetic analysis: A maturing technosclogy

The analysis of transient scattering from perfectly conducting as well as potentially inhomogeneous penetrable bodies often is effected using marching on in time based time domain integral equation methods. This paper reviews the state of the art in the field, highlighting recent advances that address not only their stability and computational...
