a r t i c l e i n f o A hydration kinetics model for Portland cement is formulated based on thermodynamics of multiphase porous media. The mechanism of cement hydration is discussed based on literature review. The model is then developed considering the effects of chemical composition and fineness of cement, water–cement ratio, curing temperature and(More)
A new use of smoothed particle hydrodynamics (SPH) in fluid simulation is presented: an algorithm solving the Helmholtz-Hodge decomposition using SPH in order to find the null divergence velocity field for incompressible flow simulation. Accordingly, a new version of the Laplacian for a vector field is proposed here. In order to improve the accuracy of the(More)
A multiple-frequency inverse scattering method that uses eigenfunctions of a scattering operator is extended to image large-scale and high-contrast objects. The extension uses an estimate of the scattering object to form the difference between the scattering by the object and the scattering by the estimate of the object. The scattering potential defined by(More)
The objective of the study is to present the modeling and multi-objective optimization of NO x conversion efficiency and NH 3 slip in the Selective Catalytic Reduction (SCR) catalytic converter for a diesel engine. A novel ensemble method based on a support vector machine (SVM) and genetic algorithm (GA) is proposed to establish the models for the(More)
The asymmetric unit of the title compound, C(8)H(9)N(2) (+)·C(8)H(5)O(4) (-), contains two independent ion pairs. In each 2-methyl-1H-benzimidazolium ion, an intra-molecular O-H⋯O bond forms an S(7) graph-set motif. In the crystal, the components are linked by N-H⋯O hydrogen bonds, forming chains along [210]. Further stabilization is provided by weak C-H⋯O(More)
