Approximate Gaussian Elimination

During their rapid economic development and industrialization, megacities in the developing nations with high populations (especially east south Asia) are plagued by severe air pollution problems (e.g., heavy haze), which impose a threat not only to public health but also sustainable of society economy. To relieve burden for general public, this article reviewed several geoengineering measures ...

Abstract The fast increase of population results in the quick development industry and agriculture. Large amounts contaminants such as metal ions organic are released into natural environment, posing a risk to human health causing environment ecosystem problems. efficient elimination from aqueous solutions, photocatalytic degradation pollutants or in-situ solidification/immobilization heavy sol...

Variable Elimination (VE) is the most basic one of many Bayesian network inference algorithms. The speed and complexity reasoning mainly depend on order elimination. Finding optimal elimination a Nondeterministic Polynomial Hard (NP-Hard) problem, which often solved by heuristic search in practice. In to improve variable method, minimum, maximum potential, minimum missing edge added methods are...

In some temporal reasoning systems, inequations can give rise to disjunctions of inequa-tions when variable elimination is performed. Motivated by this observation, we extend previous research on temporal constraints by considering disjunctions of inequations (under the assumption that time is dense.) We present results on consistency checking, canonical forms and variable elimination for this ...

Elemental mercury (Hg0) and selenium species (Se0 SeO2) are two typical unsolved pollutants in coal combustion flue gas due to their high volatility. The interactions between Hg0 play an important role the pollution control. Thus, co-adsorption of on pyrite surface was calculated based density functional theory (DFT), adsorption systematically investigated. Although there is a weak attraction S...
