This paper proposes an efficient method to determine entire reducts of incomplete decision tables according to the relational database approach. In the complex case, this algorithm has exponential computational complexity. However, this algorithm has polynomial computational complexity in the different cases of databases.

The melting points of the complexes were >350oC, indicating high thermal stability. Cu-Zn-containing complex showed the least binding energy against the three proteins. The bioactivity scores of the complexes were between -0.50 and 0.0. Against A549 Cu-Zn, Co-Zn and Fe-Zn containing complexes showed potential activity. Against MCF-7, Fe-Cu containing complex had IC50 of 53.5 whereas Co-Zn containing complex was active against HepG2. Three complexes were active against S. aureus in the tested range.

The conventional linear econometric and statistical models are not effective for forecasting the nonlinear and complex nature of crude oil prices. Computational intelligence techniques and hybrid modelling principles have been proposed to address this issue. Multiple forecasts can be combined using linear or nonlinear methods to create an aggregate forecast.

Ebook "Chemical reactions: Basic theory and computing" begins with the problem of determining the chemical reaction properties by first decomposing complex processes into their elementary components. Next, the problem of two colliding mass points is investigated and relationships between initial conditions and collision outcomes are discussed. The failure of classical approaches to match experimental information is discussed and a quantum formulation of the calculation of the properties of two colliding bodies is provided.
