Quasi-Monte-Carlo methods are well-known for solving di erent problems of numerical analysis such as integration, optimization, etc. The error estimates for global optimization depend on the dispersion of the point sequence with respect to balls. In general, the dispersion of a point set with respect to various classes of range spaces, like balls, squares, triangles, axis-parallel and arbitrary...

Nominal Classification Gunter Senft

The problem of "classification" is a general problem of life. That classification abilities are necessary for the survival of every organism is an important insight of biology. Human beings classify consciously, unconsciously, and even subconsciously in all situations. When we confront a scientific problem, we try to solve it by first classifying the various parts of the problem. Therefore, the...

Selective removal of acetylenes from olefin mixtures through specific physicochemical interactions of ionic liquids with acetylenes.

Imidazolium-based ionic liquids (ILs) bearing an alkylphosphite anion, were highly efficient for the selective removal of acetylenes in olefins. Comparison of solubility data at 313 K and at atmospheric pressure shows that the solubilities of acetylene and propyne in 1,3-dimethylimidazolium methylphosphite ([DMIM][MeHPO(3)]) are about 45 and 20 times higher than those of ethylene and propylene,...
