Computational aspects of hydroformylation

The influence of transition metal complexes as catalysts upon the activity and selectivity of hydroformylation reactions has been extensively investigated during the last decades. Nowadays computational chemistry is an indispensable tool for elucidation of reaction mechanisms and for understanding the various aspects which govern the outcome of catalytic reactions. This review attempts to surve...

Some Computational Aspects

The only thing that is certain and absolute about Nature is its patchiness. Patchiness is ubiquitous, occurring across systems, organizational levels, and spatio-temporal scales. Traditional modeling approaches in ecology often fail to recognize spatial patchiness because they usually assume spatial homogeneity. A landscape may be viewed as a hierarchical mosaic system of patches that are diffe...

Computational Aspects of NUCOMP

In 1989, Shanks introduced the NUCOMP algorithm [10] for computing the reduced composite of two positive definite binary quadratic forms of discriminant ∆. Essentially by applying reduction before composing the two forms, the intermediate operands are reduced from size O(∆) to O(∆) in most cases and at worst to O(∆). Shanks made use of this to extend the capabilities of his hand-held calculator...

Computational Aspects of M-grammars

In this paper M-grammars tha t are used in the Roset ta t ranslat ion system will be looked at as the specification of a t t r ibu te grammars. We will show tha t the a t t r ibute evaluation order is such tha t instead of the special-purpose parsing and generation algorithms introduced for M-grammars in Appelo et al.(1987), also Earley-like context-free parsing and ordinary generation strategi...
