We initiate the study of graph classes of power-bounded clique-width, that is, graph classes for which there exist integers k and ℓ such that the kth powers of the graphs are of clique-width at most ℓ. We give sufficient ...

A non-redundant, three-stage, 27-level inverter using "H" converters, is analysed for machine drive applications. The main advantage of this converter is the optimisation of levels with a minimum number of semiconductors. ...

In populational studies, the weight/width carapace relationship analysis, can furnish indications about the individual physiological variations as a function of the environment, and it can indicate sexual dimorphism. The ...

Introduction. Leaf area is often related to plant growth, development, physiology and yield. Many non-destructive models have been proposed for leaf area estimation of several plant genotypes, demonstrating that leaf length, ...

The detection of cracks is an important monitoring task in civil engineering infrastructure devoted to ensuring durability, structural safety, and integrity. It has been traditionally performed by visual inspection, and ...

It is shown that Halin graphs are -edge-choosable and that graphs of tree-width 3 are -edge-choosable and -total-colourable.
