A topographic mechanism for arcing of dryland vegetation bands [PDF]
Journal of the Royal Society Interface, 2018 Banded patterns consisting of alternating bare soil and dense vegetation have been observed in water-limited ecosystems across the globe, often appearing along gently sloped terrain with the stripes aligned transverse to the elevation gradient.

Erosion of nanostructured tungsten by laser ablation, sputtering and arcing
Nuclear Materials and Energy, 2017 Mass loss of nanostructured tungsten, which was formed by helium plasma irradiation, due to laser ablation, sputtering, and arcing was investigated. Below the helium sputtering energy threshold (200eV.

A method for determining arc breakdown in low-voltage electrical networks [PDF]
Serbian Journal of Electrical Engineering, 2023 In low voltage distribution networks, there is a high risk of fires caused by wiring faults that lead to short circuits. Arcing protection devices (ARCs) already exist, but experiments show that they also often do not disable such faults.

Commentationes Mathematicae Universitatis Carolinae, 2018 The arc graph $ (G)$ of a digraph $G$ is the digraph with the set of arcs of $G$ as vertex-set, where the arcs of $ (G)$ join consecutive arcs of $G$. In 1981, Poljak and R dl characterised the chromatic number of $ (G)$ in terms of the chromatic number of $G$ when $G$ is symmetric (i.e., undirected).

ARC Detection in DC ARC Furnaces [PDF]
, 2014 A direct-current (DC) plasma arc furnace is a type of electric furnace used for metallurgical operations. The successful operation of DC furnaces depends to a large extent on gaining a fundamental understanding of the arc phenomenon itself, and ensuring its presence in the furnace at all times.

Bulletin of the Belgian Mathematical Society - Simon Stevin, 2006 An arc in a projective plane whose secants meet some exterior line in the minimum number of points is said to be hyperfocused on that line. Such arcs are related to geometrically based secret sharing schemes. A \(k\)-arc \(\mathcal{K}\) is sharply focused on a line \(\ell\) which is external to \(\mathcal{K}\) if the \({k\choose2}\) secants of ...
