IC-Colorings and IC-Indices of graphs
Discrete Mathematics, 2005 The IC-index of a connected graph \(G\) is defined as the largest integer \(k\) with the following property: It is possible to assign positive integer labels to the vertices of \(G\) so that the labels sum to \(k\) and for any \(i=1,2,\dots,k-1\), there is a connected subgraph of \(G\) whose labels sum to \(i\).

Journal of Geophysical Research: Solid Earth, 2012 New measurements have been made of the friction coefficient of freshwater polycrystalline ice sliding slowly (5 × 10−8 to 1 × 10−3 m s−1) upon itself at temperatures from 98 to 263 K under low normal stresses (≤98 kPa). Sliding obeys Coulomb’s law: the shear stress is directly proportional to the normal stress across the interface, while cohesion ...

Wind turbines in icing conditions: performance and prediction [PDF]
Advances in Science and Research, 2011 Icing on structures is an important issue for wind energy developments in many regions of the world. Unfortunately, information about icing conditions is mostly rare due to a lack of measurements. Additionally, there is not much known about the operation

Multiwalled ice helixes and ice nanotubes [PDF]
Proceedings of the National Academy of Sciences, 2006 We report six phases of high-density nano-ice predicted to form within carbon nanotubes (CNTs) at high pressure. High-density nano-ice self-assembled within smaller-diameter CNT (17,0) exhibits a double-walled helical structure where the outer wall consists of four double-stranded helixes, which resemble a DNA double helix, and the inner wall is a ...
