Vertical irregular buildings are frequently constructed across the globe for functional as well aesthetic purpose. However post-earthquake reconnaissance survey reports revealed high seismic vulnerability of building with vertical irregularities. Consequently it is very important to explore reason behind and poor performance structures during earthquake. A humble effort under taken considering ...

A complete characterization of field-aligned ionospheric irregularities responsible for the scintillation of transionospheric satellite signals includes not only their spectral properties (power spectral strength, spectral index, outer-scale, and anisotropy) but also their bulk motion, or drift. At low latitudes, the irregularity drift is predominantly zonal and controlled by the F region dynam...

Irregularities are inherent to virtually all fibers, including the conventional textile fibers, the high-performance brittle fibers and newly developed nano-fibers. These irregularities can fall into two main categories: dimensional or geometrical irregularity (external) and structural irregularity (internal). For natural fibers such as wool, diameter variation along fiber length is atypical ex...

For a graph G, the irregularity and total irregularity of G are defined as irr(G)=∑_(uv∈E(G))〖|d_G (u)-d_G (v)|〗 and irr_t (G)=1/2 ∑_(u,v∈V(G))〖|d_G (u)-d_G (v)|〗, respectively, where d_G (u) is the degree of vertex u. In this paper, we characterize all ‎connected Eulerian graphs with the second minimum irregularity, the second and third minimum total irregularity value, respectively.

BACKGROUND/PURPOSE The Irregularity Index is a measure of border irregularity from pigmented skin lesion images. The measure attempts to quantify the degree of irregularity of the structural indentations and protrusions along a lesion border. A carefully designed study has shown that the parameters derived from the Irregularity Index were highly correlated with expert dermatologists' notion of ...

Considering that the mechanical mechanism and energy release law of gradual failure columnar jointed basalt (CJB) are affected by lateral pressure, rock heterogeneity column irregularity, etc., numerical CJB models with various dip angles, irregularity degrees pressures were established through digital image correlation. The progressive process released CJBs simulated under loading rate 0.05 mm...

The irregularity strength of a graph G, s ( G ) , is the least k admitting { 1 2 … } -weighting edges assuring distinct weighted degrees all vertices, or equivalently possible maximal edge multiplicity in an irregular multigraph obtained via multiplying some its edges. most well-known open problem concerning this invariant conjecture posed 1987 by Faudree and Lehel that there exists constant C ...
