In this paper, we study the total edge irregularity strength of some well known graphs. An edge irregular total k-labeling φ : V ∪E → {1, 2, . . . , k} of a graph G = (V,E) is a labeling of vertices and edges of G in such a way that for any different edges xy and x′y′ their weights are distinct. The total edge irregularity strength tes(G) is defined as the minimum k for which G has an edge irre...

The propagation of surface waves in a fluid- saturated porous isotropic layer over a semi-infinite homogeneous elastic medium with an irregularity for free and rigid interfaces have been studied. The rectangular irregularity has been taken in the half-space. The dispersion equation for Love waves is derived by simple mathematical techniques followed by Fourier transformations.  It can be seen t...

The irregularity of skin lesion borders is a significant diagnostic factor when assessing a lesion for malignancy. A ranking experiment involving irregularity assessment showed poor average ranking correlation among 20 experienced clinicians (r=0.44). However, for 50% of the group correlation was high (r=0.81), indicating high degree of consensus. A quantitative measure of irregularity based on...

the total irregularity of a graph g is defined as 〖irr〗_t (g)=1/2 ∑_(u,v∈v(g))▒〖|d_u-d_v |〗, where d_u denotes the degree of a vertex u∈v(g). in this paper by using the gini index, we obtain the ordering of the total irregularity index for some classes of connected graphs, with the same number of vertices.

Crowding whether primary or secondary is one of the main reasons for seeking orthodontic treatment. Incisor irregularity is an easy and excellent indicator of the severity of crowding. Assessment of incisor irregularity on photocopied images can prove to be a good mean as an alternate to the conventional method of assessment on dental casts. In this study a sample of 58 dental casts were select...

Human languages are rule governed, but almost invariably these rules have exceptions in the form of irregularities. Since rules in language are efficient and productive, the persistence of irregularity is an anomaly. How does irregularity linger in the face of internal (endogenous) and external (exogenous) pressures to conform to a rule? Here we address this problem by taking a detailed look at...

In modern urban construction, irregular buildings are increasingly constructed to fulfill architectural and functional requirements. However, these revealed unfavorable seismic performance during the past earthquake records. When design codes deal with issue of building irregularity, little attention is paid location irregularity. current study, a detailed structural analysis was performed inve...
