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...

This paper presents an objective speech quality measure which is based on loudness patterns using the equivalent rectangular bandwidth (ERB) scale. The proposed measure, called the loudness pattern distortion (LPD), is computed from the differences between the loudness patterns of the original and processed speech. The LPD measure takes into account the transmission through the outer and middle...

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...
