Abstract: The study is to propose the local damage indices of composite frame structures consisting of high-strength concrete columns confined by continuous compound spiral ties and steel beams (CCSTRCS), the local damage indices would lay a foundation for the study of the overall damage indices for composite CCSTRCS frame. The Mehanny damage model has been modified to predict the local damage ...

S ince the original publication of the composite (Matsuda) index for the measurement of insulin sensitivity from plasma glucose and insulin concentrations during the oral glucose tolerance test (OGTT) (1), this index has been widely used by investigators throughout the world. According to Scopus, more than 1,000 articles have cited the original article (1) during the last 10 years, and several ...

The laser parasitic oscillations in active media under high pumping condition limit the gain of a high power amplifier system. This problem occurs due to existence of closed optical paths by internal reflections of active medium or systems. This problem can be overcome by eliminating the internal reflections by making rough surface, grooves, or antireflection coating or using index matching flu...

The study investigates whether the present pattern of urban development in India in the creation of mega cities is sustainable and what it can learn from the global megacities. This has been done by comparing the two Indian cities Mumbai and Bangalore with selected mega cities of the worlds representing different stages of development (Shanghai, London, and Singapore) using an indicator-based a...

the aim of this study was to compare the shear bond strength (sbs) of resin modified glass ionomer (rmgi) and composite resin for bonding metal and ceramic brackets.eighty-eight human premolars extracted for orthodontic purposes were divided into 4 groups (n=22). in groups 1 and 2, 22 metal and ceramic brackets were bonded using composite resin (transbond xt), respectively. twenty-two metal and...

In this paper we study the behavior of the second edge-Wiener index under the join and corona product of graphs. Results are applied for some classes of graphs such as suspensions, bottlenecks, and thorny graphs. 2010 Mathematics Subject Classification: 05C12; 05C62; 92E10

We introduce a modification of the Harary index where the contributions of vertex pairs are weighted by the sum of their degrees. After establishing basic mathematical properties of the new invariant, we proceed by finding the extremal graphs and investigating its behavior under several standard graph products.

In its Human Development R~7~ort IqgO, the United Nations Development Program (UNDP) proposes yet another composite indicator of development levels: the "'human development index'* (HDI). The HDI assesses intcrcountry development levels on the basis of three so-called deprivation indicators: life expectancy, adult literacy and the logarithm of purchasing power adjusted per capita GDP. Using sim...

The general sum-connectivity index is a molecular descriptor defined as [Formula: see text], where [Formula: see text] denotes the degree of a vertex [Formula: see text], and α is a real number. Let X be a graph; then let [Formula: see text] be the graph obtained from X by adding a new vertex [Formula: see text] corresponding to each edge of X and joining [Formula: see text] to the end vertices...
