Although the Gini coefficient is an ideal measure of income inequality, it may be applied to measure the aging inequality in a society. In this paper, an attempt has been made to develop alternative measures of aging inequality based on the Gini index. The study uses the secondary population data of Asian countries collected from the international data base, US census Bureau. From the analysis ...

This paper presents a fabrication process in which all components of an in-plane piezoresistive accelerometer are fabricated simultaneously using a single mask. By dry-etching a silicon-on-insulator (SOI) wafer that has a specific resistivity, piezoresistors are defined and isolated from each other and from the bulk silicon without the pn-junctions normally required in piezoresistive sensors. I...

As urbanization increases, urban runoff becomes an increasingly more important component of urban non-point pollution. In this study, the Storm Water Management Model was used to simulate the quantity and quality of runoff in a highly urbanized catchment. Data from three rainfall events were collected and used for model calibration and validation. Model performance was assessed using the Nash-S...

Fast electromagnetic drive mechanism shows broad application prospects in many areas, but there is still a lack of unified evaluation parameters as to evaluate the dynamic characteristics due to diversity and complexity of the mechanisms. Three interrelated evaluation parameters are presented for topology analysis, namely the electromagnetic force sensitivity coefficient, the initial time const...

To circumvent the limitations of the tests for coefficients of variation and Sharpe ratios, we develop the mean-variance-ratio statistic to test the equality of the meanvariance ratios and prove that our proposed statistic is uniformly most powerful unbiased. In addition, we illustrate the applicability of our proposed test to compare the performances of stock indices.

This paper deals with the heat exchange performance prediction of a counter flow double-tube condenser for binary natural refrigerant mixtures (propane/n-butane & propane/i-butane ). The local characteristics of the heat transfer and pressure drop are calculated using a prediction method developed by authors, and the total pressure drop, the overall heat transfer coefficient and the average hea...

In this paper, the structure optimization scheme of multi-layer absorber on surface human tissue is designed. The uses graphite, foam and other materials to build a resistance loss layer. Solve electromagnetic parameters graphite through its characteristics, use equivalent transmission line theory calculate reflection coefficient. Establish objective function coefficient, genetic algorithm opti...

The relationship between structure and inhibition activity on carbonic anhydrase I of a set of forty substituted 1,3,4-thiadiazoleand 1,3,4-thiadiazoline-disulfonamides has been investigated by using the Molecular Descriptors Family method. The molecular descriptors family has been generated starting with the information obtained from the compounds structure and the descriptors were calculated....
