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...

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....
