The Beta Inverse Weibull distribution is one of the widely applied distribution. In reliability and biological studies, we can model failure rates by this distribution. In this paper, we extend the study of the Beta Inverse Weibull distribution (BIW). The unimodal BIW with three parameters are estimated by the Method of Quantile Estimates (MQE) and then compared with parameters estimated by the Maximum Likelihood Estimates (MLE). To estimate the model parameters, Newton-Raphson method is applied for MLE and Nelder-Mead Simplex method is applied for MQE and the table of simulation results is shown. Finally, practical use of the model is demonstrated by dint of an application to real data. For the real data computation, standard deviations of the estimated parameters are calculated by random permutation method.

Antigonon leptopus (Polygonaceae) is an evergreen climber native to Mexico. The parts of this plant like seeds, tubers and flowers are consumed as food in several parts of the world. Tea prepared from aerial parts is used as a cold remedy and pain relief. The leaves are used for diabetes, urinary problems, low blood pressure and as a heart tonic. It also has Xanthine oxidase inhibitor and anticancer activity. Though pharmacogostic evaluation of other plant parts of Antigonon leptopus is already carried out, no standards are available for the leaf. The present study has been carried out for the authentication and to lay down the standards for the identification of the leaves. Therefore, the fresh leaves and dried powder is used for the microscopical, macroscopical, physicochemical and fluorescence analysis.

Aluminium based metal matrix composites are finding wider usage in most of the engineering applications owing to their excellent mechanical properties. These composites are prepared by liquid metallurgy route. The quality of castings produced by this method largely depends on the rate of cooling during the solidification of the composite melt. It is therefore, very much essential for the foundry technologists to understand the solidification phenomenon and control the influencing variables resulting in sound quality castings. In the present work, casting simulation is carried out for LM25 aluminium alloy and its silicon carbide particle composites using commercially available CASTDESIGNER™ software. The simulated cooling curves are experimentally verified and found to be in good agreement.
