ON DETECTING NEW BETTER THAN USED PROPERTY OF LIFE DISTRIBUTIONS

A test Procedure is proposed for testing the null hypothesis that two life distribution are equal against the alternative that one is more new better than used than the other. The asymptotic normally of the proposed class of test statistics is established

ON SELECTING BEST IFRA POPULATION:A LARGE SAMPLE APPROACH

The Principles Problem of ranking and selection is to select the Best Population among the several population are usually based on the some parameters of the underlyning family.one such way to select a population that belongs to some parametric family

ON TESTING EXPONENTIALITY AGAINST NEW BETTER THAN USED ALTERNATIVES

In this paper the problem is investigated how to prove that after a specified timet0of operation the conditional survival probability of an item is less than the correspondingsurvival probability of a new item. This problem occurs in various areas like for instance inindustry, when designing a maintenance policy. For a randomly censored sample, test statisticsare derived for testing the null hypothesis that a new item has stochastically the same residuallife length as does a used item of specified age t0versus the alternative hypothesis that a newitem has stochastically a longer residual life length as does a used item of specified age t0.The tests are based on the asymptotic distribution of the test statistics and selected using thePitman asymptotic relative efficacy. Since small samples are prevailing in reliability testing,further research is needed, which omits the asymptotic derivation On testing exponentiality against new better than used of specified age (PDF Download Available).

The Behavior of Banyan (B)/Banana (Ba) Fibers Reinforced Hybrid Composites Influenced by Chemical Treatment on Tensile, Bending and Water Absorption Behavior: An Experimental and FEA Investigation

Natural fiber-based composites are highly prioritized in present industries due to their properties and benefits over synthetic fibers. Due to their biodegradable nature, banyan and banana fibers were used for the present work. This paper deals with an experimental and FEA investigation of the tensile and bending behavior of banyan (B) and banana (Ba)-reinforced composites with different volume fractions, such as 25B/25Ba, 30B/20Ba, and 35B/15Ba, with a 50% weight fraction of epoxy resin and different fiber orientations. The hybrid composites treated with a 5% NaOH solution have better results as compared to untreated hybrid composites, with a volume fraction of 30% banyan fibers and 20% banana fiber (30B/20Ba), giving greater tensile and flexural properties for both treated and untreated fiber composites when compared to other volume fraction composites at 0/0/0/0 orientation. The maximum tensile and bending strength was found in the 30B/20Ba volume fractions to be 63.37 MPa and 67.07 MPa, respectively. For treated fiber composites, water absorption increases with an increase in the duration of immersion in composites up to 144 h
