The macroeconomic uncertainty created by COVID-19 is hard to measure. The situation demands simultaneous policy intervention in terms of public health infrastructure and livelihood. Along with the global community, India ...
In this paper, increasing convex (concave)Total Time on Test (TTT) transform of a lifetime
random variable is considered.In order to identify the failure rate model of functions of random variables, the TTT of transformed ...
Lifetime distributions for many components usually have a bathtub shape for its failure rate function in practice. However, there are a very few distribution have bathtub shaped failure rate function.Models with bathtub-shaped ...

The inhibiting capacity of Tinospora cordifolia extract (TCE) was evaluated on mild steel in 1 M HCl and 0.5 M H2SO4 by physicochemical and electrochemical techniques and by utilizing statistical tools such as response ...
In recent times, there is a growing trend among researchers in utilizing plant based starting materials to synthesize functional nanomaterials. Toward this goal, cashew nut shell oil-derived cardanol caught great attention ...
Usually, systems and components are described as being in one of two modes, “on”or “off.” Such systems are described using binary structure functions. In multistatesystems (MSS), components can be in more than two states—for ...
In this paper we model an open queueing network of cardiac treatment section in medical sector. Assume arrival of patients follows Poisson and service times at stations have exponential distribution. The performance measures ...
Dielectric constant variation with temperature for different wax sampies is analysed with the help of split ring resonators (SRRs). The method employs a simple extraction procedure to obtain the unknown permittivity values ...
In this paper, mixture of Exponential and Weibull distributions is considered for modelling real lifetime data. The basic mathematical properties including moments, generating functions, order statistics etc are derived. ...
Most real life system exhibit bathtub shapes for their failure rate functions.
Generalized Lindley, Generalized Gamma, Exponentiated Weibull and xExponential distributions are proposed for modeling lifetime data having ...
