In this paper, a new five-parameter lifetime and reliability distribution named “the exponentiated Uniform-Pareto distribution (EU-PD),” has been suggested that it has a bathtub-shaped and inverse bathtub-shape for modeling lifetime data. This distribution has applications in economics, actuarial modelling, reliability modeling, lifetime and biological sciences. Firstly, the mathematical and st...

Thermal residual stresses exist within a body in the absence of external loading or thermal gradients. Processing of the composites often involves cooling from higher temperature resulting in thermal residual stresses in the matrix due to restraint imposed by reinforcements. Thermal residual stresses determinately affect the properties of materials thereby shortening their lifetime. These resid...

Wireless sensor networks have many sensor nodes with a limited energy in a limited area. One of key issues in wireless sensor networks is to prolong the network lifetime. In this paper, we propose a scheme to construct an energy-efficient cluster structure in wireless sensor networks. Our scheme considers both the residual energy of sensor nodes and the number of neighbors around each node when...

Background and Objective: The gastric residual volume has a direct effect on the volume and timing of the subsequent feeding and causes gastric emptying and pulmonary aspiration. The present study compares the effect of Cydonia oblonga and Phyllanthus Emblica (Amla) fruit on gastric residual volume and pulmonary aspiration in mechanically- ventilated patients. Materials and Methods: This is a...

In this paper a new four-parameter lifetime distribution named “the Exponentiated gompertz-poisson (E-GP) distribution” has been suggested that it has a decreasing, increasing, bathtub-shaped and inverse bathtub-shape for modeling lifetime data. The Exponentiated gompertz-poisson has applications in economics, actuarial modelling,reliability modeling, lifetime and queuing problems and biologica...

We consider a unit with a random lifetime which is replaced at renewal times by a new identical one regardless of whether it has failed before or not. For this random periodic replacement policy we derive exact formulas for the cycle length, deened as the time between the replacements of two successive failed units, the stationary probability of the current unit to have failed, and the stationa...
