ABSTRACT: The influence of viscous dissipation on laminar flow and heat transfer of a viscous incompressible fluid due to a stretching porous sheet subjected to power law heat flux in presence of heat source is studied. The equations of motion and heat transfer are transformed into a system of dimensionless non-linear ordinary differential equations which solved numerical by using shooting technique. The effects of porosity parameter, Eckert number, Prandtl number and heat source parameter on the velocity profile, temperature distribution and recovery temperature are discussed.

ABSTRACT: This paper deals with estimating failure time data under step-stress partially accelerated life tests based on type I censoring. The lifetime distribution of the test items is assumed to follow Mukherjee-Islam failure model. The maximum likelihood estimates (MLEs) are obtained for the distribution parameters and acceleration factor. In addition, asymptotic variance and covariance matrix of the estimators are given. Furthermore, confidence intervals of the estimators are presented. For illustrating the precision and variations of maximum likelihood estimators, simulation studies are introduced.
