Based on a generalized cumulative damage approach with a stochastic process describing degradation, new accelerated life test models are presented in which both observed failures and degradation measures can be considered for parametric inference of system lifetime. Incorporating an accelerated test variable, we provide several new accelerated degradation models for failure based on the geometr...

Stability studies play a critical role in assuring product quality at all points in the vaccine life cycle. These studies used to determine vaccine expiry date and vaccine efficacy. Accelerated stability and long term stability study performed for three batches of trivalent oral poliomyelitis vaccine (OPV) and three batches of monovalent OPV (type1) manufactured by Razi institute. After samplin...

In this paper a Bayesian approach for accelerated life testing will be considered. It will be assumed that the failure times at the different stress levels follow a Weibull distribution and exponential distribution, respectively. In accelerated life tests, the components are exposed to an environment that is more severe that the usual environment, such that the components will fail in a shorter...

In March 2014, Congress passed legislation to halt discounted flood insurance premiums from increasing to full-risk levels. The rate hike was authorized two years earlier by the Biggert-Waters Act to address the National Flood Insurance Program’s structurally induced $24 billion debt. The recent developments highlight the tension between risk-based premium and affordability of flood insurance f...

1. Rapid deployment and employment. In addition to maintaining a modestly sized but potent force in the theater on a routine basis, the United States requires assets to ensure that forces essential to the halt campaign can arrive in the theater within days and conduct high tempo operations. Strategic airlift constitutes the backbone of this early deployment capability. It should be supplemented...

After several decades of rapid technological advancement and economic growth, levels of pollution and environmental degradation are rising all over the world. Unilateral response on the part of one single country would hardly be effective. Collaborations in pollution abatement, R&D in technology development, emissions reduction, and subsidization for technology transfer offer the best promise t...

Already, the formation of the WTO did not halt the proliferation of new RTAs. There has been an enormous increase in Preferential Trade Agreements (PTAs) in the last twenty years. In fact, RTAs legitimacy is well recognised under GATT/WTO. By their very nature, such arrangements favour imports from members of the grouping and discriminate against imports from other countries. This departure fro...
