In this paper, we discuss the prediction problem based on censored coherent system lifetime data when the system structure is known and the component lifetime follows the proportional reversed hazard model. Different point and interval predictors based on classical and Bayesian approaches are derived. A numerical example is presented to illustrate the prediction methods used in this paper. Mont...

Accurately predicting the lifetimes of objects in object-oriented and functional languages is important because such predictions can be used to improve memory management performance at run-time. A typical approach to this prediction problem is first to observe object lifetimes by tracing a sample program execution, then to construct a predictor function based on these observations, and finally ...

Nowadays, the technology intends to use materials such as magnesium alloys due to their high strength to weight ratio in engine components. As usual, engine cylinder heads and blocks has made of various types of cast irons and aluminum alloys. However, magnesium alloys has physical and mechanical properties near to aluminum alloys and reduce the weight up to 40 percents. In this article, a new ...

In Vehicular ad hoc networks (VANET), a host may exhaust its power or move away without giving any notice to its cooperative nodes, causing changes in network topology, and thus, these changes may significantly degrade the performance of a routing protocol. Several routing protocol studies based on node lifetime and link lifetime have been done to address this problem. We propose a new algorith...

Useful lifetime evaluation of chevron rubber spring was very important in design procedure to assure the safety and reliability. It is, therefore, necessary to establish a suitable criterion for the replacement period of chevron rubber spring. In this study, we performed characteristic analysis and useful lifetime prediction of chevron rubber spring. Rubber material coefficient was obtained by ...
