–The maintenance of pavements and particularly for flexible pavement is an essential requirement for the efficiency of highway network. For better serviceability, flexible pavements require more maintenance as compared to maintenance required for rigid pavements. But developing counties like India does not have sufficient budget or funds to satisfy the requirements. The maintenance & rehabilita...

In this paper we analyze periodic maintenance strategies for managing replicated objects in mobile wireless environments. Under periodical maintenance strategies, the system periodically checks local cells to determine if a replicated object should be allocated or deallocated in a cell to reduce the access cost. We develop a performance model based on Petri nets that considers the missing-read ...

The management of existing structures is raising a number pertinent questions to the owners and engineers. Many built more than 50 years ago (even those hundreds ago) usually no longer comply with safety requirements current codes, which are typically addressed in new structures. This not necessarily only caused by poor original design or degradation time, but it may be, for example, consequenc...

Maintenance is of necessity for sustaining machinery availability and reliability in order to ensure productivity, product quality, on-time delivery, and safe working environment. The costly maintenance strategies such as corrective maintenance and scheduled maintenance have been progressively replaced by superior maintenance strategies in which condition-based maintenance (CBM) is one of the d...
