Condition monitoring involves the use of sensors and data acquisition equipment to assess the quality of a given process by determining the health of its components. Machinery condition monitoring, which affords one the ability to implement condition-based maintenance (as opposed to time-based maintenance or run to failure) assesses the health of critical machinery components to reduce catastro...

in order to perform preventive maintenance (pm), two approaches have evolved in the literature. the traditional approach is based on the use of statistical and reliability analysis of equipment failure. under statistical-reliability (s-r)-based pm, the objective of achieving the minimum total cost is pursued by establishing fixed pm intervals, which are statistically optimal, at which to replac...

the baluarte do cavaleiro is part of the stone masonry wall system existing in the city ofchaves of portugal and it is a construction dated from the xvii century. the baluarte docavaleiro is formed by three walls (north-east, ne; south-east, se; south-west, sw) andby two junction elements (designated here by cunhais). the se wall has suffered twocollapses recently. the main objective of this re...

The Circuit Breaker (CB) is one of the most important equipment in power systems. CB must operate reliably to protect power systems as well as to perform tasks such as load disconnection, normal interruption, and fault current interruption. Therefore, the reliable operation of CB can affect the security and stability of power network. In this paper, effects of Condition Monitoring (CM) of CB on...

The development of structural health monitoring (SHM) technology has evolved for over fifteen years in Hong Kong since the implementation of the “Wind And Structural Health Monitoring System (WASHMS)” on the suspension Tsing Ma Bridge in 1997. Five cable-supported bridges in Hong Kong, namely the Tsing Ma (suspension) Bridge, the Kap Shui Mun (cable-stayed) Bridge, the Ting Kau (cable-stayed) B...

there are several strategies for maintenance and repairing of devices in industry. however, they are still confronted with many uncertainties. a hydraulic lifting device after ten years of working in a technical center in isfahan is faced with uncertainty in terms of reliability. being able to know the reliability of pieces means predicting failure occurrences, which is accomplished by conditio...

In modern times, far-reaching changes especially in production have taken place. Lean manufacturing systems require delivery strategies such as just-in-time or just-in-sequence that are synchronized with production demand to make sure the optimal amount of inventory is on hand at any time. This development comes along with both increasing dependence and cross-linking of inhouse-logistics system...
